A customer has a large ESX server environment they are considering deploying to XtremIO for a VDI implementation. To determine a baseline of the environment, you are proceeding with documenting each server's CPU, NIC, and disk utilization statistics. The customer has provided you with direct CLI access to the servers to conduct this assessment.
Which utility should be used to monitor these performance parameters?
resxtop is a command to retrieve performance statistics. This command is included in vSphere command line interface (CLI) and is part of the vSphere Management Assistant (vMA), which is an equivalent to esxtop that runs only inside an ESX service console.

An administrator receives an error on an XtremIO array while performing snapshot refreshes to a production volume. What is a potential cause for this issue?
The workflow for refreshing XtremIO Snapshots, containing Oracle Database files, consists of the following five simple steps:
1. Shut down the database instances with files in the target Snapshot Set.
2. Dismount the ASM disk group (or file systems) involved.
3. Refresh the Snapshot via XtremIO GUI (or CLI or RESTful API).
4. Mount the ASM disk groups (or file system) involved.
5. Start the database instances.
This entire workflow is measured in seconds (not minutes).
