[Lustre-discuss] How does lustre deal with different types of media (ssd, sata, tape)

[3piece]

I would like to make a SAN implementing lustre but want to know how it
deals with different kinds of storage media such as SSD, SATA disks and
Tape(Or possibly cloud storage)?

I'm sure I understand exactly what you are trying to do but as far as
storage is concerned, as long as whatever storage you want to use for
your Lustre filesystem is abstracted as a block device on Linux, Lustre
can use it.

Lustre allows to group block devices into pools. This feature enables Lustre administrator to create policies for file striping, for example based on the storage media types.
