Table 3 SAN Router features
Feature Description
R_Port Support for FC-SW2 standard E_Port as well as
Brocade interoperability mode allows you to fully
integrate the SAN Router into an existing Fibre Channel
SAN that includes one or more Fibre Channel 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.
Router Zoning Using SANvergence Manager, network management
software, or the command line interface (CLI), you can
create zones across networks.
You can use zone sets for periodic reallocation of
network resources. For example, you can have one set
of zones for daytime data transactions and another set of
zones for nighttime backups. You can create zones
across networks.
Real-time and historical The Element Manager and LogViewer can be used to
system logs 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.
Jumbo Frames Since the maximum Fibre Channel payload size is 2112
bytes, two regular Ethernet frames are required. The
Jumbo Frame option extends the Ethernet payload to
2112 bytes. With the support of Jumbo Frames, a Fibre
Channel frame can be mapped to just one Ethernet
frame, providing more efficient transport. For iSCSI
traffic, up to 4K size frames are supported.
