� Other Interfaces Other interfaces need to be connected to both controllers. For example, in the event of single controller failure, terminal emulation through the IFT-9535 cable will be continued by an existing controller without user's intervention. 12.1.2 Grouping Hard Drives and System Drive Mapping A Logical Drive (logical configuration of drives) consists of a group of SCSI drives. Drives in one logical drive do not have to come from the same SCSI channel. Each logical drive can be configured a different RAID level and several logical drives can be used to compose a larger logical volume. Figure 12 - 3 Grouping Hard Drives Drive Channel 0 4 GB Drive Channel 1 ID 5 ID 0 ID 3 ID 2 4 GB RAID 5 8GB 4 GB Logical Drive 0 4 GB 2 GB ID 6 ID 1 ID 0 ID 14 Global Spare Drive Redundant Controller 12-3 2 GB 2 GB 2 GB RAID 0 6GB Logical Drive 1 Local Spare Drive of LD1 While grouping physical drives together, another drive can be assigned as the Local Spare Drive to one specified logical drive, or as the Global Spare Drive. A Local Spare is taken to rebuild one logical drive while a Global Spare participates in the rebuild of any logical drive in a RAID system. You may divide a logical drive into several partitions as diagrammed below, or use the entire logical drive as one single partition.
12-4 Figure 12 - 4 Partitioning Logical Units RAID 5 8GB Logical Drive 0 RAID 0 6GB Logical Drive 1 Partition 0 - 2GB Partition 1 - 1GB Partition 2 - 5GB Partition 0 2.5GB Partition 1 1.5GB Map each partition to a host SCSI ID (Primary or Secondary ID). You may have to create Primary and Secondary IDs separately on host and drive channels if these IDs are not available. The configuration procedure will be discussed in section "12.3." Partitions mapped to a Primary ID (meaning that the partition has been assigned to the Primary controller) will be managed by the Primary controller, and those mapped to a Secondary ID the Secondary controller. Each SCSI ID (or LUN under ID) will act as one individual hard drive to the host computer virtually. Figure 12 - 5 Mapping System Drives (LUNs) Infortrend
