Product Data
The MXH572 PCIe 5.0 Host/Target Adapter is our high performance transparent solution for connecting servers to external I/O subsystems. Based on Microchip® 5.0 PCI Express bridging architecture, the MXH572 adapter enables reliable transparent PCIe cable connections and clock isolation. The MXH572 is designed to the PCI-SIG CopprLink 1.0 specification.
For high performance application, such as GPU farms, test and measurement equipment, medical equipment, and storage subsystem, the MXH572 delivers flexibility and performance with extremely high data quality. It combines 512 Gb/s performance with the low latency of PCI Express, which is ideal for external I/O Expansion systems.
Cables
The MXH572 card has one CDFP / CopprLink 1.0 x16 cable connector and is optimized to support long copper and fiber optic cables. More information on cables for the MXH572.
Configurations
The MXH572 uses an on-board DIP-Switch to select between Host and Target operations and to set other operational parameters.
eXpressWare Board Management Software
The MXH572 Adapter card comes with the optional eXpressWare Board Management software for simplified monitoring and management. For more information on Dolphin board management software visit here.
PCI Express NTB
The MXH572 card is a transparent product only. To utilize the Dolphin's PCIe NTB eXpressWare clustering software, you need to purchase the MXH570 PCIe 5.0 NTB adapter card.
