This required 10GbE network connects the SPARC T5-8 servers to your existing client network and is used for client access to the servers. 10GbE NICs installed in the PCIe slots are used for connection to this network. The number of 10GbE NICs and the PCIe slots that they are installed in varies depending on the type of configuration that is set up on the SPARC T5-8 server.
In each case, IPMP grouping provides redundancy to the 10GbE client access network, where two physical ports are part of one IPMP group and a single data address accesses these two physical ports. For the situations where the two physical ports are on separate dual-port 10GbE NICs, that data address allows traffic to continue flowing to the ports in the IPMP group, even if one of the two 10GbE NICs fail.
Large Domain: All four PCI root complex pairs, and therefore four 10GbE NICs, are associated with the logical domain on the server in this configuration. However, only two of the four 10GbE NICs are used with this domain. One port is used on each dual-ported 10GbE NIC. The two ports on the two separate 10GbE NICs are part of one IPMP group. One port from the dual-ported 10GbE NICs is connected to the 10GbE network in this case, with the remaining unused ports and 10GbE NICs unconnected.
The following 10GbE NICs and ports are used for connection to the client access network for this configuration:
PCIe slot 1, port 0 (active)
PCIe slot 14, port 1 (standby)
A single data address accesses these two physical ports. That data address allows traffic to continue flowing to the ports in the IPMP group, even if one of the two 10GbE NICs fail.
Medium Domains: Two PCI root complex pairs, and therefore two 10GbE NICs, are associated with the Medium Domain on the SPARC T5-8 server in the Half Rack. One port is used on each dual-ported 10GbE NIC. The two ports on the two separate 10GbE NICs are part of one IPMP group.
The following 10GbE NICs and ports are used for connection to the client access network for this configuration:
First Medium Domain:
- PCIe slot 1, port 0 (active)
- PCIe slot 9, port 1 (standby)
Second Medium Domain, if applicable:
- PCIe slot 6, port 0 (active)
- PCIe slot 14, port 1 (standby)
A single data address accesses these two physical ports. That data address allows traffic to continue flowing to the ports in the IPMP group, even if one of the two 10GbE NICs fail.
Small Domains: One PCI root complex pair, and therefore one 10GbE NIC, is associated with the Small Domain on the SPARC T5-8 server in the Half Rack. Both ports are used on each dual-ported 10GbE NIC, and both ports on each 10GbE NIC are part of one IPMP group. Both ports from each dual-ported 10GbE NIC are connected to the 10GbE network for the Small Domains.
The following 10GbE NICs and ports are used for connection to the client access network for the Small Domains, depending on the CPU that the Small Domain is associated with:
CPU0:
- PCIe slot 1, port 0 (active)
- PCIe slot 1, port 1 (standby)
CPU1:
- PCIe slot 9, port 0 (active)
- PCIe slot 9, port 1 (standby)
CPU6:
- PCIe slot 6, port 0 (active)
- PCIe slot 6, port 1 (standby)
CPU7:
- PCIe slot 14, port 0 (active)
- PCIe slot 14, port 1 (standby)
See Half Rack Domain Configurations for more information on which CPU would be associated with certain Small Domains.
A single data address accesses these two physical ports. That data address allows traffic to continue flowing to the ports in the IPMP group, even if the connection to one of the two ports on the 10GbE NIC fails.
