First day of the [IBM System Storage Technical University 2011] continued with more keynote sessions.
- Jim Rymarczyk
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.
- Clouds, such as IBM's [Smart Cloud Enterprise]
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 Barrera
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:
- Data Analytics
- Business Logic/Apps
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.

There were several break-out sessions on the second day of the [IBM System Storage Technical University 2011] related to Cloud Storage.
- Storage for Cloud Computing
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.
- SONAS and the Smart Business Storage Cloud
This is a presentation I often give at the [IBM Executive Briefing Center] in Tucson, Arizona. I cover the following points:
- IBM positioning between its two strategic NAS products: N series and SONAS
- The history of SONAS, from Storage Tank and SAN File System to the Scale-out File Services offering
- How SONAS is designed differently than N series GX Cluster mode and other mount-point aggregators
- Independent Scaling of performance and capacity, allowing companies to design a solution that fits their particular workload characteristics
- World Record Performance results for a moderately-sized SONAS deployment, for a single file system entirely on spinning disk, based on SPECsfs2008 benchmark
- IBM's Smart Business Storage Cloud, which combines the base SONAS product with IBM services to offer unique solutions optimized for specific industries, clients and workloads
These sessions served as a preview for later presentations in the week that got into more detail on SONAS specifically.

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.
To help people understand these concepts, IBM developed the [Thinking Worlds Player] game.
- Managing your Data with Policies on SONAS
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
- content distribution
- file production/rendering
- high performance computing, research and business analytics
- "Cheap and Deep" archive
- worldwide information exchange and geographically distant collaboration
- cloud hosting
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.

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.)
Are there any plans to improve the use of BRMS [Backup Recovery and Media Services for IBM i
] with [Tivoli Storage Manager (TSM)
It should be against the law to connect these two together. IBM has no plans to make any further improvements.
When will [IBM BladeCenter S
] support 2.5-inch drives?
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?
IBM introduced the [Tivoli Storage Productivity Center for Disk Midrange Edition (MRE)] to help address the cost when Small and Medium-sized Businesses managing SVC, Storwize V7000, DS5000 and DS3000 disk systems.
What is the adoption rate of IBM Easy Tier?
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).
What ever happened to IBM [Grid Medical Archive Solution (GMAS)
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.

Continuing my week in Washington DC for the annual [2010 System Storage Technical University], I presented a session on Storage for the Green Data Center, and attended a System x session on Greening the Data Center. Since they were related, I thought I would cover both in this post.
- Storage for the Green Data Center
I presented this topic in four general categories:
- Drivers and Metrics - I explained the three key drivers for consuming less energy, and the two key metrics: Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCiE).
- Storage Technologies - I compared the four key storage media types: Solid State Drives (SSD), high-speed (15K RPM) FC and SAS hard disk, slower (7200 RPM) SATA disk, and tape. I had comparison slides that showed how IBM disk was more energy efficient than competition, for example DS8700 consumes less energy than EMC Symmetrix when compared with the exact same number and type of physical drives. Likewise, IBM LTO-5 and TS1130 tape drives consume less energy than comparable HP or Oracle/Sun tape drives.
- Integrated Systems - IBM combines multiple storage tiers in a set of integrated systems managed by smart software. For example, the IBM DS8700 offers [Easy Tier] to offer smart data placement and movement across Solid-State drives and spinning disk. I also covered several blended disk-and-tape solutions, such as the Information Archive and SONAS.
- Actions and Next Steps - I wrapped up the talk with actions that data center managers can take to help them be more energy efficient, from deploying the IBM Rear Door Heat Exchanger, or improving the management of their data.
- Greening of the Data Center
Janet Beaver, IBM Senior Manager of Americas Group facilities for Infrastructure and Facilities, presented on IBM's success in becoming more energy efficient. The price of electricity has gone up 10 percent per year, and in some locations, 30 percent. For every 1 Watt used by IT equipment, there are an additional 27 Watts for power, cooling and other uses to keep the IT equipment comfortable. At IBM, data centers represent only 6 percent of total floor space, but 45 percent of all energy consumption. Janet covered two specific data centers, Boulder and Raleigh.
At Boulder, IBM keeps 48 hours reserve of gasoline (to generate electricity in case of outage from the power company) and 48 hours of chilled water. Many power outages are less than 10 minutes, which can easily be handled by the UPS systems. At least 25 percent of the Computer Room Air Conditioners (CRAC) are also on UPS as well, so that there is some cooling during those minutes, within the ASHRAE guidelines of 72-80 degrees Fahrenheit. Since gasoline gets stale, IBM runs the generators once a month, which serves as a monthly test of the system, and clears out the lines to make room for fresh fuel.
The IBM Boulder data center is the largest in the company: 300,000 square feet (the equivalent of five football fields)! Because of its location in Colorado, IBM enjoys "free cooling" using outside air temperature 63 percent of the year, resulting in a PUE of 1.3 rating. Electricity is only 4.5 US cents per kWh. The center also uses 1 Million KwH per year of wind energy.
The Raleigh data center is only 100,000 Square feet, with a PUE 1.4 rating. The Raleigh area enjoys 44 percent "free cooling" and electricity costs at 5.7 US cents per kWh. The Leadership in Energy and Environmental Design [LEED] has been updated to certify data centers. The IBM Boulder data center has achieved LEED Silver certification, and IBM Raleigh data center has LEED Gold certification.
Free cooling, electricity costs, and disaster susceptibility are just three of the 25 criteria IBM uses to locate its data centers. In addition to the 7 data centers it manages for its own operations, and 5 data centers for web hosting, IBM manages over 400 data centers of other clients.
It seems that Green IT initiatives are more important to the storage-oriented attendees than the x86-oriented folks. I suspect that is because many System x servers are deployed in small and medium businesses that do not have data centers, per se.

Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.
What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.
How do I evaluate IBM storage solutions in regards to [PCI-DSS
Well, we are not lawyers, and some aspects of the PCI-DSS requirements are outside the storage realm. In March 2010, IBM was named ["Best Security Company"] by SC Magazine, and we have secure storage solutions for both disk and tape systems. IBM DS8000 and DS5000 series offer Full Disk Encryption (FDE) disk drives. IBM LTO-4/LTO-5 and TS1120/TS1130 tape drives meet FIPS requirements for encryption. We will provide you contact information on an encryption expert to address the other parts of your PCI-DSS specific concerns.
My telco will only offer FCIP routing for long-distance disk replication, but my CIO wants to use Fibre Channel routing over CWDM, what do I do?
IBM XIV, DS8000 and DS5000 all support FC-based long distance replication across CWDM. However, if you don't have dark fiber, and your telco won't provide this option, you may need to re-negotiate your options.
My DS4800 sometimes reboots repeatedly, what should I do.
This was a known problem with microcode level 760.28, it was detecting a failed drive. You need to replace the drive, and upgrade to the latest microcode.
Should I use VMware snapshots or DS5000 FlashCopy?
VMware snapshots are not free, you need to upgrade to the appropriate level of VMware to get this function, and it would be limited to your VMware data only. The advantage of DS5000 FlashCopy is that it applies to all of your operating systems and hypervisors in use, and eliminates the consumption of VMware overhead. It provides crash-consistent copies of your data. If your DS5000 disk system is dedicated to VMware, then you may want to compare costs versus trade-offs.
Any truth to the rumor that Fibre Channel protocol will be replaced by SAS?
SAS has some definite cost advantages, but is limited to 8 meters in length. Therefore, you will see more and more usage of SAS within storage devices, but outside the box, there will continue to be Fibre Channel, including FCP, FICON and FCoE. The Fibre Channel Industry Alliance [FCIA] has a healthy roadmap for 16 Gbps support and 20 Gbps interswitch link (ISL) connections.
What about Fibre Channel drives, are these going away?
We need to differentiate the connector from the drive itself. Manufacturers are able to produce 10K and 15K RPM drives with SAS instead of FC connectors. While many have suggested that a "Flash-and-Stash" approach of SSD+SATA would eliminate the need for high-speed drives, IBM predicts that there just won't be enough SSD produced to meet the performance needs of our clients over the next five years, so 15K RPM drives, more likely with SAS instead of FC connectors, will continue to be deployed for the next five years.
We'd like more advanced hands-on labs, and to have the certification exams be more product-specific rather than exams for midrange disk or enterprise disk that are too wide-ranging.
Ok, we will take that feedback to the conference organizers.
IBM Tivoli Storage Manager is focused on disaster recovery from tape, how do I incorporate remote disk replication.
This is IBM's Unified Recovery Management, based on the seven tiers of disaster recovery established in 1983 at GUIDE conference. You can combine local recovery with FastBack, data center server recovery with TSM and FlashCopy manager, and combine that with IBM Tivoli Storage Productivity Center for Replication (TPC-R), GDOC and GDPS to manage disk replication across business continuity/disaster recovery (BC/DR) locations.
IBM Tivoli Storage Productivity Center for Replication only manages the LUNs, what about server failover and mapping the new servers to the replicated LUNs?
There are seven tiers of disaster recovery. The sixth tier is to manage the storage replication only, as TPC-R does. The seventh tier adds full server and network failover. For that you need something like IBM GDPS or GDOC that adds this capability.
All of my other vendor kit has bold advertising, prominent lettering, neon lights, bright colors, but our IBM kit is just black, often not even identifying the specific make or model, just "IBM" or "IBM System Storage".
IBM has opted for simplified packaging and our sleek, signature "raven black" color, and pass these savings on to you.
Bring back the SHARK fins!
We will bring that feedback to our development team. ("Shark" was the codename for IBM's ESS 800 disk model. Fiberglass "fins" were made as promotional items and placed on top of ESS 800 disk systems to help "identify them" on the data center floor. Unfortunately, professional golfer [<a href="http://www.shark.com/">Greg Norman</a>] complained, so IBM discontinued the use of the codename back in 2005.)
Where is Infiniband?
Like SAS, Infiniband had limited distance, about 10 to 15 meters, which proved unusable for server-to-storage network connections across data center floorspace. However, there are now 150 meter optical cables available, and you will find Infiniband used in server-to-server communications and inside storage systems. IBM SONAS uses Infiniband today internally. IBM DCS9900 offers Infiniband host-attachment for HPC customers.
We need midrange storage for our mainframe please?
In addition to the IBM System Storage DS8000 series, the IBM SAN Volume Controller and IBM XIV are able to connect to Linux on System z mainframes.
We need "Do's and Don'ts" on which software to run with which hardware.
IBM [Redbooks] are a good source for that, and we prioritize our efforts based on all those cards and letters you send the IBM Redbooks team.
The new TPC v4 reporting tool requires a bit of a learning curve.
The new reporting tool, based on Eclipse's Business Intelligence Reporting Tool [BIRT], is now standardized across the most of the Tivoli portfolio. Check out the [Tivoli Common Reporting] community page for assistance.
An unfortunate side-effect of using server virtualization like VMware is that it worsens management and backup issues. We now have many guests on each blade server.
IBM is the leading reseller of VMware, and understands that VMware adds an added layer of complexity. Thankfully, IBM Tivoli Storage Manager backups uses a lightweight agent. IBM [System Director VMcontrol] can help you manage a variety of hypervisor environments.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.

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

With all the announcements we had in June, it is easy for some of the more subtle enhancements to get overlooked. While I was at Orlando for the IBM Edge conference, I was able to blog about some of the key featured announcements. Then, later, when I got back from Orlando to Tucson, I was able to then blog about [More IBM Storage Announcements]. For IBM's Scale-Out Network Attach Storage (SONAS), I had simply:
"SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports Gateway configurations that have the storage nodes connected to XIV or Storwize V7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients."
In my defense, IBM numbers its software releasees with version.release.modification, so 1.3.2 is Version 1, Release 3, Modification 2. Generally, modification announcements don't get much attention. The big announcement for v1.3.0 of SONAS happened last October, see my blog post [October 2011 Announcements - Part I] or
the nice summary post [IBM Scale-out Network Attached Storage 1.3.0] from fellow blogger Roger Luethy.
Here is a diagram showing the three configurations of SONAS.
I have covered the SONAS Appliance model in depth in previous blogs, with options for fast and slow disk speeds, choice of RAID protection levels, a collection of enterprise-class software features provided at no additional charge, and interfaces to support a variety of third party backup and anti-virus checking software.
The basics haven't changed. The SONAS appliance consists of 2 to 32 interface nodes, 2 to 60 storage nodes, and up to 7,200 disk drives. The maximum configuration takes up 17 frames and holds 21.6PB of raw disk capacity, which is about 17PB usable space when RAID6 is configured. An interface nodes has one or two hex-core processors with up to 144GB of RAM to offer up to 3.5GB/sec performance each. This makes IBM SONAS the fastest performing and most scalable disk system in IBM's System Storage product line.
I thought I would go a bit deeper on the gateway models. These models support up to ten storage nodes, organized in pairs. The key difference is that instead of internal disk controllers, the storage nodes connect to external disk systems. There is enough space in the base SONAS rack to hold up to six interface nodes, or you can add a second rack if you need more interface nodes for increased performance.
- SONAS with XIV gateway
XIV offers a clever approach to storage that allows for incredibly fast access to data on relatively slow 7200 RPM drives. By scattering data across all drives and taking advantage of parallel processing, rebuild times for a failed 3TB drive are less than 75 minutes. Compare that to typical rebuild times for 3TB drives that could take as much as 9-10 hours under active I/O loads!
In the configuration, each pair of storage nodes can connect to external SAN Fabric switches that then connect to one or two XIV storage systems. How simple is that? These can be the original XIV systems that support 1TB and 2TB drives, or the new XIV Gen3 systems that support 400GB Solid-state drives (SSD) and 3TB spinning disk drives. In both cases, you can acquire additional storage capacity as little as 12 drives at a time (one XIV module holds 12 drives).
The maximum configuration of ten XIV boxes could hold 1,800 drives. At 3TB drive per drive, that would be 2.4PB usable capacity.
The SONAS with XIV gateway does not require the XIV devices to be dedicated for SONAS purposes. Rather, you can assign some XIV storage space for the SONAS, and the rest is available for other servers. In this manner, SONAS just looks like another set of Linux-based servers to the XIV storage system. This in effect gives you "Unified Storage", with a full complement of NAS protocols from the SONAS side (NFS, CIFS, FTP, HTTPS, SCP) as well as block-based protocols directly from the XIV (FCP, iSCSI).
- SONAS with Storwize V7000 gateway
The other gateway offering is the SONAS with Storwize V7000. Like the SONAS with XIV gateway model, you connect a pair of SONAS storage nodes to 1 or 2 Storwize V7000 disk systems. However, you do not need a SAN Fabric switch in between. You can instead connect the SONAS storage nodes directly to the Storwize V7000 control enclosures.
To acquire additional storage capacity, you can purchase a single drive at a time. That's right. Not 12 drives, or 60 drives, at a time, but one at a time. The Storwize V7000 supports a wide range of SSD, SAS and NL-SAS drives at different sizes, speeds and capacities. The drives can be configured into various RAID protection levels: RAID 0, 1, 3, 5, 6 and 10.
Each Storwize V7000 control enclosure can have up to nine expansion drawers. If you choose the 2.5-inch 24-bay models, you can have up to 480 drives per storage node pair, for a total of 2,400 drives. If you choose the 3.5-inch 12-bay models, you can have up to 240 drives per node pair, 1,200 drives total. At 3TB per drive, this could be 3.6PB of raw capacity. The usable PB would depend on which RAID level you selected. Of course, you don't have to limit yourself all to one size or the other. Feel free to mix 2.5-inch and 3.5-inch drawers to provide different storage pool capabilities.
All three SONAS configurations support Active Cloud Engine. This is a collection of features that differentiate SONAS from the other scale-out NAS wannabees in the marketplace:
- Policy-driven Data Placement -- Different files can be directed to different storage pools. You no longer have to associate certain file systems to certain storage technologies.
- High-speed Scan Engine -- SONAS can scan 10 million files per minute, per node. These scans can be used to drive data migration, backups, expirations, or replications, for example. It is over 100 times faster than traditional walk-the-directory-tree approaches employed by other NAS solutions.
- Policy-driven Migration -- You can migrate files from one storage pool to another, based on age, days since last reference, size, and other criteria. The files can be moved from disk to disk, or move out of SONAS and stored on external media, such as tape or a virtual tape library. A lot of data stored on NAS systems is dormant, with little or no likelihood of being looked at again. Why waste money keeping that kind of data on expensive disk? With SONAS, you can move those files to tape can save lots of money. The files are stubbed in the SONAS file system, so that an access request to a file will automatically trigger a recall to fetch the data from tape back to the SONAS system.
- Policy-driven Expiration -- SONAS can help you keep your system clean, by helping you decide what files should be deleted. This is especially useful for things like logs and traces that tend to just hang around until some deletes them manually.
- WAN Caching -- This allows one SONAS to act as a "Cloud Storage Gateway" for another SONAS at a remote location connected by Wide Area Network (WAN). Let's say your main data center has a large SONAS repository of files, and a small branch office has a smaller SONAS. This allows all locations to have a "Global" view of the all the interconnected SONAS systems, with a high-speed user experience for local LAN-based access to the most recent and frequently used files.
If you want to learn more, see the [IBM SONAS landing page]. Next week, I will be across the Pacific Ocean in [Taipei], to teach IBM Top Gun class to sales reps and IBM Business Partners. "Selling SONAS" will be one of the topics I will be covering!

Well, it's Tuesday again, and you know what that means... IBM announcements!
Last week, IBM had a big storage launch of various products, with the June 4 announcements at the IBM Edge 2012 conference. I provided highlights in my post [IBM Edge Announcements]. As promised, here are the rest of the announcements.
- SONAS v1.3.2
SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports "Gateway configurations" that have the storage nodes connected to XIV or Storwize v7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients.
- ProtecTIER appliances and gateways
IBM ProtecTIER line of data deduplication appliances and gateways add CIFS file system support. Rather than using OST or a VTL interface, you now have CIFS as a new option for host attach. Also, IBM introduces the new TS7620 Express model, with options for 5.4TB and 11TB in capacity, replacing the previous TS7610 entry level.
- LTFS Storage Manager
The Linear Tape File System (LTFS) allows files to be stored on tape cartridges in a manner that allows them to be mounted as file systems, much like a USB memory stick. The new LTFS Storage Manager software allows you to manage a collection of files across a set of cartridges, moving files from one cartridge to another, consolidating valid data onto fewer cartridges, and removing files no longer needed. This is sometimes referred to as "lifecycle management".
- Tape System Library Manager
When IBM first introduced the "shuttle" that allowed up to fifteen TS3500 tape libraries to be connected together into a single system, only HPSS customers could take advantage of this. Software was required to coordinate the movement of cartridges from one library to another. The new IBM Tape System Library Manager now offers an alternative to HPSS for coordinating this activity.
- DS8000 v6.3 microcode
IBM now offers 400GB solid-state drives. IBM's market leading support for Full Disk Encryption (FDE) is now extended to cover all drive speeds, from the slowest 7200RPM NL-SAS drives up to the fastest solid-state. IBM Easy Tier extends its super-easy implementation to work across all three of these tiers including encryption.
- Implementation Services
IBM now offers implementation services for IBM XIV Gen3 storage system, and the N series models 3220 and 3240.
This week I am on the road visiting various clients. Next week, Moscow Russia for the "Edge Comes to You" event!

Continuing my coverage of the 30th annual [Data Center Conference]. Here is a recap of the Monday afternoon sessions:
- IBM Watson and your Data Center
Steve Sams, IBM VP of Site and Facilities Services, cleverly used IBM Watson as a way to explain how analytics can be used to help manage your data center. Sadly, most of the people at my table missed the connection between IBM Watson and Analytics. How does answering a single trivia question in under three seconds relate to the ongoing operations of a data center? If you were similarly confused, take a peak at my series of IBM Watson blog posts:
- Devising a Cloud Computing Strategy
The analyst who presented this topic was probably the fastest-speaking Texan I have met. He covered various aspects of Cloud Computing that people need to consider. Why hasn't Cloud taken off sooner? The analyst feels that Cloud Computing wasn't ready for us, and we weren't ready for Cloud Computing. The fundamentals of Cloud Computing have not changed, but we as a society have. Now that many end users are comfortable consuming public cloud resources, from Facebook to Twitter to Gmail, they are beginning to ask for similar from their corporate IT.
- Legal issues - see this hour-long video, [Cloud Law & Order], which discusses legal issues related to Cloud Computing.
- Employee staffing - need to re-tool and re-train IT employees to start thinking of their IT as a service provider internally.
- Hybrid Cloud - rather than struggle choosing between private and public cloud methodologies, consider a combination of both.
- University of Rochester Medical Center (URMC) Cracks Code on Data Growth
Often times, the hour is split, 30 minutes of the sponsor talking about various products, followed by 30 minutes of the client giving a user experience. Instead, I decided to let the client speak for 45 minutes, and then I moderated the Q&A for the remaining 15 minutes. This revised format seemed to be well-received!
University of Rochester is in New York, about 60 miles east of Buffalo, and 90 miles from Toronto across Lake Ontario. Six years ago, Rick Haverty joined URMC as the Director of Infrastructure services, managing 130 of the 300 IT personnel at the Medical Center. I met Rick back in May, when he presented at the IBM [Storage Innovation Executive Summit] in New York City.
URMC has DS8000, DS5000, XIV, SONAS, Storwize V7000 and is in the process of deploying Storwize V7000 Unified. He presented how he has used these for continuous operations and high availability, while controlling storage growth and costs.
The Q&A was lively, focusing on how his team manages 1PB of disk storage with just four storage administrators, his choice of a "Vendor Neutral Archive" (VNA), and his experiences with integration.
This was a great afternoon, and I was glad to get all my speaking gigs done early in the week. I would like to thank Rick Haverty of URMC for doing a great job presenting this afternoon!
