VMWARE ESX
The document discusses the benefits of using Veritas Cluster Server (VCS) 5 for VMware ESX Server. VCS 5 provides high availability and disaster recovery for virtual machines and applications. It protects against failures at all levels from physical servers to individual applications. VCS 5 also provides granular management of virtual environments similar to physical servers and allows configurations such as M+N clusters across multiple data centers for disaster recovery.

Editor's Notes
- #5 First, vulnerability. How can we resolve this concern?
- #22 Fire Drill splits BCV snaps at remote site, mounts the BCV, then starts the SG on the mount Requires SF 5.0: BCV of a VM diskgroup will create 2 identical diskgroups; SF 5.0 renames the DG on the BCV’s so VM can import them Fire Drill SGs are isolated from production SGs, ensuring no production impact Prevents concurrency violation Walkthrough Setup: VCS HA/DR running as normal Click 1: Initiate Fire Drill. The Fire Drill Agent takes a snapshot of the replicated data (Business Continuity Volume). Click 2: Mount Snapshot. Fire Drill modifies the snapshot volume metadata (via Storage Foundation 5.0) so that the snapshot can be re-imported back on the original host. Fire Drill imports the BCV and mounts the necessary filesystems. Click 3: Test App. Fire Drill starts up the target Service Group and all its required resources. The test SG is a clone of the production SG and does not impact production. The Service Group starts successfully and we know that we are fully protected at this point in time. Click 4: Reset. Fire Drill shuts down the target SG, unmounts the snapshot and returns the snapshot storage to the array.
