4.6.1.7 Cache Mode:

The RAID subsystem supports “Write-Through” and “Write-Back” cache.

4.6.1.8 Tag Queuing:

The “Enabled” option is useful for enhancing overall system performance under

multi-tasking operating systems. The Command Tag (Drive Channel) function

controls the SAS command tag queuing support for each drive channel. This function

should normally remain “Enabled”. “Disabled” this function only when using SAS

drives that do not support command tag queuing.

4.6.1.9.1 SAS Port/LUN Base/LUN

Single Controller SAS Port:

(for Yotta 3 E Series & Yotta 3 Tower Series)

Two 4-port SAS ports can be applied to the RAID subsystem. The RAID subsystem

supports Port 0, 1 and 0&1 cluster option. If you configure the Host/JBOD port as a

JBOD function on the “System Config”, then there will be no function on the selection

of ‘0, 1’ and “0&1 Cluster” option.
