Description

Active-Active Dual Host Dual Controller Architecture

The COTT-JSS202-S24RJ is a 2U24-bay 2.5” drives dual-active JBOD product with two controller modules interconnected via X8 PCI-E 3.0 NT for cache mirroring. The entire system is based on a cable-less, modular design.

 

Versatile I/O Interface 

Each controller support  1*SFF8644 SAS-in and 2*SF8644 SAS-out, 1*RJ45 port for debug and management

 

Energy Saving for Green

The power system equips platinum 1+1 redundant power supply, intelligent fan speed control is based on PID closed-loop control, power capped NM technology, and DC-DC switching power supply with up to 94% power efficiency, which greatly reduces system power consumption
