Q1. What is a redundant power supply, and what are the advantages of using a redundant power supply above a standard power supply?
A. A redundant power supply unit consists of two power supplies which simultaneously share load during normal operation. If either of the power supplies fail, is switched off, or is physically removed, the other power supply still functioning immediately and automatically assumes the entire electrical load without any loss of power to the peripherals connected to the redundant power supply. A redundant power supply is an excellent option to consider when safeguarding against loss of data caused by a malfunctioning power supply. When one of the power supplies has failed, there is instant and easily noticeable indication of failure with buzzer alarm, blinking LED display, and power defective signal sent to host.
Q2. What types of Mobile Racks, Drive Cartridge Systems, and other storage devices can be installed inside the Storage Rack?
A. The Storage Rack contains 9 standard 5.25" drive bays. Storage devices designed in this form factor can be mounted into any available drive bays. With optional 3.5" to 5.25" mounting brackets (which can be found in the Cables, Brackets, Misc section of the website), storage devices designed in 3.5" form factor can also be installed inside the Storage Rack.
Qx. What is the maximum number of 3.5" SATA drives capable of being installed inside the Storage Rack?
A. The maximum is twenty 3.5" SATA drives. This is achieved by installing three Disk Array (AE5RCS35NSA or AESN5DA35) units into the front of the Storage Rack and one Disk Array on the back of the Storage Rack. Each of the drives will have their own removable drive tray, power switch, and power/drive activity LEDs indicators.
