XMC storage modules provide dense storage capacity, coupled with the performance of NVMe SSD devices, in flexible XMC Switched Mezzanine Card format. These boards are a convenient way of adding I/O capability to a system via XMC Carriers, or via processor cards with one or more XMC sites. They provide I/O expansion to standard form factors such as OpenVPX, AdvancedTCA and MicroTCA, with air-cooled and conduction-cooled variants being available.
