Can i reduce memory used by SP on VNX53000?

I have VNX 5300 and SPs used 5638mb of 8192mb memmory.

I have only 2554mb for read and write cache.

Can i reduce memory used by SP and increase R/W memory?

Thank you.

If you have enablers installed that you dont use like FAST VP, Thin, compression – then de-install them

Looking at your number you probably have FAST Cache installed – which needs some memory as well.

Or you can change the ratio of write to read cache

Yes,

I have a lot of enablesrs(14) installed on my system.

So there is no way to set up cache?

SP use as much as is necessary and can be set to use less?

depending how much you have left after your enablers are installed you can only decide how to divide whats left between read and write cache.

What are you trying to achieve by reducing the amount of cache ?

the SP's reserve an amount of cache for internal use also so you cannot assign any "extra" cache to the sp
