For best performance with most applications, each SP should have its maximum amount of cache memory and you should use the default settings for the cache properties. Analyzer shows how the cache affects the storage system, and lets you tune the cache properties to best suit your application.A storage-system cache has two parts: a read cache and a write cache. The read cache uses a read-ahead mechanism that lets the storage system prefetch data from the disk. Therefore the data will be ready in the cache when the application...
