For example, /dev/sda in Linux.
Supported/Eligible Logical Drives
DAS or SAN accessed storage can be accelerated with Nytro XD. Nytro XD also implements the write through operations. This means that the cache content is always coherent with the storage that Nytro XD is accelerating.
A configuration with multiple servers accessing the SAN storage is supported in these circumstances: when high availability is a requirement, a primary and secondary server might access the same partition, but not concurrently. If the primary server fails over to a secondary server, data located in the SAN accessed storage is always valid, because of write through, and the application can begin operation on the secondary server. To meet the service level expectations, let the secondary server also use Nytro XD. If a fail over occurs, the Nytro XD cache in the failed primary server is not coherent with the SAN storage. When fail back is implemented, to ensure cache coherency, first restart Nytro XD (see Starting and Stopping Nytro XD on Linux and Starting and Stopping Nytro XD on Windows).
