Of course, IBM is going all out on the social media side as well:
It's that time again. Every year, IBM hosts the "System Storage Technical University". I have been going to these since they first started in the 1990s. This time we are at the lovely [Hilton Orlando] in Orlando, Florida.
For those who want to relive past events, here are my blog posts from this event in 2010:
As was the case last year, IBM once again will run this conference alongside the [IBM System x Technical University] the same week, in the same hotel. This allows attendees to cross over to the other side to see a few sessions of the other conference. I took advantage of this last year, and plan to do so again this year as well!
For those on Twitter, you can follow my tweets at [@az990tony] or search on the hash tag #ibmtechu.
Maria Boonie is the IBM Director for IBM Worldwide Training and Technical Conferences. She indicated that there were 1500 attendees this week crossing both the System Storage and System x conferences at this hotel. There are 35 vendors that have sponsored this event, and they will be at the "Solutions Center" being held Monday through Wednesday this week.
She took this opportunity to plug IBM's latest education offerings, including Guaranteed-to-Run implementation classes, and Instructor-Led Online (ILO) technical classes.
Brian Truskowski is IBM General Manager for System Storage and Networking. I used to directly report to him in a previous role, and a few years ago he used to be the IBM CIO that helped with IBM's internal IT transformation.
Brian indicates that the previous approach to growth was to "Just Buy More", but this has some unintended consequences. He argued that companies need to adopt one or more of the following approaches to growth:
Stop storing so much - reduce data footprint using storage efficiency capabilities like data deduplication and compression
Store more with what is already on the floor - improve storage utilization with technologies like storage virtualization and thin provisioning
Move data to the right place - implement automated tiering, such as "Flash & Stash" between Solid-state drives and spinning disk, and/or Information Lifecycle Management (ILM) between disk and tape. Studies at some clients have found over 70 percent of data has not beed touched in the last 90 days
This time of dramatic change is the result of a "perfect storm" of influences, including the rising costs and risks associated with losing data, the increased need to index and search data, the desire for "Business Analytics", and the expectation for 100 percent up-time. This is driving IBM to offer hyper-efficient backup, Continuous Data Availability, and Smart Archive solutions.
The case study of SPRINT is a good example. SPRINT is a Telecommunications provider for cell phone users. They were challenged with 35 percent utilization, 165 storage arrays from six different vendors, and an expected 100 percent increase in their IT maintenance costs. After implementing IBM SAN Volume Controller (SVC) and Tivoli Storage Productivity Center (TPC) to manager 2.9 PB of data, SPRINT increased their utilization to 82 percent, reduced down to 70 storage arrays from only three vendors, and reduced their maintenance costs by 57 percent. Today, SPRINT now manages over 5 PB of data with SVC and TPC, have reduced their power and cooling by 3.5 million KWh, representing $320,000 USD in savings.
Roland Hagan is the IBM Vice President for the System x server platform. He talked about the "IT Conundrum" that represents a vicious cycle of "IT Sprawl", "Untrusted Data" and "Inflexible IT" that seem to feed each other. IBM is trying to change behavior, from thinking and dealing with physical boxes representing servers, storage and network gear, to a more holistic view focused on workloads, shared resource pools, independent scaling, and automated management.
IBM is leading the server marketplace, in part because of clever things IBM is doing, especially in developing the eX5 chipset that surrounds x86 commondity processors, and in part because of actions or decisions the competition have taken:
It doesn't break IBM's heart that Oracle decided to drop software support of their database on Itanium, which focued entirley against HP. Oracle runs on IBM servers better than Oracle/Sun or HP servers today, so it does not impact us, other than IBM has had a lot of people leaving HP to switch over to IBM.
HP has taken on a new CEO and reduced their R&D budget, causing them to be late-to-market on some of their offerings.
Dell continues to focus on the small and medium sized customer, and have not really broken into the "Enterprise".
Newcomer Cisco has some great technology that only seems to be adoptable in "Green Field" situations, as it does not integrate well with existing data center infrastructures.
The combination of ex5 chip-set architecture, Max5 memory expansion capabilities and Virtual Network Interface Cards (NICs), provide for a very VM-aware platform. For those who are not ready to fully adopt an integrated stack like IBM CloudBurst, IBM offers the Tivoli Service Automation software on its own, and a new [IBM BladeCenter Foundation for Cloud] as stepping stones to get there.
There are certainly more attendees here than last year, which reflects either the change in location (Orlando, Florida rather than Washington DC) as well as the economic recovery. I'm looking forward to an excellent week!
Jim is an IBM Fellow for IBM Systems and Technology Group. There are only 73 IBM Fellows currently working for IBM, and this is the highest honor IBM can bestow on an employee. He has been working with IBM since 1968.
He is tasked with predicting the future of IT, and help drive strategic direction for IBM. Cost pressures, requirements for growth, accelerating innovation and changing business needs help influence this direction.
IBM's approach is to integrate four different "IT building blocks":
Scale-up Systems, like the IBM System Storage DS8000 and TS3500 Tape Library
Resource Pools, such as IBM Storage Pools formed from managed disks by IBM SAN Volume Controller (SVC)
Integrated stacks and appliances, integrated software and hardware stacks, from Storwize V7000 to full rack systems like IBM Smart Analytics Server or CloudBurst.
Mobility of workloads and resources requires unified end-to-end service management. Fortunately, IBM is the #1 leader in IT Service Management solutions.
Jim addressed three myths:
Myth 1: IT Infrastructures will be homogenous.
Jim feels that innovations are happening too rapidly for this to ever happen, and is not a desirable end-goal. Instead, a focus to find the right balance of the IT building blocks might be a better approach.
Myth 2: All of your problems can be solved by replacing everything with product X.
Jim feels that the days of "rip-and-replace" are fading away. As IBM Executive Steve Mills said, "It isn't about the next new thing, but how well new things integrate with established applications and processes."
Myth 3: All IT will move to the Cloud model.
Jim feels a substantial portion of IT will move to the Cloud, but not all of it. There will always be exceptions where the old traditional ways of doing things might be appropriate. Clouds are just one of the many building blocks to choose from.
Jim's focus lately has been finding new ways to take advantage of virtualization concepts. Server, storage and network virtualization are helping address these challenges through four key methods:
Sharing - virtualization that allows a single resource to be used by multiple users. For example, hypervisors allow several guest VM operating systems share common hardware on a single physical server.
Aggregation - virtualization that allows multiple resources to be managed as a single pool. For example, SAN Volume Controller can virtualize the storage of multiple disk arrays and create a single storage pool.
Emulation - virtualization that allows one set of resources to look and feel like a different set of resources. Some hypervisors can emulate different kinds of CPU processors, for example.
Insulation - virtualization that hides the complexity from the end-user application or other higher levels of infrastructure, making it easier to make changes of the underlying managed resources. For example, both SONAS and SAN Volume Controller allow disk capacity to be removed and replaced without disruption to the application.
In today's economy, IT transformation costs must be low enough to yield near-term benefits. The long-term benefits are real, but near-term benefits are needed for projects to get started.
What set's IBM ahead of the pack? Here was Jim's list:
100 Years of Innovation, including being the U.S. Patent leader for the last 18 years in a row
IBM's huge investment in IBM Research, with labs all over the globe
Leadership products in a broad portfolio
Workload-optimized designs with integration from middleware all the way down to underlying hardware
Comprehensive management software for IBM and non-IBM equipment
Clod is an IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage. His presentation focused on trends and directions in the IT storage industry. Clod started with five workload categories:
To address these unique workload categories, IBM will offer workload-optimized systems. The four drivers on the design for these are performance, efficiency, scalability, and integration. For example, to address performance, companies can adopt Solid-State Drives (SSD). Unfortunately, these are 20 times more expensive dollar-per-GB than spinning disk, and the complexity involved in deciding what data to place on SSD was daunting. IBM solved this with an elegant solution called IBM System Storage Easy Tier, which provides automated data tiering for IBM DS8000, SAN Volume Controller (SVC) and Storwize V7000.
For scalability, IBM has adopted Scale-Out architectures, as seen in the XIV, SVC, and SONAS. SONAS is based on the highly scalable IBM General Parallel File System (GPFS). File systems are like wine, they get better with age. GPFS was introduced 15 years ago, and is more mature than many of the other "scalable file systems" from our competition.
Areal Density advancements on Hard Disk Drives (HDD) are slowing down. During the 1990s, the IT industry enjoyed 60 to 100 percent annual improvement in areal density (bits per square inch). In the 2000s, this dropped to 25 to 40 percent, as engineers are starting to hit various physical limitations.
Storage Efficiency features like compression have been around for a while, but are being deployed in new ways. For example, IBM invented WAN compression needed for Mainframe HASP. WAN compression became industry standard. Then IBM introduced compression on tape, and now compression on tape is an industry standard. ProtecTIER and Information Archive are able to combine compression with data deduplication to store backups and archive copies. Lastly, IBM now offers compression on primary data, through the IBM Real-Time Compression appliance.
For the rest of this decade, IBM predicts that tape will continue to enjoy (at least) 10 times lower dollar-per-GB than the least expensive spinning disk. Disk and Tape share common technologies, so all of the R&D investment for these products apply to both types of storage media.
For integration, IBM is leading the effort to help companies converge their SAN and LAN networks. By 2015, Clod predicts that there will be more FCoE purchased than FCP. IBM is also driving integration between hypervisors and storage virtualization. For example, IBM already supports VMware API for Array Integration (VAAI) in various storage products, including XIV, SVC and Storwize V7000.
Lastly, Clod could not finish a presentation without mentioning Cloud Computing. Cloud storage is expected to grow 32 percent CAGR from year 2010 to 2015. Roughly 10 percent of all servers and storage will be in some type of cloud by 2015.
As is often the case, I am torn between getting short posts out in a timely manner versus spending some more time to improve the length and quality of information, but posted much later. I will spread out the blog posts in consumable amounts throughout the next week or two, to achieve this balance.
IBM Information Archive for email, files and eDiscovery
Not too many people have heard of IBM's Smart Archive strategy and the storage products IBM offers to meet compliance regulations. This session covered the following:
The differences between backup and archive, including a few of my own personal horror stories helping companies who had foolishly thought that keeping backup copies for years would adequately serve as their archive strategy
The differences between optical media, Write-Once Read-Many (WORM) media, and Non-Erasable, Non-Rewriteable (NENR) storage options.
Why putting a [space heater] on your data center floor is a bad idea, driving up power and cooling costs for little business value to the enterprise once the unit is full of rarely accessed read-only data.
An overview of the [IBM Information Archive], an integrated stack of servers, storage and software that replaces previous offerings such as the IBM System Storage DR550 and the IBM Grid Medical Archive Solution (GMAS).
The marketing bundle known as the [Information Archive for Email, Files and eDiscovery] that combines the Information Archive storage appliance with Content Collectors for email and file systems, as well as eDiscovery tools, and implementation services for a solution that can support a small or medium size business, up to 1400 employees.
IBM Tivoli Storage Productivity Center v4.2 Overview and Update
Many of the concerns raised when I [presented v4.1 at this conference last year] were addressed this year in v4.2, including full performance statistics for IBM XIV storage system, storage resource agent support for HP-UX and Solaris, and a variety of other issues.
I presented this overview in stages:
"Productivity Center Basic Edition" that comes pre-installed on the IBM System Storage Productivity Center hardware console, that provides discover of devices, basic configuration, and a clever topology viewer of what is connected to what.
"Productivity Center for Disk" and "Productivity Center for Disk Midrange Edition (MRE)" that provides real-time and historical performance monitoring, asset and capacity reporting.
"Productivity Center for Replication" which supports monitoring, failover and failback for FlashCopy, Metro Mirror and Global Mirror on the SVC, Storwize V7000, DS8000, DS6000 and ESS 800.
"Productivity Center for Data" which supports reporting on files, file systems and databases on DAS, SAN and NAS attached storage from a Operating System viewpoint.
"Productivity Center Standard Edition" which includes all of the above except "Replication", and adds performance monitoring of SAN Fabric gear, and some very clever analytics to improver performance and problem determination.
One of the questions that came up was "How big does my company have to be to consider using Productivity Center?" which I answered as follows:
"If you are a small company, and the "IT Person" has responsibilities outside the IT, and managing the few pieces of kit is just part of his job, then consider just using the web-based GUI through a Firefox or similar browser. If you are a medium sized company with dedicated IT personnel, but mostly run by system admins or database admins that manage storage and networks on the side, you might want to consider the "Storage Control" plug-in for IBM Systems Director. But if you are larger shop, and there are employees with the title "Storage Administrator" and/or "SAN Administrator", then Tivoli Storage Productivity Center is for you."
Tivoli Storage Productivity Center has matured into a fine piece of software that truly can help medium and large sized data centers manage their storage and storage networking infrastructure.
I like speaking the first day of these events. Often people come in just to hear the keynote speakers, and stay the afternoon to hear a few break-out sessions before they leave Tuesday or Wednesday for other meetings.
Clod Barrera is an IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage. He predicts that by 2015, 10 percent of the servers and storage purchases, as well as 25 percent of the network gear purchases, will be related to Cloud deployments. Cloud Storage is expected to grow at a compound annual growth rate (CAGR) of 32 percent through 2015, compared to only 3.8 percent growth for non-Cloud storage.
Cloud Computing is allowing companies to rethink their IT infrastructure, and reinvent their business. Clod presented an interesting chart on the "Taxonomy" of storage in Cloud environments. On the left he had examples of Storage that was part of a Cloud Compute application. On the right he had storage that was accessed directly through protocols or APIs. Under each he had several examples for transactional data, stream data, backups and archives.
Clod feels the only difference between Private and Public clouds is a matter of ownership. In private clouds, these are owned by the company that uses them via their private Intranet network. Public clouds are owned by Cloud Service providers and are accessed over the public Internet. Clod presented IBM's strategy to deliver Cloud at five levels:
Private Cloud: on-site equipment, behind company firewall, managed by IT staff
Managed Private Cloud: on-site equipment, behind company firewall, managed by IBM or other Cloud Service provider
Hosted Private Cloud: dedicated, off-premises equipment, located and managed by IBM or other Cloud Service Provider, and access through VPN
Shared Cloud Services: shared, off-premises equipment, located at IBM or other Cloud Service Provider, managed by IBM or Cloud Service provider, and access through VPN. The facility is intended for enterprises only, on a contractual basis, and will be auditable for compliance to government regulations, etc.
Public Cloud: shared, off-premises equipment, located and managed by IBM or other Cloud Service provider, targeted to offer cloud compute and storage resources, with standardized platforms of operating systems and middleware, for individuals, small and medium sized businesses.
As with storage in traditional data center deployments, storage in clouds will be tiered, with Tier 0 being the fastest tier, to Tier 4 for "deep and cheap" archive storage. IBM SONAS is an example of Cloud-ready storage that can help make these tiers accessible through standard Ethernet protocols. Cloud Service providers will use metering and Service Level Agreements (SLAs) to offer different rates for different tiers of storage in the cloud.
Clod wrapped up his session explaining IBM's Cloud Computing Reference Architecture (CCRA). This is an all-encompassing diagram that shows how all of IBM's hardware, software and services fit into Cloud deployments.
Since the [IBM System Storage Technical University 2011] runs concurrently with the System x Technical University, attendees are allowed to mix-and-match. I attended several presentations regarding server virtualization and hypervisors.
Matt Archibald is an IT Management Consultant in IBM's Systems Agenda Delivery team. He started with a history of hypervisors, from IBM's early CP/CMS in 1967, through the latest VMware Vsphere 5 just announced.
He explained that there are three types of Hypervisor architectures today:
Type 1 - often referred to as "Bare Metal" runs directly on the server host hardware, and allows different operating system virtual machines to run as guests. IBM's System z [PR/SM] and [PowerVM] as well as the popular VMware ESXi are examples of this type.
Type 2 - often referred to as "Hosted" runs above an existing operating system, and allows different operating system virtual machines to run as guests. The popular [Oracle/Sun VirtualBox] is an example of this type.
OS Containers - runs above an existing operating system base, and allows multiple "guests" that all run the same operating system as the base. This affords some isolation between applications. [Parallels Virtuozzo Containers] is an example of this type.
The dominant architecture is Type 1. For x86, IBM is the number one reseller of VMware. VMware recently announced [Vsphere 5], which changes its licensing model from CPU-based to memory-based. For example, a virtual machine with 32 virtual CPUs and 1TB of virtual RAM (VRAM) would cost over $73,000 per year to license the VMware "Enterprise Plus" software. The only plus-side to this new licensing is that the "memory" entitlement transfers during Disaster Recovery to the remote location.
"Xen is dead." was the way Matt introduced the section discussing Hybrid Type-1 hypervisors like Xen and Hyper-V. These run bare-metal, but require networking and storage I/O to be processed by a single bottleneck partition referred to as "Dom 0". As such, this hybrid approach does not scale well on larger multi-sock host servers. So, his Xen-is-dead message was referring to all Hybrid-based Hypervisors including Hyper-V, not just those based on Xen itself.
The new up-and-comer is "Linux KVM". Last year, in my blog post about [System x KVM solutions], I mentioned the confusion over KVM acronym used with two different meanings. Many people use KVM to refer to Keyboard-Video-Mouse switches that allow access to multiple machines. IBM has renamed these switches to Local Console Managers (LCM) and Global Console Manager (GCM). This year, the System x team have adopted the use of "Linux KVM" to refer to the second meaning, the [Kernel-based Virtual Machine] hypervisor.
Linux KVM is not a product, but an open-source project. As such, it is built into every Linux kernel. Red Hat has created two specific deliverables under the name Red Hat Enterprise Virtualization (RHEV):
RHEV-H, a tiny ESXi-like bare-metal hypervisor that fits in 78MB, making it small enough to be on a USB stick, CD-rom or memory chip.
RHEV-M, a vCenter-like management software to manage multiple virtual machines across multiple hosts.
Personally, I run RHEL 6.1 with KVM on my IBM laptop as my primary operating system, with a Windows XP guest image to run a few Windows-specific applications.
A complaint of the current RHEV 2.2 release from Linux fanboys is that RHEV-M requires a Windows server, and uses Windows Powershell for scripting. The next release of RHEV is likely to provide a Linux-based option for management server.
Of the various hypervisors evaluated, KVM appears to be poised to offer the best scalability for multi-socket host machines. The next release is expected to support up to 4096 threads, 64TB of RAM, and over 2000 virtual machines. Compare that to VMware Vsphere 5 that supports only 160 threads, 2TB of RAM and up to 512 virtual machines.
Linux KVM Overview
Matt also presented a session focused on Linux KVM. While IBM is the leading reseller of VMware for the x86 server platform, it has chosen Linux KVM to run all of its internal x86 Cloud Computing facilities, as it can offer 40 to 80 percent savings, based on Total Cost of Ownership (TCO).
Linux KVM can run unmodified Windows and Linux guest operating systems as guest images with less than 5 percent overhead. Since KVM is built into the Linux kernel, any certification testing automatically benefits KVM as well. KVM takes advantage of modern CPU extensions like Intel's VT and AMD's AMD-V.
For high availability, in the event that a host fails, KVM can restart the guest images on other KVM hosts. RHEV offers "prioritized restart order" which allows mision-critical images to be started before less important ones.
RHEV also provides "Virtual Desktop Infrastructure", known as VDI. This allows a lightweight client with a browser to access an OS image running on a KVM host. Matt was able to demonstrate this with Firefox browser running on his Android-based Nexus One smartphone.
RHEV also adds features that make it ideal for cloud deployments, including hot-pluggable CPU, network and storage; service Level Agreement monitoring for CPU, memory and I/O resources; storage live migrations to move the raw image files while guests are running; and a self-service user portal.
IBM has been doing server virtualization for decades. When I first started at IBM in 1986, I was doing z/OS development and testing on z/VM guest images. Later, around 1999, I started working with the "Linux on z" team, running multiple Linux images under PR/SM and z/VM. While the server virtualization solutions most people are familiar with (VMware, Hyper-V, Xen) have only been around the last five years or so, IBM has a much deeper and robust understanding and long heritage. This helps to set IBM apart from the competition when helping clients.
I gotten several emails expressing worry that I have fallen off the face of th earth. The last two weeks have been educational and eye-opening for me. I can't provide details in my blog, so I will just say that it involved government agencies that IBM refers to as "dark accounts", and that I am now back safely in the USA. Between adjusting to time zone differences, ridiculously long hours, and restricted access to the internet, I was unable to blog lately.
Instead, I will resume my coverage of the [IBM System Storage Technical University 2011]. The "Solutions Expo" runs Monday evening through Wednesday lunch. This is a chance for people to explore all the solutions that are part of IBM's large "eco-system" for IBM System storage and System x products. There were several sponsors for this event.
As is often the case at these conferences, the various booths hand out fun items. The hot items this year were tie-dyed tee-shirts from Qlogic, and propeller beanies from the IBM rack and power systems team. Here is Amanda, one of the bartenders showing off the latter.
After the expo on Tuesday night, my friends at [Texas Memory Systems] held an after-party. Unlike the pens, tee-shirts and keychains at the Expo, these guys had a raffle for real storage products. Here is Erik Eyberg handing out a RamSan PCIe card, valued at $14,000 or so. IBM recently certified the TMS RamSan as External SSD storage for the IBM SAN Volume Controller (SVC). The SVC can optimize performance using this for automated sub-LUN tiering with the IBM System Storage Easy Tier feature.
I always try to catch a session from Jim Blue, who works in our "SAN Central" center of competency team. This session was a long list of useful hints and tips, based on his many years of experience helping clients.
SAN Zoning works by inclusion, limiting the impact of failing devices. The best approach is to zone by individual initiator port. The default policy for your SAN zoning should be "deny".
Ports should be named to identify who, what, where and how.
While many people know not to mix both disk and tape devices on the same HBA, Jim also recommends not mixing dissimilar disks, test and production, FCP and FICON.
The sweet spot is FOUR paths. Too many paths can impact performance.
When making changes to redundant fabrics, make changes to the first fabric, then allow sufficient time before making the same changes to the other fabric.
Use software tools like Tivoli Storage Productivity Center (Standard Edition) to validate all changes to your SAN fabric.
Do not mix 62.5 and 50.0 micron technology.
Use port caps to disable inactive ports. In one amusing anecdote, he mention that an uncovered port was hit by sunlight every day, sending error messages that took a while to figure out.
Save your SAN configuration to non-SAN storage for backup
Consider firmware about two months old to be stable
Rule of thumb for estimating IOPS: 75-100 IOPS per 7200 RPM drive, 120-150 IOPS per 10K RPM drive, and 150-200 IOPS per 15K RPM drive.
Decide whether your shop is just-in-time or just-in-case provisioning. Just-in-time gets additional capacity on demand as needed, and just-in-case over-provisions to avoid scrambling last minute.
Avoid oversubscribing your inter-switch links (ISL). Aim for around 7:1 to 10:1 ratio.
Don't go cheap on bandwidth between sites for long-distance replication
Next Generation Network Fabrics - Strategy and Innovations
Mike Easterly, IBM Director of Global Field Marketing, presented IBM System Networking strategy, in light of IBM's recent acquisition of Blade Network Technologies (BNT). BNT is used in 350 of the Fortune 500 companies, and is ranked #2 behind Cisco in sales of non-core Ethernet switches (based on number of units sold).
Based on a recent survey, companies are upgrading their Ethernet networks for a variety of reasons:
56 percent for Live Partition Mobility and VMware Vmotion
45 percent for integrated compute stacks, like IBM CloudBurst
43 percent for private, public and hybrid cloud computing deployments
40 percent for network convergences
Many companies adopt a three-level approach, with core directors, distribution switches, and then access switches at the edge that connect servers and storage devices. IBM's BNT allows you to flatten the network to lower latency by collapsing the access and distribution levels into one.
IBM's strategy is to focus on BNT for the access/distribution level, and to continue its strategic partnerships for the core level.
IBM BNT provides better price/performance and lower energy consumption. To help with hot-aisle/cold-aisle rack deployments, IBM BNT provides both F and R models. F models have ports on the front, and R models have ports in the rear.
IBM BNT supports virtual fabric and HW-offload iSCSI traffic, and future-enabled for FCoE. Support for TRILL (transparent interconnect of lots of links) and OpenFlow will be implemented through software updates to the switches.
While Cisco Nexus 1000v is focused on VMware Enterprise Plus, IBM BNT's VMready works with VMware, Hyper-V, Linux KVM, XEN, OracleVM, and PowerVM. This allows single pane of management of VMready and ESX vSwitches.
In preparation for Converged Enhanced Ethernet (CEE), IBM BNT will provide full 40GbE support sometime next year, and offer switches that support 100GbE uplinks. IBM offers extended length cables, including passive SFP+ DAC at 8.5 meters, and 10Gbase-T Cat7 cables up to 100 meters.
Inter-datacenter Workload Mobility with VMware vSphere and SAN Volume Controller (SVC)
This session was co-presented between Bill Wiegand, IBM Advanced Technical Services, and Rawley Burbridge, IBM VMware and midrange storage consultant. IBM is the leader in storage virtualization product (SVC), and is the leading reseller of VMware.
Like MetroCluster on IBM N series, or EMC's VPLEX Metro, the IBM SAN Volume Controller can support a stretched cluster across distance that allows virtual machines to move seamlessly from one datacenter to another. This is a feature IBM introduced with SVC 5.1 back in 2009. This can be used for PowerVM Live Partition Mobility, VMware vMotion, and Hyper-V Quick Migration.
SVC stretched cluster can help with both Disaster Avoidance and Disaster Recovery. For Disaster Avoidance, in anticipation of an outage, VMs can be moved to the secondary datacenter. For Disaster Recover, additional automation, such as VMware High Availability (HA) is needed to restart the VMs at the secondary datacenter.
IBM stretched cluster is further improved with a feature called Volume Mirroring (formerly vDisk Mirroring) which creates two physical copies of one logical volume. To the VMware ESX hosts, there is only one volume, regardless of which datacenter it is in. The two physical copies can be on any kind of managed disk, as there is no requirement or dependency of copy services on the back-end storage arrays.
Another recent improvement is the idea of spreading the three quorum disks to three different locations or "failure domains". One in each data center, and a third one in a separate building, somewhere in between the other two, perhaps.
Of course, there are regional disasters that could affect both datacenters. For this reason, SVC stretched cluster volumes can be replicated to a third location up to 8000 km away. This can be done with any back-end disk arrays, as again there is not requirement for copy services from the managed devices. SVC takes care of it all.
Networking is going to be very important for a variety of transformational projects going forward in the next five years.
I have been working on Information Lifecycle Management (ILM) since before they coined the phrase. There were several break-out sessions on the third day at the [IBM System Storage Technical University 2011] related to new twists to ILM.
The Intelligent Storage Service Catalog (ISSC) and Smarter ILM
Hans Ammitzboll, Solution Rep for IBM Global Technology Services (GTS), presented an approach to ILM focused on using different storage products for different tiers. Is this new? Not at all! The original use of the phrase "Information Lifecycle Management" was coined in the early 1990s by StorageTek to help sell automated tape libraries.
Unfortunately, disk-only vendors started using the term ILM to refer to disk-to-disk tiering inside the disk array. Hans feels it does not make sense to put the least expensive penny-per-GB 7200 RPM disk inside the most expense enterprise-class high-end disk arrays.
IBM GTS manages not only IBM's internal operations, but the IT operations of hundreds of other clients. To help manage all this storage, they developed software to supplement reporting, monitoring and movement of data from one tier to another.
The Intelligent Storage Service Catalog (ISSC) can save up to 80 percent of planning time for managing storage. What did people use before? Hans poked fun at chargeback and showback systems that "offer savings" but don't actually "impose savings". He referred to these as Name-and-Shame, where the top 10 offenders of storage usage.
His storage pyramid involves a variety of devices, with IBM DS8000, SVC and XIV for the high-end, midrange disk like Storwize V7000, and blended disk-and-tape solutions like SONAS and Information Archive (IA) for the lower tiers.
Mark Taylor, IBM Advanced Technical Services, presented the policy-driven automation of IBM's Scale-Out NAS (SONAS). A SONAS system can hold 1 to 256 file systems, and each file system is further divided into fileset containers. Think of fileset containers like 'tree branches' of the file system.es.
SONAS supports policies for file placement, file movement, and file deletion. These are SQL-like statements that are then applied to specific file systems in the SONAS. Input variables include date last modified, date last accessed, file name, file size, fileset container name, user id and group id. You can choose to have the rules be case-sensitive or case-insensitive. The rules support macros. A macro pre-processor can help simplify calculations and other definitions that are used repeatedly.
Each file system in SONAS consists of one or more storage pools. For file systems with multiple pools, file placement policies can determine which pool to place each file. Normally, when a set of files are in a specific sub-directory on other NAS systems, all the files will be on the same type of disk. With SONAS, some files can be placed on 15K RPM drives, and other files on slower 7200 RPM drives. This file virtualization separates the logical grouping of files from the physical placement of them.
Once files are placed, other policies can be written to migrate from one disk pool to another, migrate from disk to tape, or delete the file. Migrating from one disk pool to another is done by relocation. The next time the file is accessed, it will be accessed directly from the new pool. When migrating from disk to tape, a stub is left in the directory structure metadata, so that subsequent access will cause the file to be recalled automatically from tape, back to disk. Policies can determine which storage pool files are recalled to when this happens.
Migrating from disk to tape involves sending the data from SONAS to external storage pool manager, such as IBM Tivoli Storage Manager (TSM) server connected to a tape library. SONAS supports pre-migration, which allows the data to be copied to tape, but left on disk, until space is needed to be freed up. For example, a policy with THRESHOLD(90,70,50) will kick in when the file system is 90 percent full, file will be migrated (moved) to tape until it reaches 70 percent, and then files will be pre-migrated (copied) to tape until it reaches 50 percent.
Policies to delete files can apply to both disk and tape pools. Files deleted on tape remove the stub from the directory structure metadata and notify the external storage pool manager to clean up its records for the tape data.
If this all sounds like a radically new way of managing data, it isn't. Many of these functions are based on IBM's Data Facility Storage Management Subsystem (DFSMS) for the mainframe. In effect, SONAS brings mainframe-class functionality to distributed systems.
Understanding IBM SONAS Use Cases
For many, the concept of a scale-out NAS is new. Stephen Edel, IBM SONAS product offering manager, presented a variety of use cases where SONAS has been successful.
First, let's consider backup. IBM SONAS has built-in support for Tivoli Storage Manager (TSM), as well as supporting the NDMP industry standard protocol, for use with Symantec NetBackup, Commvault Simpana, and EMC Legato Networker. While many NAS solutions support NDMP, IBM SONAS can support up to 128 session per interface node, and up to 30 interface nodes, for parallel processing. SONAS has a high-speed file scan to identify files to be backed up, and will pre-fetch the small files into cache to speed up the backup process. A SONAS system can support up to 256 systems, and each file system can be backed up on its own unique schedule if you like. Different file systems can be backed up to different backup servers.
SONAS also has anti-virus support, with your choice of Symantec or McAfee. An anti-virus scan can be run on demand, as needed, or as files are individually accessed. When a Windows client reads a file, SONAS will determine if it has been already scanned with the most recent anti-virus signatures, and if not, will scan before allowing the file to be read. SONAS will also scan new files created.
Successful SONAS deployments addressed the following workloads:
content capture including video capture
high performance computing, research and business analytics
"Cheap and Deep" archive
worldwide information exchange and geographically distant collaboration
SONAS is selling well in Government, Universities, Healthcare, and Media/Entertainment, but is not limited to these industries. It can be used for private cloud deployments and public cloud deployments. Having centralized management for Petabytes of data can be cost-effective either way.
IBM SONAS brings the latest techologies to bring a Smarter ILM to a variety of workloads and use cases.
IBM Storage Strategy for the Smarter Computing Era
I presented this session on Thursday morning. It is a session I give frequently at the IBM Tucson Executive Briefing Center (EBC). IBM launched [Smarter Computing initiative at IBM Pulse conference]. My presentation covered the role of storage in Business Analytics, Workload Optimized Systems, and Cloud Computing.
Layer 8: Cloud Computing and the new IT Delivery Model
Ed Batewell, IBM Field Technical Support Specialist, presented this overview on Cloud Computing. The "Layer 8" is a subtle reference to the [7-layer OSI Model] for networking protocols. Ed cites insights from the [2011 IBM Global CIO Survey]. Of the 3000 companies surveyed, 60 percent plan to use or deploy clouds. In USA, 70 percent of CIOs have significant plans for cloud within the next 3-5 years. These numbers are double the statistics gleamed from the 2009 Global CIO survey. Clouds are one of IBM's big four initiatives, expecting to generate $7 Billion USD annual revenues by 2015.
IBM is recognized in the industry as one of "Big 5" vendors (Google, Yahoo, Microsoft, and Amazon round out the rest). As such, IBM has contributed to the industry a set of best practices known as the [Cloud Computing Reference Architect (36-page document)]. As is typical for IBM, this architecture is end-to-end complete, covering the three main participants for successful cloud deployments:
Consumers: the people and systems that use cloud computing services
Providers: the people, infrastructure and business operations needed to deliver IT services to consumers
Developers: the people and their development tools that create apps and platforms for cloud computing
IBM is working hard to eliminate all barriers to adoption for Cloud Computing. [Mirage image management] can patch VM images offline to address "Day 0" viruses. [Hybrid Cloud Integrator can help integrate new Cloud technologies to legacy applications. [IBM Systems Director VMcontrol] can manage VM images from z/VM on the mainframe, to PowerVM on UNIX servers, to VMware, Microsoft, Xen and KVM for x86 servers. IBM's [Cloud Service Provider Platform (CSP2)] is designed for Telecoms to offer Cloud Computing services. IBM CloudBurst is a "Cloud-in-a-Can" optimized stack of servers, storage and switches that can be installed in five days and comes in various "tee-shirt sizes" (Small, Medium, Large and Extra Large), depending on how many VMs you want to run.
Ed mentioned that companies trying to build their own traditional IT applications and environments, in an effort to compete against the cost-effective Clouds, reminded him of Thomas Thwaites' project of building a toaster from scratch. You can watch the [TED video, 11 minutes]:
An interesting project is [Reservoir] which IBM is working with other industry leaders to develop a way to seamlessly migrate VMs from one location to another, globally, without requiring shared storage, SAN zones or Ethernet subnets. This is similar to how energy companies buy and sell electricity to each other, as needed, or the way telecommunications companies allow roaming acorss each others networks.
IBM System Networking - Convergence
Jeff Currier, IBM Executive Consultant for the new IBM System Networking group, presented this session on Network Convergence. Storage is expected to grow 44x, from 0.8 [Zettabytes] in 2009, to 35 Zetabytes by the year 2020. The role of the network is growing in importance. IBM refers to this converged loss-less Ethernet network as "Convergence Enhanced Ethernet" (CEE), which Cisco uses the term "Data Center Ethernet" (DCE), and the rest of the industry uses "Data Center Bridging" (DCB).
To make this happen, we need to replace Spanning Tree Protocol [STP] that eliminates walking in circles in a multi-hop network configuration, with a new Layer 2 Multipathing (L2MP) protocol. The two competing for the title are Shortest Path Bridging (IEEE 802.1aq) and Transparent Interconnect of Lots of Links (IETF TRILL).
All roads lead to Ethernet. While FCoE has not caught on as fast as everyone hoped, iSCSI has benefited from all the enhancements to the Ethernet standard. iSCSI works in both lossy and lossless versions of Ethernet, and seems to be the preferred choice for new greenfield deployments for Small and Medium sized Businesses (SMB). Larger enterprises continue to use Fibre Channel (FCP and FICON), but might use single-hop FCoE from the servers to top-of-rack switches. Both iSCSI and FCoE scale well, but FCoE is considered more efficient.
IBM has a strategy, and is investing heavily in these standards, technologies, and core competencies.
Continuing my coverage of the [IBM System Storage Technical University 2011], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This year, we had two, one for System x called "Ask the eXperts", and one for System Storage called "Storage Free-for-All". This post covers the latter.
(Disclaimer: Do not shoot the messenger! We had a dozen or more experts on the panel, representing System Storage hardware, Tivoli Storage software, and Storage services. I took notes, trying to capture the essence of the questions, and the answers given by the various IBM experts. I have spelled out acronyms and provided links to relevant materials. The answers from individual IBMers may not reflect the official position of IBM management. Where appropriate, my own commentary will be in italics.)
You are in the wrong session! Go to "Ask the eXperts" session next door!
The TSM GUI sucks! Are there any plans to improve it?
Yes, we are aware that products like IBM XIV have raised the bar for what people expect from graphical user interfaces. We have plans to improve the TSM GUI. IBM's new GUI for the SAN Volume Controller and Storwize V7000 has been well-received, and will be used as a template for the GUIs of other storage hardware and software products. The GUI uses the latest HTML5, Dojo widgets and AJAX technologies, eliminating Java dependencies on the client browser.
Can we run the TSM Admin GUI from a non-Windows host?
IBM has plans to offer this. Most likely, this will be browser-based, so that any OS with a modern browser can be used.
As hard disk drives grow larger in capacity, RAID-5 becomes less viable. What is IBM doing to address this?
IBM is aware of this problem. IBM offers RAID-DP on the IBM N series, RAID-X on the IBM XIV, and RAID-6 on its other disk systems.
TPC licensing is outrageous! What is IBM going to do about it?
About 25 percent of DS8000 disk systems have SSD installed. Now that IBM DS8000 Easy Tier supports "any two" tiers, roughly 50 percent of DS8000 now have Easy Tier activated. No idea on how Easy Tier has been adopted on SVC or Storwize V7000.
We have an 8-node SVC cluster, should we put 8 SSD drives into a single node-pair, or spread them out?
We recommend putting a separate Solid-State Drive in each SVC node, with RAID-1 between nodes of a node-pair. By separating the SSD across I/O groups, you can reduce node-to-node traffic.
How well has SVC 6.2 been adopted?
The inventory call-home data is not yet available. The only SVC hardware model that does not support this level of software was the 2145-4F2 introduced in 2003. Every other model since then can be updated to this level.
Will IBM offer 600GB FDE drives for the IBM DS8700?
Currently, IBM offers 300GB and 450GB 15K RPM drives with the Full-Disk Encryption (FDE) capability for the DS8700, and 450GB and 600GB 10K RPM drives with FDE for the IBM DS8800. IBM is working with its disk suppliers to offer FDE on other disk capacities, and on SSD and NL-SAS drives as well, so that all can be used with IBM Easy Tier.
Is there a reason for the feature lag between the Easy Tier capabilities of the DS8000, and that of the SVC/Storwize V7000?
We have one team for Easy Tier, so they implement it first on DS8000, then port it over to SVC/Storwize V7000.
Does it even make sense to have separate storage tiers, especially when you factor in the cost of SVC and TPC to make it manageable?
It depends! We understand this is a trade-off between cost and complexity. Most data centers have three or more storage tiers already, so products like SVC can help simplify interoperability.
Are there best practices for combining SVC with DS8000? Can we share one DS8000 system across two or more SVC clusters?
Yes, you can share one DS8000 across multiple SVC clusters. DS8000 has auto-restripe, so consider having two big extent pools. The queue depth is 3 to 60, so aim to have up to 60 managed disks on your DS8000 assigned to SVC. The more managed disks the better.
The IBM System Storage Interopability Center (SSIC) site does not seem to be designed well for SAN Volume Controller.
Yes, we are aware of that. It was designed based on traditional Hardware Compatability Lists (HCL), but storage virtualization presents unique challenges.
How does the 24-hour learning period work for IBM Easy Tier? We have batch processing that runs from 2am to 8am on Sundays.
You can have Easy Tier monitor across this batch job window, and turn Easy Tier management between tiers on and off as needed.
Now that NetApp has acquired LSI, is the DS3000 still viable?
Yes, IBM has a strong OEM relationship with both NetApp and LSI, and this continues after the acquisition.
If have managed disks from a DS8000 multi-rank extent pool assigned to multiple SVC clusters, won't this affect performance?
Yes, possibly. Keep managed disks on seperate extent pools if this is a big concern. A PERL script is available to re-balance SVC striped volumes as needed after these changes.
Is the IBM [TPC Reporter] a replacement for IBM Tivoli Storage Productivity Center?
No, it is software, available at no additional charge, that provides additional reporting to those who have already licensed Tivoli Storage Productivity Center 4.1 and above. It will be updated as needed when new versions of Productivity Center are released.
We are experiencing lots of stability issues with SDD, SDD-PCM and SDD-DSM multipathing drivers. Are these getting the development attention they deserve?
IBM's direction is to shift toward native OS-based multipathing drivers.
Is anyone actually thinking of deploying public cloud storage in the near-term?
A few hands in the audience were raised.
None of the IBM storage devices seem to have [REST API]. Cloud storage providers are demanding this. What are IBM plans?
IBM plans to offer REST on SONAS. IBM uses SONAS internally for its own cloud storage offerings.
If you ask a DB2 specialist, an AIX specialist, and a System Storage specialist, on how to configure System p and System Storage for optimal performance, you get three different answers. Are there any IBMers who are cross-functional that can help?
Yes, for example, Earl Jew is an IBM Field Technical Support Specialist (FTSS) for both System p and Storage, and can help you with that.
Both Oracle and Microsoft recommend RAID-10 for their applications.
Don't listen to them. Feel free to use RAID-5, RAID-6 or RAID-X instead.
Resizing SVC source volumes forces ongoing FlashCopy or Metro Mirror relatiohships to be stopped. Does IBM plan to address this?
Currently, you have to stop, resize both source and target, then start the relationship again. Consider getting IBM Tivoli Storage Productivity Center for Replication (TPC-R).
IBM continues to support this for exising clients. For new deployments, IBM offers SONAS and the Information Archive (IA).
When will I be able to move SVC volumes between I/O groups?
You can today, but it is disruptive to the operating system. IBM is investigating making this less disruptive.
Will XIV ever support the mainframe?
It does already, with support for both Linux and z/VM today. For VSE support, use SVC with XIV. For those with the new zBX extension, XIV storage can be used with all of the POWER and x86-based operating systems supported. IBM has no plans to offer direct FICON attachment for z/OS or z/TPF.
Not a question - Kudos to the TSM and ProtecTIER team in supporting native IP-based replication!
When will IBM offer POWER-based models of the XIV, SVC and other storage devices?
IBM's decision to use industry-standard x86 technology has proven quite successful. However, IBM re-looks at this decision every so many years. Once again, the last iteration determined that it was not worth doing. A POWER-based model might not beat the price/performance of current x86 models, and maintaining two separate code bases would hinder development of new innovations.
We have both System i and System z, what is IBM doing to address the fact that PowerHA and GDPS are different?
IBM TPC-R has a service offering extension to support "IBM i" environments. GDPS plans to support multi-platform environments as well.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.
Wrapping up my coverage of the [IBM System Storage Technical University 2011], I attended a few sessions on Friday morning. The last session was Glenn Anderson's "IT Game Changers: the IT Professional's Guide to Becoming a Technology Trailblazer." Glenn used to run the Storage University events, but now is the conference manager for the System z mainframe events.
Glenn organized this talk from lessons from the following books:
Glen suggested that IT professionals should understand the dissatisfaction with IT that is driving companies to switch over to Cloud Computing. IT professionals should adopt a service-oriented approach, realize the full potential of new disruptive technologies, and know when to "jump the curve" to the next generation of technology. For example, IT professionals should lead the movement to Cloud. If you build your own private cloud, or purchase some time for instances on a public cloud, you will be in a better position to be the "trusted advisor" to IT management.
CIOs should encourage IT to be part of the corporate strategy, but may have to fix the broken IT funding model. The IT department should be a "value center" not a "cost center" as it has been traditionally treated. When treated as a "cost center", IT departments only focus on cost reductions, and not looking at ways that the IT department can help drive revenues, improve customer service, or enhance employee productivity. A well-orgnized IT department can be a competitive advantage.
Taking a "service-oriented" approach allows IT and Business Process to come together. Often times, IT and business professionals don't communicate well, and this new service-oriented approach can bridge the gap. Service Oriented Architecture [SOA] can help connect existing legacy applications to the new Cloud Computing environment.
IT budgets should consist of two parts. Strategic funding for new IT projects, and an operational budget for keeping current applications running. Roughly 45 percent of capital investment in USA goes toward IT. Too often, the IT department is focused on itself, on technology and reducing costs, and not enough on aligning IT with business transformation. When IT is used in conjunction with a sound business strategy, their can be significant payoff.
After 550 years, the printing press and printed materials are being pushed from center. While other electronic media like radio and television have been around for a while, the internet and digital publishing are constantly available, and represent a shift from traditional printed materials.
When evaluating new technologies, IT professionals should ask themselves a few questions. Is it easy to use? Does it enable people to connect in new ways? Is it more cost-effective, or tap new sources of revenue? Does it shift power from one player to another? A new intellectual ethic is taking hold. Becoming an IT Game Changer can help stay one step ahead as Cloud Computing and other new IT platforms are adopted.
This week, July 26-30, 2010, I am in Washington DC for the annual [2010 System Storage Technical University]. As with last year, we have joined forces with the System x team. Since we are in Washington DC this time, IBM added a "Federal Track" to focus on government challenges and solutions. So, basically, offering attendees the option to attend three conferences for one low price.
This conference was previously called the "Symposium", but IBM changed the name to "Technical University" to emphasize the technical nature of the conference. No marketing puffery like "Journey to the Private Cloud" here! Instead, this is bona fide technical training, qualifying attendees to count this towards their Continuing Professional Education (CPE).
(Note to my readers:The blogosphere is like a playground. In the center are four-year-olds throwing sand into each other's faces, while mature adults sit on benches watching the action, and only jumping in as needed. For example, fellow blogger Chuck Hollis (EMC) got sand in his face for promising to resign if EMC ever offered a tacky storage guarantee, and then [failed to follow through on his promise] when it happened.
Several of my readers asked me to respond to another EMC blogger's latest [fistful of sand].
A few months ago, fellow blogger Barry Burke (EMC) committed to [stick to facts] in posts on his Storage Anarchist blog. That didn't last long! BarryB apparently has fallen in line with EMC's over-promise-then-under-deliver approach. Unfortunately, I will be busy covering the conference and IBM's robust portfolio of offerings, so won't have time to address BarryB's stinking pile of rumor and hearsay until next week or later. I am sorry to disappoint.)
This conference is designed to help IT professionals make their business and IT infrastructure more dynamic and, in the process, help reduce costs, mitigate risks, and improve service. This technical conference event is geared to IT and Business Managers, Data Center Managers, Project Managers, System Programmers, Server and Storage Administrators, Database Administrators, Business Continuity and Capacity Planners, IBM Business Partners and other IT Professionals. This week will offer over 300 different sessions and hands-on labs, certification exams, and a Solutions Center.
For those who want a quick stroll through memory lane, here are my posts from past events:
In keeping up with IBM's leadership in Social Media, IBM Systems Lab Services and Training team running this event have their own [Facebook Fan Page] and
[blog]. IBM Technical University has a Twitter account [@ibmtechconfs], and hashtag #ibmtechu. You can also follow me on Twitter [@az990tony].
Continuing my week in Washington DC for the annual [2010 System Storage Technical University], here is my quick recap of the keynote sessions presented Monday morning. Marlin Maddy, Worldwide Technical Events Executive for IBM Systems Lab Services and Training, served as emcee.
Roland Hagan, IBM Vice President for IBM System x server platform, presented on how IBM is redefining the x86 computing experience. More than 50 percent of all servers are x86 based. These x86 servers are easy to acquire, enjoy a large application base, and can take advantage of readily available skilled workforce for administration. The problem is that 85 percent of x86 processing power remains idle, energy costs are 8 times what they were 12 years ago, and management costs are now 70 percent of the IT budget.
IBM has the number one market share for scalable x86 servers. Roland covered the newly announced eX5 architecture that has been deployed in both rack-optimized models as well as IBM BladeCenter blade servers. These can offer 2x the memory capacity as competitive offerings, which is important for today's server virtualization, database and analytics workloads. This includes 40 and 80 DIMM models of blades, and 64 to 96 DIMM models of rack-optimized systems. IBM also announced eXFlash, internal Solid State Drives accessible at bus speeds. FlexNode allows a 4-node system to dynamically change to 2 separate 2-node systems.
By 2013, analysts estimate that 69 percent of x86 workloads will be virtualized, and that 22 percent of servers will be running some form of hypervisor software. By 2015, this grows to 78 percent of x86 workloads being virtualized, and 29 percent of servers running hypervisor.
Doug Balog, IBM Vice President and Disk Storage Business Line Executive, presented how the growth of information results in a "perfect storom" for the storage industry. Storage Admins are focused on managing storage growth and the related costs and complexity, proper forecasting and capacity planning, and backup administration. IBM's strategy is to help clients in the following areas:
Storage Efficiency - getting the most use out of the resources you invest
Service Delivery - ensuring that information gets to the right people at the right time, simplify reporting and provisioning
Data Protection - protecting data against unethical tampering, unauthorized access, and unexpected loss and corruption
He wrapped up his talk covering the success of DS8700 and XIV. In fact, 60 percent of XIV sales are to EMC customers. The TCO of an XIV is less than half the TCO of a comparable EMC VMAX disk system.
Dave McQueeney, IBM Vice President for Strategy and CTO for US Federal, covered how IBM's Smarter Planet vision for smarter cities, smarter healthcare, smarter energy grid and smarter traffic are being adopted by the public sector. Almost every data center in US Federal government is out of power, floor space and/or cooling capability. An estimated 80 percent of US Federal government IT budgets are spent on maintenance and ongoing operations, leaving very little left over for the big transformational projects that President Barack Obama wants to accomplish.
Who has the most active Online Transaction Processing (OLTP)? You might guess a big bank, but it is the US Department of Homeland Security (DHS), with a system processing 600 million transactions per day. Another government agency is #2, and the top Banking application is finally #3. The IBM mainframe has solved problems 10 to 15 years ago that the distributed systems are just now encountering today. Worldwide, more than 80 percent of banks use mainframes to handle their financial transactions.
IBM's recent POWER7 set of servers are proving successful in the field. For example, Allianz was able to consolidate 60 servers to 1. Running DB2 on POWER7 server is 38 percent less expensive than Oracle on x86 Nehalem processors. For Java, running JVM on POWER7 is 73 percent better than JVM on x86 Nehalem.
The US federal government ingests a large amount of data. It has huge 10-20 PB data warehouses. In fact, the amount of GB received every year by the US federal government alone exceed the production of all disk drives produced by all drive manufacturers. This means that all data must be processed through "data reduction" or it is gone forever.
The last keynote for Monday was given by Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist for System Storage. He started out shocking the audience with his view that the "disk drive industry is a train wreck". While R&D in disk drives enjoyed a healthy improvement curve up to about 2004, it has now slowed down, getting more difficult and more expensive to improve performance and capacity of disk drives. The rest of his presentation was organized around three themes:
Integrated Stacks - while new-comers like Oralce/Sun and the VCE coalition are promoting the benefits of integrated stacks, IBM has been doing this for the past five decades. New advancements in Server and Storage virtualization provide exciting new opportunities.
Integrated Systems - solutions like IBM Information Archive and SONAS, and new features like Easy Tier that help adopt SSD transparently. As it gets harder and harder to scale-up, IBM has moved to innovative scale-out architectures.
Integrated Data Center management - companies are now realizing that management and governance are critical factors of success, and that this needs to be integrated between traditional IT, private, public and hybrid cloud computing.
This was a great inspiring start for what looks like an awesome week!
Continuing my week in Washington DC for the annual [2010 System Storage Technical University], I presented a session on Storage for the Green Data Center, and attended a System x session on Greening the Data Center. Since they were related, I thought I would cover both in this post.
Storage for the Green Data Center
I presented this topic in four general categories:
Drivers and Metrics - I explained the three key drivers for consuming less energy, and the two key metrics: Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCiE).
Storage Technologies - I compared the four key storage media types: Solid State Drives (SSD), high-speed (15K RPM) FC and SAS hard disk, slower (7200 RPM) SATA disk, and tape. I had comparison slides that showed how IBM disk was more energy efficient than competition, for example DS8700 consumes less energy than EMC Symmetrix when compared with the exact same number and type of physical drives. Likewise, IBM LTO-5 and TS1130 tape drives consume less energy than comparable HP or Oracle/Sun tape drives.
Integrated Systems - IBM combines multiple storage tiers in a set of integrated systems managed by smart software. For example, the IBM DS8700 offers [Easy Tier] to offer smart data placement and movement across Solid-State drives and spinning disk. I also covered several blended disk-and-tape solutions, such as the Information Archive and SONAS.
Actions and Next Steps - I wrapped up the talk with actions that data center managers can take to help them be more energy efficient, from deploying the IBM Rear Door Heat Exchanger, or improving the management of their data.
Greening of the Data Center
Janet Beaver, IBM Senior Manager of Americas Group facilities for Infrastructure and Facilities, presented on IBM's success in becoming more energy efficient. The price of electricity has gone up 10 percent per year, and in some locations, 30 percent. For every 1 Watt used by IT equipment, there are an additional 27 Watts for power, cooling and other uses to keep the IT equipment comfortable. At IBM, data centers represent only 6 percent of total floor space, but 45 percent of all energy consumption. Janet covered two specific data centers, Boulder and Raleigh.
At Boulder, IBM keeps 48 hours reserve of gasoline (to generate electricity in case of outage from the power company) and 48 hours of chilled water. Many power outages are less than 10 minutes, which can easily be handled by the UPS systems. At least 25 percent of the Computer Room Air Conditioners (CRAC) are also on UPS as well, so that there is some cooling during those minutes, within the ASHRAE guidelines of 72-80 degrees Fahrenheit. Since gasoline gets stale, IBM runs the generators once a month, which serves as a monthly test of the system, and clears out the lines to make room for fresh fuel.
The IBM Boulder data center is the largest in the company: 300,000 square feet (the equivalent of five football fields)! Because of its location in Colorado, IBM enjoys "free cooling" using outside air temperature 63 percent of the year, resulting in a PUE of 1.3 rating. Electricity is only 4.5 US cents per kWh. The center also uses 1 Million KwH per year of wind energy.
The Raleigh data center is only 100,000 Square feet, with a PUE 1.4 rating. The Raleigh area enjoys 44 percent "free cooling" and electricity costs at 5.7 US cents per kWh. The Leadership in Energy and Environmental Design [LEED] has been updated to certify data centers. The IBM Boulder data center has achieved LEED Silver certification, and IBM Raleigh data center has LEED Gold certification.
Free cooling, electricity costs, and disaster susceptibility are just three of the 25 criteria IBM uses to locate its data centers. In addition to the 7 data centers it manages for its own operations, and 5 data centers for web hosting, IBM manages over 400 data centers of other clients.
It seems that Green IT initiatives are more important to the storage-oriented attendees than the x86-oriented folks. I suspect that is because many System x servers are deployed in small and medium businesses that do not have data centers, per se.
Continuing my week in Washington DC for the annual [2010 System Storage Technical University], here is my quick recap of the keynote sessions presented Monday morning. Marlin Maddy, Worldwide Technical Events Executive for IBM Systems Lab Services and Training, served as emcee.
Jim Northington, IBM System x Business Line Executive, covered the IT industry's "Love/Hate Relationship" with x86 platform. Many of the physical limitations that were previously a pain on this platform are now addressed, through a combination of IBM's new innovative eX5 architecture and virtualization technologies.
Jim also presented the [IBM CloudBurst] solution. IBM CloudBurst is one of the many "Integrated Systems" designed to help simplify deployment. Based on IBM BladeCenter, the IBM CloudBurst is basically a Private Cloud rack for those that are ready to deploy in their own data center.
Jim feels that server virtualization on x86 platforms is still in its infancy. IBM calls it the 70/30 rule: 70 percent of x86 workloads are running virtualized on 30 percent of the physical servers.
Maria Azua, IBM Vice President of Cloud Computing Enablement, presented on Cloud Computing. Technology is being adopted at faster rates. It took 40 years for radio to get 60 million listeners, 20 years for 60 million television viewers, 3 years to get 60 million surfers on the Internet, but it only took 4 months to get 60 million players on Farmville!
Maria covered various aspects of Cloud Computing: virtualization images, service catalog, provisioning elasticity, management and billing services, and virtual networks. With Cloud Computing, the combination of virtualization technologies, standardization, and automation can reduce costs and improve flexibility.
We've seen this happen before. Telcos transitioned from human operators to automated digital switches. Manufacturers went from having small teams of craftsmen to assembly lines of robots. Banks went from long lines of bank tellers to short lines at the ATM.
Maria said that companies are faced with three practical choices:
Do-it-Yourself, buy the servers, storage and switches and connect everything together.
Purchase pre-installed "integrated systems" to simplify deployment.
Subscribe to Cloud computing, allowing a service provider do all this for you.
In countries where network access is not ubiquitous, IBM has developed tools for the cloud that work in "offline" mode. IBM has also developed or modified tools to run better in the cloud. Launching a computer instance from the cloud from the service catalog is so easy to do, your 5-year-old child can do this!
Want to see Cloud Computing in action? Check out [Innovation.ed.gov], which is run in the IBM cloud, for the US Department of Education's website to foster innovation.
Whether you adopt public, private or a hybrid cloud computing approach, Maria suggests you take time to plan, test your applications for standardization, examine all risks, and explore new workloads that might be good candidates. Otherwise, moving to the cloud might just mean "More mess for less". Maria provided a list of applications that IBM considers good fit for Cloud Computing today.
I heard several audience members indicate that this is the first time someone finally explained Cloud Computing to them in a way that made sense!
IBM Tivoli Storage Productivity Center version 4.1 Overview
In conferences like these, there are two types of product-level presentations. An "Overview" explains how products work today to those who are not familiar with it. An "Update" explains what's new in this version of the product for those who are already familiar with previous releases. This session was an Overview of [Tivoli Storage Productivity Center], plus some information of IBM's Storage Enterprise Resource Planner [SERP] from IBM's acquisition of NovusCG.
I was one of the original lead architects of Productivity Center many years ago, and was able to share many personal experiences about its evolution in development and in the field at client facilities. Analysts have repeatedly rated IBM Productivity Center as one of the top Storage Resource Management (SRM) tools available in the marketplace.
I would like to thank my colleague Harley Puckett for his assistance in putting the finishing touches on this presentation. This was my best attended session of the week, indicating there is a lot of interest in this product in particular, and managing a heterogeneous mix of storage devices in general. To hear a quick video introduction, see Harley Puckett's presentation at the [IBM Virtual Briefing Center].
Information Lifecycle Management (ILM) Overview
Can you believe I have been doing ILM since 1986? I was the lead architect for DFSMS which provides ILM support for z/OS mainframes. In 2003-2005, I spent 18 months in the field performing ILM assessments for clients, and now there are dozens of IBM practitioners in Global Services and Lab Services that do this full time. This is a topic I cover frequently at the IBM Executive Briefing Center [EBC], because it addresses several top business challenges:
Reducing costs and simplifying management
Improving efficiency of personnel and application workloads
Managing risks and regulatory compliance
IBM has a solution based on five "entry points". The advantage of this approach is that it allows our consultants to craft the right solution to meet the specific requirements of each client situation. These entry points are:
Tiered Information Infrastructure - we don't limit ourselves to just "Tiered Storage" as storage is only part of a complete[information infrastructure] of servers,networks and storage
Storage Optimization and Virtualization - including virtual disk, virtual tape and virtual file solutions
Process Enhancement and Automation - an important part of ILM are the policies and procedures, such as IT Infrastructure Library [ITIL] best practices
Archive and Retention - space management and data retention solutions for email, database and file systems
When I presented ILM last year, I did not get many attendees. This time I had more, perhaps because of the recent announcement of ILM and HSM support in IBM SONAS and our April announcement of IBM DS8700 Easy Tier has renewed interest in this area.
I have safely returned back to Tucson, but have still a lot of notes of the other sessions I attended, so will cover them this week.
Continuing coverage of my week in Washington DC for the annual [2010 System Storage Technical University], I attended several XIV sessions throughout the week. There were many XIV sessions. I could not attend all of them. Jack Arnold, one of my colleagues at the IBM Tucson Executive Briefing Center, often presents XIV to clients and Business Partners. He covered all the basics of XIV architecture, configuration, and features like snapshots and migration. Carlos Lizarralde presented "Solving VMware Challenges with XIV". Ola Mayer presented "XIV Active Data Migration and Disaster Recovery".
Here is my quick recap of two in particular that I attended:
XIV Client Success Stories - Randy Arseneau
Randy reported that IBM had its best quarter ever for the XIV, reflecting an unexpected surge shortly after my blog post debunking the DDF myth last April. He presented successful case studies of client deployments. Many followed a familiar pattern. First, the client would only purchase one or two XIV units. Second, the client would beat the crap out of them, putting all kinds of stress from different workloads. Third, the client would discover that the XIV is really as amazing as IBM and IBM Business Partners have told them. Finally, in the fourth phase, the client would deploy the XIV for mission-critical production applications.
A large US bank holding company managed to get 5.3 GB/sec from a pair of XIV boxes for their analytics environment. They now have 14 XIV boxes deployed in mission-critical applications.
A large equipment manufacturer compared the offerings among seven different storage vendors, and IBM XIV came out the winner. They now have 11 XIV boxes in production and another four boxes for development/test. They have moved their entire VMware infrastructure to IBM XIV, running over 12,000 guest instances.
A financial services company bought their first XIV in early 2009 and now has 34 XIV units in production attached to a variety of Windows, Solaris, AIX, Linux servers and VMware hosts. Their entire Microsoft Exchange was moved from HP and EMC disk to IBM XIV, and experienced noticeable performance improvement.
When a University health system replaced two competitive disk systems with XIV, their data center temperature dropped from 74 to 68 degrees Fahrenheit. In general, XIV systems are 20 to 30 percent more energy efficient per usable TB than traditional disk systems.
A service provider that had used EMC disk systems for over 10 years evaluated the IBM XIV versus upgrading to EMC V-Max. The three year total cost of ownership (TCO) of EMC's V-Max was $7 Million US dollars higher, so EMC counter-proposed CLARiiON CX4 instead. But, in the end, IBM XIV proved to be the better fit, and now the customer is happy having made the switch.
The manager of an information communications technology service provider was impressed that the XIV was up and running in just a couple of days. They now have over two dozen XIV systems.
Another XIV client had lost all of their Computer Room Air Conditioning (CRAC) units for several hours. The data center heated up to 126 degrees Fahrenheit, but the customer did not lose any data on either of their two XIV boxes, which continued to run in these extreme conditions.
Optimizing XIV Performance - Brian Cormody
This session was an update from the [one presented last year] by Izhar Sharon. Brian presented various best practices for optimizing the performance when using specific application workloads with IBM XIV disk systems.
Oracle ASM: Many people allocate lots of small LUNs, because this made sense a long time ago when all you had was just a bunch of disks (JBOD). In fact, many of the practices that DBAs use to configure databases across disks become unnecessary with XIV. Wth XIV, you are better off allocating a few number of very large LUNs from the XIV. The best option was a 1-volume ASM pool with 8MB AU stripe. A single LUN can contain multiple Oracle databases. A single LUN can be used to store all of the logs.
VMware: Over 70 percent of XIV customers use it with VMware. For VMFS, IBM recommends allocating a few number of large LUNs. You can specify the maximum of 2181 GB. Do not use VMware's internal LUN extension capability, as IBM XIV already has thin provisioning and works better to allow XIV to do this for you. XIV Snapshots provide crash-consistent copies without all the VMware overhead of VMware Snapshots.
SAP: For planning purposes, the "SAPS" unit equates roughly to 0.4 IOPS for ERP OLTP workloads, and 0.6 IOPS for BW/BI OLAP workloads. In general, an XIV can deliver 25-30,000 IOPS at 10-15 msec response time, and 60,000 IOPS at 30 msec response time. With SAP, our clients have managed to get 60,000 IOPS at less than 15 msec.
Microsoft Exchange: Even my friends in Redmond could not believe how awesome XIV was during ESRP testing. Five Exchange 2010 servers connected two a pair of XIV boxes using the new 2TB drawers managed 40,000 mailboxes at the high profile (0.15 IOPS per mailbox). Another client found four XIV boxes (720 drives) was able to handle 60,000 mailboxes (5GB max), which would have taken over 4000 drives if internal disk drives were used instead. Who said SANs are obsolete for MS Exchange?
Asynchronous Replication: IBM now has an "Async Calculator" to model and help design an XIV async replication solution. In general, dark fiber works best, and MPLS clouds had the worst results. The latest 10.2.2 microcode for the IBM XIV can now handle 10 Mbps at less than 250 msec roundtrip. During the initial sync between locations, IBM recommends setting the "schedule=never" to consume as much bandwidth as possible. If you don't trust the bandwidth measurements your telco provider is reporting, consider testing the bandwidth yourself with [iPerf] open source tool.
Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.
What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.
How do I evaluate IBM storage solutions in regards to [PCI-DSS] requirements.
Well, we are not lawyers, and some aspects of the PCI-DSS requirements are outside the storage realm. In March 2010, IBM was named ["Best Security Company"] by SC Magazine, and we have secure storage solutions for both disk and tape systems. IBM DS8000 and DS5000 series offer Full Disk Encryption (FDE) disk drives. IBM LTO-4/LTO-5 and TS1120/TS1130 tape drives meet FIPS requirements for encryption. We will provide you contact information on an encryption expert to address the other parts of your PCI-DSS specific concerns.
My telco will only offer FCIP routing for long-distance disk replication, but my CIO wants to use Fibre Channel routing over CWDM, what do I do?
IBM XIV, DS8000 and DS5000 all support FC-based long distance replication across CWDM. However, if you don't have dark fiber, and your telco won't provide this option, you may need to re-negotiate your options.
My DS4800 sometimes reboots repeatedly, what should I do.
This was a known problem with microcode level 760.28, it was detecting a failed drive. You need to replace the drive, and upgrade to the latest microcode.
Should I use VMware snapshots or DS5000 FlashCopy?
VMware snapshots are not free, you need to upgrade to the appropriate level of VMware to get this function, and it would be limited to your VMware data only. The advantage of DS5000 FlashCopy is that it applies to all of your operating systems and hypervisors in use, and eliminates the consumption of VMware overhead. It provides crash-consistent copies of your data. If your DS5000 disk system is dedicated to VMware, then you may want to compare costs versus trade-offs.
Any truth to the rumor that Fibre Channel protocol will be replaced by SAS?
SAS has some definite cost advantages, but is limited to 8 meters in length. Therefore, you will see more and more usage of SAS within storage devices, but outside the box, there will continue to be Fibre Channel, including FCP, FICON and FCoE. The Fibre Channel Industry Alliance [FCIA] has a healthy roadmap for 16 Gbps support and 20 Gbps interswitch link (ISL) connections.
What about Fibre Channel drives, are these going away?
We need to differentiate the connector from the drive itself. Manufacturers are able to produce 10K and 15K RPM drives with SAS instead of FC connectors. While many have suggested that a "Flash-and-Stash" approach of SSD+SATA would eliminate the need for high-speed drives, IBM predicts that there just won't be enough SSD produced to meet the performance needs of our clients over the next five years, so 15K RPM drives, more likely with SAS instead of FC connectors, will continue to be deployed for the next five years.
We'd like more advanced hands-on labs, and to have the certification exams be more product-specific rather than exams for midrange disk or enterprise disk that are too wide-ranging.
Ok, we will take that feedback to the conference organizers.
IBM Tivoli Storage Manager is focused on disaster recovery from tape, how do I incorporate remote disk replication.
This is IBM's Unified Recovery Management, based on the seven tiers of disaster recovery established in 1983 at GUIDE conference. You can combine local recovery with FastBack, data center server recovery with TSM and FlashCopy manager, and combine that with IBM Tivoli Storage Productivity Center for Replication (TPC-R), GDOC and GDPS to manage disk replication across business continuity/disaster recovery (BC/DR) locations.
IBM Tivoli Storage Productivity Center for Replication only manages the LUNs, what about server failover and mapping the new servers to the replicated LUNs?
There are seven tiers of disaster recovery. The sixth tier is to manage the storage replication only, as TPC-R does. The seventh tier adds full server and network failover. For that you need something like IBM GDPS or GDOC that adds this capability.
All of my other vendor kit has bold advertising, prominent lettering, neon lights, bright colors, but our IBM kit is just black, often not even identifying the specific make or model, just "IBM" or "IBM System Storage".
IBM has opted for simplified packaging and our sleek, signature "raven black" color, and pass these savings on to you.
Bring back the SHARK fins!
We will bring that feedback to our development team. ("Shark" was the codename for IBM's ESS 800 disk model. Fiberglass "fins" were made as promotional items and placed on top of ESS 800 disk systems to help "identify them" on the data center floor. Unfortunately, professional golfer [<a href="http://www.shark.com/">Greg Norman</a>] complained, so IBM discontinued the use of the codename back in 2005.)
Where is Infiniband?
Like SAS, Infiniband had limited distance, about 10 to 15 meters, which proved unusable for server-to-storage network connections across data center floorspace. However, there are now 150 meter optical cables available, and you will find Infiniband used in server-to-server communications and inside storage systems. IBM SONAS uses Infiniband today internally. IBM DCS9900 offers Infiniband host-attachment for HPC customers.
We need midrange storage for our mainframe please?
In addition to the IBM System Storage DS8000 series, the IBM SAN Volume Controller and IBM XIV are able to connect to Linux on System z mainframes.
We need "Do's and Don'ts" on which software to run with which hardware.
IBM [Redbooks] are a good source for that, and we prioritize our efforts based on all those cards and letters you send the IBM Redbooks team.
The new TPC v4 reporting tool requires a bit of a learning curve.
The new reporting tool, based on Eclipse's Business Intelligence Reporting Tool [BIRT], is now standardized across the most of the Tivoli portfolio. Check out the [Tivoli Common Reporting] community page for assistance.
An unfortunate side-effect of using server virtualization like VMware is that it worsens management and backup issues. We now have many guests on each blade server.
IBM is the leading reseller of VMware, and understands that VMware adds an added layer of complexity. Thankfully, IBM Tivoli Storage Manager backups uses a lightweight agent. IBM [System Director VMcontrol] can help you manage a variety of hypervisor environments.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.
Bill Bauman, IBM System x Field Technical Support Specialist and System x University celebrity, presented the differences between Grid, SOA and Cloud Computing. I thought this was an odd combination to compare and contrast, but his presentation was well attended.
Grid - this is when two or more independently owned and managed computers are brought together to solve a problem. Some research facilities do this. IBM helped four hospitals connect their computers together into a grid to help analyze breast cancer. IBM also supports the [World Community Grid] which allows your personal computer to be connected to the grid and help process calculations.
SOA - SOA, which stands for Service Oriented Architecture, is an approach to building business applications as a combination of loosely-coupled black-box components orchestrated to deliver a well-defined level of service by linking together business processes. I often explain SOA as the the business version of Web 2.0. You can download a free copy of the eBook "SOA for Dummies" at the [IBM Smart SOA] landing page.
Cloud - A Cloud is a dynamic, scalable, expandable, and completely contractible architecture. It may consist of multiple, disparate, on-premise and off-premise hardware and virtualized platforms hosting legacy, fully installed, stateless, or virtualized instances of operating systems and application workloads.
Tom Vezina, IBM Advanced Technical Sales Specialist, presented "Chaos to Cloud Computing". Survey results show that roughly 70 percent of cloud spend will be for private clouds, and 30 percent for public, hybrid or community clouds. Of the key motivations for public cloud, 77 percent or respondents cited reducing costs, 72 percent time to value, and 50 percent improving reliability.
Tom ran over 500 "server utilization" studies for x86 deployments during the past eight years. Of these, the worst was 0.52 percent CPU utilization, the best was 13.4 percent, and the average was 6.8 percent. When IBM mentions that 85 percent of server capacity is idle, it is mostly due to x86 servers. At this rate, it seems easy to put five to 20 guest images onto a machine. However, many companies encounter "VM stall" where they get stuck after only 25 percent of their operating system images virtualized.
He feels the problem is with the fact most Physical-to-Virtual (P2V) migrations are manual efforts. There are tools available like Novell [PlateSpin Recon] to help automate and reduce the total number of hours spent per migration.
System x KVM Solutions
Boy, I walked into this one. Many of IBM's cloud offerings are based on the Linux hypervisor called Kernel-based Virtual Machine [a href="http://www.linux-kvm.org/page/Main_Page">KVM] instead of VMware or Microsoft Hyper-V. However, this session was about the "other KVM": keyboard video and mouse switches, which thankfully, IBM has renamed to Console Managers to avoid confusion. Presenters Ben Hilmus (IBM) and Steve Hahn (Avocent) presented IBM's line of Local Console Managers (LCM) and Global Console Managers (GCM) products.
LCM are the traditional KVM switches that people are familiar with. A single keyboard, video and mouse can select among hundreds of servers to perform maintenance or check on status. GCM adds KVM-over-IP capabilities, which means that now you can access selected systems over the Ethernet from a laptop or personal computer. Both LCM and GCM allow for two-level tiering, which means that you can have an LCM in each rack, and an LCM or GCM that points to each rack, greatly increasing the number of servers that can be managed from a single pane of glass.
Many severs have a "service processor" to manage the rest of the machine. IBM RSA II, HP iLO, and Dell DRAC4 are some examples. These allow you to turn on and off selected servers. IBM BladeCenter offers an Management Module that allows the chassis to be connected to a Console Manager and select a specific blade server inside. These can also be used with VMware viewer, Virtual Network Computing (VNC), or Remote Desktop Protocol (RDP).
IBM's offerings are unique it that you can have an optical CD/DVD drive or USB external storage attached at the LCM or GCM, and make it look like the storage is attached to the selected server. This can be used to install or upgrade software, transfer log files, and so on. Another great use, and apparently the motivation for having this session in the "Federal Track", is that the USB can be used to attach a reader for a smart card, known as a Common Access Card [CAC] used by various government agencies. This provides two-factor authentication [TFA]. For example, to log into the system, you enter your password (something you know) and swipe your employee badge smart card (something you have). The combination are validated at the selected server to provide access.
I find it amusing that server people limit themselves to server sessions, and storage people to storage sessions. Sometimes, you have to step "outside your comfort zone" and learn something new, something different. Open your eyes and look around a bit. You might just be surprised what you find.
(FTC note: I work for IBM. IBM considers Novell a strategic Linux partner. Novell did not provide me a copy of Platespin Recon, I have no experience using it, and I mention it only in context of the presentation made. IBM resells Avocent solutions, and we use LCM gear in the Tucson Executive Briefing Center.)
Wrapping up my coverage of the annual [2010 System Storage Technical University], I attended what might be perhaps the best session of the conference. Jim Nolting, IBM Semiconductor Manufacturing Engineer, presented the new IBM zEnterprise mainframe, "A New Dimension in Computing", under the Federal track.
The zEnterprises debunks the "one processor fits all" myth. For some I/O-intensive workloads, the mainframe continues to be the most cost-effective platform. However, there are other workloads where a memory-rich Intel or AMD x86 instance might be the best fit, and yet other workloads where the high number of parallel threads of reduced instruction set computing [RISC] such as IBM's POWER7 processor is more cost-effective. The IBM zEnterprise combines all three processor types into a single system, so that you can now run each workload on the processor that is optimized for that workload.
IBM zEnterprise z196 Central Processing Complex (CPC)
Let's start with the new mainframe z196 central processing complex (CPC). Many thought this would be called the z11, but that didn't happen. Basically, the z196 machine has a maximum 96 cores versus z10's 64 core maximum, and each core runs 5.2GHz instead of z10's cores running at 4.7GHz. It is available in air-cooled and water-cooled models. The primary operating system that runs on this is called "z/OS", which when used with its integrated UNIX System Services subsystem, is fully UNIX-certified. The z196 server can also run z/VM, z/VSE, z/TPF and Linux on z, which is just Linux recompiled for the z/Architecture chip set. In my June 2008 post [Yes, Jon, there is a mainframe that can help replace 1500 servers], I mentioned the z10 mainframe had a top speed of nearly 30,000 MIPS (Million Instructions per Second). The new z196 machine can do 50,000 MIPS, a 60 percent increase!
The z196 runs a hypervisor called PR/SM that allows the box to be divided into dozens of logical partitions (LPAR), and the z/VM operating system can also act as a hypervisor running hundreds or thousands of guest OS images. Each core can be assigned a specialty engine "personality": GP for general processor, IFL for z/VM and Linux, zAAP for Java and XML processing, and zIIP for database, communications and remote disk mirroring. Like the z9 and z10, the z196 can attach to external disk and tape storage via ESCON, FICON or FCP protocols, and through NFS via 1GbE and 10GbE Ethernet.
IBM zEnterprise BladeCenter Extension (zBX)
There is a new frame called the zBX that basically holds two IBM BladeCenter chassis, each capable of 14 blades, so total of 28 blades per zBX frame. For now, only select blade servers are supported inside, but IBM plans to expand this to include more as testing continues. The POWER-based blades can run native AIX, IBM's other UNIX operating system, and the x86-based blades can run Linux-x86 workloads, for example. Each of these blade servers can run a single OS natively, or run a hypervisor to have multiple guest OS images. IBM plans to look into running other POWER and x86-based operating systems in the future.
If you are already familiar with IBM's BladeCenter, then you can skip this paragraph. Basically, you have a chassis that holds 14 blades connected to a "mid-plane". On the back of the chassis, you have hot-swappable modules that snap into the other side of the mid-plane. There are modules for FCP, FCoE and Ethernet connectivity, which allows blades to talk to each other, as well as external storage. BladeCenter Management modules serve as both the service processor as well as the keyboard, video and mouse Local Console Manager (LCM). All of the IBM storage options available to IBM BladeCenter apply to zBX as well.
Besides general purpose blades, IBM will offer "accelerator" blades that will offload work from the z196. For example, let's say an OLAP-style query is issued via SQL to DB2 on z/OS. In the process of parsing the complicated query, it creates a Materialized Query Table (MQT) to temporarily hold some data. This MQT contains just the columnar data required, which can then be transferred to a set of blade servers known as the Smart Analytics Optimizer (SAO), then processes the request and sends the results back. The Smart Analytics Optimizer comes in various sizes, from small (7 blades) to extra large (56 blades, 28 in each of two zBX frames). A 14-blade configuration can hold about 1TB of compressed DB2 data in memory for processing.
IBM zEnterprise Unified Resource Manager
You can have up to eight z196 machines and up to four zBX frames connected together into a monstrously large system. There are two internal networks. The Inter-ensemble data network (IEDN) is a 10GbE that connects all the OS images together, and can be further subdivided into separate virtual LANs (VLAN). The Inter-node management network (INMN) is a 1000 Mbps Base-T Ethernet that connects all the host servers together to be managed under a single pane of glass known as the Unified Resource Manager. It is based on IBM Systems Director.
By integrating service management, the Unified Resource Manager can handle Operations, Energy Management, Hypervisor Management, Virtual Server Lifecycle Management, Platform Performance Management, and Network Management, all from one place.
IBM Rational Developer for System z Unit Test (RDz)
But what about developers and testers, such as those Independent Software Vendors (ISV) that produce mainframe software. How can IBM make their lives easier?
Phil Smith on z/Journal provides a history of [IBM Mainframe Emulation]. Back in 2007, three emulation options were in use in various shops:
Open Mainframe, from Platform Solutions, Inc. (PSI)
FLEX-ES, from Fundamental Software, Inc.
Hercules, which is an open source package
None of these are viable options today. Nobody wanted to pay IBM for its Intellectual Property on the z/Architecture or license the use of the z/OS operating system. To fill the void, IBM put out an officially-supported emulation environment called IBM System z Professional Development Tool (zPDT) available to IBM employees, IBM Business Partners and ISVs that register through IBM Partnerworld. To help out developers and testers who work at clients that run mainframes, IBM now offers IBM Rational Developer for System z Unit Test, which is a modified version of zPDT that can run on a x86-based laptop or shared IBM System x server. Based on the open source [Eclipse IDE], the RDz emulates GP, IFL, zAAP and zIIP engines on a Linux-x86 base. A four-core x86 server can emulate a 3-engine mainframe.
With RDz, a developer can write code, compile and unit test all without consuming any mainframe MIPS. The interface is similar to Rational Application Developer (RAD), and so similar skills, tools and interfaces used to write Java, C/C++ and Fortran code can also be used for JCL, CICS, IMS, COBOL and PL/I on the mainframe. An IBM study ["Benchmarking IDE Efficiency"] found that developers using RDz were 30 percent more productive than using native z/OS ISPF. (I mention the use of RAD in my post [Three Things to do on the IBM Cloud]).
What does this all mean for the IT industry? First, the zEnterprise is perfectly positioned for [three-tier architecture] applications. A typical example could be a client-facing web-server on x86, talking to business logic running on POWER7, which in turn talks to database on z/OS in the z196 mainframe. Second, the zEnterprise is well-positioned for government agencies looking to modernize their operations and significantly reduce costs, corporations looking to consolidate data centers, and service providers looking to deploy public cloud offerings. Third, IBM storage is a great fit for the zEnterprise, with the IBM DS8000 series, XIV, SONAS and Information Archive accessible from both z196 and zBX servers.
I have arrived safely to San Francisco, and was able to check-in at the hotel, pick up my registration badge for Oracle OpenWorld 2011, and attend the first keynote session. This is the largest Oracle OpenWorld event to-date, with over 45,000 attendees from 117 different countries. There are 520,000 square feet of exhibition floor, and over 2,400 educational sessions. The conference is spread across the different buildings of the Moscone center, as well as nearby hotels. On average, attendees will walk seven miles during the week.
Larry Ellison was the keynote speaker for this first kick-off session. He focused almost exclusively on server and storage hardware. He feels that business is all about moving data, not doing integer math.
At the beginning of 2011, Oracle had only sold about 1,000 Exadata, but they have a sales target to sell an additional 3,000 Exadata boxes by year end.
The Exadata offers up to 10x columnar compression, and has 10x faster bandwidth (40Gbps Infiniband versus 4Gbps FCP). If you have a 100TB database, it would take up only 10TB of disk with this approach. He claims that the 90TB of disk you don't have to buy can then be used to buy more DRAM and/or Flash SSD.
(Realistically, since SSD is 15x more expensive than spinning disk, you can only purchase about 6TB of Flash for the 90TB you save on disk!)
Larry claims the design point for Exadata and Exalogic was to offer a system that was more powerful than IBM's fastest P795 computer, but cheaper than commodity x86 hardware. His secret is to "Parallel everything" for faster performance, and no single points of failure (SPOF). Exadata offers up to 10-50x faster query, and 4-10x faster OLTP. To keep costs low, Exadata uses all commodity hardware except the Infiniband. He cited various customer examples:
A company replaced 36 Teradata with 3 Exadata and result was application was 8x faster.
Banco Chile 9x faster than previous system
Deutsche Post 60x faster
Sogetti gets 60x faster backups.
French bank BNP Paribas 17x faster and no change to applications.
Proctor & Gamble 18x faster
Merck 5x faster
Turkcell 250TB compressed to 25TB, 10x faster
The problem was that in each example, he said what it was compared against was the old previous system, which varies and could have been an older Sun system, or an old system from HP, IBM or Dell. Perhaps it was a freudian slip, but Larry mistakenly said "Paralyze" your applications, when he probably meant to "Parallelize".
Of all their 380,000 Oracle customers, 70 percent have SPARC/Solaris and/or Linux. Last week, Oracle announced the new SPARC-T4, which Larry claimed was 5x faster than the previous SPARC-T3. Larry feels that for the first time ever, a non-IBM CPU can challenge the long-standing rein of the IBM POWER series processor. Larry admitted that the IBM POWER7 chip actually did some tasks faster than the SPARC-T4, so his work is not yet done, but they plan to offer a new SPARC-T5 next year that will be 2x better than the SPARC-T4.
Larry compared the I/O bandwidth of serv ers based on SPARC-T4, compared to POWER7, and found that the SPARC-T4 has double the I/O bandwidth, for a cost that was only about 1/4 the cost of a mainframe. IBM offers both. POWER7-based servers for CPU-intensive workloads, and System z (S/390)-based systems for I/O-intensive workloads. Larry feels that even though POWER7 is superior than SPARC-T4 for mathematical calculations, all business applications are focused on I/O-bandwidth to move data, not computations.
Larry claims the new SPARC-T4 can do 1.2 million IOPS. He uses 40 Gbps Infiniband instead of traditional SAN-attached FCP solutions.
A new "box" called Exalytics, combines their commodity hardware platform with a hueristic adaptive in-memory cache, their latest "me-too" solution that compares with what IBM already offers in [IBM SolidDB]. In fact, their me-too is not even internally developed, but rather the result of an acquisition of a company called "Times Ten". I thought it was interesting that the only piece of Oracle software mentioned during Larry's 90-minute speach, was this piece of acquired technology. The new Exalytics product run on a small rack and grow, analyzing relational data, non-relational OLAP, as well as unstructured documents. The result is what Larry called "the Speed of Light".
He also mentioned that Bob Shimp would kick-off the Cloud later in the week. Given that Larry himself thought that Cloud was a stupid, over-marketed term that nobody has deployed over the past few years, to a complete believer, claiming that over 20 live demos will be given this year on Cloud.
Perhaps the funniest quote was his motivation to use Infiniband as the interconnect
"Ethernet was invented by Xerox when I was a child."
-- Larry Ellison
Here are some sessions that IBM is featuring on Monday. Note the first two are Solution Spotlight sessions at the IBM Booth #1111 where I will be most of the time.

Application Strategy: Charting the Course for Maximum Business Value
10/03/11, 3:30 p.m. – 4:30 p.m., OpenWorld session #39061
Presenter: Mike Marchildon, IBM
The industry is undergoing a shift from single Enteprise Resource Planning (ERP) application to second-generation platforms containing diverse yet interdependent systems. This shift presents opportunities and challenges for both IT and the business.
Monday morning of the [Oracle OpenWorld 2011] conference had Joe Tucci, CEO of EMC, present the keynote. Joe indicated that I.T. stands for "Industry in Transition". He had a chart that showed the history of IT, from the mainframe and mini-computer, to the PC and client/server era, and now to the Cloud era. He called these "waves of disruption". The catalysts for change are a "Budge Dilemma", "Information Deluge" and "Cyber Security". The keynote was very similar to what EMC presented at [VMworld] conference earlier this summer.
"We have failed our customers. Over the past 10 years, they spend 73% to maintain their existing systems, and only 27% for new."
--- Joe Tucci, EMC
While many people equate "EMC" and "Failure", I believe Joe was referring not just to his own company, but most of the other IT vendors as well. Analysts predict that from January 1, 2010 to December 31, 2019, the world of stored data will grow from 0.9 ZB to 35.2 ZB, which represents a 44x increase. During that same time, IT staff is only expected to grow 50 percent. A staggering 90 percent of this data will be unstructured (non-database) content. Meanwhile, the average company gets cyber-attacked 300 times per week.
The answer is Cloud Computing. A few years ago, EMC was trying to get people to go "private cloud" route instead of "public cloud", they now have a more realistic "hybrid cloud" approach similar to IBM. Of the clients that EMC works with, 35 percent are implementing some form of cloud, and another 30 percent are planning to. The tenents of Hybrid Cloud are "Efficiency", "Control" and "Choice" which equals "Agility".
Joe also mentioned that there is now a new "layering" for IT. Instead of storage, switches and servers, we have a cloud platform of shared resources, mobile devices like smartphones and tablets, and management.
Joe feels there is a massive opportunity where Cloud meets Big Data. A cute video showed a driver wearing a motorcycle helmet so you can't see his face get into an under-powered car with "VNXe" on the license plate. He punches in "Cloud and Big Data" into the GPS navigation system, and starts out on city streets. Then the car transforms to an under-utilized family sedan "VNX" on a highway in the middle of the desert, then transforms to an over-priced sports car labeled "VMAX" as it climbs into the mountains surrounded by fog. The video borrowed the "CARS" theme from the videos IBM developed for its 2008 launch of "Information Infrastructure" initiative.
EMC's Pat Gelsinger (CTO) and fellow blogger Chad Sakac did some demos of VMware vCenter. They called the VMware vSphere "the Datacenter-wide OS" indicating that EMC storage has 75 points of integration with their "partner" (VMware is majority-owned by EMC, so I am not sure if partner is the right term). If you don't count Itanium, SPARC, POWER and IBM Syste z architectures, VMware enjoys over 80 percent marketshare for server virtualization.
(Full disclosure: IBM is the leading reseller of VMware.)
Pat claims that 40 percent of Oracle Apps at EMC run VMware. For the longest time, Oracle refused support its apps on VMware, but they relaxed this restrictive policy back in 2009. Today, nearly 25 percent of Oracle Apps run virtualized. EMC claims that they can support 5 million VMs on a single VMAX, and can generate 1 million IOPS from a single VMware ESX host.
Chad did a demo of vFabric which allows a vCenter plug-in to kick up Database instances of OracleDB, MySQL, Hadoop, PostgreSQL, and GreenPlum (GreenPlum is EMC's version of open-source PostgreSQL).
Chad showed that VMware vMition could move workloads from servers without solid-state, to servers that are flash-enabled. Lightweight workloads can be moved from DAS-enabled servers to compute-enabled storage devices like their EMC Isilon. (EMC acquired Isilon to offer their me-too version of IBM's Scale-Out NAS [SONAS] product.) EMC announced their first "Solid-State on a PCIe card" from their Project Lightning initiative. These are 320 GB capacity, so they sounded like a me-too versino of IBM's [Fusion-io IOdrive] cards that IBM has had available for quite some time now.
Next, Pat and Chad talked about Big Data. The world is transforming from a manual scale-up model to an automated scale-out architecture. Moving from "islands" to "pools". They used a cute example of Car Insurance. Business Analytics were able to review a safe drivers record, including the driver's Facebook and Twitter activity, and give him a discount, and then review the bad driving habits of another driver, and raise the bad driver's rates.
EMC announced their "GreenPlum Analytics Platform" (GAP?). I often tell people that if you want to predict what EMC will announce next, just look at what IBM announced 18 months ago. This new platform sounds like their me-too version of IBM's [Smart Analytics System].
After EMC, Judith Sim from Oracle introduced the Ed Lee, the Mayor of San Francisco which was just named the "Greenest city in North America". He thanked the audience for contributing an estimated $100 million USD to his local economy. Also, he was happy that by eliminating paper-based handouts and conference materials, the audience saved 1,636 trees.
Mark Hurd, formerly CEO of HP, and now president of Oracle, gave some highlights of 2011, and what Oracle's strategy is going forward. He said that Oracle plans to provide complete stacks, complete choice, and have each component of the stack be best-of-breed. In 2011, Oracle introduced the new MySQL 5.5 database, Java 7 programming language, and the Solaris 11 operating system with ZFS file system. Oracle spent $4 Billion in R&D, and gained 20 percent growth in software licenses, which gave them 33 percent growth fiscally for 2011 year. Oracle acquired Larry Ellison's [Pillar Data] storage company. Oracle also launched a [Database Appliance].
Thomas Kurian, another Oracle executive, finished the keynote session. He started with yet another chart showing the historical transition from Mainframe to Tablet. He indicated that leading-edge OracleDB and their Fusion middleware combined with industry standard hardware provides 5-30x faster queries, 4-10x less disk space, and simplifies the data center footprint. Their Exadata provides what he likes to call "Hierarchical Storage Management" between DRAM, Flash Solid-State, and spinning disk.
(Note: I started my career at IBM in 1986 working on a product called DFHSM, the Data Facility Hierarchical Storage Manager! It is now a vibrant component of DFSMS, part of IBM's z/OS mainframe operating system.)
ps this new announcement is to address that deficiency.
Finally, Oracle announced their "Exadata Storage Expansion Rack". Many people realized that the Exadata was under-provisioned for storage, which explains why they have only sold a few thousand of them, so perha
If you are attending Oracle OpenWorld, here are sessions for Tuesday that IBM is featuring. Note the first two are Solution Spotlight sessions at the IBM Booth #1111 where I will be most of the time.

Presenters: Arnaud Wingelaar, IBM; Geetha Sundaram; Agnes Zhang, Oracle
Hear customer success stories about upgrading Siebel CRM. Learn best practices on upgrading with lowered cost, or achieving a high-availability upgrade with zero downtime and reduced risk.
Tuesday morning at the [Oracle OpenWorld 2011] conference started with another keynote session. This time, Michael Dell, founder, chairman and CEO of Dell, Inc., presented. Over the past nine years, he feels "the line between business and IT is going away." Michael claims that "Dell is no longer a PC company", and instead is focusing on data center solutions and services to be more like IBM.
John Fowler, Executive VP for Oracle Hardware, claims that Oracle has a single team for hardware development. The SPARC-T4 is their newest chip, with 8 cores and 64 dynamic threads, running at 3.0 GHz. It has on-chip 10GbE ethernet, PCIe, DDR3 Memory controllers and Crypto features. For storage, Oracle now offers four different offerings:
Exadata (as Database storage)
ZFS Storage Array (NAS)
Pillar Axiom (block-level I/O)
Edward Screven, Chief Corporate Architect at Oracle, indicated that the new Oracle Linux kernel allows for zero downtime patches, meaning that you can update the OS while applications are running without a reboot. The OracleVM (based on open-source XEN) supports both x86 and SPARC-based server hosts. On x86, it can run Linux, Solaris and Windows guests. On SPARC, it can run Linux and Solaris guests.
John Loaiza, Oracle Senior VP, explained the Exadata. It has 168 disk drives and 56 PCIe Flash Cards, connected via 40Gbps Infiniband. The Exadata keeps all data on spinning disk, with "warm data" cached on Flash, and "hot data" cached on DRAM. This is similar to IBM's Easy Tier feature on the DS8000, SVC and Storwize V7000.
Brad Cameron, Senior Director, explained Exalogic, which pre-dates Oracle's acquisition of Sun Microsystems. The idea was to build an x86 machine for running Java applications on Oracle WebLogic. The Exalogic can connect via Infiniband to an Exadata to access database information, and to 10GbE ethernet for the rest of the servers and clients. Whether you get the quarter, half or full-rack system, you get 40TB of NAS storage.
Ganesh Ramamurthy, Oracle VP of Hardware Engineering, presented the SPARC Supercluster. This combines the storage cells from Exadata, the compute nodes from Exalogic, shared NAS storage using ZFS file system, and Solaris 11 with OracleVM. Taking a cue from IBM's zEnterprise Unified Resource Manager, Oracle is offering centralized management for all the layers in their SPARC Supercluster stack. The SPARC Supercluster is intended as general purpose machine, and can be used to run non-Oracle applications like SAP. From a storage perspective, he claims that the storage in the SPARC Supercluster is 2.5x better than EMC VMAX, which basically puts it comparable to IBM XIV pricing.
