– Poll interval
– Number of resources
• System CPU and memory overhead

• Problem: Large storage object config proportionately increases failover time
– Eg.: A config with 150+ disks, 25+ DGs, 150+ volumes can take 30+ minutes to failover
• Contributors to long failover time
– DG deport, DG import, Rescan, Object creation, Volume arrival handling
• Solution:
– Avoid full deport/import of disk group during failover
– Optimize the online/offline mechanisms of resources like MountV, VMDg
SM B17 15
Reduce Failover Time

• DG deport on current active node
• Disk re-scanning on new active node
• Creating volumes on new active node
• Handling volume arrivals
• Flush & un-mount volumes on previous active node
• DG RW and RO access changes
• File system re-mount on new active node

Asynchronous Replication
RPO = near 0 RTO = mins
Primary Site DR Site Any Distance
• 2 clusters – across subnets, dissimilar hardware & config
• One click DR
– reverse replication
– mount disks/volume
– plumb vIP & update DNS
– start app in dependency order
• One click failback
• Out-of-box replication agents
• Flexibility to pick heartbeat & failover policy for local vs remote nodes cluster

Simulate DR Failover
• Test the recovery path
– storage, server, network, application
• No impact on production
– Everything done on DR site
– On replicated volume snapshot
– No IP conflicts
• Easy to use
– Automated
– Wizard based setup and ongoing tests
– More frequent DR tests leads to faster DR tests
