17 HP 3PAR Peer Persistence with Transparent Failover
HP 3PAR Peer Persistence is available for VMware configurations from version 3.1.2 MU2 of the
HP 3PAR OS software. Peer persistence provides the ability to redirect host I/O, either manually
or automatically, from the primary to the secondary storage system in a manner that is transparent
to the host while causing minimal disruption to service.
The HP 3PAR Peer Persistence switchover operation migrates host I/O from one storage array to
the other and reverses the direction of data replication. The switchover is a manual operation
designed to facilitate service optimization and storage system maintenance activities within a
high-availability data storage solution.
The HP 3PAR Peer Persistence failover operation automatically redirects host I/O from a failed
source system to the target storage system, again in a manner that is transparent to the host. Peer
persistence failover uses the HP 3PAR Quorum Witness to monitor for HP 3PAR storage system
failure in order to determine whether a failover of host service is required. The HP 3PAR Quorum
Witness and related infrastructure provide key inputs to the trigger mechanism used by peer
persistence technology to execute the migration of the I/O path.
HP 3PAR Peer Persistence switchover and failover are keys elements in providing and maintaining
a high-availability storage solution between two sites.
HP 3PAR Quorum Witness Requirements
Supported environments and requirements for the HP 3PAR Quorum Witness are shown in Table 6
(page 132).
