Does LSI SAS2308  support capacity expanding by adding more physical disks...current configuration is RAID1 and RAID 5.

if not supported..can we add another RAID group or it only support two virtual disks?

Hello AhmedGomaa

LSISAS2308 or LSISAS3008 does not support the online capacity expansion of new disks to the original RAID group and does not support the online expansion of VD space.


And the LSI SAS2308 supports up to two virtual drives. One virtual drive supports a maximum of 10 hard drives, and two virtual drives support a maximum of 14 hard drives (that is, the sum of hot spare drives and hard drives in RAID arrays). The remaining hard drives can be managed by the LSI SAS2308 as independent physical drives.

Hi

Capacity expansion is possible


The capacity of a RAID array can be expanded using either of the following methods:

Add new hard drives to an existing RAID array.
Increase the available space of a RAID array if the capacity of all member hard drives in the RAID array is not fully utilized.

Only RAID 0, RAID 1, RAID 5, and RAID 6 support capacity expansion through hard drive addition.
RAID 10, 50, and 60 do not support capacity expansion through hard drive addition.
If a RAID array contains two or more virtual drives, its capacity cannot be expanded through hard drive addition.
