Configuration examples
The MXS824 switch can be used as a standalone PCI Express switch, or several switches can be cascaded to build larger
PCIe expansion systems or PCIe fabrics. It can be combined with compliant PCIe cards available from Dolphin or compliant
customer designs. Some examples can be found below. Please consult the chapter Configuring the MXS824 switch on page
16 for more details.
Please note that the Dolphin eXpressWare currently doesn’t support mixing MXH830 and PXH8x0 in a
single cluster.
6 node PCIe x16 Gen3 NTB Cluster
Each node has a Dolphin Express MXH830, PXH830 or PXH820
adapter. Up to six systems can be connected to the Dolphin
MXS824 switch using the default firmware configuration. All nodes
connect directly to the switch using up to 4 x4 MiniSAS-HD or PCIe
3.0 cables (x16 link). This is the switch default configuration.
12 node PCIe x8 Gen3 NTB Cluster
Each node has a Dolphin Express MXH830, PXH830 or PXH820
adapter. Up to twelve systems can be connected to the Dolphin
MXS824 switch. All nodes connect directly to the switch using up to
2 x4 MiniSAS-HD or PCIe 3.0 cables (x8 link).
24 node PCIe xx Gen3 NTB Cluster
Each node has a Dolphin Express MXH830, PXH830 or PXH820 adapter. Up to twenty-four systems can be connected to
the Dolphin MXS824 switch. All nodes connect directly to the switch using a single x4 MiniSAS-HD or PCIe 3.0 cables (x4
link).
