1.9 Ordering HS Array Controller Cache Modules
A 16- or 32-MB read cache module or 16- or 32-MB write-back cache module can
be ordered with an HS array controller. The write-back cache module must be
ordered if you wish to use RAID functionality.
Note
Remember that options and upgrades have different order numbers.
You can choose between a 16- or 32-MB read cache, or 16- or 32-MB
write-back cache option when you place your controller order. Separate
upgrade kits with their own part numbers are available when you are
ready to upgrade your existing cache modules.
