Usually when configuring cache settings for SP’s on VNX system, set read cache to roughly 10 percent of available cache; 200 MB is the minimum recommended and 1024 MB is the maximum recommendations…, Since you have mentioned that FAST Cache is enabled, when if FAST Cache is installed in the Storage System the existing SP read and write cache may need to be temporarily disabled to allocate space for the FAST Cache memory map. Once the memory map had been created, the resized SP read and write cache are automatically enabled by the storage system.
Please refer to the below mentioned document for more information page no 10 :
hi OPP_LTD . you have FAST Suite and in it Focus on Unisphere Analyzer . it will be your right hand in the Cache Decisions. it is ver important to understand how to Know the Key Featureas of its Benchmarks.
Which model of VNX are you working on? As mentioned in an earlier comment, SP Read Cache size ranges from 100MB to 1GB Max. Can you please elaborate what kind of recommendations are you looking for? On a higher level, your configurations looks ok. Just the Read Cache size needs to be configured according to the model.
