Disabling caching
You can disable caching globally, by disabling caching on the virtual machine, or locally, by disabling caching for individual disks on the virtual machine.
About this task 
When you disable caching on the virtual machine, the cache is no longer "kept warm" for virtual disks. Cache data is discarded. If you want to stop caching but keep the cache warm, leave the cache enabled on the virtual machine and set the cache mode to Pass Thru.
Step 
1.
From the home page of the Flash Accel Management Console, click the wrench icon for the VM or disk on which you want to disable caching and select Cache State > Disable.
From the home page of the Flash Accel Management Console, select each VM or disk on which you want to disable caching and click Cache State in the Bulk Actions area of the home page. In the cache state dialog box, select the Disable radio button and click Submit.
From the home page of the Flash Accel Management Console, select each VM and disk on which you want to disable caching and click Cache State in the Bulk Actions area of the home page. In the cache state dialog box, select the Disable radio button and click Submit.
Click the wrench icon for a VM and select Advanced to enable or disable caching, set the cache mode, and enable or disable cache metrics in the same step.
Result 
The Cache State field for the virtual machines and disks is set to Disabled.
After you finish 
Remember that disabling caching on a virtual machine effectively disables caching on all its disks. If caching seems not to be working properly for a disk, make sure that caching is enabled on both the disk and the virtual machine.
