The Addonics RAID Rack is a family of 1U and 4U Rackmount chassis with removable drive systems for easily adding and removing hard drives. Comes bundled with all the necessary connecting cables for attaching to your system, these RAID Racks are designed to accommodate from four 3.5" SATA hard drive in a 1U Rack to as many as twenty 3.5" SATA hard drives in a 4U Rack. It is the ideal storage solution for video storage, storage farm or any applications that require a high capacity, reliable storage system.
You can start your RAID Rack with as little as one hard drive and expand by adding more hard drives as your storage requirement grows. Depending on the model, the hard drives can be connected to the system with eSATA, USB 3.0 , mini SAS or Firewire cables. The 1U RAID Rack offers choice of models with Port Multipliers or with simple direct drive connection to system via eSATA or mini SAS cables. For the 4U RAID Rack, there is also choice of models with hot swappable redundant power supply for mission critical applications.
The R1MSAS is a 1U RAID Rack that accomodates as many as four 3.5" SATA hard drives (or 2.5" SATA hard drives using Addonics Snap-In 25 adatper), which are connected to a mini SAS bridge mounted on the back of the unit. All four drives are connected to a system equipped with a mini SAS connector (SFF-8088) via a single mini SAS cable. The integrated Snap-In bay provides the convenience in adding or removing drives directly like tape cartridges from each bay without any special tool.
