Note that your fingers may not be caught or hit on some object when your
hands are entered into the disk array unit.
Do not disassemble or modify the cache memory. Failure to follow it may
cause the unit to be defected.
The disk array unit is normally equipped with a single 256MB cache memory on each
controller.
To use an additional control card or to use larger capacity of cache memory for improving
the feature of the disk array unit, up to four cache memories can be added for each
controller and additional control card.
Product name: Additional 512MB cache memory
Part number: NF2300-SC01E
Product name: Additional 1GB cache memory
Part number: NF2300-SC02E
Cache memories with different capacities may coexist in a specific
controller. However, The cache memory installed on a slot, one of CHE0
to CHE3, of CONT0 must have the same capacity as that on the
corresponding slot of CONT1.
The additional control cards installed in CONT0 must have cache
memories with the same capacities as those installed in CONT1 at the
corresponding slots (CHE4 to CHE7). However, their locations and
capacities may not be the same as those of the cache memories in the
controller.
Install cache memories on the slots sequentially in the ascending order of
slot numbers if they are installed.
NF2300-SC01E and NF2300-SC02E are composed of two 256MB cache memory cards
and two 512MB cache memory cards, respectively. Install a single cache memory card for
each of two controllers or two additional controllers.
