Modular Server System Service Guide
If a hard drive is available, the drive size is displayed. Selected drives are highlighted
in green with the drive size displayed on each of the drives. Hard drives that are either
included in an existing storage pool or configured as a hot-spare drive cannot be
selected on this screen and are considered unavailable. Unavailable drives are
displayed as darker than the available hard drives and do not have the drive size
displayed on the image. The highlighted drive carriers identify the physical hard
drives that have been selected for the storage pool. In this example (see Figure 57),
drives 1, 2, 3, and 4 are selected.
5. Verify that the overall storage pool capacity and available RAID level options
supported by the number of physical drives selected meets your storage requirements.
The Pool Capacity displays the total available storage space for the new storage pool.
In Figure 57, four 67 GB hard drives are selected to be grouped together to create a
single storage pool with a Pool Capacity of 268 GB.
The RAID level options are determined based on the number of hard drives selected
for the storage pool. In Figure 57, four hard drives are selected. The RAID levels
supported by grouping hard drives 1, 2, 3, and 4 together as a single storage pool are:
0, 5, 6, 10, and 1E. RAID levels that are not available are displayed in light gray text.
In this example, RAID levels 1, 50, and 60 are grayed out. It is important to note that
the RAID level is not assigned to a storage pool. Instead, it is assigned to the virtual
drives within a storage pool. This enables a single storage pool to support many
virtual drives with different RAID levels.
