Identify the hardware components

Before you install your system, review and identify the hardware components and port locations for the control enclosure and expansion enclosure on the system.

Control enclosure components

Figure 1 shows the rear view of a control enclosure and identifies the location of the power supply units and node canisters.

  •  1  Node canisters
  •  2  Power supply units

Data ports

Figure 2 shows the rear view of a Storwize® V7000 control enclosure and identifies the location of the ports.

  •  1  USB ports. Each canister has two USB ports.
  •  2  Ethernet ports. Each canister has four 1 Gbps Ethernet ports.
    Port 1
    Must be connected for system management. Can optionally be used for iSCSI host connectivity.
    Port 2
    Optional. Can be used for iSCSI host connectivity or to provide an alternative (redundant) management address.
    Port 3
    Optional. Can be used for iSCSI host connectivity.
    Port T
    Technician port. Can be connected directly to a computer for service access and system initialization.
  •  3  Serial-attached SCSI (SAS) ports. Each canister has two SAS ports for connecting to optional expansion enclosures.

Control enclosure support rails

The left and right control enclosure support rails (Figure 3) 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.

2U Expansion enclosure components

Figure 4 shows the location of the power supply units and expansion canisters.

  •  1  Expansion canisters
  •  2  Power supply units
Figure 5 shows the LEDs and SAS port locations from the rear view of an expansion canister. 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.
  •  1  LEDs
  •  2  SAS expansion ports

  •  1  LEDs
  •  2  SAS expansion ports

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.
