Prerequisites for Configuring Nytro XD

The following prerequisites are common to both cache devices and VDs for a device to be configured in Nytro XD:

*

The cache device or any of its sub-nodes are not mounted.

*

The cache device or sub nodes are not used as an active system disk.

*

On the Linux platform: – root, swap, boot

*

On the Windows platform: OS installation drive

Nytro XD qualifies the cache devices if these prerequisites are fulfilled:

*

The cache device must be a Nytro WarpDrive card.

*

The cache device must not be a root or boot device.

*

The cache device must not be partitioned.

The logical drives (VDs) qualify for caching if these conditions are fulfilled:

*

The logical drive is a SCSI device.

*

The logical drive must not be removable (USB, CDROM, or so on).

*

The logical drive is not a WarpDrive.

*

The individual disk partitions cannot be added as target devices. The logical drive must be a parent node (on the Linux platform: /dev/sdX - and on the Windows platform: DISK0), and not a partition (on the Linux platform: /dev/sdX1 and on the Windows platform: C:, D:).

*

The logical drive or any of the sub nodes is not an LVM on the Linux platform.
