Overview

The SilkWorm 2100 switch is an 8-port, gigabit Fibre Channel switch in the SilkWorm

2000 switch family. As a low-cost, high-performance alternative to a hub-based solution,

the SilkWorm 2100 is ideal for storage or server area network (SAN) environments with

hosts and devices supporting arbitrated loops (FC-AL).

The SilkWorm 2100 Arbitrated Loop

With FC-AL, multiple devices can share the gigabit bandwidth. However, unlike a hub-

based solution that physically connects ports to form a shared loop, the SilkWorm 2100

logically connects ports, separately managing and controlling each part of the loop or

looplet. This logical connection offers superior performance and reliability over hub-

based approaches.

Each of the eight ports of the SilkWorm 2100 switch forms a looplet; the looplets are

logically connected to form an FC-AL. When a loop is formed, a Loop Initialization

Protocol (LIP) initializes all the devices on each looplet. When the LIP sequence

completes, a virtual arbitrated loop is formed from the looplets that successfully complete

initialization; looplets that failed are not included in the full loop and, therefore, because

the looplets are connected logically, a failing device does not disable the entire loop.

In a traditional arbitrated loop environment, once the FC-AL is formed, a device arbitrates

for the loop to connect to a target device. When arbitration is granted, the device sends

data frames along the loop to the target device; only when the data frame transfer is

complete are other devices on the loop allowed to arbitrate for the loop.

In the SilkWorm 2100 environment, data frames are buffered within the switch if the

destination device is busy and data frames from multiple sources can be buffered and

delivered during a single arbitration. This increases efficiency and improves the overall

throughput of the SAN.

Overview

The SilkWorm 2100 Advantage

The SilkWorm 2100 switch offers advantages in the following areas:

• Performance

• Reliability

• Manageability

• Flexibility

Performance

The SilkWorm 2100 switch offers enhanced performance:

Data Transfer A device arbitrates only among the devices in its looplet; frames are

transferred to the switch for forwarding to a destination device on

another looplet.

The non-blocking architecture of the SilkWorm 2100 switch

guarantees full-speed data delivery in all traffic conditions.

Cut-through routing ensures a maximum latency of 2 microseconds

from switch port to switch port, allowing parallel data transfers of

up to eight (one per loop) simultaneous transactions at a time.

Whereas traditional hub-based arbitrated loops are limited to a total

shared bandwidth of 100 MB/sec, the SilkWorm 2100 switch is

capable of transferring data at eight times (800 MB/sec) that rate.

Buffering Unlike a traditional loop environment where a device is blocked

from transferring data when another device on the loop has control,

the SilkWorm 2100 switch can buffer data within the switch

allowing a device to transfer multiple frames. This allows for

overlapping transfers and improves the overall throughput of

the SAN.

Reliability

The SilkWorm 2100 switch provides enhanced reliability:

Port Isolation The SilkWorm 2100 switch monitors each looplet to ensure proper

device operation. If errors are detected the looplet is not allowed to

initialize and the port is taken out of service. An alert is generated

and the port is monitored until the error condition is cleared. This

enables the loop to operate while the device is isolated and repaired,

thereby preventing a failing device from disabling the entire loop.

Status Reporting The SilkWorm 2100 switch provides extensive statistics, including

a full set of performance and error counters, to aid in diagnosis and

isolation of malfunctioning ports. These statistics are retrieved via

several interfaces such as SNMP, telnet, and an optional Web-based

management interface feature, WEB TOOLS.

Diagnostics Power On Self Tests (POSTs) and online diagnostics monitor

individual ports while the switch is running. Offline diagnostics

isolate problems enabling faster restoration of service.

Hardware Features Redundant fans and a hot-pluggable redundant power supply

option eliminate service down time related to failing power

supplies or fans.
