Network cable worksheets
Use the cable-connection tables to record the location and type of cable connections for each control enclosure in the system. The
configuration of the networking adapters differs between FlashSystem 7200 and Storwize V7000 Gen3 control encosures.
Ethernet cable standards
The control enclosure supports Ethernet connections by using onboard ports and ports on networking adapters. The following table
summarizes the Ethernet cable standards for each connection.
Ethernet Port Type
Cable Type
Minimum Standard
Connector
1 Gbps Ethernet technician port
TP
Cat 5e
RJ45
10 Gbps onboard Ethernet ports
TP
Cat 6 (up to 55 m), Cat 6a or Cat 7 (up to 100 m) at 10
Gbps, or Cat 5e at 1 Gbps
RJ45
25 Gbps Ethernet host interface adapter (must be ordered)
Optical
OM3 (up to 70 m) OM4 (up to 100 m)

Onboard Ethernet ports
On the control enclosure, Ethernet port 1 of each node canister is connected to an enabled port on your Ethernet switch or router. Ethernet
port 1 is used for accessing the management GUI, for accessing the service assistant GUI for the node canister, and for iSCSI host
attachment. You can also attach an Ethernet cable from Ethernet port 2 on the node to canister your Ethernet network. Port 2 can be used
for the management GUI and for iSCSI host attachment. Ethernet ports 3 and 4 are for iSCSI attachment only.
The ports on the upper node canister (canister 1) are
numbered from right to left.
The ports on the lower node canister (canister 2) are
numbered from left to right.
Use the following table to record the properties of the onboard Ethernet ports on each node canister of the control enclosure. The
configuration of the onboard Ethernet ports for FlashSystem 7200 and Storwize V7000 Gen3 systems are the same.

FlashSystem 7200 Ethernet networking adapters
Each node canister supports 2-port 25 Gbps internet Wide-area RDMA Protocol (iWARP) or RDMA over Converged Ethernet (RoCE) Ethernet
adapters. Install the adapters according to the following guidelines.
• iWARP and RoCE Ethernet adapters cannot be mixed within a node canister.
• Fibre Channel adapters are installed before Ethernet adapters, beginning with slot 1, then slot 2, and slot 3.
• Ethernet adapters are installed beginning with the first available slot.
