Perhaps the recent financial meltdown is making storage vendors nervous.Both IBM and EMC gained market share in 3Q08, but EMC is acting strangelyat IBM's latest series of plays and announcements. Almost contradictory!
- Benchmarks bad, rely on your own in-house evaluations instead
Let's start with fellow blogger Barry Burke from EMC, who offers his latest post[Benchmarketing Badly] with commentaryabout Enterprise Strategy Group's [DS5300 Lab Validation Report]. The IBM System Storage DS5300 is one of IBM's latest midrange disk systems recently announced. Take for example this excerpt from BarryB's blog post:
"I was pleasantly surprised to learn that both IBM and ESG agree with me about the relevance and importance of the Storage Performance Council benchmarks.Nowhere in the ESG report says this, nor have I found any public statements from either IBM nor ESG that makes this claim. Instead, the ESG report explains that traditional benchmarks from the Storage Performance Council [SPC] focus on a single, specific workload, and ESG has chosen to complement this with a variety of other benchmarks to perform their product validation, including VMware's "VMmark", Oracle's Orion Utility, and Microsoft's JetStress.
That is, SPC's are a meaningless tool by which to measure or compare enterprise storage arrays."
Benchmarks provide prospective clients additional information to make purchasedecisions. IBM understands this, ESG understands this, and other well-respected companies like VMware, Oracle and Microsoft understand this. EMC is afraid that benchmarks mightencourage a client to "mistakenly" purchase a faster IBM product than a slower EMC product. Sunshine makes a great disinfectant, but EMC (and vampires) prefer their respective "prospects" remain in the dark.
Perhaps stranger still is BarryB's postscript. Here's an excerpt:
"... a customer here asked me if EMC would be willing to participate in an initiative to get multiple storage vendors to collaborate on truly representative real-world "enterprise-class" benchmarks, and I reassured him that I would personally sponsor active and objective participation in such an effort - IF he could get the others to join in with similar intent."
As I understand it, EMC was once part of the Storage Performance Council a long time ago, then chose to drop out of it. Why re-invent the wheel by creating yet another storage industry benchmark group? EMC is welcome to come back to SPC anytime! In addition to the SCP-1 and SPC-2 workloads, there is work underway for an SPC-3 benchmark. Each SPC workload provides additional insight for product comparisons to help with purchase decisions. If EMC can suggest an SPC-4 benchmark that it feels is more representative of real-world conditions, they are welcome to join the SPC party and make that a reality.
The old adage applies: ["It's better to light a candle than curse the darkness"]. EMC has been cursing the lack of what it considers to be acceptable benchmarks but has yet to offer anything more realistic or representative than SPC.What does EMC suggest you do instead? Get an evaluation box and run your own workloads and see for yourself! EMC has in the past offered evaluation units specifically for this purpose.
- In-house evaluations bad, it's a trap!
Certainly, if you have the time and staff to run your own evaluation, with your own applications in your own environment, then I agree with EMC that this can provide better insight for your particular situation than standardized benchmarks.
In fact, that is exactly what IBM is doing for IBM XIV storage units, which are designed for Web 2.0 and Digital Archive workloads that current SPC benchmarks don't focus on. Fellow blogger Chuck Hollis from EMC opines in his post[Get yer free XIV!]. Here's an excerpt:
"Now that I think about it, this could get ugly. Imagine a customer who puts one on the floor to evaluate it, and -- in a moment of desperation or inattention -- puts production data on the device.
Nobody was paying attention, and there you are. Now IBM comes calling for their box back, and you've got a choice as to whether to go ahead and sign the P.O., or migrate all your data off the thing. Maybe they'll sell you an SVC to do this?
Yuck. I bet that happens more than once. And I can't believe that IBM (or the folks at XIV) aren't aware of this potentially happening."
Perhaps Chuck is speaking from experience here, as this may have happened with customers with EMC evaluation boxes, and is afraid this could happen with IBM XIV. I don't see anything unique about IBM XIV in the above concern. Typical evaluations involve copying test data onto the box, test it out with some particular application or workload, and then delete the data no longer required. Repeat as needed. Moving data off an IBM XIV is aseasy as moving data off an EMC DMX, EMC CLARiiON or EMC Celerra, and I am sure IBM wouldgladly demonstrate this on any EMC gear you now have.
Thanks to its clever RAID-X implementation, losing data on an IBM XIV is less likely thanlosing data on any RAID-5 based disk array from any storage vendor. Of course, there will always be skeptics about new technology that will want to try the box out for themselves.
If EMC thought the IBM XIV had nothing unique to offer, that its performance was just "OK",and is not as easy to manage as IBM says it is, then you would think EMC would gladly encourage such evaluations and comparisons, right?
No, I think EMC is afraid that companies will discover what they already know, that IBM has quality products that would stand a fair chance of side-by-side comparisons with their own offerings.We have enough fear, uncertainty and doubt from our current meltdown of the global financial markets, don't let EMC add any more.
Have a safe and fun Halloween! If you need to add some light to your otherwise dark surroundings, consider some of these ideas for [Jack-O-Lanterns]!

Well, it's Tuesday again, and that means more announcements from IBM!
In conjunction with IBM's new [System z10 Business Class (BC)] mainframe designed for Small and Medium-sized Businesses (SMB), IBM also announced related storage productenhancements.
- DS6000 series
Yes, it's alive! Contrary to the FUD you might have read from our competitors, IBM continues to sell thousands and thousands of IBM System Storage DS6800 disk systems, and now enhances them with the optionfor 450GB 15K RPM drives. What is nice about these 450GB drives is that they are as fast or faster* than 300GBdrives, so the typical trade-off between performance and capacity do not apply.
(* I compared Seagate 15.6K (450GB) with 15.5K (300GB) models.
|450GB drives||300GB drives|
|Avg Seek time (Read)||3.4ms||3.5 ms|
|Avg Seek time (Write)||3.9ms||4.0 ms|
|Full Seek time (Read)||6.43ms||6.7 ms|
|Full Seek time (Write)||7.12ms||7.4 ms|
|Sustained Bandwidth||112-171 MB/sec||73-125 MB/sec|
This may or may not result in application performance improvements, depending on workload pattern. Your mileage may vary.)
Our clients report back that these are incredibly stable systems that they don't have toworry about. This enhancement applies to both the [511/EX1 models] and [522/EX2 models].
- DS8000 series
Understanding that clients want complete solutions from single vendors, IBM offers synergy between System z and the IBM System Storage DS8000 disk systems. The latest R4.1 microcode upgrade offers two key features onthe various models [2107,
2421, 2422, 2423, and 2424].
- zHPF - High Performance FICON for System z. IBM was able to increase the throughput on 4 Gbps links. For OLTP workloads randomly accessing 4KB blocks, IBM internal tests showed zHPF doubled performance from 13,000 IOPSto 26,000 IOPS per channel. For sequential workloads, such as batch processing, zHPF increased performance 50 percent, from 350 MB/sec to 525 MB/sec.
- In February, IBM previewed[IncrementalResync] for z/OS Metro Global Mirror. However, some concepts are better explained with pictures.
One way to set up a 3-site disaster recovery protection is to have your production synchronously mirrored to a second site nearby, and at the same time asynchronously mirrored to a remote location. On the System z, you can have site "A" using synchronous IBM System Storage Metro Mirror over to nearby site "B", and also have site "A" sending data over to site "C" asynchronously using z/OS Global Mirror. This is called "z/OS Metro Global Mirror".
In the past, if the disk system in site A failed, you would switch over to site B, which would have to resend send all the data again to site C to be resynchronized. This is because site B was not tracking what the System Data Mover (SDM) reader had or had not yet processed.
With DS8000 4.1, the "incremental resync" function that, along with using IBM HyperSwap, requires site B to only send and resync the data that was in-flight when the outage occurred. When you compare the difference in sending this limited amount of in-flight data with the traditional complete volume of data, you can see how "Incremental Resync" can resynchronize the data 95% faster, and also greatly decrease your bandwidth requirements. This reduces the risk in case a subsequent outage occurs.
- TS7700 series
Introduced originally in 1997 as the IBM Virtual Tape Server (VTS), the [IBMSystem Storage TS7700] series supports Grid capabilityto replicate tape image data across locations. Here's a quick recap of today's announcement:
- Existing TS7740 can be upgraded up to 9TB of disk cache. New models can have up to 13TB of disk cache.
- A new "tape-less" TS7720 that has up to 70TB of disk cache.
- Integrate Library Management support. I discussed[IntegratedRemovable Media Manager (IRMM)] before, and this is basically IRMM inside. For those with TS3500 tape libraries,this support eliminates the need for a separate IBM 3953 L05 Library Manager.
- TS1130 back-end tape drive support. These are the fastest 1TB drives in the industry, with support of built-in encryption, and now can be used asthe physical tape back-end for the virtual tape TS7740 repository.
While our competitors might be boarding up their windows in preparation for the economic downturn in the USAeconomy, IBM remains generating solid results. San Jose Mercury News has an article that discusses this titled[IBM's 3Q profit strong on global sales].There has never been a better time to buy from, or invest in, IBM!

Last month, HP and Oracle jointly announced their new "Exadata Storage Server".This solution involves HP server and storage paired up with Oracle software, designed for Data Warehouse andBusiness Intelligence workloads (DW/BI).
I immediately recognized the Exadata Storage Server as a "me too" product, copying the idea from IBM's [InfoSphere Balanced Warehouse]which combines IBM servers, IBM storage and IBM's DB2 database software to accomplish this, but from a singlevendor, rather than a collaboration of two vendors.The Balanced Warehouse has been around for a while. I even blogged about this last year, in my post[IBMCombo trounces HP and Sun] when IBM announced its latest E7100 model. IBM offers three different sizes: C-class for smaller SMB workloads, D-class for moderate size workloads, and E-class for large enterprise workloads.
One would think that since IBM and Oracle are the top two database software vendors, and IBM and HP are the toptwo storage hardware vendors, that IBM would be upset or nervous on this announcement. We're not. I would gladlyrecommend comparing IBM offerings with anything HP and Oracle have to offer. And with IBM's acquisition of Cognos,IBM has made a bold statement that it is serious about competing in the DW/BI market space.
But apparently, it struck a nerve over at EMC.
Fellow blogger Chuck Hollis from EMC went on the attack, and Oracle blogger Kevin Closson went on the defensive.For those readers who do not follow either, here is the latest chain of events:
When it comes to blog fights like these, there are no clear winners or losers, but hopefully, if done respectfully,can benefit everyone involved, giving readers insight to the products as well as the company cultures that produce them.Let's see how each side fared:
Chuck implies that HP doesn't understand databases and Oracle doesn't understand server and storage hardware, socobbling together a solution based on this two-vendor collaboration doesn't make sense to him. The few I know who work at HP and Oracle are smart people, so I suspect this is more a claim againsteach company's "core strengths". Few would associate HP with database knowledge, or Oracle with hardware expertise,so I give Chuck a point on this one.
Of course, Chuck doesn't have deep, inside knowledge of this new offering, nor do I for that matter, and Kevin is patient enough to correct all of Chuck's mistaken assumptions and assertions. Kevin understands that EMC's "core strengths" isn't in servers or databases, so he explains things in simple enough terms that EMC employees can understand, so I give Kevin a point on this one.
So, what does Chuck propose as the preferred alternative: a three-way collaboration! EMC's counter-proposal is to cobble together [Dell servers, EMC storage, and Oracle software].
If two is bad, then three is worse! How much bubble gum and bailing wire do you need in your data center? The better option is to go to the one company that offers it all and brings it together into a single solution: IBM InfoSphere Balanced Warehouse.

Continuing this week's theme on dealing with the global economic meltdown, recession and financial crisis, I found a great video that recaps IBM CEO Sam Palmisano's recommendations to being more competitive in thisenvironment.
|In a recent speech to business leaders, Sam outlined what he sees as the four most importantsteps to thriving in the global economy. The highlights can be seen here in this [2-minute video]on IBM's "Forward View" eMagazine.|

Lakota Industries made news with the introduction of its [Sarah-Cuda Hunting Bow
], named after moose-huntingU.S. Vice President nominee and Governor of Alaska [Sarah Palin
]. This has all the same features as their other high-end hunting bows, but is lighter, smaller and available in Pink Camo. This "pink-it-and-shrink-it" move was designed to broaden the market share of hunting bows by reaching out to the needs of women hunters.
Not to be outdone, today, at the Storage Networking World Conference, IBM announced the new IBM System Storage SAN Volume Controller Entry Edition [SVC EE].
|The new SVC Entry Edition, available in Flamingo Pink* or traditional Raven Black.|
* RPQ required. Default color is Raven Black.
You might be thinking: "Wait! IBM SVC is already the leading storage virtualization product among SMB clients today,why introduce a less expensive model?" With the global economy in the tank, IBM thought it would be nice to help outour smaller SMB clients with this new option.
This new offering is actually a combination of new software (SVC 4.3.1) and new hardware (2145-8A4). Here are thekey differences:
|SVC Classic||SVC EE|
|Licensing||by usable capacity managed, up to 8 PB||by number of disk drives, up to 60 drives|
|Hardware||2145-4F2, 8F2, 8F4, 8G4, 8A4||2145-8A4|
|Cluster size||1, 2, 3 or 4 node-pairs, depending on performance requirements||only one node-pair needed|
|Copy Services||FlashCopy, Metro Mirror and Global Mirror, licensed by subset of capacity used||FlashCopy, Metro Mirror and Global Mirror, but with simplified licensing|
The SVC EE is not a "dumbed-down" version of the SVC Classic. It has all the features and functions of theSVC Classic, including thin provisioning with "Space-efficient volumes", Quality of Service (QoS) performance prioritization for more important applications, point-in-time FlashCopy, and both synchronous and asynchronous disk mirroring (Metro and Global Mirror).
While IBM has not yet have SPC-1 benchmarks published, IBM is positioning the SVC EE as roughly 60 percent of the performance, at 60 percent of the list price, compared to a comparable SVC Classic 2145-8G4 configuration. The SVC Classic is already one of the fastest disk systems in the industry. By comparison, the SVC EE is twice as fast as the original SVC 2145-4F2 introduced five years ago.If you outgrow the SVC EE, no problem! The 2145-8A4 can be used in traditional SVC Classic mode, and the SVC EE software can be converted into the SVC Classic software license for upgrade purposes, protecting your originalinvestment!
For those considering an HP EVA 4400 or EMC CX-4 disk system, you might want to look at combining an SVC EE with [IBM System Storage DS3400] disk. The combination offers more features and capabilities, and helps reduce your IT costs at the same time.
And if you are worried you can't afford it right now, IBM Global Financing is offering a ["Why Wait?" world-wide deferral of interest and payments] for 90 days, so you don't have to make your first payment until 2009, applicable to all IBM System Storage products, including the SVC EE, SVC Classic and DS3400 disk systems.

As the popular idiom goes, ["Every cloud has a silver lining"
], and perhaps there are some things that we gain from the recent financial collapse of the global world markets.
Let's examine some of these:
- Consolidation and the [Economies of Scale]
As financial firms focus on costs, the IT departments will have an opportunity to consolidate their servers, networks and storage equipment. Consolidating disk and tape resources, implementing storage virtualization, and reducingenergy costs might get a boost from this crisis. Consolidating disparate storage resources to a big SoFS, XIV,DS8000 disk system, or TS3500 tape library might greatly help reduce costs.
- Establishing enterprise-wide Storage Resource Management (SRM)
Having mixed vendor environments that result from such mergers and acquisitions can be complicated to manage. Thankfully, IBM TotalStorage Productivity Centermanages both IBM and non-IBM equipment, based on open industry standards like SMI-S and WBEM.Merged companies might let go IT people with limited vendor-specific knowledge, but keep the ones familiar withcross-vendor infrastructure management skills and ITIL certification.
- Comparing different vendor equipment
It seems that often times when there is a merger or acquisition, the two companies were using different storage gear from different vendors. IBM has made some incredible improvements over the past three years, in both performance enhancements and energy efficiency, but many companies with non-IBM equipment may not be aware of them.If there was ever a time to perform a side-by-side comparison between IBM and non-IBM equipment, here isyour chance.

There's some good discussion in the comments section over at Robin Harris' StorageMojo
blog for hispost [Building a 1.8 Exabyte Data Center
].To summarize, a student is working on a research archive and asked Robin Harris for his opinion. The archive will consist of 20-40 million files averaging 90 GB in size each, for a total of 1800 PB or 1.8 EB. By comparison, anIBM DS8300 with five frames tops out at 512TB, so it would take nearly 3600 of these to hold 1.8 EB. While this might seem like a ridiculous amount of data, I think the discussion is valid as our world is certainly headed in that direction.
IBM works with a lot of research firms, and the solution is to put most of this data on tape, with just enough disk for specific analysis. Robin mentions a configurion with Sun Fire 4540 disk systems (aka Thumper). Despite Sun Microsystems' recent [$1.7 Billion dollar quarterly loss], I think even the experts at Sun would recommend a blended disk-and-tape solution for this situation.
Take for example IBM's Scale Out File Services [SoFS] which today handles 2-3 billion files in a single global file system, so 20-40 million would present no problem. SoFS supports a mix of disk and tape, with built-in movement, so that files that were referenced would automatically be moved to disk when needed, and moved back to tape when no longer required, based on policies set by the administrator. Depending on the analysis, you may only need 1 PB or less of disk to perform the work, which can easily be accomplished with a handful of disk systems, such as IBM DS8300 or IBM XIV, for example.
The rest would be on tape. Let's consider using the IBM TS3500 with [S24 High Density] frames. A singleTS3500 tape library with fifteen of these HD frames could hold 45PB of data, assuming 3:1 compression on 1TB-size 3592 cartridges. You wouldneed 40 (forty) of these libraries to get to the full 1800 PB required, and these could hold even more as higher capacity cartridges are developed. IBM has customers with over 40 tape libraries today (not all with these HD frames, of course), but the dimensions and scale that IBM is capable lies within this scope.
(For LTO fans, fifteen S54 frames would hold 32PB of data, assuming 2:1 compression on 800GB-size LTO-4 cartridges.so you would need 57 libraries instead of 40 in the above example.)
This blended disk-and-tape approach would drastically reduce the floorspace and electricity requirements when compared against all-disk configurations discussed in the post.
People are rediscovering tape in a whole new light. ComputerWorld recently came out with an 11-page Technology Brief titled [The Business Value of Tape Storage],sponsored by Dell. (Note: While Dell is a competitor to IBM for some aspects of their business, they OEM their tape storage systems from IBM, so in that respect, I can refer to them as a technology partner.) Here are some excerpts from the ComputerWorld brief:
For IT managers, the question isnot whether to use tape, but whereand how to best use tape as part of acomprehensive, tiered storage architecture.In the modern storage architecture,tape plays a role not onlyin data backup, but also in long-termarchiving and compliance.
“Long-term archiving is the primaryreason any company shoulduse tape these days,” says MikeKarp, senior analyst at EnterpriseManagement Associates in Boulder,Colo. Companies are increasinglylikely to use disk in conjunctionwith tape for backup, but for long-termarchiving needs, tape remainsunbeatable.
After factoring inacquisition costs of equipment andmedia, as well as electricity and datacenter floor space, Clipper Groupfound that the total cost of archivingsolutions based on SATA disk, theleast expensive disk, was up to 23times more expensive than archivingsolutions involving tape. Calculatingenergy costs for the competing approaches,the costs for disk jumpedto 290 times that of tape.
“Tape isalways the winner anywhere costtrumps anything else,” says Karp.No matter how the cost is figured,tape is less expensive.
Beyond IT familiarity with tape,analysts point to other reasons whyorganizations will likely keep tapein their IT storage infrastructures.Energy savings, for example, is themost recent reason to stick withtape. “The economics of tape arepretty compelling, especially whenyou figure in the cost of power,”Schulz says.
So, whether you are planning for an Exabyte-scale data center, or merely questioning the logic of a disk-for-everything storage approach, you might want to consider tape. It's "green" for the environment, and less expensive on your budget.

Well, it's Tuesday again, and that means more IBM announcements!
- Storage Area Network (SAN)
IBM and Cisco announced [three new blades] for the Cisco MDS 9500 seriesdirectors: 24-port 8 Gbps, 48-port 8 Gbps, and 4/44 blended. The 4/44blended has 4 of the faster 8 Gbps ports, and 44 of the 4 Gpbs ports,so that you can auto-negotiate down to 1 Gbps for your older gear, andstill take advantage of the faster 8 Gbps speeds during the transition.
On the Brocade side, IBM announced the newIBM System Storage Data Center Fabric Manager [DCFM] V10 software. This replaces the products formerly known as BrocadeFabric Manager and McData Enterprise Fabric Connection Manager (EFCM).This software can support up to 24 distinct fabrics, up to 9000 ports,including a mix of FCP, FICON, FCIP and iSCSI protocols.
And if you need help setting up your SAN, IBM has recently renamed itsservices, formerly known as "IBM Implementation Services for SAN fabric components" to ["IBM Storage and Data Product Services - IBM Implementation Services for storage software - SAN fabric components"]. There is no change to the services actually provided, which have been available since 2003, but IBM felt that renaming it would make good press coverage.
(On a related note, I heard that Microsoft is planning to rename "Windows Vista" to "Windows 7" next year! Like we say here in Tucson,if it ends in "-ista" it is going to fail in the marketplace! Perhaps EMC should rename their storage virtualization product to "In-7"?).
- IBM System Storage DR550
IBM announced today that it now supports [RAID 6 onthe DR550] compliance and retention storage system.
There are a few RAID-5 based EMC Centera customers out there who have notyet switched over to the IBM DR550, and now this might be just the littlenudge they need. For long-term retention of regulatory compliance data,RAID-5 doesn't cut it, you need an advanced RAID scheme, such as RAID-6, RAID-DP or RAID-X.
The DR550 provides non-erasable, non-rewriteable (NENR) storage supportto keep retention-managed data on disk and tape media. It supports 1 TBSATA disk drives and 1TB tape cartridges to provide high capacity at lowcost and "green" low energy consumption.
- IBM System Storage N series
Several of our disk systems got improved and enhanced. Let's start withthe IBM System Storage N series[hardware and software] enhancements. IBM now offers high-speed 450GB 15K RPM drives. These are Fibre Channel (FC) drives for the EXN4000 expansion drawers, and Serial Attached SCSI (SAS) drives for the entry-levelN3300 and N3600 models.
The "gateway" models now support a variety of functions that were formerlyonly available on the appliance models. This includes Advanced Single Instance Storage (A-SIS), Disk Sanitization, and FlexScale.
A-SIS is IBM's "other" deduplication function, and I talked about this in my post [A-SIS Storage Savings Estimator Tool]. Disk Sanitization will physicallywrite ones and zeros over existing data to eliminate it, what IBM sometimes calls "Data Shredding".
The last feature, FlexScale, might be new for many. It is software toenable to use of the "Performance Accelerator Module" (PAM). The PAM isa PCI-Express card with 16GB on-board RAM that acts as a secondary cachebehind main memory of the N series controller. Depending on the model,you can have one to five of these cards fit into the controller itself,boosting random read performance, metadata access, and write block destage.
- IBM System Storage DS5000
IBM's latest entry into the DS family has been hugely successful.In addition to Linux, Windows and AIX, the DS5000 now supports [Novell Netware and Sun Solaris] operating systems.
For infrastructure management, IBM has enhanced the Remote Support Manager [RSM]that supports DS3000 and DS4000 has been extended to support DS5000 as well. This software can monitor up to 50 disk systems, will e-mail alerts to IBM when something goes wrong, and allow IBM to dial in via modem to get more diagnostic information to improve service to the client. Also, the IBM System Storage Productivity Center [SSPC]which now supports the DS8000 and SAN Volume Controller (SVC) has been extended to also support the DS5000.
- IBM XIV Storage System
In addition to 1-year and 3-year maintenance agreements, IBM now offers[2-year, 4-year and 5-year] software maintenance agreements.
- RFID labels for IBM tape media
IBM 3589 (20-pack of LTO cartridges) and IBM 3599 (20-pack of 3592 cartridges for TS1100 series)now offer [RFID labels]. These labels match the volume serial (VOLSER) with a 216-bit unique identifier and 256 bits of user-defined content. This can help with tape inventory,and to prevent people from walking out of the building with a tape cartridge stuffed in their jacket.
- 32GB memory stick
While not technically part of the IBM System Storage matrix of offerings, Lenovo announced their new[Essential Memory Key] which holds 32GB of memory and workswith both USB 1.1 and USB 2.0 protocols.
I wish I could say this is it for the IBM announcements for October, given that this is the last Tuesday of the month, but there are three days left, so there might be just a few more!

In collaboration with [The Feminist Press] and the[National Science Foundation], IBM launched today a new Web site called ["Under the Microscope"]to encourage young women to pursue education and careers in science, technology, engineering and math (STEM).
The site is filled with information. One item I found particularly interesting was Science Debate 2008's[14 Questions about Science] where the top two U.S. presidential candidates answer questions about science. Barack Obama's answers inDemocratic blue, and John McCain's answers in Republican red.
This is just one of the ways IBM is trying to reach out and help our next generation.
