Refer to the sample illustration to see how an ID range is assigned.
Device ID Ranges
Drive Slots and Sample IDs Assigned
NOTE: Odd numbered drive slots are assigned to Channel 0 and even numbered
drive slots are assigned to Channel 1 of the RAID Controller. This allows
for improved performance throughput.
1 Locate the switches on the SES Controller card and set them as described for
the specific range needed.
2 If you have daisy-chain expansion enclosures, set their SES Controller card
switches to the next available range of IDs, as needed.
For example, if you have two enclosures installed, the first is a NexStor 4210F
with a single RAID Controller (master) and the second daisy-chain enclosure
is a NexStor 4000F JBOD system (slave). Set the master RAID enclosure to
IDs 0 - 11, and the daisy-chain slave enclosure to IDs 16 - 27.
