Vertical Expansion
To vertically expand a volume, you must replace all disks in the volume with larger-capacity
disks of the same physical performance level (disk type and speed). You can vertically
expand volumes with RAID 1, RAID 5, RAID 6, or RAID 10.
disks of the same physical performance level (disk type and speed). You can vertically
expand volumes with RAID 1, RAID 5, RAID 6, or RAID 10.
For example, you can expand an existing volume in a RAID 6 set that consists of four 500
GB
SATA 7,200 rpm disks by replacing all four disks with 750 GB SATA 7,200 rpm disks.
To vertically expand a volume:
1.
Replace one disk in the volume with a larger-capacity disk.
For more information about how to add a disk to your system, see the hardware manual
for your system, which is available at

Note:
You must use supported disks in your ReadyDATA system. For more

2.
Wait for the volume to resync your data.
You can continue to use your ReadyDATA system while the volume is resyncing.
Resyncing can take several hours. The start and completion of the resyncing process is
recorded in the system log (see

larger-capacity disk.
Configure Write and Read Boost Disks to Improve Performance
To enhance the performance of an existing volume and improve I/O operations, you can add
one or more high-performance disks such as SSDs to unload write (log) or read (cache)
operations, or both. You can easily remove write and read disks from a volume. For write and
read operations, you would not need to select disks with very large storage capacities.

You can attach both write and read disks to a volume:
•
Write boost. Assign one or more separate write disks to improve the write performance
