Explanation

TPSTUN is a VAAI primitive that enables the array to notify vSphere when a LUN is running out of space due to thin provisioning over-commit. The command causes suspending all virtual machines on that LUN. XtremIO supports this VAAI primitive. Incorrect Answers: C: The XtremIO features for VAAI support include: Clone Blocks/Full Copy/XCOPY Used for copying or migrating data within the same physical array (VMware term: HardwareAcceleratedMove). On XtremIO, this allows VM cloning to take place almost instantaneously, without affecting user I/O on active VMs. D: The XtremIO features for VAAI support include: Zero Blocks/Write Same Used for zeroing-out disk regions (VMware term: HardwareAcceleratedInit). This feature provides accelerated volume formatting.
