Long-time readers of my blog know that typically IBM makes its announcements on Tuesdays, but this week, we had an announcement today, Wednesday!
IBM announced agreements with Brocade, Cisco and Juniper Networks to help build more dynamic infrastructures. An IBM study estimates that the "digital footprint" of each person will grow from 1TB today to 16TB by the year 2020, and all of that data will need bandwidth to get around.IBM’s Data Center Networking (DCN) Initiative is focused on providing clients with solutions to address these three key areas in networking:
Partner for choice of networking products based and open standards to ensure clients can select from a full range of hardware options for data center networks. IBM will build on its strong partnerships with leading networking vendors to provide greater customer choice.
Integrate with IBM Data Center Products and Services. IBM continues to deliver a comprehensive portfolio of services for network design, integration and management from IBM Global Technology Services (GTS).
IBM differentiates itself with Common Data Center Management, where we can bring together software products, such as IBM Systems Director and Tivoli portfolio, to create what we refer to as a "Unified Service Management" software platform.
Here's a sample of what IBM announced:
IBM continues its strategic support for Fibre Channel over Ethernet (FCoE) with a Converged B32 switch, and Converged Network Adapters (CNA) for IBM System x servers. A CNA card does the job of both the Ethernet Network Interface Card (NIC) as well as the Fibre Channel Host Bus Adapter (HBA), reducing the number of cables from each server.
IBM and its Business Partners will resell the Cisco Nexus 5000 Series Switches, a leading family of high-performance, low-latency switches for data center networks supporting lossless 10GbE, Fibre Channel and Fibre Channel over Ethernet (FCoE).
IBM will OEM selected Juniper EX and MX switches and routers. This expands upon IBM and Juniper's long-term relationship that includes a reseller agreement with IBM Global Technology Services, collaboration on Juniper's Stratus Project, and IBM's ten worldwide Cloud Labs.
Well, it's Tuesday, and you know what that means? IBM announcements!
Today we had several for the IBM System Storage product line. Here are some of them:
DS8000 gets thinner, leaner and faster
The 4.3 level of microcode for the IBM System Storage DS8000 series disk systems [announced enhancements] for both fixed block architecture (FBA) LUNs and count key data (CKD) volumes.
For FBA LUNs that attach to Linux, UNIX and Windows distributed systems, IBM announced DS8000 Thin Provisioning native support. Of course, many people already had this by putting IBM System Storage SAN Volume Controller (SVC) in front, but now DS8000 clients out there without SVC can also achieve benefits ofthin provisioning. This support also improves quick initialization a whopping 2.6 times faster.
For CKD volumes attached to z/OS on System z mainframes, IBM announced zHPF multitrack support for z/OS 1.9 and above. zHPF provide high performance FICON performance, and can now handle multitrack I/O transfers foreven better performance for zFS, HFS, PDSE, and extended striped data sets.
XIV gets better connected
A lot of XIV[announced enhancements] and preview announcements centered around better connectivity. Here's a run down:
Better host attachment connectivity by beefing up the interface modules that hold the FCP and iSCSI interface cards. XIV disk arrays have 3 to 6 of these in different configurations, and since they manage both their own disks,as well as receive host I/O requests for other disks, are basically doing double-duty.These interface modules can now be ordered as [Dual-CPU] modules.
Better infrastructure management by connecting XIV with the industry standard SMI-S interface to IBM Tivoli Storage Productivity Center. Now, XIV can be part of the single pane of glass console that manages all of your other disk arrays, tape libraries and SAN fabrics.
Better copy services for backups by connecting XIV with IBM Tivoli Storage Manager Advanced Copy Services. TSM for Advanced Copy Services is application aware and can coordinate XIV Snapshots similar to its current support for SVC and DS8000 FlashCopy capabilities.
Better connectivity to security systems by supporting LDAP credentials. Before, you had individual userid and passwords for each XIV, and these were probably different than all the other userid/password combinations you have for every other box on your data center floor. IBM is working on getting all products to support theLightweight Directory Access Protocol, or [LDAP] so that we can reach the nirvana of "single sign-on",one userid/password per administrator for all IT devices in the company.
Better support with flexible warranty periods and non-disruptive code load options.
Better remote copy support by connecting to sites far, far away. IBM previewed that it will provideasynchronous disk mirroring from one XIV to another XIV natively. Before this, XIV's synchronous mirroring was limited to 300km distances. Many of our clients do long distance global mirroring of their XIV today behind an SVC, but again, for those out there that don't yet have an SVC, this can be a reasonable alternative.
TS7650 ProtecTIER data deduplication appliance now offers "no dedupe" option
In what some might consider a surprising move, IBM announced a "no dedupe" licensing option on their premiere deduplication solution, which somewhat reminds me of IBM's NOCOPY option on DS8000 FlashCopy. At first I thought "Are you kidding me?!?!" However, this new license option allows the TS7650 appliance to compete with other virtual tape libraries (VTL) that do not offer deduplication capability on an even playing field. It also allows TS7650 to be used for data that doesn'tdedupe very well, such as seismic recordings, satellite images, or what have you. There are also clients who do not yet feel comfortable to dedupe their financial records for compliance reasons.This option now allows IBM to withdraw from marketing the TS7530 non-dedupe library. Having one technology thatdoes both dedupe and no-dedupe is better than offering two separate libraries based on different technologies.
The ProtecTIER series also announced [IP remote distance replication]. This can be used to replicate virtualtape cartridges in one ProtecTIER over to another ProtecTIER at a remote location. You can decide to replicateall or just a subset of your virtual tapes, and this feature can be used to migrate, merge or split ProtecTIERconfigurations as your needs grow. Before this support, our TS7650G clients replicated the disk repositoryusing native disk array replication technology, such as Global Mirror on the DS8000, but that meant that all data was replicated over to the secondary site. Now, with this new IP replication feature, you can be selective, and replicate only those virtual tapes that are mission critical.
The appliance now supports up to 36TB of disk capacity, and the new "IBM i" operating system on System i servers,formerly known as i5/OS.
GPFS does Windows
IBM's General Parallel File System (GPFS) has the lion's marketshare of file systems used in the [Top 500 Supercomputers]. For a while, it was limited to just Linux and AIX operating system support, but version 3.3 [extends this to Windows 2008 on 64-bit architectures]. GPFS isthe file system used in IBM's Scale-Out File Services, the underlying technology of IBM's Cloud Computing and Storage offerings.
This week I am in Chicago for the IBM Storage and Storage Networking Symposium, which coincides with the System x and BladeCenter Technical Conference. This allows the 800 attendees to attend both storage or server presentations at their convenience. There were hundreds of sessions, over 20 time slots, so for each time slot, you have 15 or so topics to choose from.Mike Kuhn kicked off the series of keynote sessions. Here's my quick recap of each one:
Curtis Tearte, General Manager, IBM System Storage
Curtis replaced Andy Monshaw as General Manager for IBM System Storage. His presentation focused on how storage fits into IBM's Dynamic Infrastructure strategy. Some interesting points:
a billion camera-enabled cell phones were sold in 2007, compared to 450 million in 2006.
IBM expects that there will be 2 billion internet users by 2011, as well as trillions of "things".
In the US, there were 2.2 million medical pharmacy dispensing errors resulting for handwritten prescriptions.
Time wasted looking for parking spaces in Los Angeles consumed 47,000 gallons of gasoline, and generated 730 tons of carbon dioxide.
In the US, 4.2 billion hours are lost, and 2.9 billion gallons of gas consumed, due to traffic congestion.
Over the past decade, servers went from 8 watts to 100 watts per $1000 US dollars.
Data growth appears immune to the economic recession. The digital footprint per person is expected to grow from 1TB today to over 15TB by 2020.
10 hours of YouTube videos are uploaded every minute.
Bank of China manages 380 million bank accounts, processing over 10,000 transactions per second.
At the end of the session, Curtis transitioned from demonstrating his knowledge and passion of storage to his knowledge and passion in his favorite sport: baseball. Chicago is home to both the Cubs and the White Sox.
Roland Hagan, Vice President Business Line Executive, System x
IBM sets the infrastructure agenda for the entire industry. The Dynamic Infrastructure initiative is not just IT, but a complete end-to-end view across all of the infrastructures in play, including transportation, manufacturing, services and facilities.Companies spent over $60 billion US dollars on servers last year. Of these, 53 percent for x86-based servers, 9 percent for Itanium-based, 26 percent for RISC-based (POWER6, SPARC, etc.), and 11 percent mainframe. Theeconomic downturn has impacted revenues, but the percentages continue about the same.
The dominant deployment model remains one application per server. As a result, power, cooling and management costs have grown tremendously. There are system admins opposed to consolidating server images with VMware, Hyper-V, Xen or other server virtualizaition technologies. Roland referred to these admins as "server huggers".To help clients adopt cloud computing technologies, IBM introduced [Cloudburst] appliances. IBM plans to offer specialized versions for developers, for service providers, and for enterprises.
IBM's Enterprise-X Architecture is what differentiates IBM's x86-based servers from all the competitors, surrounding Intel and AMD processors with technology that provides distinct advantages. For example, to support server virtualization, IBM's eX4 provides support for more memory, which often is more critical than CPU resources when deploying large number of guest OS images. IBM System x servers have an integrated management module (IMM) and was the first to change over from BIOS to the new Unified Extensible Firmware Interface [UEFI] standard.
IBM servers offer double the performance, consume half the power, and cost a third less to manage, than comparably priced servers from competitors. Of the top 20 more energy efficient server deployments, 19 are from IBM. Roland cited customer reference SciNet, a 4000-server supercomputer with 30,000 cores based on IBM [iDataPlex] servers. At 350 TeraFLOPs it is ranked #16 fastest supercomputer in the world, and #1 in Canada. With apower usage effectiveness (PUE) less than 1.2, it also is very energy efficient. This means that for every 12 watts of electricity going in to the data center, 10 watts are used for servers, storage and networking gear, andonly 2 watts used for power and cooling. Traditional data centers have PUE around 2.5, consuming 25 watts total for every 10 watts used by servers, storage and networking gear.
Clod Barrera, Distinguished Engineer, Chief Technical Strategist for IBM System Storage
Clod presented trends and directions for disk and tape technology, disk and tape systems, and the direction towards cloud computing.
Continuing my week in Chicago for the IBM Storage and Storage Networking Symposium and System x and BladeCenter Technical Conference, I presented a variety of topics.
Hybrid Storage for a Green Data Center
The cost of power and cooling has risen to be a #1 concern among data centers. I presented the following hybrid storage solutions that combine disk with tape. These provide the best of both worlds, the high performance access time of disk with the lower costs and reduced energy consumption of tape.
IBM [System Storage DR550] - IBM's Non-erasable, Non-rewriteable (NENR) storage for archive and compliance data retention
IBM Grid Medical Archive Solution [GMAS] - IBM's multi-site grid storage for PACS applications and electronic medical records[EMR]
IBM Scale-out File Services [SoFS] - IBM's scalable NAS solution that combines a global name space with a clustered GPFS file system, serving as the ideal basis for IBM's own[Cloud Computing and Storage] offerings
Not only do these help reduce energy costs, they provide an overall lower total cost of ownership (TCO) thantraditional WORM optical or disk-only storage configurations.
The Convergence of Networks - Understanding SAN, NAS and iSCSI in the Data Center Network
This turned out to be my most popular session. Many companies are at a crossroads in choosing data and storage networking solutions in light of recent announcements from IBM and others. In the span of 75 minutes, I covered:
Block storage concepts, storage virtualization and RAID levels
File system concepts, how file systems map files to block storage
Network Attach Storage, the history of the NFS and CIFS protocols, Pros and Cons of using NAS
Storage Area Networks, the history of SAN protocols including ESCON, FICON and FCP, Pros and Cons of using SAN
IP SAN technologies, iSCSI and Fibre Channel over Ethernet (FCoE), Pros and Cons of using this approach
Network Convergence with Infiniband and Fibre Channel over Convergence Enhanced Ethernet (FCoCEE), why Infiniband was not adopted historically in the marketplace as a storage protocol, and the features and enhancements of Convergence Enhanced Ethernet (CEE) needed to merge NAS, SAN and iSCSI traffic onto a single converged data center network [DCN]
Yes, it was a lot of information to cover, but I managed to get it done on time.
IBM Tivoli Storage Productivity Center version 4.1 Overview and Update
In conferences like these, there are two types of product-level presentations. An "Overview" explains howproducts 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. I decided to combine these into one sessionfor IBM's new version of [Tivoli Storage Productivity Center].I was one of the original lead architects of this product many years ago, and was able to share many personalexperiences 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.
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 performingILM assessments for clients, and now there are dozens of IBM practitioners in Global Technology Services andSTG Lab Services that do this full time. This is a topic I cover frequently at the IBM Executive Briefing Center[EBC], because it addressesseveral 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
I did not get as many attendees as I had hoped for this last one, as I was competing head-to-head in the same time slot as Lee La Frese covering IBM's DS8000 performance with Solid State Disk (SSD) drives, John Sing covering Cloud Computing and Storage with SoFS, and Eric Kern covering IBM Cloudburst.
I am glad that I was able to make all of my presentations at the beginning of the week, so that I can then sit back and enjoy the rest of the sessions as a pure attendee.
