News editors obtained the following quote from the background information supplied by the inventors: "Hot-swappable devices in a server usually include a hot-swappable power source, a hot-swappable hard drive, a hot-swappable battery, and a hot-swappable fan. The hot-swappable devices are usually installed on a panel or a backplate of the server and can be replaced directly from the panel or backplate. A hot-swappable device usually has a handle to be held and a latch for positioning after the hot-swappable device has been installed. Hot swapping refers to the ability to directly connect or remove components from a computer system without shutting down the computer system. Hot-swap capability is especially important with server-class systems, allowing the system to be expanded for better performance without interrupting services.
"With present configurations, after a hard drive is fastened to a conventional hot-swappable hard drive tray, the hot-swappable hard drive tray can be installed in a host by sliding along slide rails of the host. Typically, the hard drive is fastened to the hard drive tray using screws.
"However, the conventional hard drive tray allows for installation of only one hard drive thereon. When a user pulls out the hard drive tray, the signals and power to the hard drive on the hard drive tray will be interrupted, resulting in a long interruption for the system. The system subsequently needs some time to re-establish data connections. In addition, a server that supports hot-swappable hard drive trays usually has a standard size, and so in an application that requires a lot of hard drives, use of conventional hard drive trays in the server allows for accommodation of only a relatively small number of hard drives. Therefore, if the number of hard drives is increased, the number of servers also needs to be increased. This results not only in increased costs, but a large volume for the whole computer system."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "The disclosure provides a hard drive tray device in which at least two carrying portions are disposed on a base of a tray, and the carrying portions can respectively carry two storage devices, thereby allowing the number of storage devices accommodated in a single server to be increased. The hard drive tray device of the disclosure includes a rail member that is disposed at the inner wall of the housing of the server and is slidably engaged with the tray, so when the rear storage devices (i.e., the storage devices that are deeper in the housing) need to be repaired, a user can assemble/disassemble the rear storage devices in the same way that the front storage devices (i.e., the storage devices that are closer to the periphery of the housing) are assembled/disassembled, namely, by simply pulling the tray out of the housing. In addition, a hollow portion is formed on the base and located between the carrying portions. Therefore, when the server is installed at a high place, the user can easily assemble/disassemble the rear storage devices by passing a hand through the hollow portion from the bottom of the tray after the tray is pulled out of the housing. Moreover, the hard drive tray device of the disclosure includes a cable bracket that is operatively connected to the inner wall of the housing. The cable bracket can slide to be folded relative to the housing together with the tray and be attached by transmission cables used to connect the storage devices to the server. Therefore, when the user pulls out the hard drive tray device, the transmission cables that attach on the cable bracket do not interfere with the movement of the hard drive tray device. Furthermore, because the transmission cables are still connected among the storage devices and the server during the moving of the hard drive tray device, the power and signals provided to the storage devices will not be interrupted.
"According to an embodiment of the disclosure, a hard drive tray device is applied in a server. The server includes a housing. The hard drive tray device includes a rail member and a tray. The rail member is disposed at the inner wall of the housing. The tray is slidably engaged with the rail member so as to slide between an expanded position and a closed position relative to the housing. The tray includes a base for carrying two storage devices. The base has a hollow portion. The storage devices are respectively located at two sides of the hollow portion. When the tray slides to the expanded position, one of the storage devices and at least a part of the hollow portion are located outside the housing.
"In an embodiment of the disclosure, the base includes a first carrying portion and a second carrying portion. The first carrying portion and the second carrying portion are respectively located at two sides of the hollow portion and respectively carry the storage devices. When the tray slides to the closed position, the first carrying portion and the second carrying portion are located in the housing. When the tray slides to the expanded position, the first carrying portion is located outside the housing, and the second carrying portion is located in the housing.
"In an embodiment of the disclosure, when the tray slides to the expanded position, the hollow portion is entirely located outside the housing, and the second carrying portion is aligned with an edge of the housing.
"In an embodiment of the disclosure, the hollow portion has a width between the first carrying portion and the second carrying portion, and the width is greater than the length of any of the storage devices.
"In an embodiment of the disclosure, the hard drive tray device further includes two racks. The racks are respectively disposed on the first carrying portion and the second carrying portion. Each of the storage devices is removably accommodated in the corresponding rack.
"In an embodiment of the disclosure, a removal direction of each of the storage devices relative to the corresponding rack is parallel to a sliding direction of the tray relative to the housing.
"In an embodiment of the disclosure, the hard drive tray device further includes a handle connected to the first carrying portion.
"In an embodiment of the disclosure, the storage devices are electrically connected to the server by using two transmission cables respectively. The hard drive tray device further includes a cable bracket operatively connected to the inner wall of the housing. The cable bracket is expanded or folded together with the sliding of the tray relative to the housing. The transmission cables are attached on the cable bracket.
"In an embodiment of the disclosure, the cable bracket includes a first bracket portion and a second bracket portion. One end of the first bracket portion is pivotally connected to the inner wall of the housing. Two ends of the second bracket portion are pivotally connected to the base and another end of the first bracket portion, respectively.
"In an embodiment of the disclosure, the tray further includes a side plate connected to an edge of the base for slidably engaging the rail member.
"It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the disclosure as claimed.
