Understanding stripe-unit size

The stripe-unit size is the amount of data written on a given disk before data is written on the next disk. To maximize the overall performance, choose a size that is close to the size of the system I/O request. The size of the system I/O request depends on your operating system. If you are not sure of the size, use the default setting.

Attention: After you configure an array and store data on the logical drives, you cannot change the stripe-unit size without destroying data in the logical drives.

You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. The default setting is 8 KB data bytes.
