Method And Memory Availability Managing Module For Managing Availability Of Memory Pages

摘要

A method and a Memory Availability Managing Module (110) “MAMM” for managing availability of memory pages (130) are disclosed. A disaggregated hardware system (100) comprises sets of memory blades (105, 106, 107) and computing pools (102, 103, 104). The MAMM (110) receives (A010) a message relating to allocation of at least one memory page to at least one operating system (120). The message comprises an indication about availability for said at least one memory page. The MAMM (110) translates (A020) the indication about availability to a set of memory blade parameters, identifying at least one memory blade (105, 106, 107). The MAMM (110) generates (A030) address mapping information for said at least one memory page, including a logical address of said at least one memory page mapped to at least two physical memory addresses of said at least one memory blade (105, 106, 107). The MAMM (110) provides (A050) at least some of the address mapping information for use when access to said at least one memory page is requested. A corresponding computer program and a carrier therefor are also disclosed.
