Abstract
A Non-Volatile Memory express (NVMe) node includes a memory used at least in part as a shared cache in a distributed cache. At least one processor of the NVMe node executes a kernel of an Operating System (OS). A request is received from another NVMe node to read data stored in the shared cache or to write data in the shared cache and an error detection operation is performed on the data for the request using the kernel. In another aspect, the kernel is used to perform Erasure Coding (EC) on data to be stored in the distributed cache. A network controller determines different EC ratios based at least in part on indications received from NVMe nodes of frequencies of access of different data and/or usage of the distributed cache by different applications. The network controller sends the determined EC ratios to the NVMe nodes.
