Abstract
Increased fairness for small vs large NVMe IO commands for accessing a non-volatile memory namespace provided by a network attached storage appliance can be realized by placing NVMe submissions received by a NVMe SQ on a first fabric queue set or a second fabric queue set based on a fairness policy. The first fabric queue set accesses the namespace via a first fabric connection. The second fabric queue set accesses the namespace via a second fabric connection. Accessing the namespace via the fabric connections results in NVMe completions that are merged from the fabric queue sets onto an NVMe completion queue. A process producing the NVMe submissions and receiving the resulting NVMe completions may be unaware of the multiple fabric queue sets.
