Identify the hardware components

The following graphics identify the hardware components and port locations for the control enclosure and expansion enclosure on Storwize® V3700 systems.

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.

Note: Figure 1 and Figure 2 show an enclosure that is equipped with alternating current (AC) power supplies. Some enclosure enclosure models have direct current (DC) power supplies instead (see Reviewing your packing slip for the model numbers). For more information about DC power supply units, see Direct current power supply units.
Note: Figure 1 shows the node canisters in their initial configuration, with no host interface adapter options installed.

Data ports

Figure 2 shows the rear view of a Storwize V3700 control enclosure and identifies the location of the ports.

  •  1  USB ports. Each canister has two USB ports. One port is used during installation.
  •  2  Ethernet ports. Each canister has two 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.
  •  3  Serial-attached SCSI (SAS) ports. 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.

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.

Expansion enclosure components

Figure 4 shows the location of the power supply units and expansion canisters.
  •  1  Expansion canisters
  •  2  Power supply units

Note: Figure 4 shows an enclosure that is equipped with alternating current (AC) power supplies. Some enclosure models have direct current (DC) power supplies instead (see Reviewing your packing slip for the model numbers). For more information about DC power supply units, see Direct current power supply units.
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 always used. Port 2 is used only if this is not the last enclosure in the chain.

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.

Miscellaneous hardware

The USB flash drive (Figure 7) is packaged with the publications and contains the initialization tool for completing the initial system configuration.
