NUMAlink

NUMAlink is a system interconnect developed by Silicon Graphics (SGI) for use in its distributed shared memory ccNUMA computer systems. NUMAlink was originally developed by SGI for their Origin 2000 and Onyx2 systems. At the time of these systems' introduction, it was branded as "CrayLink" during SGI's brief ownership of Cray Research.[1]

Hewlett Packard Enterprise entered an original equipment manufacturer (OEM) arrangement with Silicon Graphics International (SGI) to use Numalink as the foundation in some mission critical servers.[2]

Notes
  1. ^ Bandwidth per port in each direction (each NUMAlink port is a dual simplex channel).
  2. ^ DASH used separate request and reply mesh networks, so this bandwidth number is not directly comparable to NUMAlink.
