Eclipse™ 2640 SAN Router Administration and Configuration Manual
Introduction
Introduction
The Eclipse 2640 SAN Router (referred to as SAN Router in this
manual) supports iSCSI, iFCP, and R_Port for trunking to both
Internet Protocol (IP) backbones and legacy Fibre Channel (FC)
fabrics. The SAN Routers connect to a wide range of end systems,
including Fibre Channel, NAS, and iSCSI initiators and targets. SAN
Routers support Ethernet and Fibre Channel switching over extended
distances at wire speed.
The SAN Router can be deployed for multiple, concurrent
applications, including SAN routing in the data center (mSAN
routing), SAN routing over distance (iSAN routing) for disaster
recovery, and iSCSI access to Fibre Channel storage.
mSAN routing enables you to build very large, stable fabrics where
faults in one part of the network do not impact traffic in other parts.
For disaster recovery, the backup site can be quite distant, thanks to
McDATA’s patent-pending FastWrite technology, which can sustain
wire-speed throughput in spite of high-link latency. The TCP ports
on the SAN Router can support iSCSI access to Fibre Channel storage.
SAN Routers offer:
• mSAN internetworking for scalable and fault-tolerant SANs.
• Compression for increased bandwidth.
• Support for full fabric, private and public loop Fibre Channel
devices.
• Patent-pending FastWrite
TM
technology for maximizing
throughput across long distances.
• Storage-optimized TCP to ensure high throughput in a dedicated
network in enterprise environments typically used for storage
traffic.
The Eclipse 2640 SAN Router, shown in Figure 1-1 on page 1-3,
contains 16 ports.
• Twelve user-configurable small form factor port (SFP) connectors
(ports 1-12) support Fibre Channel connections.
• Four multiService intelligent SFP port connectors (ports 13-16)
support Internet Fibre Channel Protocol (iFCP) or Internet small
computer systems interface (iSCSI) connections over TCP/IP.
