Software Overview
59 IP Storage Router SR2122-2 User Guide
Figure 30: FCIP
In addition to providing services for accessing storage over IP networks, storage
router software provides the following services:
■ VLAN Access Control provides IP access control to storage based on a
VLAN identifier (VID) number (in addition to access control through access
lists).
■ Authentication provides iSCSI authentication using AAA authentication
methods.
■ High Availability (HA) provides the ability to group storage routers in a
cluster for failover and other cluster-related functions (for SCSI routing only).
■ E_Port with FC Fabric Zoning provides the ability to connect FC ports to
FC switches and participate in fabric zoning, manage zoning, and support
zone mergers
■ SNMP/MIB support provides network management of the storage router
through SNMP using selected MIBs.
■ Gigabit Ethernet Interface features provides the ability to assign a
management IP address per Gigabit Ethernet interface, multiple IP addresses
per SCSI routing instance, and an optional secondary Gigabit Ethernet
interface per IP address used for SCSI routing or SR2122-2 management.
When the SR2122-2 is deployed for FCIP, provides primary and optional
secondary Gigabit Ethernet interfaces to the FCIP peer.
■ FCIP data compression enables the SR2122-2 to dynamically compress
FCIP data traffic for better channel bandwidth utilization.
■ Buffer credit extension enables the SR2122-2 to donate buffer credits from a
donor port to selected FC ports.
