Re: Fast cache performance

Hi everybody

we have a vnx 8000.we are working on sizing.now we have some SAS and NL-SAS disks.we want to use fast cache, too.

I calculate SAS and NL-SAS effective IOPS.but I couldn’t find any calculator for FAST cache IOPS.Is it the same as SAS and NLS SAS Formula?

1-I want to know how much percentage of IOPS will increase with the help of FAST Cache?

2-Is there any calculator for fast cache IOPS?

3-How much Fast Cache Capacity should I consider?

4-How much IOPS will handle by SP Cache which is 128GB for vnx 8000 per sp?

thanks
