Operating the SAN I/O Module

This chapter describes the operation and interoperability of the SAN I/O Module.

Interoperability

The SAN I/O Module supports interoperability for the following functions:

Port negotiation

The SAN I/O Module has been designed to be highly interoperable. It supports 1 Gbit/sec, 2
Gbit/sec, and 4 Gbit/sec transmit and receive rates with autonegotiation. The actual data signaling
rate used on a port is automatically sensed and set to the rate supported by the device or devices
attached to the port.

If the SAN I/O Module is connected to a device, but is unable to negotiate the signaling rate, the
operator can manually set the speed of each port through the management interfaces.

The SAN I/O Module is compliant with current Fibre Channel standards, including most
current-generation switch N_Ports, NL_Ports, and E_Ports as well as host adapters, Redundant
Array of Independent Disks (RAID) storage devices, hubs, Fibre-SCSI bridge devices, and older
switch families.
