HP StorageWorks P4000 User Manual page 331

storage server Storage server software maintains the customer's data. It reads to and writes
from disks in response to customer reads and writes of SANiQ volumes.
stripe Striped data is stored across all disks in the array, which increases performance
but does not provide fault tolerance.
synchronize The process of copying the most recent snapshot from the primary volume to a
new remote snapshot. On failback, synchronization is the process of copying
the most recent remote snapshot back to the primary volume. The CMC displays
the progress of this synchronization. Also, you can manually synchronize if
necessary to include data that is on the remote volume but not the primary.
target secret Target secret is used in both 1-way and 2-way CHAP when the target (volume)
challenges the iSCSI initiator.
temporary space Temporary space is created when a snapshot is mounted for use by applications
and operating systems that need to write to the snapshot when they access it.
Temporary space can be converted to a volume using the SmartClone process.
thin provisioning Thin provisioning reserves less space on the SAN than is presented to application
servers.
Trap Community The Trap Community String is used for client-side authentication when using
String SNMP.
unicast Communication between a single sender and a single receiver over a network.
VIP virtual IP address
virtual IP address A highly available address that ensures that if a storage system in a cluster
becomes unavailable, servers can still access the volume through the other storage
systems in the cluster.
virtual machine A virtual storage appliance that provides one or more simultaneous storage
environments in which SAN/iQ may execute as though they were running on
the bare iron.
virtual manager A manager that is added to a management group but is not started on a storage
system until it is needed to regain quorum.
volume A logical entity that is made up of storage on one or more storage systems. It
can be used as raw data storage or it can be formatted with a file system and
used by a host or file server.
volume set Two or more volumes used by an application. For example, you may set up
Exchange to use two volumes to support a StorageGroup: one for mailbox data
and one for logs. Those two volumes make a volume set.
volume lists For release 7.0 and earlier, provide the link between designated volumes and
the authentication groups that can access those volumes. Not used in release
8.0 and later.
volume size The size of the virtual device communicated to the operating system and the
applications.
