## Background
BACKGROUND
1. Technical Field
The present invention relates to a server, particularly to a server chassis capable of accessing and rotating storage devices accommodated therein.
2. Related Art
The conventional server system mainly has electronic components such as the motherboard, the storage devices, or the power supply installed in the casing, and the interior space of the casing is usually divided into a plurality of insertion spaces which are provided to accommodate multiple storage devices arranged in an array. The most common storage device includes a hard disk drive or a solid state drive, etc. However, due to the demand of calculation ability and massive data storage, the server needs to accommodate more storage devices in a very limited casing space. Therefore, the size of the server casing also needs to be change correspondingly.
However, since the user needs to change or replace the storage devices in the server, the server casing needs to reserve sufficient space for replacing or accessing the storage devices. Therefore, if the interior of the casing of the server is provided with storage devices arranged side by side, the length of the casing also needs to be elongated, which increases the space occupied by the server system and causes inconvenience to the user.
BRIEF SUMMARY
The present invention provides a server chassis capable of accessing and rotating the storage devices accommodated therein. The rotatable rack can rotate with respect to the casing to obliquely access the storage devices, thereby achieving the goal of increasing the quantity of the storage devices while decreasing the length of the casing.
The server chassis includes a casing, a motherboard, a rotatable rack, a fan module, and an electronic device. The casing includes an accommodating space. The motherboard is disposed in the accommodating space. The rotatable rack is also disposed in the accommodating space and able to rotate with respect to the casing. The rotatable rack has a plurality of insertion spaces for accommodating the storage devices. The fan module is disposed in the accommodating space and electrically connected to the motherboard. The fan module is disposed on one side of the rotatable rack. The electronic device is disposed in the accommodating space and electrically connected to the motherboard. The electronic device is adjacent to the fan module and disposed on one side of the rotatable rack, and a cord passage is provided between the electronic device and the fan module. The storage devices disposed in the rotatable rack are electrically connected to the motherboard via the cord passage.
The present invention also provides another server chassis capable of accessing and rotating the storage devices, and the input/output backplane of the rotatable rack has power supply port. The power supply port and the power supply module are disposed on the same side of the casing, thereby shortening the distance between the power supply port and the power supply module.
Compared to the conventional technique, the server chassis of the present invention includes rotatable racks axially disposed in the casing and rotatable with respect to the casing. By the rotation of the rotatable rack, the storage devices can be obliquely pulled out or inserted into the rotatable rack, thereby shortening the length of the casing, and also minimizing the space occupied by the server system. Through this arrangement, practicality and flexibility for using can be achieved.
