In VSphere 5.0 and later, View Storage Accelerate (VSA) caches virtual machine disk data to EXSi hosts. It uses the content-based read cache (CBRC) in EXSi hosts, which no longer reads the entire operating system from the storage system. It reads the regular data block from the cache, thereby enhancing the performance of the virtual host.
