Introduction to McDATA Multi-Protocol Products 1 - Data compression - SAN router software identifies repetitive information in an output data stream and applies a compression algorithm to ensure the data is more compact and efficiently transmitted. - FastWrite technology - FastWrite software improves write performance over WANs by responding to initiator write commands with local transfer ready (XFR_RDY) commands, and buffering output data at the SAN router closest to the corresponding target device. This eliminates XFR_RDY command transmissions and minimizes bursty data transfer over the WAN, thus reducing round-trip delays that are characteristic of extended-distance links. - Jumbo frames - Two Ethernet frames are typically required to transmit one Fibre Channel frame consisting of 2,112 bytes. The jumbo frame feature maps one Ethernet frame to one Fibre Channel frame, thus providing more efficient data transmission. • High-availability - To ensure an availability of 99.9%, multiprotocol SAN router design provides a redundant configuration of power supplies and cooling fans. High availability is also provided through concurrent firmware upgrades and spare or unused multi-protocol ports. • Multi-protocol support - SAN routers support the following protocols: - FCP, including first, second, and third editions of the Fibre Channel Physical and Signaling Interface (FC-PH, PC-PH-2, and FC-PH-3), arbitrated loop (FC-AL), and R_Port. Refer to R_Port Operation for a discussion about R_Port operation. - IP networking protocols, including mFCP, iFCP, iSCSI, and Internet storage name service (iSNS). The iSNS protocol provides intelligent storage device discovery and management services comparable to those found in Fibre Channel SANs. Network protocols operate at up to fullduplex GbE bandwidth at 1,000 megabits per second (Mbps). Eclipse 1620 SAN Router The Eclipse 1620 SAN Router is a first-generation product that provides extended-distance, multi-protocol fabric connectivity. The primary function of the Eclipse 1620 SAN Router is to implement iFCP-based BC/DR solutions. Figure 1-10 illustrates the SAN router. 1-24 McDATA Products in a SAN Environment - Planning Manual

FastWrite software improves write

performance over WANs by responding to initiator write

commands with local transfer ready (

XFR_RDY

) commands,

and buffering output data at the SAN router closest to the

corresponding target device. This eliminates

XFR_RDY

over the WAN, thus reducing round-trip delays that are

characteristic of extended-distance links.

Two Ethernet frames are typically required to

transmit one Fibre Channel frame consisting of 2,112 bytes.

The jumbo frame feature maps one Ethernet frame to one

Fibre Channel frame, thus providing more efficient data

transmission.

To ensure an availability of 99.9%, multi-

of power supplies and cooling fans. High availability is also

provided through concurrent firmware upgrades and spare or

unused multi-protocol ports.

FCP, including first, second, and third editions of the

Fibre

Channel Physical and Signaling Interface

(FC-PH, PC-PH-2, and
