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.
