Summary of key findings

The following is summary of key findings discovered during testing.

 Appropriate sizing, including hardware and replication links, is critical for success

 Plan for using two SQL instances for the SharePoint environment, each assigned to their own DR

group, to improve application and replication performance

 Validate cabling and switch zoning configuration

 Set Fibre Channel switch configuration settings for replication, to guarantee in-order packet delivery

 Use proper configuration and load order when implementing HP storage replication products, to

ensure a smooth and successful implementation

o Enable HP Continuous Access EVA licenses

o Create array disk groups on the remote EVA

o Create DR groups

o Add Vdisks to DR groups

o Present replica disks to remote hosts

o Install HP Cluster Extension EVA

o Create a HP Cluster Extension EVA cluster resource for each SQL cluster instance

o Add remote nodes to the cluster

o Install SQL on remote cluster nodes, using the using the add node to existing SQL Server

installation option

o Add HP Cluster Extension EVA cluster resource as a dependency for each disk resource in the

SQL Server instance’s cluster group, completing the HP CLX configuration.

 Create and populate DR group during low activity times to avoid a performance impact during

replication of the initial full copy of LUNs

 Configure the following parameters that determine failover/failback behavior, according to the

appropriate business requirements:

o Use non-current data OK

o Suspend on links down

o RESYNCWAIT/FASTFAIBACK

Conclusion

As part of the HP SharePoint portfolio, HP offers StorageWorks Continuous Access EVA data

replication technology and HP StorageWorks Cluster Extension EVA that provide real-time protection

against application downtime from fault, failure, or site disaster. These two products are easily

implemented. Together, they provide a complete disaster tolerance and disaster recovery solution to

reinstate critical applications at a remote site within minutes after an adverse event.
