Enable Server Load Equalizing for Storage Center Volumes
Server load equalizing dynamically adjusts queue depth for volumes experiencing high IOPS to minimize the performance impact on
other volumes. Enable load equalizing on a
Storage Center that hosts Fluid Cache volumes to prevent cache ushing operations from
adversely aecting performance for other volumes.
About this task
NOTE: Enable load equalizing only for environments using Fluid Cache clusters, or if directed by Dell Technical Support.
Steps
1. Click the Storage view.
2. In the Storage pane, select the Storage Center.
3. In the Summary tab, click Edit Settings. The Edit Settings dialog box appears.
4. Click the Storage tab.
5. Select the Server Load Equalizer Enabled check box.
6. Click OK.
Troubleshooting
Follow the advice in one of the following topics to help determine the cause of an issue or solve an issue.
Unable to Recreate a Fluid Cache Cluster After a Hardware Failure
Use Storage Manager to completely delete a Fluid Cache cluster that has failed before trying to remake the cluster.
NOTE: Clean up Storage Manager and the Storage Centers after a hardware failure before recreating a Fluid Cache
cluster. The Delete option will not appear unless the Fluid Cache cluster has been fully removed from Storage Manager.

Cache Node is Not Listed
The node was not selected in the Select Servers window when creating the Fluid Cache cluster or the network switch may not be
congured correctly.
1. Make sure the node is selected.
2. If the node is still not listed, review the settings for the network switch and consult your switch documentation.

Unable to Select a Specic Caching Mode
The required number of nodes or PCIe SSDs may not be available.
Keep in mind that while a cache device or cache server may have been previously congured, it may have since failed or is impacted
by a network failure.
• For write-back caching, ensure that there is a minimum of two nodes with PCIe SSDs on dierent servers in the Fluid Cache
cluster.
• For write-through caching, ensure that there is at least one node with a PCIe SSD.
• Ensure the cluster is not in maintenance mode.
