HP StoreVirtual 4000 Storage - Manual (Page 50)

DSM Device Specific Module.
DSM for MPIO The HP StoreVirtual DSM for Microsoft 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
system When using Repair Storage System, a “ghost” storage system acts as a placeholder in the cluster,
keeping the cluster intact, while you repair or replace the storage system.
Graphical Legend Describes all the icons used in the CMC:
•
Items tab - displays the icons used to represent virtual items displayed in the CMC
•
Hardware tab - displays the icons that represent the physical storage units.
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.

Centralized
Management
Console management interface for the LeftHand OS software.
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
balancing Improves iSCSI performance and scalability by distributing iSCSI sessions for different volumes
evenly across storage systems in a cluster.
LeftHand OS
interface When you initially set up a storage system using the Configuration Interface, the first interface
that you configure becomes the interface used for the LeftHand OS software communication.
license key A WWN-encoded sequence that is obtained from the license key fulfillment website.
Link Aggregation
Dynamic Mode A type of network bonding in which the logical interface uses both NICs simultaneously for data
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
group A collection of one or more storage systems which serves as the container within which you cluster
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.
