HP c-Class Vmware manual Using the IO Accelerator as swap with ESX

Page 21

An ESXi host has the following:

Memory capacity of 36,852 MB

Total IO Accelerator device datastore capacity of 320 GB (or approximately 320,000 MB). 320,000 MB device capacity * 0.5% of device capacity approximately 1600 MB of RAM equivalent. 36,852 MB total memory capacity - 1600 MB free = 35,252 MB of memory limited to the host.

The new value under Limit in Memory Resources is 35,252 MB.

Using the IO Accelerator as swap with ESX

The IO Accelerator cannot be used as a swap device for the ESX or ESXi host.

However, the IO Accelerator can be used as swap for virtual machines. To use the IO Accelerator as swap for a virtual machine:

1.Go to VMware vSphere Client > Configuration > Virtual Machine Swapfile Location.

2.Indicate the appropriate Datastore location as the virtual machine swapfile location.
