Task 4: Installing Disk Drives

You can populate the VessRAID with SAS or SATA hard disk drives. For optimal
performance, install physical drives of the same model and capacity. The drives'
matched performance allows the logical drive to function better as a single drive.
The table below shows the number of drives required for each RAID level.
Level
RAID 0
RAID 1
RAID 1E
RAID 5
* Must be an even number of drives.
Drive Slot Numbering
You can install any suitable disk drive into any slot in the enclosure. The diagram
below shows how VessRAID's drive slots are numbered. Slot numbering is
reflected in the WebPAM PROe and CLU user interfaces.

airflow, even if you do not populate all the carriers with disk drives.
