Qsan’s storage systems are designed for high 
availability, non-stop services, applications 
demanding high throughput, and flexible 
storage planning with cost effectiveness for 
small and medium businesses.

J220Q 3G SAS-SAS JBOD system is specially designed for high availability applications. 

The  J220Q  is  well  equipped  with  fully  redundant  components  for  all  major  functions, 

including  redundant  JBOD  controllers,  power  supplies,  fan  modules,  and  SAS  JBOD 

expansion ports. Being hot pluggable, all of them provide non-stop services. Distinct from 

others,  J220Q  is  able  to  upgrade  firmware  without  system  down  time. And  in  case  of 

multiple hardware failures as shown below, Qsan’s design of dual paths between Qsan 

RAID systems and JBOD systems will still provide services; while other vendors will not 

be able to provide any service.

Dual controllers

Single controller*

All J220Q systems are equipped with Qsan’s default green features for power saving. In 

most cases, the hard drives consume most power. With the auto disk spin down feature 

and proper configuration (with Qsan Q Series High Availability RAID Systems), the power 

consumption of hard drives can be reduced to a minimum, and users will not even notice 

this feature. J220Q monitors the environment temperature for cooling mechanism and the 

fan  modules  respond  accordingly.  The  power  supply  modules  are  all  80  PLUS  power 

efficient  for  better  power  converting  rate.  In  virtue  of  the  reduction  of  hard  drive  power 

consumption, the advanced cooling mechanism, and the energy-efficient power supplies, 

the unnecessary power cost is decreased greatly.

1. Fully redundant & hot pluggable designs: JBOD 

controllers, power supplies, fan modules, & 
JBOD expansion

2. Online FW upgrade, no system down time 
3. Green storage designs: auto disk spin down, 

advanced cooling mechanism, & 80 PLUS 
energy-efficient power supplies

4. High connection availability: load balancing & 

failover

5. 1 x 3G SAS (miniSAS SFF8088) host wide port 

per controller

6. 1 x 3G SAS (miniSAS SFF8088) JBOD 

expansion wide port per controller

7. SATA II drive backward-compatible

* The specific functions of dual controller are not available in J300Q-C316.
