Data Field Size
The Fibre Channel frame's data field size is up to 2112 bytes.
Frame Delivery
The Switch delivers the frames via the destination F_Port in the same order received by the source F_Port. The in-order frame delivery is maintained within a Fabric of multiple interconnected Switches.
Management
The Switch may be managed via Telnet, the SNMP agent, the SCSI-3 SES protocol agent, and the Web Tools via StorageWorks Command Console software. The last three entities are accessible via the Internet Protocol over RJ45 10BaseT Ethernet port or any Fibre Channel port. You can use any SNMP-based management product to access the SNMP agent. You may use any supported Web browser to use the Web Tools.
Performance
A minimum aggregate routing capacity of 8M frames/sec is specified for Class 2, Class 3, and Class F frames. Non-blocking throughput of up to 16 x 100MBytes/sec (1.6 GBytes/sec) is provided.
The Switch is used to connect network servers with storage devices, such as Compaq's RA8000/ESA12000 HSG80 RAID Array Storage Subsystems, to create a Storage Area Network (SAN).

Fibre Channel Switch Features

  • Simplicity - After Power-On Self-Test (POST), you need only to enter the Internet Protocol (IP) address. The remainder of the Switch setup is automated.

  • Intelligence - Supports up to 32 interconnected Switches; firmware allows discovery of all connected devices and determines optimum data paths without user intervention.

  • Flexibility - The Switch's modular design includes multiple interface cards. Supports G_Port (F_Port and E_Port) FL_Port cards, FL_Port cards.

  • Reliability - Highly integrated, reliable, multifunction (ASIC) devices are incorporated into the Switch's design.

  • High performance - Low-latency, high-performance design requires no CPU data path interaction resulting in a worst-case data transfer latency of less than two microseconds. The latency may differ when the destination is a loop.

  • Automated congestion management - Virtual channels lets the Switch use sophisticated congestion management techniques that are performed automatically by the Switch.

  • Cascading - Incorporating a cascade design, up to 32 Switches can be interconnected for a large Fabric with hundreds of Fabric connections.

FEATURE DESCRIPTION
Login (FC)
Explicit Fabric login is supported (public and private)
Probing
Automatic discovery of devices and auto registration with the Fabric Simple Name Service (SNS). For private devices, translation mode is set so that other Fabric attached devices can communicate with them.
Virtual Channels
The Switch has 8 virtual channels and 4 priority levels supporting each Switch port. Different virtual channels are automatically assigned with different priority levels to accommodate various types of data flow, different communications protocols and user applications. Virtual channels provide a flexible congestion management that is also used to separate traffic among: 
  • Fibre Channel Link Control frames and Data frames
  • Class 2, Class 3, and Class F frames
  • E_Port, F_Port, and FL_Port destined traffic
Data Field Size
The Fibre Channel frame's data field size is up to 2112 bytes.
Zoning
Zoning is a Fabric management service used to create logical device subsets within a Storage Area Network (SAN) which enables resource partitioning for management and access control.
Buffer-to-buffer credit
Buffer-to-buffer credit for each F_Port can be up to 16 credits. For the E_Port, buffer-to-buffer credit can be a total of 62 distributed among all 8 virtual channels. 

The FL_Port uses the alternate buffer-to-buffer credit management model. Each FL_Port may be configured for Open and supports a BB_Credit of 0 or 1. Up to 16 credits can be made available when opened. Open transmit credit can be 0 or 1 on a per-destination NL_Port basis.

Time Out Values
Both R_A_TOV (Resource Allocation Time Out Value) and E_D_TOV (Error Detect Time Out Value) are adjustable in 1-millisecond increments via Telnet.
Fabric Name
An automatic Fabric Name assignment method is used in a multi-Switch configuration.
Frame Delivery
The Switch delivers the frames via the destination F_Port in the same order received by the source F_Port. The in-order frame delivery is maintained within a Fabric of multiple interconnected Switches.
Address Assignment
The Switch follows the addressing hierarchy defined in the Fibre Channel Standard. The Switch port address identifiers are selected using an automatic address assignment protocol. All ports within the switching Fabric (F_Ports, FL_Ports and E_Ports) are assigned address identifiers. Each Switch maintains its own address pool. The management of address identifiers and assignment of the address pool to the individual Switches are performed by the designated address managers within the Fabric.
Broadcast and Multicast
The system supports up to 32 multicast groups, one is reserved for broadcast. Any port can be a member of multiple groups. In addition to the unicast routing table, each port has its own multicast routing table. The Alias Server is responsible for setting up and removing multicast groups.
Frame Routing
Self-routing of frames between the communicating ports is supported. The path selection in a multiSwitch configuration is based on a self-routing protocol.
Management
The Switch may be managed via Telnet, the SNMP agent, the SCSI-3 SES protocol agent, and the Web Tools via StorageWorks Command Console software. The last three entities are accessible via the Internet Protocol over RJ45 10BaseT Ethernet port or any Fibre Channel port. You can use any SNMP-based management product to access the SNMP agent. You may use any supported Web browser to use the Web Tools.
Name Server
The Name Server function is based on the Simple Name Server model defined in the Fibre Channel Standard. This function is provided by the embedded N_Port with the alias address, FFFFFCh, to register address mapping between the Nx_Port 24-bit Fibre Channel physical address (Nx_Port identifier) and the logical addresses such as Worldwide Names, IP addresses, FC-4 device types, and Initial Process Associators. The Name Server also provides the de-registration and query functions from other nodes or Nx_Ports for logical address translations to the corresponding Nx_Port identifiers.
Alias Server
The Alias Server is based on the Fibre Channel Standard. The function is provided by the embedded N_Port with the alias address, FFFFFAh. It manages multicast groups.

Performance

A minimum aggregate routing capacity of 8M frames/sec is specified for Class 2, Class 3, and Class F frames. Non-blocking throughput of up to 16 x 100MBytes/sec (1.6 GBytes/sec) 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 Switch is managed locally with the four front panel buttons and the front panel display. Remote management is also available through Telnet, SNMP, or with the Web.

Modularity

The modularity built into the Switch allows:
  • Plug-in interface cards for flexibility and upgrade easeMixing both G (For E) ports and FL ports
  • Adding two to eight cards to each Switch with each card accommodating two 1-Gbps ports (2 Gbps total per card) each port is full-duplex (bi-directional at this rated throughput)
  • Support for different transmission media for each port.
These modularity components create a very flexible Switch, capable of meeting a wide range of interconnection and communication requirements.

Reliability

The Switch has the following features to ensure its reliability:
  • Power-On Self-Test (POST)
  • Bootrom Memory Testing
  • Temperature and fan-speed monitoring
  • Low component count

Serviceability

The Switch has the following features, which enhance its serviceability:
  • Simple enclosure
  • Loopback test modes for service
  • User-friendly diagnostics
  • No jumpers or Switch settings
  • All Field Replaceable Units (FRU) are modular, and are:
    • CPU board
    • GBIC modules
    • Interface cards
    • Power supply
    • Chassis, front panel assembly, and motherboard.
