Prerequisites for Configuring the Nytro XD Solution

> Prerequisites for Configuring the Nytro XD Solution

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

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

> | The cache device or sub node is not used as an active system device, on OS installation drive.

> | The cache device or the underlying partition is not used as an active system device,–root, swap, boot.

> 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 VDs qualify for caching if these conditions are fulfilled:

> | The VD is an SCSI device.

> | When the VDs are using a SAN, they cannot be shared between multiple servers where the data can be modified by all servers.

> | The VD must not be removable (USB, CDROM, or so on).

> | The VD is not a Nytro WarpDrive card.

> | The individual partitions cannot be added as target devices (on Windows). The VD must be a parent node (DISK0) and not a partition (C:, D:)

> | The individual partitions cannot be added as target devices (on Linux). The VD must be an unpartitioned device (/dev/sdX) and not a partition (/dev/sdX1).

> | The VD or any of the underlying partitions are not under LVM.
