Memcached server functionality in a cluster of data processing nodes

摘要

A method is performed by a first server on a chip (SoC) node that is one instance of a plurality of nodes within a cluster of nodes. An operation is performed for determine if a second one of the SoC nodes in the cluster has data stored thereon corresponding to a data identifier in response to receiving a data retrieval request including the data identifier. An operation is performed for determining if a remote memory access channel exists between the SoC node and the second one of the SoC nodes. An operation is performed for access the data from the second one of the SoC nodes using the remote memory access channel after determine that the second one of the SoC nodes has the data stored thereon and that the remote memory access channel exists between the SoC node and the second one of the SoC nodes.

1. A method comprising:
determining, at a first node server, if a second node server has data stored thereon corresponding to a data identifier in response to the second node server receiving a data retrieval request from the first node server including the data identifier; determining, at the first node server, if a remote memory access channel exists between the first node server and the second node server; accessing, at the first node server, the data from the second node server using the remote memory access channel after determining that the second node server has the data stored thereon and that the remote memory access channel exists between the first node server and the second node server; and mapping, at the first node server, a first physical address on the first node server corresponding to the data retrieval request and a second physical address on the second node server.
