and model Number of EIA
units required
Notes
File module 2073-720 2 Each of the two file modules is 2 EIA units; each file
module has eight 1 Gbps Ethernet ports, two 10 Gbps
Ethernet ports, and two 8 Gbps fibre channel ports
Planning network cable connections
The cable-connection tables provide a method of recording the locations of current
and planned cable connections for each control enclosure and file module in the
system.
Use these tables to record the locations of cable connections in your Storwize
V7000 Unified system.
Tip: Figures contained in the Installation topics: “Before you begin adding file
models” and “Performing the hardware installation”, illustrate the proper
connections between the file module and the storage enclosure.
Ethernet port 1 on each node canister is used by the active management node on a
file module to access the Storwize V7000 command-line interface (CLI), to monitor
and configure the storage. It is also for accessing the service assistant GUI for the
node canister, and iSCSI host communications. Port 2 can be used for the Storwize
V7000 CLI, and iSCSI host attachment.
Each node canister in a control enclosure connects over an Ethernet cable from
Ethernet port 1 of the canister to an enabled port on your Ethernet switch or
router. Optionally, you can attach an Ethernet cable from Ethernet port 2 on the
canister to your Ethernet network. After the initial configuration of the Storwize
V7000 Unified system, this can be configured as a redundant connection for the file
module to access the Storwize V7000 CLI; refer to the Installation topic: “Next
steps”, for more information.
Control enclosure models 2076-312 and 2076-324 have two 10 Gbps Ethernet ports
per node canister, numbered ports 3 and 4. The 10 Gbps ports can only be used for
iSCSI or Fibre Channel over Ethernet host attachment, and cannot be used for
management or configuration.
File module model 2073-720 has two 10 Gbps Ethernet ports, labelled ports 5 and
6. The 10 Gbps ports of a file module can be used for public file access. It is also
possible to move management communications over to these ports after the initial
configuration of the system.
Note: Ethernet cables are not supplied as part of your order. Ensure that your
cables meet the minimum standards for the Ethernet port type that you are using.
Table 8 provides a list of Ethernet cable standards.
