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.
Hello everyone! I am back, fully well-rested from a wonderful 3-week vacation touring the lovely state of Tennessee. Here's a quick recap:
(FCC Disclosure: I mention various companies and products in this blog post. I have no financial interested in any of them, nor have I received any compensation to mention or endorse them here.)
Our first stop was Lynchburg, TN, home of [Jack Daniel's], America's oldest whiskey distillery. Our tour guide, Ron (who both looked and sounded like [John Goodman]) took us first to see how they burn wood to make charcoal, then the natural water spring which supplies the iron-free water used for the whiskey. We then got a whiff of the mash at various stages of fermentation. Lastly, we had samples of Original No. 7, Gentleman's Jack, and Single Barrel.
(A word of caution: Domestic airlines only allow FIVE LITERS of Bourbon, Whiskey or Rum in your checked luggage. That is only six bottles at the 750ml size, of beverages that are between 24 to 70 percent alcohol by volume [ABV]. Anything above 70 percent is considered too flammable to take on the plane. Excess bottles can be custom packed and shipped, but can be quite expensive. Nearly everyone we met drove all the way to Tennessee instead of flying, and now I understand why.)
While in the area, we had a nice lunch at [Miss Mary Bobo's], a boarding house turned into a restaurant. They only serve one meal a day at 1pm, by reservation only. And we were paired up with eight others and served food "family style" a large round table with a [Lazy Susan].
Jack Daniel's is not the only attraction in the area. We also visited [Falls Mill], a grist mill that grinds corn, wheat and rye for the other distilleries. Mo and I visited [Prichard's Distillery], where they make Whiskey, Rye and Rum. We highly recommend their molasses-flavored "Sweet Lucy"!
We stopped at the famous historic landmark, the [Chattanooga Choo Choo], which was formerly a train station, and now renovated into a hotel. We asked to see the inside of one of the train cars converted into a hotel room.
Gatlinburg and Pigeon Forge
We stayed in a cabin in the [Smokey Mountains] near Gatlinburg. In addition to pleasant rides through the National park, we also walked around the small town, looking at all the shops and amusements.
The next town over is Pigeon Forge, and driving down the main parkway is like Las Vegas in a slightly alternate universe. One person called it the Redneck Riviera!
We spent two days at Dollywood theme park, named after its founder, famous country singer Dolly Parton. We arrived after 3pm the first day, so they gave us the second day free!
In addition to roller coaster rides, artisan shops and restaurants, we found zip lines! Mo and I put on harness, attached to a pulley, and zipped over roller coasters, trees and rivers throughout Dollywood park. It was a lot of fun!
We also went to Dolly Parton's other attraction: Stampede. This was a dinner show with horses. It was similar to the Excalibur show we saw in Las Vegas last year during the week of Edge 2013 Conference.
On our way from Gatlinburg, we stopped into Knoxville to have lunch with clients. We had a choice to make, we could either drive up into Kentucky and visit the distilleries in the Bourbon trail, or drive straight to Nashville and spend more time there. We opted for Nashville, saving the Bourbon trail for a future trip.
Our final stop was Nashville, known as Music City. Our hotel was on Broadway, walking distance between Vanderbilt University and the [honky-tonks] downtown.
We had purchased advanced tickets for the [Grand Ole Opry]. This is not your typical concert. Instead, you have no idea who will play until just a few days before. The three hour show had about a dozen different musical acts, some famous, some new to the country music scene.
We went to the Johnny Cash Museum. People with ticket stubs from the Grand Ole Opry get in for a discount!
Searching [TripAdvisor] for things to do in Nashville, I found [The Escape Game]. You pay them money to lock you up in a room with a bunch of strangers, and then collectively as a team you need to figure out how to escape by solving puzzles and clues.
Each room has different themes. First, we tried the "Underground Playground". You know that TV show [Are you Smarter than a Fifth Grader?] Well, the majority of our so-called team were not in this case, and after 60 minutes the referee told us we had failed and unlocked the door.
We had so much fun that we came back two days later to try a different room. This time we tried "The Heist" which is all about art theft. The strangers we were teamed up with were very motivated to get out of the room in time, and we succeeded, getting out in just 54 minutes!
Mo and I had a great time, but are glad to be back home!
Well, it's Tuesday again, and you know what that means? IBM Announcements!
Back in 2007, my blog post [Double Happy Wedding] compared IBM's acquisition for a company that produced data migration software to the practice in Japan of waiting until the bride is five to seven months pregnant to have a wedding. In USA, these are called "shotgun" weddings.
I was in Japan when I wrote that, and the company IBM acquired was Japanese, so the comparison stuck.
Today, IBM announces the latest versions Transparent Data Migration Facility z/OS v5 [TDMF] and z/OS Dataset Migration Facility v3 [zDMF] software products.
(Where better to commemorate this event than in Pigeon Forge, Tenessee, the capital of shotgun wedding venues! Including, and I am not making this up, a replica of the [grand staircase of the Titanic]. Yes, you can book this for a shotgun wedding, while your guests re-arrange the deck chairs. I stopped at a local McDonald's to submit this blog post.)
TDMF software allows you to migrate CKD volumes that are attached to your System z mainframe, including those that are actively being used by applications. zDMF allows you to migrate z/OS data sets, including those currently open by applications.
The migration is hardware-agnostic, supporting CKD volumes on IBM, EMC and HDS disk systems. As many clients are migrating from EMC and HDS disk systems to IBM DS8870, this is a good time to look at TDMF and zDMF to help make the process as transparent as possible.
Of course, if you are not interested in acquiring the software to do this yourself, you can hire IBM Data Mobility Services, which uses TDMF and zDMF to do it for you!
Over time, I have gotten many emails, comments and tweets related to this post. The instructions have been downloaded over 130,000 times!
The letter below was so inspiring that I felt I need to share it. (Published here with permission from the author, who goes by the screen name DaveAlex)
Thought you would like to know that I am working toward an AI Agent hopefully more advanced than "Watson Jr." although I will probably include the software behind it.
The hardware I have on hand is a System X3650M2 which I bought for $250 on eBay. It has four 2.66 GHz Xeons with 6 cores each, and 16 GB RAM. I have another 16 to install when I need it. I will shortly have 4 TB of HDD space on line, plus an addition 3 TB USB3 drive.
Ultimately, I hope to have some of the available knowledge bases on line, Freebase, CYC, etc which will handle specific information perhaps better than the Watson software by itself.
What the target (goal) that I am aiming for is a stationary version of Commander Data of Star Trek, Next generation.
I envision if having some form of self knowledge, being capable of processing graphical data, i.e., facial recognition, gesture interpretation, voice input/output, mathematical processing, with graphical output (display & hardcopy) and several additional features.
As I have studied this project, I am amazed at how much of the required software is already available. The biggest stumbling block is integrating the separate parts.
Back to Hardware. I just bought 2 Dell 2850 servers, each with dual Intel Xeons which can handle some of the tasks. If I need more processing power, I just happen to have about 10 other towers with Pentium IV or dual core processors sitting around, which can be pressed into service as needed. So far, my total cost is less than $1000 US Dollars, and my wife has not thrown me out yet. I continue to watch eBay for additional older used equipment for fractions of the original cost. My friends who follow my project keep telling me that I need to get on with the software, and add hardware as needed; they are absolutely correct, but I can't resist a bargain.
The power consumption is a potential problem, but I have a 4500 Watt solar array to use. The cooling could be a problem too, but my house sits into the side of hill, and can readily duct the air supply pass the sub-surface wall, perhaps with old Processor cooling fins glued to the wall.
I hope to get some hobby programmers involved in the project, it is a bit beyond my programming capabilities. I hope that I can live long enough to see it come to fruition; I am 78 now, and mentally in very good condition.
Wow! He is 78 years old! While others his age are playing shuffleboard at the nursing home, he is out there learning new things about the latest technology. I wish him the best of luck on this! If you would like to reach out to DaveAlex, send me a note or comment below, and I will forward them on to him.
