Component Description

Component Description

This section provides the detailed illustration and description for each component.

System Subrack

The system subrack houses a midplane to provide reliable connections for interface modules and to distribute power and signals to inner modules.

Appearance

Figure 4-108 shows the appearance of a system subrack.

Expansion Module

Each expansion module provides two PRI HD expansion ports and two EXP HD expansion ports. Expansion modules enable a high-density disk enclosure to communicate with a controller enclosure or another high-density disk enclosure.

Appearance

No.

Indicator Status and Description

1

Power indicator of the expansion module

  • Steady green: The expansion module is working correctly.
  • Off: The expansion module is powered off.

2

Alarm indicator of the expansion module

  • Steady red: An alarm about the expansion module is generated.
  • Off: The expansion module is powered off or working correctly.

5

Mini SAS HD expansion port indicator

  • Steady blue: The link to the expansion port is normal, and the data transfer rate is 4 x 6 Gbit/s.
  • Steady green: The link to the expansion port is normal, and the data transfer rate is 4 x 3 Gbit/s.
  • Steady red: The port is faulty.
  • Off: The link to the expansion port is down.

Disk Module

Disk modules provide storage capacity for a storage system. Service data, system data, and cache data are all saved on disk modules. If a disk enclosure is paired with a 3 U controller enclosure or a 6 U controller enclosure (both enclosure in the form factor of disk and controller separation), the first four disk modules of a controller enclosure are coffer disks. For the four disk modules, each spares 5 GB of space to form RAID 1 to store a storage system's configuration data and improve reliability.

Appearance
