Abstract: A method may include receiving, from a process, a memory allocation request for a memory system comprising a first channel having a first channel utilization and a second channel having a second channel utilization, selecting, based on the first channel utilization and the second channel utilization, the first channel, and allocating, to the process, a page of memory from the first channel. The selecting may include selecting the first channel based on a balanced random policy. The selecting may include generating a ticket based on a random number and a number of free pages, comparing the ticket to a number of free pages of the first channel, and selecting the first channel based on the comparing. The selecting may include selecting the first channel based on a least used channel policy.

Abstract: A method and redundant array of independent disks (RAID) system are provided. An operation is received from an application at a file system (FS) of the RAID system. A memory mapping module of the RAID system receives at least an FS logical block address (LBA) in accordance with the operation. The memory mapping module creates a mapping from a virtual memory of the application to a RAID array in a system memory of the RAID system using at least the FS LBA.
