12 Using the VMware Hot Disk API & Veritas Cluster Server to control VM access to storage Controlled VM access via Veritas Cluster Server Enable vmotion, HA & DRS etc.. Utilize Hot Disk API for attaching disks Wider support of disk types available incl RDM Cluster controls access and has better guard against splitbrain. Easy transfer of operational knowledge to virtual environments. VM1 ESXi 1 VM1 Boot Data Private Links Shared Datastore ESXi 2 Boot 13

13 Veritas Cluster Server makes application failover compatible with vmotion lication Recovery Offline Online Failover an application in the case of an application, operating system or ESX host failure Minimize downtime during Operating System maintenance by failing applications across VMs Reduce recovery times significantly by eliminating VM reboots Fault Detach Data Disks VM1 ESXi 1 Private Links ESXi 2 Attach Data Disks to VM1 Boot Boot Data Shared Datastore 14

14 Operational Scenarios : Handling Split brain scenarios Handling Split brain scenarios Network split: In scenarios of network split, the passive node would detect active node down and initiate a SG failover. Detach operations wont succeed implying the locks are not released, the attach operations too fail. This causes the failover to error out status quo is maintained, avoiding data corruption.
