12 QXS Site Planning Guide
QXS-312/324 RAID and Expansion Physical Requirements
The floor space at the installation site must be strong enough to support the combined weight of the
rack, RAID chassis, expansion chassis, and any additional equipment. The site also requires sufficient
space for installation, operation, and servicing of the chassis, together with sufficient ventilation to
allow a free flow of air to all chassis.
Composition
The RAID chassis and expansion chassis is comprised of sheet steel that is bonded together using
rivets, welding, and other forced contact methods. The metal surfaces are free from non-conductive
coatings and paint.
Chassis Designators
The RAID and expansion chassis designators are as follows:
•
2U12 chassis (LFF):
• “2U12” denotes the 3.5” QXS-312 chassis (with controller or expansion modules)
• The 2U12 chassis is equipped with a drive in each drive slot
•
2U24 chassis (SFF):
• “2U24” denotes the 2.5” QXS-324 chassis (with controller or expansion modules)
• The 2U24 chassis is equipped with a drive in each drive slot
•
Two controller modules or two expansion modules per chassis
•
Two power supplies per chassis
