if
you want to set the following, then click

:
- Array Chunk Size: The default is 64 KB. The chunk size is the
amount of contiguous data that is written to an array member
before moving to the next member of the array. To determine
the appropriate chunk size, refer to your operating system
documentation. For example, the default chunk size for
Windows NT and many other operating systems is 64 KB. If you
are using the array for a database with very small records, you
may want to use a smaller chunk size.
- Preferred Array Owner: Select the SM you want to own this
array. If you do not make a selection here, SAM automatically
selects the owner and balances the number of arrays each SM
owns. In most situations, which SM owns the array does not
matter. A single SM has ownership of arrays and dedicated
spares. When an SM fails, the other SM assumes temporary
ownership of its resources.
