Creating and Modifying Logical Devices

A logical device is created by grouping disk drives together to form a virtual storage unit. Each logical device includes RAID (the RAID level depends on how many disk drives are in the logical device) and can also include a hot spare for an additional level of data protection.

Once a logical device is created, you can use Adaptec Storage Manager to increase its capacity, change its RAID level, and make other modifications.

Note! Adaptec Storage Manager allows you to combine hard drives and Solid State Drives (SSDs) in a RAID 1 or RAID 10 logical device. This type of logical device is called hybrid RAID. Hybrid RAID improves performance by sending read operations to the fastest path first—the SSD. You can use any SSD (or available segment) when creating or modifying a hybrid RAID logical device, unless it is part of the maxCache pool.
