RAID Planning
2.1 Considerations
1. How many physical drives do you have?
2. How many drives on each drive channel?
5. Dual loop, hub, or switch?
3. How many drives would you like to appear to the host computer?
4. What kind of host application?

5. The next step is to make logical drives or storage partitions available through the host ports. When associated with a host ID or LUN number, each capacity volume appears as one system drive. The host SCSI or Fibre adapter will recognize the system drives after the host bus is re-initialized

A drive enclosure usually has drive slots pre-assigned with specific IDs. There are occasions when an ID needs to be assigned manually to a device other than an ID provided otherwise. The set slot number and the add drive entry functions are reserved for Infortrends Fault-bus operation

View and Edit Drive-Side Parameters 2. Drive-Side Dual Loop
Controller Unique Identifier
Controller firmware automatically examines the node names and port names of all the connected drives once initiated. If devices on two different drive channels appear with the same loop ID and port name, controller will consider these two drive channels as a dual loop
Controller Communications over Fibre Loops
2. Communications Traffic Distributed over All Drive Loops Select all drive loops and configure them as Drive + RCCOM Drive Loops plus Redundant Controller Communications. The communications traffic between the two controllers will be automatically distributed over all drive loops
