In addition to providing services for accessing storage over IP networks, the SN 5428-2 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, Enable and Login authentication using AAA authentication
•
methods
High Availability (HA)—provides the ability to group storage routers in a cluster for intelligent
•
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 SN 5428-2 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 SN 5428-2
management. When the SN 5428-2 is deployed for FCIP, provides primary and optional secondary
Gigabit Ethernet interfaces to the FCIP peer.
FCIP data compression—enables the SN 5428-2 to dynamically compress FCIP data traffic for
•
better channel bandwidth utilization
FCIP SACK support—uses selective acknowledgement (SACK) to overcome the limitations of
•
recovering from multiple lost packets during a TCP transmission for FCIP instances configured as
TCP clients or servers
•
Buffer credit extension—enables the SN 5428-2 to donate buffer credits from a donor port to
selected FC ports
•
Secure Sockets Layer (SSL) support—provides HTTPS connection for secure access through the
web-based GUI
•
Secure Shell (SSH) protocol version 2 support—provides high encryption and authentication for
interactive management sessions, and is a common replacement for Telnet
Routing Information Protocol (RIP) listening support—allows the SN 5428-2 to learn dynamic
•
routing using RIP (version 1 or version 2) listening
Service Location Protocol (SLP) support—provides the ability to advertise targets of specified SCSI
•
routing instances to initiators or servers that use SLP
Internet Storage Name Service (iSNS) support—provides the ability to register iSCSI targets with
•
an iSNS server, allowing iSCSI initiators to dynamically discover available storage targets
