DSM Device Specific Module.
DSM for MPIO The HP 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.
full provisioning Full provisioning reserves the same amount of space on the SAN as is presented to application
servers.
ghost storage When using Repair Storage System, a "ghost" storage system acts as a placeholder in the cluster,
system keeping the cluster intact, while you repair or replace the storage system.
Graphical Legend Describes all the icons used in the CMC:
hardware reports Hardware reports display point-in-time statistics about the performance and health of the storage
system, its drives, and configuration.
hostname The hostname on a storage system is the user-definable name that displays below the storage
system icon in the network window. It is also visible when the users browse the network.

Console
ID LED LED lights on the physical storage system so that you can find that system in a rack.
iSCSI Internet small computer system interface. Like an ordinary SCSI interface, iSCSI is standards-based
and efficiently transmits block-level data between a host computer (such as a server that hosts
Exchange or SQL Server) and a target device (such as the HP All-in-One Storage System). By
carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets
and to manage storage over long distances.
iSCSI load Improves iSCSI performance and scalability by distributing iSCSI sessions for different volumes
balancing evenly across storage systems in a cluster.
license key A WWN-encoded sequence that is obtained from the license key fulfillment website.
Link Aggregation A type of network bonding in which the logical interface uses both NICs simultaneously for data
Dynamic Mode transfer.
log files Log files for the storage system are stored both locally on the storage system and are also written
to a remote log server.
logical site This site is on an isolated network and power connection than the other sites. However, it can
be in the same physical location as one of the real sites. Also, a site for a Failover Manager.
management A collection of one or more storage systems which serves as the container within which you cluster
group storage systems and create volumes for storage.
managers Manager software runs on storage systems within a management group. You start managers on
designated storage systems to govern the activity of all of the storage systems in the group.
MIB Management information base. A database of managed objects accessed by network management
protocols. An SNMP MIB is a set of parameters that an SNMP management station can query
or set in the SNMP agent of a network device (for example, a router).
