Scenario: A customer needs to configure a XenDesktop environment so that an end user has the best experience when launching a virtual desktop. The environment needs to be configured with fault tolerance so that when a XenServer goes down for maintenance the target device can still be deployed by any XenServer with the least load.
Currently, the customer has a XenServer pool consisting of 16 XenServer hosts with 8 GB of memory and a 2 TB SATA hard disk A 2 TB Fibre Channel Storage Area Network is attached to the XenServer. The Provisioning services host is configured on a stand-alone server with 8 GB of memory and three 500 GB SCSI hard disks configured as a RAID 5 configuration. What is the best write caching method for deploying 800 target devices within a XenServer pool?
A. Cache on the target device and redirect to the RAM of the target device.
B. Cache on the Provisioning services host and redirect the cache on the local file system.
C. Cache on the target device and redirect the cache on a share within the Fibre Channel storage repository.
