HPE XP7 High Availability

HPE XP7 High Availability (HA) Software is an Active-Active High Availability Solution offering on HPE XP7 Storage. The high availability feature is implemented based on the XP7 Multi Array Virtualization capability. HPE XP7 High Availability Software supports two use cases: Active-Active HA and ActiveActive Access. Active-Active HA provides 100% storage uptime from a DR configuration even when an array and/or entire datacenter goes offline. Active-Active Access provides non-disruptive, transparent VM and/or clustered application mobility between hosts or servers at the same or different sites. The HA Virtual Storage Machine feature is new to the XP product line. Multi Array Virtualization (MAV) provides the virtualization architecture software to setup local or clustered mirrored volumes that look the same to any supported Host multi-path/cluster software. MAV replicates the data across XP7 arrays up to a synchronous distance and provides delta re-sync capability in case of failure/maintenance. HA can be combined with any of the other traditional mirroring program product like BC, Fast Snap to make additional copies. HA requires a quorum device located on an external storage device. Host then can use generic multi-path solutions for Active-Active access, load balancing as the Virtual Storage Machine hides and handles HA complexity.
