Abstract

A server system includes at least one server, a signal processing unit that enables to operate said at least one server with a set of console, and a chassis having slots and a circuit board, said at least one server or the signal processing unit being attachable and detachable to any of the slots, the circuit board having interconnection lines connecting the slots. Said at least one server and the signal processing unit being connected via an interface that allows plug and play connectivity. Thus, it is possible to construct the server system without external cables. In addition, when a server is newly added to or removed from the system or, it is no longer necessary to power of the other servers. This makes it possible to facilitate system construction and management.

Claims

1. A server system comprising:

at least one server;

a signal processing unit that enables to operate said at least one server with a set of console; and

a chassis having slots and a circuit board, said at least one server or the signal processing unit being attachable and detachable to any of the slots, the circuit board having interconnection lines connecting the slots,

said at least one server and the signal processing unit being connected via an interface that allows plug and play connectivity.

2. A signal processing unit comprising:

a first circuit having an interface that allows plug and play connectivity; and

a second circuit connectable to a server system via the first circuit, the server system having slots that are provided to a chassis and are connected together via interconnection lines, a server being any of the slots.

3. The signal processing unit as claimed in claim 2, wherein the signal processing unit is attachable to any one of the slots of the server system.

4. The signal processing unit as claimed in claim 2, comprising a control circuit that passes only video signals applied from any one of servers inserted into the slots.

5. The signal processing unit as claimed in claim 2, comprising a network adapter that sends and receives packets to and from a client terminal via a network,

the servers inserted into the slots being operated with the set of console provided in the client terminal.

6. A server comprising:

a connector that allows the server to be inserted into any of slots that are provided to a chassis of a server system and are mutually connected via interconnection lines; and

an interface circuit connected to a signal processing unit that is inserted into one of the slots and has an interface that allows the server to be connected to the signal processing unit with plug and play connectivity.

7. The server as claimed in claim 6, further comprising a microcomputer that controls the interface.

8. The server as claimed in claim 6, further comprising a switch that enables or disables an output of video signals.

9. A chassis comprising:

a circuit board having slots into which servers can be inserted; and

interconnection lines that are provided to the circuit board and connects the slots,

the servers being connected, via the interconnection lines, to a signal processing unit having an interface that enables to operate the servers with a single set of console.

10. The chassis as claimed in claim 9, wherein the slots can accommodate the signal processing unit.

11. The chassis as claimed in claim 9, further comprising an external terminal that connects the signal processing unit to the interconnection lines.

12. The chassis as claimed in claim 9, further comprising a microcomputer that controls the interface that has the plug and play connectivity.

13. The chassis as claimed in claim 9, further comprising switches that are provided to slots and enable or disable video signals applied from the servers.

14. The chassis as claimed in claim 9, wherein the circuit board includes a control circuit that passes only a video signal applied from any one of the servers.
