Connections
Ensure that you are familiar with the specific connection types for the Storwize® V3700 system.
Each Storwize V3700 system requires the following connections:
- Each Storwize V3700
control enclosure requires two Ethernet cables to connect it to an Ethernet switch or hub. One cable
connects to port 1 of the left node canister, and the other cable connects to port 1 of the right
node canister. A 10/100/1000 Mb Ethernet connection is required for each
cable.
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 Storwize V3700 node canister.
- To ensure system failover operations, Ethernet port 1 on each node canister must be connected to the same set of subnets. If used, Ethernet port 2 on each node canister 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 canister has four SAS ports. Ports 1 to 3 are optionally used for connecting to host systems. Port 4 is optionally used for connecting to expansion enclosures.
Short-wave SFP transceivers are preinstalled in the control enclosure Fibre Channel ports and any 10 Gbps Ethernet ports. You can order long-wave SFP transceivers to replace the short-wave transceivers in the Fibre Channel ports only. 10 Gbps Ethernet ports for FCoE and iSCSI do not use long-wave transceivers.
