Since Clod Barrera introduced IBM's Smarter Computing initiative during yesterday's keynote session, I took it to the next lower level, with a presentation on how IBM's Storage Strategy aligns with the Smarter Computing approach.
Deduplication -- It's Not Magic, It's Math!
Local IBMer Paul Rizio presented this high-level session on the concepts of data deduplication, and how it is implemented in IBM's N series, TSM and ProtecTIER virtual tape libraries. I first met Paul earlier this year when we were both instructors at Top Gun classes we held in Auckland, New Zealand and Sydney, Australia.
IBM Information Archive for files, email and eDiscovery
This was a reprise of my presentation that I gave last July in Orlando, Florida (see my blog post [IBM Storage University - Day 1]). I explained the differences between backup and archive, the differences between Tivoli Storage Manager and System Storage Archive Manager, and the Information Archive (IA) The Information Archive for files, email and eDiscovery bundle combines IA hardware with content collectors for files and email, eDiscovery analyzer and eDiscovery manager software.
What are Industry Consultants saying about IBM Storage?
Vic Peltz, from our IBM Almaden Research Center, presented this lively presentation on how IT industry analysts gather their information and structure their findings into various models. For many in the audience, this would be their first exposure to concepts like a "Magic Quadrant", "MarketScope" and the various stages of the "Hype Cycle".
IBM SONAS and the Smart Business Storage Cloud
The title of this session just rolls off my tongue, similar to "James and the Giant Peach" or "Harold and the Purple Crayon". I had presented this back in July (see my blog post [IBM Storage University - Cloud Storage]). This time, I had updated the materials to reflect the new SONAS R1.3 release, and the new IBM SmartCloud offerings announced last month.
Of course the big news is that U.S. President Barack Obama is here in Australia, with a stop in Canberra (not far from Melbourne), followed by a stop in Darwin on the north side of this country. This is his first official visit to Australia as president.
Earlier this week, EMC announced its Symmetrix V-Max, following two trends in the industry:
Using Roman numerals. The "V" here is for FIVE, as this is the successor to the DMX-3 and DMX-4. EMC might have gotten the idea from IBM's success with the XIV (which does refer to the number 14, specifically the 14th class of a Talpiot program in Israel that the founders of XIV graduated from).
Adding "-Max", "-Monkey" or "2.0" at the end of things to make them sound more cool and to appeal to a younger, hipper audience. EMC might have gotten this idea from Pepsi-Max (... a taste of storage for the next generation?)
I took a cue from President Obama and waited a few days to collect my thoughts and do my homework before responding.Special thanks to fellow blogger ChuckH in giving me a [handy list of reactions] for me to pick and choose from. It appears that EMC marketing machine feels it is acceptable for their own folks to claim that EMC is doing something first, or that others are catching up to EMC, but when other vendors do likewise, then that is just pathetic or incoherent. Here are a few reactions already from fellow bloggers:
This was a major announcement for EMC, addressing many of the problems, flaws and weaknesses of the earlier DMX-3 and DMX-4 deliverables. Here's my read on this:
Now you can have as many FCP ports (128) as an IBM System Storage DS8300, although the maximum number of FICON ports is still short, and no mention of ESCON support. The Ethernet ports appear to be 1Gb, not the new 10GbE you might expect.
Support for System z mainframe
V-Max adds some new support to catch up with the DS8000, like Extended Address Volumes (EAV). EMC is still not quite there yet. IBM DS8000 continues to be the best, most feature-rich storage option if you have System z mainframe servers.
Both the IBM DS8000 and HDS USP-V beat the DMX-4 in performance, and in some cases the DMX-4 even lost to the IBM XIV, so EMC had to do something about it. EMC chooses not to participate in industry-standard performance benchmarks like those from the [Storage Performance Council], which limits them to vague comparisons against older EMC gear. I'll give EMC engineers the benefit of the doubt and say that now V-Max is now "comparably as fast as HDS and IBM offerings".
Getting "V" in the name
The "V" appears to be for the roman number five, not to be confused with external heterogeneous storage virtualization that HDS USP-V and IBM SVC provide. There is no mention of synergy with EMC's failed "Invista" product, and I see no support for attaching other vendors disk to the back of this thing.
Switch to Intel processor
Apple switched its computers from PowerPC to Intel-based, and now EMC follows in the same path. There are some custom ASICs still in V-Max, so it is not as pure as IBM's offerings.
Modular, XIV-like Scale-out Architecture
Actually, the packaging appears to follow the familiar system bays and storage bays of the DMX-4 and DMX-4 950 models, but architecturally offers XIV-like attachment across a common switch network between "engines", EMC's term for interface modules.
Non-disruptive data migration
IBM's SoFS, DR550 and GMAS have this already, as does as anything connected behind an IBM SAN Volume Controller.
A long time ago, IBM used to have midrange disk storage systems called "FAStT" which stood for Fibre Array Storage Technology, so this might have given EMC the idea for their "Fully Automated Storage Tiering" acronym. The concept appears similar to what IBM introduced back in 2007 for the Scale-Out-File Services [SofS] which not only provides policy-based placement, movement and expiration on different disk tiers, includes tape tiers as well for a complete solution. I don't see anything in the V-Max announcement that it will support tape anytime soon.
And what ever happend to EMC's Atmos? Wasn't that supposed to be EMC's new direction in storage?
Zero-data loss Three-site replication
IBM already calls this Metro/Global Mirror for its IBM DS8000 series, but EMC chose to call it SRDF/EDP for Extended Distance Protection.
Ease of Use
The most significant part of the announcement is that EMC is finally focusing on ease-of-use.In addition to reducing the requirement for "Bin File" modifications, this box has a redesigned user interface to focus on usability issues. For past DMX models, EMC customers had to either hire EMC to do tasks for them that were just to difficult otherwise, or buy expensive software like their EMC Control Center to manage. EMC willcontinue to sell DMX-4 boxes for a while, as they are probably supply-constrained on the V-Max side, but I doubt they will retro-fit these new features back to DMX-3 and DMX-4.
When IBM announced its acquisition of XIV over a year ago now, customers were knocking down our doors to get one. This caught two particular groups looking like a [deer in headlights]:
EMC Symmetrix sales force: Some of the smarter ones left EMC to go sell IBM XIV, leaving EMC short-handed and having to announce they [were hiring during their layoffs]. Obviously, a few of the smart ones stayed behind, to convince their management to build something like the V-Max.
IBM DS8000 sales force: If clients are not happy with their existing EMC Symmetrix, why don't they just buy an IBM DS8000 instead? What does XIV have that DS8000 doesn't?
Let me contrast this with the situation Microsoft Windows is currently facing.
I am often asked by friends to help them pick out laptops and personal computers. I use Linux, Windows and MacOS, so have personal experience with all three operating systems.
Linux is cheaper, offers the power-user the most options for supporting older, less-powerfulequipment, but I wouldn't have my Mom use it. While distributions like Ubuntu are makinggreat strides, it is just too difficult for some people.
MacOS is nice, I like it, it works out of the box with little or no customization and an intuitive interface. However, some of my friends don't make IBM-level salaries, and have to watch their budget.
In their "I'm a PC" campaign, Microsoft is fighting both fronts. Let's examine two commercials:
In the first commercial, a young eight-year-old puts together a video from pictures oftoy animals and some background music.The message: "Windows is easier to use than Linux!" If they really wanted to send this message, they should have shown senior citizens instead.
In the second commercial, a young college student is asked to find a laptop with 17 inchscreen, and a variety of other qualifications, for under $1000 US dollars. The only modelat the Apple store below this price had a 13 inch screen, but she finds a Windows-based system that had this size screen and met all the other qualifications. The message: "Windows-based hardware from a variety of competitors are less expensive than hardware from Apple!"
Both Microsoft and Apple charge a premium for ease-of-use.In the storage world, things are completely opposite. Vendors don't charge a premium forease-of-use. In fact, some of the easiest to use are also the least expensive.
If you just have Windows and Linux, you can get some entry level system likethe IBM DS3000 series, only a few features, and can be set up in six simple steps.
Next, if you have a more interesting mix of operating systems, Linux, Windows and some flavorsof UNIX like IBM AIX, HP-UX or Sun Solaris, then you might want the features and functionsof more pricier midrange offerings. More options means that configuration and deploymentis more difficult, however.
Finally, if you are serious Fortune 500 company, running your mission critical applications on System z or System i centralized systems in a big data center, that you might be willing to pay top dollar for the most feature-rich offerings of an Enterprise-class machine.Thankfully you have an army of highly-trained staff to handle the highest levels of complexity.
IBM's DS8000, HDS USP-V and EMC's Symmetrix are the key players in the Enterprise-classspace. They tried to be ["all things to all people"], er.. perhaps all things to allplatforms. All of the features and functions came at a price, not just in dollars, butin complexity and difficulty. You needed highly skilled storage admins using expensive storage management software, or be willing to hirethe storage vendor's premium services to get the job done.
IBM recognized this trend early. IBM's SVC, N series and now XIV all offer ease-of-use withenterprise-class features and functions, at lower total cost of ownership than traditional enterprise-class systems. IBM is not the only one, of course, as smaller storage start-ups like 3PAR,Pillar Data Systems, Compellent, and to some extent Dell's EqualLogic all recognized thisand developed clever offerings as well.
While IBM's XIV may not have been the first to introduce a modular, scale-out architectureusing commodity parts managed by sophisticated ease-of-use interfaces, its success might have been the kick-in-the-butt EMC needed to follow the rest of the industry in this direction.
Continuing my week's theme on the XO laptop from the One Laptop Per Child [OLPC] project, I have been amused watching the OLPC forum discussion on the choiceof browser options available.
The built-in browser is simple but functional. It is full screen,with back, forward, and bookmark buttons, and an entry field forthe URL. This browser is fully integrated with the Sugar platform,files downloaded will appear in the journal. Download an Activity*.xo file, for example, and you can install it from the Journal.If you want to upload a file, click BROWSE on the website, and theJournal will pop up to choose files from.
Out of the box, the XO supports a minimal Flash that can handlesome Flash-based games but not YouTube videos, and does not supportJava.
The good folks of Opera have built a special edition for the XO laptop.However, some settings need to be changed to make the fonts large enoughto read.
Opera can be run as a Sugar activity, but this just launches a mothertask, which in turn launches a daughter task that actually runs thebrowser. This means that Home View will have two icons. The mothertask has an the Opera icon, but click on it and you get a grey screen.The daughter task appears as a grey circle, click on it and you get thebrowser screen. Alt-Tab will rotate through the Activities, so thegrey screen of the mother task is part of the rotation.
Although Opera has one foot on the Sugar platform, and one foot off,the lack of integration means poor interaction with the journal. The use of Opera is correctly registered. However, downloadingfiles requires a working knowledge of subdirectories, and uploading anythingrequires knowing what it is called, and where it is located. Not obviousfor many of the items created by Sugar applications.
The XO laptop is based on Redhat Fedora distribution, so I downloadedthe Firefox RPM package and installed this. To run, you need to startthe Terminal Activity, and then at the cursor type firefox.Journal only registers that the Terminal activity was used, but not anythingelse.
Since I run Firefox 2.0 on Windows XP, OS X and Linux, I am very familiarwith this browser, and it works as expected. Like Opera, there are shortcut keys, tabs for multiple pages, and optionsto add Java and Flash player. I was able to install add-onsfor Del.icio.us and FireFTP, and they worked as expected. Having accessto FTP sites will make development on the XO much easier.Again all files are uploaded/downloaded to directories, so some workingknowledge of where files are placed is required.
The fonts in Firefox did not expand/shrink as nicely as they had in Opera.Be careful not to select "View->
To close, you have to select File->Quit from the browser window, whichbrings you back to the Terminal activity, which you can then shutdown with Ctrl-Esc.
For now, I will keep all three and continue to evaluate them.I saw a few opportunities for improvement:
The Opera and Terminal icons are not on the first screen.You have to hit the right arrow to get to the "overflow" set of icons. Re-ordering the icons is simply a matter of editing the following file with "vi"(my first few lines I use are shown below):
Put the activities in the order you want. Any activity not listed willappear after these.
It might be possible to create a modified Terminal activity thatinvoked Firefox directly, to eliminate having to type it in each time.
Several people have expressed interest in a browser that runs entirely withthe Xo laptop folded over in eBook/Game mode, such that thekeyboard is completely covered up, exposing only the up-left-right-down arrowsand the Circle/Square/X/Check buttons.
Change the "News Reader" to invoke Bloglines instead. This might be yetanother modified Terminal activity, but borrow the icon from News.
Well, if you have further thoughts on these browsers, enter a comment below.
I hope everyone had a nice Winter break. For my birthday last month, my good friends at [StarTech.com] sent me a nice [double-headed USB combo cable] that has both Micro-USB and Mini-USB connectors. I am always looking to reduce the number of cables I take with me on trips, and this one is perfect, as I have a Samsung 4G smart phone that uses the Micro-USB connector, and a Canon PowerShot digital camera that uses the Mini-USB connector.
(FTC Disclosure: The U.S. Federal Trade Commission may consider this a "celebrity endorsement" for StarTech's product. I have used the cable and it works as expected. My review is based on my own experience using the cable, and information publicly available. IBM and StarTech are independent companies. Aside from giving me this nice cable at no cost, I have not received any payment from StarTech or any other third party to mention them or their product on this blog, I am not affiliated with StarTech in any way, nor do I have any financial interest in their company.)
When the [Universal Serial Bus] standard first came out in the mid-1990s, my colleagues and I were all excited that this will finally put an end to all the proprietary plugs and cables that each manufacturer seemed to waste their time re-inventing the wheel with yet another cable connector. For the most part, USB has simplified this, and the USB cable can be used for both data transfer and for power charging.
Today, there are many alternatives to using a cable for data transfer, such as Wi-Fi and Bluetooth, but people are finding that their smart phones and other devices run out of juice way too often. At various conferences, I have seen several people panic looking for an electrical outlet to charge their device, and a few brazen enough to ask other attendees, "Can I plug my phone into your laptop?"
(Caution: Be careful allowing strangers to plug their device into your USB port, as this can provide data transfer in addition to power charging, spreading viruses or other malicious intent. On my Lenovo Thinkpad T410, one of the USB ports is colored yellow and is always powered on, even when my laptop is in suspend or hibernation mode. This would be a safe way to allow someone to charge off your power without concern for data transfer in either direction.)
Recently, I have flown on airplanes where each seat had a USB charging port, ideal if you want to listen to music or watch a video on your device. I have also driven a rental carthat had USB charging ports in addition to the traditional cigarette lighter option, especially useful if you need to make an emergency phone call at the side of the road, or if you are using the GPS navigation feature to find your way. These are both a good step in the right direction!
Carrying one cable instead of two might not seem like much of a big deal, but if you think about it, complexity in the IT industry is all about the number of cables admins have to deal with. The push from 1GbE to 10GbE can help reduce the number of cables. Converged Enhanced Ethernet (CEE) takes it one step further, allowing NFS, CIFS, iSCSI and FCoE to all flow over a single cable. This can greatly reduce complexity in your IT environment.
If you are interested in reducing the complexity in your IT environment, contact your local IBM Business Partner or sales representative.
This week I am in Chicago for the IBM Storage and Storage Networking Symposium, which coincides with the System x and BladeCenter Technical Conference. This allows the 800 attendees to attend both storage or server presentations at their convenience. There were hundreds of sessions, over 20 time slots, so for each time slot, you have 15 or so topics to choose from.Mike Kuhn kicked off the series of keynote sessions. Here's my quick recap of each one:
Curtis Tearte, General Manager, IBM System Storage
Curtis replaced Andy Monshaw as General Manager for IBM System Storage. His presentation focused on how storage fits into IBM's Dynamic Infrastructure strategy. Some interesting points:
a billion camera-enabled cell phones were sold in 2007, compared to 450 million in 2006.
IBM expects that there will be 2 billion internet users by 2011, as well as trillions of "things".
In the US, there were 2.2 million medical pharmacy dispensing errors resulting for handwritten prescriptions.
Time wasted looking for parking spaces in Los Angeles consumed 47,000 gallons of gasoline, and generated 730 tons of carbon dioxide.
In the US, 4.2 billion hours are lost, and 2.9 billion gallons of gas consumed, due to traffic congestion.
Over the past decade, servers went from 8 watts to 100 watts per $1000 US dollars.
Data growth appears immune to the economic recession. The digital footprint per person is expected to grow from 1TB today to over 15TB by 2020.
10 hours of YouTube videos are uploaded every minute.
Bank of China manages 380 million bank accounts, processing over 10,000 transactions per second.
At the end of the session, Curtis transitioned from demonstrating his knowledge and passion of storage to his knowledge and passion in his favorite sport: baseball. Chicago is home to both the Cubs and the White Sox.
Roland Hagan, Vice President Business Line Executive, System x
IBM sets the infrastructure agenda for the entire industry. The Dynamic Infrastructure initiative is not just IT, but a complete end-to-end view across all of the infrastructures in play, including transportation, manufacturing, services and facilities.Companies spent over $60 billion US dollars on servers last year. Of these, 53 percent for x86-based servers, 9 percent for Itanium-based, 26 percent for RISC-based (POWER6, SPARC, etc.), and 11 percent mainframe. Theeconomic downturn has impacted revenues, but the percentages continue about the same.
The dominant deployment model remains one application per server. As a result, power, cooling and management costs have grown tremendously. There are system admins opposed to consolidating server images with VMware, Hyper-V, Xen or other server virtualizaition technologies. Roland referred to these admins as "server huggers".To help clients adopt cloud computing technologies, IBM introduced [Cloudburst] appliances. IBM plans to offer specialized versions for developers, for service providers, and for enterprises.
IBM's Enterprise-X Architecture is what differentiates IBM's x86-based servers from all the competitors, surrounding Intel and AMD processors with technology that provides distinct advantages. For example, to support server virtualization, IBM's eX4 provides support for more memory, which often is more critical than CPU resources when deploying large number of guest OS images. IBM System x servers have an integrated management module (IMM) and was the first to change over from BIOS to the new Unified Extensible Firmware Interface [UEFI] standard.
IBM servers offer double the performance, consume half the power, and cost a third less to manage, than comparably priced servers from competitors. Of the top 20 more energy efficient server deployments, 19 are from IBM. Roland cited customer reference SciNet, a 4000-server supercomputer with 30,000 cores based on IBM [iDataPlex] servers. At 350 TeraFLOPs it is ranked #16 fastest supercomputer in the world, and #1 in Canada. With apower usage effectiveness (PUE) less than 1.2, it also is very energy efficient. This means that for every 12 watts of electricity going in to the data center, 10 watts are used for servers, storage and networking gear, andonly 2 watts used for power and cooling. Traditional data centers have PUE around 2.5, consuming 25 watts total for every 10 watts used by servers, storage and networking gear.
Clod Barrera, Distinguished Engineer, Chief Technical Strategist for IBM System Storage
Clod presented trends and directions for disk and tape technology, disk and tape systems, and the direction towards cloud computing.
This is a reasonable question. Since Invista 2.0 came out months ago in August, and Invista 2.1 is rumored to be out by end of this month, why put out a press release now, rather than just wait a few weeks? Thesignificant part of this announcement was that EMC finally has their first customer reference.To be fair, getting a customer to agree to be a reference is difficult for any vendor. Some non-profitsand government agencies have rules against it, and some corporations just don't want to be bothered byjournalists, or take phone calls from other prospective customers. I suspect EMC wanted to put the good folks from Purdue University in front of the cameras and microphones before they:
In Moore's terminology, Purdue University would be a "technology enthusiast", interested in exploring the technologyof the EMC Invista. Universities by their very nature often see themselves as early adopters, willing to take big risks in hopes to reap big rewards. The chasm happens later, when there are a lot of early adopters, all willing to be reference accounts. The mainstream market--shown here as pragmatists, conservatives, and skeptics-- are unwillingto accept reference claims from early adopters, searching instead for moderate gains from minimal risks. They prefer references from customers that are similar in size and industry. Whether a vendor can get a product to cross this chasm is the focus of the book.
Why "SAN" virtualization?
Technically, Invista is "storage" virtualization, not "SAN" virtualization. Virtualizationis any technology that makes one set of resources look and feel like a different setof resources, preferably with more desirable characteristics. You can virtualizeservers, SANs, and storage resources.
Virtual SAN (VSAN) technology, supported bythe Cisco MDS 9500 Series Multilayer Director Switch, partitions a single physical SAN into multipleVSANs, allowing different business functions and requirements to share a common physical infrastructure.
How does Invista advance Cisco's VSAN functionality? It doesn't, but that doesn't makethe title a falsehood, or the press release by association full of lies.If you read the entire press release, EMCcorrectly states that Invista is "storage" virtualization. Some storagevirtualization products, like EMC Invista and IBM System Storage SAN Volume Controller (SVC), require a SAN as a platform for which to perform their magic.Marketing people might use the term "SAN" torefer not just the network gear that provides the plumbing, but also to include the storage devices that are attached to the SAN. In that light, theuse of "SAN virtualization" can be understood in the title.
More importantly, it appears that EMC no longer requires that you purchase new SAN equipment from themwith Invista. When the Invista first came out, it cost over a quarter-million US dollars to cover thecost of the intelligent switches, but with the price drop to $100K, I imagine this means theyassume everyone has an appropriately-supported intelligent switch already deployed.
Why this architecture?
In his post [Storage Virtualization and Invista 2.0], EMC blogger ChuckH does a fair job explaining why EMC went in this direction for Invista, and how it is different thanother storage virtualization products.
Most storage virtualization products are cache-based. The world's first disk storagevirtualization product, the IBM 3850 Mass Storage System, introduced in 1974, and thefirst tape virtualization product, the IBM 3494 Virtual tape Server, introduced in 1997, bothused disk cache in front of tape storage. Later virtualization products, like IBM SVC and HDS USP-V, use DRAM memory cache in front of disk storage, but the concept is the same.People are comfortable with cache-based solutions, because the technology is matureand well proven in the marketplace, and excited and delighted that these can offer the following features in a mixed heterogeneous disk environment:
instantaneous point-in-time copy
None of these features are provided by Invista, as there is no cache in the switch. Instead,Invista is a "packet cracker"; it cracks open each FCP packet, inspects and modifies the contents, then passes theFCP packet along to the appropriate storage device. This process slows down each read andwrite by some amount, perhaps 20 microseconds. The disadvantage of slowing down every readand write is offset by having other benefits, like non-disruptive data migration.
To compensate for Invista's inability to provide these features,EMC offers a second solution called EMC RecoverPoint, which is an in-band cache-based appliancesimilar in design to SVC, but maps all virtual disks one-to-one to physical disks. It offersremote distance asynchronous mirroring between heterogeneous devices.EMC supports RecoverPoint in front of Invista, but if you are considering buying bothto get the combined set of features, you might as well buy an IBM SVC or HDS USP-V instead,in one system, rather than two, which is much less complicated. IBM SVC and HDS USP-Vhave both "crossed the chasm" having sold thousands of units to every type and size of customer.
Hopefully, this answers the questions you might have about EMC Invista.
On his blog post on preparation, Seth Godin mentioned an appropriate Swedish saying:
There is no bad weather, just bad clothing.
Appropriate because it snowed here in Tucson, Arizona on Sunday evening, leaving many of us here figuring out how to drive through the stuff on Monday. In my entire lifetime, I have only witness snow down in the Tucson valley a handful of times. It got me thinking about coats, and the wonderful schemes for coat check rooms, as an analogy for data access. A lot of people ask me to compare and contrast one technology from another, say block-level virtualization from content-addressable storage, and so on, and I always try to find a good analogy to help explain things.
Let's start with the setting. It is snowing outside and people are wearing coats. When they come inside, they check their coats at a coat check room, a large room with rows and rows of racks with hangers. A coat check attendant takes your coat and puts it on a hanger, and gives you a ticket or other identifier that will allow you to retrieve your coat later. The ticket must have sufficient information to retrieve the coat quickly, rather than searching rows and rows of hangers for it.
Block-based disk storage
You walk to the coat-check desk, tell the attendant to hang your coat on a specific hanger, say hanger number 387. When you come back, you ask for the coat on hanger 387. The coat-check attendant knows exactly where hanger 387 is, and is able to retrieve it quickly. Most disk systems use this approach, including IBM SAN Volume Controller and DS family of disk systems.
Name-based disk storage
You walk to the coat-check desk, tell the person the name that you want to call your coat. An empty hanger is located, and a list of coat names, with their associated hanger number, is then kept. Upon return, you ask for your coat by name, and the coat-check attendant looks up the hanger number to match, and retrieves your coat. This is the scheme used by the IBM System Storage DR550, N series for NAS storage, and the IBM Healthcare and Life Sciences Grid Medical Archive Solution (GMAS).
Content-addressable storage (CAS)
You walk to the coat-check desk and hand them your coat. The attendant weighs your coat, checks the brand, the size, the number of buttons and zippers, types it all in, and the computer spits out a "hash code" from 1 to 99999. An empty hanger is found, and the hash code is associated to the hanger number. Upon return, you provide the hash code you were given, and the coat-check attendant looks up the hanger number to match, and retrieves your coat.This is the scheme used for some non-erasable, non-rewriteable storage, such as the EMC Centera.
IBM invented hash codes in 1953 as a way to speed up searches. For example, if you want to look up a word in the dictionary, knowing the first letter of the word makes it much quicker, because you can thumb directly to that section. A hash code was intended to give a more even distribution, so that if a million words are stored in a "hash code dictionary" then you would calculate the hash code, then look up only that section of words associated with that specific hash code number.
A problem arises when you generate "hash codes" for storage. It is possible for two different pieces of data to resolve to the same hash code. When an application tries to write a piece of data, and it resolves to a hash code that already exists, that is called a collision. One response is to either compare the incoming data to the data that is already stored, confirm they are identical, but that can be time consuming. The other response is to just assume they are identical, and reject the secondary copy, a process often referred to as "de-duplication".
What's the chance of getting a collision for data that is really different? Let's take for example the famousBirthday paradox. Suppose the coat check room assigned the hanger based on your birthday (month and day). How may coats before you run the risk of having two people turn in coats with the same birthday? After only 23 people, the likelihood is 50%. At 60 people, it goes up to 99%.
For this reason, IBM does not offer content-addressable storage. For non-erasable, non-rewriteable storage, the IBM System Storage DR550 requires the application to give each object a name, and that name is then used to storage the data, eliminating the possibility that data might accidently be thrown away.
Wrapping up my coverage of the Data Center Conference 2009, the week ends with a celebration. This year we had six "Hospitality Suites" sponsored by various different vendors. Each suite has its own theme, decorations and entertainment. The first suite was VMware's "Cloud 9 Ultra Lounge" which offered blue cotton candy martinis. IBM is the leading reseller of VMware.
When the red martini liquid was poured on top of the blue cotton candy, the result was a nasty muddish brown grey color. The guy on the left chose to get the martini without the blue cotton candy. We joked that this is perhaps a good metaphor for cloud computing in general. It looks good on paper, until you actually put it all together and realize it does not look as blue and puffy as you were expecting. However, it tasted good!
Next suite was sponsored by Cisco, one of IBM's storage networking partners. Cisco also decorated in blue, as the guy Jake in the middle demonstrates.
Next suite was sponsored by Brocade, our supplier for IBM-branded networking gear. They went with a red-and-black color scheme. Sadly, many of my pictures inside involved straight jackets and unicycles, so not appropriate for this blog. However, it was easy to remember that they were talking about their "extraordinary networks". Makes you want to help out Brocade by contacting your nearest IBM storage sales rep and buy yourself a SAN768B or two.
Somewhere along the way, we picked up Hawaiian leis at the "Margaritaville" Hospitality Suite, compliments of sponsor APC by Schneider Electric. We had the best "Filet Mignon" appetizers at "Club Dedupe" by our competitor DataDomain, and some fun with my friends over at Computer Associates' "Top Gun" suite. Pictured at right are Paula Koziol with Christian Barrera from Argentina. A good time was had by all.
Continuing my coverage of the 30th annual [Data Center Conference]. Here is a recap of the Monday afternoon sessions:
IBM Watson and your Data Center
Steve Sams, IBM VP of Site and Facilities Services, cleverly used IBM Watson as a way to explain how analytics can be used to help manage your data center. Sadly, most of the people at my table missed the connection between IBM Watson and Analytics. How does answering a single trivia question in under three seconds relate to the ongoing operations of a data center? If you were similarly confused, take a peak at my series of IBM Watson blog posts:
The analyst who presented this topic was probably the fastest-speaking Texan I have met. He covered various aspects of Cloud Computing that people need to consider. Why hasn't Cloud taken off sooner? The analyst feels that Cloud Computing wasn't ready for us, and we weren't ready for Cloud Computing. The fundamentals of Cloud Computing have not changed, but we as a society have. Now that many end users are comfortable consuming public cloud resources, from Facebook to Twitter to Gmail, they are beginning to ask for similar from their corporate IT.
Legal issues - see this hour-long video, [Cloud Law & Order], which discusses legal issues related to Cloud Computing.
Employee staffing - need to re-tool and re-train IT employees to start thinking of their IT as a service provider internally.
Hybrid Cloud - rather than struggle choosing between private and public cloud methodologies, consider a combination of both.
University of Rochester Medical Center (URMC) Cracks Code on Data Growth
Often times, the hour is split, 30 minutes of the sponsor talking about various products, followed by 30 minutes of the client giving a user experience. Instead, I decided to let the client speak for 45 minutes, and then I moderated the Q&A for the remaining 15 minutes. This revised format seemed to be well-received!
University of Rochester is in New York, about 60 miles east of Buffalo, and 90 miles from Toronto across Lake Ontario. Six years ago, Rick Haverty joined URMC as the Director of Infrastructure services, managing 130 of the 300 IT personnel at the Medical Center. I met Rick back in May, when he presented at the IBM [Storage Innovation Executive Summit] in New York City.
URMC has DS8000, DS5000, XIV, SONAS, Storwize V7000 and is in the process of deploying Storwize V7000 Unified. He presented how he has used these for continuous operations and high availability, while controlling storage growth and costs.
The Q&A was lively, focusing on how his team manages 1PB of disk storage with just four storage administrators, his choice of a "Vendor Neutral Archive" (VNA), and his experiences with integration.
This was a great afternoon, and I was glad to get all my speaking gigs done early in the week. I would like to thank Rick Haverty of URMC for doing a great job presenting this afternoon!
This week is IBM Pulse2012 conference in Las Vegas. I am not there, for medial reasons this time. While my colleagues will be spending this week sipping Margaritas and enjoying the music in between inspiring technical sessions, I will be flat on my back, getting all my nutrients from a tube connected to my arm, listening to the hospital equivalent of [Muzak].
"IBM Pulse 2012 ‘s opening keynote talked about the realities of cloud as a delivery model – without the ‘private-‘, or the ‘public-‘, or even the quotes or capitalization of “The Cloud.” It was IBM’s perspective on what IBM knows better than most, how to deliver enterprise IT services that map to strategic business goals."
"In contrast to talking about ‘data-center/cloud’ stuff and then later about ‘consumerization-of-IT’ stuff , IBM’s core message was how mobility was in many ways driving cloud evolution."
"...cloud-based delivery was ‘more than just virtualization’"
"...the US Dept of Labor stating that jobs related to technology are forecast to be among the fastest growing segment thru 2018."
Hopefully, this post will hold you over until I regain consciousness.
IBM announced that it will offer [three free months of IBM Smart Business Cloud] computing and storage services to government agencies, charitable non-profit organizations, and other organizations involved with reconstruction resulting from the earthquakes and tsunami in Japan and the northern Pacific region.
With traditional communications down, and many data centers incapacitated, Cloud Computing can be a great way to resume operations. According to the announcement, organizations can submit their requests now until April 30, and the program will run until July 31, 2011. Options include:
Virtual machine images running 32-bit and 64-bit versions of Linux or Windows.
60GB to 2 TB of disk storage per instance.
Options for various IBM middleware (DB2, Informix, Lotus, and WebSphere)
Rational Application Lifecycle Management and Tivoli Monitoring software
The offer also includes [LotusLive] Software-as-a-Service (SaaS) for email and online collaboration. For more about LotusLive, see this [Red Paper].
"This week, IBM is launching a companywide effort to build the digital eminence of all IBMers. The goal is to arm you with the tools and knowledge to effectively use emerging technologies -- such as social, mobile, and cloud computing -- for strategic advantage."
This is how Rod Adkins, IBM Senior VP of Systems Technology Group, and my sixth-line manager, starts a memo to declare April "Digital IBMer awareness month". I am not sure if this is just for this April, or every April going forward. Included with this is a set of ten guidelines to improve CyberSecurity:
In honor of this, I will be spending the next two weeks traveling through Europe. Instead of bringing a large suitcase and my laptop, I have decided instead to only take:
The clothes I am wearing on the plane
A heavy jacket with lots of pockets
A backpack with 15 pounds of clothes
A hipsack with my smartphone, digital camera, MP3 player and all the related adapters, chargers and cables
My smartphone uses a GSM chip, so I should be able to get a European SIM when I arrive. I have not booked any hotels, tours, or transportation. Instead, I will rely on social media and cloud computing to take care of things on a daily basis.
(Why only 15 pounds of clothing? I just had major surgery two weeks ago, and my doctor advised me not to lift more than 15 pounds for the next six weeks!)
I plan to have a series of blog posts documenting what I learn from this trip. For those who want to follow along, I will be tweeting from @az990tony. You do not need a Twitter account to read my tweets. You can read them directly from [http://twitter.com/#!/az990tony].
I can't remember the last time I have gone this long without the comforts of my laptop or desktop, so it will be interesting how it works out!
I welcome HDS into the "Super High-End" club. Those who follow my blog might remember thatI suggested that analysts like IDC that use "Entry Level", "Midrange" and "Enterprise" as categoriesmay need a New Category: Super High End.
I was not surprised to see EMC, who now drops further down in perception, dispute HDS's recent SPC-1 benchmarks.Fellow blogger EMC's BarryB posted on his Storage Anarchist blog [IBM vs. Hitachi] thatpoints out that IBM's SAN Volume Controller (SVC) is still much faster, and less expensive, than USP-V.
So, just in case you haven't seen all the press releases, here is a quick recap on the results:IBM SVC 4.2 is still in first place, then HDS USP-V, then IBM System Storage DS8300. Just for comparison, I includeour IBM System Storage DS4800 midrange disk results, so you can appreciate the difference between midrange and high-end.There are other products from other vendors, I just point out a few from IBM and HDS here in this graph.
******************************************************************** 272,505 IOPS - IBM SVC 4.2 ************************************************** 200,245 IOPS - HDS USP-V ******************************* 123,033 IOPS - IBM DS8300 *********** 45,014 IBM DS4800
HDS tried to come up with a phrase "Enterprise Storage System" for comparison that would leave the SVC 4.2 out.Given that the SVC has five nines (99.999%) availability, has non-disruptive upgrade and firmware update capability, has more than two processors typical of midrange products, and can connect to mainframes via z/VM, z/VSE andLinux on System z operating systems, there is no reason to pretend SVC isn't Enterprise-class.
The irony now is that EMC now looks very lonely being one of the last remaining major storage vendors not to participate in standardized benchmarks that help customers make purchase decisions, as mentioned both by IBM's BarryW: I guess that only leaves EMC, as well as HDS's Claus Mikkelsen: Olympics of Storage.
Earlier this year, EMC's Chuck Hollis opined[Storage Scorecard]that the EMC DMX and HDS TagmaStore USP were high-endboxes, which I would speculate both of these would fall somewhere between DS4800 and DS8300 on the graph above.If that is the case, it is impressive that HDS was able to re-engineer their USP-V to be 2-3x faster thanits predecessor, the USP.
Not all workloads are the same, and your mileage may vary. While I can't speak to HDS, the folks over atEMC have assured me, in writingcomments on this blog, that there is nothing preventing their customers from publishingtheir own performance comparisons between EMC and non-EMC equipment. I would encourage every customer to do this, between IBM and HDS, HDS and EMC, and between IBM and EMC, to help shed even more light on this area.In fact, you can even run your own SPC benchmarks to see how your own environment compares to the ones published.
Of course, performance is just one attribute on which to choose a storage vendor, and to choose specific products,models or features. For more information about Storage Performance Council and the SPC-1 and SPC-2 benchmarks,see my week-long series on SPC benchmarks, which are listed in reverse chronological order.
Go to the official Storage Performance Council website to read the details of the SPC-1 results.
With all the announcements we had in June, it is easy for some of the more subtle enhancements to get overlooked. While I was at Orlando for the IBM Edge conference, I was able to blog about some of the key featured announcements. Then, later, when I got back from Orlando to Tucson, I was able to then blog about [More IBM Storage Announcements]. For IBM's Scale-Out Network Attach Storage (SONAS), I had simply:
"SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports Gateway configurations that have the storage nodes connected to XIV or Storwize V7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients."
In my defense, IBM numbers its software releasees with version.release.modification, so 1.3.2 is Version 1, Release 3, Modification 2. Generally, modification announcements don't get much attention. The big announcement for v1.3.0 of SONAS happened last October, see my blog post [October 2011 Announcements - Part I] or
the nice summary post [IBM Scale-out Network Attached Storage 1.3.0] from fellow blogger Roger Luethy.
Here is a diagram showing the three configurations of SONAS.
I have covered the SONAS Appliance model in depth in previous blogs, with options for fast and slow disk speeds, choice of RAID protection levels, a collection of enterprise-class software features provided at no additional charge, and interfaces to support a variety of third party backup and anti-virus checking software.
The basics haven't changed. The SONAS appliance consists of 2 to 32 interface nodes, 2 to 60 storage nodes, and up to 7,200 disk drives. The maximum configuration takes up 17 frames and holds 21.6PB of raw disk capacity, which is about 17PB usable space when RAID6 is configured. An interface nodes has one or two hex-core processors with up to 144GB of RAM to offer up to 3.5GB/sec performance each. This makes IBM SONAS the fastest performing and most scalable disk system in IBM's System Storage product line.
I thought I would go a bit deeper on the gateway models. These models support up to ten storage nodes, organized in pairs. The key difference is that instead of internal disk controllers, the storage nodes connect to external disk systems. There is enough space in the base SONAS rack to hold up to six interface nodes, or you can add a second rack if you need more interface nodes for increased performance.
SONAS with XIV gateway
XIV offers a clever approach to storage that allows for incredibly fast access to data on relatively slow 7200 RPM drives. By scattering data across all drives and taking advantage of parallel processing, rebuild times for a failed 3TB drive are less than 75 minutes. Compare that to typical rebuild times for 3TB drives that could take as much as 9-10 hours under active I/O loads!
In the configuration, each pair of storage nodes can connect to external SAN Fabric switches that then connect to one or two XIV storage systems. How simple is that? These can be the original XIV systems that support 1TB and 2TB drives, or the new XIV Gen3 systems that support 400GB Solid-state drives (SSD) and 3TB spinning disk drives. In both cases, you can acquire additional storage capacity as little as 12 drives at a time (one XIV module holds 12 drives).
The maximum configuration of ten XIV boxes could hold 1,800 drives. At 3TB drive per drive, that would be 2.4PB usable capacity.
The SONAS with XIV gateway does not require the XIV devices to be dedicated for SONAS purposes. Rather, you can assign some XIV storage space for the SONAS, and the rest is available for other servers. In this manner, SONAS just looks like another set of Linux-based servers to the XIV storage system. This in effect gives you "Unified Storage", with a full complement of NAS protocols from the SONAS side (NFS, CIFS, FTP, HTTPS, SCP) as well as block-based protocols directly from the XIV (FCP, iSCSI).
SONAS with Storwize V7000 gateway
The other gateway offering is the SONAS with Storwize V7000. Like the SONAS with XIV gateway model, you connect a pair of SONAS storage nodes to 1 or 2 Storwize V7000 disk systems. However, you do not need a SAN Fabric switch in between. You can instead connect the SONAS storage nodes directly to the Storwize V7000 control enclosures.
To acquire additional storage capacity, you can purchase a single drive at a time. That's right. Not 12 drives, or 60 drives, at a time, but one at a time. The Storwize V7000 supports a wide range of SSD, SAS and NL-SAS drives at different sizes, speeds and capacities. The drives can be configured into various RAID protection levels: RAID 0, 1, 3, 5, 6 and 10.
Each Storwize V7000 control enclosure can have up to nine expansion drawers. If you choose the 2.5-inch 24-bay models, you can have up to 480 drives per storage node pair, for a total of 2,400 drives. If you choose the 3.5-inch 12-bay models, you can have up to 240 drives per node pair, 1,200 drives total. At 3TB per drive, this could be 3.6PB of raw capacity. The usable PB would depend on which RAID level you selected. Of course, you don't have to limit yourself all to one size or the other. Feel free to mix 2.5-inch and 3.5-inch drawers to provide different storage pool capabilities.
All three SONAS configurations support Active Cloud Engine. This is a collection of features that differentiate SONAS from the other scale-out NAS wannabees in the marketplace:
Policy-driven Data Placement -- Different files can be directed to different storage pools. You no longer have to associate certain file systems to certain storage technologies.
High-speed Scan Engine -- SONAS can scan 10 million files per minute, per node. These scans can be used to drive data migration, backups, expirations, or replications, for example. It is over 100 times faster than traditional walk-the-directory-tree approaches employed by other NAS solutions.
Policy-driven Migration -- You can migrate files from one storage pool to another, based on age, days since last reference, size, and other criteria. The files can be moved from disk to disk, or move out of SONAS and stored on external media, such as tape or a virtual tape library. A lot of data stored on NAS systems is dormant, with little or no likelihood of being looked at again. Why waste money keeping that kind of data on expensive disk? With SONAS, you can move those files to tape can save lots of money. The files are stubbed in the SONAS file system, so that an access request to a file will automatically trigger a recall to fetch the data from tape back to the SONAS system.
Policy-driven Expiration -- SONAS can help you keep your system clean, by helping you decide what files should be deleted. This is especially useful for things like logs and traces that tend to just hang around until some deletes them manually.
WAN Caching -- This allows one SONAS to act as a "Cloud Storage Gateway" for another SONAS at a remote location connected by Wide Area Network (WAN). Let's say your main data center has a large SONAS repository of files, and a small branch office has a smaller SONAS. This allows all locations to have a "Global" view of the all the interconnected SONAS systems, with a high-speed user experience for local LAN-based access to the most recent and frequently used files.
If you want to learn more, see the [IBM SONAS landing page]. Next week, I will be across the Pacific Ocean in [Taipei], to teach IBM Top Gun class to sales reps and IBM Business Partners. "Selling SONAS" will be one of the topics I will be covering!
Continuing my week's theme on travel, conferences, and Japan, I saw two items in the newsthat seem to follow a common theme.
According to the "The Daily Yomiuri", a local Japanese paper, "double happy weddings" arebecoming more and more popular in Japan. These would be called "stotgun" weddings in the US, butin Japan, couples pay extra to have a wedding between the fifth and seventh month ofpregnancy. As Dave Barry would say, I am not making this up. 27% of couples in Japan got married while or after pregnant. The logic is that they can celebrate both events with one ceremony. Many couples believe that the primary purpose of marriage is to have children, and somethat fail to have children suffer terrible anguish or divorce. Waiting untilbeing pregnant helps ensure the couple will be "successful" in this regard.
IBM acquires Softek, a software company that develops a product called Transparent Data MoverFacility (TDMF) to move mainframe data from one disk system to another, while applicationsare running. This can be used, for example, to move data from outdated disk systems to IBMdisk systems. This is not to be confused with IBM's archive and retention software partner,Princeton Softech.
Softek is the software spin-off of Fujitsu (a Japanese computer hardware manufacturer). Fora while, Fujitsu made IBM-compatible mainframe servers, but was not successful at developingits own system software, relying heavily on IBM for this. Unable to compete against IBM, it stoppedmaking mainframe servers, but continues making other kinds of hardware equipment.
With TDMF, the process of moving data is simple. The software runs on z/OS and intercepts all writes intendedfor a source volumes on the old array, and re-directs a copy to destination volumes on the new device.Systems can run with old and new equipment side by side for a few weeks, with the new devicestaying in-sync with the old. When the client is ready to cross over, the systems arepointed to the new disk, and the old disk systems are detached and removed from the sysplex.
Afraid that installing TDMF will mess with your applications? IBM Global Technology Services (GTS)is able to roll-in a separate mainframe, move the data, than disconnect it along with the old storage.
(For customers running Linux, UNIX or Windows on other platforms, IBM offers SAN Volume Controller (SVC).While SVC is not marketed as a "data migration device", per se, it does have this capability.Many clients were able to cost-justify purchase of an SVCto move data from old storage to new in similar fashion to how TDMF works on the mainframe.)
What do these stories have to do with one another, other than both relating to Japan? IBM has beenusing TDMF for years as part of a service offering to move data from one disk system to another.Since Sam Palmiasano took over in 2002, IBM has acquired 51 companies, 31 of them software companies.Often, these have been "successful" turning quickly profitable because IBM was already well familiar with the companies they acquire, in much the same way that husbandsare well familiar with their brides-to-be at a "double happy wedding".
So, welcome Softek! It looks like its time to celebrate again!
Well, it's Tuesday, in the United States at least, and you know what that means... IBM Announcements! I am actually down under in Sydney, Australia, and it is Wednesday already as I write this. I feel like a time traveler.
IBM announces their latest disk system, the [IBM System Storage DCS3700], designed for high-performance computing (HPC), business analytics, video broadcasting, and other sequential workloads. The "DCS" stands for Deep Computing Storage. IBM already has the DCS9900 for large enterprise deployments, so this smaller DCS3700 is targeted for midrange deployments.
In a compact 4U package, the DCS3700 packs dual active-active controllers and up to 60 disk drives. The controller drawer can support two additional expansion drawers, of 60 drives each in 4U drawers, for a maximum total of 180 drives in 12U of rack space. Packed with "green" 7200RPM energy-efficient 2TB drives, a system can have up to a 360TB raw capacity. The system supports RAID levels 0, 1, 3, 5, 6, and 10.
The system comes with the latest 6Gbps SAS connections for host attachment, but you can choose 8Gbps Fibre Channel Protocol (FCP) instead, allowing the DCS3700 to be managed by SVC or Storwize V7000.
While I was in Auckland, New Zealand, for the IBM Storage Optimisation Breakfast series of events, I agreed to also talk at the [Ingram Micro Showcase 2010] held there the same week. David Bird, who was scheduled to speak, was down in Christchurch taking care of his family after the big 7.1 magnitude earthquake.
The marketing team did a great job putting up a "Smarter Planet" ball up near the ceiling. It had to be "enhanced" with some extra black ink to include the outline of the islands of New Zealand.
Basically, I had 25 minutes to present "Future Storage Trends" to a packed room with standing room only. This was a shortened version of my 40-minute talk that I had been already giving at the Storage Optimisation Breakfast events. This presentation was based on three key trends:
There is a shift in the role each storage media type is going to be used for. Rising energy costs, performance and economics are causing the IT industry to re-evaluate their use of solid-state drives, spinning disk, tape cartridge, paper and analog film. IBM Easy Tier and blended disk-and-tape solutions are paving the way for these future trends.
Advancements in commuications technology and bandwidth are driving a convergence of SANs and LANs to a single Data Center Network (DCN) based on Convergence Enhanced Ethernet (CEE). IBM's top-of-rack switches and converged network adapaters (CNA) are the first step in this process.
Cloud Computing is driving new levels of standardization, automation and management that will impact the way internal IT departments will manage their own IT equipment as well. IBM's five different levels of cloud computing offerings, from private cloud to public cloud, provides every individual or company a level of service that is just right.
Here is the IBM booth. As is often the case, we get a prestigious corner booth that maximizes foot traffic to see our solutions.
While walking around, the folks at the Samsung booth notices my Samsung Galaxy S smartphone. These are not yet available in the New Zealand market, so they thought I was a Samsung employee. I explained that I am an American, and that these have been available for weeks now in the states.
The Samsung team then showed me their latest 3D television. Basically, you wear special 3D glasses that sync-up electronically with the TV screen itself to give the appearance of 3D image on anything you play. I believe the TV comes with two pairs of glasses, and additional pairs can be purchased for substantial extra. It works with any movie or TV show, there is no requirement that it be filmed in 3D mode. The 3D-TV automatically analyzes that is moving on the screen, and then makes that item clearer and sharper, and things that are considered background are automatically made fuzzier, out of focus. The effect is really incredible.
One of the storage solutions on display was the entry-level IBM System Storage DS3524 disk system, which is a small 2U high cabinet that holds 24 drives. These are the small form factor 2.5 inch drives. It's amazing we can pack so many drives in such a compact rack-optimized enclosure!
Ingram Micro is one of IBM's technology distributors, and it was good to see it was a well-attended event.
With all of the distractions this week, from the Republican National Convention in Florida, to the Tropical Storm Isaac that hit New Orleans on the 7th anniversary of Hurricane Katrina, I thought I would continue this week's theme on the IBM zEnterprise EC12.
Processing an insurance claim: $56 U.S. dollars (USD) with mainframes, versus $92 USD with distributed servers.
Processing a mobile subscriber: $18.26 USD with mainframes, versus $26.12 USD with distributed servers.
IT cost for an ATM machine: $572 USD with mainframes, versus $1021 USD with distributed servers.
In the whitepaper [Total Economic Impact of IBM System z], Forrester Research interviews the executives of five existing mainframe clients, and through in-depth analysis of their deployments, is able to present a "composite" company with an IT-staff of 4,500 employees. The result is impressive: deploying an IBM System z had an ROI of 199 percent. That is a payback period of less than five months!
A finish this post with a quick [6-minute Youtube video], featuring my colleage, Nick Sardino. Nick and I have worked together in the past at various conferences and conventions.
I wasn't at the event, but thought it would be good to explain some basic concepts ofInformation Lifecycle Management (ILM),using the files on my iPod as an example. (Disclosure: IBM makes the technology inside many of Apple's computers, and so IBMers get to buy Appleproducts at employee prices. I own a Mac Mini based on IBM's POWER4 processor, and an iPod Photo 60GB model).
I have 20,000 MP3 music files, representing 106GB of data. This fits nicely on my 250GB external disk system attached to my Mac Mini, but won't all fit on my little 60GB iPod. I needed a way to decide what music I keep on bothmy iPod and Mac Mini, and which I keep only on my Mac Mini. When I am traveling, I am able to listen only to the musicin the first group, but when I am at home, I am able to listen to all my music in both groups.(Another disclosure: I use my Tivo connected to my LAN to play all my MP3 music through my home stereo system.I had my entire house wired with Cat5 to make this possible.)
Apple's iTunes software lets me decide which MP3 files are copied to my iPod using "playlists". A playlist is a list of songs. Fixed playlists are created manually, each song copied to its list in a specific order. Smart playlists are createdautomatically, via policy. I give it the criteria, and it finds the songs for me. If I import a new music CD,none of the songs will be added to any fixed playlists, but could be added to my smart playlists if I set the policiescorrectly. Apple iTunes supports both "include" and "exclude" methodologies.
I use primarily smart playlists, based on genre and rating. I have tried to keep the number of genre down to a small manageable list:
Rhythm & Blues
Of course, what I have for genre may not match what's in theGracenote database, so I sometimes have to makeupdates to match my convention. I've picked these based on my different "applications" for my music. For example, I listen to Ambient music to help me fall asleep on airplanes, but Rock when I exercise at the gym.
Next, I use the ratings from one to five stars. The advantage to the rating is that I can change them on-the-fly directly on my iPod. All other "metadata" has to be entered only from the keyboard of my Mac Mini.
Files for Mac Mini only, not copied to my iPod
Non-mix, copied to my iPod, but typically spoken words, such as language lessons
Mix, music to include in my music mixes
Keep on my iPod, but re-evaluate
So, I have five smart playlists, "One Star", "Two Stars", etc. for each rating, and have decidedto keep only the 2, 3, 4 and 5 star songs on my iPod, by simply putting check marks on those playlists to copythem over. I have about 50 songs with 5 stars, and 8000 with 3 stars, and the rest in the other categories,leaving me a few GB to spare.
I also have playlists for each genre, "Rock mix", "Pop Mix", "Ambient Mix", etc. where I have selected thosethat match the genre, AND have 3, 4 or 5 stars. In this manner, I can listen to a mix. If I find a song mis-classified for that genre, I change it to four stars, which serves as myreminder to re-evaluate when I am back at home on my Mac Mini. If I don't want a song in my mix, I just lowerit to 2 stars. I want it off my iPod altogether, I lower it to one star.
This method is simple enough, and allows me to enjoy my music right away, and more effectively, without having to wait for completely finishing my classification process.
Next week, I'm traveling to Africa (purely vacation, not related to my job, my senator, or myinvolvement in anycharitable organizations). My Canon camera has only a 1GB IBM Microdrive, but I am able to offloadmy pictures to my iPod, connected via USB cable, and review the pictures on the little 2-inch screen. By simply "unchecking" my 2-star and 3-starplaylists, and checking only those mixes I plan to take with me, I was able to clear 17GB of space, plenty ofroom for all my photos of elephants and giraffes, but still plenty of music to listen to. Thanks to my simple methodology, I was able to do this with minimal effort, and willhave no problem putting all my music back when I return.
When evaluating an ILM process, many people are overwhelmed by their fear of the classification process, when in reality it doesn't have to be so complicated.
Is there an "iTunes" for the storage in your datacenter? Yes! It's called IBM TotalStorage Productivity Center. It can help you list and classify all the files in your IT environment,including files in your internal disks inside the servers, your NAS and SAN external disk systems, across both IBM and non-IBM hardware.It's a good thing to consider as part of your overall ILM strategy.
