Installing and Setting up Fluid Cache
NOTE: When installing and setting up Fluid Cache, you must restart the server multiple times.
Enabling SSH on the ESXi Host
To enable SSH on the ESXi host, perform the following steps:
1. In the vSphere Windows client, select one of the servers in the Fluid Cache cluster.
2. In the Configuration tab, go to Software → Security Profile.
3. In the Security Profile Services box, select Properties.
The Services Properties window is displayed.
4. In the Services Properties window, go to the SSH label, and under Service Properties, select
Options.
The SSH (TSM-SSH) Options window is displayed.
5. Make sure that the Start tab is grayed out. If not, click Start, and then click OK.
6. Repeat this process for all servers in the Fluid Cache cluster.
Marking Devices for Passthrough
Fluid Cache requires a direct (“passthrough”) connection between the VSA and the cache devices,
bypassing ESXi itself.
1. In the vSphere Windows client, select one of the hosts in the Fluid Cache cluster.
2. In the Hardware area of the Configuration tab, click Advanced Settings.
The DirectPath I/O Configuration window is displayed.
3. In the DirectPath I/O Configuration window, select Edit.
The Mark Devices for Passthrough window is displayed.
4. In the Mark Devices for Passthrough window, select the first cache device.
Cache devices compatible with Fluid Cache contain either “Micron RealSSD” or “Samsung
Electronics” in their name.
5. Read and acknowledge the warning message, and then click Yes.
6. Repeat steps 4 and 5 for each cache device in the cluster.
7. Click OK.
8. Restart the host.
NOTE: You do not need to restart the host at this time if you are continuing with the following
procedure, Configuring the Network Adapters. The passthrough connection is enabled when
the host is restarted at the conclusion of that procedure.
9. Repeat this procedure for all hosts in the Fluid Cache cluster.
