IBM doesn't publicly report subset numbers on individual product lines, but we are growing, albeit single-digit growth, on the high-end with our IBM System Storage DS8000 and DS6000 series products. Single digit growth is not "booming", but it is what we expected in this space, so it is not like we are"feeling the chill" as Robin stated.Obviously, if the U.S. market overall is doing poorly, then it must be from something else. IBM's success appears to be from organic growth in our Asia and Europe markets, and taking marketshare away from the top two contenders, EMC and HDS. Here are my thoughts why:
EMC is remodeling its kitchen
Not happy with its status as #1 disk hardware specialty shop, EMC is admirably trying to redefine itself as an ["information infrastructure"] company, buying up software companies and introducing new storage services. [Byte and Switch] reports onEMC's recent acquisitions:
EMC is the latest vendor to pin its colors to the SaaS mast, revealing its plan to offer SaaS-based archiving services during its recent Innovation Day in Boston.
EMC gave another clear indication of its SaaS intentions last month, when it spent $76 million to acquire online backup specialist Mozy.
IBM has offered[Managed Storage Services] foryears through our Global Technology Services (GTS) division. Gartner recognized IBM as the #1 leader in storageservices, with three times more revenues than EMC in this space.
As with a restaurant that is remodeling its kitchen, it can expect a temporary drop inrevenue. If it is done right, customers will come back to a bigger brighter restaurant. If not, the restaurant re-opens as a much smaller lesser version of itself. Recent events this year might incent EMC to get that kitchen done quickly:
A recent [class-action lawsuit]might result in having EMC's "86 percent male" sales force goes to sexual harassment sensitivity training, takingtime away from selling high-end storage arrays in the field. Analysts consider "high-end" boxes as those costingover $300,000 US dollars. Because of the money involved, there is a lot of competition for high-end storage, so face-to-face time with prospective customers is crucial to making the sale.Anytime any vendor is mentioned in a lawsuit (andcertainly IBM has had its share in the past, as Chuck Hollis correctly points out in the comment below), priorities get shifted, and there is potential dip in revenues.
Dell acquires EMC's rival EqualLogic. Dell resold EMC midrange storage, like CLARiiON, so this should notimpact their high-end storage sales. While Dell will be allowed to sell EMC until 2011, this new acquisition mightmean Dell leads with the EqualLogic offerings, and that could potentially reduce EMC revenues in the midrange space.
IBM went through a similar phase in the 1990's, redefining itself from an "IT Technology" company, intoa "Systems, Software and Services" company. These transitions can't be done in a quarter, or even a year, theytake several years. IBM lost business to EMC in the 1990s, but is back with a stronger portfolio in the 2000's, and so IBM's kitchen remodeling effort appears to be paying off. We will see what happens with EMC in a few years.
HDS puts on the white lab coats
Meanwhile, HDS appears interested in taking over as #1 disk hardware specialty shop.For years, Hitachi was the stereotypical JCM (Japanese IBM-compatible manufacturer) that made well-engineered"me, too" storage arrays. They would see what innovators like IBM and EMC were doing, and copy them. Recently,however, they seemed to have changed strategy, introducing new featuresand functions on their high-end USP-V device, like[Dynamic Provisioning].
The problem is that customers don't want to feel like [Guinea pigs] in an experimental lab, especially withmission-critical data that they trust to their most-available, most-reliable high-end disk storage systems.Like IBM and EMC and the rest of the major storage vendors, Hitachi has top-notch engineers making quality products, but new features scare people, and so there is a lag in the adoption of new technologies.
In our youth, we might have preferred beer with recent born-on dates, and tequila aged less than 90 days. But as weget older, we switch to drinks like wine and whiskey, aged years, not weeks. The same is true for themarketplace. New start-ups and other "early adopters"might be willing to try fresh new features and functions on their storage systems, but more established enterprises prefer storage with more mature and stable microcode.Storage admins want to leave at the end of the day, knowing that the data will still be there the next morning. In tough financial times, many established companies want the technological equivalent to ["comfort food"], nothing spicy or exotic, but simplehearty fare that fills the belly and keeps you satisfied.
Recognizing this, IBM often introduces new features and functions on its midrange lines first, and position them accordingly. Once customers are comfortable with the concepts, IBM then can consider moving them into the high-end lines. For example, dynamic volume expansion was introduced on the DS4000 and SAN Volume Controller first, and once proven safe and effective, brought over to the DS8000 series. This strategy has served us well.
Well those are my theories. If you have a different explanation of why storage vendors are not doing well in thehigh-end, drop me a comment!
[R&D Magazine] recently conducted a survey that prompted readers to identify the world's most successful Research and Development (R&D) companies. The results are in: IBM was recognized as the best R&D company in the world when several different categories were evaluated, including:
R&D spending as a percentage of revenue
the number of patents
new products in development
The survey considered additional information on more than 130 companies such as data on intellectual property, community service and financial growth trends. Readers were also asked five distinct questions, including the following:
Where would you like to work based on their R&D?
What companies have the most improved R&D in the past five years?
What companies are the leaders in R&D?
Which company's R&D has the strongest influence on society?
Which company's R&D is the most proactive in high tech challenges?
Since it is often 5-15 years between when a scientist in one of our many research labs comes up with a clever idea, to when it is a market success, it is good to have external recognition for the R&D efforts we are doing right now.Here is a link to a [four-page PDF] of the magazine article.
Take for example IBM's recent breakthrough in Silicon photonics. Supercomputers that consist of thousands of individual processing nodes, typically running Linux on dual-core or quad-core processors, connected by miles of copper wires could one day fit into a laptop PC. And while today’s supercomputers can use the equivalent energy required to power hundreds of homes, these future tiny supercomputers-on-a-chip would expend the energy of a light bulb, so this solution is more "green" for the environment.According to the [IBM Press Release]:
The breakthrough -- known in the industry as a silicon Mach-Zehnder electro-optic modulator -- performs the function of converting electrical signals into pulses of light. The IBM modulator is 100 to 1,000 times smaller in size compared to previously demonstrated modulators of its kind, paving the way for many such devices and eventually complete optical routing networks to be integrated onto a single chip. This could significantly reduce cost, energy and heat while increasing communications bandwidth between the cores more than a hundred times over wired chips.
“Work is underway within IBM and in the industry to pack many more computing cores on a single chip, but today’s on-chip communications technology would overheat and be far too slow to handle that increase in workload,” said Dr. T.C. Chen, vice president, Science and Technology, IBM Research. “What we have done is a significant step toward building a vastly smaller and more power-efficient way to connect those cores, in a way that nobody has done before.”
Today, one of the most advanced chips in the world -- IBM’s Cell processor which powers the Sony Playstation 3 -- contains nine cores on a single chip. The new technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them. Using light instead of wires to send information between the cores can be 100 times faster and use 10 times less power than wires.
But ITSM is more than just a better way to manage operational tasks, it is focused on the best practices of the IT Infrastructure Library (ITIL) which has been adopted bythe European Union, and now being adopted worldwide by both government agencies and private enterprises as a smartway to run your IT environment.
Of course, we've designed our solutions to apply to your entire IT environment, supporting both IBM and non-IBM equipment, so even if not all of your servers and storage come from IBM, at least your software can be.[Read More]
This week I am in Minneapolis, MN, so was hoping that the complicated process of moving this blog over to "MyDeveloperWorks" would happen while I was gone, but alas, that does not appear to be the case.
Meanwhile, my partner in crime, Barry Whyte, has moved his blog [Storage Virtualization]successfully over to the new server.
Perhaps next week. If all goes well, the URL links should redirect correctly, but those of you out there using feed readers might require you to re-subscribe to get the right RSS feeds.
"... firms don't have the detailed electricity consumption data they need to implement energy efficiency initiatives. What they have is an energy bill for a facility."
A common adage is that "you can't manage what you don't measure." IBM has beefed up the ability to measure andmonitor electricity usage, not just IBM servers and storage, but also non-IBM IT equipment and facilities infrastructurelike UPS, HVAC, lighting and security alarm systems.
Hitch Green IT to data centre refurbishment projects
"Energy savings alone don't constitute a business case to overhaul an existing data centre, undertake a refurbishment project or build a new Green Data Centre."
Either CIOs don't have the measurements of electricity to perform an ROI or cost/benefit analysis, or the facilitiesfolks that sense improvements are possible may not see the big picture compared to other business investments.Instead, IBM seeks to incorporate IT energy efficiency best practices into existing business plans for data center improvements.
Tackle corporate energy efficiency and emissions
"... a strategy discussion and corporate carbon diagnostic are the start point to stimulate demand. Not a cold sell on Green IT."
Project Big Green is more than just an IT project.IBM's Global Business Services consultants have transformed it into a Carbon Management Strategy encompassing employees, information, property, the supply chain, customers and products. For companies that are looking atreducing their carbon footprint overall, this approach makes a lot of sense.
Differentiate offerings by industry and country
"The inability to get more power into urban data centres has driven demand for energy efficiency by banks, telcos and outsourcers."
Different countries, and different industries, have different priorities.Europe, and in particular the UK, focuses on carbon emissions as much as energy costs due to mandatory emissions caps.For data centers in the largest cities, an increase in electrical supply may not be available, or be too expensive,and the time it takes to build a new data center elsewhere, typically 12-18 months, may not be soon enough to handlecurrent business growth rates. Energy efficiency projects can help buy them some time.
Plan for slow customer adoption
"IBM is developing the market for IT energy efficiency and carbon management services. And its very much an early stage market today."
IBM is frequently on the forefront of new technologies and emerging markets, so it is no surprise that we areused to dealing with slow customer adoption. The combination of high energy costs, tightening regulations and stakeholder pressure will drive the market. Larger companies and government organizations that have the meansto make these necessary changes will probably lead the adoption curve.
Prepare for investment barriers to IT energy efficiency
"With the low hanging fruit picked, IBM has found that there is an unwillingness to spend money on planting a new orchard."
IBM has helped IT clients with quick fixes offering rapid payback such as adjusting data center temperature and humidity to reduce energy consumption. But in the current economic environment, persuading firms to install variable speed fans with a 6-year payback is much tougher. Again, this is a matter of CIOs and other upper level management balancingfinancial investment decisions with some foresight and vision for the future.
Project Big Green launched back in May 2007, and last month IBM renewed its commitment with Project Big Green 2.0,continuing to enhance product and service offerings in support for this much needed area. And while the leadersin the G8 Summit will discuss a variety of topics, three top "green" issues on their agenda include rising energy costs, global climate change and controlling carbon emissions.
Tuesday is always good for announcements. Today, Gartner, Inc. announced that IBM has taken over HP in its climb to the top. I'll quote directly from today's press release:
STAMFORD, Conn., March 6, 2007 — Worldwide external controller-based (ECB) disk storage revenue totaled $15.2 billion in 2006, a 4.1 percent increase over 2005 revenue of $14.6 billion, according to Gartner, Inc.IBM overtook Hewlett-Packard for the No. 2 position in 2006 (see Table 1). IBM’s worldwide ECB market share increased to 15.8 percent, while HP’s market share dropped to 13.1 percent.
IBM beat HP both in 4Q06, as well as 2006 full year.You can read more about it from Gartner Dataquest report “Market Share: Disk Array Storage, All Regions, All Countries, 1Q05-4Q06" on their website. (Note: non-IBMers might need an account with Gartner to access this, not sure)
The focus was on external controller-based disk, not external controller-less SCSI/SAS disk, not disk arrays posing as virtual tape libraries, nor any disk sold inside HP, Sun, IBM or Dell servers. This is to compare with disk-only vendors such as EMC and HDS. The revenues reflect hardware only, including hardware-related parts of financial leases and managed services. Revenues from optional priced software features such as multi-pathing drivers, management software, or advanced copy services were excluded.I discussed these types of analyst reports back in blog post last September: Space Race Heats Up.
These marketshare numbers are based on revenues, not units or terabytes. When a box gets sold, the revenue was counted toward the vendor that sold it, not the manufacturer that built it. In this last report:
When Dell sells an EMC box, it gets counted as Dell. When Fujitsu Siemens sells an EMC box, it gets counted as "Other".
When HP sells an HDS box, it gets counted as HP. When Sun sells the HDS box, it gets counted as Sun.
When IBM sells its System Storage N series (from the OEM agreement with NetApp), it gets counted as IBM. Both IBM and NetApp experienced growth in the NAS/unified storage arena.
It's still cold here in the Washington DC area, but at least good news like this helps warm me up!
A Forrester Analyst drew the analogy of a river to the upcoming onslaught of millennials. Some 100 years ago, smart companies positioned themselves near rivers, the water provided power as well as a means of transporting products. However, today, being positioned near a river doesn't ensure company success, and there are plenty of examples of companies that have existed a long time now filing for bankruptcy.
As we get out of this recession, the war for people will be intense. In the United States, as many as 76 million[Baby Boomers], born between 1946 and 1964, are retiring or approaching retirement, being replaced by 46 million [Gen X], born between 1965 and 1976. By 2010, there will be as many as 31 million [Millenials], born between 1977 and 1998, in the workforce.
To drive the point home, the Forrester analyst cited [Whirlpool] as an example, a company more than 100 years old, with 73,000 employees across 170 countries. Whirlpool manufactures kitchen, laundry and other home appliances. From 1997 to 2002, however, Whirlpool's per-ticket sales were dropping at a rate of 3.4 percent per year. To reverse this trend, they established the Whirlpool Young Professional program, assigned I-mentors, and invested in Web 2.0 collaboration tools. They realized that they needed to harness the Gen X and Millenial energy. The result?From 2002 to 2006, they had a compete turn-around, with per-ticket sales growing 5.9 percent per year.
Since I covered IBM's keynote session yesterday, I thought it would only be fair to cover HP's today.IBM and HP are the top two IT vendors in the world, and not surprisingly also the top two IT storage vendors, and are both platinum sponsors for this event.
Phil McKinney, VP and CTO of Hewlett-Packard (HP) Personal Systems Group
Phil presented "Enabling Innovation: A Strength In Any Economy", which covered HP's approach to innovationnot just within HP itself, but also to help their customers. He presented an interesting progression forIT. In the first, IT is very technology-centric, focusing on standardizing platforms and automating tasks.In the second, IT is more process-oriented, standardizing and automating business processes measured for reliable IT outcomes. In the third, IT is business-aligned, standardizing and automating services, measured on business results. He argued that the challenge was for companies to transform their IT through this progression to improve business impact.
To help customers, HP focuses on four aspects of an Innovation Management Framework:
Strategy, Measurement and Metrics
Systems, Collaboration tools and knowledge management
Culture, Education and Training
Ecosystem, business partnerships and customer innovation
He wrapped up his talk reminding us that ideas without execution are just hobbies.
Tom Peck, Senior VP and CIO, Levi Strauss & Co
Levi Strauss & Co. manufactures denim pants and other clothing apparel, and has been doing so for more than 150 years. Tom made a point to actually wear denim jeans and a sports coat on stage for his talk.His presentation "Dealing with Disruption" was not about disruptive technologies, but rather the disruption the economic downturn has impact the retail industry. To survive through this recession, IT leaders needto be bold about their hiring, reorganizing and rethinking of IT because disruption is everywhere.
IT is not a cost center at Levi Strauss, and represents only 3.5 percent of their total expenses. Instead, they have educated their stakeholders that IT is an investment for competitive advantage. They have focused on simplifying, which is important because their line of pants has grown incredibly complex. When you factor in the different fabrics, colors, styles, sizes, fit and finish, you end up with a large numberof different pants. This complexity came from an effort to provide exactly what every customer thought they needed. He cited a great quote:
“If I had asked people what they wanted, they would have said faster horses.” --- Henry Ford
This same complexity occurs in IT. To address the changes needed, Tom combined "Lean IT" principles with "Six Sigma" methodologies. Lean IT helped identify problems with the overall flow of processes and provided the tools to remove steps that did not add value. Six Sigma was applied to the remaining steps that did add value, to improve capability and effectiveness.
Companies that have been around for awhile, like IBM, Whirlpool and Levi Strauss & Co., have learned to adapt to the changing business and IT landscape, and adopt new ideas for new ways of doing things.
Continuing my blog coverage of the [Forrester IT Forum 2009 conference],I finally catch up with some keynote sessions this morning. Here's my recap on the rest of the main tent general session keynote presentations from BP, Microsoft and CFIL.
Dana Deasy, CIO and Group VP, Information Technology and Services (IT&S), BP
Dana presented "The gift we’ve been given – reinventing the IT organization". He is the CIO of BP, an energy company that made over 360 billion dollars selling oil and gas. In fact, it is the fourth largest company in the world, with 92,000 employees in more than 100 countries. Back in 2007, business was good but the senior management team felt that IT needed to be straightened out.Dana was brought in as a "fresh thinking" outsider, managing a group 4000 IT staff composed mostly of contractors, dealing with more than 2000 IT suppliers and more than 60 versions of SAP.
Dana presented the results of their IT makeover. In the first year, he was able to cut out 400 million US dollars from the IT budget, including the reduction of 500 people from the IT staff. He increased the employee/contractor ratio to 40/60, with plans to bring this up to 65/35 over the next year. He was able to get 1800 IT employees to perform a self-assessment to understand their strengths and weaknesses. He was able to centralize the IT leadership team, and deploy a common [ITIL] best practices implementation.
What did he learn from all this? Here were his top four "lessons learned":
No time to dwell but know your facts
Work in parallel to push the pace of change
Listen but in the end take your own counsel
Tell a compelling story to energize your employees and your leadership
Chris Capossela, Senior VP of Information Worker Product Management Group, Microsoft
Chris presented "Uncovering Value in the Cloud and On Your Desktop", onhow Microsoft customers are taking advantage of the software they have already purchased.For example, Jamba Juice was able to use Microsoft SharePoint to cut down locating documents from 15 minutes to just seconds, reducing 10-15 hours per week for more than 500 managers. More importantly, they were more confident that document they found was the right one. This is often referred to as "one version of the truth." In another example, Tyson Foods was able to connect Microsoft Word to their SAP application, and have that then connect to their Microsoft SharePoint.
Chris was amazed that many Microsoft customers don't take advantage of all that is available to them.He gave four examples:
Planning Services: If you buy an enterprise license to Microsoft products, you get planning services, from either Microsoft's own Microsoft Consulting Services or from thousands of Microsoft Business Partners. Only 8 percent of customers take advantage of this.
Home Use Rights: For enterprise license customers, employees can purchase "home use rights" to use the Enterprise level of Microsoft Office software for only 10 US dollars, but only about 3 percent take advantage of this.
Training: Many enterprise licenses come with 2-4 weeks of training vouchers, but only 40 percent take advantage of these vouchers.
E-Learning: Microsoft also offers e-learning, which Microsoft customers can either have delivered from Microsoft's own hosted services, or they can get a copy of the E-learning materials hosted inside their own company firewall. Again, few take advantage of this.
Chris wrapped up his presentation by citing some examples of customers that migrated from in-house, on-premises collaboration software to Microsoft's "Exchange Online" and "SharePoint Online" cloud computing Software-as-a-Service [SaaS] offerings. The cloud versions of these software do not offer all the features as the on-premise versions, but Microsoft is working to close this gap.
(IBM offers similar cloud computing services for email and collaboration called [LotusLive])
Gary presented "Tough Times: Opportunity for Innovation and Corporate Makeover". He had some greatquotes intended to help people become better leaders, like this:
“Leadership failures do not usuallyresult from leaders not knowing what todo; rather these failures result becauseleaders fail to do what they know fullwell they should and must do.Most leaders never get fully comfortable withthe changes that they wish for theirorganizations.”
Change the Conversation - employees want to have a compelling reason to change.
Create a compelling description of the future - employees want a vision of where they are headed.
Emotionally enlist employees in the cause - leaders are not remembered for their attributes, as much as the causes they stood for.
Help me understand the business - employees often do not have information in context to act accordingly.
Choose passionate - employees want to see leaders that are passionate and confident on the process and strategic direction.
Create a To-Stop list - we all have "to do" lists, but perhaps you need a "to don't" list. In other words, a list of bad habits and practices you need to discontinue.
Gary indicated that trust must be given before it is earned. If a leader doesn't trust the employees, how do you expect the employees to trust the leader? When asking employees to change their behavior, or self-assess their own skills, a leader must emphasize "I mean you no harm." Otherwise,mistrust will undermine the intended results.
The keynote sessions the past three days have provided clear motivation to the CIOs and IT leaders in the audience to consider making the necessary changes, with impressive results and actionable advice.
This week, I presented at the "IBM TechU Comes to You" event in beautiful Dubai, United Arab Emirates. This was a three-day event, so here is my recap of Day 3.
IBM Spectrum Control Family - The right products for your storage management needs
Mike Griese (IBM Spectrum Storage Evangelist) presented the IBM Spectrum Control family. There are now four editions of IBM Spectrum Control:
IBM Spectrum Control Based Edition -- comes included with specific IBM Storage products to provide Cloud APIs such as those required for VMware.
IBM Spectrum Control Standard Edition -- Includes "Based Edition" and adds monitoring, provisioning and troubleshooting for IBM and non-IBM storage devices. Also includes IBM Copy Services Manager for select IBM storage devices.
IBM Spectrum Control Advanced Edition --Includes "Standard Edition" and adds Spectrum Protect Snapshot to take application-aware snapshots, and the Storage Analytics Engine to optimize data placement.
IBM Spectrum Control Storage Insights -- A "Software-as-a-Service" subset of "Advanced Edition" for IBM storage products.
Implementation of Incremental Forever Backup and Deduplication with Spectrum Protect
This was combination of an overview of IBM Spectrum Protect plus an update of the latest v7.1.5 release. For those who use alternative backup software like Veritas NetBackup or Commvault Simpana, I explained how to implement "Incremental Forever" backup, which has been shown repeatedly by analysts and studies as being far more efficient than traditional backup methods like Full+Incremental or Full+Differential.
For those who may be using an earlier version of IBM Tivoli Storage Manager, I presented the new "Dedupe 2.0" features, including the new concept of "Container Pools" that can either be "Directory Pools" on SAN or NAS-based disk storage, or "Cloud Pools" on object storage, like IBM Cleversafe or IBM SoftLayer.
Spectrum Control Storage Insights - Redefining storage management simplicity
Mike Griese presented the newest member of the IBM Spectrum Control. Storage Insights is a Software-as-a-Service offering, that was recently reduced in price: only $250 per month for the first 50TB. Increasing amounts of storage capacity monitored are tiered at lower and lower prices.
Real-time Compression in Database environment
When it comes to compression, should you compress at the database level, or in the storage device? Database management systems like IBM DB2 and Oracle DB offer row-level or page-level compression.
IBM Real-time Compression available in IBM XIV and all of the latest Spectrum Virtualize products: SAN Volume Controller, Storwize V7000, Storwize V7000 Unified, Storwize V5000, FlashSystem V9000, as well as any of these in the VersaStack converged system from IBM and Cisco.
IBM ran tests that compared volume with database uncompressed, database-based compression, compression on IBM Storwize V7000 with IBM Real-time Compression, and a test run that does both database and storage-based compression together. The results might surprise you!
I explained the pros and cons of each method of compression, and why you might choose one or the other.
Be Ready for Object Storage with CleverSafe
Eric Forestier (IBM Montpelier) presented a quick overview of IBM Cleversafe, then did a live demo of the PUT and GET features. For example, he used the Linux CURL command to upload a video file as an object in his IBM Cleversafe cluster back in France. Then he used a regular browser to stream the video back.
Was Dubai too far away for you to attend? Want to hear the latest technical information about IBM Storage, but not willing to wait until the big [IBM Edge Conference] this September? We will have several more "IBM TechU Comes to You" events in May and June.
Well, I'm back from my vacation from Bali and Singapore, and am glad to seethat my fellow blogger BarryB [aka Storage Anarchist] also had a chance to take a break to exotic locations.
Next Thursday, in the USA, is [Thanksgiving holiday], so this will give me a chance to catch up on my email and read everyone's blog posts and product announcements.
The following week, December 2-5, I'll be attending the 27th annual [Data Center Conference] at the MGM Grand hotel and casino in Las Vegas, Nevada. IBM is a Premier and Platinum sponsor for this event.Look for me in one of the many break-out sessions, one-on-oneexecutive meetings, or IBM's "booth 20" at the solution center. Our team will be showingoff IBM's XIV, SVC and TotalStorage Productivity Center offerings, aswell as explaining IBM Information Infrastructure and the rest of theNew Enterprise Data Center strategy.
I'm glad this is the final day of the IBM Systems Technical Conference (STC08) here in Los Angeles.While I enjoyed the conference, one quickly reaches saturation point with all the information presented.
XIV Architecture Overview
Before this conference, many of the attendees didn't understandIBM's strategy, didn't understand Web 2.0 and Digital archive workloads,and didn't understand why IBM acquired XIV to offer "yet another disk systemthat servers LUNs to distributed server platforms." Brian Shermanchanged all that!
Brian Sherman, IBM Advanced Technical Support (ATS), is part of the exclusive dedicated XIVtechnical team to install these boxes at client locations, so he is very knowledgeable with the technical aspects of the architecture. He presented what the current XIV-branded model that clients can purchase now in select countries, and what the IBM-branded model will change when available worldwide.
Those who missed my earlier series on XIV can find them here:
Beyond this, Brian gave additional information on how thin provisioning, storage pools, disk mirroring, consistency groups, management consoles, and microcode updates are implemented.
N series and VMware Deep Dive
Norm Bogard, IBM Advanced Technical Support, presented why the IBM N series makes such great disk storage for VMware
deployments. This wasclearly labeled as a "deep dive", so anyone who got lost in all of theacronyms could not blame Norm for misrepresentation.
IBM has been doing server virtualization for over 40 years, so it makes sense thatit happens to be the number one reseller of VMware offerings.VMware ESX server is a hypervisor that runs on x86 host, and provides an emulationlayer for "guest Operating Systems". Each guest can hvae one or more virtualdisks, which are represented by VMware as VMDK files. VMware ESX server acceptsread/write requests from the guests, and forwards them on to physical storage.Many of VMware's most exciting features requires storage to be external to thehost machine. [VMotion]allows guests to move from one host to another, [Distributed Resource Scheduler (DRS)]allows a set of hosts to load-balance the guestsacross the hosts, and [High Availability (HA)] allows the guests on a failed hostto be resurrected on a surviving host. All of these require external disk storage.
ESX server allows up to 256 LUNs, attached via FCP and/or iSCSI, and up to 32 NFS mount points. Across LUNs, ESX server uses VMFS file system, which is a clusteredfile system like IBM GPFS that allows multiple hosts to access the same LUNs.ESX server has its own built-in native multipathing driver, and even provides FCP-iSCSIand iSCSI multipathing. In other words, you can have a LUN on an IBM System Storage N series thatis attached over both FCP and iSCSI, so if the SAN switch or HBA fails, ESX servercan failover to the iSCSI connection.
ESX server can use NFS protocol to access the VMDK files instead. While the default is only 8 NFS mount points, you can increase this to 32 mount points. NAS can takeadvantage of Link Aggregate Control Protocol [LACP] groups, what some call "trunking" or "EtherChannel". This is the ability to consolidate multiple streams onto fewer inter-switch Ethernet links, similar to what happens on SAN switches.For the IBM N series, IBM recommends a "fixed" path policy, rather than "most recently used".
IBM recommends disabling SnapShot schedules, and setting the Snap reserve to 0 percent.Why? A snapshot of an ESX server datastore has the VMDK files of many guests, all of which would have had to quiesce or stop to make the data "crash consistent" for theSnapshot of the datastore to even make any sense. So, if you want to take Snapshots, itshould be something you coordinate with the ESX server and its guest OS images, and notscheduled by the N series itself.
If you are running NFS protocol to N series, you can turn off the "accesstime" updates. In normal file systems, when you read a file, it updates the"access time" in the file directory. This can be useful if you are looking forfiles that haven't been read in a while, such as software that migrates infrequentlyaccessed files to tape. Assuming you are not doing that on your N series, you might as well turnoff this feature, and reduce the unnecessary write activity to the IBM N series box.
ESX server can also support "thin provisioning" on the IBM N series. There isa checkbox for "space reserved". Checked means "thick provisioning" and uncheckedmeans "thin provisioning". If you decide to use "thin provisioning" with VMware,you should consider setting AutoSize to automatically increase your datastorewhen needed, and to auto-delete-snap your oldest snapshots first.
The key advantage of using NFS rather than FCP or iSCSI is that it eliminates theuse of the VMFS file system. IBM N series has the WAFL file system instead, andso you don't have to worry about VMFS partition alignment issue. Most VMDK aremisaligned, so the performance is sub-optimal. If you can align each VMDK to a32KB or 64KB boundary (depending on guest OS), then you can get better performance.WAFL does this for you automatically, but VMFS does not. For Windows guests, use "Windows PE" to configurecorrectly-aligned disks. For UNIX or Linux guests, use "fdisk" utility.
What Industry Analysts are saying about IBM
Vic Peltz gave a presentation highlighting the accolades from securities analysts, IT analysts, and newsagencies about IBM and IBM storage products. For example, analysts like that IBM offersmany of the exciting new technologies their clients are demanding, like "thin provisioning", RAID-6 double-drive protection,SATA and Solid State Disk (SSD) drive technology.Analysts also like that IBM is open to non-IBM heterogeneous environments. Whereas EMC Celerra gateways supportonly EMC disk, IBM N series gateways and IBM SAN Volume Controller support a mix of IBM and non-IBM equipment.
Analysts also like IBM's "datacenter-wide" approach to issues like security and "Green IT". Rather than focusingon these issues with individual point solutions, IBM attacks these challenges with a complete"end-to-end" solution approach. A typical 25,000 square foot data center consumes $2.6 million dollars USD in power andcooling today, and IBM has proven technologies to reduce this cost in half. IBM's DS8000 on average consume26.5 to 27.8 percent less electricity than a comparable EMC DMX-4 disk system. IBM's tape systemsconsume less energy than comparable Sun or HP models.
IBM iDataPlex product technical presentation
Vallard Benincosa, IBM Technical Sales Specialist, presented the recently-announced [IBM System x iDataPlex].This is designed for our clients that have thousands of x86 servers, that buy servers "racks at a time", tosupport Web 2.0 and digital archive workloads. The iDataPlex is designed for efficient power and cooling,rapid scalability, and usable server density.
iDataPlex is such a radical design departure, that it might be difficult to describe in words.Most racks take up two floor tiles, each tile is 2 foot by 2 foot square. In that space, a traditionalrack would have servers that were 19 inches wide slide in horizontally, with flashing lights and hot-swappabledisks in the front, and all the power supply, fans and networking connections in the back. Even with IBM BladeCenter,you have chassis in these racks, and then servers slide in vertically in the front, and all of the power supply, fanand networking connections in the back. To access these racks, you have to be able to open the door on boththe front and back. And the cooling has to go through at least 26.5 inches from the front of the equipment to the back.
iDataPlex turns the rack sideways. Instead of two feet wide, and four feet deep, it is four feet wide, and two feet deep.This gives you two 19 inch columns to slide equipment into, and the air only has to travel 15 inches from frontto back. Less distance makes cooling more efficient.
Next, iDataPlex makes only thing in the back the power cord, controlled by an intelligent power distribution unit (iPDU) so you can turnthe power off without having to physically pull the plug. Everything else is serviced from the front door.This means that the back door can now be an optional "Rear Door Heat Exchanger" [RDHX] that is filled with running water to makecooling the rack extremely efficient. Water from a cooler distirubtion unit (CDU) can power about threeto four RDHX doors.
Let's say you wanted to compare traditional racks with iDataPlex for 84 servers. You can put 42 "1U" serversin two racks each, each rack requires 10 kVA (kilo-volt-amps) so you give it two 8.6 kVA feeds each, that is fourfeeds, and at $1500-2000 dollars USD per month, will cost you $6000-8000. The iDataPlex you can fit 84 serversin one 20 kVA rack, with only three 8.6 kVA feeds, saving you $1500-2000 dollars USD per month.
Fans are also improved. Fan efficiency is based on their diameter, so small fans in 1U servers aren't as effective as iDataPlex's 2U fans, saving about 12-49W per server. Whereas typical 1U server racks spend 10-20percent of their energy on the fans, the iDataPlex spends only about 1 percent, saving 8 to 36 kWH per year per rack.
Each 2U chassis snaps into a single power supply and a bank of 2U fans. A "Y"power cord allows you to have one cord for two power supplies. A chassis can hold either two small server "flexnodes"or one big "flexnode". An iDataPlex rack can hold up to 84 small servers or 42 big servers. Since each "Y" cord can power up to four "flexnode" servers, you greatly reduce the number of PDU sockets taken,leaving some sockets available for traditional 1U switches.
The small "flexnode" server can have one 3.5 inch HDD, or two 2.5 inch HDD, either SAS or SATA, and the big "flexnode" can have twice these.If you need more storage, there is a 2U chassis that holds five 3.5 inch HDD or eight 2.5 inch HDD. These areall "simple-swappable" (servers must be powered down to pull out the drives). For hot-swappable drives, a 3Uchassis with twelve 3.5 inch SAS or SATA drives.
The small "flexnode" server has one [PCI Express] slot, the big servers have two. Thesecould be used for [Myrinet] clustering. With only 25W power,the PCI Express slots cannot support graphics cards.
The iDataPlex is managed using the "Extreme Cluster Administration Toolkit" [XCAT]. This is an open source project under Eclipse that IBM contributes to.
Finally was the concept of "pitch". This is the distance from the center of one "cold aisle" to the next "cold aisle".On typical data centers, a pitch is 9 to 11 tiles. With the iDataPlex it is only three tiles when using the RDHX doors, or six tiles without. Most data centers run out of power and cooling before they run out of floor space, so having more dense equipmentdoesn't help if it doesn't also use less electricity.Since the iDataPlex uses 40 percent less power and cooling, you can pack more racks persquare foot of an existing data center floor with the existing power and cooling available. That is what IBM calls "usable density"!
What Did You Say? Effective Questioning and Listening Techniques
Maria L. Anderson, IBM Human Resources Learning, gave this "professional development" talk. I deal with different clients every week, so I fully understand that there is a mix of art and science incrafting the right questions and listening to the responses.The focus was on howto ask better questions and improve the understanding and communication during consultative engagements. Thisinvolves the appropriate mix of closed and open-ended questions, exchanging or prefacing as needed. This wasa good overview of the ERIC technique (Explore, Refine, Influence, and Confirm).
Well, that wraps up my week here in Los Angeles.Special thanks to my two colleagues, Jack Arnold and Glenn Hechler, both from the Tucson Executive Briefing Center,who helped me prepare and review my presentations!
The author is wondering whether EMC will try to avoid the fate of Hitachi's mainframebusiness, focusing on "moving into the IBM field" of offering software and services for more complete solutions.
Interestingly, one comment opines that EMC's acquisition of Documentum was "followed" byIBM's acquisition of FileNet, not realizing that IBM already has the leading documentmanagement software (IBM Content Manager).
Another comment cites IBM's recent push of Xen asanother example "following" EMC's acquisition of VMware, again not realizing that IBM has hadLogical Partition (LPAR) capability in its System z, System p and System i server lines formany years.
I did not register soon enough to get into the MGM Grand itself, so I am staying at a Hiltonat the other end of the Las Vegas strip, but am able to hop on the "Monorail" to get to the MGM,just in time for the breakfast and first welcome session.
This conference has a familiar set up: six keynote sessions, 62 break-out sessions, and fourtown hall meetings. Thanks to electronic survey devices on the seats, speakers were able to gatherreal-time demographics. A large portion of attendees, including myself, are attending this conference for theirfirst time. Here's my recap of the first three keynote sessions:
The Future of Infrastructure and Operations: The Engine of Cloud Computing
How much do companies spend just to keep current? As much as 70 percent! The speaker noted thatthe best companies can get this down to 10 to 30 percent, leaving the rest of the IT budget to facilitate transformation. He predicts that companies are transforming their data centers fromsprawled servers to virtualization, towards a fully automated, service-oriented, real-time infrastructure.
Whereas the original motivation for IT virtualization was to reduce costs, companies now recognizethat they greatly improve agility, the ability to rapidly provision resources for new workloads, and that this will then lead to opportunites for alternative sourcing, such as cloud computing.
The operating system is becoming commoditized, focusing attention instead to a new concept: the"Meta OS". VMware's Virtual Data Center and Microsoft's Azure Fabric Controller are just two examples.Currently, analysts estimate only about 12 percent of x86 workloads are running virtualized, but thatthis could be over 50 percent by 2012.In this same time frame, year 2012, storage Terabytes is expected to increase 6.5x fold, and WAN bandwidthgrowing 35 percent per year.
Virtualization is not just for business applications. There are opportunities to eliminate the mostcostly part of any business: the Personal Computer, poster child of the skyrocketing costs of the client/server movement. Remote hosting of applications, streaming of applications,software as a service (SaaS) and virtual machines for the desktop can greatly reduce costs of customizedPC images and help desk support.
Cloud computing not only reduces per costs per use, but provides a lower barrier of entry and somemuch needed elasticity.Draw a line anywhere along the application-to-hardware software/hardware stack, and you can define acloud computing platform/service. About 65 percent of the attendees surveyed indicated that they were already doing something with CloudComputing, or were planning to in the next four years.
To help get there, the speaker felt that Value-added Resellers (VAR) and System Integrators (SI) wouldevolve into "service brokers", providing Small and Medium sized Businesses (SMB) "one throat to choke" in mixedmultisourced operations. The term "multisource" caught me a bit off-guard, referring to having someworkloads run internally (insourced) while other workloads run out on the Cloud (outsourced). Largerenterprises might have a "Dynamic Sourcing Team", a set of key employees serving as decision makers, employing both business and IT skills to determine the best sourcing for each application workload.
What are the biggest obstacles to getting there? The speaker felt it was the IT staff. People and cultureare the most difficult to change. The second are lack of appropriate metrics. Here were the survey resultsof the attendees:
41 percent had metrics for infrastructure economic attributes
49 percent had metrics for qualities of service (QoS)
12 percent had metrics to measure agility, speed of resource provisioning
The Data Center Scenario: Planning for the Future
This second keynote had two analyst "co-presenters". The focus was on the importance of having a documented Data Center strategy and architecture. Unfortunately, most Data Centers "happen on their own", with a majoroverhaul every 5 to 10 years. The speakers presented some "best practices" for driving this effort.
The first issue was to identify tiers of criticality, similar to those by the[Uptime Institute]. In their example, the most criticalworkloads would have perhaps recovery point objectives (RPO) of zero, and recover time objectives of lessthan 15 minutes. This is achievable using synchronous mirroring with fully automation to handle the failover.
The second issue was to recognize that many applications were designed for local area networks (LAN), butmany companies have distributed processing over a wide area network (WAN). Latency over these longer distancescan kill distributed performance of these applications.
The third issue was that different countries offer different levels of security, privacy and law enforcement.Canada and Ireland, for example, had the lowest risk, countries like India had medium risk, and countries likeChina and Russia had the highest risk, based on these factors.
The speakers suggested the following best practices:
Get a better understanding of the costs involved in providing IT services
Centralize applications that are not affected by latency, but regionalize those that are affected toremote locations to minimize distance delays.
Work towards a "lights out" data center facility, with operations personnel physically separated fromdata center facilities.
For the unfortunate few that are trying to stretch out more life from their existing aging data centers,the speakers offered this advice:
Build only what you need
Decommission orphaned servers and storage, which can be 1 to 12 percent of your operations
Target for replacement any hardware over five years old, not just to reduce maintenance costs, butalso to get more energy-efficient equipment.
Consider moving test workloads, and as much as half of your web servers, off UPS and onto the nativeelectricity grid. In the event of an outage, this reduces UPS consumption.
Implement power-capping and load-shedding, especially during peak times.
Enacting these changes can significantly improve the bottom line. Archaic data centers, those typically over 10 years old with power usage effectiveness (PUE) over 3.0 can cost over twice as much as a moreefficient data center. To learn more about PUE as a metric, see the Green Grid's whitepaper[Data Center power efficiency metrics:PUE and DCiE].
While virtualization can help with these issues, it also introduces new problems, such as VM sprawl anddealing with antiquated licensing schemes of software companies.
The Four Traits of the World's Best-Performing Business Leaders
Best-selling author Jason Jennings presented his findings in researching his various books:
It's Not the Big That Eat the Small... It's the Fast That Eat the Slow : How to Use Speed as a Competitive Tool in Business
Less Is More : How Great Companies Use Productivity As a Competitive Tool in Business
Think Big, Act Small
Hit the Ground Running : A Manual for New Leaders
Jason identified the best companies and interviewed their leaders, including such companies as Koch Industries, Nucor Steel, and IKEA furniture. The leaders he interviewed felt a calling to serveas stewards of their companies, not just write mission and vision statements, and be willingto let go of projects or people that aren't working out.
Jasonindicated a 2007 Gallup poll on the American workplace indicates that 70 percent of employees do notfeel engaged in their jobs.The focus of these leaders isto hire people with the right attitudes, rather than the right aptitudes, and give those people with the knowledge and the right to make business decisions. If done well,employees will think and act as owners, and hold themselves accountable for their economic results. Jason found cases where 25-year-olds were givenresponsibility to make billion-dollar decisions!
I found his talk inspiring! The audience felt motivated to do their jobs better, and be more engagedin the success of their companies.
These keynote sessions set the mood for the rest of the week. I can tell already that the speakers willtoss out a large salad of buzzwords and IT industry acronyms. I saw several people in the audience confusedon some of the terminology, and hopefully they will come over to IBM booth 20 at the Solutions Expofor straight talk and explanation.
Today in the USA, we honor [Martin Luther King, Jr.] This year marks the 50th anniversary of the largest political demonstration to date in American history. Over 250,000 people went to Washington DC to hear Dr. King give his now famous "I have a dream" speech.
"IBM says revenue for its mainframe business rose 32% in the second quarter compared with a year earlier, easily outpacing overall sales growth of 13%.A big driver was February's launch of IBM's next-generation mainframe line, the z10, its first big upgrade since 2004. IBM spent about $1.5 billion on the new line.
With their power and size, mainframes have some unique advantages over (distributed) servers. Many companies cobble together many servers, powered by industry standard chips made by Intel (INTC) and Advanced Micro Devices, (AMD) to do jobs that were once the province of mainframes. IBM, too, sells such servers.
IBD: Can you tell me more about this business?
Gelardi: Traditionally, the mainframe was the back-office powerhouse for batch and transactional processing — sort of the thing behind banks, the thing behind retailers, the thing behind insurance companies.
It's the thing that, if you screw this up, you just gave your whole business away. The new thing, which is really sort of the second driver of growth, is the introduction of Linux (an open-source operating system popular with some servers) on the mainframe. Z-Linux (IBM's Linux mainframe software) is where we have been able to drive substantially new workloads to the mainframe.
IBD: Why is the mainframe business important to IBM?
Gelardi: It's a very differentiated product environment where we feel very confident that we can say to a client, look, we built this thing from the casters all the way up; the software stack, all the way up. We've built into this a level of performance and scalability and efficiency. We're very, very confident that we can resolve any issue (for customers).
Let me give you an example. If I take (1,500 Intel) servers . . . and put them on a single mainframe, I'll have no performance problems whatsoever. But I'm taking all of that workload that was on 1,500 separate servers and consolidating them on one mainframe. While it may be a million-dollar machine and up, it's actually cheaper than those 1,500 servers.
IBD: What are some big drivers for your clients today?
Gelardi: Energy. If you look at a workload on a previous generation mainframe, z9, for the equivalent performance on a z10, I'm going to use 15% less energy for the same amount of performance.
Look at the (physical data-center space) in the industry. The question used to be, "How much space do you want?" The question now is, "How much energy are you going to consume?" It's more efficient to manage the work loads inside the larger (mainframe).
IBD: So, you're saying that using a mainframe addresses these modern problems better than servers?
IBD: Is it hard to convince people of that?
Gelardi: It's a legitimate question for clients who never had a mainframe. There are a few. (In those cases) it will probably be more complicated (to convince them).
However, a year or so ago we put out a press release about an entertainment (company). Their story was, "We're going to build a new gaming environment." Long story short, they said, "Why not use the mainframe?" There are new clients coming to the mainframe.
IBD: Do mainframes help other IBM businesses?
Gelardi: Clearly. I have very broad coverage. We are the server vendor. We have the storage capacity; we have the operating environment; we have the software stack, (including) Websphere, Tivoli, DB2. We have the services capabilities. We have the consulting capability. You can sort of go on. It becomes an ecosystem that is really valuable to the company at large.
IBD: What mainframe customers were active in the second quarter?
Gelardi: Interesting enough (given the state of the industry), the financial services sector was very strong. That was particularly true in the Americas and in Europe. We have a pretty broad spread (of users), but there is no question that financial services is a core market."

Hey everyone, I'm having a great time in New York.
Here are a few webinars this week you might be interested in, related to tape, and tape encryption:
1) Wednesday If regulatory compliance and protecting your data against security breaches is top of mind for you, I invite you to attend a webinar on a new enterprise encryption solution from IBM featuring the IBM System Storage™ TS1120 tape drive. On September 20, 2006 Jon Oltsik, Senior Analyst for Information Security with the Enterprise Strategy Group, will moderate a discussion on IBM’s encryption strategy and latest data security advances with a panel of our product and industry experts.
This week I am off to Budapest, Hungary, for business meetings. It is the closest major city to IBM'smanufacturing plant in a small town called Vac (rhymes with "knots") where the IBM System Storage DS8000 seriesand SAN Volume Controller are assembled.
Soon, the U.S. is switching on-air television signals from analog to digital format. The switch-over happensFebruary 17, 2009. According to the [Federal Communications Commission], Americans haveuntil this Monday, March 31, to request up to two 40-dollar coupons towards the purchase of digital-to-analog converter boxesso that the on-air digital signals can be used with existing analog-only television equipment.
(For my readers outside the United States, a bit of background explanation may be necessary. Americans consider access to television a self-evident and unalienable right.According to a Pew Research report[Luxury or Necessity?] 64 percent of Americansconsider a television set a necessity, and 33 percent consider paid providers, like cable or satellite, a necessity.Even prisoners in U.S. jails are allowed to watch television!)
Taking advantage of the "Y2K crisis" like nature of this 2/17/2009 deadline, paid providers have been advertisingthat this deadline only applies to on-air customers. Those who have cable or satellite can continue to use theiranalog equipment. I have been a subscriber for Cox Cable for some time, and my parents recently made the switchas well. Two weeks ago, however, my parents called me in a panic. Cox Cable chose to move one channel, TurnerClassic Movies (TCM), over from their analog line-up over to their digital line-up. They thought this wasn't goingto happen until 2/17/2009! They asked me to investigate and provide them alternative options.
I spoke to a Cox Cable representative.
Did Turner force Cox Cable to do this? Did they digitize their entire collection of movies? No, Cox Cable is choosing to send the TCM signal over the digital bandwidth, and they are converted back to analog by their set-top box.
Do customers who now get one less channel get a discount? No, same price, less service.
Why move a single channel over? Eventually, everything is going digital, and this is a small "baby step" to getpeople to switch over.
But TCM is a collection of grainy, black-and-white movies from the 1950s and 1960s, it is probably the channelthat gets the least benefit to convert to digital. Why choose TCM specifically? TCM is "commercial-free" so providesno additional revenue opportunity. Moving this to digital frees up an analog channel to run a new "on demand" servicethat could generate additional revenue for Cox Cable.
What would it take in terms of additional cost and equipment to watch the TCM in digital?A set-top digital box from Cox Cable, which costs one-time 10 dollars to install by a professional technician, plus 11 dollars per month for the extra "service" provided.
Do I need a High-Def television set or other equipment? No, the digital signal for TCM is standard format, so no HD equipment required.
I currently split my cable signal, so that I can watch one channel and record another, or record two separate channels at the same time, using a standard format VCR and Tivo, can I continue to do this with the digital set-top box? Yes, absolutely.
I decided to give it a try, and a technician was scheduled to perform the installation last Sunday, which was Easter holiday for some people. The technician was able to connect the set-top box directly to my television set, but thesignal is converted to a single "Channel 3", forcing the use of a separate Cox Cable remote control unit to set the channel on the set-top box. He set the set-top box to TCM (channel 199) and showed that the TCM channel was now available again.
How would my VCR or Tivo record anything? You have to set the set-top box manually to the appropriate channel desired, then set the VCR or Tivo to record "Channel 3".
How would I record one channel while watching another? That does not appear possible with this set-top box. If we split before entering the set-top box, then that equipment would get the analog channels only, not TCM.
How about recording two different channels concurrently? No way.
I feel bad for the technician. He spent two hours on his Easter Sunday to install service that I was told by theirsales rep would work with my equipment, only to find out it won't and he ended up having to take it all back out andcancel the work order. He doesn't even get paid overtime for this.
So, I am back to where I was before, analog channels minus the TCM channel. However, the lesson is clear, eventuallyeverything is going to digital, and people may not realize what this means to them.
Well it's Tuesday again, and you know what that means? IBM Announcements!
You might be thinking, didn't IBM just have a [huge storage announcement October 8, 2013]? You would be right! IBM's $1B additional investment in Storage has been like shot of adrenaline in getting new features and functions out sooner to our clients.
DS8870 Disk System Release 7.2
New IBM POWER7+ controllers. The previous models of DS8870 were based on the POWER7 controllers, and these new models have POWER7+ processors. This change enhances the performance across the board, from mainframe to distributed systems, from sequential to random. Customers with existing POWER7-based models will be able to do MES upgrade to the new POWER7+ next year.
For comparison with older DS8000 models, here are some internal IBM measurements we took for Database workloads on both z/OS(mainframe) and Distributed systems with typical 70% read, 30% write and 50% cache hit:
IBM Internal Measurements (thousands of IOPS)
DB Distributed systems
New 1.2TB (10K RPM) and 4TB (7200 RPM) self-encrypting enterprise drives (SED). This is a 33% boost over the previous 900GB and 3TB drives previously available. As with all the other drives in the DS8870, these new drives include the encryption chip right on the drive itself, offering encryption with scalability.
Improved security. Release 7.2 will support the U.S. National Institute of Standards and Technology [NIST.gov]] 800-131A specification, raising the 96-bit encryption to the required 112 bits on the customer IP network. This involves updates to the security firmware, management software and digital signatures on code loads.
Metro Mirror enhancement for System z. By avoiding serial conflicts of updated blocks, this enhancement can boost performance up to 100 percent when using Metro Mirror with z/OS applications on System z mainframes.

All-Flash Optimization. Yesterday, in my post [IBM FlashSystem versus EMC XtremeIO], I mentioned that any hybrid systems like the IBM Storwize V7000 that can support a mix of SSD and HDD can obviously be configured as SSD-only. Apparently, that was not obvious to many readers, so I apologize. For the DS8870, you can configure an all-Flash (SSD only) configuration, and Release 7.2 added some optimization when configured with SSD only.
1,056 drives 15K @146GB in RAID-10
224 drives SSD @400GB in RAID-5
Same - Usable 72 TB
70 percent faster
33 percent less floor space required
62 percent less energy consumed
(Note: Performance results based on measurements and projections using IBM benchmarks in a controlled environment.)
OpenStack™ support DS8870 now offers the [OpenStack Cinder] interface for block LUN allocations in OpenStack environments. IBM is a Platinum sponsor of OpenStack, and Opentack is the strategic platform for IBM private and hybrid clouds.
XIV Storage System
Following on the heels of the [XIV enhancements announced], IBM has now added 800GB Solid State Drives (SSD) as Read cache for its 4TB drive-based models.
DCS3860 Disk System
The DCS3860 is the next generation of the DCS3700 disk system. Designed with Linux-x86 servers in mind, the system offers direct SAS host attachement, 24GB of cache, and 60 drives in a compact 4U drawer. Like its predecessor, the drives are stored on five pull-out trays, with twelve hot-swappable drives per tray. You can add up to five more expansion units, with 60 drives each, for a total of 360 drives in 24U rack space.
These new models will help our clients deploy new workloads and consolidate existing workloads.
