This application claims the benefit of Taiwan application Serial No. 93210336, filed Jun. 30, 2004, the subject matter of which is incorporated herein by reference.
1. Field of the Invention
The invention relates in general to a blade server system, and more particularly to a blade server system which designates and locks two specific pins of a connector on a server blade for a universal serial bus (USB) special application.
2. Description of the Related Art
Ordinary data/resource sharing is built on the operating systems at two terminals (Windows for example), which are linked via a network, and cannot be achieved if the operating system does not provide active network support (a DOS for example) or before the operating system is loaded. Current blade server system, which receives several server blades at the same time, and thus saves a large amount of storage space. Due to the lack of an optical disc drive or a floppy disc drive inside a blade server, operating difficulties would occur for a server without an operating system.
It is therefore an object of the invention to provide a blade server system. The blade server system has a middle plane board, connected to the advanced server management card (ASMC) via a USB signal line to simulate a remote USB optical disc drive or a remote USB floppy disc drive. When connected to a remote computer via the network, the server blade can even ‘see’ a virtual remote USB optical disc drive or remote USB floppy disc drive, and read or write data, or execute specific programs on the remote computer.
The invention achieves the above-identified object by locking a part of the pins of a connector on a server blade for USB specific application, so that other server blades having different pin definitions, as coupled to the middle plane board via the connector, cannot be correctly coupled to the USB signal lines on the middle plane board through these locked pins, thereby being not applicable to the blade server system of the invention.
It is therefore another object of the invention to provide a blade server system, including a middle plane board and a blade server. The server blade includes a first connector for electrically connecting the middle plane board. The first connector has several pins complying with an EPT 246-31300-15 specification. Among the pins, an H8 pin and an H9 pin are used for a USB special application. The middle plane board includes a second connector having several slots for receiving the pins correspondingly. A first slot and a second slot respectively receive the H8 pin and the H9 pin.
The first slot and the second slot are respectively connected to the ASMC via a first USB signal line and a second USB signal line. By locking the H8 pin and the H9 pin for the USB special application, the blade server system of the invention will not be copied by other manufacturers.
Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiments. The following description is made with reference to the accompanying drawings.
Referring to
Referring to
When the H8 pin 201 and the H9 pin 202 are respectively inserted into the first slot 211 and the second slot 212, the first slot 211 and the second slot 212 are connected to the ASMC 140 via the first USB signal line 221 and the second USB signal line 222 respectively. Therefore, the server management firmware of the ASMC 140 can decode and pack commands and data of the server blade 110 into a network packet, then have the packet transmitted to the remote computer 160 via the network 150. The remote computer 160 actually accesses optical disc drive data or changes to read specific data, startup programs or operating system programs for instance, packs the results and data into a network packet to be transmitted to the ASMC 140, then the data are converted into a USB packet via the ASMC and transmitted to the server blade 110, so that a USB special application required by the server blade 110 is completed.
According to the above-mentioned preferred embodiment, the blade server system of the invention has the following advantage. By locking two pins of a connector on a server blade for the above-mentioned USB special application, other server blades having different pin definitions, as coupled to the middle plane board via the connector, cannot be correctly coupled to the USB signal lines on the middle plane board through these locked pins, thereby being not applicable to the blade server system of the invention.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
