The MXH832 Gen3 Host/Target Adapter is our high performance transparent solution for connecting servers to external I/O subsystems. Based on Microsemi® Gen3.1 PCI Express bridging architecture, the MXH832 adapter enables reliable transparent PCIe cable connections and clock isolation.
For high performance application, such as GPU farms, test and measurement equipment, medical equipment, and storage subsystem, the MXH832 delivers flexibility and performance with extremely high data quality. It combines 128 Gb/s performance with the low latency of PCI Express, which is ideal for external I/O Expansion systems.
The MXH832 card has a quad SFF-8644 cable connector and supports MiniSAS-HD cables as well as the new PCIe 3.0 cables. Using the MXH832 as both Host and Target, standard MiniSAS-HD cables enables basic transparent Host and Target operations including propagation of host reset signal to the downstream device.
The card also supports the new PCIe 3.0 cables and the new PCI-SIG CMI (Cable Management Interface ) protocol including WAKE and POWER-ON functionality as defined in the current PCI-SIG External Cable specification 3.0. When the MXH832 is used in conjunction with the new PCI-SIG external PCIe 3.0 cables, it can connected to any compliant downstream device.
The MXH832 is carefully designed for maximum cable lengths. Fiber optics extends this distance to 100 meters. More info on cable alternatives for the MXH832 card.
The MXH832 uses an on-board DIP-Switch to select between Host and Target operations and to set other operational parameters. The adapter cable port can be configured as four x4, two x8 or one x16 PCIe connections.
eXpressWare Board Management Software
The MXH832 Adapter card comes with the optional eXpressWare Board Management software for simplified monitoring and management. The adapter also comes with optional support for SMbus and configuration via a Board Management Controller. For more information on Dolphin board management software visit here.
