Over on the Tivoli Storage Blog, there is an exchange over the concept of a "Storage Hypervisor". This started with fellow IBMer Ron Riffe's blog post [Enabling Private IT for Storage Cloud -- Part I], with a promise to provide parts 2 and 3 in the next few weeks. Here's an excerpt:
"Storage resources are virtualized. Do you remember back when applications ran on machines that really were physical servers (all that “physical” stuff that kept everything in one place and slowed all your processes down)? Most folks are rapidly putting those days behind them.
In August, Gartner published a paper [Use Heterogeneous Storage Virtualization as a Bridge to the Cloud] that observed “Heterogeneous storage virtualization devices can consolidate a diverse storage infrastructure around a common access, management and provisioning point, and offer a bridge from traditional storage infrastructures to a private cloud storage environment” (there’s that “cloud” language). So, if I’m going to use a storage hypervisor as a first step toward cloud enabling my private storage environment, what differences should I expect? (good question, we get that one all the time!)
The basic idea behind hypervisors (server or storage) is that they allow you to gather up physical resources into a pool, and then consume virtual slices of that pool until it’s all gone (this is how you get the really high utilization). The kicker comes from being able to non-disruptively move those slices around. In the case of a storage hypervisor, you can move a slice (or virtual volume) from tier to tier, from vendor to vendor, and now, from site to site all while the applications are online and accessing the data. This opens up all kinds of use cases that have been described as “cloud”. One of the coolest is inter-site application migration.
A good storage hypervisor helps you be smart.
Application owners come to you for storage capacity because you’re responsible for the storage at your company. In the old days, if they requested 500GB of capacity, you allocated 500GB off of some tier-1 physical array – and there it sat. But then you discovered storage hypervisors! Now you tell that application owner he has 500GB of capacity… What he really has is a 500GB virtual volume that is thin provisioned, compressed, and backed by lower-tier disks. When he has a few data blocks that get really hot, the storage hypervisor dynamically moves just those blocks to higher tier storage like SSD’s. His virtual disk can be accessed anywhere across vendors, tiers and even datacenters. And in the background you have changed the vendor storage he is actually sitting on twice because you found a better supplier. But he doesn’t know any of this because he only sees the 500GB virtual volume you gave him. It’s 'in the cloud'."
"Let’s start with a quick walk down memory lane. Do you remember what your data protection environment looked like before virtualization? There was a server with an operating system and an application… and that thing had a backup agent on it to capture backup copies and send them someplace (most likely over an IP network) for safe keeping. It worked, but it took a lot of time to deploy and maintain all the agents, a lot of bandwidth to transmit the data, and a lot of disk or tapes to store it all. The topic of data protection has modernized quite a bit since then.
Fast forward to today. Modernization has come from three different sources – the server hypervisor, the storage hypervisor and the unified recovery manager. The end result is a data protection environment that captures all the data it needs in one coordinated snapshot action, efficiently stores those snapshots, and provides for recovery of just about any slice of data you could want. It’s quite the beautiful thing."
At this point, you might scratch your head and ask "Does this Storage Hypervisor exist, or is this just a theoretical exercise?" The answer of course is "Yes, it does exist!" Just like VMware offers vSphere and vCenter, IBM offers block-level disk virtualization through the SAN Volume Controller(SVC) and Storwize V7000 products, with a full management support from Tivoli Storage Productivity Center Standard Edition.
SVC has supported every release of VMware since the 2.5 version. IBM is the leading reseller of VMware, so it makes sense for IBM and VMware development to collaborate and make sure all the products run smoothly together. SVC presents volumes that can be formatted for VMFS file system to hold your VMDK files, accessible via FCP protocol. IBM and VMware have some key synergies:
Management integration with Tivoli Storage Productivity Center and VMware vCenter plug-in
VAAI support: Hardware-assisted locking, hardware-assisted zeroing, and hardware-assisted copying. Some of the competitors, like EMC VPLEX, don't have this!
Space-efficient FlashCopy. Let's say you need 250 VM images, all running a particular level of Windows. A boot volume of 20GB each would consume 5000GB (5 TB) of capacity. Instead, create a Golden Master volume. Then, take 249 copies with space-efficient FlashCopy, which only consumes space for the modified portions of the new volumes. For each copy, make the necessary changes like unique hostname and IP address, changing only a few blocks of data each. The end result? 250 unique VM boot volumes in less than 25GB of space, a 200:1 reduction!
Support for VMware's Site Recovery Manager using SVC's Metro Mirror or Global Mirror features for remote-distance replication.
Data center federation. SVC allows you to seamlessly do vMotion from one datacenter to another using its "stretched cluster" capability. Basically, SVC makes a single image of the volume available to both locations, and stores two physical copies, one in each location. You can lose either datacenter and still have uninterrupted access to your data. VMware's HA or Fault Tolerance features can kick in, same as usual.
But unlike tools that work only with VMware, IBM's storage hypervisor works with a variety of server virtualization technologies, including Microsoft Hyper-V, Xen, OracleVM, Linux KVM, PowerVM, z/VM and PR/SM. This is important, as a recent poll on the Hot Aisle blog indicates that [44 percent run 2 or more server hypervisors]!
Join the conversation! The virtual dialogue on this topic will continue in a [live group chat] this Friday, September 23, 2011 from 12 noon to 1pm EDT. Join me and about 20 other top storage bloggers, key industry analysts and IBM Storage subject matter experts to discuss storage hypervisors and get questions answered about improving your private storage environment.
This last one on how to build your own Watson, Jr. has gotten over 69,000 hits! While several people told me they plan to build their own, I have not heard back from anyone yet, so perhaps it is taking longer than expected.
IBM and Wellpoint announced this week that it will be [putting Watson to work] in healthcare. [Wellpoint] is one of the largest health benefits company in the United States, with over 70 million people served through its affiliate plans and its various subsidiaries. I am one of the development lab advocates for Wellpoint, and have been proud to work with the account team to help Wellpoint achieve their goals.
This marks the first commercial deployment of IBM Watson. This is a joint effort. IBM will develop the base IBM Watson for healthcare platform, and Wellpoint will then develop healthcare-specific solutions to run on this platform. Watson's ability to analyze the meaning and context of human language, and quickly process vast amounts of information to suggest options targeted to a patient's circumstances, can assist decision makers, such as physicians and nurses, in identifying the most likely diagnosis and treatment options for their patients.
Is this going to put doctors out of business? No. Physicians find it challenging to read and understand hundreds or thousands of pages of text, and put this into their practice. IBM Watson, on the other hand, can scan through hundred of millions of pages in just a few seconds to help answer a question or provide recommendations. Together, doctors armed with access to IBM Watson will be able to improve the quality and effectiveness of medical care.
From an insurance point of view, improving the quality of care will help reduce medical mistakes and malpractice lawsuits. This is a win-win for everyone except ambulance-chasing lawyers!
Last week, US President Barack Obama declared September 2011 as "National Preparedness Month". Here is an excerpt of the press release:
Whenever our Nation has been challenged, the American people have responded with faith, courage, and strength. This year, natural disasters have tested our response ability across all levels of government. Our thoughts and prayers are with those whose lives have been impacted by recent storms, and we will continue to stand with them in their time of need. This September also marks the 10th anniversary of the tragic events of September 11, 2001, which united our country both in our shared grief and in our determination to prevent future generations from experiencing similar devastation. Our Nation has weathered many hardships, but we have always pulled together as one Nation to help our neighbors prepare for, respond to, and recover from these extraordinary challenges.
In April of this year, a devastating series of tornadoes challenged our resilience and tested our resolve. In the weeks that followed, people from all walks of life throughout the Midwest and the South joined together to help affected towns recover and rebuild. In Joplin, Missouri, pickup trucks became ambulances, doors served as stretchers, and a university transformed itself into a hospital. Local businesses contributed by using trucks to ship donations, or by rushing food to those in need. Disability community leaders worked side-by-side with emergency managers to ensure that survivors with disabilities were fully included in relief and recovery efforts. These stories reveal what we can accomplish through readiness and collaboration, and underscore that in America, no problem is too hard and no challenge is too great.
Preparedness is a shared responsibility, and my Administration is dedicated to implementing a "whole community" approach to disaster response. This requires collaboration at all levels of government, and with America's private and nonprofit sectors. Individuals also play a vital role in securing our country. The National Preparedness Month Coalition gives everyone the chance to join together and share information across the United States. Americans can also support volunteer programs through www.Serve.gov, or find tools to prepare for any emergency by visiting the Federal Emergency Management Agency's Ready Campaign website at [www.Ready.gov] or [www.Listo.gov].
In the last few days, we have been tested once again by Hurricane Irene. While affected communities in many States rebuild, we remember that preparedness is essential. Although we cannot always know when and where a disaster will hit, we can ensure we are ready to respond. Together, we can equip our families and communities to be resilient through times of hardship and to respond to adversity in the same way America always has -- by picking ourselves up and continuing the task of keeping our country strong and safe.
NOW, THEREFORE, I, BARACK OBAMA, President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim September 2011 as National Preparedness Month. I encourage all Americans to recognize the importance of preparedness and observe this month by working together to enhance our national security, resilience, and readiness.
IBM has several webinars to help you prepare for upcoming disasters.
Today, September 8, at 4pm EDT, IBM is hosting a [CloudChat on Business Resilience] will focus on resiliency and continuity in the cloud—a timely topic considering the recent weather events on the East Coast of the U.S. This chat will include Richard Cocchiara, IBM Distinguished Engineer and CTO, IBM Business Continuity and Resiliency Services (@RichCocchiara1) and Patrick Corcoran, Global Business Development, IBM Business Continuity and Resiliency Services (@PatCorcoranIBM).
Don't think you can afford Disaster Recovery planning? Next week, September 13, I will be joined with a few other experts on freeing up much needed funds from your tight IT budget, by being more efficient. The Webinar [Taming Data Growth Made Easy] is part of IBM's "IT Budget Killer" series.
Lastly, on September 21, IBM will have the Webinar [Planning for Disaster Recovery in a Power Environment: Best Practices to Protect Your Data]. This will cover principal lessons learned from disasters like Hurricane Katrina and the World Trade Center, local and regional considerations for Disaster Recovery Planning, planning Recovery Time Objectives (RTOs), and best practices for automation, mirroring and multiple Site Operational Efficiencies. A customer case study from University of Rochester Medical Center (URMC) will help reinforce the concepts, with a discussion on how a major hospital ensures Business Continuity via Contingency Planning using IBM Power Systems. The speakers in clude Steve Finnes, World Wide Offering Manager for IBM Power Systems, Vic Peltz, Consulting IT Architect for WW Business Continuance Technical Marketing, and Rick Haverty, Director of IT Infrastructure at University of Rochester Medical Center (URMC).
Hopefully, you will find these webinars useful and informative!
We had our first "Future of IT Storage" Lunch-and-Learn here in Indianapolis, IN. We held it at the [Harry & Izzy's Restaurant], which looks like it has been in business for quite a while, but actually was only started four years ago. It is the sister restaurant for St. Elmo's next door which has been running since 1902, so it maintains a sense of that heritage, but with a bit more casual atmosphere.
Please note that in the wake of Hurricane Irene, the [Burlington, MA (Boston Area) event] has been postponed, probably to October or November. We have already notified all the people who signed up, but in case you planned just to show up, I wanted to let you know here in this blog.
Special thanks to Karen Harrison and Kerry Ingram for their help in setting up this event! Also a shout-out to Leanna and Amy, our two waitresses who served us today!
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.
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.
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.
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.

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.
After the amount of flack Jon Toigo had to endure for not giving advanced notice to his upcoming Webcast, I thought I would better remind people about my own Webinar that is happening next Tuesday, August 23.
So here's the scoop, next Tuesday I will be presenting [The Future of Storage], August 23, 1pm to 2pm EDT. You can register to attend at the [Infoboom Registration Page]. Infoboom is a social community for business and IT leaders of small and midsize businesses brought to you by IBM.
But that's not all! After the webinar, I will then travel to various cities for face-to-face lectures. Here are the first two:
September 7 - Indianapolis
September 8 - Boston area
If you are near either of these two locations, contact your local IBM storage specialist or IBM business partner to participate.
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.
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.
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!

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.
(FTC Disclosure: I do not work or have any financial investments in ENC Security Systems. ENC Security Systems did not paid me to mention them on this blog. Their mention in this blog is not an endorsement of either their company or any of their products. Information about EncryptStick was based solely on publicly available information and my own personal experiences. My friends at ENC Security Systems provided me a full-version pre-loaded stick for this review.)
The EncryptStick software comes in two flavors, a free/trial version, and the full/paid version. The free trial version has [limits on capacity and time] but provides enough glimpse of the product to decide before you buy the full version. You can download the software yourself and put in on your own USB device, or purchase the pre-loaded stick that comes with the full-version license.
Whichever you choose, the EncryptStick offers three nice protection features:
Encryption for data organized in "storage vaults", which can be either on the stick itself, or on any other machine the stick is connected to. That is a nice feature, because you are not limited to the capacity of the USB stick.
Encrypted password list for all your websites and programs.
A secure browser, that prevents any key-logging or malware that might be on the host Windows machine.
I have tried out all three functions and everything works as advertised. However, there is always room for improvement, so here are my suggestions.
The first problem is that the pre-loaded stick looks like it is worth a million dollars. It is in a shiny bronze color with "EncryptStick" emblazoned on it. This is NOT subtle advertising! This 8GB capacity stick looks like it would be worth stealing solely on being a nice piece of jewelry, and then the added bonus that there might be "valuable secrets" just makes that possibility even more likely.
If you want to keep your information secure, it would help to have "plausible deniability" that there is nothing of value on a stick. Either have some corporate logo on it, of have the stick look like a cute animal, like these pig or chicken USB sticks.
It reminds me how the first Apple iPod's were in bright [Mug-me White]. I use black headphones with my black iPod to avoid this problem.
Of course, you can always install the downloadable version of EncryptStick software onto a less conspicuous stick if you are concerned about theft. The full/paid version of EncryptStick offers an option for "lost key recovery" which would allow you to backup the contents of the stick and be able to retrieve them on a newly purchased stick in the event your first one is lost or stolen.
Imagine how "unlucky" I felt when I notice that I had lost my "rabbits feet" on this cute animal-themed USB stick.
I sense trouble for losing the cap on my EncryptStick as well. This might seem trivial, but is a pet-peeve of mine that USB sticks should plan for this. Not only is there nothing to keep the cap on (it slides on and off quite smoothly), but there is no loop to attach the cap to anything if you wanted to.
Since then, I got smart and try to look for ways to keep the cap connected. Some designs, like this IBM-logoed stick shown above, just rotate around an axle, giving you access when you need it, and protection when it is folded closed.
Alternatively, get a little chain that allows you to attach the cap to the main stick. In the case of the pig and chicken, the memory section had a hole pre-drilled and a chain to put through it. I drilled an extra hole in the cap section of each USB stick, and connected the chain through both pieces.
(Warning: Kids, be sure to ask for assistance from your parents before using any power tools on small plastic objects.)
The EncryptStick can run on either Microsoft Windows or Mac OS. The instructions indicate that you can install both versions of download software onto a single stick, so why not do that for the pre-loaded full version? The stick I have had only the Windows version pre-loaded. I don't know if the Windows and Mac OS versions can unlock the same "storage vaults" on the stick.
Certainly, I have been to many companies where either everyone runs Windows or everyone runs Mac OS. If the primary target audience is to use this stick at work in one of those places, then no changes are required. However, at IBM, we have employees using Windows, Mac OS and Linux. In my case, I have all three! Ideally, I would like a version of EncryptStick that I could take on trips with me that would allow me to use it regardless of the Operating System I encountered.
Since there isn't a Linux-version of EncryptStick software, I decided to modify my stick to support booting Linux. I am finding more and more Linux kiosks when I travel, especially at airports and high-traffic locations, so having a stick that works both in Windows or Linux would be useful. Here are some suggestions if you want to try this at home:
Use fdisk to change the FAT32 partition type from "b" to "c". Apparently, Grub2 requires type "c", but the pre-loaded EncryptStick was set to "b". The Windows version of EncryptStick> seems to work fine in either mode, so this is a harmless change.
Install Grub2 with "grub-install" from a working Linux system.
Once Grub2 is installed, you can boot ISO images of various Linux Rescue CDs, like [PartedMagic] which includes the open-source [TrueCrypt] encryption software that you could use for Linux purposes.
This USB stick could also be used to help repair a damaged or compromised Windows system. Consider installing [Ophcrack] or [Avira].
Certainly, 8GB is big enough to run a full Linux distribution. The latest 32-bit version of [Ubuntu] could run on any 32-bit or 64-bit Intel or AMD x86 machine, and have enough room to store an [encrypted home directory].
Since the stick is formatted FAT32, you should be able to run your original Windows or Mac OS version of EncryptStick with these changes.
Depending on where you are, you may not have the luxury to reboot a system from the USB memory stick. Certainly, this may require changes to the boot sequence in the BIOS and/or hitting the right keys at the right time during the boot sequence. I have been to some "Internet Cafes" that frown on this, or have blocked this altogether, forcing you to boot only from the hard drive.
Well, those are my suggestions. Whether you go on a trip with or without your laptop, it can't hurt to take this EncryptStick along. If you get a virus on your laptop, or have your laptop stolen, then it could be handy to have around. If you don't bring your laptop, you can use this at Internet cafes, hotel business centers, libraries, or other places where public computers are available.
