High Availability Cluster Multiprocessing (HACMP)
HACMP™ has been IBM's flagship high availability product for AIX and Linux applications for over 12 years and 12,000 clients. HACMP monitors entire systems—from the network through the hardware, operating system and application software—and quickly restarts applications on designated backup hardware in the event of a failure or performance degradation. HACMP also enables scheduled maintenance without service interruption. The optional HACMP/XD (Extended Distance) component adds remote data mirroring and failover capabilities, extending HACMP across multiple sites to protect against site-wide disasters such as power failures, floods etc. |

IBM Director
Director, IBM's proven cross-platform systems management product, has been enhanced to support System p and will be available to all System p clients at no additional charge. Director is designed to reduce the cost and complexity of systems management by providing comprehensive administration of the entire environment from a single, simple graphical interface that displays detailed information about the environment.
Features include hardware control to stop, start or reset machines remotely; software distribution to deploy new applications or updates across the environment; monitoring of critical resources with automated alerting or responses to pre-defined conditions; and process management to start, stop, schedule and monitor tasks. Furthermore, management by group reduces errors and omissions and Director can even build and maintain the groups automatically based on system characteristics. Director supports AIX, Linux and Windows® across most IBM System p, System p5 and eServer p5 platforms.

General Parallel File System (GPFS)
GPFS™ is a parallel file system that provides reliable, high-speed shared data access between a cluster of compute nodes and a set of disks. By dividing individual files into blocks and reading/writing these blocks in parallel across multiple disks, GPFS provides very high bandwidth. In addition, GPFS's multiple data paths are designed to eliminate single points of failure, making GPFS extremely reliable. Already powering many of the world's most powerful scientific supercomputers, GPFS is also commonly used in many high-bandwidth commercial applications such as digital media, financial analysis, business intelligence, petrochemical research, medical imaging and so forth. GPFS supports AIX, Linux and mixed clusters. |

Cluster Systems Management (CSM)
CSM is designed to minimize the cost and complexity of administering clustered and partitioned systems by enabling comprehensive management and monitoring of the entire environment from a single point of control. CSM provides:
- Software distribution, installation and update (operating system and applications)
- Comprehensive system monitoring with customizable automated responses
- Distributed command execution
- Hardware control
- Diagnostic tools
- Management by group
- Both a graphical interface and a fully scriptable command line interface
In addition to providing all the key functions for administration and maintenance of distributed systems, CSM is designed to deliver the parallel execution required to manage clustered computing environments effectively. CSM supports homogeneous or mixed environments of IBM servers running the AIX or Linux operating environments. |

LoadLeveler
LoadLeveler® is a job scheduler designed to maximize resource utilization and throughput in a cluster environment to get the most out of the resources. LoadLeveler schedules serial or parallel jobs based on priority, resource requirements and user-defined rules and provides fine-grained control over machine use and availability. LoadLeveler also provides detailed accounting of resource use for audit or chargeback and offers advanced functions such as checkpoint/restart to suspend and restart a job and backfill scheduling to reduce resource idle time. |
