A system including a scalable memory pool. In some embodiments, the system includes: a first memory node, including a first memory; a second memory node, including a second memory; and a memory node switching fabric connected to the first memory node and the second memory node, the memory node switching fabric being configured to provide access, via the first memory node: with a first latency, to the first memory, and with a second latency, greater than the first latency, to the second memory.
