Now the Thanksgiving Holidays are over, its time to catch up on some Storage Announcements! These actually came out November 20, but many readers were busy with Thanksgiving Thursday, Black Friday, Small Business Saturday, Cyber Monday and Give Back Tuesday, they might have been missed.
IBM Storage has made many exciting announcements in 2018, and it was good to wrap up this year with these!
I'm glad this is the final day of the IBM Systems Technical Conference (STC08) here in Los Angeles.While I enjoyed the conference, one quickly reaches saturation point with all the information presented.
Well, that wraps up my week here in Los Angeles.Special thanks to my two colleagues, Jack Arnold and Glenn Hechler, both from the Tucson Executive Briefing Center,who helped me prepare and review my presentations!

This is the second day of our Systems Technology Conference (STC08) in Los Angeles, California.We have over 700 break-out sessions, packed in 16 times slots across 47 rooms.
Perhaps the only problem with conferences like this is that it can be an overwhelming["fire hose"] of information!

This week I'm in Los Angeles for the Systems Technology Conference (STC '08).We have over 1900 IT professionals attending, of which 1200 IBMers from North America, Latin America,and Asia Pacific regions, as well as another 350 IBM Business Partners. The rest, including me, are world wideor from other areas.
Last January, IBM reorganized its team to be more client-focused. Instead of focused on products, we are nowclient-centric, and have teams to cover our large enterprise systems through direct sales force, business systemsfor sales through our channel business partners, and industry systems for specific areas like deep computing,digital surveillance and retail systems solutions.
In addition to 788 sessions to attend these next four days, we had a few main tent sessions.My third line (my boss' boss' boss) David Gelardi presented Enterprise Systems. This is the group I am in.
Akemi Watanabe presented for Business Systems. Her native language is Japanese, so to do an entire talk inEnglish was quite impressive. Her focus is on SMB accounts, those customers with less than 1000 employeesthat are looking for easy-to-use solutions. She mentioned IBM's new [Blue Business Platform] which includesLotus Foundation Start, an Application Integration Toolkit, and the Global Application Marketplace.
Part of this process is the merger of System p and System i into "POWER" systems, and then offering both midrangeand enterprise versions of these that run AIX, i5/OS and Linux on POWER. It turns out that only 9 percent of ourSystem i customers are only on this platform. Another 87 percent have Windows, so it makes sense to offer i5/OSon BladeCenter, to consolidate Windows servers from HP, Dell or Sun over to IBM.
Meanwhile, IBM's strategy to support Linux has proven successful. 25 percent of x86 servers now run Linux. IBMhas 600 full-time developers for Linux, over 500 of which contributed to the latest 2.6 kernel development. Our ["chiphopper"] program has successfullyported over 900 applications. There are now over 6500 applications that run on Linux applications, on our strategic alliances with Red Hat (RHEL) and Novell (SUSE) distributions of Linux.
Her recommendation to SMB reps: learn POWER systems, BladeCenter, and Linux. I agree!
Mary Coucher presented Industry systems. In addition to the game chips for the Sony Playstation, Nintendo Wii,and Microsoft Xbox-360, this segment focuses on Digital Video Surveillance (DVS), Retail Solutions, Healthcare and Life sciences (HCLS), OEM and embedded solutions, and Deep computing. She mentioned our recently announcediDataPlex solution.
IBM is focused on "real-world-aware" applications, which includes traffic, crime, surveillance, fraud, andRFID enablement. These are streams of data that happen real-time, that need to be dealt with now, not later.
Most people know that IBM has the majority of the top 500 supercomputers, but few may not realize that IBMalso has delivered solutions to the top 100 green companies. IBM success is explained in more detail in this[Press Release].
The group split up to four different platform meetings: Storage, Modular, Power, and Mainframe. Barry Rudolphpresented for the Storage platform. He talked about the explosion in information, business opportunities,risk and cost management. IBM has shifted from being product-focused, to the stack of servers and storage,to our latest focus on solutions across the infrastructure. He mentioned our DARPA win for [PERCS] which stands for prod Exciting times at IBM! technorati tags: STC08, IBM, North America, Latin America, Asia Pacific, David Gelardi, enterprise systems, Akemi Watanabe, Mary Coucher, HCLS, real-world aware, OEM, deep computing, DVS, RHEL, SUSE, HP, Sun, Dell, Storage, Modular, Power, Mainframe, Barry Rudolph, DARPA, PERCS

On his The Storage Architect blog, Chris Evans wrote [Twofor the Price of One]. He asks: why use RAID-1 compared to say a 14+2 RAID-6 configuration which would be much cheaper in terms of the disk cost? Perhpaps without realizing it, answers itwith his post today [XIV part II]:
So, as a drive fails, all drives could be copying to all drives in an attempt to ensure the recreated lost mirrors are well distributed across the subsystem. If this is true, all drives would become busy for read/writes for the rebuild time, rather than rebuild overhead being isolated to just one RAID group.
Let me try to explain. (Note: This is an oversimplification of the actual algorithm in an effortto make it more accessible to most readers, based on written materials I have been provided as partof the acquisition.)
In a typical RAID environment, say 7+P RAID-5, you might have to read 7 drives to rebuild one drive, and in the case of a 14+2 RAID-6, reading 15 drives to rebuild one drive. It turns out the performance bottleneck is the one driveto write, and today's systems can rebuild faster Fibre Channel (FC) drives at about 50-55 MB/sec, and slower ATA disk at around 40-42 MB/sec. At these rates, a 750GB SATA rebuild would take at least 5 hours.
In the IBM XIV Nextra architecture, let's say we have 100 drives. We lose drive 13, and we need to re-replicate any at-risk 1MB objects.An object is at-risk if it is the last and only remaining copy on the system. A 750GB that is 90 percent full wouldhave 700,000 or so at-risk object re-replications to manage. These can be sorted by drive. Drive 1 might have about 7000 objects that need re-replication, drive 2might have slightly more, slightly less, and so on, up to drive 100. The re-replication of objects on these other 99 drives goes through three waves.
Each wave can take as little as 3-5 minutes. The actual algorithm is more complicated than this, as tasks complete early the source and volumes drives are available for re-assignment to another task, but you get the idea. XIV hasdemonstrated the entire process, identifying all at-risk objects, sorting them by drive location, randomly selectingdrive pairs, and then performing most of these tasks in parallel, can be done in 15-20 minutes. Over 40 customershave been using this architecture over the past 2 years, and by now all have probably experienced at least adrive failure to validate this methodology.
In the unlikely event that a second drive fails during this short time, only one of the 99 task fails. The other 98 tasks continue to helpprotect the data. By comparison, in a RAID-5 rebuild, no data is protected until all the blocks are copied.
As for requiring spare capacity on each drive to handle this case, the best disks in production environments aretypically only 85-90 percent full, leaving plenty of spare capacity to handle re-replication process. On average,Linux, UNIX and Windows systems tend to only fill disks 30 to 50 percent full, so the fear there is not enough sparecapacity should not be an issue.
The difference in cost between RAID-1 and RAID-5 becomes minimal as hardware gets cheaper and cheaper. For every $1 dollar you spend on storage hardware, you spend $5-$8 dollars managing the environment. As hardware gets cheaper still, it might even be worth making three copies of every 1MB object, the parallel processto perform re-replications would be the same. This could be done using policy-based management, some data gets triple-copied, and other data gets only double-copied, based on whether the user selected "premium" or "basic" service.
The beauty of this approach is that it works with 100 drives, 1000 drives, or even a million drives. Parallel processingis how supercomputers are able to perform feats of amazing mathematical computations so quickly, and how Web 2.0services like Google and Yahoo can perform web searches so quickly. Spreading the re-replication process acrossmany drives in parallel, rather than performing them serially onto a single drive, is just one of the many uniquefeatures of this new architecture.Read More]

Wrapping up my week's theme of "diversity", with posts on a diverse set of topics,today I will suggest ways to spendyour time while you are walking 10,000 steps per day, as recommended by the authorsof the book "You: On a Diet".
(If you thought this was about the 10,000 steps it might take to implement a storage solution, you should switch over to IBM as your storage vendor. For example, the DS3200 and DS3400 can beimplemented in as little as SIX steps. That's pretty cool.)
Blogs like Lifehacker are an excellent resource for neat littletips and tricks to help you throughout your day, like how to use your iPod, cell phone or computer better, for example. These suggestions are based on the idea that you can walk your 10,000 steps with access to an iPod and cell phone.
Well, that's three suggestions. The next time you complain that there is no time to walk, you now have no excuse.Read More]

Wrapping up this week's exploration on disk system performance, today I willcover the Storage Performance Council (SPC) benchmarks, and why I feel they are relevant to help customers make purchase decisions. This all started to address a comment from EMC blogger Chuck Hollis, who expressed his disappointment in IBM as follows:
You've made representations that SPC testing is somehow relevant to customers' environments, but offered nothing more than platitudes in support of that statement.
Apparently, while everyone else in the blogosphere merely states their opinions and moves on,IBM is held to a higher standard. Fair enough, we're used to that.Let's recap what we covered so far this week:
Today, I will explore ways to apply these metrics to measure and compare storageperformance.
Let's take, for example, an IBM System Storage DS8000 disk system. This has a controller thatsupports various RAID configurations, cache memory, and HDD inside one or more frames.Engineers who are testing individual components of this system might run specifictypes of I/O requests to test out the performance or validate certain processing.
Known affectionately in the industry as the "four corners" test, because you can show them on a box, with writes on the left, reads on the right,hits on the top, and misses on the bottom.Engineers are proud of these results, but these workloads do notreflect any practical production workload. At best, since all I/O requests are oneof these four types, the four corners provide an expectation range from the worst performance (most often write-missin the lower left corner)and the best performance (most often read-hit in the upper right corner) you might get with a real workload.
To understand what is needed to design a test that is more reflective of real business conditions,let's go back to yesterday's discussion of fuel economy of vehicles, with mileage measured in miles per gallon.The How Stuff Works websiteoffers the following description for the two measurements taken by the EPA:
Why two different measurements? Not everyone drives in a city in stop-and-go traffic. Having only one measurement may not reflect the reality that you may travel long distances on the highway. Offering both city and highway measurements allows the consumers to decide which metric relates closer to their actual usage.
Should you expect your actual mileage to be the exact same as the standardized test?Of course not. Nobody drives exactly 11 miles in the city every morning with 23 stops along the way,or 10 miles on the highway at the exact speeds listed.The EPA's famous phrase "your mileage may vary" has been quickly adopted into popular culture's lexicon. All kinds of factors, like weather, distance, anddriving style can cause people to get better or worse mileage than thestandardized tests would estimate.
Want more accurate results that reflect your driving pattern, in specific conditions that you are most likely to drive in? You could rentdifferent vehicles for a week and drive them around yourself, keeping track of whereyou go, and how fast you drove, and how many gallons of gas you purchased, so thatyou can then repeat the process with another rental, and so on, and then use yourown findings to base your comparisons. Perhaps you find that your results are always20% worse than EPA estimates when you drive in the city, and 10% worse when you driveon the highway. Perhaps you have many mountains and hills where you drive, you drive too fast, you run the Air Conditioner too cold, or whatever.
If you did this with five or more vehicles, and ranked them best to worstfrom your own findings, and also ranked them best to worst based on the standardizedresults from the EPA, you likely will find the order to be the same. The vehiclewith the best standardized result will likely also have the best result from your ownexperience with the rental cars. The vehicle with the worst standardized result willlikely match the worst result from your rental cars.
(This will be one of my main points, that standardized estimates don't have to be accurate to beuseful in making comparisons. The comparisons and decisions you would make with estimatesare the same as you would have made with actual results, or customized estimates based on current workloads. Because the rankings are in the same order, they are relevant and useful for making decisions based on those comparisons.)
Most people shopping around for a new vehicle do not have the time or patience to do this with rental cars. Theycan use the EPA-certified standardized results to make a "ball-park" estimate on how much they will spendin gasoline per year, decide only on cars that might go a certain distancebetween two cities on a single tank of gas, or merely to provide ranking of thevehicles being considered. While mileage may not be the only metric used in making a purchase decision, it can certainly be used to help reduce your consideration setand factor in with other attributes, like number of cup-holders, or leather seats.
In this regard, the Storage Performance Council has developed two benchmarks that attempt to reflect normal business usage, similar to "City" and "Highway" driving measurements.
The SPC-2 benchmark was added when people suggested that not everyone runs OLTP anddatabase transactional update workloads, just as the "Highway" measurement was addedto address the fact that not everyone drives in the City.
If you are one of the customers out there willing to spend the time and resources to do your own performance benchmarking, either at your own data center, or with theassistance of a storage provider, I suspect most, if not all, the major vendors(including IBM, EMC and others), and perhaps even some of the smaller start-ups, would be glad to work with you.
If you want to gather performance data of your actual workloads, and use this to estimate how your performance might be with a new or different storage configuration, IBMhas tools to make these estimates, and I suspect (again) that most, if not all, of theother storage vendors have developed similar tools.
For the rest of you who are just looking to decide which storage vendors to invite on your next RFP, and which products you might like to investigate that matchthe level of performance you need for your next project or application deployment,than the SPC benchmarks might help you with this decision. If performance is importantto you, factor these benchmark comparisons with the rest of the attributes you arelooking for in a storage vendor and a storage system.
In my opinion, I feel that for some people, the SPC benchmarks provide some value in this decision making process. They are proportionally correct, in that even ifyour workload gets only a portion of the SPC estimate, that storage systems withfaster benchmarks will provide you better performance than storage systems with lower benchmark results. That is why I feel they can be relevant in makingvalid comparisons for purchase decisions.
Hopefully, I have provided enough "food for thought"on this subject to support why IBM participates in the Storage Performance Council, why the performance of the SAN Volume Controller can be compared to the performanceof other disk systems, and why we at IBM are proud of the recent benchmark results in our recent press release.
Enjoy the weekend!

My post last week [Solid State Disk on DS8000 Disk Systems] kicked up some dust in the comment section.Fellow blogger BarryB (a member of the elite [Anti-Social Media gang from EMC]) tried to imply that 200GB solid state disk (SSD) drives were different or better than the 146GB drives used in IBM System Storage DS8000 disk systems. I pointed out that they are the actual same physical drive, just formatted differently.
To explain the difference, I will first have to go back to regular spinning Hard Disk Drives (HDD). There are variances in manufacturing, so how do you make sure that a spinning disk has AT LEAST the amount of space you are selling it as? The solution is to include extra. This is the same way that rice, flour, and a variety of other commodities are sold. Legally, if it says you are buying a pound or kilo of flour, then it must be AT LEAST that much to be legal labeling. Including some extra is a safe way to comply with the law. In the case of disk capacity, having some spare capacity and the means to use it follows the same general concept.
(Disk capacity is measured in multiples of 1000, in this case a Gigabyte (GB) = 1,000,000,000 bytes, not to be confused with [Gibibyte (GiB)] = 1,073,741,824 bytes, based on multiples of 1024.)
Let's say a manufacturer plans to sell 146GB HDD. We know that in some cases there might be bad sectors on the disk that won't accept written data on day 1, and there are other marginally-bad sectors that might fail to accept written data a few years later, after wear and tear. A manufacturer might design a 156GB drive with 10GB of spare capacity and format this with a defective-sector table that redirects reads/writes of known bad sectors to good ones. When a bad sector is discovered, it is added to the table, and a new sector is assigned out of the spare capacity.Over time, the amount of space that a drive can store diminishes year after year, and once it drops below its rated capacity, it fails to meet its legal requirements. Based on averages of manufacturing runs and material variances, these could then be sold as 146GB drives, with a life expectancy of 3-5 years.
With Solid State Disk, the technology requires a lot of tricks and techniques to stay above the rated capacity. For example, you can format a 256GB drive as a conservative 146GB usable, with an additional 110GB (75 percent) spare capacity to handle all of the wear-leveling. You could lose up to 22GB of cells per year, and still have the rated capacity for the full five-year life expectancy.
Alternatively, you could take a more aggressive format, say 200GB usable, with only 56GB (28 percent) of spare capacity. If you lost 22GB of cells per year, then sometime during the third year, hopefully under warranty, your vendor could replace the drive with a fresh new one, and it should last the rest of the five year time frame. The failed drive, having 190GB or so usable capacity, could then be re-issued legally as a refurbished 146GB drive to someone else.
The wear and tear on SSD happens mostly during erase-write cycles, so for read-intensive workloads, such as boot disks for operating system images, the aggressive 200GB format might be fine, and might last the full five years.For traditional business applications (70 percent read, 30 percent write) or more write-intensive workloads, IBM feels the more conservative 146GB format is a safer bet.
This should be of no surprise to anyone. When it comes to the safety, security and integrity of our client's data, IBM has always emphasized the conservative approach.[Read More]

Looks like fellow blogger and arch nemesis BarryB from EMC is once again stirring up trouble, this time he focuses his attention on IBM's leadership in Solid State Disk (SSD) on the IBM System Storage DS8000 disk systems in his post [IBM's amazing splash dance, part deux], a follow-up to [IBM's amazing splash dance] and multi-vendor tirade [don't miss the amazing vendor flash dance].
(Note: IBM [Guidelines] prevent me from picking blogfights, so this post is only to set the record straight on some misunderstandings, point to some positive press about IBM's leadership in this area, and for me to provide a different point of view.)
First, let's set the record straight on a few things. The [RedPaper is still in draft form] under review, and so some information has not yet been updated to reflect the current situation.
I find it amusing that BarryB's basic argument is that IBM's initial release of SSD disk on DS8000 is less than what the potential architecture could be extended to support much more. Actually, if you look at EMC's November release of Atmos, as well as their most recent announcement of V-Max, they basically say the same thing "Stay Tuned, this is just our initial release, with various restrictions and limitations, but more will follow." Architecturally, IBM DS8000 could support a mix of SSD and non-SSD on the same DA pairs, could support RAID6 and RAID10 as well, and could support larger capacity drives or use higher-capacity read-intensive formats. These could all be done via RPQ if needed, or in a follow-on release.
BarryB's second argument is that IBM is somehow "throwing cold water" on SSD technology. That somehow IBM is trying to discourage people from using SSD by offering disk systems with this technology. IBM offered SSD storage on BladeCenter servers LONG BEFORE any EMC disk system offering, and IBM continues to innovate in ways that allow the best business value of this new technology. Take for example this 24-page IBM Technical Brief:[IBM System z® and System Storage DS8000:Accelerating the SAP® Deposits Management Workload With Solid State Drives]. It is full of example configurations that show that SSD on IBM DS8000 can help in practical business applications. IBM takes a solution view, and worked with DB2, DFSMS, z/OS, High Performance FICON (zHPF), and down the stack to optimize performance to provide real business value innovation. Thanks to this synergy,IBM can provide 90 percent of the performance improvement with only 10 percent of the SSD disk capacity as EMC offerings. Now that's innovative!
The price and performance differences between FC and SATA (what EMC was mostly used to) is only 30-50 percent. But the price and performance differences between SSD and HDD is more than an order of magnitude in some cases 10-30x, similar to the differences between HDD and tape. Of course, if you want hybrid solutions that take best advantage of SSD+HDD, it makes more sense to go to IBM, the leading storage vendor that has been doing HDD+Tape hybrid solutions for the past 30 years. IBM understands this better, and has more experience dealing with these orders of magnitude than EMC.
But don't just take my word for it. Here is an excerpt from Jim Handy, from [Objective Analysis] market research firm, in a recent Weekly Review from [Pund-IT] (Volume 5, Issue 23--May 6, 2009):
As for why STEC put out a press release on their own this week without a corresponding IBM press release, I can only say that IBM already announced all of this support back in February, and I blogged about it in my post [Dynamic Infrastructure - Disk Announcements 1Q09]. This is not the first time one of IBM's suppliers has tried to drum up business in this manner. Intel often funds promotions for IBM System x servers (the leading Intel-based servers in the industry) to help drive more business for their Xeon processor.
So, BarryB, perhaps its time for you to take out your green pen and work up another one of your all-too-common retraction and corrections.[Read More]

A faithful reader of this blog, Tom, sent me a link to Orson Scott Card's article titled[PROGRAMMERS AS BEES (or, how to kill a software company)]. "Is there any truth in this?" Tom asked?Having worked both sides of this fence as I approach my 22 year anniversary at IBM, I guess I can venturesome opinions on this piece. Let's start with this excerpt:
"The environment that nurtures creative programmers kills management and marketing types - and vice versa."
By this, he means "kills" in the UNIX sense, I imagine, and not the "Grand Theft Auto IV" sense.Different people solve problems differently. Some programmers have the luxury that theycan often focus on a single platform, single chipset, single OS, and so on, but Marketing types are tryingto come up with messaging that appeals to a broad audience, from people with business backgrounds to others with moretechnical backgrounds, and that can be more challenging. For programmers, "creative" is an adjective; formarketers, it's a noun.
"Programming is the Great Game. It consumes you, body and soul. When you're caught up in it, nothing else matters."
True. As a storage consultant, I find myself writing code a lot, from small programs, scripts, and even HTML codefor this blog. When you are in your zone, working on something, one can easily lose track of time.
"Here's the secret that every successful software company is based on: You can domesticate programmers the way beekeepers tame bees. You can't exactly communicate with them, but you can get them to swarm in one place and when they're not looking, you can carry off the honey. You keep these bees from stinging by paying them money. More money than they know what to do with. But that's less than you might think."
I have never tamed bees, but many of my friends who are still programmers are motivated by factors other thanmaximizing their income, such as: friendly co-workers, job security, casual attire, and interesting challenges. A few make more than they know what to do with, the rest have
"One way or another, marketers get control. But...control of what? Instead of finding assembly lines of productive workers, they quickly discover that their product is produced by utterly unpredictable, uncooperative, disobedient, and worst of all, unattractive people who resist all attempts at management."
False. Either marketing had control in the first place (ala Apple, Inc.) or they never had. "Control of what?" is the key phrase here.
"The shock is greater for the coder, though. He suddenly finds that alien creatures control his life. Meetings, Schedules, Reports. And now someone demands that he PLAN all his programming and then stick to the plan, never improving, never tweaking, and never, never touching some other team's code."
True. But if you don't like surprises, perhaps software engineering is not the right career path for you.
"The hive has been ruined. The best coders leave. And the marketers, comfortable now because they're surrounded by power neckties and they have things under control, are baffled that each new iteration of their software loses market share as the code bloats and the bugs proliferate. Got to get some better packaging. Yeah, that's it."
This one depends. I've seen teams survive and manage, with junior programmers stepping up to backfill leadership roles, and other times, projects are scrapped, or started anew elsewhere. As for marketers, it doesn't take much to get one baffled, does it?
Thanks for the link, Tom!Read More]
Continuing this week's theme on customer references of IBM's solutions, today I will discussthe success at Kantana Animation Studios.
Of course, I have blogged about Scale-Out File Services [SoFS] before, in my post[More details about IBM clustered scalable NAS]. SoFS is one of the many blended disk-and-tape storage solutionsthat IBM offers. In the case of Kantana, they used [IBM System Storage DS4800 disk] and [IBM System Storage TS3310 tape libraries].
As a film-maker myself (see this sample [Highlights clip])and active member of the Tucson Film Society,I am pleased to see IBM so greatly involved in the film industry. I've had the pleasure to visit some of theseanimation studios myself and meet with other film-makers at various conferences.
For more details on Kantana's implementation, see the [Case Study]Read More]
A client complained that their tape drives were not compressing data as well as it used to. Investigating further reminded me of a scene from the 1970's television show "All in the family", summarized well inAmerican Scientist:
... in one episode of All in the Family, Archie Bunker's son-in-law, Mike, watches Archie put on his shoes and socks. Mike goes into a conniption when Archie puts the sock and shoe completely on one foot first, tying a bow to complete the action, while the other foot remains bare. To Mike, if I remember correctly, the right way to put on shoes and socks is first to put a sock on each foot and only then put the shoes on over them, and only in the same order as the socks. In an ironic development in his character, the politically liberal Mike shows himself to be intolerant of differences in how people do common little things, unaccepting of the fact that there is more than one way to skin a cat or put on one's shoes.
Both agreed that socks go first, then shoes, but the actual deployment was different.
In the case of this customer, a recent change was the use of "encryption" before the data reached the tape drive. In regards to compression and encryption, you should always compress first, then encrypt. Compression algorithms rely on frequency of data, for example the letter "E" appears more often in the English language than the letter "Z". However, once you encrypt data, those data patterns are randomized, and any attempt to compress the data afterwards is wasted effort.
With IBM tape encryption on either the TS1120 or LTO4 tape drives, we compress, then encrypt, the data when it arrives to the tape drive, so that the compression has some chance of getting up to 3:1 reduction. This comp So, just as the case between Archie Bunker and his son-in-law, there are many ways to deploy compression and encryption, just make sure you do them in the right order to get the most benefit.

SNW wrapped up Thursday. As is often the case, a lot of people have left already.
I saw two presentations worth discussing here in this blog.
Continuing my coverage of SNW Spring 2007, Ron and Vincent kicked off Wednesday main tent sessions with more survey questions:
Q1. How secure is your storage network?
Q2. What was the cause of most downtime in last 12 months?
Thornton May, futurist and columnist for ComputerWorld, presented "Storage 3.0: What Comes After, What Comes Next."I have seen several "futurists" present at conferences like this. They all feel the need to explain what their job is, and what it takes to be one. This time, Thornton indicated he was "ridiculously well-travelled, amazingly well-connected, pathologically observant, and brutally honest." His insights:
Gabriel Broner, General Manager of the newly created "Storage Solutions" division of Microsoft, presented "The Drive to Unified Storage". The people sitting around me asked "What does Microsoft have to do with storage?" He defined "Unified Storage" the way we use it for IBM Sytstem Storage N series "a storage unit that provides both file and block level protocol support." Microsoft is using "e-mail" as the model for data access, identifying the need to have "off-line" copies on your PC or laptop that are synced up with "on-line" sources. Features that were typically only available for high-end applications are now being made available to the masses, like "Volume Snapshot" capability in Windows Vista. On the home front, Microsoft recognizes that typically one person acts as the "IT manager" for the family.
Their survey of storage spend of Fortune 1000 companies. It was not clear if this was for Windows environments, or how the data was collected. These numbers don't match what we hear from our UNIX or mainframe customers.
Microsoft is implementing application changes, such as Office 2007, to simplify storage issues. Storage virtualization is the key for the future, he says, stating that Microsoft's "iSCSI target" software support makes files look like block-oriented volumes. Virtualization is now mainstream, and deploying software on standard hardware is the new storage business model. The end goal is to simplify provisioning, device and resource management, without reducing functionality, narrowing the gap between general IT tasks and specific storage tasks.
Craig Lau, NBC Olympic coverage, presented their success story. Look at the number of "hours" of TV Olympic coverage over the years:
NBC now is able to deliver 70 hours of TV programs per day, shown across their seven channels (NBC, CNBC, MSNBC, Brave, USA Network, Telemundo, and HD-tv). The Olympics in Torino, Italy generated 25,000 tapes in 17 days. Their 100,000 tape Olympic repository is starting to deteriorate, and they need to consider conversion to digital format. Their challenge was that footage was difficult to find and producers needed immediate access to time sensitive/critical content.
Their solution was Digital Asset Management, automating indexing and logging, using an IP-based workflows that reduces the number of people at the Olympics location, and allowing content to be sent back to USA for remote editing.The facilities at Torino involved:
NBC is frustrated by the lack of compatability and interoperability in the video format industry. They have been testing MPEG-1 (1.5 Mbps) formats, and plan to deploy a new system using 1080i for the upcoming 2008 Olympics in Beijing. With the new system, they can index footage by athlete, by event, and by human emotional reaction. They can review and edit footage within 30-45 seconds of live coverage, allowing rough edits to be documented as "Edit Decision Lists" that can be e-mailed or put on USB key for others to review.
Although I missed Anil Gupta's "Blogger Event" on Monday, several bloggers did stop by to visit me at the IBMbooth.

I survived my first day at SNW Spring 2007.This is my first time at SNW, but it is very much like many of the other conferences I have been to.It officially started Monday morning with pre-
Tuesday started out with main tent sessions. Ron Milton, VP of ComputerWorld that puts on this conference,and Vincent Franceschini, Chairman of the Board for SNIA, kicked off the event.It didn't take them long to get into the alphabet soup: ILM, ITIL, SMI-S, XAM, IMA, MMA, DDF,MF, DMF, IPSF, SSIF, and SRM.Several hundred people had "voting devices" so that they could participate in "informal" surveys.
Q1. What was the greatest need?
The first keynote speaker was Cora Carmody, CIO of SAIC. In the late 1980s and early 1990s, I did a lot of work with SAIC here in San Diego, and so IBM sent me to San Diego quite frequentlyfor face-to-face meetings with them. Her talk was cryptically titled "Jumbo Shrimp, Info IBM's own Barry Rudolph, presented "Storage in an Age of Inconvenient Truths", dressed up like Oscar-winner andformer USA Vice President Al Gore. Barry's focus was on the growingconcern of over environmental Power and Cooling issues in the data center. According to IDC, the cost of power and cooling an individual server, over its lifetime, now exceeds its acquisition cost. Storage devices are not as bad as servers in this regard. Data centers now consume 1.2% of the worlds energy. Over lunch, I heard Tony Asaro from ESG present "The Need for Highly Virtualized Storage Systems withina Virtualized Data Center." His concern is that there is still a "heavy touch" required to manage storage.Without virtualization, your data center is less than the sum of its parts. Although IBM has been doingstorage virtualization since 1974, Tony mentioned that most storage vendors were "late to the party".He argues that "internal virtualization" inside storage arrays is not enough, you need "external virt I attended a few break-out sessions in the afternoon. Ralph presented "Crisis of Capacity" which covered the drastic actions he had to take to handle power and coolingin their expanding data center during their summer months, where temperatures peak up to 105 degrees. This included creating "hot" and "cold" aisles onhis raised floor by re-organizing the perforated floor tiles, and doing a better job standardizing how cables areconnected to the back of racks and up through the ceiling to maximize airflow. An amp-meter on each power strip was used to measure the powerused at each rack, which allowed them to better prioritize their efforts.

Well, it is Halloween back in the USA. I am in Seoul Korea this week, so it is already Thursday, November 1st here, but thought I would comment on Colin Barker's piece in ZDnet titled[SNW offers the frights].The article starts out with an oversimplification:
The storage industry is enjoying a boom currently thanks to the requirement for IT managers to keep everything. With the possibility of being sued any time by any company for no good reason at all, everyone is keeping everything, or at least all their data. Result? Loads and loads more kit being bought to the benefit of EMC, IBM, HP and every other supplier with any kind of storage product.
While its true that IBM System Storage grew yet again in 3Q07, exceeding our own internal business model, I would not call this an overall "boom" for the storage industry. While companies are growing in "TB capacity" by 30-50%, this translates only to single digit growth in terms of "Dollar revenues". This is because we continue to make storage with declining dollar-per-GB.
One should not confuse what people do with what people are required to do. I am not a lawyer, but most regulations pertaining to storage of information state that certain records need to be kept for a set amount of time, either a fixed period of years, or based on some event. For example, broker/dealers need to keep emails of their clients for six years after the client closes their brokerage account. After those six years, the records can be destroyed.
Unfortunately, many IT managers look at the laws and come up with the simplest solution: keep everything forever. While this might meet the regulators audit requirements, it does expose their employer to subpoenas for data that should have been deleted, and may not be very cost-effective.
The alternative for many IT managers involves having to leave their comfort zone, and talk to their legal counsel, the lines of business, and try to classify their data, determine a set of policies, and inact some forms of enforcement. This is perhaps the "scary" part of the storage of information, it has grown outside the walls of IT, forcing IT managers to interact with the rest of the business to get their jobs done.
Compliance is the only game in town and that is most certainly where the money is.
Anytime an analyst tells you that something is the "only game in town", they are usually wrong. In this case, IBM has had great success in other areas that are not compliance-related. For example, digital video surveillance (DVS) is being used not only to help reduce shoplifting, but also to help identify patterns in customers perusing through aisles and window-shopping. Identifying what people are interested in has proven effective in moving product displays around to better attract buyers and motivate them to make purchases.
Take, the keynote from Andy Monshaw, general manager of IBM storage, and thus a man who is very much in a position to know. He spent his allotted 30 minutes, or whatever, listing all the security, compliance, threats and related issues that are currently making the jobs of most IT manager a cause for concern. Now, there is an argument that suggests that it is absolutely the right thing to do to frighten IT managers into sorting out their issues. They need shaking up say some. Especially analysts.
I helped develop the content of Andy's SNW presentation, working with his speech writers and graphic artists to make a consistent and coherent message fit in the 25 minutes he was given. The challenge with SNW is that we needed to make this presentation applicable across the entire storage industry, without sounding like an infomercial for IBM offerings.
Some people have compared the storage to the "insurance industry", claiming that backups, remote disk mirroring, continuous data protection and other storage related features are costs that can be compared to insurance you pay to protect your home, business, and other assets. You hope you never have to use it, and complain how much it costs, but when bad things happen, you hope it is the best money can buy.
Unlike Y2K, which was a one-time event that had a specific date of occurrence, the threats and risks mentioned by Andy in his presentation may never happen at all, or in other cases, may happen more than once, without knowing when or where. For the sake of your shareholders, and your stakeholders, it is best to be prepared for these possibilities.
The counter argument says that IT companies just smell the money.
Is this a counter argument? Can IBM not both help customers mitigate their risks, and at the same time, turn a profit? Trust me, you do not want to do business with any storage vendor that is not interested in making a profit. The better ones have incorporated addressing client's most pressing challenges into their strategy. I gave a quick summary of IBM's strategy last August in [Day 1 Storage Symposium].
Helping our clients mitigate risks is just one of IBM's core strengths. If you want to learn more, contact your local IBM Business Partner or storage rep.Read More]

On April 2nd IBM announced several key enhancements across the Storwize V5000 portfolio.
The models for the V5000 now include V5010E, 5030E and the V5100.
The V5010E includes two single socket Broadwell DE 2.2GHz, 2 core processor canisters. Each canister supports a maximum of 32GB of RAM.
The V5030E includes the Broadwell DE 1.9GHz, 6 core processor in its two canisters. Each canister supports a maximum of 32GB of RAM.
The V5100 boasts a single Skylake 1.7Ghz processor with 8 cores in each canisters. RAM is increased to a total of 576GB for the entire controller, or 288GB maximum per canister.
From a scale out perspective the V5010E model supports a single controller configuration, while the V5030E and V5100 both support up to two controller clusters. This provides for a maximum of 392 drives in the V5010E and a massive 1520 drives in either the V5030E or V5100 dual controller clusters.
While the new lineup for the V5000 is impressive; regarding the quantity of drives, and the storage available per model will blow your mind.
The V5000E & V5100 versions support the following drive types.
Along with the compute & cache layer enhancements across the V5000 platform, the V5100 receieved a large boost in its storage support. IBM has delivered a solid Flash / Hybrid storage controller player to the markey. In the V5100 model we now support both the Flash Core Modules (FCM) and or NVMe Industry Standard SSD drives. In addition in the expansion drawers you can add even more SAS SSD, 10K and NL-SAS capacity.
The combination of Flash Core Modules and NVMe Industry Standard drives makes the V5100 the perfect low to medium class storage controller.
Both the V5010/30E and the V5100 models offer the following on board interface ports per canister:
The Storwize V5000E models support 1 additional interface card, or 1 SAS host attachment adapter per canister. The optional interface cards available are:
The Storwize V5100 model also supports 1 host interface card, and also optionally up to two SAS Storage Expansion adapters. The adapter interface cards available for the V5100 are:
Regarding the software features for the V5000E and V5100 models, all of the models discussed still include the following features as shown. Specifics on the actual software features is documented below:
Reviewing this information has been eye awaking and though valuable I have only touched on pieces of this latest update for IBM storage.
For those seeking an even deeper depth of knowledge I refer you to my learned colleague Barry Whites blog,

The smart people at the University of Pittsburgh manage five campuses and over 33,000 students, andneeded to create an enterprise storage solution that would give it three key benefits. Of course, they turnedto IBM, the number one overall storage hardware vendor, to deliver.
Here is what Jinx Walton, Director of Computing Services and Systems Development at the University of Pittsburgh, had to say about it...
"The University of Pittsburgh supports large enterprise systems, and the number and complexity of new systems continue to grow. To effectively manage these systems it was necessary to identify an enterprise storage solution that would leverage our existing investments in storage, make allocation of storage flexible and responsive to project needs, provide centralized management, and offer the reliability and stability we require. The integrated IBM storage solution met these requirements"

Happy [Cinco De Mayo] everyone!
I had a great weekend, participating in this year's ["World Laughter Day"] yesterday, and preparingfor tonight's festivities, found me pulling out the various packages from "Simply Dinners" from my freezer.
A Tucson-based company, [Simply Dinners] offers an alternative to restaurant eating.My sister went there, assembled a set of freezer-proof plastic bags containingall the right ingredients based on specific recipes, and gave them to me for my birthday, and they have been sitting in my freezer ever since... until last weekend.
My sister was careful to choose items that fit my [Paleolithic Diet] that my nutritionist has me on. However, I was skepticalthat any plastic bag full of frozen groceries would be any better than anything I could assemble on my own.I did, after all, attend "chef school" and do know how to cook well. Each package was intended to be a "dinner for two" but since I am single, was two meals each for me.
So, I decided to try them out, which would also give me more room in my freezer for incoming items, and theycame out very well. The outside of each plastic bag was a label that explained all the steps required to heatthe food. Partially-cooked vegetables were wrapped in foil, and went in for the last 10 minutes of cooking the meat.The process was straightforward, and the meals were delicious, but nothing I could not have done on my own witha recipe and a trip to the grocery store.
The question is whether someone with little or no skills could achieve similar, or acceptable results. I havefriends who are limited to assembling sandwiches from luncheon meats and cheese slices, as anything involvingheat other than simply boiling water is beyond their skills.
What does this have to do with storage? Blogger Taylor Allis from Sun Microsystems has a few posts[Sun is on to something - Open Storage and An Easier Storage Platform - OpenSolaris"] that explain Sun's recent press release[Sun Microsystems Extends World's First Open Storage Platform with New Services and Tools in OpenSolaris Operating System].
The key difference between "cooking for yourself" and "building your own storage" is that you aren't buildingstorage for just yourself. Unless you are a one-person SMB company, you are building storage that all of youremployees and managers count on to do their jobs, and by extension your customers and stockholders count on.
Of course I had to read responses from others before jumping in with my thoughts.Dave Raffo from Storage Soup writes [Sun going down in storage],feeling this is yet another indication that Sun has lost their mind, recounting previous events that supportthat theory.EMC blogger Mark Twomey in his StorageZilla posts [When Open Isn't] felt a littlebit guilty kicking a competitor when down. EMC blogger Chuck Hollis questions the reasons peoplemight be tempted to even try this in his post [Do-it-Yourself Storage]. Here'san excerpt:
(For EMC, vendor lock-in is great when customers are using and comfortable with EMC products, and awful when they use andare comfortable with storage from someone else. But nobody who is "comfortable" with what they have ever complain about"vendor lock-in" do they? It's the ones who are growing uncomfortable and feel trapped in changing. Howinvolved a company's use of EMC's proprietary interfaces are can greatly determine the obstacles in switching toa different vendor.Of course, if you count yourself as someone growing uncomfortable with your existing storage vendor, IBM can help you fix that problem, but that is a subject for another post.)
Worried about "vendor lock-in"? Try "admin lock-in" where you must keep a storage admin around because he or shewas the one that put your storage together. I've seen several companies held hostage by their system adminsfor home-grown scripts that serve as "duct tape for the enterprise".The other issue is whether you have storage admins who have the necessary hardware and software engineering skillsto put suitable storage together. There are some very smart storage admins I know who could, and others that wouldhave a difficult time with this.
No doubt this is promising for the home office. I myself have taken several PCs that were running older versions of Windows,but not powerful enough to upgrade to Windows Vista, wiped them clean, loaded Linux, and configured them from everythingfrom simple browser workstations to full LAMP application server configurations. While this might sound easy, I am a professional hardwareand software engineer with Linux skills.I have no doubt that someone with sufficient engineering and Solaris skills could put together a storage system for home use.
One area where Sun definitely benefits from this "Open Storage" approach is to develop Solaris skills. I have no personal experience with OpenSolaris, but assume that if you learn it, you would be able to switch overto full Solaris quite easily.Today, most people have Windows, Linux and/or MacOS skills coming into the workforce, and this could be Sun's way of getting new fresh faces who understand Solaris commands to replace retiring "baby boomers". The lack of Sola Certainly, IBM's strategic choice to support Linuxhas been a great success. People learn Linux on their home systems, and at school, and are able to carry those skillsto Linux running on everything from the smallest IBM blade server to IBM's biggest mainframe. The videos on Sun for the "recipes" on how to put together various "storage configurations in ten minutes" appear simplerthan last summer's "How to hack an Apple iPhone to switch away from AT&T" procedures. technorati tags: Cinco De Mayo, World Laughter Day, Simply Dinners, Paleolithic, diet, Taylor Allis, OpenSolaris, Solaris, open storage, Dave Raffo, Mark Twomey, Chuck Hollis, EMC, Sun, Linux, Windows, MacOS, mainframe, blade, recipes, hack, Apple, iPhone, AT&T

I was in Raleigh this week, in business meetings, and had dinner last night at a Japanese Tepanyaki restaurant. The man next to me was dining alone, and said he worked for Cisco, a big company, "Had you heard of it?" he asked. Of course, I told him, I work for IBM, and IBM and Cisco have a strong working relationship, using each others products in both directions. He said he understood why they would use IBM, but why would IBM buy anything from them, and then he said, "Oh yes, your cafeteria".
At this point we realized he was talking about SYSCO, the food company, not Cisco, the storage networking technology partner. We both had a good laugh.
Which brings me to think of other "mis-heard" or "mis-interpreted" items that might have caught people off guard because they sounded similarly.

The movie industry is slowly making the conversion to digital.
For about 25 years, movies were silent, actors acted, text was shown on the screen, and an organ or piano player added the musical score. My mother was a concert pianist, so I grew up listening to all kinds of piano music. Last weekend, while I was in Chicago for St. Patricks Day, we watched and listened to the dueling pianos at a bar called "Howl at the Moon". Those not familiar with this art form can watch this 1-minute video of Star Wars re-imagined as a Silent Movie.
About 80 years ago, "talkies" appeared. The sound was converted to a series of colors that were recorded as a separate strip on the film media itself, hence the name "soundtrack". When the movie ran, the colors would then be converted back to voice and music. While the live piano players were out of jobs, the move to sound created a whole new industry for foley artists, orchestras and comp Now the movie industry is changing again, this time from film to digital format. Thanks to digital, we can now see videos on the internet, such as this set of Impressive Palindromes parody of a Bob Dylan song. While movies are digital when you rent them from the DVD store, download them on iTunes, or play them on YouTube, they are still mostly in analog format on 35mm or 70mm film stock when you see them on the big screen. My first "digital projection" experience was the movie "Ice Age" shown in Denver, Colorado. The theatre owner came out to show us what film stock looks like, and then how small the DVD was that held the digital version. The theatre also showed previews of other movies first on film, then in digital, so that we could see the difference in quality.My second experience was "Star Wars: Attack of the Clones (episode II)", which I saw opening night at the Ziegfeld theatre in New York City. This was a huge theatre, and we had front row seats in the upper balcony. Of course, the transition of film stock to digital projection is just one of the many trends resulting in the fast growth of computer IT storage. Documents transitioned from paper, to being scanned into digital format, to being created digitally using word processing software. Likewise, photographs went from film, to being scanned, to being captured with digital cameras. As with talkies, history repeats itself; the transition to digital projection is not going smoothly.NPR's Laura Sydell reports thatDigital Projection in Theaters Slowed by Dispute. The dispute is between movie production companies and theatre owners. Currently, it is quite expensive to send out film stock to all the theatres, so the transition to digital will save the movie production companies lots of money. On the other hand, installing digital projection equipment will be costly for theatre owners. How the two groups will share the burdensome costs to convert this infrastructure is still under negotiation. As a fan of going to the movies, I hope they resolve this dispute soon.

This was a huge theatre, and we had front row seats in the upper balcony.
Of course, the transition of film stock to digital projection is just one of the many trends resulting in the fast growth of computer IT storage. Documents transitioned from paper, to being scanned into digital format, to being created digitally using word processing software. Likewise, photographs went from film, to being scanned, to being captured with digital cameras.
As with talkies, history repeats itself; the transition to digital projection is not going smoothly.NPR's Laura Sydell reports thatDigital Projection in Theaters Slowed by Dispute. The dispute is between movie production companies and theatre owners. Currently, it is quite expensive to send out film stock to all the theatres, so the transition to digital will save the movie production companies lots of money. On the other hand, installing digital projection equipment will be costly for theatre owners. How the two groups will share the burdensome costs to convert this infrastructure is still under negotiation.
As a fan of going to the movies, I hope they resolve this dispute soon.

Can Structured Query Language [SQL] be considered a storage protocol?
Several months ago, I was asked to review a book on SQL, titled appropriately enough "The Complete Idiot's Guide to SQL", by Steven Holzner, Ph.D. As a published author myself, I get a lot of these requests, and I agreed in this case, given that SQL was invented by IBM, and is a good fundamental skill to have for Business Analytics and Database Management.
(FTC Disclosure: I work for IBM but was not part of the SQL development team. I was provided a copy of this book for free to review it. I was not paid to mention this book, nor told what to write. I do not know the author personally nor anyone that works for his publicist. All of my opinions of the book in this blog post are my own.)
Despite an agreed-upon standard for SQL, each relational database management system (RDBMS) has decided to customize it for their own purposes. First, SQL can be quite wordy, so some RDBMS have made certain keywords optional. Second, RDBMS offer extra features by adding keywords or programming language extentions, options or parameters above and beyond what the SQL standard calls for. Third, the SQL standard has changed over the years, and some RDBMS have opted to keep some backward compatibility with their prior releases. Fourth, some RDBMS want to discourage people from easily porting code from one RDBMS to another, known in the industry as vendor lock-in.
Throughout my career, I have managed various databases, including Informix, DB2, MySQL, and Microsoft SQL Server, so I am quite familiar with the differences in SQL and the problems and implications that arise.
Most authors who want to write about SQL typically make a choice between (a) stick to the SQL standard, and expect the reader to customize the examples to their particular DBMS; or (b) stick to a single RDBMS implemenation, and offer examples that may not work on other RDBMS.
I found the book "The Complete Idiot's Guide to SQL" covered the basics quite well, but with an odd twist. The basics include creating databases and tables, defining columns, inserting and deleting rows, updating fields, and performing queries or joins. The odd twist is that Steven does not make the typical choice above, but rather shows how the various DBMS are different than standard SQL syntax, with actual working examples for different RDBMS.
You might be thinking to yourself that only an idiot would work in a place that had to require knowledge of multiple RDBMS. The sad truth is that most of the medium and large companies I speak to have two or more in production. This is either through acquisitions, or in some cases, individual business units or departments implementing their own via the [Shadow IT].
(For those who want to learn SQL and try out the examples in this book, IBM offers a free version of DB2 called [DB2-C Express] that runs on Windows, Linux, Mac OS, and Solaris.)
Last week, while I was in Russia for the [Edge Comes to You] event, I was interviewed by a journalist from [Storage News] on various topics. One question stuck me as strange. He asked why I did not mention IBM's acquisition of Netezza in my keynote session about storage. I had to explain that Netezza was not in the IBM System Storage product line, it is in a different group, under Business Analytics, where it belongs.
While it is true that Netezza can store data, because it has storage components inside, the same could also be said about nearly every other piece of IT equipment, from servers with internal disk, to digital cameras, smart phones and portable music players. They can all be considered storage devices, but doing so would undermine what differentiates them from one another.
Which brings me back to my original question: Should we consider SQL to be a storage protocol? For the longest time, IT folks only considered block-based interfaces as storage protocols, then we added file-based interfaces like CIFS and NFS, and we also have object-based interfaces, such as IBM's Object Access Method (OAM) and the System Storage Archive Manager (SSAM) API. Could SQL interfaces be the next storage protocol?
Let me know what you think on this. Leave a comment below.
