nodes. Even though you can use the rotary switch to select JBOD mode for any node in a

cascaded configuration, only the first JBOD volume of any subordinate node is detected by your

host. Therefore, selecting JBOD mode for any subordinate node is not recommended.

In a JBOD configuration, the CoolMax CD-320 directly exposes each physical drive.

FAST

The FAST storage policy distributes access across all hard disks, also called striping (equivalent

to RAID 0). FAST presents the best data speed but no data redundancy. FAST storage policy

accelerates hard disk operating speed by using many disks in parallel. Hard drive data segments

are written to different disks simultaneously which increases performance while sacrificing data

redundancy.

To implement the FAST storage policy, the CoolMax CD-320 creates a single virtual volume

that is striped across both hard drives, with a storage capacity that is equal to the sum of both

hard disk drives.

It is possible to set any node within a cascaded configuration to FAST, although there is no

performance benefit when using multiple layers of striping.
