Prerequisites for using Flash Accel : Virtual machine system requirements

Virtual machine system requirements
The virtual machine running an application that uses the cache must meet minimum resource requirements. Review these requirements before installing the Flash Accel Guest OS Agent.
Note: VMs must be pingable by Flash Accel. For best discovery results, VMs should have DNS mappings.
Flash Accel requires additional virtual machine memory to support the amount of cache allocated to the VM. The rule of thumb is to configure 0.0035 GB of additional memory for every GB of cache space allocated. So if you are planning to allocate 500 GB to the VM, you should configure an additional 1.75 GB of memory.
Flash Accel uses a physical Raw Device Mappings (pRDM) device to represent the cache to the virtual machine. The RDMP file for the device cannot be stored in an NFS datastore. If the files for the VM are stored in an NFS datastore, its host must have access to a VMFS datastore for the RDMP file.
