Using Dolpin dis_nvme driver

Hint

The Dolphin dis_nvme driver is not yet publically available. Contact support if you’re interrested!

Load the dis_nvme manager on one of the cluster nodes. On all nodes that will need access to the drive, load the dis_nvme client module. The modules will automatically discover all available NVMe drives and all nodes will get a new /dev/disnvme### for each available NVMe drive. At this point you can use the NVMe drives as any other shared disk. Note that dis_nvme only provides shared access to the drives and that a shared-disk filesystem must be used to allow shared access to a single filesystem.

System Requirements

• The cluster nodes must be a supported platform.

• The cluster nodes must run a supported operating system.

Additional System Considerations

• The NTB prefetchable size on the lender limits the amount of RAM the NVMe drive can access at any given moment. A small prefetchable size can negatively impact performance.
