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,
Well, it's Wednesday, and you know what that means... IBM Announcements!
(Actually most IBM announcements are on Tuesdays, but IBM gave me extra time to recover from my trip to Europe!)
Today, IBM announced [IBM PureSystems], a new family of expert-integrated systems that combine storage, servers, networking, and software, based on IBM's decades of experience in the IT industry. You can register for the [Launch Event] today (April 11) at 2pm EDT, and download the companion "Integrated Expertise" event app for Apple, Android or Blackberry smartphones.
(If you are thinking, "Hey, wait a minute, hasn't this been done before?" you are not alone. Yes, IBM introduced the System/360 back in 1964, and the AS/400 back in 1988, so today's announcement is on scheduled for this 24-year cycle. Based on IBM's past success in this area, others have followed, most recently, Oracle, HP and Cisco.)
Initially, there are two offerings:
IBM PureFlex™ System
IBM PureFlex is like IaaS-in-a-box, allowing you to manage the system as a pool of virtual resources. It can be used for private cloud deployments, hybrid cloud deployments, or by service providers to offer public cloud solutions. IBM drinks its own champagne, and will have no problem integrating these into its [IBM SmartCloud] offerings.
To simplify ordering, the IBM PureFlex comes in three tee-shirt sizes: Express, Standard and Enterprise.
IBM PureFlex is based on a 10U-high, 19-inch wide, standard rack-mountable chassis that holds 14 bays, organized in a 7 by 2 matrix. Unlike BladeCenter where blades are inserted vertically, the IBM PureFlex nodes are horizontal. Some of the nodes take up a single bay (half-wide), but a few are full-wide, take up two bays, the full 19-inch width of the chassis. Compute and storage snap in the front, while power supplies, fans, and networking snap in the back. You can fit up to four chassis in a standard 42U rack.
Unlike competitive offerings, IBM does not limit you to x86 architectures. Both x86 and POWER-based compute nodes can be mixed into a single chassis. Out of the box, the IBM PureFlex supports four operating systems (AIX, IBM i, Linux and Windows), four server hypervisors (Hyper-V, Linux KVM, PowerVM, and VMware), and two storage hypervisors (SAN Volume Controller and Storwize V7000).
There are a variety of storage options for this. IBM will offer SSD and HDD inside the compute nodes themselves, direct-attached storage nodes, and an integrated version of the Storwize V7000 disk system. Of course, every IBM System Storage product is supported as external storage. Since Storwize V7000 and SAN Volume Controller support external virtualization, many non-IBM devices will be supported automatically as well.
Networking is also optimized, with options for 10Gb and 40Gb Ethernet/FCoE, 40Gb and 56Gb Infiniband, 8Gbps and 16Gbps Fibre Channel. Much of the networking traffic can be handled within the chassis, to minimize traffic on external switches and directors.
For management, IBM offers the Flex System Manager, that allows you to manage all the resources from a single pane of glass. The goal is to greatly simplify the IT lifecycle experience of procurement, installation, deployment and maintenance.
IBM PureApplication™ System
IBM PureApplication is like PaaS-in-a-box. Based on the IBM PureFlex infrastructure, the IBM PureApplication adds additional software layers focused on transactional web, business logic, and database workloads. Initially, it will offer two platforms: Linux platform based on x86 processors, Linux KVM and Red Hat Enterprise Linux (RHEL); and a UNIX platform based on POWER7 processors, PowerVM and AIX operating system. It will be offered in four tee-shirt sizes (small, medium, large and extra large).
In addition to having IBM's middleware like DB2 and WebSphere optimized for this platform, over 600 companies will announce this week that they will support and participate in the IBM PureSystems ecosystem as well. Already, there are 150 "Patterns of Expertise" ready to deploy from IBM PureSystem Centre, a kind of a "data center app store", borrowing an idea used today with smartphones.
By packaging applications in this manner, workloads can easily shift between private, hybrid and public clouds.
