Prerequisites for Configuring Nytro XD

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

*

The cache device must be a Nytro WarpDrive card.

*

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

*

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

*

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

*

On the Linux platform – root, swap, boot -

*
