MXS924 PCIe 4.0 Switch
PCI Express 4.0 Switch
Dolphin’s MXS924 High Speed PCI Express switch delivers a powerful and flexible PCI Express external solution. This PCI Express 4.0 switch supports standard I/O expansion and high throughput PCI Express clustering. It is fully supported by Dolphins eXpressWare software suite.
- 24 PCI Express 4.0 x4 ports
- 16 GT/S per lane
- 64 GT/s per port
- NTB or Transparent use
- SFF-8644 Connectors
- PCIe 4.0 SFF-8644 cables
- Hot Plug cabling support
- 19 Inch 1U rack mountable
- Redundant Fans
- Port status LEDs
- Ethernet based management and monitoring
- Microsemi Gen 4.0 PFX chipset
The MXS924 is Dolphin's fourth generation PCIe switch product and enables users the ability to create a scalable PCIe fabric solution using standard PCIe 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 MXS924 switches. By loading the appropriate firmware, the MXS924 supports both transparent and non transparent bridging (NTB) use cases for clustering and I/O expansion applications.
The MXS924 is the high-end switching component in Dolphin's new PCI Express 4.0 product family. This 24 port 1U cluster switch delivers 64 GT/s of non-blocking bandwidth per port at ultra low latency. Up to 4 ports can be combined into a single x16 / 256 GT/s port if higher bandwidth is required. Each connection is fully compliant with PCI Express 1.0, 2.0, 3.0 and 4.0 I/O specifications. The MXS924 is based on the latest Microsemi Switchtec PCIe Gen 4 PFX fanout switch technology.
Applications that does not need PCIe 4.0 x16 speed can alternatively use the 24 port PCIe x16 Gen 3.0 MXS824 switch.
PCIe IO Expansion
The MXS924 switch used in combination with the MXH932 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 MXS924 can be combined with Dolphin’s MXH930 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 MXS924 supports Dolphin’s extensive PCI Express Software libraries to create a powerful and reliable communication solution for applications that benefit from an ultra-low latency, high performance cluster interconnect. Dolphin’s PCI Express Software enables standard and embedded Linux, Windows, RTX and VxWorks network applications to benefit from PCI Express performance without modification. This comprehensive solution is ideal for real-time, technical and high performance computing, cloud computing, and enterprise business applications.
Composable Hardware Infrastructures
The MXS924 can be used to develop composable hardware infrastructures. In this environment, it functions as a top of rack switch which connects both I/O and processing.
The MXS924 supports large reflective memory configurations and multiple multicast groups. Customers using older reflective memory solutions from Dolphin will have en easy migration to the new platform.
Cables and ports
The MXS924 switch has six quad SFF-8644 cable connectors and supports MiniSAS-HD cables as well as the new PCIe 4.0 cables. Each quad port can be used as four independent x4 links, two independent x8 links or one x16 link (in total up to 24 x4 links).
The MXS924 comes with a built in management processor. The processor enables Ethernet based firmware upgrade, switch re-configuration and monitoring. All configuration data is stored in non volatile memory so the processor is not required to bring up a configured product.
