Connections

Ensure that you are familiar with the specific connection types for the system.

Each node requires the following connections:

Each system node requires one Ethernet cable to connect it to an Ethernet switch or hub. The cable must be connected to port 1. For 1 GbE ports, the minimum link speed is 100 Mbps; for 10 GbE ports, the minimum link speed is 1 Gbps. Both Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are supported.
Note: For increased redundancy, an optional second Ethernet connection is supported for each system node. This cable is connected to Ethernet port 2.
To ensure system failover operations, Ethernet port 1 on all nodes must be connected to the same set of subnets. If used, Ethernet port 2 on all nodes must also be connected to the same set of subnets. However, the subnets for Ethernet port 1 do not have to be the same as Ethernet port 2.
Each system node has four Fibre Channel ports, each of which is supplied with an LC-style optical small form-factor pluggable (SFP) transceiver that is a gigabit interface converter (GBIC) for connecting to a Fibre Channel or Fibre Channel over Ethernet (FCoE) switch.
SAN Volume Controller models 2145-DH8 and 2145-SV1 support the 10 Gbps Ethernet adapter, with four FCoE ports.
SAN Volume Controller 2145-SV1 supports the 25 Gbps Ethernet adapters.
Each system node requires connections to the host systems. This connection might be:
- Fibre Channel connections
- iSCSI connections through Ethernet ports
Fibre Channel ports and FCoE ports connect nodes in the system.
