HP Cluster Management Utility V4.1 |
|
HP Cluster Management Utility V4.1 (CMU) is a software suite of tools
that are used to manage a large collection of nodes within a High Performance
Computing (HPC) cluster environment. Each cluster configuration includes
separate management networks using Ethernet switches. CMU makes the management
of this cluster more user friendly, efficient, and error free than if
it were being managed by scripts, or on a node-by-node basis. CMU also
offers full support for ILO2, LO100i adaptors or Integrity ILO adaptors,
where applicable on the HP servers in the cluster. |
|
|
|
|
| Interface | CMU comes with a Command Line Interface (CLI) and a full JAVA® Graphical User Interface (GUI) that can be customized. It allows access to all compute node consoles from a single screen with a single mouse click. CMU software supports HP SIM level 1 integration. Very large cluster configurations (more than 4000 nodes) are supported. |
|
|
|
| Management | From the CMU graphical user interface, you can monitor, halt, boot, reboot or power off any selection of nodes using ILO2, LO100i adaptors or Integrity ILO management functionality where applicable. Your CMU session connects to several nodes in the cluster and broadcasts commands to the selected nodes. You can also use CMU for reporting and managing cluster events, such as nodes shutting down or powering up. Using the CMU CLI, you can halt, boot, reboot or power off any selection of nodes by using the HP server management card functionality where appropriate. Group and node administration tasks like create/modify or delete are also available through CMU CLI and shell commands. This capability allows, for example, the dynamic creation of groups of nodes matching Platform LSF®, Altair PBS® Professional™ and SLURM (and other resource manager) node allocations. |
|
|
|
| Provisioning | CMU has the capability to propagate an operating
system image to all of the compute nodes in the cluster. CMU can clone,
(over the network), disk partition contents from an image server to the
local disks of the compute nodes. You use this process for first time installation
of compute nodes and also to propagate updates to the kernel or the current
system configuration. CMU automatically manages the target disk partitioning
in cases where the target partition differs from the initial image. CMU
partitions the target disk during the cloning phase, avoiding the partitioning
of each compute node during the first installation. Cloning functionality
is available from both the CMU CLI and GUI. The cloning algorithm is scalable
and achieves high efficiency through hierarchical provisioning. In addition,
CMU supports diskless cloning for Red Hat Enterprise Linux and for SUSE
Linux Enterprise Server, on up to 192 servers. As part of the cloning procedure,
CMU has a mechanism for running scripts just after the completion of cloning
and also during the cloning phase, just after net boot. This latter feature
permits, for example, the remote flashing of the bios. Aside from the cloning feature, CMU also provides the ability to use kickstart (for Red Hat) remote installation. |

|
| Monitoring | The CMU monitoring features makes it possible to see, at a glance, the state of the cluster. The cluster monitoring GUI provides a summary of each node's state and also provides a summary per group. In addition, the GUI can display, using a performance gauge, the cumulative value of any metric over the servers that are displayed. The GUI displays customizable information and also displays alerts for all nodes of the cluster. The default update timer is 5 seconds, but it should be noted that the monitoring module does not heavily burden the CPU's on the compute nodes. As an example, measurements on a 100-node cluster, showed that the monitoring feature uses about 0.01% of the CPU time on each compute node. In addition to the sensors (sometimes known as metrics) that are pre-configured with CMU, administrators can configure their own sensors. Also, a large number of lightweight sensors are provided with collectl, a popular monitoring package included with CMU. Collectl can be configured to store monitoring data for later analysis. The data can be viewed directly, and historical displays can also be viewed using the colplot software provided with CMU. Very large configurations (more than 4000 nodes) are supported through monitoring synchronization and a scalable petals display mechanism. |

|
| Availability | HP ServiceGuard can be used for the fail over of all CMU services other than cloning and backup. Support for HP ServiceGuard will be discontinued in subsequent releases of CMU. |
|
|
|
| Operating System Support | The CMU software is generally supported on
Red Hat Enterprise Linux (RHEL) Advanced Server 3, 4 and 5 and SUSE Linux
Enterprise Server (SLES) 9, 10 and 11. CMU diskless support is, however,
limited to SLES 10. Amongst the distributions supported for diskless cloning,
are RHEL 4.7, RHEL 5.3 and SLES 10 sp2. Under certain circumstances, open source Linux distribution like Debian, CentOS, Scientific Linux can be supported with HP CMU on the compute nodes. Please contact your HP sales representative for more information. |
|
|
|
| Installation |
CMU software and documentation is delivered on a single DVD-ROM that includes the software itself and all the documentation. The system administrator need only mount the DVD-ROM, read the release notes and follow the CMU installation Guide instructions to install CMU and begin crafting a cluster. |
|
|
|
| Hardware Requirements |
CMU Software is supported on each node of a valid configuration such as the HP Cluster Platform 3000/3000BL or HP cluster platform 4000/4000BL.
As new HP servers are released, the above list of CMU-supported platforms
will be augmented. Please contact your HP salesperson for more information. |
|
|
Pre-requisite Software
| The appropriate Red Hat or SUSE Linux kit must be installed on the master server before CMU Software installation. These kits can be purchased from HP. | |
| Software Licensing Information |
For the Software license to be valid on an HP Cluster, the HP Cluster
must be licensed both by CMU License (one per cluster) and CMU Compute
Node Licenses for a total quantity equal to or greater than the number
of HP ProLiant in the HP Cluster. |
|
|
|
| Electronic Software Delivery |
Electronic software is now available in most countries. HP recommends purchasing electronic products over physical products when available for faster delivery and the convenience of not having to manage-either file away or throw away-confidential paper licenses. For more information, please contact an HP representative. |
|
|
|
| License Management Facility Support |
CMU supports the FlexLM license management facility. The FlexLM license key is provided upon presentation of a valid license key request form. This form is delivered with the software license (see the Ordering Information section of these QuickSpecs). For more information about installing the CMU license keys, refer to the CMU documentation. |

| Software and Services Warranty |
The only warranties for HP products and services are set forth in the express warranty statements accompanying such products and services.
HP provides third-party products, software, and services that are not HP Branded "AS IS" without warranties of any kind, although the original manufacturers or third party suppliers of such products, software and services may provide their own warranties. |

Ordering Information
| CMU products are ordered by HP
order administrators, using either of two ordering formats. With the latter
format, fixed Care Pack services are available in additional to other contractual
services (see the section on Software Product Services. Each server in an
HP Cluster, except for the management node, must be licensed by a CMU Compute
Node License (BA664A or 436284-B21 or TC297AAE). The management node must
be licensed by the license which comes with the product CMU License and
Media (BA666A or 433257-B21). ). In addition, if the management node will
also be managed by CMU as a compute node, an additional CMU Compute Node
License will be required. NOTE: Electronic software (TC297AAE) is available in all countries except China and Japan. For China and Japan should order the physical equivalent. |
