![]() The good news is that most virtualized server environments are slightly more read-heavy 60% reads are common. Most caching solutions that operate in the VMware environment are read only, meaning that the write portion of I/O drops through the cache and onto the intended storage medium - in most cases, a shared hard disk. This means that subsequent reads actually come from the SSD in the server, not from mechanical hard drives on the other side of the storage network. Caching automatically moves the most active portion of data from the SAN or local DAS storage and into the SSD in the server. ![]() Server-side SSD eliminates potential bottleneck of the storage network and places high-performance storage directly in the hosts that need it most.Ĭaching is the most common choice to add to the server-side SSD to automate the use of this high-performance tier. Implementing solid state disk (SSD) in a VMware host server has become a popular option to maximize the return on solid state investment.
