Therefore, if there are 5 switches in the Fabric SES reports 6 LUNs, one LUN value for each

switch and LUN0 for the local client connection.

Other SCSI-3 enclosures can also run SES outside the Fabric, such as JBODs, RAID-5 arrays,

SCSI-3 hard drives, and SCSI-3 tape drives. These devices are identiﬁed by their Fabric and

SCSI addresses, and are assigned LUNs using standard SCSI-3 host adapter LUN addressing.

Note: It is not this guide’s intent to describe the environment outside of the Fabric.
