The following graphics identify hardware components and port locations for the control
enclosures and 2U expansion enclosures of the system.
Control enclosure components
The Storwize® V7000 Gen3 control enclosure contains two node canisters. A label on the control enclosure
identifies each node canister and power supply unit (PSU). As Figure 1 shows, node canister 1 is on top and
node canister 2 is on the bottom. Because the node canisters are inverted, the location of the ports
and the numbering of the ports are oriented differently on each node canister. It is important to
remember this orientation when you are installing adapters and cables. Figure 1. Label showing the orientation of the node canisters and PSUs
For example, Figure 2 shows the top node canister. On this
canister, the numbering of the PCIe slots and ports goes from right to left. PCIe adapter slot 1
contains a 4-port 16 Gbps Fibre Channel adapter. PCIe slot 2 contains a 2-port 25 Gbps iWarp
Ethernet adapter. PCIe slot 3 contains a 4-port 12 Gbps SAS adapter. The onboard Ethernet and USB
ports are also shown.Figure 2. Orientation of ports on node canister 1
Figure 3 shows the bottom node canister. This
node canister has the same type and number of adapters installed. However, on the bottom canister,
the numbering of the PCI slots and ports goes from left to right.Figure 3. Orientation of ports on node canister 2
Data ports
Four 10 Gbps Ethernet ports on each node canister provide system management
connections and iSCSI host connectivity. The onboard 10 Gbps Ethernet ports use RJ-45 connections,
not optical connections. The 10 Gbps ports operate at 1 Gbps when connected to a 1 Gbps switch. A
separate technician port provides access to initialization and service assistant functions. Table 1 describes each port.

Control enclosure support rails
The left and right control enclosure support rails are designed specifically for installation of
a control enclosure.
The ledge on the inside of the rails supports the entire length of a control enclosure.
At the rear end of the control enclosure support rail, the top edge curves over to capture the
top edge of an inserted control enclosure. This prevents the installed control enclosure bouncing
when the rack is subjected to quake or vibration.
The control enclosure support rails adjust to fit racks from 685 mm to 765 mm deep, measured
between the front and rear rack rails.
Figure 4
shows the location of the power supply units and expansion canisters.

Figure 5 shows the LEDs and SAS port locations
from the rear view of an expansion canister.
1 LEDs
2 SAS ports
Each canister has two SAS ports that are numbered 1 on the left and 2 on the right. Port
1 is used to connect to a SAS expansion port on a node canister or port 2 of another expansion
canister.

2U Expansion enclosure support rails
The left and right expansion enclosure support rails (Figure 6) are designed specifically for
installation of an expansion enclosure.
The ledge on the inside of each rail supports the entire length of an expansion enclosure.
The expansion enclosure support rails capture the left and right rear edges of an inserted
expansion enclosure. This prevents the installed control enclosure bouncing when the rack is
subjected to quake or vibration.
The expansion enclosure support rails adjust to fit racks from 595 mm to 755 mm deep, measured
between the front and rear rack rails.
