The MXS824 is Dolphin's fourth generation PCIe switch product and enables users the ability to create a scalable PCIe fabric solution using standard PCIe copper or fiber cables. PCIe solutions running over back planes can now easily be enabled to run over external cables. Larger PCIe configurations can be realized by interconnecting multiple MXS824 switches. By loading the appropriate firmware, the MXS824 supports both transparent and non transparent bridging (NTB) use cases for clustering and I/O expansion applications.
The MXS824 is the high-end switching component in Dolphin's new PCI Express Gen3 product family.. This 24 port 1U cluster switch delivers 32 GT/s of non-blocking bandwidth per port at ultra low latency. Up to 4 ports can be combined into a single x16 / 128 GT/s port if higher bandwidth is required. Each connection is fully compliant with PCI Express Gen1, Gen2 and Gen3 I/O specifications.
Applications that does not need PCIe x16 speed can alternatively use the 8 port x8 PCIe Gen3 IXS600 switch.
PCIe IO Expansion
The MXS824 switch used in combination with the MXH832 or the PXH832 will support standard IO expansion, connecting one server to many PCIe Devices or PCIe Expansion chassis. Additional configurations supporting multiple hosts and switch partitioning, fail-over configurations will be supported in the future. Management and configuration of the PCIe fabric will be done through the Ethernet port.
PCIe Clustering / Networking
For host to host communication, the MXS824 can be combined with Dolphin’s PXH830 or MXH830 Host Adapters. Operating in Non Transparent Bridging mode, Dolphin has solved the strict power on requirements normally associated with PCI Express. Hosts, cables, and the switch can be hot-swapped and power cycled in any order, providing real plug and play as normally expected from networking components.
The MXS824 supports Dolphin’s extensive PCI Express Software libraries to create a powerful and reliable communication solution.
