Chapter 2: VessRAID Installation
15
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.
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.
Figure 9. VessRAID drive slot numbering
Install all of the drive carriers into the VessRAID enclosure to ensure proper
airflow, even if you do not populate all the carriers with disk drives.
