Description

CSM V1.6 is designed to offer simple, low-cost management of distributed and clustered System p and System x servers. For organizations with both AIX 5L and Linux applications, a single CSM management console running on the AIX 5L or Linux operating system can provide management services to AIX 5L and Linux clients in distributed and clustered configurations. CSM is also a key element of the Cluster 1600 and Cluster 1350 — platforms that are ideal for workload consolidation or for achieving high degrees of scalability and performance for applications that take advantage of clustered systems architectures. Primary examples are computational modeling in HPC or multi-terabyte data warehouses in large corporations.

The CSM licensed products include:

  • CSM for AIX 5L
  • CSM for Linux on POWER
  • CSM for Linux Multiplatform (System x, BladeCenter)

New with CSM 1.6

New hardware support:

  • System p servers: p5 505Q, 590, and 595 with CSM for AIX 5L and for Linux on POWER
  • System x servers: x3455, x3550, x3650, x3850, and xSeries 366
  • AMD Opteron LS21 and LS41 for BladeCenter
  • Intel HS21 for BladeCenter

New Linux Distribution support:

  • SLES 10 support for System p and System x servers

Diskless node support: Support has been added for diskless Linux nodes in environments where the management server and diskless managed nodes are of the same Linux distribution without the use of installation servers. This support requires Warewulf and associated open source software (refer to the Software requirements section).

Support for HMC-less environments: Hardware control, remote console, and installation support has been added for LPARs managed by Integrated Virtualization Manager (IVM). IVM comes embedded within the optional Advanced POWER Virtualization feature and eliminates the need for a dedicated HMC. The IVM is included with Virtual I/O Server V1.3.

Service Focal Point (SFP) diagnostic support for POWER5: Support has been added for CSM monitoring to be able to receive events from SFP on POWER5 systems utilizing the Problem Analysis framework.

Hierarchical management servers: Support has been added to use CSM in a hierarchical structure. Hierarchical CSM is a method of using CSM in which multiple CSM management servers (and their clusters) can be installed, set up, and monitored by a single top-level management server. This can be useful to manage more nodes than the current CSM scaling limit or to divide nodes up between different departments or sets of users. Hierarchical CSM is intended for advanced CSM users.

Support for Linux upgrades: Linux OS node upgrades can now be done without requiring a full node reinstallation. Support includes only SLES service pack upgrades and RHEL release upgrades.

Enhanced monitoring support for IBM System Blue Gene Solution: Support has been added for "rearm" event monitoring to complement the event monitoring capabilities provided in the earlier release. This release also delivers new predefined conditions and sensors for Blue Gene monitoring, and improves the old ones. The enhanced support allows more flexibility in the data delivered within the Blue Gene event and rearm event notifications. IBM System Blue Gene can be monitored from any type of CSM server.

Hardware control enhancements:

  • Changes were made to the rconsole function to perform automatic logging of all console output. This allows catching of critical server failure data, which is only written to the console.
  • Improvements were made to the hwsda and lshwinfo commands.

Deployment enhancements:

  • The "getadapters" command has been enhanced to support the use of Address Resolution Protocol and SNMP in obtaining a node's MAC address.
  • CSM can now update drivers on PPC64 installations.
  • Enhanced support for minimally managed nodes includes use of CSM Configuration File Manager (CFM) and Software Maintenance System (SMS) functions. CSM will automatically run these functions when a MinManaged node is installed. Users can now manually run CFM and SMS commands for MinManaged nodes at any time.

Enhanced HPC solution packs: csm.gpfs, csm.ll, csm.pe, csm.essl, and csm.pessl solution packs have been enhanced to work with later versions of the licensed products. A csm.pe solution pack has also been added for Linux.

Usability improvements:

  • Enhanced support for CSM Highly Available Management Server (HA MS) to recover the active CSM management server when problems occur
  • Enhanced Configuration File Manager support to allow the administrator to choose either the rdist or rsync remote file distribution client to distribute files to the nodes

CSM continues to provide full interoperability of all CSM-supported combinations of CSM-supported hardware and CSM-supported operating systems. Any of the following can manage or be managed by any of the following:

  • CSM-supported System p machines running a CSM-supported version of AIX 5L
  • CSM-supported System p machines running a CSM-supported version of RHEL
  • CSM-supported System p machines running a CSM-supported version of SLES
  • CSM-supported System x machines running a CSM-supported version of RHEL
  • CSM-supported System x machines running a CSM-supported version of SLES

Note: CSM V1.6 is the last release that will support a pause of HA MS. The stop function of HA MS will be able to be used as an alternative.

Notes

  • CSM V1.6 is the last release of CSM that will support the -d flag of the cfmupdatenode command.
  • CSM V1.6 is the last release of CSM that will support AIX 5L V5.2.

High Availability Management Server (HA MS):

On all platforms, the optional CSM HA MS is designed to prevent the management server from being a single point of failure in the CSM cluster. CSM HA MS is designed to automate failover in response to failure conditions. You can also define pre- and post-scripts to customize the failover, allowing you to failover the management server, or other subsystems or data, as needed.

A new recovery command is available for the CSM HA MS to help recover the active CSM management server when problems occur.

Product positioning

CSM offers a way to manage a collection of AIX or Linux servers (nodes), either clustered or distributed, from a single point of control.

Why should you use CSM?

  • May help reduce system management costs
  • May help consolidate workloads
  • May help reduce complexity
  • May help improve asset utilization
  • May help lower total cost of ownership

Functions include automated setup, hardware control, monitoring, and configuration file management. Administrators can manage individual nodes, run commands across nodes or groups of nodes, monitor system resources, and run automated responses to events. CSM is designed to exploit the advanced hardware management features of the servers in the Cluster 1600 or Cluster 1350, or a cluster of System p or System x servers.

CSM is aimed at customers who want robust cluster systems management on an AIX 5L or open, Intel processor-based server platform. CSM and the IBM Cluster 1600 or Cluster 1350 are ideal for high-performance and commercial computing workloads, including applications in scientific and technical computing, life sciences, and On Demand Business infrastructure (for example, Web serving and collaboration/e-mail). CSM includes technology derived from IBM Parallel System Support Programs for AIX.

CSM delivers a robust, scalable management platform to help make administration easier. It may help reduce life cycle costs and can be used to manage AIX 5L or Linux servers from a central location, rather than having to manage each system individually.

Using CSM, you can scale systems incrementally as workload demand increases, without increasing the management complexity.

Adopting the Linux operating system in a production environment is more attractive when it is backed by superior management software.

CSM HA MS is positioned for enterprises that need a highly available management server. CSM HA MS is designed to remove the management server as a single point of failure in the cluster.

Ordering Information

This announcement does not include any new or changed billing or priced feature numbers or part numbers.

Note: Ordering and billing is per physical processor, regardless of processor sharing ("sub-cpu LPARs"). A processor shared among multiple partitions counts as one processor.

New customers need to order the applicable 5765-F67, 5765-G16, or 5765-E88 CSM billing feature, and applicable 5692-A5L or 5692-LOP SPO media feature number or Passport Advantage® media part number.

Contact your IBM representative for the full range of billing options.

Existing customers of CSM with active SWMA contracts are entitled to receive CSM V1.6 at no charge. Acquisition of CSM V1.6 via SWMA does not change existing SWMA contract start or end dates. Existing customers of CSM should refresh their CSM media supply, and may use their existing license key file.
