Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.
What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.
How do I evaluate IBM storage solutions in regards to [PCI-DSS] requirements.
Well, we are not lawyers, and some aspects of the PCI-DSS requirements are outside the storage realm. In March 2010, IBM was named ["Best Security Company"] by SC Magazine, and we have secure storage solutions for both disk and tape systems. IBM DS8000 and DS5000 series offer Full Disk Encryption (FDE) disk drives. IBM LTO-4/LTO-5 and TS1120/TS1130 tape drives meet FIPS requirements for encryption. We will provide you contact information on an encryption expert to address the other parts of your PCI-DSS specific concerns.
My telco will only offer FCIP routing for long-distance disk replication, but my CIO wants to use Fibre Channel routing over CWDM, what do I do?
IBM XIV, DS8000 and DS5000 all support FC-based long distance replication across CWDM. However, if you don't have dark fiber, and your telco won't provide this option, you may need to re-negotiate your options.
My DS4800 sometimes reboots repeatedly, what should I do.
This was a known problem with microcode level 760.28, it was detecting a failed drive. You need to replace the drive, and upgrade to the latest microcode.
Should I use VMware snapshots or DS5000 FlashCopy?
VMware snapshots are not free, you need to upgrade to the appropriate level of VMware to get this function, and it would be limited to your VMware data only. The advantage of DS5000 FlashCopy is that it applies to all of your operating systems and hypervisors in use, and eliminates the consumption of VMware overhead. It provides crash-consistent copies of your data. If your DS5000 disk system is dedicated to VMware, then you may want to compare costs versus trade-offs.
Any truth to the rumor that Fibre Channel protocol will be replaced by SAS?
SAS has some definite cost advantages, but is limited to 8 meters in length. Therefore, you will see more and more usage of SAS within storage devices, but outside the box, there will continue to be Fibre Channel, including FCP, FICON and FCoE. The Fibre Channel Industry Alliance [FCIA] has a healthy roadmap for 16 Gbps support and 20 Gbps interswitch link (ISL) connections.
What about Fibre Channel drives, are these going away?
We need to differentiate the connector from the drive itself. Manufacturers are able to produce 10K and 15K RPM drives with SAS instead of FC connectors. While many have suggested that a "Flash-and-Stash" approach of SSD+SATA would eliminate the need for high-speed drives, IBM predicts that there just won't be enough SSD produced to meet the performance needs of our clients over the next five years, so 15K RPM drives, more likely with SAS instead of FC connectors, will continue to be deployed for the next five years.
We'd like more advanced hands-on labs, and to have the certification exams be more product-specific rather than exams for midrange disk or enterprise disk that are too wide-ranging.
Ok, we will take that feedback to the conference organizers.
IBM Tivoli Storage Manager is focused on disaster recovery from tape, how do I incorporate remote disk replication.
This is IBM's Unified Recovery Management, based on the seven tiers of disaster recovery established in 1983 at GUIDE conference. You can combine local recovery with FastBack, data center server recovery with TSM and FlashCopy manager, and combine that with IBM Tivoli Storage Productivity Center for Replication (TPC-R), GDOC and GDPS to manage disk replication across business continuity/disaster recovery (BC/DR) locations.
IBM Tivoli Storage Productivity Center for Replication only manages the LUNs, what about server failover and mapping the new servers to the replicated LUNs?
There are seven tiers of disaster recovery. The sixth tier is to manage the storage replication only, as TPC-R does. The seventh tier adds full server and network failover. For that you need something like IBM GDPS or GDOC that adds this capability.
All of my other vendor kit has bold advertising, prominent lettering, neon lights, bright colors, but our IBM kit is just black, often not even identifying the specific make or model, just "IBM" or "IBM System Storage".
IBM has opted for simplified packaging and our sleek, signature "raven black" color, and pass these savings on to you.
Bring back the SHARK fins!
We will bring that feedback to our development team. ("Shark" was the codename for IBM's ESS 800 disk model. Fiberglass "fins" were made as promotional items and placed on top of ESS 800 disk systems to help "identify them" on the data center floor. Unfortunately, professional golfer [<a href="http://www.shark.com/">Greg Norman</a>] complained, so IBM discontinued the use of the codename back in 2005.)
Where is Infiniband?
Like SAS, Infiniband had limited distance, about 10 to 15 meters, which proved unusable for server-to-storage network connections across data center floorspace. However, there are now 150 meter optical cables available, and you will find Infiniband used in server-to-server communications and inside storage systems. IBM SONAS uses Infiniband today internally. IBM DCS9900 offers Infiniband host-attachment for HPC customers.
We need midrange storage for our mainframe please?
In addition to the IBM System Storage DS8000 series, the IBM SAN Volume Controller and IBM XIV are able to connect to Linux on System z mainframes.
We need "Do's and Don'ts" on which software to run with which hardware.
IBM [Redbooks] are a good source for that, and we prioritize our efforts based on all those cards and letters you send the IBM Redbooks team.
The new TPC v4 reporting tool requires a bit of a learning curve.
The new reporting tool, based on Eclipse's Business Intelligence Reporting Tool [BIRT], is now standardized across the most of the Tivoli portfolio. Check out the [Tivoli Common Reporting] community page for assistance.
An unfortunate side-effect of using server virtualization like VMware is that it worsens management and backup issues. We now have many guests on each blade server.
IBM is the leading reseller of VMware, and understands that VMware adds an added layer of complexity. Thankfully, IBM Tivoli Storage Manager backups uses a lightweight agent. IBM [System Director VMcontrol] can help you manage a variety of hypervisor environments.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.
Continuing my romp through Australia and New Zealand, the last Storage Optimisation Breakfast of the week was Brisbane, which the locals here refer to as [Brisvegas], probably for all of the nightlife and casinos here.
The IBM office building is conveniently across the street from my hotel, the [Sofitel Brisbane]. The hotel also sits above central station, which allows quick transportation to the airport.
This time, we had a tag team of two people from James Cook University (JCU) to present their success story. First up was Kent Adams, the Director or Information Technology and Resources. JCU is recognized as one of the top 5 percent of Universities worldwide, and as a result, their data storage requirements are growing at 400 percent per year! Their latest purchase put out for RFP was for at least 40TB that could handle at least 20,000 IOPS. The winning solutions was an IBM XIV disk system.
Behind the scenes at all the events this week here in Australia were, from left to right, Natalie from GPJ Australia, the local subsidiary of the George P. Johnson events management we use in the states; Sonia Phillips, IBM Advisory Marketing Lead for Dynamic Infrastructure Optimisation and Cloud Computing, Demand Programs, for Australia and New Zealand; and Monika Lovgren, IBM Marketing and Execution Lead for Workload Optimised Systems for Australia.
The second speaker was Lee Askew, one of the Storage Administrators. Overall, the JCU team have been amazed at how well this box works. When they started it up, they expected to spend the next 24-36 hours formatting RAID ranks, but not with the XIV. It was ready in 2 minutes and they started provisioning storage right away. Their own tests to fail a drive found they can do a full rebuild to redundancy in 9 minutes. It took 8-36 hours on their previous disk array. Failing a full data module took only 75 minutes to bring back to redundancy.
After a long and tiring week, I was able to relax by walking through this beautiful King Edward park near the IBM building. This had a nice variety of plants and flowers, and with the surprise visit of a lizard about the length of my arm that crossed my path.
JCU also uses Asynchronous Mirror to replicate data to another XIV at distance. Again, as with all aspects of IBM XIV, the solution works as advertised. They are well positioned to grow from the 18,000 students they have today, to their target goal of 25,000 students they want to have by 2015.
Worldwide, IBM has done well with colleges and universities, and this was a great example of how partnering with IBM for your IT infrastructure can make a huge difference!
Wrapping up my seven-city romp through Australia and New Zealand, the final city was Canberra, which is the capital of Australia. As with Wellington, this meant many of the clients in the audience work in government agencies.
I had not taken any photos of Anna Wells, IBM Storage Sales Leader for ANZ, but I was able to find this caricature of her on a poster from an award she won within IBM.
I also did not have a picture of Robert, my videographer for this trip, who was always behind the camera himself.
The event went smoothly, just like the rest of them. Anna presented IBM's storage strategy and highlighted specific IBM storage solutions.
I had several emails asking if this event was called "Storage Optimisation Breakfast" because it was held in the mornings, or did we actually serve food at these events. The answer is we actually served food, a variation of the [Full English Breakfast], and most of the attendees gobbled it down while Anna spoke.
The fare was quite similar across all seven locations: scrambled or poached eggs, on toast or english muffin, ham/bacon/sausages, potatoes or mushrooms, and half of a baked tomato with bits of something toasted on top.
One morning, for a change, I decided instead to have a bowl of Weet-Bix cereal. Tasted like cardboard. I learned my lesson.
Next, we had Will Quodling, Manager of Infrastructure Operations, at Australia's Department of Innovation, Industry, Science and Research. The Department of Innovation, Industry, Science and Research consists of 3200 staff that strive to encourage the sustainable growth of Australian industries. The Department is committed to developing policies and delivering programs to provide lasting economic benefits ensuring Australia's competitive future, undertakes analysis, and provides services and advice to the business, science and research community. American President, Barack Obama, visited Australia and was interested in adopting a similar concept for the United States.
The department was looking to replace their existing IBM System Storage DS4800 disk systems with something more energy efficient. They selected IBM XIV storage system, with an expected savings of 10kW per year. They are able to run 800 VMware images and 150 VDI workstations using storage on one XIV, replicate the data to a second XIV at a remote location, and have a third XIV for their Web serving environment. They tested out both single drive and full module failures, and experienced better-than-expected rebuild times, with no impact to users, and no impact to performance.
After 17 days without a functioning government, Australia finally selected a prime minister. Her name is Julia Gillard, shown here. She won in part by promising to build a National Broadband Network (NBN) for the entire country, including the rural areas.
[Canberra] is an interesting town, a fully planned community designed in 1913 by Chicago's husband-and-wife architect team of Walter Burley Griffin and Marion Mahony Griffin. The location was selected as being half-way compromise between Australia's two largest cities, Sydney and Melbourne.
I would like to thank all the wonderful people in both Australia and New Zealand for making this a successful trip!
Continuing my post-week coverage of the [Data Center 2010 conference], Wednesday morning started with another keynote session, followed by some break-out sessions.
Realities of IT Investment
Tighter budgets mean more business decisions. Future investments will come from cost savings. The analysts report that 77 percent of IT decisions are made by CFOs. Most organizations are spending less now than back in 2008 before the recession.
How we innovate through IT is changing. In bad times, risk trumps return, but only 21 percent of the audience have a formal "risk calculation" as part of their purchase plans.
Divestment matters as much as investment. Reductions in complexity have the greatest long-term cost savings. Try to retire at least 20 percent of your applications next year. With the advent of Cloud Computing, companies might just retire it and go entirely with public cloud offerings. Note that this graph the years are different than the ones above, in groups of half-decade increments.
It is important to identify functional dependencies and link your IT risks to business outcomes. Focus on making costs visible, and re-think how you communicate IT performance measurements and their impact to business. Try to change the culture and mind-set so that projects are not referred to as "IT projects" focused on technology, but rather they are "business projects" focused on business results.
Moving to the Cloud
Richard Whitehead from Novell presented challenges in moving to Cloud Computing. There are risks and challenges managing multiple OS environments. Users should have full access to all IT resources they need to do their jobs. Computing should be secure, compliant, and portable. Here is the shift he sees from physical servers to virtual and cloud deployments, years 2010 to 2015:
Richard considers a "workload" as being the combination of the operating system, middleware, and application. He then defines "Business Service" as an appropriate combination of these workloads. For example, a business service that provides a particular report might involve a front-end application, talking through business logic workload server, talking to a back-end database workload server.
To address this challenge, Novell introduces "Intelligent Workload Management", called WorkloadIQ. This manages the lifecycle to build, secure, deploy, manage and measure each workload. Their motto was to take the mix of physical, virtual and cloud workloads all "make it work as one". IBM is a business partner with Novell, and I am a big fan of Novell's open-source solutions including SUSE Linux.
A Funny Thing Happened on the Way to the Cloud....
Bud Albers, CTO of Disney, shared their success in deploying their hybrid cloud infrastructure. Everyone recognizes the Disney brand for movies and theme parks, but may not aware that they also own ABC News and ESPN television, Travel cruises, virtual worlds, mobile sites, and deploy applications like Fantasy Football and Fantasy Fishing.
Two years ago, each Line of Business (LOB) owned their own servers, they were continually out of space, power and HVAC issues forced tactical build-outs of their datacenters. But in 2008, the answer to all questions was Cloud Computing, it slices and dices like something invented by [Ron Popeill], with no investment or IT staff required. However, continuing to ask the CFO for CAPEX to purchase assets that were only 1/7th used was not working out either. That's right, over 75 percent of their servers were running less than 15 percent CPU utilization.
The compromise was named "D*Cloud". Internal IT infrastructure would be positioned for Cloud Computing, by adopting server virtualization, implementing REST/SOAP interfaces, and replicating the success across their various Content Distribution Networks (CDN). Disney is no stranger to Open Source software, using Linux and PHP. Their [Open Source] web page shows tools available from Disney Animation studios.
At the half-way point, they had half their applications running virtualized on just 4 percent of their servers. Today, they run over 20 VMs per host and have 65 percent of their apps virtualized. Their target is 80 percent of their apps virtualized by 2014.
Bud used the analogy that public clouds will be the "gas stations" of the IT industry. People will choose the cheapest gas among nearby gas stations. By focusing on "Application management" rather than "VM instance management", Disney is able to seamlessly move applications as needed from private to public cloud platforms.
Their results? Disney is now averaging 40 percent CPU utilization across all servers. Bud feels they have achieved better scalability, better quality of service, and increased speed, all while saving money. Disney is spending less on IT now than in 2008,
UPMC Maximizes Storage Efficiency with IBM
Kevin Muha, UPMC Enterprise Architect & Technology Manager for Storage and Data Protection Services, was unable to present this in person, so Norm Protsman (IBM) presented Kevin's charts on the success at the University of Pittsburgh Medical Center [UPMC]. UPMC is Western Pennsylvania's largest employer, with roughly 50,000 employees across 20 hospitals, 400 doctors' offices and outpatient sites. They have frequently been rated one of the best hospitals in the US.
Their challenge was storage growth. Their storage environment had grown 328 percent over the past three years, to 1.6PB of disk and nearly 7 PB of physical tape. To address this, UPMC deployed four IBM TS7650G ProtecTIER gateways (2 clusters) and three XIV storage systems for their existing IBM Tivoli Storage Manager (TSM) environment. Since they were already using TSM over a Fibre Channel SAN, the implementation took only three days.
UPMC was backing up nearly 60TB per day, in a 15-hour back window. Their primary data is roughly 60 percent Oracle, with the rest being a mix of Microsoft Exchange, SQL Server, and unstructured data such as files and images.
Their results? TSM reclamation is 30 percent faster. Hardware footprint reduced from 9 tiles to 5. Over 50 percent reduction in recovery time for Oracle DB, and 20 percent reduction in recovery of SQL Server, Microsoft Exchange, and Epic Cache. They average 24:1 deduplication overall, which can be broken down by data category as follows:
29:1 Cerner Oracle
18:1 EPIC Cache
10:1 Microsoft SQL Server
8:1 Unstructured files
6:1 Microsoft Exchange
UPMC still has lots of LTO-4 tapes onsite and offsite from before the change-over, so the next phase planned is to implement "IP-based remote replication" between ProtecTIER gateways to a third data center at extended distance. The plan is to only replicate the backups of production data, and not replicate the backups of test/dev data.
Full VMware Vstorage API for Array Integration (VAAI). Back in 2008, VMware announced new vStorage APIs for its vSphere ESX hypervisor: vStorage API for Site Recovery Manager, vStorage API for Data Potection, vStorage API for Multipathing. Last July, VMware added a new API called vStorage API for Array Integration [VAAI] which offers three primitives:
Hardware-assisted Blocks zeroing. Sometimes referred to as "Write Same", this SCSI command will zero out a large section of blocks, presumably as part of a VMDK file. This can then be used to reclaim space on the XIV on thin-provisioned LUNs.
Hardware-assisted Copy. Make an XIV snapshot of data without any I/O on the server hardware.
Hardware-assisted locking. On mainframes, this is call Parallel Access Volumes (PAV). Instead of locking an entire LUN using standard SCSI reserve commands, this primitive allows an ESX host to lock just an individual block so as not to interfere with other hosts accessing other blocks on that same LUN.
Quality of Service (QoS) Performance Classes.
When XIV was first released, it treated all hosts and all data the same, even when deployed for a variety of different applications. This worked for some clients, such as [Medicare y Mucho Más]. They migrated their databases, file servers and email system from EMC CLARiiON to an IBM XIV Storage System. In conjunction with VMware, the XIV provides a highly flexible and scalable virtualized architecture, which enhances the company's business agility.
However, other clients were skeptical, and felt they needed additional "nobs" to prioritize different workloads. The new 10.2.4 microcode allows you to define four different "performance classes". This is like the door of a nightclub. All the regular people are waiting in a long line, but when a celebrity in a limo arrives, the bouncer unclips the cord, and lets the celebrity in. For each class, you provide IOPS and/or MB/sec targets, and the XIV manages to those goals. Performance classes are assigned to each host based on their value to the business.
Offline Initialization for Asynchronous Mirror.
Internally, we called this Truck Mode. Normally, when a customer decides to start using Asynchronous Mirror, they already have a lot of data at the primary location, and so there is a lot of data to send over to the new XIV box at the secondary location. This new feature allows the data to be dumped to tape at the primary location. Those tapes are shipped to the secondary location and restored on the empty XIV. The two XIV boxes are then connected for Asynchronous Mirroring, and checksums of each 64KB block are compared to determine what has changed at the primary during this "tape delivery time". This greatly reduces the time it takes for the two boxes to get past the initial synchronization phase.
IP-based Replication. When IBM first launched the Storwize V7000 last October, people commented that the one feature they felt missing was IP-based replication. Sure, we offered FCP-based replication as most other Enterprise-class disk systems offer today, but many midrange systems also offer IP-based repliation to reduce the need for expensive FCIP routers. [IBM Tivoli Storage FastBack for Storwize V7000] provides IP-based replication for Storwize V7000 systems.
Network Attached Storage
IBM announced two new models of the IBM System Storage N series. The midrange N6240 supports up to 600 drives, replacing the N6040 system. The entry-level N6210 supports up to 240 drives, and replaces the N3600 system. Details for both are available on the latest [data sheet].
IBM Real-Time Compression appliances work with all N series models to provide additional storage efficiency. Last October, I provided the [Product Name Decoder Ring] for the STN6500 and STN6800 models. The STN6500 supports 1 GbE ports, and the STN6800 supports 10GbE ports (or a mix of 10GbE and 1GbE, if you prefer). The IBM versions of these models were announced last December, but some people were on vacation and might have missed it. For more details of this, read the [Resources page], the [landing page], or [watch this video].
IBM System Storage DS3000 series
IBM System Storage [DS3524 Express DC and EXP3524 Express DC] models are powered with direct current (DC) rather than alternating current (AC). The DS3524 packs dual controllers and two dozen small-form factor (2.5 inch) drives in a compact 2U-high rack-optimized module. The EXP3524 provides addition disk capacity that can be attached to the DS3524 for expansion.
Large data centers, especially those in the Telecommunications Industry, receive AC from their power company, then store it in a large battery called an Uninterruptible Power Supply (UPS). For DC-powered equipment, they can run directly off this battery source, but for AC-powered equipment, the DC has to be converted back to AC, and some energy is lost in the conversion. Thus, having DC-powered equipment is more energy efficient, or "green", for the IT data center.
Whether you get the DC-powered or AC-powered models, both are NEBS-compliant and ETSI-compliant.
New Tape Drive Options for Autoloaders and Libraries
IBM System Storage [TS2900 Autoloader] is a compact 1U-high tape system that supports one LTO drive and up to 9 tape cartridges. The TS2900 can support either an LTO-3, LTO-4 or LTO-5 half-height drive.
IBM System Storage [TS3100 and TS3200 Tape Libraries] were also enhanced. The TS3100 can accomodate one full-height LTO drive, or two half-height drives, and hold up to 24 cartridges. The TS3200 offers twice as many drives and space for cartridges.
Dan Galvan, IBM VP of Marketing for Storage, was the next speaker. With 300 billion emails being sent per day, 4.6 billion cell phones in the world, and 26 million MRIs per year, there is going to be a huge demand for file-based storage. In fact, a recent study found that file-based storage will grow at 60 percent per year, compared to 15 percent growth for block-based storage.
Dan positioned IBM's Scale-out Network Attached Storage (SONAS) as the big "C:" drive for a company. SONAS offers a global namespace, a single point of management, with the ability to scale capacity and performance tailored for each environment.
The benefits of SONAS are great. We can consolidate dozens of smaller NAS filers, we can virtualize files across different storage pools, and increase overall efficiency.
Powering advanced genomic research to cure cancer
The next speaker was supposed to be Bill Pappas, Senior Enterprise Network Storage Architect, Research Informatics at [St. Jude Children’s Research Hospital]. Unfortunately, St. Jude is near the flooding of the Mississippi river, and he had to stay put. An IBM team was able to capture his thoughts on video that was shown on the big screen.
Thanks to the Human Genome project, St. Jude is able to cure people. They see 5700 patients per year, and have an impressive 70 percent cure rate. The first genetic scan took 10 years, now the technology allows a genome to be mapped in about a week. Having this genomic information is making vast strides in healthcare. It is the difference of fishing in a river, versus putting a wide net to catch all the fish in the Atlantic ocean all at once.
Recently, St. Jude migrated 250 TB of files from other NAS to an IBM SONAS solution. The SONAS can handle a mixed set of workloads, and allows internal movement of data from fast disk, to slower high-capacity disk, and then to tape. SONAS is one of the few storage systems that supports a blended disk-and-tape approach, which is ideal for the type of data captured by St. Jude.
IBM's own IT transformation
Pat Toole, IBM's CIO, presented the internal transformation of IBM's IT operations. He started in 2002 in the midst of IBM's effort to restructure its process and procedures. They identified four major data sources: employee data, client data, product data, and financial data. They put a focus to understand outcomes and set priorities.
The result? A 3-to-1 payback on CIO investments. This allowed IBM to go from server sprawl to consolidated pooling of resources with the right levels of integration. In 1997, IBM had 15,000 different applications running across 155 separate datacenters. Today, they have reduced this down to 4,500 applications and 7 datacenters. Their goal is to reduce down to 2,225 applications by 2015. Of these, only 250 are mission critical.
Pat's priorities today: server and storage virtualization, IT service management, cloud computing, and data-centered consolidation. IBM runs its corporate business on the following amount of data:
9 PB of block-based storage, SVC and XIV
1 PB of file-based storage, SONAS
15 PB of tape for backup and archive
Pat indicated that this environment is growing 25 percent per year, and that an additional 70-85 PB relates to other parts of the business.
By taking this focused approach, IBM was able to increase storage utilization from 50 to 90 percent, and to cut storage costs by 50 percent. This was done through thin provisioning, storage virtualization and pooling.
Looking forward to the future, Pat sees the following challenges: (a) that 120,000 IBM employees have smart phones and want to connect them to IBM's internal systems; (b) the increase in social media; and (c) the use of business analytics.
After the last session, people gathered in the "Hall of the Universe" for the evening reception, featuring food, drinks and live music. It was a great day. I got to meet several bloggers in person, and their feedback was that this was a very blogger-friendly event. Bloggers were given the same level of access as corporate executives and industry analysts.
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.
Did IBM XIV force EMC's hand to announce VMAXe? Let's take a stroll down memory lane.
In 2008, IBM XIV showed the world that it could ship a Tier-1, high-end, enterprise-class system using commodity parts. Technically, prior to its acquisition by IBM, the XIV team had boxes out in production since 2005. EMC incorrectly argued this announcement meant the death of the IBM DS8000. Just because EMC was unable to figure out how to have more than one high-end disk product, doesn't mean IBM or other storage vendors were equally challenged. Both IBM XIV and DS8000 are Tier-1, high-end, enterprise-class storage systems, as are the IBM N series N7900 and the IBM Scale-Out Network Attached Storage (SONAS).
In April 2009, EMC followed IBM's lead with their own V-Max system, based on Symmetrix Engenuity code, but on commodity x86 processors. Nobody at EMC suggested that the V-Max meant the death of their other Symmetrix box, the DMX-4, which means that EMC proved to themselves that a storage vendor could offer multiple high-end disk systems. Hitachi Data Systems (HDS) would later offer the VSP, which also includes some commodity hardware as well.
In July 2009, analysts at International Technology Group published their TCO findings that IBM XIV was 63 percent less expensive than EMC V-Max, in a whitepaper titled [COST/BENEFIT CASE
FOR IBM XIV STORAGE SYSTEM Comparing Costs for IBM XIV and EMC V-Max Systems]. Not surprisingly, EMC cried foul, feeling that EMC V-Max had not yet been successful in the field, it was too soon to compare newly minted EMC gear with a mature product like XIV that had been in production accounts for several years. Big companies like to wait for "Generation 1" of any new product to mature a bit before they purchase.
To compete against IBM XIV's very low TCO, EMC was forced to either deeply discount their Symmetrix, or counter-offer with lower-cost CLARiiON, their midrange disk offering. An ex-EMCer that now works for IBM on the XIV sales team put it in EMC terms -- "the IBM XIV provides a Symmetrix-like product at CLARiiON-like prices."
(Note: Somewhere in 2010, EMC dropped the hyphen, changing the name from V-Max to VMAX. I didn't see this formally announced anywhere, but it seems that the new spelling is the officially correct usage. A common marketing rule is that you should only rename failed products, so perhaps dropping the hyphen was EMC's way of preventing people from searching older reviews of the V-Max product.)
This month, IBM introduced the IBM XIV Gen3 model 114. The analysts at ITG updated their analysis, as there are now more customers that have either or both products, to provide a more thorough comparison. Their latest whitepaper, titled [Cost/Benefit Case for IBM XIV Systems: Comparing Cost
Structures for IBM XIV and EMC VMAX Systems], shows that IBM maintains its substantial cost savings advantage, representing 69 percent less Total Cost of Ownership (TCO) than EMC, on average, over the course of three years.
In response, EMC announced its new VMAXe, following the naming convention EMC established for VNX and VNXe. Customers cannot upgrade VNXe to VNX, nor VMAXe to VMAX, so at least EMC was consistent in that regard. Like the IBM XIV and XIV Gen3, the new EMC VMAXe eliminated "unnecessary distractions" like CKD volumes and FICON attachment needed for the IBM z/OS operating system on IBM System z mainframes. Fellow blogger Barry Burke from EMC explains everything about the VMAXe in his blog post [a big thing in a small package].
So, you have to wonder, did IBM XIV force EMC's hand into offering this new VMAXe storage unit? Surely, EMC sales reps will continue to lead with the more profitable DMX-4 or VMAX, and then only offer the VMAXe when the prospective customer mentions that the IBM XIV Gen3 is 69 percent less expensive. I haven't seen any list or street prices for the VMAXe yet, but I suspect it is less expensive than VMAX, on a dollar-per-GB basis, so that EMC will not have to discount it as much to compete against IBM.
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.
This week, IBM made over a dozen announcements related to IBM storage products. Here is part 2 of my overview:
IBM System Storage® DS8000 series microcode
One of the advantages of acquiring XIV as IBM's other high-end disk system, is that it allows the DS8000 team to focus on the IBM i and z/OS operating systems. As a result, IBM DS8000 has over half the mainframe-attach market share.
For both the DS8700 and DS8800 models, IBM Easy Tier now support sub-LUN automated tiering across three storage tiers: Solid-State Drives, high-performance spinning disk drives (15K and 10K RPM), and high-capacity disk drives (7200 RPM).
For System z customers, the latest DS8000 microcode has synergy with z/OS and GDPS, now supporting 4x larger EAV volumes, faster high-performance FICON (zHPF), and Workload Manager (WLM) integration with the I/O Priority Manager. IBM has a world record SAP performance of 59 million account postings per hour. DB2 v10 for z/OS queries were measured at 11x faster using the new zHPF feature.
IBM System Storage® DS8800 systems
On the hardware side, the DS8800 now supports a fourth frame to hold a total over 1,500 disk drives. Yes, we have customers that three frames wasn't enough, and they wanted more.
IBM is now also offering new drive options. Small Form Factor (2.5 inch) drives now include 300GB 15K RPM drives, and a 900GB 10K RPM drives. But wait! There's more! The DS8800 is no longer a SFF-only box, it now allows for mixing in Large form factor (3.5 inch) drives, starting with the 3TB NL-SAS 7200 RPM drive.
IBM XIV® Storage System Gen3
We announced the XIV Gen3 already, but we have two enhancements.
First, we now offer a model based entirely on 3TB NL-SAS drives. If you are thinking, what IBM is going to put 3TB drives into everything? Yup. Once we go through all the pain and suffering of qualifying a drive, we make sure we get our money's worth!
Secondly, we have now an iPad application to manage the XIV. This has nothing to do with Apple CEO Steve Jobs passing away last week, it was merely coincidence.
IBM Real-time Compression Appliances™ STN6500 and STN6800 V3.8
The latest software for RtCA now supports Microsoft SMB v2, and enhanced reporting so that storage admins know exactly the benefits of the compression ratios of different file extensions.
IBM System Storage EXP2500 Express®
The EXP2500 is for direct-attach situations, like the IBM BladeCenter. IBM adds LFF 3.5-inch 3TB NL-SAS drives, SFF 2.5-inch 300GB 15K RPM SAS drives, and 900GB 7200 RPM NL-SAS drives.
My colleague Curtis Neal refers to these as "B.F.D" announcements, which of course stands for Bigger, Faster, Denser!
An exciting new addition to the IBM storage line, the Storwize V7000 is a very versatile and solid choice as a midrange storage device. This session will cover a technical overview of the controller as well as its positioning within the overall IBM storage line.
xST04 - XIV Implementation, Migration and Optimization
Attend this session to learn how to integrate the IBM XIV Storage System in your IT environment. After this session, you should understand where the IBM XIV Storage system fits, and understand how to take full advantage of the performance capabilities of XIV Storage by using the massive parallelism of its grid architecture. You will learn how to migrate data onto the XIV and hear about real world client experiences.
xST05 - IBM's Storage Strategy in the Smarter Computing Era
Want to understand IBM's storage strategy better? This session will cover the three key themes of IBM's Smarter Computing initiative: Big Data, Optimized Systems, and Cloud. IBM System Storage strategy has been aligned to meet the storage efficiency, data protection and retention required to meet these challenges.
IBM offers encryption in a variety of ways. Data can be encrypted on the server, in the SAN switch, or on the disk or tape drive. This session will explain how encryption works, and explain the pros and cons with each encryption option.
sAC01 - IBM Information Archive for email, Files and eDiscovery
IBM has focused on data protection and retention, and the IBM Information Archive is the ideal product to achieve it. Come to this session to discuss archive solutions, compliance regulations, and support for full-text indexing and eDiscovery to support litigation.
sGE04 - IBM's Storage Strategy in the Smarter Computing Era
Want to understand IBM's storage strategy better? This session will cover the three key themes of IBM's Smarter Computing initiative: Big Data, Optimized Systems, and Cloud. IBM System Storage strategy has been aligned to meet the storage efficiency, data protection and retention required to meet these challenges.
sSM03 - IBM Tivoli Storage Productivity Center – Overview and Update
IBM's latest release of IBM Tivoli Storage Productivity Center is v4.2.2, a storage resource management tool that manages both IBM and non-IBM storage devices, including disk systems, tape libraries, and SAN switches. This session will give an overview of the various components of Tivoli Storage Productivity Center and provide an update on what's new in this product.
sSN06 - SONAS and the Smart Business Storage Cloud (SBSC)
Confused over IBM's Cloud strategy? Trying to figure out how IBM Storage plays in private, hybrid or public cloud offerings? This session will cover both the SONAS integrated appliance and the Smart Business Storage Cloud customized solution, and will review available storage services on the IBM Cloud.
sTA01 - Tape Storage Reinvented: What's New and Exciting in the Tape World?
This very informative session will keep you up to date with the latest tape developments. These include the TS3500 tape library connector Model SC1 (Shuttle). The shuttle enables extreme scalability of over 300,000 tape cartridges in a single library image by interconnecting multiple tape libraries with a unique, high speed transport system. The world's fastest tape drive, the TS1140 3592-E07, will also be presented. The performance and functionality of the new TS1140 as well as the new 4TB tape media will be discussed. Also, the IBM System Storage Linear Tape File System (LTFS), including the Library Edition, will be presented. LTFS allows a disk-like, drag-and-drop interface for tape. This is a not-to-be-missed session for all you tape lovers out there!
In December, I will be going to Gartner's Data Center Conference in Las Vegas, but the agenda has not been finalized, so I will save that for another post.
Special thanks to Anthony Vandewerdt, who sent me his version of this presentation that he planned to present in Australia next week. I "smartened it up" (or whatever the appropriate phrase is the opposite of "dumbed it down") for the technical audience.
Recovery procedures for single and double drive failures. A double drive failure on an XIV typically involves less recovery effort than traditional RAID5-based disk systems, and in many cases results in no data loss whatsoever. I provided details on this in my blog post [Double Drive Failure Debunked: XIV Two Years Later], so no need to repeat myself here.
Replacing the Automatic Transfer Switch (ATS) non-disruptively. To support either single-phase and triple-phase power sources, the XIV uses an ATS to take two independent power feeds, and distribute this out to the three Uninterruptible Power Supplies (UPS).
Built-in Migration capability to copy data off other disk systems over to the XIV.
Configuring Synchronous and Asynchronous mirroring using either the Fibre Channel or Internet Protocol ports.
Optimizing the use of XIV for VMware, AIX and other operating systems.
The IBM XIV Storage System is quite popular in New Zealand, with four times more boxes sold per capita than the other countries in the Asia Pacific region. I covered both the A14 model as well as the new Gen3 model.
Business Continuity/Disaster Recovery (BC/DR) Update: Lessons, Planning, Solutions
My colleague Vic Peltz from IBM Almaden presented on lessons learned from Hurricane Katrina and various other natural disasters. Unlike tradtional presentations the focus on technology, Vic took a different approach, focusing on people and procedures. I was here last year when the earthquake hit Christchurch on the south island, so I was well aware that BC/DR was top of mind for many of the attendees. Throughout this week, I have felt tremors, and many of the locals told me that these happen all the time.
Introduction to IBM Storwize V7000
I knew I was in trouble when the request for me to present Storwize sounded like something from [Mission Impossible]:
"Good morning, Mr. Pearson. Your mission, should you choose to accept it, involves presenting Storwize V7000 in Auckland, New Zealand. You may also present the Storwize V7000 Unified, but it is essential that you not cover the SAN Volume Controller or SONAS products from which they are based upon, as you will not have enough time. The audience is very technical, so be careful. As always, should any questions come up that you cannot answer, the conference coordinators will disavow all knowledge of your actions, nor reimburse your laundry charges. This message will self-destruct in five seconds."
Well, I accomplished my mission in 75 minutes. I was able to cover the block-only version of the IBM Storwize V7000, with support for clustering the control enclosures, expansion drawers and external storage virtualization. I then spent a few minutes on the block-and-file Storwize V7000 Unified, which adds support for CIFS, NFS, HTTPS, FTP and SCP protocols through two new "file modules", with integrated support for backup and anti-virus checking. I covered both IBM Easy Tier for sub-LUN automated tiering between Solid-State Drives (SSD) and spinning disk, as well as Active Cloud Engine for file-based movement between disk and tape.
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:
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!
This week I was aboard the Queen Mary in Long Beach, California! This was a business event organized by [Key Info Systems], a valued IBM Business Partner. Key Info resells IBM servers, storage and switches.
The Queen Mary retired in 1967, and has been converted into a hotel and events venue. The locals just parked their car and walked on board, but I got to stay Tuesday through Thursday in one of the cabins. It was long and narrow, with round windows! There were four dials for the bathtub: Cold Salt, Hot Fresh, Cold Fresh, and Hot Salt.
Stepping on the boat was like walking back in time through history! If you decide to go see it, check out the [Art Deco bar at the front of the Promenade deck. The ship is still in the water, but is permanently docked. It is sectioned off to prevent the ocean waves from affecting it, so we did not have the nauseous moving back and forth normally associated with cruise ships.
(It is with a bit of irony that we are on the Queen Mary just days after the tragedy of the [Costa Concordia], the largest Italian cruise ship that ran aground near Isola de Giglio. The captain will have to explain how he [fell into a lifeboat] before he had a chance to wait for everyone else to get safely off the shipwreck. He was certainly no [Captain Sulley]! I am thankful that most of the 4,200 people survived the incident.)
Lief Morin, Founder and Chief Executive for Key Info Systems, kicked off the meeting with highlights of 2011 successes. I have known Lief for years, as Key Info comes to the Tucson EBC on a frequent basis. This event was designed to give his sellers an update of what is the latest for each product line, and what to look forward to in the next 12-18 months.
The next speaker was from Vision Solutions that provides High Availability solutions for IBM i on Power Systems. In 2010, their company nearly doubled in size with the acquisition of Double-Take, which provides data replication for x86 servers running Windows, Linux, VMware, Hyper-V and other hypervisors. The capabilities of Double-Take sounded similar to what IBM offers with [Tivoli Storage Manager FastBack] and [Tivoli Storage Manager for Virtual Environments].
Dinner at Sir Winston's
Rather than take the "Ghosts and Legends" tour, I opted for dinner at the Queen Mary's signature restaurant, Sir Winston's. This is a fancy place, so dress accordingly. If you want the Raspberry soufflé, order it early as it takes 30 minutes to prepare!
[Storwize V7000], including the new Storwize V7000 Unified configuration
Storage is an important part of the Key Info Systems revenue stream, so I was glad to have lots of questions and interactions from the audience.
Murder Mystery Dinner
The acting troupe from [Dinner Detective] put on quite the show for us! With all that is going on in the world, it is good to laugh out loud every now and then.
In other murder mystery dinners I have participated in, each person is assigned a "character" and given a script of what to say and when to say it. This was different, we got to pick our own characters. I chose "Doctor Watson", from the Sherlock Holmes series. Several attendees thought it was a double meaning with [IBM Watson], the computer that figured out the clues on Jeopardy! television game show, and has since been [put to work at Wellpoint] to help out the Healthcare industry.
After the "murder" happened, two actors portraying policemen selected members of the audience to answer questions. We didn't get a script of what to say, so everyone had to "ad lib". I was singled out as a suspect, and had fun playing along in character. One of the attendees afterwards said he was impressed that I was able to fabricate such amusing and elaborate responses to their personal and embarassing questions. As a public speaker for IBM, I have had a lot of practice thinking quickly on my feet.
Fibre Channel and Ethernet Switches
The next two speakers gave us an update on Fibre Channel and Ethernet switches, and their thoughts on the inevitability of Fibre Channel over Ethernet (FCoE). One of the exciting new developments is the [Brocade Network Subscription] which creates a flexible pay-per-use Ethernet port rental model for customers. This is especially timely given the Financial Accounting Standards Board proposed [FASB Change 13] that affects operating leases in the balance sheet.
With the Brocade Network Subscription, you pay monthly for the ports you are using. Need more ports, Brocade will install the added gear. Use fewer ports, Brocade will take the equipment back. There is no term endpoint or residual value like tradtional leasing, so when you are done using the equipment, give it back any time. This is ideal for companies that may need to have a lot of Ethernet ports for the next 2-3 years, but then plan to taper down, and don't want to get stuck with a long-term commitment or capital depreciation.
The last speaker was from VMware. IBM is the #1 reseller of VMware, and VMware commands an impressive 81 percent marketshare in the x86 virtualization space. The speaker presented VMware's strategy going forward, which aligns well with IBM's own strategy, to help companies Cloud-enable their existing IT infrastructures, in preparation for eventual moves to Hybrid or Public cloud deployments.
Special thanks to Lief Morin for sponsoring this event, Raquel Hernandez from IBM for coordinating my travel, and Pete, Christina and Kendrell from Key Info Systems for organizing the activities!
Well, it's Tuesday again, and you know what that means! IBM Announcements! Typically, IBM System Storage has three to five major product launches per year. Making announcements every Tuesday would have been two frequent, and having one big announcement every two or three years would be too far apart. Worldwide combined revenues for storage hardware and software grew double digits last year, comparing full-year 2011 to the prior 2010 year, and I am sure that 2012 will also be a good year for IBM as well! This week we have announcements for both disk and tape, but since 2012 is the 60th Diamond Anniversary for tape, I will start with tape systems first.
TS1140 support for JA/JJ tape cartridges
The TS1140 enterprise tape drive was announced at the [Storage Innovation Executive Summit] last May. It supported a new E07 format on three different new tape cartridges. Models "JC" was 4.0TB standard re-writeable tapes, "JY" was 4.0TB WORM tapes, and "JK" were 500GB economy tapes that were less expensive, but offered faster random access.
Generally, IBM has adopted an N-2 read, N-1 write [backward compatibility]. This means that the TS1140 could read E05 and E06 formatted tapes on JB and JX media, and could write E06 format on JB and JX media. However, there are a lot of older JA and JJ media, especially as part of TS7740 environments, so IBM now supports TS1140 drives to read J1A formatted JA and JJ media. This is not just for TS7740 environments, any TS1140 in stand-alone or tape library configurations will support this as well.
TS7700 R2.1 enhancements
IBM is a leader in tape virtualization with or without physical tape as back-end media. There are two hardware models of the [IBM Virtualization Engine TS7700 family] for the IBM System z mainframe. These virtual libraries are referred to as "clusters" in IBM literature.
The TS7740 Virtual Tape Library supports putting virtual tape images on disk first, then move less-active data to physical tape, which I covered in my blog post [IBM Announcements - July 2007].
A unique feature of the TS7700 series is support for a Grid configuration, which allows up to six different TS7700 clusters to be grouped into a single instance image. These clusters can be in local or remote locations, connected via WAN or LAN connections.
R2.1 is the latest software release of this successful IBM's TS7700 series.
True Sync Mode Copy. Before R2.1, the TS7700 offered "immediate mode copy". An application would write to a virtual tape, and when it was done with the tape and performed an unmount, the TS7700 would then replicate the tape contents to a secondary cluster on the grid. With True Sync Mode, data contents are replicated per implicit or explicit SYNC points. This is another IBM first in the IT tape industry.
Remote Mount Fail-over. When you have two or more TS7700 clusters in a grid configuration, you can do remote mounts. We've added fail-over multi-pathing up to four paths, so that if a link to a remote cluster is down, it will try one of the others instead.
Parallel Copies and Pre-Migration. On of my 19 patents is for the pre-migration feature for the IBM 3494 Virtual Tape Server (VTS) that carries forward into the TS7700, and is also used in the SONAS and Information Archive products. However, when the grid architecture was introduced, the engineers decided not to allow pre-migration and copies to secondary clusters to occur concurrently. Now these two operations can be done in parallel.
Merge two grids into one grid. Now that we can support up to six clusters into a single grid, we have people with 2-cluster and 3-cluster grids looking to merge them into one. Of course, all the logical and physical volume serials (VOLSER) must be unique!
Accelerate off JA/JJ Media. There are a lot of older JA and JJ media still in TS7700 libraries. This feature allows customers to speed up the transition to newer physical tape media.
Copy Export to E06 format on JB media. This one is clever, and I have to say I would have never thought about it. Let's say you have a TS7740 with TS1140 drives, but you want to export some virtual tapes to physical media to be sent to someone who only has a TS7740 connected with older TS1130 drives. These older drives can't read new JC media nor make sense of the E07 format. This feature will let you export to older JB media in E06 format so that it will be fully readable at the new location on the TS1130 drives.
Copy Export Merge service offering. Thanks to mergers and acquisitions, it is sometimes necessary to split off a portion of data from a TS7700 grid. In the past, IBM supported sending this export to a completely empty TS7700 library, but this new service offerings allows the export to be merged into an existing TS7700 that already contains data.
LTFS-SDE support for Mac OS X 10.7 Lion
How do people still not yet know about the Linear Tape File System [LTFS]? I mentioned this in my blogs back in 2010 in [April], [September], and [November]. Last year, LTFS was the [NAB Show Pick Hits Award] and an [Emmy] for revolutionizing the use of digital tape in Television broadcasting.
In layman's terms, the Single Drive Edition [LTFS-SDE] allows a tape cartridge to be treated like USB memory stick. It is supported on the LTO5 tape drives for systems running various levels of Windows, Linux and Mac OS X. Prior to this announcement, IBM supported Snow Leopard (10.5.6) and Leopard (10.6), and now supports Mac OS X 10.7 "Lion" release.
IBM first introduced Solid-State Drives (SSD) back in 2007 where it made sense the most, in [drive-for-drive replacements on blade servers in the IBM BladeCenter]. Blade servers typically only have a single drive, and SSD are both faster and use less energy on a drive-for-drive comparison, so this provided immediate benefit. Today, SSD are available on a variety of System x and POWER system servers.
In 2008, IBM rocked the world by being the first to reach [1 Million IOPS with Project Quicksilver]. This was an all-SSD configuration which many considered unrealistic (at the time), but it showed the potential for solid state drives.
When the [XIV Gen3 was Announced - July 2011], each module included an 1.8-inch "SSD-Ready" slot in the back. IBM made a Statement of Direction that IBM would someday offer SSD drives to put in these slots. Today's announcement is that IBM has finalized the qualification process, so now XIV Gen3 clients can have 400GB of usable non-volatile SSD read cache added to each module. This SSD can be added to existing XIV Gen3 boxes in the field, or it can be factory-installed in new shipments. If you have a 15-module XIV, that's 6TB of additional read cache! This SSD is entirely managed by the XIV Gen3, so you won't have to spend weeks reading manuals or specifying configuration parameters.
When you carve volumes on the XIV, you now have an option to enable or disable use of the SSD cache for each volume. Since XIV is being used in private and public cloud deployments, this offers the ability to offer premium performance at premium prices. The use of SSD is complementary to IBM XIV Quality of Service (QoS) performance levels, which are determined by host instead.
Well, that's the first major IBM System Storage launch of 2012. Let me know what you think in the comment section below.
