8-Lane PCIe Switch in NAS Gateways

Networks with combined network attached storage (NAS) and storage area networks (SAN) are becoming more prevalent. To prevent these systems from becoming single points of failure they need to have high reliability with failover capability. The PEX 8508 is a 5-port, 8-lane PCI Express switch with a host of capabilities that allow dual primary and backup processor boards to offer failover capability. The switch's highly flexible configuration options include two x4-lane ports.
