SAN Router features
Feature Description
Intelligent Ports Two intelligent ports, which can be configured for
Internet Small Computer Systems Interface (iSCSI) or
Internet Fibre Channel Protocol (iFCP).
Internet Fibre Channel
Protocol (iFCP)
standards track
protocols The SAN Router supports the IETF draft standard for
iFCP, which provides connectivity and networking for
existing Fibre Channel devices over a TCP/IP network.
iSCSI A TCP port can be configured for either iSCSI or iFCP.
R_Ports Support for FC-SW2 standard E_Port (Open Fabric
mode), McDATA Fabric mode, and Brocade Fabric mode
allows you to fully integrate the SAN Router into an
existing fabric that includes one or more fabric switches.
Fast Write The Fast Write software feature available on intelligent
ports improves the performance of write operations
between Fibre Channel initiators and targets in a Wide
Area Network (WAN). The improved speed depends on
the WAN Round Trip Time (RTT), available buffer space
on the target, number of concurrent I/Os supported by
the application and application I/O size.
Requires feature 1603.
Zoning Using SANvergence Manager, network management
software, or the command line interface (CLI), you can
create zones across networks. The SAN Router provides
for only one zone set, so whatever is zoned is a part of
the Active Zone set on the SAN Router.
Real-time and historical
system logs The Element Manager and LogViewer can be used to
look at current system log messages from the connected
SAN Router.
Compression Compression technology available on intelligent ports
identifies repetitive patterns in a data stream and
represents the same information in a more compact and
efficient manner. By compressing the data stream, more
data can be sent across the network even if slower link
speeds are used.
Requires feature 1603.
