DS8000® series storage systems are designed to be fast and manage heavy I/O.
About this task
A DS8000 series
storage system can be configured in RAID 5 and RAID 10 arrays. The
quantity of disk units in an array is fixed. Stripe or segment sizes
are set automatically. You cannot tune cache for a DS8000 series storage system; for example,
you cannot disable cache for the LUNs that are used for the server
database. The inability to tune cache is usually not a problem because
these systems typically have large amounts of cache.
