Persistent Target
iSCSI targets to which the iSCSI initiator reconnects whenever the computer is rebooted so that the
initiator always appear to be connected to the target.
Physical Disk
A disk, which provides storage capacity and exists as a physical entity. It can be of different type
such as SAS, SATA, and SSD.
Pool
A virtual medium in which multiple physical disks configured using the RAID technology, are
regarded as one large disk. The pool is created using the Storage Manager.
Port
A physical connection point on devices such as computers, switches, and disk arrays, which is used
to connect to other devices on a network.
Port Number
Port Number is a part of the internet addressing information used to identify the specific process to
which the network data is to be delivered.

Proxy server
A server that acts as an intermediary between a client and the other servers in order to achieve

proxy server, requesting some service available from a different server. The proxy server evaluates
the request according to its filtering rules.
R
RAID
See Redundant Array of Independent
Redundant Array of Independent Disks
A storage technology that provides increased data performance and reliability through data
redundancy and striping, combining multiple disk drives components into a single logical unit.
Replicate
When Replicate is performed, data copy from Master Volume (MV) to Replica Volume (RV) starts, to
reflect the content of the MV into the RV. Updates made in the MV after Replicate is performed are
also reflected into the RV.
Replication
Replication is a technique that copies the exact same data from a Master to a Replica. Since the
Master and the Replica are completely independent, data reliability is high.
Restore
When Restore is performed, data copy from Replica Volume (RV) to Master Volume (MV) starts to
reflect the data stored in the RV at the start of Restore into the MV. When Restore (update) is
performed, updates made in MV after Restore are reflected in RV.
