After my response to Jon Toigo on Drunken Data
withmy post [Elevenanswers about Deduplication
], Jon follows up with a request to validate the numbersquoted in the February 26 Press Release[IBM launches New “System z10” Mainframe
], particularly the estimate that a single mainframecan handle to the workload of 1500 x86 servers, in his post[A Bit More Blegging
]. The timing is perfect in that IBM launched[the next wave of Project Big Green
] today.To avoid sounding like an [editorial from the New York Sun
],I checked the facts, and spoke to the person in IBM who did all the calculations. Jon, as always, you have my permissionto publish this on your site if you want.
( I cannot take credit for coining the new term "bleg". I saw this term firstused over on the [FreakonomicsBlog]. If you have not yet read the book "Freakonomics", I highly recommend it! The authors' blog is excellent as well.)
For this comparison, it is important to figure out how much workload a mainframe can support, how much an x86 cansupport, and then divide one from the other. Sounds simple enough, right? And what workload should you choose?IBM chose a business-oriented "data-intensive" workload using Oracle database. (If you wanted instead a scientific"compute-intensive" workload, consider an [IBM supercomputer] instead, the most recent of which clocked in over 1 quadrillion floating point operations per second, or PetaFLOP.) IBM compares the following two systems:
- Sun Fire X2100 M2, model 1220 server (2-way)
IBM did not pick a wimpy machine to compare against. The model 1220 is the fastest in the series, with a 2.8Ghz x86-64 dual-core AMD Opteron processor, capable of running various levels of Solaris, Linux or Windows.In our case, we will use Oracle workloads running on Red Hat Enterprise Linux.All of the technical specifications are available at the[Sun Microsystems Sun Fire X1200] Web site.I am sure that there are comparable models from HP, Dell or even IBM that could have been used for this comparison.
- IBM z10 Enterprise Class mainframe model E64 (64-way)
This machine can run a variety of operating systems also, including Red Hat Enterprise Linux (RHEL). The E64 has four "multiple processor modules" called"processor books" for a total of 77 processing units: 64 central processors, 11 system assist processors (SAP) and 2 spares. That's right, spare processors, in case any others gobad, IBM has got your back. You can designate a central processor in a variety of flavors. For running z/VM and Linux operating systems, the central processors can be put into "Integrated Facility for Linux" (IFL) mode.On IT Jungle, Timothy Patrick Morgan explains the z10 EC in his article[IBM Launches 64-Way z10 Enterprise Class Mainframe Behemoth]. For more information on the z10 EC, see the 110-page [Technical Introduction], orread the specifications on the[IBM z10 EC] Web site.
Moving Oracle workloads from x86 over to mainframe is quite commonsince [IBM and Cisco joined forces to meet Linux On Mainframe demand]. For more information on consolidating x86 servers running Oracle over to a mainframe, read the [Quick Reference], IBMRedbook titled ["Using Oracle Solutionson Linux for System z"], or this [presentation by Jim Elliott, IBM System z Specialist].
In a shop full of x86 servers, there are production servers, test and development servers, quality assuranceservers, standby idle servers for high availability, and so on. On average, these are only 10 percent utilized.For example, consider the following mix of servers:
- 125 Production machines running 70 percent busy
- 125 Backup machines running idle ready for active failover in case a production machine fails
- 1250 machines for test, development and quality assurance, running at 5 percent average utilization
While [some might question, dispute or challenge thisten percent] estimate, it matches the logic used to justify VMware, XEN, Virtual Iron or other virtualization technologies. Running 10 to 20 "virtual servers" on a single physical x86 machine assumes a similar 5-10 percent utilization rate.
Note: The following paragraphs have been revised per comments received.
|Now the math. Jon, I want to make it clear I was not involved in writing the press release nor assisted with thesemath calculations. Please, don't shoot the messenger! Remember this cartoon where two scientists in white lab coats are writing mathcalculations on a chalkboard, and in the middle there is "and then a miracle happens..." to continue the rest ofthe calculations?|
In this case, the miracle is the number that compares one server hardware platform to another. I am not going to bore people with details like the number of concurrent processor threads or the differencesbetween L1 and L3 cache. IBM used sophisticated tools and third party involvement that I am not allowed to talk about, and I have discussed this post with lawyers representing
four (now five) different organizations already,so for the purposes of illustration and explanation only, I have reverse-engineered a new z10-to-Opteron conversion factor as 6.866 z10 EC MIPS per GHz of dual-core AMD Opteron for I/O-intensive workloads running only 10 percent average CPU utilization. Business applications that perform a lot of I/O don't use their CPU as much as other workloads.For compute-intensive or memory-intensive workloads, the conversion factor may be quite different, like 200 MIPS per GHz, as Jeff Savit from Sun Microsystems points out in the comments below.
Keep in mind that each processor is different, and we now have Intel, AMD, SPARC, PA-RISC and POWER (and others); 32-bit versus 64-bit; dual-core and quad-core; and different co-processor chip sets to worry about. AMD Opteron processors come in different speeds, but we are comparing against the 2.8GHz, so 1500 times 6.866 times 2.8 is 28,337. Since these would be running as Linux guestsunder z/VM, we add an additional 7 percent overhead or 2,019 MIPS. We then subtract 15 percent for "smoothing", whichis what happens when you consolidate workloads that have different peaks and valleys in workload, or 4,326 MIPS.The end is that we need a machine to do 26,530 MIPS. Thanks to advances in "Hypervisor" technological synergy between the z/VM operating system and the underlying z10 EC hardware, the mainframe can easily run 90 percent utilized when aggregating multiple workloads, so a 29,477 MIPS machine running at 90 percent utilization can handle these 26,530 MIPS.
N-way machines, from a little 2-way Sun Fire X2100 to the might 64-way z10 EC mainframe, are called "Symmetric Multiprocessors". All of the processors or cores are in play, but sometimes they have to taketurns, wait for exclusive access on a shared resource, such as cache or the bus. When your car is stopped at a red light, you are waiting for your turn to use the shared "intersection". As a result, you don't get linear improvement, but rather you get diminishing returns. This is known generically as the "SMP effect", and in IBM documentsthis as [Large System Performance Reference].While a 1-way z10 EC can handle 920 MIPS, the 64-way can only handle30,657 MIPS. The 29,477 MIPS needed for the Sun x2100 workload can be handled by a 61-way, giving you three extraprocessors to handle unexpected peaks in workload.
But are 1500 Linux guest images architecturally possible? A long time ago, David Boyes of[Sine Nomine Associates] ran 41,400 Linux guest images on a single mainframe using his [Test Plan Charlie], and IBM internallywas able to get 98,000 images, and in both cases these were on machines less powerful than the z10 EC. Neitherof these were tests ran I/O intensive workloads, but extreme limits are always worth testing. The 1500-to-1 reduction in IBM's press release is edge-of-the-envelope as well, so in production environments, several hundred guest images are probably more realistic, and still offer significant TCO savings.
The z10 EC can handle up to 60 LPARs, and each LPAR can run z/VM which acts much like VMware in allowing multipleLinux guests per z/VM instance. For 1500 Linux guests, you could have 25 guests each on 60 z/VM LPARs, or 250 guests on each of six z/VM LPARs, or 750 guests on two LPARs. with z/VM 5.3, each LPAR can support up to 256GB of memory and 32 processors, so you need at least two LPAR to use all 64 engines. Also, there are good reasons to have different guests under different z/VM LPARs, such as separating development/test from production workloads. If you had to re-IPLa specific z/VM LPAR, it could be done without impacting the workloads on other LPARs.
To access storage, IBM offers N-port ID Virtualization (NPIV). Without NPIV, two Linux guest images could not accessthe same LUN through the same FCP port because this would confuse the Host Bus Adapter (HBA), which IBM calls "FICON Express" cards. For example, Linux guest 1 asks to read LUN 587 block 32 and this is sent out a specific port, to a switch, to a disk system. Meanwhile, Linux guest 2 asks to read LUN 587 block 49. The data comes back to the z10 EC with the data, gives it to the correct z/VM LPAR, but then what? How does z/VM know which of the many Linux guests to give the data to? Both touched the same LUN, so it is unclear which made the request. To solve this, NPIV assigns a virtual "World Wide Port Name" (WWPN), up to 256 of them per physical port, so you can have up to 256 Linux guests sharing the same physical HBA port to access the same LUN.If you had 250 guests on each of six z/VM LPARs, and each LPAR had its own set of HBA ports, then all 1500 guestscould access the same LUN.
Yes, the z10 EC machines support Sysplex. The concept is confusing, but "Sysplex" in IBM terminology just means that you can have LPARs either on the same machine or on separate mainframes, all sharing the same time source, whether this be a "Sysplex Timer" or by using the "Server Time Protocol" (STP). The z10 EC can have STP over 6 Gbps Infiniband over distance. If you wantedto have all 1500 Linux guests time stamp data identically, all six z/VM LPARs need access to the shared time source. This can help in a re-do or roll-back situation for Oracle databases to complete or back-out "Units of Work" transactions. This time stamp is also used to form consistency groups in "z/OS Global Mirror", formerly called "XRC" for Extended Remote Distance Copy. Currently, the "timestamp" on I/O applies only to z/OS and Linux and not other operating systems. (The time stamp is done through the CDK driver on Linux, and contributed back to theopen source community so that it is available from both Novell SUSE and Red Hat distributions.)To have XRC have consistency between z/OS and Linux, the Linux guests would need to access native CKD volumes,rather than VM Minidisks or FCP-oriented LUNs.
Note: this is different than "Parallel Sysplex" which refers to having up to 32 z/OS images sharing a common "Coupling Facility" which acts as shared memory for applications. z/VM and Linux do not participate in"Parallel Sysplex".
As for the price, mainframes list for as little as "six figures" to as much as several million dollars, but I have no idea how much this particular model would cost. And, of course, this is just the hardware cost. I could not find the math for the $667 per server replacement you mentioned, so don't have details on that.You would need to purchase z/VM licenses, and possibly support contracts for Linux on System z to be fully comparable to all of the software license and support costs of the VMware, Solaris, Linux and/or Windows licenses you run on the x86 machines.
This is where a lot of the savings come from, as a lot of software is licensed "per processor" or "per core", and so software on 64 mainframe processors can be substantially less expensive than 1500 processors or 3000 cores.IBM does "eat its own cooking" in this case. IBM is consolidating 3900 one-application-each rack-mounted serversonto 30 mainframes, for a ratio of 130-to-1 and getting amazingly reduced TCO. The savings are in the followingareas:
- Hardware infrastructure. It's not just servers, but racks, PDUs, etc. It turns out to be less expensive to incrementally add more CPU and storage to an existing mainframe than to add or replace older rack-em-and-stack-emwith newer models of the same.
- Cables. Virtual servers can talk to each other in the same machine virtually, such as HiperSockets, eliminatingmany cables. NPIV allows many guests to share expensive cables to external devices.
- Networking ports. Both LAN and SAN networking gear can be greatly reduced because fewer ports are needed.
- Administration. We have Universities that can offer a guest image for every student without having a majorimpact to the sys-admins, as the students can do much of their administration remotely, without having physicalaccess to the machinery. Companies uses mainframe to host hundreds of virtual guests find reductions too!
- Connectivity. Consolidating distributed servers in many locations to a mainframe in one location allows youto reduce connections to the outside world. Instead of sixteen OC3 lines for sixteen different data centers, you could have one big OC48 line instead to a single data center.
- Software licenses. Licenses based on servers, cores or CPUs are reduced when you consolidate to the mainframe.
- Floorspace. Generally, floorspace is not in short supply in the USA, but in other areas it can be an issue.
- Power and Cooling. IBM has experienced significant reduction in power consumption and cooling requirementsin its own consolidation efforts.
All of the components of DFSMS (including DFP, DFHSM, DFDSS and DFRMM) were merged into a single product "DFSMS for z/OS" and is now an included element in the base z/OS operating system. As a result of these, customers typically have 80 to 90 percent utilization on their mainframe disk. For the 1500 Linux guests, however, most of the DFSMS features of z/OS do not apply. These functions were not "ported over" to z/VM nor Linux on any platform.
Note: DFSMS can backup or dump Linux on System z partitions or volumes. See this [Appendix C. HOWTO backup Linux data through z/OS] for details.
Instead, the DFSMS concepts have been re-implemented into a new product called "Scale-Out File Services" (SOFS) which would provide NAS interfaces to a blendeddisk-and-tape environment. The SOFS disk can be kept at 90 percent utilization because policies can place data, movedata and even expire files, just like DFSMS does for z/OS data sets. SOFS supports standard NAS protocols such as CIFS,NFS, FTP and HTTP, and these could be access from the 1500 Linux guests over an Ethernet Network Interface Card (NIC), which IBM calls "OSA Express" cards.
Lastly, IBM z10 EC is not emulating x86 or x86-64 interfaces for any of these workloads. No doubt IBM and AMD could collaborate together to come up with an AMD Opteron emulator for the S/390 chipset, and load Windows 2003 right on top of it, but that would just result in all kinds of emulation overhead.Instead, Linux on System z guests can run comparable workloads. There are many Linux applications that are functionally equivalent or the same as their Windows counterparts. If you run Oracle on Windows, you could runOracle on Linux. If you run MS Exchange on Windows, you could run Bynari on Linux and let all of your Outlook Expressusers not even know their Exchange server had been moved! Linux guest images can be application servers, web servers, database servers, network infrastructure servers, file servers, firewall, DNS, and so on. For nearly any business workload you can assign to an x86 server in a datacenter, there is likely an option for Linux on System z.
Hope this answers all of your questions, Jon. These were estimates based on basic assumptions. This is not to imply that IBM z10 EC and VMware are the only technologies that help in this area, you can certainly find virtualization on other systems and through other software.I have asked IBM to make public the "TCO framework" that sheds more light on this.As they say, "Your mileage may vary."
For more on this series, check out the following posts:
If in your travels, Jon, you run into someone interested to see how IBM could help consolidate rack-mounted servers over to a z10 EC mainframe, have them ask IBM for a "Scorpion study". That is the name of the assessment that evaluates a specific clientsituation, and can then recommend a more accurate estimate configuration.

Last year, I started my post[Hu Yoshida should know better
I am still wiping the coffee off my computer screen, inadvertently sprayed when I took a sip while reading HDS' uber-blogger Hu Yoshida's post on storage virtualization and vendor lock-in.
HDS is a major vendor for disk storage virtualization, and Hu Yoshida has been around for a while, so I felt it was fair to disagree with some of the generalizations he made to set the record straight. He's been more careful ever since.
However, his latest post [The Greening of IT: Oxymoron or Journey to a New Reality] mentions an expert panel at SNW that includedMark O’Gara Vice President of Infrastructure Management at Highmark. I was not at the SNW conference last week in Orlando, so I will just give the excerpt from Hu's account of what happened:
"Later I had the opportunity to have lunch with Mark O’Gara. Mark is a West Point graduate so he takes a very disciplined approach to addressing the greening of IT. He emphasized the need for measurements and setting targets. When he started out he did an analysis of power consumption based on vendor specifications and came up with a number of 513 KW for his data center infrastructure....
The physical measurements showed that the biggest consumers of power were in order: Business Intelligence Servers, SAN Storage, Robotic tape Library, and Virtual tape servers....
Another surprise may be that tape libraries are such large consumers of power. Since tape is not spinning most of the time they should consume much less power than spinning disk - right? Apparently not if they are sitting in a robotic tape library with a lot of mechanical moving parts and tape drives that have to accelerate and decelerate at tremendous speeds. A Virtual Tape Library with de-duplication factor of 25:1 and large capacity disks may draw significantly less power than a robotic tape library for a given amount of capacity.
Obviously, I know better than to sip coffee whenever reading Hu's blog. I am down here in South America this week, the coffee is very hot and very delicious, so I am glad I didn't waste any on my laptop screen this time, especially reading that last sentence!
Last month, in my post [Disk only customers going back to tape], I mentioned some statistics from the Clipper Group's whitepaper[Disk and Tape Square Off Again —Tape Remains King of the Hill with LTO-4] by analysts David Reine and Mike Kahn.
In that report, a 5-year comparison found that a repository based on SATA disk was 23 times more expensive overall, and consumed 290 times more energy, than a tape library based on LTO-4 tape technology. The analysts even considered a disk-based Virtual Tape Library (VTL). Focusing just on backups, at a 20:1 deduplication ratio, the VTL solution was still 5 times per expensive than the tape library. If you use the 25:1 ratio that Hu Yoshida mentions in his post above, that would still be 4 times more than a tape library.
I am not disputing Mark O'Gara's disciplined approach.
It is possible that Highmark is using a poorly written backup program, taking full backups every day, to an older non-IBM tape library, in a manner that causes no end of activity to the poor tape robotics inside. But rather than changing over to a VTL, perhaps Mark might be better off investigating the use of IBM Tivoli Storage Manager, using progressive backup techniques, appropriate policies, parameters and settings, to a more energy-efficient IBM tape library.In well tuned backup workloads, the robotics are not very busy. The robot mounts the tape, and then the backup runs for a long time filling up that tape, all the meanwhile the robot is idle waiting for another request.
(Update: My apologies to Mark and his colleagues at Highmark. The above paragraph implied that Mark was using badproducts or configured them incorrectly, and was inappropriate. Mark, my full apology [here])
If you do decide to go with a Virtual Tape Library, for reasons other than energy consumption, doesn't it make sense to buy it from a vendor that understands tape systems, rather than buying it from one that focuses on disk systems? Tape system vendors like IBM, HP or Sun understand tape workloads as well as related backup and archive software, and can provide better guidance and recommendations based on years of experience. Asking advice abouttape systems, including Virtual Tape Libraries, from a disk vendor is like asking for advice on different types of bread from your butcher, or advice about various cuts of meat at the bakery.
The butchers and bakers might give you answers, but it may not be the best advice.

Last week, I presented IBM's strategic initiative, the IBM Information Infrastructure, which is part of IBM's New Enterprise Data Center vision. This week, I will try to get around to talking about some of theproducts that support those solutions.
There has been a lot of attention on XIV in the past few weeks, so I will start with that. Steve Duplessie, anIT industry analyst from Enterprise Strategy Group (ESG) had a post [Adaptec buys Aristos, Tom Cruise, XIV, and Logical Assumptions] with some interesting observations and some sage advice.Val Bercovici on his NetApp Exposed blog, has a post [Has Storage Swift-Blogging Finally Jumped the Shark?] which blasts EMC for their negativity.
(For those not in the USA, swift-blogging is a reference tofalse accusations and negative remarks made during the U.S. 2004 presidential election by the[Swift Boat Veterans], and ["jumping the shark"] is a reference to [a TV show that ran out of interesting and relevant topics].For movie sequels, the comparable phrase is ["nuke the fridge"] in reference to the most recent Indiana Jones' movie.)
I was going to set the record straight on a variety of misunderstandings, rumors or speculations, but I think most have been taken care of already. IBM blogger BarryW covered the fact that SVC now supports XIV storage systems, in his post[SVC and XIV],and addressed some of the FUD already. Here was my list:
- Now that IBM has an IBM-branded model of XIV, IBM will discontinue (insert another product here)
I had seen speculation that XIV meant the demise of the N series, the DS8000 or IBM's partnership with LSI.However, the launch reminded people that IBM announced a new release of DS8000 features, new models of N series N6000,and the new DS5000 disk, so that squashes those rumors.
- IBM XIV is a (insert tier level here) product
While there seems to be no industry-standard or agreement for what a tier-1, tier-2 or tier-3 disk system is, there seemed to be a lot of argument over what pigeon-hole category to put IBM XIV in. No question many people want tier-1 performance and functionality at tier-2 prices, and perhaps IBM XIV is a good step at giving them this. In some circles, tier-1 means support for System z mainframes. The XIV does not have traditional z/OS CKD volume support, but Linux on System z partitions or guests can attach to XIV via SAN Volume Controller (SVC), or through NFS protocol as part of the Scale-Out File Services (SoFS) implementation.
Whenever any radicalgame-changing technology comes along, competitors with last century's products and architectures want to frame the discussion that it is just yet another storage system. IBM plans to update its Disk Magic and otherplanning/modeling tools to help people determine which workloads would be a good fit with XIV.
- IBM XIV lacks (insert missing feature here) in the current release
I am glad to see that the accusations that XIV had unprotected, unmirrored cache were retracted. XIV mirrors all writes in the cache of two separate modules, with ECC protection. XIV allows concurrent code loadfor bug fixes to the software. XIV offers many of the features that people enjoy in other disksystems, such as thin provisioning, writeable snapshots, remote disk mirroring, and so on.IBM XIV can be part of a bigger solution, either through SVC, SoFS or GMAS that provide thebusiness value customers are looking for.
- IBM XIV uses (insert block mirroring here) and is not as efficient for capacity utilization
It is interesting that this came from a competitor that still recommends RAID-1 or RAID-10 for itsCLARiiON and DMX products.On the IBM XIV, each 1MB chunk is written on two different disks in different modules. When disks wereexpensive, how much usable space for a given set of HDD was worthy of argument. Today, we sell you abig black box, with 79TB usable, for (insert dollar figure here). For those who feel 79TB istoo big to swallow all at once, IBM offers "capacity on demand" pricing, where you can pay initially for as littleas 22TB, but get all the performance, usability, functionality and advanced availability of the full box.
- IBM XIV consumes (insert number of Watts here) of energy
For every disk system, a portion of the energy is consumed by the number of hard disk drives (HDD) andthe remainder to UPS, power conversion, processors and cache memory consumption. Again, the XIV is a bigblack box, and you can compare the 8.4 KW of this high-performance, low-cost storage one-frame system with thewattage consumed by competitive two-frame (sometimes called two-bay) systems, if you are willing to take some trade-offs. To getcomparable performance and hot-spot avoidance, competitors may need to over-provision or use faster, energy-consuming FC drives, and offer additional software to monitor and re-balance workloads across RAID ranks.To get comparable availability, competitors may need to drop from RAID-5 down to either RAID-1 or RAID-6.To get comparable usability, competitors may need more storage infrastructure management software to hide theinherent complexity of their multi-RAID design.
Of course, if energy consumption is a major concern for you, XIV can be part of IBM's many blended disk-and-tapesolutions. When it comes to being green, you can't get any greener storage than tape! Blended disk-and-tapesolutions help get the best of both worlds.
Well, I am glad I could help set the record straight. Let me know what other products people you would like me to focus on next.

This is not the first time I've been published. I have authored articles for storage industry magazines, written large sections of IBM publications and manuals, submitted presentations and whitepapers to conference proceedings, and even had a short story published with illustrations by the famous cartoon writer[Ted Rall].
But I can say this is my first blook, and as far as I can tell, the first blook from IBM's many bloggers on DeveloperWorks, and the first blook about the IT storage industry.I got the idea when I saw [Lulu Publishing] run a "blook" contest. The Lulu Blooker Prize is the world's first literary prize devoted to "blooks"--books based on blogs or other websites, including webcomics. The [Lulu Blooker Blog] lists past year winners. Lulu is one of the new innovative "print-on-demand" publishers. Rather than printing hundredsor thousands of books in advance, as other publishers require, Lulu doesn't print them until you order them.
I considered cute titles like A Year of Living Dangerously, orAn Engineer in Marketing La-La land, or Around the World in 165 Posts, but settled on a title that matched closely the name of the blog.
In addition to my blog posts, I provide additional insights and behind-the-scenes commentary. If you go to the Luluwebsite above, you can preview an entire chapter in its entirety before purchase. I have added a hefty 56-page Glossary of Acronyms and Terms (GOAT) with over 900 storage-related terms defined, which also doubles as an index back to the post (or posts) that use or further explain each term.
So who might be interested in this blook?
- Business Partners and Sales Reps looking to give a nice gift to their best clients and colleagues
- Managers looking to reward early-tenure employees and retain the best talent
- IT specialists and technicians wanting a marketing perspective of the storage industry
- Mentors interested in providing motivation and encouragement to their proteges
- Educators looking to provide books for their classroom or library collection
- Authors looking to write a blook themselves, to see how to format and structure a finished product
- Marketing personnel that want to better understand Web 2.0, Second Life and social networking
- Analysts and journalists looking to understand how storage impacts the IT industry, and society overall
- College graduates and others interested in a career as a storage administrator
And yes, according to Lulu, if you order soon, you can have it by December 25.

IBM once again delivers storage innovation!
(Note: The following paragraphs have been updated to clarify the performance tests involved.)
This time, IBM breaks the 1 million IOPS barrier, achieved by running a test workload consisting of a 70/30 mix of random 4K requests. That is 70 percent reads, 30 percent writes, with 4KB blocks. The throughput achieved was 3.5x times that obtained by running the identical workload on the fastest IBM storage system today (IBM System Storage SAN Volume Controller 4.3),
and an estimated EIGHT* times the performance of EMC DMX. With an average response time under 1 millisecond, this solution would be ideal for online transaction processing (OLTP) such as financial recordings or airline reservations.
(*)Note: EMC has not yet published ANY benchmarks of their EMC DMX box with SSD enterprise flash drives (EFD). However, I believe that the performance bottleneck is in their controller and not the back-end SSD or FC HDD media, so I have givenEMC the benefit of the doubt and estimated that their latest EMC DMX4 is as fast as an[IBMDS8300 Turbo] with Fibre Channel drives. If or when EMC publishes benchmarks, the marketplace can make more accurate comparisons. Your mileage may vary.
IBM used 4 TB of Solid State Disk (SSD) behind its IBM SAN Volume Controller (SVC) technology to achieve this amazing result. Not only does this represent a significantly smaller footprint, but it uses only 55 percent of the power and cooling.
The SSD drives are made by [Fusion IO] and are different than those used by EMC made by STEC.
The SVC addresses the one key problem clients face today with competitive disk systems that support SSD enterprise flash drives: choosing what data to park on those expensive drives? How do you decide which LUNs, which databases, or which files should be permanently resident on SSD? With SVC's industry-leading storage virtualization capability, you are not forced to decide. You can move data into SSD and back out again non-disruptively, as needed to meet performance requirements. This could be handy for quarter-end or year-end processing, for example.
For more on this, see the [IBM Press Release] or thearticles in [Network World] by Jon Brodkin, and [Cnet News] by Brooke Crothers.
Our clients have often told us at IBM that performance is one of their top purchase criteria. IBM once again has shown that it listens to the marketplace!

Continuing my week in Chicago for the IBM Storage and Storage Networking Symposium and System x and BladeCenter Technical Conference, I presented a variety of topics.
- Hybrid Storage for a Green Data Center
The cost of power and cooling has risen to be a #1 concern among data centers. I presented the following hybrid storage solutions that combine disk with tape. These provide the best of both worlds, the high performance access time of disk with the lower costs and reduced energy consumption of tape.
- IBM [System Storage DR550] - IBM's Non-erasable, Non-rewriteable (NENR) storage for archive and compliance data retention
- IBM Grid Medical Archive Solution [GMAS] - IBM's multi-site grid storage for PACS applications and electronic medical records[EMR]
- IBM Scale-out File Services [SoFS] - IBM's scalable NAS solution that combines a global name space with a clustered GPFS file system, serving as the ideal basis for IBM's own[Cloud Computing and Storage] offerings
Not only do these help reduce energy costs, they provide an overall lower total cost of ownership (TCO) thantraditional WORM optical or disk-only storage configurations.
- The Convergence of Networks - Understanding SAN, NAS and iSCSI in the Data Center Network
This turned out to be my most popular session. Many companies are at a crossroads in choosing data and storage networking solutions in light of recent announcements from IBM and others. In the span of 75 minutes, I covered:
- Block storage concepts, storage virtualization and RAID levels
- File system concepts, how file systems map files to block storage
- Network Attach Storage, the history of the NFS and CIFS protocols, Pros and Cons of using NAS
- Storage Area Networks, the history of SAN protocols including ESCON, FICON and FCP, Pros and Cons of using SAN
- IP SAN technologies, iSCSI and Fibre Channel over Ethernet (FCoE), Pros and Cons of using this approach
- Network Convergence with Infiniband and Fibre Channel over Convergence Enhanced Ethernet (FCoCEE), why Infiniband was not adopted historically in the marketplace as a storage protocol, and the features and enhancements of Convergence Enhanced Ethernet (CEE) needed to merge NAS, SAN and iSCSI traffic onto a single converged data center network [DCN]
Yes, it was a lot of information to cover, but I managed to get it done on time.
- IBM Tivoli Storage Productivity Center version 4.1 Overview and Update
In conferences like these, there are two types of product-level presentations. An "Overview" explains howproducts work today to those who are not familiar with it. An "Update" explains what's new in this version of the product for those who are already familiar with previous releases. I decided to combine these into one sessionfor IBM's new version of [Tivoli Storage Productivity Center].I was one of the original lead architects of this product many years ago, and was able to share many personalexperiences about its evolution in development and in the field at client facilities.Analysts have repeatedly rated IBM Productivity Center as one of the top Storage Resource Management (SRM) tools available in the marketplace.
- Information Lifecycle Management (ILM) Overview
Can you believe I have been doing ILM since 1986? I was the lead architect for DFSMS which provides ILM support for z/OS mainframes. In 2003-2005, I spent 18 months in the field performingILM assessments for clients, and now there are dozens of IBM practitioners in Global Technology Services andSTG Lab Services that do this full time. This is a topic I cover frequently at the IBM Executive Briefing Center[EBC], because it addressesseveral top business challenges:
- Reducing costs and simplifying management
- Improving efficiency of personnel and application workloads
- Managing risks and regulatory compliance
IBM has a solution based on five "entry points". The advantage of this approach is that it allows our consultants to craft the right solution to meet the specific requirements of each client situation. These entry points are:
- Enterprise Content Management [ECM]
- Tiered Information Infrastructure - we don't limit ourselves to just "Tiered Storage" as storage is only part of a complete[information infrastructure] of servers,networks and storage
- Storage Optimization and Virtualization - including virtual disk, virtual tape and virtual file solutions
- Process Enhancement and Automation - an important part of ILM are the policies and procedures, such as IT Infrastructure Library [ITIL] best practices
- Archive and Retention - space management and data retention solutions for email, database and file systems
I did not get as many attendees as I had hoped for this last one, as I was competing head-to-head in the same time slot as Lee La Frese covering IBM's DS8000 performance with Solid State Disk (SSD) drives, John Sing covering Cloud Computing and Storage with SoFS, and Eric Kern covering IBM Cloudburst.
I am glad that I was able to make all of my presentations at the beginning of the week, so that I can then sit back and enjoy the rest of the sessions as a pure attendee.

This week, I am in Costa Rica to blog about "Earth Day" which officially is this Wednesday, April 22.
Fellow published author Thomas Friedman has a book titled[Hot, Flat, and Crowded: Why We Need a Green Revolution - and How It Can Renew America] which serves as a call to action for Americans. His recent op-ed piece in the New York Times newspaper, titled [(No) Drill, Baby, Drill] is all about Costa Rica. Here is an excerpt:
"These days, visitors can still see amazing biodiversity all over Costa Rica — more than 25 percent of the country is protected area — thanks to a unique system it set up to preserve its cornucopia of plants and animals. Many countries could learn a lot from this system.
More than any nation I’ve ever visited, Costa Rica is insisting that economic growth and environmentalism work together. It has created a holistic strategy to think about growth, one that demands that everything gets counted. So if a chemical factory sells tons of fertilizer but pollutes a river — or a farm sells bananas but destroys a carbon-absorbing and species-preserving forest — this is not honest growth. You have to pay for using nature. It is called “payment for environmental services” — nobody gets to treat climate, water, coral, fish and forests as free anymore.
The process began in the 1990s when Costa Rica, which sits at the intersection of two continents and two oceans, came to fully appreciate its incredible bounty of biodiversity — and that its economic future lay in protecting it. So it did something no country has ever done: It put energy, environment, mines and water all under one minister.
“In Costa Rica, the minister of environment sets the policy for energy, mines, water and natural resources,” explained Carlos M. Rodríguez, who served in that post from 2002 to 2006. In most countries, he noted, “ministers of environment are marginalized.” They are viewed as people who try to lock things away, not as people who create value. Their job is to fight energy ministers who just want to drill for cheap oil.
But when Costa Rica put one minister in charge of energy and environment, “it created a very different way of thinking about how to solve problems,” said Rodríguez, now a regional vice president for Conservation International. “The environment sector was able to influence the energy choices by saying: ‘Look, if you want cheap energy, the cheapest energy in the long-run is renewable energy. So let’s not think just about the next six months; let’s think out 25 years.’ ”
As a result, Costa Rica hugely invested in hydro-electric power, wind and geo-thermal, and today it gets more than 95 percent of its energy from these renewables. In 1985, it was 50 percent hydro, 50 percent oil. More interesting, Costa Rica discovered its own oil five years ago but decided to ban drilling — so as not to pollute its politics or environment! What country bans oil drilling?
Rodríguez also helped to pioneer the idea that in a country like Costa Rica, dependent on tourism and agriculture, the services provided by ecosystems were important drivers of growth and had to be paid for. Right now, most countries fail to account for the “externalities” of various economic activities. So when a factory, farmer or power plant pollutes the air or the river, destroys a wetland, depletes a fish stock or silts a river — making the water no longer usable — that cost is never added to your electric bill or to the price of your shoes.
Costa Rica took the view that landowners who keep their forests intact and their rivers clean should be paid, because the forests maintained the watersheds and kept the rivers free of silt — and that benefited dam owners, fishermen, farmers and eco-tour companies downstream. The forests also absorbed carbon."
|I start my visit at Arenal, where there is a hydro-electric dam at Lake Arenal that produces electricity, a large volcano, and natural hot springs.I found [more stats on Costa Rica's energy consumption] that provide more details.|
At left is a photo I took of the Volcano Arenal. This is just one of the 112 volcanoes in thecountry.
At the [Springs Resort and Spa], they have clear (chlorinated) swimming pools maintained at three different temperatures. I asked our guide,Alan, if the pools were being heated from the electricity generated from the dam at the lake.No, they use green water for green energy. Taking advantage of "geo-thermal" energy, the natural hot springs are run through a [Heat Exchanger], to heat the pools. The waters do not mix, keeping the clean water clean. The process is similar to IBM's [Rear Door Heat eXchanger].
|Why don't people just soak directly in the green water directly? Alan responded, "You can certainly enjoy soaking in the green water, but I recommend you buy some storage, which will cost you extra, as a souvenir."|
The storage, shown here at right, holds cash and credit cards with a water-tight seal. Normal pool water won'teffect cash or credit cards, and I have certainly seen people pay for food and drinks with soggy dollars in other places. This water is literally green, and perhaps not for everyone. How green is it? Think watered-down version of [split-pea soup] and you will have a close approximation.I thoroughly enjoyed the experience, but am going to need some industrial-strength scum-and-lime remover to clean the glass face of my waterproof watch when I get back home.
Fortunately, I speak the Castellano dialect of Spanish that is spoken here in Costa Rica,and this will allow me to continue to gather more information about how Costa Rica leads the way in being more energy efficient and environmentally responsible.

Well, it's Tuesday, and so it is "announcement day" again! Actually, for me it is Wednesday morning herein Mumbai, India, but since I was "press embargoed" until 4pm EDT in talking about these enhancements, I had to wait until Wednesday morning here to talk about them.
- World's Fastest 1TB tape drive
|IBM announced its new enterprise [TS1130 tape drive]and corresponding [TS3500 tape library support]. This one has a funny back-story. Last week while we were preparing the Press Release, we debated on whether we should compare the 1TB per cartridge capacity as double that of Sun's Enterprise T10000 (500GB), or LTO-4 (800GB). The problem changed when Sun announced on Monday they too had a 1TB tape drive, so now instead ofsaying that we had the "World's First 1TB tape drive", we quickly changed this to the "World's Fastest 1TB tape drive" instead. At 160MB/sec top speed, IBM's TS1130 is 33 percent faster than Sun's latest announcement. Sun was rather vague when they will actually ship their new units, so IBM may still end up being first to deliver as well.|
Here is an IBM podcast to hear more about it:
While EMC and other disk-only vendors have stopped claiming that "tape is dead", these recent announcements from IBM and Sun indicate that indeed tape is alive and well. IBM is able to borrow technologies from disk, such as the Giant Magneto Resistive (GMR) head over to its tape offerings, which means much of the R&D for disk applies to tape, keeping both forms ofstorage well invested. Tape continues to be the "greenest" storage option, more energy efficient than disk, optical, film, microfiche and even paper.
- Improved Reporting
On the LTO front, IBM enhanced the reporting capabilities of its[TS3310] midrange tape library. This includes identifying the resource utilization of the drives, reporting on media integrity, and improved diagnostics to support library-managed encryption.
- IBM System Storage DR550
As a blended disk-and-tape solution, the [IBM System Storage DR550] easily replaces the EMC Centera to meet compliance storagerequirements. IBM announced that we have greatly expanded its scalability, being able to support both 1TBdisk drives, as well as being able to attach to either IBM or Sun's 1TB tape drives.
- Massive Array of Idle Disks (MAID)
IBM now offers a "Sleep Mode" in the firmware of the [IBM System Storage DCS9550], which is often called "Massive Array of Idle Disks" (MAID) or spin-down capability. This can reduce the amount of power consumed during idle times.
That's a lot of exciting stuff. I'm off to breakfast now.

Well, it's Tuesday, so that means IBM announcements!
We had so much announced, that I will just cover the disk systems today, and deal with tape systems and software tomorrow.
- IBM System Storage DS8000 series
IBM continues to invest heavily in its strategic [DS8000 series].For [existing 2107 machines], IBM's new DS8000 microcode supports:
- 1 TB 7200 rpm Serial ATA (SATA) Disk Drives
Now that IBM XIV has proven that 1TB SATA are safe for high-end tier-1 enterprise class use, we extended DS8000 support to include SATA support also. DS8000 supports RAID-6 and RAID-10 for these.
- Intelligent Write Caching
IBM Research conducts extensive investigations into improved algorithms for cache management. Intelligent Write Caching boosts performance for both temporal and spatial locality.
- Remote Pair FlashCopy®
This allows you to FlashCopy volume A to volume B, with Volume B remotely mirrored to Volume C at a secondary location, via Metro Mirror. This allows you to have a consistent copy of your data at both locations.
For[newly ordered 242x models], you get all the features above, plus the following additional support:
- Full Disk Encryption (FDE)
IBM was the first in the industry to deliver tape-drive encryption, so it makes sense that IBM is also the first in the industry to deliver disk-drive encryption. These are 15K rpm drives in standard 146GB, 300GB and 450GB capacities. As with tape, encrypting at the disk device eliminates the huge overhead from server-based encryption methods.
- Solid State Drive (SSD)
You can also have Solid State Disk drives in your DS8000, in 73GB and 146GB capacities, protected by RAID-5.If you are wondering what data to put on these much-faster drives, IBM has taken the work and worry out by havingintelligence in DB2 to optimize what gets placed on SSD to get the most performance improvement.
- IBM System Storage XIV
Continuing the incredible marketplace excitement over its Cloud-Opimized Storage[XIV series], IBM now has announced[new capacity options]. The IBM XIV R2 that we announced last August 2008 was a fixed 15 module configuration. In thenew configurations, you can start with as little as six modules, representing a 40% partial rack of the originalfull model. Here is a table that shows the details:
|Total Modules|| 6 || 9 || 10 || 11 || 12 || 13 ||14 || 15|
| Useable Capacity (TB) ||27 || 43 || 50 || 54 || 61 || 66 || 73 || 79|
|Interface Modules ||3 || 6 || 6 || 6 || 6 || 6 || 6 || 6|
|Data Modules ||3 || 3 || 4 || 5 || 6 || 7 || 8 || 9|
|Disk Drives ||72 || 108 || 120 || 132 || 144 || 156 || 168 || 180|
|Fibre Channel Ports ||8 || 16 || 16 || 20 || 20 || 24 || 24 || 24|
|iSCSI Ports ||0 || 4 || 4 || 6 || 6 || 6 || 6 || 6|
|Cache Memory (GB) ||48 || 72 || 80 || 88 || 96 || 104 || 112 || 120|
- IBM System Storage N series
And last, but not least, we have two new models in IBM's[N6000 series].The [N6060]has model A12 (single controller) and model A22 (dual controller). These are disk-less controllers thatyou can configure in either appliance mode or gateway mode. In appliance mode, you can attachdisk drawers such as the EXN1000, EXN2000 or EXN4000. In gateway mode, you attach external disk systems, suchas the IBM DS8000 or XIV above.
Also, IBM introduces the new [2101 model N42 rack], which has the following features:
- It's ruggedized to handle earthquakes. IBM brings a feature that we've had for a while on other disk systems to the N series with a collection of bolts and anchors to secure the rack from physical tremors.
- It's instrumented for IBM Active Energy Manager, a component of IBM Systems Director. New iPDUs are designed to help measure and monitor energy management components. As companies get more concerned about thefate of the planet, monitoring energy consumption can help reduce carbon footprint.
I'll cover the rest of the announcements tomorrow!

Chuck Hollis makes some excellent points about Green Data Center Goes Marketing Mainstream
. He does a great job summarizing EMC's strategy in this area:
- Use VMware to virtualize your x86-based servers
- Use more efficient disk media, such as high-capacity SATA disk drives
Both are great recommendations, but why limit yourself to what EMC offers? Your x86-based machines are only a subset of your servers,and disk is only a subset of your storage. IBM takes a more holistic approach, looking at the entire data center.
- VMware is a great product, and IBM is its top reseller. But in addition to VMware, there are other solutions for the x86-based servers, like Xen and Microsoft Virtual Server. IBM's System p, System i, and System z product lines all support logical partitioning.
To compare the energy effectiveness of server virtualization, consider a metric that can apply across platforms. For example, for an e-mail server, consider watts per mailbox. If you have, say, 15,000 users, you can calculate how many watts you are consuming to manage their mailboxes on your current environment, and compare that with running them on VMware, or logical partitions on other servers. Some people find it surprising that it is often more cost-effective, and power-efficient, to run workloads on mainframe logical partitions (LPARs) than a stack of x86 servers running VMware.
- More efficient Media
- SATA and FATA disks support higher capacities, and run at slower RPM speeds, thus using fewer watts per terabyte.A terabyte stored on 73GB high-speed 15K RPM drives consumes more watts than the same terabyte stored using 500GB SATA.Chuck correctly identifies that tape is more power-efficient than disk, but then argues that paper is more power-efficient than tape. But paper is not necessarily more efficient than tape.
ESG analyst Steve Duplessie divides up data betweenDynamic vs. Persistent. The best place to put dynamic data is on disk, and here is where evaluation of FC/SAS versus SATA/FATA comes into play.Persistent data, on the other hand, can be stored on paper, microfiche, optical or tape media. All of these shelf-resident media consume no electricity, nor generate any heat that would require additional cooling.
A study by scientists at the Lawrence Berkeley National Laboratory titled High-Tech Means High-Efficiency: The Business Case for Energy Management in High-Tech Industries indicates thatData centers consume 15 to 100 times more energy per square foot than traditional office space. Storing persistent data in traditional office space can save a huge amount of energy. Steve Duplessie feels the ratio of dynamic to persistent data is 1:10 today, but is likely to grow to 1:100 in the near future, raising the demand for energy-efficient storage of persistent data ever more important to our environment.
Data centers consume nearly 5000 Megawatts in the USA alone, 14000 Megawatts worldwide. To put that in perspective, the country of Hungary I was in last week can generate up to 8000 Megawatts for the entire country (and they were using 7400 Megawatts last week as a result of their current heat wave, causing them grave concern).
Back in the 1990's, one of the insurance companies IBM worked with kept data on paper in manila folders, and armiesof young adults in roller skates were dispatched throughout the large warehouses of shelves to get the appropriate folder in response to customer service inquiries. Digitizing this paper into electronic format greatly reduced the need for this amount of warehouse space, as well as improved the time to retrieve the data.
A typical file storage box (12 inch x 12 inch x 18 inch) containing typed pages single-spaced, double-sided, 12 point font could hold perhaps 100MB. The same box could hold a hundred or more LTO or 3592 tape cartridges, each storing hundreds of GB of information. That's a million-to-one improvement of space-efficiency, and from a watts-per-TB basis, translates to substantial improvement in standard office air conditioning and lighting conditions.

Continuing this week's theme on Earth Day, I am in San José, the capital of Costa Rica.
|Despite all the talk I heard about how great Costa Rica was, ranked 5th in the world as one of thegreenest countries, I had a hard time breathing the air in San José.Here's a picture I took from my hotel in Escazú, which overlooks the city. |
I have been to the [Top 5 smogiest cities in the world] --Mexico City, Sao Paulo, Cairo, New Dehli, and Shanghai-- and can say that San Jose,Costa Rica is nowhere near as bad as any of those, and more on par with cities in the United States, like Pittsburgh or Los Angeles.
Having a single government official in charge of both energy and environment means they can set pricesand provide incentives in one to benefit the other. Here are two examples:
Only 5 percent of the energy consumption of this county comes from oil. Despite having their own oilrepositories off-shore, the Costa Ricans have decided not to drill and ruin their pristine shoreline,but rather import from foreign sources.Gasoline prices are set high to include some of the environmental costs, about four dollars per gallon(800 Costa Rican Colones per liter). Cars can be converted to run on less expensive Propane orsugar cane Ethanol, but the conversions are cost-prohibitive for many.
Did it help? No, Traffic was like a parking lot. Part of this was the result of the main highway beingunder construction, forcing many people to take side streets.
Electricity is 13 US cents per KWh. My hotel in Escazu wanted an extra $8.50 US dollars per day to run theAir Conditioner. By comparison, my house in Tucson, Arizona is 1167 square feet, roughly five to six times the size of my hotel room, and my electricity bill is a flat 27 US dollars per month year round.
Did it help? No, most tourists just pay the extra cost. I tried one day with A/C, and the second day without, for scientific comparison, and decided to go without the rest of the time I was there. Perhaps being from Tucson, Arizona I can tolerate the 85-degree heat better than others.
So if incentives to conserve like high prices don't work, what will? I interviewed Alexandra,a local 24-year-old studying law at a nearby college:
- Once you get your law degree, will you move to another country, such as the United States? --There are already too many lawyers in your country.
- What about Japan or Asia, there is a shortage of lawyers there?-- No, I plan to stay here in my country. Costa Rica is beautiful, my friends and family are here, why would I leave?
- So why do you think the incentives don't work to help people conserve gasoline and electricity? --People have to earn a living, and are focused on getting things done. If it can be done in a way that helps the environment, great, but otherwise life continues.
- So will you specialize in "environmental" law? -- Not sure yet. Too early to say. Costa Rica is certainly leading the world in environmental protection, and much of this is through laws and tax schemes.
High prices don't serve well as incentives to reduce consumption, but perhaps national pride and working in an industry like agriculture or eco-tourism might.

It's that time again. Every year, IBM hosts the "System Storage Technical University". I have been going to these since they first started in the 1990s. This time we are at the lovely [Hilton Orlando] in Orlando, Florida.
For those who want to relive past events, here are my blog posts from this event in 2010:
The list of sessions that I will be presenting this week were detailed last month in my post [Don't Miss IBM Storage Technical University 2011].
As was the case last year, IBM once again will run this conference alongside the [IBM System x Technical University] the same week, in the same hotel. This allows attendees to cross over to the other side to see a few sessions of the other conference. I took advantage of this last year, and plan to do so again this year as well!

Well, we had another successful event in Second Life today.
Unlike our April 26 launch of our System Storage products for IBM Business Partners only, this time we decided this time to make it as a "Meet the Storage Experts" Q&A Panel format, and open up registration to everyone. Thesubject matter experts sat at the front of the room on four stools. We had six rows of chairs arrangedsemi-circularly.
Shown above, from left to right, are the avatars of our four experts:
- Steve Grillo
- IBM System Storage N series, focusing on recent N3000 disk system announcements
- Harold Pike (holding the microphone while speaking)
- IBM System Storage DS3000 and DS4000 series, focusing on recent DS3000 disk system announcements
- Eric Buckley
- IBM System Storage TS series, focusing on recent TS2230, TS3400 and TS7700 tape system announcements
- Pete Danforth
- IBM storage networking, focusing on recent IBM SAN256B director blade announcements
(you can read more about these products here:July announcements
While Eric was a veteran Second Lifer, having presented at our April event, the other three were trainedon how to raise their hand, speak into the microphone, sit on the stool, and so on. I want to thank allof our experts for putting in this effort!
The event was produced by Katrina H Smith. She did a great job, and made sure we were on top ofall the issues and tasks required to get the job done. Running a Second Life event is every bit ashard as running a real face-to-face event. We had several meetings to discuss venue details, placementof chairs, placement of product demos, audio/video recording, wall decorations, tee-shirt and coffee mug design, logistics, and so on.
I acted as moderator/emcee for the event. That is my back in the picture above. The process wassimple, modeled after the "Birds of a Feather" sessions at events like SHARE and the IBMStorage and Storage Networking Symposium. We threw out a list of topics the experts would cover,and people in the audience would "raise their left hand". I, as the moderator, would then walkover to each person, and hold out the microphone for them to ask the question. I would then repeat the question and ask the appropriate expert to provide an answer. We defined gestures onhow to "raise hand" and "put hand down" that we gave to each registered participant.
We had four dedicated "camera-avatars" in world to capture both video and screenshots.Our video editors are now working to edit "highlight videos" that we can use at future events, for training materials, and for our internal "BlueTube" online video system.
The room was filled with examples of each of our products, made into 3D objects that were dimensionallycorrect, and "textured" with photographs of the actual products. If you click on an object, you get a "notecard" that provided more information. Special thanks to Scott Bissmeyer for making all of theseobjects for us.
We made posters of each expert and placed them in all four corners of the room. On the bottom of each coffee mug was a picture of each of the experts, and if you walked under each of the posters, you were"dispensed" a coffee mug matching the expert shown in the poster.Participants could "Collect all Four!" When you bring the coffee mug up to takea sip, the picture on the bottom of the mug is exposed for all to see.And as a final give-away to the audience, we made a variety of event tee-shirts and polo-shirts.
At the end of the session, we asked everyone to click on the "Survey" kiosk near the exit door. We askedsix simple questions using SurveyMonkey.com that took only a fewminutes to process. We found asking questions immediately at the end of the event was the best way tocapture this feedback.
From a "Green" perspective, we had people registered from the following countries: US, India, Mexico,Australia, United Kingdom, Brazil, Germany, Argentina, Chile, China, Canada, and Venezuela. Second Lifeallows all these people who probably could not travel, or could not afford the time and expense to travel,to participate in a simulated face-to-face meeting without energy consumption of traditional travel methods.
More importantly, we got several leads for business. People often ask "Yes, but is there any businessassociated with this?" This time, there was, based on the answers to the questions, several avatars asked for a real sales call to follow-up on the products and offerings they were discussed.
With such a great success, we have already scheduled our next Second Life event, November 8. Mark your calendars! I'll postmore details on the registration process of the November event when available.

Happy Earth Day everyone!
This week I am in Costa Rica to celebrate[Earth Day] and promote IBM's [Smarter Planet strategy] to help solve the world's energy and environmental problems. This is thethird in the series. The first two posts were:
|Here in Costa Rica, they separate their recyclables, and encourage even the hotel guests from other countries to do the same. See my photo on the left for an example.|
This is more than most in the United States will do. We're lucky to get North Americans to just separate all recyclables in one bin separate from all trash in a second bin.
Leaving Arenal, I went to Escazu, a suburb of San Jose, the capital of this country. I met with Patrick, one of the owners of [Exclusive Excursions Travel
] that helped me organize the eco-tourism portion of this trip to Costa Rica.
Most people are familiar with the [star rating system] that rank most hotels from one star (budget class/economy) to five stars (deluxe/luxury). The nicest hotel I've been to was the [Burj Al Arab] in Dubai, which claims a seven star rating. For eco-tourism, there is a similar "Green Leaf" rating system. According to Patrick,the Instituto Costarricense de Turismo [ICT] (tourism board of Costa Rica) rates hotels from one leaf (adopting some measures, like separating recyclables shown above) to five leaves (entirely carbon neutral).This Green Leaf system seems more important to European and Canadian tourists, but those from United States may not even be aware of it.
The food at these hotels vary. The typical dish here for breakfast, lunch and dinner is the Casado, consisting of mostly rice and beans. I have found thatCosta Rica has come up with as many creative ways to combine rice and beans in various proportions as Starbucks® serve various combinations of coffee and milk.The locals might be accustomed to a steady diet of rice and beans for every meal of every day, but those of us from North America aren't! Not counting tourist flatulence, Costa Rica has[pledged to be carbon neutral by 2021], the country's 200th birthday.
Sadly, most folks in the United States don't categorize their hotels with a Green Leaf rating system, nor do they even bother to categorize their recyclables. I spent 18 months in the field doing Information Lifecycle Management (ILM) assessments for clients, and most didn't categorize their data either.So, the next time you have some combination of coffee and milk, whether its a Latte, Misto, Espresso, or Macchiato, remember that the coffee came from acountry trying to be more environmentally responsible, grown by a farmerwho eats a simple diet of rice and beans, and has no problem separating different categories of recyclables. Perhaps you will remember to separate your data, and store it on an information infrastructure based on an environmentally-responsible combination of SSD, FC, SATA and tape, to reduce your costs and minimize your carbon footprint.
We're all on this planet together.
