Did you miss your chance to attend Storage Networking World last week? IBM has some upcoming conferences that might be of interest to you.
IBM Systems Conference 2009
In this inaugural event, IBM executives, developers and industry experts reveal the latest innovations, trends and directions. In the span of three full days, you will hear and see technologies demonstrated that are needed to transform and respond effectively in these economic times.
There will be three tracks:
IBM Systems -- Including storage, mainframe, POWER and x86 systems
Solutions for a Dynamic Infrastructure
Professional Development -- including negotiation skills, project management and TCO analysis
IBM System Storage and Storage Networking Symposium
If the above conference is too broad, we have a more storage-specificconference. The [IBM System Storage and Storage Networking Symposium] brings IBM storage developers, architects, technical experts, solution providers and customer speakers together in one place to show you how to address the growing challenge of managing and securing retention managed data. You'll also learn about the latest IBM System Storage™ portfolio product announcements.
I have spoken at these perhaps 12 of the last 14 years. The list of presenters has not yet finalized, so I do not yet know if I will actually be there this year.
Two exciting things are new this year. First, instead of being in San Diego or Las Vegas, it will be held in Chicago, Illinois instead!Secondly, you get a two-for-one with the [IBM System x and BladeCenter Technical Conference]. That's right, they are co-located there in Chicago so that you can attend sessions from both! Perhaps you spend 80 percent of your time on storage, and 20 percent on x86 servers, or 80 percent servers and 20 percent storage, now you can register for one price, and decide when you get there.
If you act soon, you can save money with the early-registration discount by May 31.
Hopefully, this will give you enough time to plan and make travel arrangements!
In addition to keynote speakers Curtis Tearte, General Manager for IBM System Storage, and Clod Barrera, Chief Technical Strategist, my colleague Jack Arnold and I from the [IBM Tucson Executive Briefing Center] will present four topics each.
We have a lot to cover, so I will do the quick recap today, and then go in-depth on subsequent posts.
IBM FlashSystem 840 and V840
The FlashSystem now offers a high-voltage 1300W power supply. There are two supplies providing redundancy. In the unlikely event that you are doing maintenance on one of them, the other supply handles all the workload. With the original power supply, the system slowed down the clock speeds to reduce electrical demand. The new power supplies can handle full performance.
Also, the Graphical User Interface (GUI) now holds 300 days of performance data with pan-and-zoom capability. Five predefined graphs showing key performance metrics with additional user-defined metrics available for visualization.
The new v7.4 level of microcode combines features from v7.2.7 and v7.3 into a single code base.
In previous 3-site mirroring implementations, you had A-to-B-to-C cascading. Metro Mirror would get the data from A-to-B, then Global Mirror would copy B-to-C. Multiple Target Peer-to-Peer Remote Copy (PPRC) feature number 7025 allows you to have two separate paths of the data: A-to-B and separately A-to-C. Some folks refer to this as a "star" configuration.
For System z mainframe clients, the new v7.4 introduces new zHyperWrite for DB2 database logs, enhances zGM (XRC) write pacing, and extends Easy Tier automated-tiering API to allow z/OS applications to influence placement on different tiers of storage.
The High Performance Flash Enclosures (HPFE) that IBM introduced last May for the "A" frames are now available for "B" frames. You can have four HPFE in A, and another 4 in B.
DS8870 now offers 600 GB 15K rpm SAS and 1.6 TB 2.5-inch SSD encryption drives for additional capacity and cost performance options to meet data growth demands within the same space. Both support data-at-rest encryption.
Lastly, we have upgraded the OpenStack Cinder driver to the latest Juno release, including features like volume replication and volume retype.
The latest SAN switch is a slim 1U high box that can be configured with 12 or 24 ports. These are 16Bps ports that can auto-negotiate down to 8Gbps, 4Gbps and 2Gbps. These are easy to set up, and can be managed with the IBM Network Advisor management software.
GPFS is the core technology for IBM's "Codename: Elastic Storage" initiative.
You have several options. First, you can purchase just the GPFS software itself. It runs natively on AIX, Windows and Linux, and can be extended to support other operating systems through the use of NAS protocols like NFS or CIFS. Today, the Linux support which was previously just x86 and POWER has been extended to include Linux on System z mainframes as well.
GPFS v4.1 offers "Native RAID" support, with de-clustered RAID in 8+2P and 8+3P configurations. Like the IBM XIV Storage System, this scatters the data across many drives, and can tolerate drive failures better than traditional RAID-5 configurations.
Another option is to get a pre-configured "Converged" appliance that combines servers, storage and hardware. We already offer SONAS and the Storwize V7000 Unified, but IBM now offers the "GPFS Storage Server" running on the new P822L Linux-on-Power servers, RHEL v7, and and GPFS v4.1 with Native RAID to twin-tailed attached DCS3700 expansion drawers. Since GPFS provides the RAID, no need for DCS37000 controllers, saving clients substantial costs.
The IBM Storwize family includes SAN Volume Controller, Storwize V7000, Storwize V7000 Unified, Storwize V5000, Storwize V3700 and Storwize V3500.
The big announcement is that IBM now offers data-at-rest encryption for block data on internal drives in the new generation of Storwize V7000 and V7000 Unified models. There is no performance impact, and no need to purchase new SED-capable drives.
Data-at-rest encryption helps in several ways. First, it protects data if a drive is pulled out and taken away maliciously. Second, it protects data if the drive fails and you want to send it back to the manufacturer for replacement. Third, it allows you to perform a "secure erase" so that the data can be sold or re-purposed without fear of anyone reading previous data.
Initially, the encryption key management is built-in, with the keys stored on a USB memory stick physically attached to the model. In the future, IBM will extend this support to SVC, extend this support to external virtualized drives, and extend this support to IBM Security Key Lifecycle Manager (SKLM).
Other announcements include 16Gbps adapters for SVC, Storwize V7000 and V7000 Unified. The entire Storwize family will also enjoy both 1.8TB 10K RPM 2.5-inch drives, and 6TB 7200RPM 3.5-inch drives
See the Announcement Letter (available later this month) for details.
New TS1150 enterprise tape drives
The anticipation is over! The new TS1150 tape drive has been announced, with 10TB raw un-compressed "JD" media cartridge capacity and 360 MB/sec throughput performance. The new drive is read/write compatible with TS1140 on JC, JY and JK media cartridges.
For the virtual tape libraries for the System z platform, IBM offers two models. The TS7740 had a small amount of disk front ending tape library of physical tape. The TS7720 had a large amount of disk with no tape library.
But then the person carrying the chocolate bar bumped into the person carrying the jar of peanut butter, and the rest is history. IBM will now allow tape attach on TS7720, best of both worlds! Large disk cache plus tape library attach.
Tape-attached TS7720 configurations can have up to eight partitions, with different partitions have different policies. Some might move data from disk cache to tape more aggressively, while other partitions may keep data on disk for longer periods, or indefinitely if needed.
Logical tape volumes can now be up to 25GB in size.
The DCS3700 is IBM's entry-level disk system for sequential-oriented workloads. Today, IBM announced new disk drive options: 400GB 2.5-inch SSD, 800 GB 2.5-inch SSD, and 1.2TB 10K RPM 2.5-inch drive. All of these offer T10 Protection Information (PI) data integrity.
Well, it's the end of the year, so I thought a recap of year 2014 would be in order.
The year started out with some January announcements, including the IBM FlashSystem 840. IBM is proud to be ranked #1 in All-Flash Arrays, and the IBM acquisition of Texas Memory System has caused all of the other competitors to scramble their own wanna-be offerings. IBM also announced it was going to sell off its System x division to Lenovo.
In February, I wrapped up a project to build a Linux-based PC for a kindergarten class. IBM announced some exciting new things at Pulse 2014 conference, including IBM Bluemix Platform-as-a-Service (PaaS), new IBM SmartCloud Virtual Storage Center offerings, and acquisition of Cloudant Database. Also, on Valentine's day, IBM announced the FlashSystem V840, which combines the software-defined storage features of SAN Volume Controller, with the Microlatency of the FlashSystem 840. IBM sold its 10,000th PureSystems converged expert-integrated system.
In March, I completed a six-month film project ["A Tucson Executive Briefing Center: A Quick Visual Tour"]. I was writer/director/actor for this quick 3-minute film posted on YouTube. I wrote the script and had it reviewed by a professional script reviewer, hired a professional cinemetographer, paid royalties for background music, located a voice-over expert for narration, and trained the actors (all IBM employees) how to read their lines and stand on their mark for the camera. It was a big success!
In April, I presented at the Systems Technical University in Istanbul, Turkey. I had been to Turkey before, but this was my first time to the city of Istanbul itself. The owner of my local [Savaya Coffee] is from Istanbul, and was able to introduce me to someone who was able to arrange for a full tour my first day! Meanwhile, on the other side of the pond, IBMers in New York were celebrating the 50th anniversary of the IBM mainframe, including a cameo appearance on the TV show "Mad Men".
In May, I was busy presenting at the IBM Edge conference in Las Vegas. IBM celebrated the sixth anniversary of IBM ProtecTIER data deduplication device, announced "Codename: Elastic Storage" and new features on the DS8870 disk system, and presented analyst findings that IBM Software Defined Storage was substantially less expensive than competitive offerings.
In July, I took a nice summer vacation, [a road trip across the state of Tennessee]. IBM made a strategic partnership with Apple to offer mobile apps for the data center enterprise for the iOS operating system on iPhones and iPad tablets.
In August, I completed a summer partnership with University of Toronto and IBM Softlayer to build "Concept IBM Watson", a scaled down version of IBM Watson based on my infamous 2011 blog post [How to replicate Watson hardware and systems design for your own use in your basement]. Rather than using three physical servers, however, we had virtual x86 machines running on IBM Softlayer cloud. The system was only asked the simplest "How many...?" questions against a single text document, but proved to the University that teaching analytics by replicating IBM's historic achievement was effective and possible.
In September, I celebrated my eight year "Blogoversary". That's right, I have been blogging for the past eight years! With over 800 posts, and five published books, I countinue to be ranked #1 most-read blog on IBM developerWorks. IBM was ranked #1 for Software Defined Storage!
In October, I presented at the Systems Technical University in Dublin, Ireland. This was my first time in Ireland, and I found Dublin to be quite a beautiful city, with friendly people and delicious food.
The rest of October, and much of November and December, I spent on the road, visiting clients to help close deals! (Sorry folks... Due to SEC black-out rules, I am prohibited from telling you how well I did) Since I am not allowed to talk about on-going discussions that I have with clients, my blog has been noticeably silent during these months. I apologize for any stress or anxiety this might have caused any of my readers!
Despite too-much-candy, too-much-turkey and too-many-cookies that the year-end often brings, I managed to lose twenty pounds on a low-carb, gluten-free, Paleo diet and exercise.
This month (September, 2006) marks our 50th anniversary of the disk system. The first disk system was the 350 Disk Storage Unit, designed to attach to the IBM 305 RAMAC mainframe computer, both introduced to the world in September, 1956.
"Do you know what I do?" Mr. Mondavi recalls Mr. Gallo asked him when they first met. "Yes, you run the largest winery in the country," recalls Mr. Mondavi, then in his mid-20s. "No," Ernest corrected him. "I go out and visit customers in stores."
Robert Smith (aka Radio Voom) reports on National Public Radio that Second Life is now being used for campaigning for political candidates. It used to be that political candidates took trains and buses across the country, meeting people, discussing their issues, and getting a feel for what is going on in the hearts and minds of their potential voters. With the development of TV and Radio, candidates traveled less, hoping to get their word out to people who would listen to them. Using Second Life and other social networking tools brings candidates back to having conversations with the people they hope to represent.
Of course, many of these candidates are old, and are learning internet social networking skills for the first time. John McCain, my senator from Arizona, is running for President at 70 years old! It's true that old dogs CAN learn new tricks.
IBM is investing heavily into Second Life, as are many other forward-thinking companies, to explore the age-old human need for connectedness, community and dialog. I've asked my team to all get their avatars up and running in Second Life. Granted there is a bit of a learning curve, but everybody handles change in different ways, some better than others.
"Knowledge is the antidote to fear." -Ralph Waldo Emerson
Why are most of these guys (and girls) with over a billion US dollars in net worth still working? Perhaps because they embrace new ideas, and are on the thrill seeking side of humanity. I guess I am too. I'll be thrill-seeking in Chicago this weekend, celebrating St. Patrick's day.
The weather has warmed up here in Tucson so I started my Spring Cleaning early this year and unearthed from my garage a [Bankers Box] full of floppy diskettes.
IBM invented the floppy disk back in 1971, and continued to make improvements and enhancements through the 1980s and 1990s. It will be one of the many inventions celebrated as part of IBM's Centennial (100-year) anniversary. Here is an example [T-shirt]
IBM needed a way to send out small updates and patches for microcode of devices out in client locations. IBM had drives that could write information, and sent out "read-only" drives to the customer locations to receive these updates. These were flexible plastic circles with a magnetic coating, and placed inside a square paper sleeve. Imagine a floppy disk the size of a piece of standard paper. The 8-inch floppy fit conveniently in a manila envelope, sendable by standard mail, and could hold nearly 80KB of data.
I've been using floppies for the past thirty years. Here's some of my fondest memories:
While still in high school, my friend Franz Kurath and I formed "Pearson Kurath Systems", a software development firm. We wrote computer programs to run on UNIX and Personal Computers for small businesses here in Tucson. Whenever we developed a clever piece of code, a subroutine or procedure, we would save it on a floppy disk and re-use it for our next project. We wrote in the BASIC language, and our databases were simple Comma-Separated-Variable (CSV) flat files.
The 5.25-inch floppies we used could hold 360KB, and were flexible like the 8-inch models. Later versions of these 5.25-inch floppies would be able to hold as much as 1.2MB of data. We would convert single-sided floppies into double-sided ones by cutting out a notch in the outer sleeve. Covering up the notches would mark them as read-only.
The 3.5-inch floppies were introduced with a hard plastic shell, with the selling point that you can slap on a mailing label and postage and send it "as is" without the need for a separate envelope. These new 3.5-inch floppies would carry "HD" for high density 720KB, and double-sided versions could hold 1.44MB of data. The term "diskette" was used to associate these new floppies with [hard-shelled tape cassettes]. Sliding a plastic tab would allow floppies to be marked "read-only". IBM has the patent on this clever invention.
Continuing our computer programming business in college, Franz and I took out a bank loan to buy our first Personal Computer, for over $5000 dollars USD. Until then, we had to use equipment belonging to each client. The banks we went to didn't understand why we needed a computer, and suggested we just track our expenses on traditional green-and-white ledger paper. Back then, peronsal computers were for balancing your checkbook, playing games and organizing your collection of cooking recipies. But for us, it was a production machine. A computer with both 5.25-inch and 3.5-inch drives could copy files from one format to another as needed. The boost in productivity paid for itself within months.
Apple launched its Macintosh computer in 1984, with a built-in 3.5-inch disk drive as standard equipment. Here is a YouTube video of an [astronaut ejecting a floppy disk] from an Apple computer in space.
In my senior year at the University of Arizona, my roommate Dave had borrowed my backpack to hold his lunch for a bike ride. He thought he had taken everything out, but forgot to remove my 3.5-inch floppy diskette containing files for my senior project. By the time he got back, the diskette was covered in banana pulp. I was able to rescue my data by cracking open the plastic outer shell, cleaning the flexible magnetic media in soapy water, placing it back into the plastic shell of a second diskette, and then copied the data off to a third diskette.
After graduating from college, Franz and I went our separate ways. I went to work for IBM, and Franz went to work for [Chiat/Day], the advertising agency famous for the 1984 Macintosh commercial. We still keep in touch through Facebook.
At IBM, I was given a 3270 terminal to do my job, and would not be assigned a personal computer until years later. Once I had a personal computer at home and at work, the floppy diskette became my "briefcase". I could download a file or document at work, take it home, work on it til the wee hours of the morning, and then come back the next morning with the updated effort.
To help prepare me for client visits and public speaking at conferences, IBM loaned me out to local schools to teach. This included teaching Computer Science 101 at Pima Community College. When asked by a student whether to use "disc" or "disk", I wrote a big letter "C" on the left side of the chalkboard, and a big letter "K" on the right side. If it is round, I told the students while pointing at the letter "C", like a CD-ROM or DVD, use "disc". If it has corners, pointing to corners of the letter "K", like a floppy diskette or hard disk drive, use "disk".
On one of my business trips to visit a client, we discovered the client had experienced a problem that we had just recently fixed. Normally, this would have meant cutting a Program Trouble Fix (PTF) to a 3480 tape cartridge at an IBM facility, and send it to the client by mail. Unwilling to wait, I offered to download the PTF onto a floppy diskette on my laptop, upload it from a PC connected to their systems, and apply it there. This involved a bit of REXX programming to deal with the differences between ASCII and EBCDIC character sets, but it worked, and a few hours later they were able to confirm the fix worked.
In 1998, Apple would signal the begining of the end of the floppy disk era, announcing their latest "iMac" would not come with an internal built-in floppy drive. David Adams has a great article on this titled [The iMac and the Floppy Drive: A Conspiracy Theory]. You can get external floppy drives that connect via USB, so not having an internal drive is no longer a big deal.
While teaching a Top Gun class to a mix of software and hardware sales reps, one of the students asked what a "U" was. He had noticed "2U" and "3U" next to various products and wondered what that was referring to. The "U" represents the [standard unit of measure for height of IT equipment in standard racks]. To help them visualize, I explained that a 5.25-inch floppy disk was "3U" in size, and a 3.5-inch floppy diskette was "2U". Thus, a "U" is 1.75 inches, the thinnest dimension on a two-by-four piece of lumber. Servers that were only 1U tall would be referred to as "pizza boxes" for having similar dimensions.
Every year, right around November or so, my friends and family bring me their old computers for me to wipe clean. Either I would re-load them with the latest Ubuntu Linux so that their kids could use it for homework, or I would donate it to charity. Last November, I got a computer that could not boot from a CD-ROM, forcing me to build a bootable floppy. This gave me a chance to check out the various 1-disk and 2-disk versions of Linux and other rescue disks. I also have a 3-disk set of floppies for booting OS/2 in command line mode.
So while this unexpected box of nostalgia derailed my efforts to clean out my garage this weekend, it did inspire me to try to get some of the old files off them and onto my PC hard drive. I have already retrieved some low-res photographs, some emails I sent out, and trip reports I wrote. While floppy diskettes were notorious for being unreliable, and this box of floppies has been in the heat and cold for many Arizonan summers and winters, I am amazed that I was able to read the data off most of them so far, all the way back to data written in 1989. While the data is readable, in most cases I can't render it into useful information. This brings up a few valuable lessons:
Backups are not Archives
Some of the files are in proprietary formats, such as my backups for TurboTax software. I would need a PC running a correct level of Windows operating system, and that particular software, just to restore the data. TurboTax shipped new software every year, and I don't know how forward or backward-compatible each new release was.
Another set of floppies are labeled as being in "FDBACK" format. I have no idea what these are. Each floppy has just two files, "backup.001" and "control.001", for example.
Backups are intended solely to protect against unexpected loss from broken hardware or corrupted data. If you plan to keep data as archives for long-term retention, use archive formats that will last a long time, so that you can make sense of them later.
Operating System Compatibility
Windows 7 and all of my favorite flavors of Linux are able to recognize the standard "FAT" file system that nearly all of my floppies are written in. Sadly, I have some files that were compressed under OS/2 operating system using software called "Stacker". I may have to stand up an OS/2 machine just to check out what is actually on those floppies.
You can't judge a book by its cover
Floppies were a convenient form of data interchange. Sometimes, I reused commercially-labeled floppies to hold personal files. So, just because a floppy says "America On-Line (AOL) version 2.5 Installation", I can't just toss it away. It might actually contain something else entirely. This means I need to mount each floppy to check on its actual contents.
So what will I do with the floppies I can't read, can't write, and can't format? I think I will convert them into a [retro set of coasters], to protect my new living room furniture from hot and cold beverages.
A lot of people ask me about IBM branding, as we have recently changed brands. In the past we had two separate brands, one for servers (eServer) and one for storage (TotalStorage). These would be fine if we wanted to promote their independence, but customers today want synergy between servers and storage, they want systems that work well together.
Last year, in response to market feedback, we crated a new brand, "IBM Systems" and put all the server and storage product lines under one roof. Over time, we will transition from TotalStorage to System Storage naming. This will occur with new products, and major versions of existing products.
Two other phrases you will hear in the names of our offerings are "Virtualization Engine" and "Express". These are portfolio identifiers. The Virtualization Engine identifier was created to emphasize our leadership in system virtualization, and we have products that span product lines with this identifier.
The Express identifier was created to emphasize our focus on Small and Medium sized business (SMB). It spans not just servers and storage, but across other offerings from other IBM divisions.
Of course, just renaming products and services isn't enough. Systems don't work together just because they have similar names, are covered in similar "Apple white" plastic, or have similar black bezels. Obviously, thoughtful and collaborative design are needed, with the appropriate amounts of engineering and testing. IBM is aligning its server and storage development so that the IBM Systems brand keeps its promise.
IBM's emphasis on "Information Infrastructure" is to help organizations get the right information, to the right people at the right time. This helps them to have the right insights, make the right decisions, and develop the right innovations needed for the challenges at hand.
As the planet got smaller and flatter, IBM led the way. Now, as the planet needs to get smarter--with more efficient health care, energy distribution, financial institutions, and IT infrastructures--IBM will once again take the lead.
