    摘要: In one embodiment, the present invention includes canisters to control storage of data in a storage system including a plurality of disks. Each of multiple canisters may have a processor configured for uniprocessor mode and having an internal node identifier to identify the processor and an external node identifier to identify another processor with which it is to mirror cached data. The mirroring of cached data may be performed by communication of non-coherent transactions via the PtP interconnect, wherein the PtP interconnect is according to a cache coherent protocol. Other embodiments are described and claimed.
