The “RESCUE” function can recover the missing RAID set infor-

mation. The RAID controller uses the time as the RAID set signa-

ture. The RAID set may have different time after the RAID set is 

recovered. The “SIGANT” function can regenerate the signature 

for the RAID set.

A volume set is seen by the host system as a single logical device. 

It is organized in a RAID level with one or more physical disks. 

RAID level refers to the level of data performance and protection of 

a volume set. A volume set capacity can consume all or a portion 

of the disk capacity available in a RAID set. Multiple volume sets 

can exist on a group of disks in a RAID set. Additional volume sets 

created in a specified RAID set will reside on all the physical disks 

in the raid set. Thus each volume set on the RAID set will have its 

data spread evenly across all the disks in the RAID set. 

1. Volume sets of different RAID levels may coexist on the same 

raid set.

2. Up to 16 volume sets can be created by the SATA RAID control-

ler.

3. The maximum addressable size of a single volume set is not 

limited to 2 TB because the controller is capable of 64-bit mode.  

However, the operating system itself may not be capable of ad-

dressing more than 2 TB. See the Areaca website for details.
