Storage server

A storage server, suitable for installing in a case, the storage server comprising a chassis and at least one slide tray, the at least one slide tray located inside the chassis and being stacked and overlapped with each other, each slide tray being electrically connected to a power supply at a back end of the storage server via a first cable, the at least one slide tray comprising:

• at least one storage module disposed along two opposite sides of the slide tray and extended from a rear end to a front end of the slide tray, the storage module comprising:
• a storage backplane disposed on the slide tray;
• and
• two pairs of storage units back-to-back aligned with each other and electrically connected to the storage backplane, the respective storage unit being individually plugged into or pulled out from the storage backplane;
• at least one thermal dissipation module disposed at a front portion of the slide tray and located at a front end of the storage module;
• an transfer board disposed at a front portion of a channel located between the at least storage module at the two opposite sides of the slide tray, the transfer board being electrically connected to the storage backplane via a second cable and electrically connected to the thermal dissipation module via a third cable;
• a circuit board plugged into or pulled out from the transfer board at a front end of the channel and electrically connected to the transfer board, the circuit board comprising at least one connector, the storage server expanding its storage capacity by interconnecting the at least one connector with each other, and the storage server being connected to an external server via the at least one connector for expanding a storage capacity of the external server;
• and
• a power backplane disposed at a rear portion of the channel and electrically connected to the storage units via a fourth cable.
