Features

The Fibre Channel SAN Switch 16 has the following features:

■ Simplicity— The Fibre Channel SAN Switch 16 is easy to set up and

configure. After the Power On Self-Test (POST), add the switch’s Internet protocol (IP) address. The remainder of the setup is automated.

■ Intelligence— The operating system allows discovery of all connected

devices and determines optimum data paths without intervention.

■ Flexibility— The GBIC modules support single-mode and multi-mode

fiber transmission media. The switch’s modular construction allows flexibility in creating, upgrading, maintaining, and configuring a fabric.

■ Reliability— Highly integrated, reliable, multifunction Application

Specific Integrated Circuits (ASIC) devices are used throughout the switch.

■ High performance— The low-latency, high-performance design

requires no processor data path interaction. The Fibre Channel bandwidth is 100 megabytes per second (MB/s) per port (full duplex).

NOTE: The latency can differ when the device or destination is configured in a loop.

■ Automated congestion management— Virtual channels enable the

switch to perform sophisticated congestion management techniques automatically.

■ Cascading— Switches can be cascaded for large fabric support.

Switches can be interconnected for a large fabric with multiple fabric connections. .

■ Compatibility— The Fibre Channel SAN Switch 16 is designed to

operate with other Compaq StorageWorks Fibre Channel Switches using a compatibility mode.

■ Universal Ports— Switch ports are designed to support F_, FL_, and

E_Port modes of operation. The software automatically selects the optimum mode of operation.

1-4 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Table 1-2 describes the switch’s technical features.

Table 1-2

Fibre Channel SAN Switch 16 Technical Features

Feature Description

Data field size The Fibre Channel frame can be up to 2112 bytes in size. The number

of bytes must be a multiple of 4.

Buffering A total of 128 standard-size receive frame buffers are available for

each set of 4 Fibre Channel ports.

Adjustable buffer-to-buffer credit

Buffer-to-buffer credit for each F/FL_Port can be up to 31 credits. For the E_Port, buffer-to-buffer credit can be a total of 31 credits distributed among all 8 virtual channels.

In order frame delivery

The switch delivers the frames to a destination F/FL_Port in the same order received by the source F/FL_Port. The in-order frame delivery is maintained within a fabric of multiple interconnected switches.

Automatic address assignment

Switch port address identifiers are selected using an automatic address assignment protocol. All ports within a fabric are assigned address identifiers. Each individual switch maintains its own address pool for ports within the switch.

Hardware frame routing

The switch implements hardware routing of frames between communicating ports and supports self-routing of frames between the communicating ports. The path selection in a multiswitch configuration is based on a self-routing protocol.

User-defined routing

The switch allows the configuration of user defined routes. Failed paths are still used in the event of a failure.

Translative mode Translates 8-bit private loop addresses to 24-bit Phantom Public

Addresses to allow fabric-aware devices to access to private devices.

continued

Feature Description

Management The switch can be managed through the SNMP agent, Web

Management Tools, or Telnet included in the Compaq StorageWorks

Command Console software. These items are accessible from the

Internet Protocol over the RJ-45 10/100BaseT Ethernet port or any Fibre Channel port. You can use any SNMP-based management product to access the SNMP agent and any supported Web browser to use the Java Web Management Tools.

Name Server

The Name Server feature is based on the Simple Name Server model defined in the Fibre Channel Standard. This function allows external devices to discover other fabric-connected devices. Name Server manages a database that relates external device quantities, including mappings between N/NL_Port 24-bit Fibre Channel physical addresses, World Wide Names (WWN), IP addresses, FC-4 device types, and Initial Process Associators. External devices can register and query this information using the Name Server function, which is distributed across switches in a fabric.

Performance

A minimum aggregate routing capacity of 4,000,000 frames per second is

specified for Class 2, Class 3, and Class F frames. Non-blocking throughput of

up to 16 x 100 MB/s (1.6 gigabytes per second [GB/s]) is provided.

A maximum switch latency of less than two microseconds is specified for

Class 2, Class 3, and Class F frames when the output port is free.

Manageability

The Fibre Channel SAN Switch 16 can be managed in-band by using Fibre

Channel protocol, or out-of-band by connecting to the 10/100BaseT Ethernet

port. Management interfaces include SNMP, Web Management Tools, or

Telnet.

1-6 Compaq StorageWorks Fibre Channel SAN Switch 16 Installation and Hardware Guide

Compatibility

The Fibre Channel SAN Switch software (version 2.0 and above) is compatible with the Fibre Channel Switch software (Version 1.6c or 1.6d), allowing both types of switches to operate in the same fabric. To accomplish this compatibility, the Fibre Channel SAN Switch 16 must be configured to use a specific addressing mode. This mode is designated “VC Encoded Address Mode.”

Invoke this mode using the

configure command, as described in Appendix A of

the Compaq StorageWorks

Fibre Channel SAN Switch Management Guide.

When using this compatibility mode, the maximum switch count in a fabric is reduced from 239 to 32, and the maximum number of multicast groups is reduced from 256 to 31.

If the compatibility mode is not set, the following error message displays when you interconnect a Fibre Channel SAN Switch 16 and a Fibre Channel Switch:

FABRIC, SEGMENTED, LOG_WARNING Description: Fabric segmented. Probable Cause: Incompatible fabric parameters/switches or conflict zones. Action: Reconfigure fabric or zones. See configure command.

Reliability

The following features ensure the switch’s reliability:

■ POST

■ BootROM Memory Testing

■ Temperature and fan-speed monitoring

■ Low component count

■ Optional dual-redundant hot-pluggable power supplies

Overview 1-7

Serviceability

The following features enhance the switch’s serviceability:

■ Simple enclosure

■ Loopback test modes for service

■ User-friendly diagnostics

■ No jumpers or switch settings

■ Error and significant event logging and reporting

■ Modular Field Replaceable Units

NOTE: For more information about field replaceable units (FRUs), see Chapter 7, “Repair and Replacement.”

NOTE: The Fibre Channel SAN Switch 16 can support a dual-redundant power supply configuration with hot-pluggable power supplies.

GBIC Modules

The Fibre Channel SAN Switch 16 accommodates up to sixteen GBIC modules. All interfaces have status lights on the front panel for quick, visual checks of the GBIC modules’ status and activity. If your installation requires less than 16 GBIC modules, a metal, spring-loaded door protects the unused port positions.

Shortwave (GBIC-SW) and longwave (GBIC-LW) GBIC modules are supported. Figure 1-3 shows a GBIC module.

Figure 1-3. GBIC module

Overview 1-9

GBIC-SW Module

The GBIC-SW module with the subscriber connector (SC) color-coded black

is based on short wavelength 850 mm lasers supporting 1.0625 GB/s link

speeds. The GBIC-SW module supports 50-micron multi-mode fiber optic

cables in lengths up to 500 meters. The GBIC-SW module uses a Class 1 laser,

which complies with the 21 CFR, subpart (J) standard as of the date of

manufacture. The GBIC-SW module is shipped with a protective plug that

should remain in place when no fiber optic cable is connected to the port.

GBIC modules for the Fibre Channel SAN Switch 16 must be ordered

separately. The Compaq part number for the shortwave optical GBIC module

for multi-mode cable is 380561-B21.

GBIC-LW Module

The GBIC-LW module with the SC color-coded blue is based on long

wavelength 1300 mm lasers supporting 1.0625 GB/s link speeds. The

GBIC-LW module supports 9-micron single-mode fiber optic cables in lengths

up to 10 kilometers. The GBIC-LW module is shipped with a protective plug

that should remain in place when no fiber optic cable is connected to the port.

Two single-mode GBIC modules and a short single-mode test cable can be

ordered in a kit (part number 340412-B21).

In the Switch Management Application page of the Web Management Tools,

the GBICs are identified differently depending on the type of GBIC and the

supplier. Some examples of the displays include “ID” for VIXEL shortwave

GBICs and “SW” for IBM shortwave GBICs.

Switching Function

The Fibre Channel SAN Switch 16 switching function is based on a central

memory bank and its associated data path control. Each switch port stores

received frames in the central memory, while passing a buffer pointer to the

forwarding port’s transmitter. The switch uses cut-through routing to route

frames from the receiving port to the transmitting port, providing the

transmitting port is free, without waiting for the end of the frame to be

received. This provides a low-latency data path within the switch. If the

transmitting port is busy, the frame can be temporarily stored in the switch’s

memory bank.

Selecting an Operating Location

The switch should be located in a secure or limited-access area to ensure that cable connections are not compromised. The operating location you select for the switch must meet the cooling air requirements and power requirements described in the following sections.

Cooling Requirements

Cooling air is drawn into the switch chassis by four fans mounted near the rear of the chassis. Exhausted air is expelled through vents in the front of the chassis. The combined air flow through the switch is 75 cubic feet per minute (cfm), with nominal bulk flow of 15 cfm.

CAUTION: Do not block the front or rear air vents. The switch uses ambient air for cooling.

Power Requirements

The AC power cord is connected to the switch connector on the right side of

the switch front panel. If you have dual-redundant power supplies, the second

AC cord is connected to the switch connector on the left side of the switch

front panel. Each AC power sources must meet these requirements:

■ A properly wired, earth-grounded AC outlet

■ Voltage capability of 85-265 VAC

■ Input voltage frequency of 47-63 Hz

■ Power capability of 150 watts, maximum

The switch has an auto-ranging power supply that automatically accepts

voltages within its range. There is no provision for surge protection built into

the switch power supply, so the AC source should include provisions to ensure

clean AC power.

Selecting a Switch Mounting Method

The switch can be placed on a flat surface, such as a tabletop, or mounted in an

optional, standard 19-inch equipment rack with an optional rack mounting kit,

part number 167365-B21.

Surface Mounting

To operate the switch on a surface, place the four rubber feet, provided in the

kit, on the bottom surface of the switch. Continue the installation procedure

with “Installing GBIC Modules,” later in this chapter.

Rack Mounting

You can install the switch in a RETMA 42U rack, in a Compaq rack, or in a

metric SW600 rack. Refer to the documentation that came in your

rack-mounting option kit for more information.

Installing GBIC Modules

The switch can accommodate up to 16 GBIC modules. GBIC modules are

hot-pluggable. To install a GBIC module:

CAUTION: The GBIC modules contain static-sensitive components. Use electrostatic discharge (ESD) precautions while handling GBIC modules.

1. Insert a GBIC module into a Fibre Channel port. The module is keyed

and can only be inserted one way.

CAUTION: Do not force the GBIC module into a port if you feel resistance.

2. Fully insert the GBIC module until it is properly seated in the

Fibre Channel port. If you are using a GBIC module with a locking bar, lock the module in place with the locking bar. For other GBIC modules, the latch prongs automatically lock to prevent accidental removal of the GBIC module.

3. Insert a protective plug over the GBIC module’s fiber-optic connectors.

4. Repeat the procedure for each GBIC module to be installed.

Cable Specification

All cables connect at the front of the switch.

Fibre Channel Cables

Optical cables for the switch must be ordered separately. 500 meters or less cables should be multi-mode Fibre Channel cables. Cables that are longer than 500 meters should be single-mode. Multi-mode optical cables are connected to shortwave GBIC modules in the switch. Single-mode optical cables are connected to longwave GBIC modules in the switch. Multi-mode cables should use 50/125 optical fibers, SC Duplex connectors with a PC finish. Use of 62.5/125 should be restricted to situations where 62.5/125 optical fiber was previously installed and the link lengths are to be kept shorter than 200 meters. Single-mode cables typically use 9/125 optical fibers for distances up to 10 km.

Table 2-1 lists the cable specifications for Fibre Channel cables.
