Introduction
Compaq StorageWorks SAN Switch 16
The Compaq StorageWorks SAN Switch 16 is a 16-port Fibre Channel switch
that provides a flexible switching platform to meet both low-latency and
high-throughput demands. It consists of a motherboard with connections for
up to 16 Giga Bit Interface Converter (GBIC) modules, one or two power
supplies, a fan assembly, a chassis with an RJ-45 Ethernet connection, and a
front panel display with a keypad. The switch’s management functions let you
control and monitor fabric topology, frame throughput, error statistics, fans,
cooling, media type, port status, and a variety of other information to aid in
system debugging and performance analysis.

Compaq StorageWorks SAN Switch 16
Features
The SAN Switch 16 has the following features:
■Simplicity—The SAN Switch 16 is easy to set up and configure. After
the Power-On Self-Test (POST), just 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 (ASICs) 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 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 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.

Table 1-2 describes the switch’s technical features.
Table 1-2
Compaq StorageWorks SAN Switch 16 Technical Features
Feature Description
Login (FC) Explicit fabric login is supported.
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.

Compaq StorageWorks SAN Switch 16 Technical Features
continued
Feature Description
Management The switch can be managed through Telnet, the SNMP agent, or Web
Management Tools included in the 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, 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 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 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 Telnet, SNMP, or Web Management Tools.
