Well, it's Tuesday again, and you know what that means? IBM Announcements!
This week we also have [Valentine's day], so it is perfect time for you to fall in love with the new [IBM FlashSystem V840 Enterprise Performance Solution]! The "V" stands for Valentine.
From the photo, the marketing people staggered the various components to give it a stylized [Dagwood Sandwich] effect. I can assure you that these are just standard 19-inch rack components that fit into 6U of space in standard IT racks.
Starting top to bottom, we have the first FlashSystem V840 Control Enclosure, its 1U-high UPS, a second FlashSystem V840 Control Enclosure and its UPS, and finally a 2U-high FlashSystem V840 Storage Enclosure.
You can have up to a dozen Flash modules, either 2TB or 4TB size, for a maximum of 40TB usable RAID-protected capacity. These can be protected with AES 256-bit encryption. The FlashSystem modules are front-loaded, and slide in and out for easy maintenance.
The system is fully redundant and hot-swappable with concurrent code load to ensure high availability.
(Update: In the comments, readers thought that this was nothing more than just a two-node SVC with FlashSystem 840. There are differences, so I have added the following table.)
The system is fully VMware-certified, supporting VAAI interfaces, and an SRA for VMware's Site Recovery Manager (SRM). With Real-time Compression, you can get up to 80 percent capacity savings for workloads like Virtual Desktop Infrastructure (VDI). That in effect gives you up to 5x (200TB) of virtual capacity in 6U of rack space!
You can either keep it as an All-Flash array, or you can virtualize external IBM and non-IBM disk systems, and use the Flash capacity in the Storage Enclosure for IBM's Easy Tier automated sub-volume tiering and data migration. With or without external storage, the FlashSystem V840 can provide local and remote mirroring and point-in-time copies.
Continuing my series on building a Desktop computer for a kindergarten class, I look at three other Linux systems mentioned in the article [Top 6 Linux Distributions for Children (Ages 2 and Up)].
(This series started with my post [Kindergarten desktop - The Challenge]. I have a 512MB RAM system with 40GB disk drive that I will install Linux and educational software for a class full of kindergarten children.
First, I re-partitioned the 40GB hard drive as follows. On the extended partition, sda5 will hold my system utilities, like Clonezilla and SystemRescue, and sda6 is my swap space. This gives me three primary partitions to install three flavors of Linux to try out.
The first was [LinuxKidX], which actually started out as a Portuguese-language effort in Brazil. It was then translated to the English language to extend its reach. It is based on the KDE desktop familiar to users of OpenSUSE Linux.
Many of the education software were similar or the same as those from Edubuntu I mentioned in my last post. However, not everything was translated, and unless you are able to read Portuguese, you may not want this one.
Next, I wanted to look at [Qimo for Kids], but first I had to look for the distribution, as the mirrors listed seemed to be unavailable. I was able to find an qimo
Unlike Edubuntu, Qimo fits on a CD-ROM for older PCs that may not have DVD drives. Based on lightweight XFCE desktop, the LiveCD runs comfortably in 512MB, with a kid-friendly app launcher at the bottom of the screen. However, Qimo 2.0 is based on Ubuntu 10.04 (Lucid Lynx) LTS, with long term support expiring this May 2013. The Firefox 3.6.3 was too old to run Gmail.
Why hasn't Qimo been enhanced since 2010? It looks like you can just install the packages qimo-session and qimo-wallpaper on newer levels of Ubuntu.
Third, I tried Foresight Linux for Kids 1.0 release. The most recent Foresight is 2.5.3, but Linux for Kids is still at the 1.0 level. The "installer" was very outdated, so the website suggested following the [power-user install HOWTO].
The HOWTO can be a bit intimidating, but I was able to install just fine in 512MB of RAM. Foresight detected I had pre-configured a swap space, and used that to help finish the install process.
Like the others, it had many of the same educational software as before. A key difference is the [Conary package management]. Most systems use either Debian (DEB) or Redhat Package Manager (RPM), but this one is different, and the use of Conary may reduce the number of software applications available.
So what have I learned from these?
If you have had any experience with any of these three distros, please comment below.
Well, it's Thursday again, and you know what that means? IBM Announcements!
(OK, OK, my long-time readers already know that [storage announcements are usually on Tuesdays], not Thursdays.
Here, then, is a quick review of the storage portion of today's announcements.
In other news, IBM had once again filed [the most U.S. Patents for the 21st year in a row], and our brothers and sisters over in server land introduced [the X6 architecture for x86 servers] for the System x and PureSystems product lines, optimized for Cloud and Analytics.

Last week, in my post [IT Support for the Holidays], I mentioned that I was scrubbing computers in preparation to give them to charity. A local reader asked if I would be willing to donate one of the computers to her kindergarten class. She teaches a class of 20 kids, at the very same elementary school that I went to when I was that age.
So here is the beefiest machine of the set.
Make/Model: Sony PCV-RC850 Processor: 2.4GHz Intel 32-bit RAM: 512MB Hard disk: 40GB Removable media: CD/DVD-ROM and CD/DVD-RW Keyboard/mouse: standard PS/2 Sound: headphone jack Ethernet port: 100Mbps USB ports: two
IBM likes grand challenges, like [Deep Blue computer] to play chess against Grandmaster Garry Kasparov, and the [Watson computer] to play against two experts on the game show Jeopardy! My "Kidergarten Desktop" challenge is certainly on a smaller scale--to install software on this machine that will neet the following requirements
The 512MB is not enough to run Microsoft Windows 7, but certainly enough to run some flavors of Linux. Inspired by this review of [Top 6 Linux Distributions for Children], I thought I would give a few a spin.
Many of these have Live
I had already scrubbed the [Windows XP] and replaced with [Linux Mint 12 LXDE]. Can I just install the Edubuntu-desktop on Linux Mint? While Linux Mint is Ubuntu-based, it is not binary compatible, so I will need to install fresh.
The [Edubuntu] LiveDVD requires 1GB of memory to try out, so to get this installed, I used the "Alternate Ubuntu 12.04" installer DVD.
Why 12.04 release of Ubuntu? The current release is 13.10 will only be supported for 9 months, and in keeping with "Requirement #3 Minimal Maintenance", the [Edubuntu team recommends installing a Long Term Support (LTS) release], and 12.04.3 is the most recent LTS that will be supported through 2017.
Edubuntu recommends 20GB of disk space to run, so I have partitioned the 40GB drive as follows:
For this machine, I will have three users configured:
Ubuntu's [Alternate Installer] uses basic graphic mode that can run in 512MB, and once installed, I was then able to install the Edubuntu Desktop and both preschool and primary-level educational software, to account for all learning ability levels of the children.
admin-$ sudo bash admin-# apt-get install edubuntu-desktop admin-# apt-get install ubun
I am not a big fan of Ubuntu's "Unity" panel on the left, and was hoping that Edubuntu-desktop would remove it, but no luck. so I removed it manually.
This system does not boot USB files natively, and getting Grub2 boot loader to boot ISO files was more difficult than I imagined. I was able to extract the necessary files over to sda2 hard disk to get them to work. I took "Clonezilla" full system backups to a separate SSH server over my local subnet.
Well, that's my start. Any suggestions? Has anyone done this before? Please enter comments below.
Happy new year, everyone!
