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.
- When the stripe-unit size is
8 KB or 16 KB, the maximum number of physical drives in an array is 16.
- When the stripe-unit size is
32 KB or 64 KB, the maximum number of physical drives in an array is 8.
