3.2.1 Connecting a Fibre Channel Array

The Diamond Storage Array supports up to two Fibre Channel Host Interface Cards (HIC). Physical connections and CLI commands contribute to the Fibre Channel topology.

The cable you use depends upon your application, the environment and the distance required for your storage area network.

To comply with FCC and CE EMI for the 2-gigabit

Host Interface Card, use fiber optic cables.

The Diamond Storage Array may have two Fibre Channel Host Interface Cards (HIC). In 2 gigabit Fibre Channel arrays, each HIC is connected by a Fibre Channel cable via a SFP (small form factor pluggable) module into a point-to-point or loop Fibre Channel topology.

Install the SFP according to the manufacturer’s instructions.

Each HIC has two ports and an on-board hub. Each port has an SFP module to connect to Fibre Channel. Each HIC is independent of the other, so that one may be connected into a point-to-point topology and the other into a loop. However, if one port in a HIC is connected into a point-to- point topology, the other port cannot be used.

One of the advantages of using loop topology for Fibre Channel connections is that it allows arrays to be daisy-chained together.

Autoconfiguration

The array automatically determines which HICs are installed and if they are in loop or point-to- point topologies.

If you wish to see how the unit has been set up, go to the CLI commands and type Info or go to the Status page of the ExpressNAV interface. The return displays the data rate and connection mode for each HIC (FC 0 and FC 1).

Manual configuration

You may manually configure the array using CLI commands (refer to Command Line Interface Use and Guidance on page 29.) or access the Fibre Channel page of the ExpressNAV interface (refer to ATTO ExpressNAV: Browser-based Interface on page 25).

•FCConnMode specifies the Fibre Channel topology for both HICs on an array. Options are loop only (loop), point-to-point only (ptp), loop preferred (loop-ptp) or point-to-point preferred (ptp-loop).

Loop connects to either an FC-AL arbitrated loop or a fabric loop port (FL_Port) on a switch.

Point-to-point (ptp) connects to a direct fabric connection, such as an F port on a switch.

Loop-ptpallows the array to determine what kind of connection to use, but tries to connect in loop mode first, then point-to-point mode.

Ptp-loopallows the card to determine what kind of connection to use, but tries to connect in point-to- point mode first, then loop mode.

•FcDataRate specifies the Fibre Channel data rate at which both HICs on a Diamond operate. Choices are 1 gigabit, 2 gigabit and autodetection.
