Wrapping up my coverage of the annual [2010 System Storage Technical University], I attended what might be perhaps the best session of the conference. Jim Nolting, IBM Semiconductor Manufacturing Engineer, presented the new IBM zEnterprise mainframe, "A New Dimension in Computing", under the Federal track.
The zEnterprises debunks the "one processor fits all" myth. For some I/O-intensive workloads, the mainframe continues to be the most cost-effective platform. However, there are other workloads where a memory-rich Intel or AMD x86 instance might be the best fit, and yet other workloads where the high number of parallel threads of reduced instruction set computing [RISC] such as IBM's POWER7 processor is more cost-effective. The IBM zEnterprise combines all three processor types into a single system, so that you can now run each workload on the processor that is optimized for that workload.
IBM zEnterprise z196 Central Processing Complex (CPC)
Let's start with the new mainframe z196 central processing complex (CPC). Many thought this would be called the z11, but that didn't happen. Basically, the z196 machine has a maximum 96 cores versus z10's 64 core maximum, and each core runs 5.2GHz instead of z10's cores running at 4.7GHz. It is available in air-cooled and water-cooled models. The primary operating system that runs on this is called "z/OS", which when used with its integrated UNIX System Services subsystem, is fully UNIX-certified. The z196 server can also run z/VM, z/VSE, z/TPF and Linux on z, which is just Linux recompiled for the z/Architecture chip set. In my June 2008 post [Yes, Jon, there is a mainframe that can help replace 1500 servers], I mentioned the z10 mainframe had a top speed of nearly 30,000 MIPS (Million Instructions per Second). The new z196 machine can do 50,000 MIPS, a 60 percent increase!
The z196 runs a hypervisor called PR/SM that allows the box to be divided into dozens of logical partitions (LPAR), and the z/VM operating system can also act as a hypervisor running hundreds or thousands of guest OS images. Each core can be assigned a specialty engine "personality": GP for general processor, IFL for z/VM and Linux, zAAP for Java and XML processing, and zIIP for database, communications and remote disk mirroring. Like the z9 and z10, the z196 can attach to external disk and tape storage via ESCON, FICON or FCP protocols, and through NFS via 1GbE and 10GbE Ethernet.
IBM zEnterprise BladeCenter Extension (zBX)
There is a new frame called the zBX that basically holds two IBM BladeCenter chassis, each capable of 14 blades, so total of 28 blades per zBX frame. For now, only select blade servers are supported inside, but IBM plans to expand this to include more as testing continues. The POWER-based blades can run native AIX, IBM's other UNIX operating system, and the x86-based blades can run Linux-x86 workloads, for example. Each of these blade servers can run a single OS natively, or run a hypervisor to have multiple guest OS images. IBM plans to look into running other POWER and x86-based operating systems in the future.
If you are already familiar with IBM's BladeCenter, then you can skip this paragraph. Basically, you have a chassis that holds 14 blades connected to a "mid-plane". On the back of the chassis, you have hot-swappable modules that snap into the other side of the mid-plane. There are modules for FCP, FCoE and Ethernet connectivity, which allows blades to talk to each other, as well as external storage. BladeCenter Management modules serve as both the service processor as well as the keyboard, video and mouse Local Console Manager (LCM). All of the IBM storage options available to IBM BladeCenter apply to zBX as well.
Besides general purpose blades, IBM will offer "accelerator" blades that will offload work from the z196. For example, let's say an OLAP-style query is issued via SQL to DB2 on z/OS. In the process of parsing the complicated query, it creates a Materialized Query Table (MQT) to temporarily hold some data. This MQT contains just the columnar data required, which can then be transferred to a set of blade servers known as the Smart Analytics Optimizer (SAO), then processes the request and sends the results back. The Smart Analytics Optimizer comes in various sizes, from small (7 blades) to extra large (56 blades, 28 in each of two zBX frames). A 14-blade configuration can hold about 1TB of compressed DB2 data in memory for processing.
IBM zEnterprise Unified Resource Manager
You can have up to eight z196 machines and up to four zBX frames connected together into a monstrously large system. There are two internal networks. The Inter-ensemble data network (IEDN) is a 10GbE that connects all the OS images together, and can be further subdivided into separate virtual LANs (VLAN). The Inter-node management network (INMN) is a 1000 Mbps Base-T Ethernet that connects all the host servers together to be managed under a single pane of glass known as the Unified Resource Manager. It is based on IBM Systems Director.
By integrating service management, the Unified Resource Manager can handle Operations, Energy Management, Hypervisor Management, Virtual Server Lifecycle Management, Platform Performance Management, and Network Management, all from one place.
IBM Rational Developer for System z Unit Test (RDz)
But what about developers and testers, such as those Independent Software Vendors (ISV) that produce mainframe software. How can IBM make their lives easier?
Phil Smith on z/Journal provides a history of [IBM Mainframe Emulation]. Back in 2007, three emulation options were in use in various shops:
Open Mainframe, from Platform Solutions, Inc. (PSI)
FLEX-ES, from Fundamental Software, Inc.
Hercules, which is an open source package
None of these are viable options today. Nobody wanted to pay IBM for its Intellectual Property on the z/Architecture or license the use of the z/OS operating system. To fill the void, IBM put out an officially-supported emulation environment called IBM System z Professional Development Tool (zPDT) available to IBM employees, IBM Business Partners and ISVs that register through IBM Partnerworld. To help out developers and testers who work at clients that run mainframes, IBM now offers IBM Rational Developer for System z Unit Test, which is a modified version of zPDT that can run on a x86-based laptop or shared IBM System x server. Based on the open source [Eclipse IDE], the RDz emulates GP, IFL, zAAP and zIIP engines on a Linux-x86 base. A four-core x86 server can emulate a 3-engine mainframe.
With RDz, a developer can write code, compile and unit test all without consuming any mainframe MIPS. The interface is similar to Rational Application Developer (RAD), and so similar skills, tools and interfaces used to write Java, C/C++ and Fortran code can also be used for JCL, CICS, IMS, COBOL and PL/I on the mainframe. An IBM study ["Benchmarking IDE Efficiency"] found that developers using RDz were 30 percent more productive than using native z/OS ISPF. (I mention the use of RAD in my post [Three Things to do on the IBM Cloud]).
What does this all mean for the IT industry? First, the zEnterprise is perfectly positioned for [three-tier architecture] applications. A typical example could be a client-facing web-server on x86, talking to business logic running on POWER7, which in turn talks to database on z/OS in the z196 mainframe. Second, the zEnterprise is well-positioned for government agencies looking to modernize their operations and significantly reduce costs, corporations looking to consolidate data centers, and service providers looking to deploy public cloud offerings. Third, IBM storage is a great fit for the zEnterprise, with the IBM DS8000 series, XIV, SONAS and Information Archive accessible from both z196 and zBX servers.
This week, July 26-30, 2010, I am in Washington DC for the annual [2010 System Storage Technical University]. As with last year, we have joined forces with the System x team. Since we are in Washington DC this time, IBM added a "Federal Track" to focus on government challenges and solutions. So, basically, offering attendees the option to attend three conferences for one low price.
This conference was previously called the "Symposium", but IBM changed the name to "Technical University" to emphasize the technical nature of the conference. No marketing puffery like "Journey to the Private Cloud" here! Instead, this is bona fide technical training, qualifying attendees to count this towards their Continuing Professional Education (CPE).
(Note to my readers:The blogosphere is like a playground. In the center are four-year-olds throwing sand into each other's faces, while mature adults sit on benches watching the action, and only jumping in as needed. For example, fellow blogger Chuck Hollis (EMC) got sand in his face for promising to resign if EMC ever offered a tacky storage guarantee, and then [failed to follow through on his promise] when it happened.
Several of my readers asked me to respond to another EMC blogger's latest [fistful of sand].
A few months ago, fellow blogger Barry Burke (EMC) committed to [stick to facts] in posts on his Storage Anarchist blog. That didn't last long! BarryB apparently has fallen in line with EMC's over-promise-then-under-deliver approach. Unfortunately, I will be busy covering the conference and IBM's robust portfolio of offerings, so won't have time to address BarryB's stinking pile of rumor and hearsay until next week or later. I am sorry to disappoint.)
This conference is designed to help IT professionals make their business and IT infrastructure more dynamic and, in the process, help reduce costs, mitigate risks, and improve service. This technical conference event is geared to IT and Business Managers, Data Center Managers, Project Managers, System Programmers, Server and Storage Administrators, Database Administrators, Business Continuity and Capacity Planners, IBM Business Partners and other IT Professionals. This week will offer over 300 different sessions and hands-on labs, certification exams, and a Solutions Center.
For those who want a quick stroll through memory lane, here are my posts from past events:
In keeping up with IBM's leadership in Social Media, IBM Systems Lab Services and Training team running this event have their own [Facebook Fan Page] and
[blog]. IBM Technical University has a Twitter account [@ibmtechconfs], and hashtag #ibmtechu. You can also follow me on Twitter [@az990tony].
Bill Bauman, IBM System x Field Technical Support Specialist and System x University celebrity, presented the differences between Grid, SOA and Cloud Computing. I thought this was an odd combination to compare and contrast, but his presentation was well attended.
Grid - this is when two or more independently owned and managed computers are brought together to solve a problem. Some research facilities do this. IBM helped four hospitals connect their computers together into a grid to help analyze breast cancer. IBM also supports the [World Community Grid] which allows your personal computer to be connected to the grid and help process calculations.
SOA - SOA, which stands for Service Oriented Architecture, is an approach to building business applications as a combination of loosely-coupled black-box components orchestrated to deliver a well-defined level of service by linking together business processes. I often explain SOA as the the business version of Web 2.0. You can download a free copy of the eBook "SOA for Dummies" at the [IBM Smart SOA] landing page.
Cloud - A Cloud is a dynamic, scalable, expandable, and completely contractible architecture. It may consist of multiple, disparate, on-premise and off-premise hardware and virtualized platforms hosting legacy, fully installed, stateless, or virtualized instances of operating systems and application workloads.
Tom Vezina, IBM Advanced Technical Sales Specialist, presented "Chaos to Cloud Computing". Survey results show that roughly 70 percent of cloud spend will be for private clouds, and 30 percent for public, hybrid or community clouds. Of the key motivations for public cloud, 77 percent or respondents cited reducing costs, 72 percent time to value, and 50 percent improving reliability.
Tom ran over 500 "server utilization" studies for x86 deployments during the past eight years. Of these, the worst was 0.52 percent CPU utilization, the best was 13.4 percent, and the average was 6.8 percent. When IBM mentions that 85 percent of server capacity is idle, it is mostly due to x86 servers. At this rate, it seems easy to put five to 20 guest images onto a machine. However, many companies encounter "VM stall" where they get stuck after only 25 percent of their operating system images virtualized.
He feels the problem is with the fact most Physical-to-Virtual (P2V) migrations are manual efforts. There are tools available like Novell [PlateSpin Recon] to help automate and reduce the total number of hours spent per migration.
System x KVM Solutions
Boy, I walked into this one. Many of IBM's cloud offerings are based on the Linux hypervisor called Kernel-based Virtual Machine [a href="http://www.linux-kvm.org/page/Main_Page">KVM] instead of VMware or Microsoft Hyper-V. However, this session was about the "other KVM": keyboard video and mouse switches, which thankfully, IBM has renamed to Console Managers to avoid confusion. Presenters Ben Hilmus (IBM) and Steve Hahn (Avocent) presented IBM's line of Local Console Managers (LCM) and Global Console Managers (GCM) products.
LCM are the traditional KVM switches that people are familiar with. A single keyboard, video and mouse can select among hundreds of servers to perform maintenance or check on status. GCM adds KVM-over-IP capabilities, which means that now you can access selected systems over the Ethernet from a laptop or personal computer. Both LCM and GCM allow for two-level tiering, which means that you can have an LCM in each rack, and an LCM or GCM that points to each rack, greatly increasing the number of servers that can be managed from a single pane of glass.
Many severs have a "service processor" to manage the rest of the machine. IBM RSA II, HP iLO, and Dell DRAC4 are some examples. These allow you to turn on and off selected servers. IBM BladeCenter offers an Management Module that allows the chassis to be connected to a Console Manager and select a specific blade server inside. These can also be used with VMware viewer, Virtual Network Computing (VNC), or Remote Desktop Protocol (RDP).
IBM's offerings are unique it that you can have an optical CD/DVD drive or USB external storage attached at the LCM or GCM, and make it look like the storage is attached to the selected server. This can be used to install or upgrade software, transfer log files, and so on. Another great use, and apparently the motivation for having this session in the "Federal Track", is that the USB can be used to attach a reader for a smart card, known as a Common Access Card [CAC] used by various government agencies. This provides two-factor authentication [TFA]. For example, to log into the system, you enter your password (something you know) and swipe your employee badge smart card (something you have). The combination are validated at the selected server to provide access.
I find it amusing that server people limit themselves to server sessions, and storage people to storage sessions. Sometimes, you have to step "outside your comfort zone" and learn something new, something different. Open your eyes and look around a bit. You might just be surprised what you find.
(FTC note: I work for IBM. IBM considers Novell a strategic Linux partner. Novell did not provide me a copy of Platespin Recon, I have no experience using it, and I mention it only in context of the presentation made. IBM resells Avocent solutions, and we use LCM gear in the Tucson Executive Briefing Center.)
Continuing my week in Washington DC for the annual [2010 System Storage Technical University], I presented a session on Storage for the Green Data Center, and attended a System x session on Greening the Data Center. Since they were related, I thought I would cover both in this post.
Storage for the Green Data Center
I presented this topic in four general categories:
Drivers and Metrics - I explained the three key drivers for consuming less energy, and the two key metrics: Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCiE).
Storage Technologies - I compared the four key storage media types: Solid State Drives (SSD), high-speed (15K RPM) FC and SAS hard disk, slower (7200 RPM) SATA disk, and tape. I had comparison slides that showed how IBM disk was more energy efficient than competition, for example DS8700 consumes less energy than EMC Symmetrix when compared with the exact same number and type of physical drives. Likewise, IBM LTO-5 and TS1130 tape drives consume less energy than comparable HP or Oracle/Sun tape drives.
Integrated Systems - IBM combines multiple storage tiers in a set of integrated systems managed by smart software. For example, the IBM DS8700 offers [Easy Tier] to offer smart data placement and movement across Solid-State drives and spinning disk. I also covered several blended disk-and-tape solutions, such as the Information Archive and SONAS.
Actions and Next Steps - I wrapped up the talk with actions that data center managers can take to help them be more energy efficient, from deploying the IBM Rear Door Heat Exchanger, or improving the management of their data.
Greening of the Data Center
Janet Beaver, IBM Senior Manager of Americas Group facilities for Infrastructure and Facilities, presented on IBM's success in becoming more energy efficient. The price of electricity has gone up 10 percent per year, and in some locations, 30 percent. For every 1 Watt used by IT equipment, there are an additional 27 Watts for power, cooling and other uses to keep the IT equipment comfortable. At IBM, data centers represent only 6 percent of total floor space, but 45 percent of all energy consumption. Janet covered two specific data centers, Boulder and Raleigh.
At Boulder, IBM keeps 48 hours reserve of gasoline (to generate electricity in case of outage from the power company) and 48 hours of chilled water. Many power outages are less than 10 minutes, which can easily be handled by the UPS systems. At least 25 percent of the Computer Room Air Conditioners (CRAC) are also on UPS as well, so that there is some cooling during those minutes, within the ASHRAE guidelines of 72-80 degrees Fahrenheit. Since gasoline gets stale, IBM runs the generators once a month, which serves as a monthly test of the system, and clears out the lines to make room for fresh fuel.
The IBM Boulder data center is the largest in the company: 300,000 square feet (the equivalent of five football fields)! Because of its location in Colorado, IBM enjoys "free cooling" using outside air temperature 63 percent of the year, resulting in a PUE of 1.3 rating. Electricity is only 4.5 US cents per kWh. The center also uses 1 Million KwH per year of wind energy.
The Raleigh data center is only 100,000 Square feet, with a PUE 1.4 rating. The Raleigh area enjoys 44 percent "free cooling" and electricity costs at 5.7 US cents per kWh. The Leadership in Energy and Environmental Design [LEED] has been updated to certify data centers. The IBM Boulder data center has achieved LEED Silver certification, and IBM Raleigh data center has LEED Gold certification.
Free cooling, electricity costs, and disaster susceptibility are just three of the 25 criteria IBM uses to locate its data centers. In addition to the 7 data centers it manages for its own operations, and 5 data centers for web hosting, IBM manages over 400 data centers of other clients.
It seems that Green IT initiatives are more important to the storage-oriented attendees than the x86-oriented folks. I suspect that is because many System x servers are deployed in small and medium businesses that do not have data centers, per se.
Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.
What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.
How do I evaluate IBM storage solutions in regards to [PCI-DSS] 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 week in Washington DC for the annual [2010 System Storage Technical University], here is my quick recap of the keynote sessions presented Monday morning. Marlin Maddy, Worldwide Technical Events Executive for IBM Systems Lab Services and Training, served as emcee.
Jim Northington, IBM System x Business Line Executive, covered the IT industry's "Love/Hate Relationship" with x86 platform. Many of the physical limitations that were previously a pain on this platform are now addressed, through a combination of IBM's new innovative eX5 architecture and virtualization technologies.
Jim also presented the [IBM CloudBurst] solution. IBM CloudBurst is one of the many "Integrated Systems" designed to help simplify deployment. Based on IBM BladeCenter, the IBM CloudBurst is basically a Private Cloud rack for those that are ready to deploy in their own data center.
Jim feels that server virtualization on x86 platforms is still in its infancy. IBM calls it the 70/30 rule: 70 percent of x86 workloads are running virtualized on 30 percent of the physical servers.
Maria Azua, IBM Vice President of Cloud Computing Enablement, presented on Cloud Computing. Technology is being adopted at faster rates. It took 40 years for radio to get 60 million listeners, 20 years for 60 million television viewers, 3 years to get 60 million surfers on the Internet, but it only took 4 months to get 60 million players on Farmville!
Maria covered various aspects of Cloud Computing: virtualization images, service catalog, provisioning elasticity, management and billing services, and virtual networks. With Cloud Computing, the combination of virtualization technologies, standardization, and automation can reduce costs and improve flexibility.
We've seen this happen before. Telcos transitioned from human operators to automated digital switches. Manufacturers went from having small teams of craftsmen to assembly lines of robots. Banks went from long lines of bank tellers to short lines at the ATM.
Maria said that companies are faced with three practical choices:
Do-it-Yourself, buy the servers, storage and switches and connect everything together.
Purchase pre-installed "integrated systems" to simplify deployment.
Subscribe to Cloud computing, allowing a service provider do all this for you.
In countries where network access is not ubiquitous, IBM has developed tools for the cloud that work in "offline" mode. IBM has also developed or modified tools to run better in the cloud. Launching a computer instance from the cloud from the service catalog is so easy to do, your 5-year-old child can do this!
Want to see Cloud Computing in action? Check out [Innovation.ed.gov], which is run in the IBM cloud, for the US Department of Education's website to foster innovation.
Whether you adopt public, private or a hybrid cloud computing approach, Maria suggests you take time to plan, test your applications for standardization, examine all risks, and explore new workloads that might be good candidates. Otherwise, moving to the cloud might just mean "More mess for less". Maria provided a list of applications that IBM considers good fit for Cloud Computing today.
I heard several audience members indicate that this is the first time someone finally explained Cloud Computing to them in a way that made sense!
Continuing my week in Washington DC for the annual [2010 System Storage Technical University], here is my quick recap of the keynote sessions presented Monday morning. Marlin Maddy, Worldwide Technical Events Executive for IBM Systems Lab Services and Training, served as emcee.
Roland Hagan, IBM Vice President for IBM System x server platform, presented on how IBM is redefining the x86 computing experience. More than 50 percent of all servers are x86 based. These x86 servers are easy to acquire, enjoy a large application base, and can take advantage of readily available skilled workforce for administration. The problem is that 85 percent of x86 processing power remains idle, energy costs are 8 times what they were 12 years ago, and management costs are now 70 percent of the IT budget.
IBM has the number one market share for scalable x86 servers. Roland covered the newly announced eX5 architecture that has been deployed in both rack-optimized models as well as IBM BladeCenter blade servers. These can offer 2x the memory capacity as competitive offerings, which is important for today's server virtualization, database and analytics workloads. This includes 40 and 80 DIMM models of blades, and 64 to 96 DIMM models of rack-optimized systems. IBM also announced eXFlash, internal Solid State Drives accessible at bus speeds. FlexNode allows a 4-node system to dynamically change to 2 separate 2-node systems.
By 2013, analysts estimate that 69 percent of x86 workloads will be virtualized, and that 22 percent of servers will be running some form of hypervisor software. By 2015, this grows to 78 percent of x86 workloads being virtualized, and 29 percent of servers running hypervisor.
Doug Balog, IBM Vice President and Disk Storage Business Line Executive, presented how the growth of information results in a "perfect storom" for the storage industry. Storage Admins are focused on managing storage growth and the related costs and complexity, proper forecasting and capacity planning, and backup administration. IBM's strategy is to help clients in the following areas:
Storage Efficiency - getting the most use out of the resources you invest
Service Delivery - ensuring that information gets to the right people at the right time, simplify reporting and provisioning
Data Protection - protecting data against unethical tampering, unauthorized access, and unexpected loss and corruption
He wrapped up his talk covering the success of DS8700 and XIV. In fact, 60 percent of XIV sales are to EMC customers. The TCO of an XIV is less than half the TCO of a comparable EMC VMAX disk system.
Dave McQueeney, IBM Vice President for Strategy and CTO for US Federal, covered how IBM's Smarter Planet vision for smarter cities, smarter healthcare, smarter energy grid and smarter traffic are being adopted by the public sector. Almost every data center in US Federal government is out of power, floor space and/or cooling capability. An estimated 80 percent of US Federal government IT budgets are spent on maintenance and ongoing operations, leaving very little left over for the big transformational projects that President Barack Obama wants to accomplish.
Who has the most active Online Transaction Processing (OLTP)? You might guess a big bank, but it is the US Department of Homeland Security (DHS), with a system processing 600 million transactions per day. Another government agency is #2, and the top Banking application is finally #3. The IBM mainframe has solved problems 10 to 15 years ago that the distributed systems are just now encountering today. Worldwide, more than 80 percent of banks use mainframes to handle their financial transactions.
IBM's recent POWER7 set of servers are proving successful in the field. For example, Allianz was able to consolidate 60 servers to 1. Running DB2 on POWER7 server is 38 percent less expensive than Oracle on x86 Nehalem processors. For Java, running JVM on POWER7 is 73 percent better than JVM on x86 Nehalem.
The US federal government ingests a large amount of data. It has huge 10-20 PB data warehouses. In fact, the amount of GB received every year by the US federal government alone exceed the production of all disk drives produced by all drive manufacturers. This means that all data must be processed through "data reduction" or it is gone forever.
The last keynote for Monday was given by Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist for System Storage. He started out shocking the audience with his view that the "disk drive industry is a train wreck". While R&D in disk drives enjoyed a healthy improvement curve up to about 2004, it has now slowed down, getting more difficult and more expensive to improve performance and capacity of disk drives. The rest of his presentation was organized around three themes:
Integrated Stacks - while new-comers like Oralce/Sun and the VCE coalition are promoting the benefits of integrated stacks, IBM has been doing this for the past five decades. New advancements in Server and Storage virtualization provide exciting new opportunities.
Integrated Systems - solutions like IBM Information Archive and SONAS, and new features like Easy Tier that help adopt SSD transparently. As it gets harder and harder to scale-up, IBM has moved to innovative scale-out architectures.
Integrated Data Center management - companies are now realizing that management and governance are critical factors of success, and that this needs to be integrated between traditional IT, private, public and hybrid cloud computing.
This was a great inspiring start for what looks like an awesome week!
I was in Hollywood Florida for the IBM Systems Technical University. Here is my recap of the final two days, day 4 and 5.
The Pendulum Swings Back: Understanding Converged and Hyperconverged Systems
Once again, I presented my popular session on converged and hyperconverged systems. For converged, IBM offers IBM PureApplication systems with Power and x86 servers, as well as partnership with Cisco called VersaStack. Both support IBM Cloud Private as a platform for running applications.
For Hyperconverged, IBM offers Spectrum Accelerate and Spectrum Scale, as well as partnerships with SuperMicro that combines Spectrum Accelerate on SuperMicro x86 servers, and partnership with Nutanix for CS-models of Power servers pre-installed with Nutanix software.
Unlike other converged and hyperconverged solutions that act as isolated islands of compute and storage, IBM's solutions can be incorporated into an existing datacenter with IBM Cloud Private for orchestration, and IBM Spectrum Scale to provide common access to data.
The Seven Tiers of Business Continuity and Disaster Recovery
With all the natural disasters that happened last year in the USA, and the more recent ones all over the world, this session continues to draw a crowd.
The seven tiers range from the least expensive to most expensive. The least expensive involves restoring data from tapes stored in an offsite vault. Tape continues to be the least expensive storage medium, and can be used to bring up a company in a few days.
For faster recovery, there are options like electronic vaulting to virtual tape libraries, and now the use of Cloud storage for ubiquitous access to data from different locations.
Snapshots of entire volumes, virtual machines or databases are also quite popular. IBM offers IBM Spectrum Protect Snapshot, Spectrum Protect Plus, and Spectrum Copy Data Management for this.
Faster recovery is possible with remote mirroring. This involves sending all of the updates to a secondary location. In the event of a disaster, clients can switch processing with the data already there. IBM has over 800 clients able to do just that in less than 30 minutes.
Event Night by the Pool

While Hurricane Michael raged in upper Florida the week prior, the event coordinators were a bit nervous to offer an evening dinner event by the pool, but the weather cooperated!

I was a social butterfly, moving from table to table to talk to all of the various attendees. A light breeze and excellent food and music made for an enjoyable night!
The pool reception went on to about 10:00pm at night. IBM had lit up its logo into the pools for a great view from above. Perhaps just 30 minutes after arriving back to my hotel room, we had quite the thunderstorm! How incredibly lucky this did not happen during the event!
The following day, I presented my session on "Managing Risk with Data Footprint Reduction, a repeat of the session I did earlier that week.
This was a pleasant way to end the week! Aside from the heat and humidity being above average for October, it was a beautiful hotel in a lovely city.
