Structera S
CXL switches

The Structera S series of CXL switches is designed to increase memory bandwidth and capacity in data centers by providing access to disaggregated memory resources outside the server. CXL switches enable memory pooling across the rack, allowing for memory resource allocation across accelerators without replacing existing platforms. Memory pooling using Structera S CXL switches enables higher memory utilization, improved data flow efficiency, higher AI application performance and greater infrastructure design flexibility and scalability. Structera S switch devices are also available for PCIe applications.

• CXL-native switching fabric with full CXL 2.0 compliance
• Configurable 16 ports (x16) or 32 ports (x8)
• Up to 2 TB/s switching capacity
• Support for CXL Type 2 and Type 3 devices
• CXL fabric manager support
• CXL memory pooling and sharing, dynamic capacity allocation
