描述 Description

The Switchtec PM8546 PSX PCIe Gen 3 Storage Switch is a programmable, high-reliability PCIe Base Specification 3.1-compliant switch supporting 96 lanes, 48 ports, 24 virtual switch partitions, 48 Non-Transparent Bridges (NTBs), and hot- and surprise-plug controllers for each port. The switch family also features advanced error containment, comprehensive diagnostics and debug capabilities, a wide breadth of I/O interfaces, and anintegrated MIPS processor. PSX switches utilize a system-on-chip architecture that optionally enables customer-differentiated solutions through firmware customization and enhancements.
