SAS cable differences between high-density disk enclosures and common disk enclosures in the OceanStor V3 Series

0

Both high-density and common disk enclosures use mini SAS HD cables for connection. Each expansion enclosure of high-density disk enclosures uses two mini SAS HD cables but each common disk enclosure only uses one mini SAS HD cable.

Restrictions on hybrid configuration of high-density disk enclosures and common disk enclosures in the OceanStor V3 Series
There is no restriction on hybrid configuration of high-density disk enclosures and common disk enclosures. However, the performance may be adversely affected because two SAS cables are applied to each high-density disk enclosure while only one SAS cable is applied to each common disk enclosure and the transfer rates are different.

V3 high-density disk enclosure
V3 high-density disk enclosures are described as follows: A high-density disk enclosure adopts a modular design and consists of a system enclosure, disk modules, fan modules, power modules, and expansion modules.

Heat dissipation methods of the OceanStor V3 Series high-density disk enclosures
A special design enables greater heat dissipation. The air volume of fans used for high-density disk enclosures is larger than that of fans used for common disk enclosures. In addition, the air duct system is optimized to dissipate heat.
