Expansion Plan

Expansion Plan

Work out a proper expansion plan before installing devices. Then, follow the plan to improve installation efficiency.

Expansion Plan (Applicable to 5000 and 6000 Series)

Before connecting disk enclosures to a controller enclosure, carefully read the following rules:

  • SAS expansion cables must be naturally bent, and a minimum of 97 mm clearance must be reserved in front of each enclosure for winding cables.
  • Connect a controller enclosure to a high-density disk enclosure using mini SAS HD electrical cables. The cables must be naturally bent, and a minimum of 97 mm clearance must be reserved in front of each enclosure for winding cables.
  • Common and high-density disk enclosures cannot be connected to one expansion loop.
  • If a storage system is configured with two or more disk enclosures, you are advised to form multiple expansion loops based on the number of expansion ports on the controller enclosure, and ensure that the disk enclosures are evenly distributed to each loop.
  • (Applicable to 5110 V5, 5300 V5, 5500 V5, 5600 V5, and 5800 V5) Every pair of SAS ports can be connected to a maximum of eight SAS disk enclosures. The recommended number of the connected SAS disk enclosures should not exceed two.
  • (Applicable to 6800 V5) Every pair of SAS ports can be connected to a maximum of four standard SAS disk enclosures.
  • (Applicable to 5300 V5) Every two pairs of SAS ports (a pair consists of two adjacent ports on the same interface module) can be connected to a maximum of seven high-density disk enclosures. It is recommended that the number of high-density disk enclosures connected to two pairs of SAS ports should not exceed two.
  • (Applicable to 5500 V5, 5600 V5, and 5800 V5) Every two pairs of SAS ports (a pair consists of two adjacent ports on the same interface module) can be connected to a maximum of eight high-density disk enclosures. It is recommended that the number of high-density disk enclosures connected to two pairs of SAS ports should not exceed two.
  • (Applicable to 6800 V5) Every pair of SAS ports can be connected to a maximum of four high-density disk enclosures (in single-uplink networking only). The recommended number of the connected high-density disk enclosures should not exceed two.
  • 5110 V5 does not support the high-density disk enclosures.

Expansion Plan (Applicable to 5000F and 6000F Series)

Before connecting disk enclosures to a controller enclosure, carefully read the following rules:

  • SAS expansion cables must be naturally bent, and a minimum of 97 mm clearance must be reserved in front of each enclosure for winding cables.
  • If a storage system is configured with two or more disk enclosures, you are advised to form multiple expansion loops based on the number of expansion ports on the controller enclosure, and ensure that the disk enclosures are evenly distributed to each loop.
  • SAS expansion modules must be installed in slots A0 and B0 of a 3 U controller enclosure and slots L0 (IOM0 for two controllers and IOM0 and IOM1 for four controllers) and R0 (IOM0 for two controllers and IOM0 and IOM1 for four controllers) of a 6 U controller enclosure.
  • A pair of SAS ports can be connected to a maximum of four disk enclosures and one disk enclosure is recommended.
  • V5 F series only support the 2 U SAS disk enclosure.

Layout Plan

Plan the device layout before installing the devices. A proper layout ensures normal running of the storage devices. The devices in the storage system must comply with the following layout principles:

  1. It is recommended that you reserve a 1 U (44.45 mm, 1.75 inches) space between two devices, if possible. Alternatively, you can set five disk enclosures as a group. In a cabinet, at least 1 U space should be reserved between disk enclosure groups for convenient management and less shock transfer.
  2. The layout plan meets the requirement of the power supply and cooling system of the equipment room (depending on the cooling effect of the air conditioner). It is recommended that you place 10 disk enclosures in a single cabinet.
  3. The distance between two adjacent cabinets should be at least 120 cm (47.2 inches). The distance between a cabinet and the wall should be at least 100 cm (39.4 inches).
  4. The bearable weight of the guide rails of a cabinet should be greater than 50 kg, and the bearable weight of the guide rails of a 6 U controller enclosure should be greater than 95 kg.
  5. It is recommended that you use 5 m of SAS cables to connect different cabinets.
  6. It is recommended that the controller enclosure be installed in the middle of the cabinet (from 19 U to 24 U). 2 U space should be reserved above and beneath the controller enclosure to allow for later installation of a side-hanging fiber reel and a cable tray, respectively.
