Enclosure Setup
You must select either mode using the CLI utility and re-start the 6Gb/s SAS JBOD enclosure.
The default is Normal Mode. Change the mode while 6Gb/s SAS JBOD enclosure is on. This
will not affect expander operation until 6Gb/s SAS JBOD enclosure is rebooted.
In normal mode, a SAS host can communicate with all drives in 6Gb/s SAS JBOD enclosure.
6Gb/s SAS JBOD enclosure contains expander ports. Expander ports can be attached to SAS
initiator ports, SAS and/or SATA target ports, and other expander ports. The SAS RAID
controller card or host adapter supports daisy-chain. The number of the 6Gb/s SAS JBOD
enclosures that can be supported depends on the RAID controller card or the host adapter
firmware. The following figure shows the connections of 6Gb/s SAS JBOD enclosures with
external mini-SAS data cables and SAS RAID controller card.
In zone mode, 6Gb/s SAS JBOD enclosure can be split into up to 8 virtual groups. Each
group’s drive channels and external cable connectors are assigned by CLI GROUP command.
The following figure shows 6Gb/s SAS JBOD enclosure that is split into 2 virtual groups. Each
group’s drive channels are controlled by individual host adapter using SAS CH1 and SAS CH2.
