Just wanted to let you know that there is technical overview paper and a great step-by-step “lab” document available from Novell’s website which describes how to set up a lab environment with four exciting (and included, supported) features within SUSE Linux Enterprise Server 10:

  • iSCSI
  • Oracle Clustered File System (OCFS) v2
  • Heartbeat v2 – cluster service
  • Enterprise Volume Management Service (EVMS)

These features are collectively known as the High Availability Storage Infrastructure (HASI) and provides an out-of-the-box capability to implement a fully clustered storage system. You don’t have to pay for clustering as a “premium” services with SUSE Linux Enterprise Server (SLES) 10.

The document gives you step-by-step instructions that will allow you to get your hands dirty and try this out. You can even combine HASI with the Xen virtualization capabilities to implement a live migration of a virtual machine from one physical server to another… similar to VMotion — but again, included with the base OS, SLES 10.

If you’re interested, I also found this “lighter weight” how-to article at SearchEnterpriseLinux.com which talks about how to setup Heartbeat clustering on SLES 10.
