Administrator Guide

a. In the Storage view, select the Fluid Cache cluster. (Do not select Storage Center or its contents.)
b. In the Summary tab, locate the server in the Servers section.
c. Right-click the server and select Remove Server from Cluster.
d. When asked to confirm the action, click OK.
After the system processes for some time, the server reappears outside of the cluster in the
Servers area. You may need to manually refresh the display.
NOTE: After powering down the VSA on an ESXi host and then removing the ESXi host from a
cluster, you must reinstall the VSA to add the server to any cluster, including the cluster from
which it was removed.
Adding Cache Devices to a Fluid Cache Cluster
1. Log in to Enterprise Manager as a user with Administrator or Volume Manager privileges.
2. In the Storage view, expand Fluid Cache Clusters if necessary, and then right-click the Fluid Cache
cluster. (Do not right-click Fluid Cache Clusters itself.)
3. Click Tasks → Add Devices to Cluster.
The Add Devices to Cluster window is displayed. By default, all available devices compatible with
Fluid Cache are selected.
4. Clear the option next to unwanted cache devices or click the Unselect All option, and then select the
cache devices to be added. (Click the Select All option to use all available cache devices again.)
CAUTION: Any existing data on a cache device is lost when the device is added to the Fluid
Cache cluster. Back up this data before proceeding.
5. Click OK.
The devices now appear in the list in the Devices section.
Setting Storage Capacity for each Cache Server
The Fluid Cache VSA OVA is shipped with a default memory size of 24 GB, and it is sized for a maximum
of 1.6 TB of cache per node for a 9-node cluster.
The maximum SSD storage capacity supported is 3.2 TB per node. However, the size of the cache devices
on a fluid cache node affects the memory utilization of that server node. The number of nodes in the
cluster also affect the memory utilization.
Therefore, if you want to use more than 1.6 TB or 3.2 TB of cache memory per node, it is recommended
to increase the memory of the VSA to 34 GB, which will support maximum of 3.2 TB per server node.
If you want to use less than 1.6 TB, it is recommended to not to change the default VSA memory size.
The following procedure provides steps on how to increase the size of a Fluid Cache VSA using VMware
vSphere client:
1. Right-click the Fluid Cache VSA and select Power → Shut Down Guest.
2. Right-click the Fluid Cache VSA and select Edit Settings.
3. Click the Hardware tab, and click Memory.
4. In the Memory Configuration section, in the Memory Size field, change the memory size from
24000 MB to 34000 MB.
5. Click the Resources tab, and click Memory.
