RELIABILITY, AVAILABILITY, AND SERVICEABILITY IN MULTI-NODE SYSTEMS WITH DISAGGREGATED MEMORY

摘要

A shared memory controller receives a memory access request from a computing node, the request corresponding to a particular line of pooled memory. An error corresponding to the request is identified and the request is forwarded to a second shared memory controller in response to the error. A response is received to the request from the second shared memory controller. The response can be forwarded to the computing node by the shared memory controller.

主权项

1. An apparatus comprising:
a first shared memory controller to control access to a portion of a memory pool, wherein the first shared memory controller comprises:
a first interface to receive a memory access request from a computing node, wherein the request corresponds to a particular line of pooled memory;error detection logic to identify an error corresponding to the request;a second interface to:
send the request to a second shared memory controller in response to the error;receive a response to the request from the second shared memory controller, wherein the first interface is further to forward the response to the computing node.
