NEC Storage VirtualCachePartitioning supports a function to partition cache memory of storage into multiple cache segments. This function provides high stability in the virtual environment by setting limits to cache memory of the storage for each tenant to secure the I/O bandwidth.

The following benefits are achieved by installing the function.

Stability in the virtual environment

Stability is ensured by eliminating impact across the tenants in the virtual environment.

Elimination of impact on performance of ongoing operations due to addition of new tenant

New tenant can be added without having impact on performance of ongoing operations.

Elimination of impact on performance of ongoing operations due to data growth

Even if data grows in certain operations, I/O bandwidth can be expanded without having impact on performance of other operations while stability is ensured.
