Product Data
The MXH915 Gen4 Host Adapter is our entry level PCIe 4.0 solution for connecting servers to external I/O subsystems. Based on Microchip® Gen4.0 PCI Express bridging architecture, the MXH915 adapter enables reliable transparent PCIe cable connections and clock isolation.
Compatibility
The card does not supports the new PCI-SIG CMI (Cable Management Interface ) protocol as defined in the current PCI-SIG External Cable specification 3.0 but uses a proprietary mechanism to transmit reset. Please contact Dolphin for more information on compatibility for PCIe target devices. If you need a transparent card with Host and Target functionality supporting the CMI protocol, please select the MXH932.
Cables
The MXH915 is carefully designed for maximum cable lengths. Fiber optics extends this distance to 100 meters. More info on cable alternatives for the MXH932 card.
Configurations
The MXH915 uses an on-board DIP-Switch to select operational parameters.
eXpressWare Board Management Software
The MXH915 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.
