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.
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.
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!
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.
The new [IBM System Storage Tape Controller 3592 Model C07] is an upgrade to the previous C06 controller. Like the C06, the new 3592-C07 can have up to four FICON (4Gbps) ports, four FC ports, and connect up to 16 drives. The difference is that the C07 supports 8Gbps speed FC ports, and can support the [new TS1140 tape drives that were announced on May 9]. A cool feature of the C07 is that it has a built-in library manager function for the mainframe. On the previous models, you had to have a separate library manager server.
Crossroads ReadVerify Appliance (3222-RV1)
IBM has entered an agreement to resell [Crossroads ReadVerify Appliance], or "RV1" for short. The RV1 is a 1U-high server with software that gathers information on the utilization, performance and health for a physical tape environment, such as an IBM TS3500 Tape Library. The RV1 also offers a feature called "ArchiveVerify" which validates long-term retention archive tapes, providing an audit trail on the readability of tape media. This can be useful for tape libraries attached behind IBM Information Archive compliance storage solution, or the IBM Scale-Out Network Attached Storage (SONAS).
As an added bonus, Crossroads has great videos! Here's one, titled [Tape Sticks]
Linear Tape File System (LTFS) Library Edition Version 2.1
While the hardware is all refreshed, the overall "scale-out" architecture is unchanged. Kudos to the XIV development team for designing a system that is based entirely on commodity hardware, allowing new hardware generations to be introduced with minimal changes to the vast number of field-proven software features like thin provisioning, space-efficient read-only and writeable snapshots, synchronous and asynchronous mirroring, and Quality of Service (QoS) performance classes.
The new XIV Gen3 features an Infiniband interconnect, faster 8Gbps FC ports, more iSCSI ports, faster motherboard and processors, SAS-NL 2TB drives, 24GB cache memory per XIV module, all in a single frame IBM rack that supports the IBM Rear Door Heat Exchanger. The results are a 2x to 4x boost in performance for various workloads. Here are some example performance comparisons:
Disclaimer: Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. Your mileage may vary.
In a Statement of Direction, IBM also has designed the Gen3 modules to be "SSD-ready" which means that you can insert up to 500GB of Solid-State drive capacity per XIV module, up to 7.5TB in a fully-configured 15 module frame. This SSD would act as an extension of DRAM cache, similar to how Performance Accelerator Modules (PAM) on IBM N series.
IBM will continue to sell XIV Gen2 systems for the next 12-18 months, as some clients like the smaller 1TB disk drives. The new Gen3 only comes with 2TB drives. There are some clients that love the XIV so much, that they also use it for less stringent Tier 2 workloads. If you don't need the blazing speed of the new Gen3, perhaps the lower cost XIV Gen2 might be a great fit!
As if I haven't said this enough times already, the IBM XIV is a Tier-1, high-end, enterprise-class disk storage system, optimized for use with mission critical workloads on Linux, UNIX and Windows operating systems, and is the ideal cost-effective replacement for EMC Symmetrix VMAX, HDS USP-V and VSP, and HP P9000 series disk systems, . Like the XIV Gen2, the XIV Gen3 can be used with IBM System i using VIOS, and with IBM System z mainframes running Linux, z/VM or z/VSE. If you run z/OS or z/TPF with Count-Key-Data (CKD) volumes and FICON attachment, go with the IBM System Storage DS8000 instead, IBM's other high-end disk system.
