Technologies for efficiently managing allocation of memory in a shared memory pool

(57) Abstract

Technologies for efficiently managing the allocation of memory in a shared memory pool include a memory sled. The memory sled includes a memory pool of byte-addressable memory devices. The memory sled also includes a memory pool controller coupled to the memory pool. The memory pool controller receives a request to provision memory to a compute sled. Further, the memory pool controller maps, in response to the request, each of the memory devices of the memory pool to the compute sled. The memory pool controller additionally assigns access rights to the compute sled as a function of one or more memory characteristics of the compute sled. The memory characteristics are indicative of an amount of memory in the memory pool to be used by the compute sled and the access rights are indicative of access permissions to one or more memory address ranges associated with the one or more memory devices.
