Abstract
A Software Defined Network Attached Storage (SDNAS) executes on a storage system to provide access to shared file systems, referred to as “shares”, on the storage system. Users access the shares using protocol clients. A share priority table is maintained by the SDNAS and used to specify share priorities on the storage system. A share priority adjustment process is used to dynamically adjust the share priority values based on average usage values computed using a weighted usage function, and optionally based on limited ranges. The weighted usage function considers the average number of protocol client connections on the share, the average number of read operations on the share, whether the share supports continuous availability, and other factors. The adjusted share priority values are used to specify IO priorities which used by the operating system scheduling mechanism to schedule the IO operations and to establish CPU priorities for the IO operations.
