Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
5465-028 Standard SAN Volume Controller
5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!
Continuing my series of posts on the IBM Storage launch of February 9, I cover some new disk options.
IBM System Storage DCS9900
The DCS9900 uses a 4U enclosure to hold 60 (that's sixty, SIX-ZERO) drives! Normally, hot-swapable drives face the front or back surface of the rack, but these surfaces are valuable "real estate", so instead, the drives stick downward into a tray that rolls out, giving you full access to access any of the drives. The DCS9900 added support for 2TB (7200 RPM) SATA drives, and 600GB (15K RPM) SAS drives. The systems use ten-pack RAID-6 ranks, 8+2P.
(If this sounds a lot like the newly announced SONAS product, it should! The two products share "DNA", and so can be considered sister products, packing 60 drives into a 4U enclosure. By comparison, the SONAS initially only supports 1TB SATA in RAID-6 ten-packs 8+2P, and 450GB SAS in RAID-5 ten-packs 8+P+S, but now that 2TB SATA and 600GB SAS drives have been qualified for the DCS9900, we hope to qualify these for the SONAS soon as well.)
The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
Our newest offering is the IBM System Storage DS3000 series. Some analysts call this category "low end", but IBM prefers using "entry level". These have an attractivelow acquisition price, very easy to set up, and are intended for the Intel and AMD servers, such as IBMBladeCenter, System x, as well as servers from HP and Dell. Disk arrays in this category typically have listprices below $50,000 USD.
Our midrange offering is the IBM System Storage DS4000 series. These are designed for Linux, UNIX and Windows based workloads.Some call these server platforms "open systems", or sometimes "distributed systems". The DS4000 systems are rack-optimized modularunits, providing plenty of options and trade-offs between price and performance for price-sensitive customers.The "high end" model of the DS4000 series is the DS4800, and has very impressive performance characteristics.Disk arrays in this category typically have list prices in the $50,000 to $299,000 USD range.
IBM System Storage DS6000 seriesis one of our enterprise class offerings. DS6000 offers mainframe attachment comparable to what EMC DMX or HDS USP offer for their "enterprise class" or "high end" models, but uses substantially less power and in a much more compact modular rack-optimized packaging. Disk arrays in this category typically have list prices at $300,000 USD and above.
Super High End
Perhaps IBM and EMC can work together to petition IDC to adopt this as a new category, based on performance,rather than list price. Is the storage marketplace ready for a fourth category?As Chuck mentioned on his blog, IBM is #1 for mainframe disk storage, and perhaps it is because the IBM System Storage DS8000 Turbo series does so well on most mainframe workloads. No offering from EMC or HDS meet or beat the SPC benchmarks for the DS8000 Turbo. You can see the results in the Executive Summary or read the Full Report.
Thanks to IBM's innovative Adaptive ReplacementCache algorithm, IBM DS8000 performance shines best handling read-intensive random-access workloads that mainframes do most often. These types of workload are modeled by the SPC-1 benchmark. In cases of write-intensive, sequential processing, the differences are less substantial, as disk arrays from all manufacturers drop down to the native performance capabilities of the 10K and 15K RPM drives.
I'll give you a real example. Not long ago, I waspart of a team to help resolve a performance bottleneck on-site at the customer location. The customer had an interesting "composite application" where data was processed on AIX platform (IBM System p), which passed the data to a Linux partition running on the IBM System z mainframe,which in turn used Java SQL to post updates to a DB2 database on z/OS partition, which then wrote out through FICON adapters to an HDS USP device. IBM and HDS worked together to help the customer figure out why they weregetting disappointing throughput and response times. IBM brought in experts on AIX, TCP/IP, Java, Linux, z/OS and FICON. HDS had their experts too, and tried to improve performance by quadrupling the storage capacity, and spreading the data out across more spindles. That didn't work. As it turns out, HDS disk just couldn't deliver the performance required. The software and mainframe were all well tuned. They replaced the HDS withan IBM DS8000 array, and it met all the service level requirements. Problem solved.
The problem with having this new "super high end" category, of course, is that only IBM plays in it, so it wouldn'toffer the marketplace much of a comparison. For now, we'll just have to settle for being the fastest in the samecategory as EMC DMX and HDS USP.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers. Not all workloads are mission-critical or performance-sensitive. For less critical workloads, perhaps you may find EMC or HDS performance is "good enough".
But if performance is important to you, you should consider IBM on your list of vendors for your next purchase decision. Let IBM help you prove it to yourself, running your specific workloads side by side with your existing equipment.
Today, IBM announced its latest [BladeCenter S] with integratedredundant SAN fabric and disk storage inside the chassis. The tag line is "Data Center Capability, without the Data Center!"
I've gotten a few calls on this today, so I thought it would be good to blog about. To understand what is new,you need to understand what we had in other BladeCenter chassis. In those other chassis, there were up to 14 bladeservers on the front, and switch modules for FCP and Ethernet on the back. The entire chassis was rack-mountedto be connected to external devices.
The BladeCenter S was announced a year ago.With the new "BladeCenter S" chassis, the storage can be included inside the chassis, as well as connecting tothe outside world. It is designed to be stand-alone, rather than rack-mounted, plugs into a standard 100v-240v office power outlet,and includes a dust filter in caseyou keep it close to the floor, under your desk for example.
Click graphic at left for 4-minute video introduction.
(Here's also a more detailed[7-minute video] with fellow IBM colleague Alex Yost.)
Here's what you can get with the BladeCenter S:
Up to six(6) server blades that can do the work of 25-45 traditional servers.
Up to two(2) storage blades, each can have six(6) SAS or SATA disk drive modules (DDMs)
Up to four(4) switch modules, with a variety to choose from
Shared KVM, DVD/CD burner, and USB port. You can designate which blade has access to these, useful forinstalling software, attaching external devices, and so on.
The blades use either Intel, AMD or POWER processors, so you can run Windows, Linux, AIX, and [IBM i] (the newname for i5/OS V6R1).
Back 20 years ago, I worked with people with System/36 and System/38 systems. They loved it. Everything inone package. This grew into the AS/400 server. Having everything in one package was such an advantage thatIBM extended this to include a few "x86 blades" to run Windows applications but share the storage and networkresources.
Now IBM has taken this one step further. The older models assumed the majority of applications run underIBM's OS/400 or i5/OS operating system, but this new BladeCenter S does not make that assumption. You canmix and match different blade servers as needed, and run the operating systems you need.
This is an ideal packaging for Small and Medium sized Business (SMB), remote branch offices, and retail stores.In fact, more than 4,000 retail stores plan to run their operations using BladeCenter S this holiday season! For moreon this announcement, see the [IBM Press Release].
My XO laptop arrived Friday, December 21, this was from the [Give 1 Get 1 (G1G1)] program fromthe One Laptop Per Child (OLPC) foundation. The program continuesto the end of this month (December 31).
Here are my first impressions.
Setup was Easy
Open the box, put in battery, and plug in the adapter. Enter your name and choose your favorite color for your stick figurine. No passwords, no parameters. Software is pre-installed and ready to use.
The four pages of instructions included how to open the unit (not intuitive), where the various connection ports are located, what the home screen and neighborhood screen look like, safety warnings, and a nice letter from Nicholas Negroponte with an 800 phone number and website in case more help is needed.
Connecting to the internet was the first thing I did. The neighborhood screen shows all the Wi-Fi access points. It recognized mineand three others. I clicked on mine, entered my WEP key, and was connected.
This is a Linux operating system running the Sugar user interface.There are four screens:
Neighborhood - shows all Wi-Fi access points
Friends - shows all other XO laptops nearby, in my case I am all alone
Home - your stick figurine with all the applications you can choose from are represented as icons at the bottom, just like OS X on my Mac Mini, or the launchpad on my Windows XP. Left panel for clipboard items.
Application - Applications run in full-screen mode
Four buttons across the top allow you to jump to any screen instantly.Everything else is single left-click. No double-clicks or right-clicks.
A circle on the home screen designates which applications are running, and how much of the available 256MB RAM they are consuming. This makes it easy to seeif you can run more applications or need to shut something down. Youcan jump to any application, or shut it down, from this view.
Shutting down the XO is done by clicking your stick figurine,and choosing shutdown.
I fired up the browser. The default 'home page' offers some help offline, as well as links to online resources and a google search bar. The full-color 1200x900 is very easy to read. You can hit ctrl+plus to make the fonts bigger. In bright sunlight, the screen turns automatically to greyscale.The built-in browser is easy enough to use, with standard back, forward, re-load, and bookmark buttons. The URL entry field also shows the pages title. It doesn't have tabs to see multiple pages at the same time, but I was able to fire up a second instance of the browser, so thatI could alt-tab back and forth between the two web sites.
There are so many applications that they don't all fit on the bottom of the screen.Left and right tab buttons will display the next set. I don't know if it is possible to re-order the icons, but I can certainly see some applications appealing to different ages, and perhaps re-ordering them into age-specific groups might be helpful.
Basic applications include the Abiword word processor, a PDF viewer, a simple paint program, calculator, chat, and news RSS feed reader; TamTam music to play and edit compositions; and some learn-to-program-a-computer software including Pippy, Etoys, and TurtleArt.
The 'record' program lets you take 640x480 pictures with the built-in camera, up to 45 seconds of video and audio recording. The picture abovewas taken with my XO, and edited online using [snipshot.com]. Another program can be usedto make video calls to another computer, similar to Skype or IBM Lotus Sametime.
The XO has built-in microphone and speakers, but also microphone and speaker ports, as well as three USB ports, and a slot for an SD memory card.
The QWERTY keyboard is designed for small children hands, I found myself using my two index fingers in a hunt-and-peck style. People who use Blackberry's or other hand-held devices might be able to use their two thumbs instead. Also, I am not used to a touchpad as the pointing device. My other laptops have a red knob between the G/H/B keys that acts like a joystick. So, I decided to attach my Apple keyboard/mouse to one USB port, which allows me faster typing and better resolution with my mouse.
I also inserted a 1GB SD card into the slot. Getting to the SD slot was challenging--you have to rotate the screen 90 degrees so that the lower right corner is over the laptop handle. It appears I need to purchase some tweasers to get my SD card back out, so until then, it will remain there as permanent addition to my XO.
A terminal application provides a command line interface into Linux.
The 'vi' editor is installed, in case I need to make changes to fstab or anythingelse in my /etc directory.
There is no S-video or VGA port. However, a teacher could probably fold thislaptop up in e-book mode and lay it flat on an [overhead projector] since the screen can handle bright sunlight in black-and-white mode.
The Journal and the Clipboard
There are no folders or subdirectories here. The journal acts as your desktop, holding all the files you have referenced, sorted in chronological order with the most recent on top. The journal application is started automatically when you boot up.My SD card is shown as a separate entry at the bottom right corner, but I have access only to files on my top-level directory on the card. The journal allows you to drag and drop between the system and the SD flash card.The list can be filtered by file type and application, so finding things is easy.You can also copy anything in the journal to the clipboard, appearing on the leftpanel of the home screen. You can then launch or paste this into other applications.
Pressing Alt-1 takes a 1200x900 snapshot of the current screen, and puts it into the journal.On websites that allow you to upload a file, including GMAIL, snipshot.com, etc. the browse button brings up the journal. So, for example, you could take a snapshot of the current webpage or paint creation, and send it as an attachment to someone via GMAIL. Google has an XO-enabled version of GMAIL that you can download from the OLPC activities page.
This entire post, including the picture above, was done with the XO laptop itself. I am impressed with the thought that went into this design, and I see great potential here. The interface adequately hides the Linux operating system for those who just want to use the computer, but makes it readily accessible for those who want to learn more about the Linux operating system and computer programming.
On Wednesday, I walked through the gardens of [The Grotto] on Sandy Blvd, ate a German lunch at [The Rheinelander], then visited the [Crown Point Vista House] along the [Columbia River Gorge]. There were several fabulous waterfalls that could be seen from the parking area without hiking into the wilderness. We wouldn't want to encounter a bear in the woods, or a cow in the field!
Afterwards, I drove to the [Timberline lodge] at the peak of Mt. Hood to watch the snow fall and have dinner and drinks. This is the lodge featured in the movie ["The Shining"].
Thursday was a Spa day, which I spent relaxing at the pool and sauna. In the evening, I had dinner at [Henry's Tavern], and then shopped at [Powell's Books].
In the afternoon, Rafael, Mo and I explored Portland's waterfront and various bridges via [Segway tour]. The cherry blossoms along our path were in full bloom. If you have not ridden on one of these Segway scooters, they are a lot of fun!
On Saturday, Portland held their [Saturday Market] with arts and crafts for sale. This is similar to Tucson's 4th Avenue Street fair. The difference is that the "Saturday Market" occurs every Saturday of the year and Tucson's 4th Avenue Street Fair occurs only twice per year. The weather was very nice, so, many of the locals were in t-shirts and shorts. A live concert by [Grupo Condor] were playing on the main stage.
I walked past the [Voodoo Donuts store]. There was a long line to get in. A woman leaving the store carrying a pink donut box complained she waited 2 hours just to spend $28 for a dozen donuts. The magic is in the hole!
Getting out of the hustle and bustle of the Saturday Market, I had some green tea at the [Lan Su Chinese Garden]. A sister city to Portland is Suzhou, China, and this garden was very peaceful to walk through.
I went back to Powell's Books, did some shopping for shoes at [Dr. Martens], and had some pizza and salad at [Sizzle Pie] next door.
Nearly everything was closed on Easter Sunday, so I went down to the [TulipFest at the Wooden Shoe Tulip Farm] in Woodburn, OR. This was the opening weekend, with over 40 acres of flowers to walk through, various food carts, wine tasting, and rides for the kids.
Getting back to Tucson proved to be a bit challenging. The flight from Portland to San Francisco was delayed due to fog, so we got re-routed to Seattle, then back to Los Angeles, and finally to Tucson.
With over 2,000 technical sessions and 500 client testimonials, the event can be intimidating. For those of you attending this conference for the first time, I have some advice:
Review all the sessions you want to attend.
Don't limit yourself to just sessions in your area of job responsibility. Venture out. Look for adjacent spaces. Attend a session of two that you might learn something completely new and different.
Build your schedule in advance. The mobile app [IBM Events] can help you plan out your week.
Select one to five sessions per time slot, this gives you the choice to make a final selection, if there are last minute cancellations, or you discover a room is completely full.
Be mindful that some sessions are at the MGM Grand hotel, and others at the Mandalay Bay Resort, so you may need to account for travel time. This [Week-at-a-Glance] can help. I will be focusing my efforts at the Mandalay Bay.
Here's my first cut at my schedule. Maybe this will help you organize your own.

I will be there all week! Contact me if you want to get together.
Continuing my coverage of the IT Security and Storage Expo in Brussels, Belgium, here is my post on the presentations I gave during the week.
There were four presentations each day. Of the five rooms, I was assigned one room in which to give all of my presentations, room 3. My room was quite large, with sixty seats.
It is a good idea for public speakers to understand Dutch, French, German and English in Belgium. In recognition of the fact that Belgians are multi-lingual, I started each session with "Goede Middag, Bon Jour and Good Afternoon!" and ended each with "Dank U, Merci and Thank you for attending!"
12:00 to 12:30pm

Storage, Server and Network in one Flexible and Integrated solution! The PureSystems family
The sessions were all half-hour slots. The only presentation that I had a challenge getting down to 30 minutes was my session on "New Generation of Storage Tiering" in which I was asked to cover Easy Tier sub-LUN automated tiering, Server-to-Storage cooperative caching, Texas Memory Systems, hierarchical storage Management (HSM), Active Cloud Engine, and SmartCloud Storage!
Helping me out were three local IBM interns. From left to right: Joelle, Clara and Bryan. I hadn't noticed that there were only short breaks between sessions, all of this time consumed with one-on-one discussions with clients, so the interns were kind enough to fetch me snacks and drinks.
Joelle and Bryan speak Dutch, which is similar to the local Flemish language. Clara speaks French, which came in handy for translations.
I would like to thank my room monitors: Jolijn, Ella and Chloe. All three are local college students hired by the conference for the two days to scan name badges and count bodies in seats.
(I had to ask Jolijn to write her name on a piece of paper because it is Dutch and I had no clue how to spell it for this blog post.)
While it might appear that room 3 was "The Tony Pearson Show -- all Tony, all the time!" there were actually worthwhile sessions in the other rooms. Fellow blogger Jon Toigo [known for his DrunkenData blog] presented "Storage Infrastruggle 2013 -- Containing Storage Costs without Sacrificing Access, Protection or Management". My IBM colleague Ron Riffe presented a vendor-neutral look at Storage Hypervisors.
If the attendees wanted copies of my presentations, they were directed to get their name badge scanned at the IBM and I.R.I.S-ICT booth, all the way at the other end of the hall, and my presentations would be emailed to them.
(For those who have missed it, you can find all five of my presentations uploaded to the [IBM Expert Network] on Slideshare.)
Finally, I would like to thank my IBM colleagues who helped me develop and review my presentations: Brigitte Van Den Eynde, Joe Hayward, Jeff Jonas, Tom Deutsch, Chris Saul, Marisol Diaz, Iliana Garcia, Harley Puckett, Jack Arnold, and Steve McKinney.
I got some exciting news today that i would like to share with my readers!
Several years ago, I mentored a young 19-year Tarun Pondicherry from India to work on one of Google's Summer-of-Code project. We worked on a simple blogging system to help teach grade school children in Uruguay how to write their own blogs.
Well, that was six years ago, but I have kept in touch, and today learned that Tarun has been working on an exciting project to teach young kids to write computer programming code.
It's called "LightUp" and the idea is quite simple. Using a simple programming interface, you can program the machine to light up based on what the programming code specifies. It is immediate feedback for the child to explore the world or software logic. Already they have helped kids around the world build over 100,000 circuits!
And speaking of learning new innovations, I will be at the [IBM Edge 2015 conference] next week in Las Vegas. There will be traditional lectures about IBM's latest innovations, mixed with hands-on labs and plenty of exciting demos, because Adults need to learn too!
Wrapping up my week teaching Top Gun class in Sydney, Australia, I could not resist taking a photo of the cityscape.
Sydney is a beautiful city, and the view from the 13th floor of the IBM Centre at St. Leonards in North Sydney is always worth a picture!
Vic, Scott and I all have engineering backgrounds, so it is easy for us to drop down into the technical weeds in discussing each product and solution. However, the student feedback from both Auckland and Sydney was that some of our material was just too technical.
Do they plan to store and process their data in house? IBM's [focus on Cloud is paying off], and IBM SmartCloud offerings might make a lot of sense for many clients.
Do they plan to centralize their IT? Some companies centralize all of their IT, and others distribute the decision-making to departments, remote office and branch office locations. For the latter, use the ROBO approach to selling.
Do they prefer one-stop shopping? In my now infamous post [Supermarkets and Specialty Shops], I mentioned research that found our clients fall into two camps. Those that favor one-stop shopping from IBM, HP, Cisco, Dell or Oracle, versus those that prefer to buy from the many IT equivalent of butchers, bakers and candlestick makers like EMC, HDS, or NetApp. For those clients that fall in the latter camp, focus on IBM's best-of-breed products.
IT Supermarket competition? The final group are clients that prefer one-stop shopping, but have not yet made up their mind between IBM versus the [IBM wannabees]. Focus on IBM's synergy between storage, servers, software, switches and services.
Last week, we celebrated Joe's birthday in Auckland. This week, it was Vic's turn, so we went to the Garfish restaurant at Manly beach. Here we are with bacon-enhanced oysters.
The four-day class finished Thursday afternoon, and I went out with some of the students to celebrate their graduation. I started with beers at the Cabana, then wine at [the Ivy Room], and finally dinner at Uccello on the rooftop [Pool Club]. Dinner was awesome: pork sausage-stuffed olives to start, roasted chicken with polenta, and finally a capuccino to finish the meal.
I would have never found these places on my own, and the students provided me some interesting feedback about the class and how to improve it.
I travel a lot. In the first six months of this year, I was on the road 17 of the 26 weeks. This week, I am visiting clients in beautiful Minneapolis, MN.
Several readers have asked me what mobile phone or web apps I find the most useful, and here are my top three. For each, I will explain how I use them, and why they are useful.
(FTC Disclosure: I work for IBM, and have no financial connections to any of the companies mentioned below, and have not been compensated in any way to mention them on this post. IBM has selected Concur as its travel platform, which runs TripIt mentioned below. This blog post can be considered a "paid celebrity endorsement" for each of the three sites below.)
[Rome2Rio] is one I use long before I plan my trip, and works both on my mobile phone as well as web application. Many people use apps like "Google Maps" for driving directions from point A to point B. But Rome2Rio handles airlines, trains and other alternative modes of transportation. It also provides estimated prices for each mode of transportation.
Landing in Gatwick Airport, I used Rome2Rio to figure out the most cost-effective way to get to my hotel on Southampton Row. A taxi would have been $160-200, Ride-share like Uber or Lyft $75-95, and train $17-28. I chose the train and saved a lot of money!
Rome2Rio is a great app, both for advanced planning, as well as dealing with situations in the moment. I have it bookmarked on my browser, and the app installed on my phone.
Long before IBM signed on Concur as its travel expense and trip planning tool, I was using [TripIt]. It automatically enters all of my airfare, hotel and car rental reservations into a single chronological itinerary, but then lets me add everything in between, such as meetings, dinner restaurant plans, and other activities.
While I am planning my travels, TripIt ensures I have all the connections I need. If I land at this airport, do I have a rental car or other transportation to the hotel? This forces me to get in advance all of the times and locations of every client dinner, briefing, or other meeting, so that I can plan how to get from point A, to B, to C, accordingly.
A few days before my trip, I can print out my TripIt itinerary, to PDF format file to send to my family and co-workers.
While traveling, I have the TripIt app to have all the information I need close at hand, including hotel address locations, or confirmation numbers once I arrive to the hotel.
[FlightStats] will show you the status of all flights, on any airline. Just enter the 2-character airline code, like AA for American Airlines, or DL for Delta Airlines, then the flight number. Here are the different ways I find this useful:
When I land at an airport connection, but have not yet left the plane, I can use FlightStats to determine which gate I have arrived at, and which gate I need for my next flight. This will give me a good sense of how much time I have, do I need to hurry, can I stop for a snack, and so on.
FlightStats seems to be more up-to-date than computer screens at the airport. I have learned of flight delays from FlightStats sooner than I have from the computer screens or gate agents.
If my flight is canceled or delayed, FlightStats also can find flights from point A to B using real-time information.
Are there any apps or web sites you recommend? Please comment below!
Continuing this week's theme about the future, fellow blogger, published author, and futurist David Houle is coming out with a new book this month titled [Entering the Shift Age]. This is a follow-on to his book, [The Shift Age].
Since this book cites IBM studies explicitly, his PR department asked me to review it. If you are an aspiring author that has a book you want me review, and it relates to the topics my blog covers like Cloud, Big Data, storage, and the explosion of information, feel free to send me a copy!
(FTC Disclosure: I work for IBM. I was not paid by anyone to mention this book on my blog. I was provided an "Uncorrected Advanced Copy" of this book at no cost to me for this review. I do not know David Houle personally, have not read any of his prior works, nor have I ever seen him speak at public events. This post is neither a paid nor celebrity endorsement of this author, his book, nor any other books by this author.)
First, let's get a few details out of the way:
Title:Entering the Shift Age, 284 pages Author: David Houle, futurist Genre: Non-fiction, trends and predictions
Publisher: Sourcebooks, Inc. Publish date: January 2013
As I mentioned in my post [Historians vs. Futurists], there is only one past, but there are many potential futures. There seems to be as many futurists out there as there are potential futures. I suspect not everyone will agree with all that David has written. However, this reminds me of one of my favorite quotes:
"When two futurists always agree, one is no longer necessary." -- old Italian adage
In his book, David asks a series of thought-provoking questions, then answers them with his views and opinions on how the future will roll out:
Is humanity now entering a new age that is different than the Information age?
If so, what should we call it?
Which forces are driving this new age?
How will this impact various aspects and institutions of society?
David feels humanity is indeed entering a new age, which he calls the Shift Age. This is driven by three forces: the shift to globalization of culture and politics, the flow of power and influence to individuals, and the acceleration of electronic connectedness.
In a sense, David is like a hunter-gatherer from the Stone age, hunting down trends and gathering ideas from others. In much the same way my compost brings renewed purpose to the rinds and pits of my fruits and vegetables, David's book does a good job paraphrasing the works of many of today's leading futurists.
David predicts the decade we are now in, the 2010's, will mark the end of the Information age, a transition period to this new era, that will lead to transformations in government, education, health, technology, and energy.
Over the past two weeks, I had time to enjoy a variety of movies. I had seen several whose stories wrapped around key moments of transition.
"Gone with the Wind", as well as the new offering "Lincoln" from Steven Spielberg. Both are set in the 1860's, the time of the [American Civil War], pitting the Industrial-age forces of the North, against the Agricultural-age economy of the South. This time saw the transition from slavery to freedom.
"Doctor Zhivago", set in the time of World War I, on the German-Russian front, as well as the Russian Revolution of 1917, and the resulting Civil War between the Red Guard and the White Army. This saw the transition from a Russian government ruled by Czars, to one ruled by the people through Communism.
"Lawrence of Arabia", also set in the time of World War I, but south in Arabia. T. E. Lawrence was able to bring several warring Arab tribes together to defeat the Turks, and was a key figure in the transition to an Arab National Council.
Some might call these completely unexpected [Black Swan] events, while others might feel they are merely fortunate (or misfortunate) sequences of events that led to inevitable social change. Has something happened, or will something happen later this decade, that will drive us to leave the Information Age?
David's previous book, The Shift Age, was published back in 2007, and a lot has happened in the past six years: a global financial melt-down recession; the Arab Spring uprisings in the Middle East; Barack Obama was elected and re-elected; man-made climate change in the form of hurricanes, tsunamis and superstorms hit various parts of the world; brush fires lit up Australia, and BP's Deepwater Horizon oil rig exploded off the Gulf coast, just to name a few.
David's new book reflects the impact of these recent events, from discussions on his [Evolutionshift] blog, to Q&A sessions he has after his public speaking presentations. For those who are not interested in the wide array of topics he covers in this one book, David also offers [a dozen different mini-eBooks] that cover specific topics like [Technology, Energy and Health].
My Rating: Moist and Flaky
Who should read this book: If you are a time-traveler from 1975 that came to this decade to learn all about what your future has in store, but can only select one book to read before you zoom back to your own time period, this would be the book I recommend.
I do not want to imply this is a quick read, or one that you can't put down once you start reading it. Just like you should not gulp down a full bottle of cheap Vodka in one sitting, this book should be read over a series of days, as I did, so that you can mull over in your mind the different points and thoughts he is trying to convey.
It's official! My "blook" Inside System Storage - Volume I is now available.
This blog-based book, or “blook”, comprises the first twelve months of posts from this Inside System Storage blog,165 posts in all, from September 1, 2006 to August 31, 2007. Foreword by Jennifer Jones. 404 pages.

How IT storage impacts society and industry
You can choose between hardcover (with dust jacket) or paperback versions:
This is not the first time I've been published. I have authored articles for storage industry magazines, written large sections of IBM publications and manuals, submitted presentations and whitepapers to conference proceedings, and even had a short story published with illustrations by the famous cartoon writer[Ted Rall].
But I can say this is my first blook, and as far as I can tell, the first blook from IBM's many bloggers on DeveloperWorks, and the first blook about the IT storage industry.I got the idea when I saw [Lulu Publishing] run a "blook" contest. The Lulu Blooker Prize is the world's first literary prize devoted to "blooks"--books based on blogs or other websites, including webcomics. The [Lulu Blooker Blog] lists past year winners. Lulu is one of the new innovative "print-on-demand" publishers. Rather than printing hundredsor thousands of books in advance, as other publishers require, Lulu doesn't print them until you order them.
I considered cute titles like A Year of Living Dangerously, orAn Engineer in Marketing La-La land, or Around the World in 165 Posts, but settled on a title that matched closely the name of the blog.
In addition to my blog posts, I provide additional insights and behind-the-scenes commentary. If you go to the Luluwebsite above, you can preview an entire chapter in its entirety before purchase. I have added a hefty 56-page Glossary of Acronyms and Terms (GOAT) with over 900 storage-related terms defined, which also doubles as an index back to the post (or posts) that use or further explain each term.
So who might be interested in this blook?
Business Partners and Sales Reps looking to give a nice gift to their best clients and colleagues
Managers looking to reward early-tenure employees and retain the best talent
IT specialists and technicians wanting a marketing perspective of the storage industry
Mentors interested in providing motivation and encouragement to their proteges
Educators looking to provide books for their classroom or library collection
Authors looking to write a blook themselves, to see how to format and structure a finished product
Marketing personnel that want to better understand Web 2.0, Second Life and social networking
Analysts and journalists looking to understand how storage impacts the IT industry, and society overall
College graduates and others interested in a career as a storage administrator
And yes, according to Lulu, if you order soon, you can have it by December 25.
The blog team is working on re-directs for those who don't see this in time. Depending on which RSS feed reader you use, you may need to unsubscribe/re-subscribe to re-activate. You can updatethe URL for the feed to one of these:
IPv4, IPv6, Wireless Mesh networking? No problem! You know linux networking inside and out
Extensive knowledge of BIND, DHCPD, Squid, Apache, security, etc.
Experience working with [Moodle] would be most excellent (it is basically a PHP web application that maintains MySQL databases for lesson plans, homework assignments and other school related information)
Adept with Python scripting or could learn it quickly. OLPC has standardized on Python for scripting (although knowledge in Perl and PHP won't hurt either)
You look to implement a practical solution that less skilled sysadmins can easily maintain over a cooler but more complicated solution.
You play well with others. You don’t alienate collaborators with rude e-mails that assert your technical superiority (even though you are)
Your primary concern is meeting the educational needs of kids and teachers. Your rate technical awesomeness a distant second to meeting those critical needs.
I've been working with Dev, Bryan and Sulochan for the past three months (remotely here from Tucson, AZ)but we've come to a point where we need on-site expertise. I will continue to provide remote support.
Given the number of readers who have contacted me over the past year looking for an IT job (or a different job because they are not happy where they are), this could be an amazing experience.
This week I am in Minneapolis, MN, so was hoping that the complicated process of moving this blog over to "MyDeveloperWorks" would happen while I was gone, but alas, that does not appear to be the case.
Meanwhile, my partner in crime, Barry Whyte, has moved his blog [Storage Virtualization]successfully over to the new server.
Perhaps next week. If all goes well, the URL links should redirect correctly, but those of you out there using feed readers might require you to re-subscribe to get the right RSS feeds.
Tuesday is always good for announcements. Today, Gartner, Inc. announced that IBM has taken over HP in its climb to the top. I'll quote directly from today's press release:
STAMFORD, Conn., March 6, 2007 — Worldwide external controller-based (ECB) disk storage revenue totaled $15.2 billion in 2006, a 4.1 percent increase over 2005 revenue of $14.6 billion, according to Gartner, Inc.IBM overtook Hewlett-Packard for the No. 2 position in 2006 (see Table 1). IBM’s worldwide ECB market share increased to 15.8 percent, while HP’s market share dropped to 13.1 percent.
IBM beat HP both in 4Q06, as well as 2006 full year.You can read more about it from Gartner Dataquest report “Market Share: Disk Array Storage, All Regions, All Countries, 1Q05-4Q06" on their website. (Note: non-IBMers might need an account with Gartner to access this, not sure)
The focus was on external controller-based disk, not external controller-less SCSI/SAS disk, not disk arrays posing as virtual tape libraries, nor any disk sold inside HP, Sun, IBM or Dell servers. This is to compare with disk-only vendors such as EMC and HDS. The revenues reflect hardware only, including hardware-related parts of financial leases and managed services. Revenues from optional priced software features such as multi-pathing drivers, management software, or advanced copy services were excluded.I discussed these types of analyst reports back in blog post last September: Space Race Heats Up.
These marketshare numbers are based on revenues, not units or terabytes. When a box gets sold, the revenue was counted toward the vendor that sold it, not the manufacturer that built it. In this last report:
When Dell sells an EMC box, it gets counted as Dell. When Fujitsu Siemens sells an EMC box, it gets counted as "Other".
When HP sells an HDS box, it gets counted as HP. When Sun sells the HDS box, it gets counted as Sun.
When IBM sells its System Storage N series (from the OEM agreement with NetApp), it gets counted as IBM. Both IBM and NetApp experienced growth in the NAS/unified storage arena.
It's still cold here in the Washington DC area, but at least good news like this helps warm me up!
Back in June, I mentioned this blog was [Moving to MyDeveloperWorks] which is based on IBM Lotus Connections.
Finally, the move is complete for all bloggers. If you are having problems with the redirects, you might need to unsubscribe and re-subscribe in your RSS feed reader. Here are the new links for several IBM bloggers that have moved over:
My colleague, Marissa Benekos, is on location with her video camera in Orlando, Florida for theComputerWorld [Storage Networking World] conference.
The IT specialists from the IBM booth were excited at David Bricker's debut on YouTube.Here's the rest of the gang in this [video].
Here's Andy Monshaw, General Manager of IBM System Storage and keynote speaker at this SNW event, summarizingIBM's "Information Infrastructure" strategy in 60 seconds in this [Youtube video].
This last video is Clod Barrera talking about the importance of security. Clod is an IBM Distinguished Engineerand Chief Technical Strategist for IBM System Storage product line. Here is his[Youtube video]
It looks like Marissa is having a lot of fun taking these videos at the event.More videos, as we get them, will be posted to the [IBM videos channel].
In my post yesterday [Spreading out the Re-Replication process], fellow blogger BarryB [aka The Storage Anarchist]raises some interesting points and questions in the comments section about the new IBM XIV Nextra architecture.I answer these below not just for the benefit of my friends at EMC, but also for my own colleagues within IBM,IBM Business Partners, Analysts and clients that might have similar questions.
If RAID 5/6 makes sense on every other platform, why not so on the Web 2.0 platform?
Your attempt to justify the expense of Mirrored vs. RAID 5 makes no sense to me. Buying two drives for every one drive's worth of usable capacity is expensive, even with SATA drives. Isn't that why you offer RAID 5 and RAID 6 on the storage arrays that you sell with SATA drives?
And if RAID 5/6 makes sense on every other platform, why not so on the (extremely cost-sensitive) Web 2.0 platform? Is faster rebuild really worth the cost of 40+% more spindles? Or is the overhead of RAID 6 really too much for those low-cost commodity servers to handle.
Let's take a look at various disk configurations, for example 3TB on 750GB SATA drives:
JBOD: 4 drives
JBOD here is industry slang for "Just a Bunch of Disks" and was invented as the term for "non-RAID".Each drive would be accessible independently, at native single-drive speed, with no data protection. Puttingfour drives in a single cabinet like this provides simplicity and convenience only over four separate drivesin their own enclosures.
RAID-10: 8 drives
RAID-10 is a combination of RAID-1 (mirroring) and RAID-0 (striping). In a 4x2 configuration, data is striped across disks 1-4,then these are mirrored across to disks 5-8. You get performance improvement and protection against a singledrive failure.
RAID-5: 5 drives
This would be a 4+P configuration, where there would be four drives' worth of data scattered across fivedrives. This gives you almost the same performance improvement as RAID-10, similar protection againstsingle drive failure, but with fewer drives per usable TB capacity.
RAID-6: 6 drives
This would be a 4+2P configuration, where the first P represents linear parity, and the second represents a diagonal parity. Similar in performance improvement as RAID-5, but protects against single and double drive failures, and still better than RAID-10 in terms of drives per TB usable capacity.
For all the RAID configurations, rebuild would require a spare drive, but often spares are shared among multiple RAID ranks, not dedicated to a single rank. To this end, you often have to have several spares per I/O loop, and a different set of spares for each kind of speed and capacity. If you had a mix of 15K/73GB, 10K/146GB, and 7200/500GB drives, then you would have three sets of spares to match.
In contrast, IBM XIV's innovative RAID-X approach doesn't requireany spare drives, just spare capacity on existing drives being used to hold data. The objects can be mirroredbetween any two types of drives, so no need to match one with another.
All of these RAID levels represent some trade-off between cost, protection and performance, and IBM offers each of theseon various disk systems platforms. Calculating parity is more complicated than just mirrored copies, but this can be done with specialized chips in cache memory to minimize performance impact.IBM generally recommends RAID-5 for high-performance FC disk, and RAID-6 for slower, large capacity SATA disk.
However, the questionassumes that the drive cost is a large portion of the overall "disk system" cost. It isn't. For example,Jon Toigo discusses the cost of EMC's new AX4 disk system in his post [National Storage Rip-Off Day]:
EMC is releasing its low end Clariion AX4 SAS/SATA array with 3TB capacity for $8600. It ships with four 750GB SATA drives (which you and I could buy at list for $239 per unit). So, if the disk drives cost $956 (presumably far less for EMC), that means buyers of the EMC wares are paying about $7700 for a tin case, a controller/backplane, and a 4Gbps iSCSI or FC connector. Hmm.
Dell is offering EMC’s AX4-5 with same configuration for $13,000 adding a 24/7 warranty.
(Note: I checked these numbers. $8599 is the list price that EMC has on its own website. External 750GB drivesavailable at my local Circuit City ranged from $189 to $329 list price. I could not find anything on Dell'sown website, but found [The Register] to confirm the $13,000 with 24x7 warranty figure.)
Disk capacity is a shrinking portion of the total cost of ownership (TCO). In addition to capacity, you are paying forcache, microcode and electronics of the system itself, along with software and services that are included in the mix,and your own storage administrators to deal with configuration and management. For more on this, see [XIV storage - Low Total Cost of Ownership].
EMC Centera has been doing this exact type of blob striping and protection since 2002
As I've noted before, there's nothing "magic" about it - Centera has been employing the same type of object-level replication for years. Only EMC's engineers have figured out how to do RAID protection instead of mirroring to keep the hardware costs low while not sacrificing availability.
I agree that IBM XIV was not the first to do an object-level architecture, but it was one of the first to apply object-level technologies to the particular "use case" and "intended workload" of Web 2.0 applications.
RAID-5 based EMC Centera was designed insteadto hold fixed-content data that needed to be protected for a specific period of time, such as to meet government regulatory compliance requirements. This is data that you most likelywill never look at again unless you are hit with a lawsuit or investigation. For this reason, it is important to get it on the cheapest storage configuration as possible. Before EMC Centera, customers stored this data on WORM tape and optical media, so EMC came up with a disk-only alternative offering.IBM System Storage DR550 offers disk-level access for themost recent archives, with the ability to migrate to much less expensive tape for the long term retention. The end result is that storing on a blended disk-plus-tape solution can help reduce the cost by a factor of 5x to 7x, making RAID level discussion meaningless in this environment. For moreon this, see my post [OptimizingData Retention and Archiving].
While both the Centera and DR550 are based on SATA, neither are designed for Web 2.0 platforms.When EMC comes out with their own "me, too" version, they will probably make a similar argument.
IBM XIV Nextra is not a DS8000 replacement
Nextra is anything but Enterprise-class storage, much less a DS8000 replacement. How silly of all those folks to suggest such a thing.
I did searches on the Web and could not find anybody, other than EMC employees, who suggested that IBM XIV Nextra architecture represented a replacement for IBM System Storage DS8000. The IBM XIV press release does not mentionor imply this, and certainly nobody I know at IBM has suggested this.
The DS8000 is designed for a different "use case" andset of "intended workloads" than what the IBM XIV was designed for. The DS8000 is the most popular disk systemfor our IBM System z mainframe platform, for activities like Online Transaction Processing (OLTP) and large databases, supporting ESCON and FICON attachment to high-speed 15K RPM FC drives. Web 2.0 customers that might chooseIBM XIV Nextra for their digital content might run their financial operations or metadata search indexes on DS8000.Different storage for different purposes.
As for the opinion that this is not "enterprise class", there are a variety of definitions that refer to this phrase.Some analysts look at "price band" of units that cost over $300,000 US dollars. Other analysts define this as beingattachable to mainframe servers via ESCON or FICON. Others use the term to refer to five-nines reliability, havingless than 5 minutes downtime per year. In this regard, based on the past two years experience at 40 customer locations,I would argue that it meets this last definition, with non-disruptive upgrades, microcode updates and hot-swappable components.
By comparison, when EMC introduced its object-level Centera architecture, nobody suggested it was the replacement for their Symmetrix or CLARiiON devices. Was it supposed to be?
Given drive growth rates have slowed, improving utilization is mandatory to keep up with 60-70 percent CAGR
Look around you, Tony- all of your competitors are implementing thin provisioning specifically to drive physical utilization upwards towards 60-80%, and that's on top of RAID 5/RAID 6 storage and not RAID 1. Given that disk drive growth rates and $/GB cost savings have slowed significantly, improving utilization is mandatory just to keep up with the 60-70% CAGR of information growth.
Disk drive capacities have slowed for FC disk because much of the attention and investment has been re-directed to ATA technology. Dollar-per-GB price reduction is slowing for disks in general, as researchers are hitting physicallimitations to the amount of bits they can pack per square inch of disk media, and is now around 25 percent per year.The 60-70 percent Compound Annual Growth Rate (CAGR) is real, and can be even growing faster for Web 2.0providers. While hardware costs drop, the big ticket items to watch will be software, services and storage administrator labor costs.
To this end, IBM XIV Nextra offers thin provisioning and differential space-efficient snapshots. It is designed for 60-90 percent utilization, and can be expanded to larger capacities non-disruptively in a very scalable manner.
