Why would an administrator consider placing both disks on the same datastore (Choose Two)?

A virtual machine has been configured with N-Port ID Virtualization. The Guest OS virtual disk is placed in a RAID5 datastore, while the Production virtual disk is placed in a RAID1+0 datastore. Why would an administrator consider placing both disks on the same datastore (Choose Two)?

    NPIV Capabilities and Limitations
    Learn about specific capabilities and limitations of the use of NPIV with ESXi.

    ESXi with NPIV supports the following items:

    ■ NPIV supports vMotion. When you use vMotion to migrate a virtual machine it retains the assigned WWN.

    If you migrate an NPIV-enabled virtual machine to a host that does not support NPIV, VMkernel reverts to using a physical HBA to route the I/O.

    ■ If your FC SAN environment supports concurrent I/O on the disks from an active-active array, the concurrent I/O to two different NPIV ports is also supported.

    When you use ESXi with NPIV, the following limitations apply:

    ■ Because the NPIV technology is an extension to the FC protocol, it requires an FC switch and does not work on the direct attached FC disks.

    ■ When you clone a virtual machine or template with a WWN assigned to it, the clones do not retain the WWN.

    ■ NPIV does not support Storage vMotion.

    ■ Disabling and then re-enabling the NPIV capability on an FC switch while virtual machines are running can cause an FC link to fail and I/O to stop.
