Getting started with Flash Accel : Installing Flash Accel Host Agents

Installing Flash Accel Host Agents
Flash Accel Host Agents manage caching functionality on ESXi hosts. You should install the Host Agent on each host where you have installed a flash device. You can install the agent on a single host, or use a bulk install to install agents on multiple hosts.
Before you begin 
ESXi hosts must be in maintenance mode before you can install Flash Accel Host Agents. All running virtual machines must be migrated to another host (either manually or automatically by DRS) or shut down. You can then right-click the host using the vSphere Client and select Enter Maintenance Mode.
Note: The ESXi host must have an acceptance level of PartnerSupported. This is the default acceptance level for ESXi hosts.
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.
About this task 
It is almost always best to install the flash device before installing the Flash Accel Host Agent, but you can install the flash device afterward if you prefer.
Steps 
1.
From the Host Inventory page of the FAMC, click the wrench icon for the host on which you want to install Flash Accel software and select Software > Install.
From the Host Inventory page of the FAMC, select each host on which you want to install Flash Accel software and click Host Agent Install in the Bulk Actions area of the FAMC.
The host installation dialog box opens.
2.
Click Install.
Result 
The Flash Accel Host Agent is installed on the host.
After you finish 
You must take ESXi hosts out of maintenance mode before you can initialize the flash device. In the vSphere Client, right-click the ESXi host and select Exit Maintenance Mode. You can then power on the VMs on the host, or if you had moved them to another host, move the VMs back over to the host.
