Overland Storage REO 9000 with ProtectionPAC Software
iSCSI uses standard Ethernet switches and routers to move the data
from server to storage. It also allows IP and Ethernet infrastructure to
be used for expanding access to storage area network (SAN) storage
and extending SAN connectivity across any distance.
Tip:
Initiator. The client is an initiator that plays the active role in issuing
commands. In iSCSI terms, an initiator is a logical system component
(usually present in the form of a device driver) that sends SCSI I/O
commands to a target over an I/O bus or network. In this application,
the initiator accompanies the initiator software or IP storage HBA on
your application or backup server.
iSCSI target. The server is a target that plays the passive role in
fulfilling client requests. An iSCSI target is a logical system
component within an iSCSI appliance that receives SCSI I/O
commands from an initiator and executes them. A target includes one
or more logical units (LUs); each LU is a SCSI device, such as a disk
or tape drive. In this application, the target is the array of disks on the
REO Appliance.
