Well, it's Tuesday again, and you know what that means! IBM announcements!
Today, I am in New York visiting clients. The weather is a lot nicer than I expected. Here is a picture of the Hudson River through some trees with leaves turning color. Something we don't see in Tucson! Our cactus and pine trees stay green year-round!
The announcements today center around the IBM PureSystems family of expert integrated systems. The PureFlex is based on Flex System components. The Flex System chassis is 10U high that hold 14 bays, consisting of 7 rows by 2 columns. Computer and Storage nodes fit in the front, and switches, fans and power supplies in the back. Here is a quick recap:
- IBM Flex System Compute Nodes
The x220 Compute Node is a single-bay low-power 2-socket x86 server. The x440 Compute Node is a powerful double-bay (1 row, 2 columns). The p260 Compute Node is a single-bay server based on the latest POWER7+ CPU processor.
- IBM Flex System Expansion Nodes
Do you remember those old movies where a motorcycle would have a sidecar that could hold another passenger, or extra cargo? IBM introduces "Expansion Nodes" for the x200 series single-bay Compute nodes. The idea here is that in a single column, you have one bay for the Compute node, and then on the side in the next bay (same column) you have an Expanions node. There are two choices:
- Storage Expansion Node allows you to have eight additional drives
- PCIe Expansion Node allows to to have four PCIe cards, which could include the SSD-based PCIe cards from IBM's recent acquisition, Texas Memory Systems.
There are times where one or two internal drives are just not enough storage for a single server, and these expanion nodes could just be the perfect solution for some use cases.
- IBM Flex System V7000 Storage Node
I saved the best for last! The Flex System V7000 Storage Node is basically the IBM Storwize V7000 repackaged to fit into the Flex System chassis. This means that in the front of the chassis, the Flex System V7000 takes up four bays (2 rows by 2 columns). In the back of the chassis are the power supplies, fans and switches.
The new Flex System V7000 supports everything the Storwize V7000 does except the upgrade to "Unified" through file modules. For those who want to have Storwize V7000 Unified in their PureFlex systems, IBM will continue to offer the outside-the-chassis original Storwize V7000 that can have two file modules added for NFS, CIFS, HTTPS, FTP and SCP protocol support.
- IBM Flex System Converged Network Switch
The Converged Network Switch provide Fibre Channel over Ethernet (FCoE) directly from the chassis. This eliminates the need for a separate "Top-of-Rack" switch, and allows the new Flex System V7000 Storage Node to externally virtualize FCoE-based disk arrays.
- Patterns of Expertise for Infrastructure
The original patterns of expertise focused on the PureApplication Systems. Now IBM has added some for the Infrastructure on PureFlex systems.
IBM has sold over 1,000 Flex System and PureFlex systems, across 40 different countries around the world, since their introduction a few months ago in April! These latest enhancements will help solidify IBM's industry leadership,
