High Density 2U JBOD with Tool-less Tray Design

  • Lock-in Mini-SAS Module
  • Front Load Screw-less HDD Trays
  • 2OU JBOD with QCT Patented
  • Support up to 28 x 3.5

High Density 28 hot-swappable HDD

The JBR is based on Quanta's patented "hidden-shelf" chassis design to fit 28x 3.5 inch hard disks in a 2 OU space.

Lock-in Mini-SAS module for better cable management

Serviceability is a key objective for the JBR. With its unique hidden-shelf design and lock-in Mini-SAS module design, datacenter operators can swap failed disks without adjusting the cables.

Screw-less tray, easy-to-service

Our engineers have overcome the toughest RVI (Rotational Vibration Interference) challenge to bring datacenter operators the all new screw-less hard disk tray design, making failed drive replacement a less time-consuming task.
