Key Features

Flexible, policy-driven clustering and continuous data replication—boost flexibility while improving service availability and resource utilization by supporting the mixed clustering of both physical and virtual Linux servers. Protect workloads across globally distributed data centers.

Setup, administration, management and monitoring—save time by easily managing clustered Linux servers with a powerful unified interface to quickly and easily install, configure and manage clusters, plus a simple, user-friendly tool for monitoring the clustered environment.

Continuous data replication across cluster servers in data centers anywhere in the world and minimize data loss due to corruption or failure by protecting your data assets using your existing IT infrastructure.

Cluster-aware file system and volume management for optimized performance.

Virtualization aware for managing virtual clusters as well as physical clusters.

Tech Specs

Recommendations for specific uses

  • 512 MB to 4 GB RAM, at least 256 MB per CPU
  • 44 GB hard disk space, 16 GB for snapshot/rollback of the OS
  • Network interface (ethernet, wireless or modem)
  • Network redundancy
  • I/O fencing mechanism and possibly shared storage
  • For Xen virtual host server, at least 512 MB RAM for each virtual host server
  • For KVM virtual host server, KVM's limits are equal to those of SUSE Linux Enterprise Server
  • For Xen or KVM virtual machines, at least an additional 256 MB RAM for each virtual machine

  • For print servers, a relatively faster processor or additional processors to improve server-based printing
  • For web servers, additional RAM to improve caching, and additional processors to improve web application performance
  • For database servers, additional RAM to improve caching, and using multiple disks for parallel I/O
  • For file servers, additional memory and disks, or a Redundant Array of Inexpensive Disks (RAID) system to improve I/O throughput

Minimum Linux server system requirements

  • Local installation: 512 MB RAM, 512 MB Swap recommended
  • 2 GB available disk space (more recommended, 8.5 GB for all patterns)
  • 16 GB for snapshot/rollback of the OS
