Parameters
Parameter Description
cacheBlockSize Specifies the cache block size used by the RAID
controller module for managing the cache. Valid
values are 4 (4 KB) or 16 (16 KB), the default
value is 4.
NOTE:
Typically, this parameter should not be
changed from the default. The default setting has
been set based on best performance for all
environments.
NOTE:
When defining cache block sizes, the 4-KB
cache block size is best suited for systems that
require I/O streams that are typically small and
random. The 16-KB cache block size is more useful
for systems that require large data transfer,
sequential, high bandwidth applications. This
parameter defines the cache block size for all
virtual disks in the storage array. For redundant
configurations, this parameter includes all virtual
disks owned by both controllers within the storage
array.
