Overview

Overview

A controller enclosure employs a modular design and consists of a system subrack, controllers, BBUs, power modules, and interface modules.

NOTE:
  • After opening the controller panel latch, you will see that each controller contains three fan modules.
  • The information plate records device information.
  • Controllers A, B, C, and D are placed from top to bottom and from left to right.

Rear View

Figure 4-57 shows the rear view of a controller enclosure.

Do not connect the management network port and maintenance network port to the same switch.

GE electrical port

The GE electrical port is used to connect to the GE electrical port of the application server.

11

10 Gbit/s FCoE port

The 10 Gbit/s FCoE port is used to connect to the 10 Gbit/s FCoE port of the application server.

12

16 Gbit/s Fibre Channel port

The 16 Gbit/s Fibre Channel port is used to connect to the 16 Gbit/s Fibre Channel port of the application server.

13

8 Gbit/s Fibre Channel port

The 8 Gbit/s Fibre Channel port is used to connect to the 8 Gbit/s Fibre Channel port of the application server.

14

Mini SAS HD expansion port

The mini SAS HD expansion port is used to connect to the disk enclosure.

The slots for interface modules of a 6 U controller enclosure are L0, L1, L2, L3, L4, L5, R5, R4, R3, R2, R1, and R0 from left to right. From the top to bottom, the slots are IOM0 and IOM1.
  • R5IOM0 and R0IOM0 are slots for interface modules of controller A.
  • L0IOM0 and L5IOM0 are slots for interface modules of controller B.
  • R5IOM1 and R0IOM1 are slots for interface modules of controller C.
  • L0IOM1 and L5IOM1 are slots for interface modules of controller D.
NOTE:
A controller enclosure provides the following interface modules. You can configure them based on service needs.
  • Slots L0IOM0, R0IOM0, L0IOM1 and R0IOM1 are slots for back-end interface modules and only support 12 Gbit/s SAS expansion modules.
  • Slots L4IOM0, L5IOM0, R4IOM0, R5IOM0, L4IOM1, L5IOM1, R4IOM1 and R5IOM1 are slots for front-end interface modules and do not support 12 Gbit/s SAS expansion modules.
  • When the storage system requires IP Scale-out, SmartIO interface modules must be installed in L3IOM0, R3IOM0, L3IOM1 and R3IOM1 slots for the IP Scale-out.
  • Insert interface modules of the same type into a slot of controller A and the corresponding slot of controller B. Insert interface modules of the same type into a slot of controller C and the corresponding slot of controller D.

    For example, if you insert a 10 Gbit/s TOE interface module into slot R2IOM0 of controller A, you must insert a 10 Gbit/s TOE interface module into slot L2IOM0 on controller B.

  • Management module (mandatory): used for management and maintenance
  • 12 Gbit/s SAS expansion module (mandatory): used for connecting disk enclosures
  • Interface modules (optional but at least one type required): used for connecting application servers
  • Management network ports 1 and 2 have not been enabled, and will be enabled in multi-controller interconnection scenarios.
  • When the maintenance network port is used for management and maintenance, the maintenance network port can only be used by Huawei technical support for emergency maintenance and cannot be connected to the same network with the management network port. Otherwise, a network loopback may occur, causing a network storm. The initial value for the IP address of the maintenance network port is 172.31.128.101 or 172.31.128.102. The default subnet mask is 255.255.0.0. You are advised to only connect the management network port to the network.
