DSM
Device Specific Module
DSM for MPIO
The HP StorageWorks P4000 DSM for MPIO vendor-specific DSM that interfaces
with the Microsoft MPIO framework.
failback
After failover, the process by which you restore the primary volume and turn the
acting primary back into a remote volume.
failover
The process by which the user transfers operation of the application server over
to the remote volume. This can be a manual operation, a scripted operation, or
VMware enabled.
Failover Manager
A specialized manager running as a VMware appliance that allows you to place
a quorum tie-breaker system into a 3rd location in the network to provide for
automated failover/failback of the Multi-Site SAN clusters. The Failover Manager
is designed to run on VMware ESX Server, VMware Server, and VMware Player.
It is installed on hardware separate from the SAN hardware.
failover recovery
After failover, the process by which the user chooses to fail back to the primary
volume or to make the acting primary into a permanent primary volume.
frame size
The frame size specifies the size of data packets that are transferred over the
network.
