Prerequisites for using Flash Accel : Host system requirements

Host system requirements
The ESXi server that hosts the flash device and virtual machines must meet minimum resource requirements. Review these requirements before installing the Flash Accel Host Agent.
Note: The ESXi host must have an acceptance level of PartnerSupported. This is the default acceptance level for ESXi hosts.
Note: Hosts must have DNS mappings. Flash Accel cannot discover hosts that do not have DNS mappings.
Flash Accel requires additional RAM to support the size of the installed flash device. The rule of thumb is to configure 0.0035 GB of physical RAM for every GB of device memory. So if you have installed a 1 TB SSD as the cache device, you should configure an additional 3.5 GB of physical RAM in the server.
