PCI—express slot for coupling plural devices to a host system
View Patent ↗A PCI-Express slot for coupling devices to a host system is provided. The slot includes a PCI-Express connector that can couple at least two devices using at least two independent PCI-Express lanes. Four, eight, twelve, sixteen, and/or thirty PCI-Express lanes are used to couple at least two devices, and/or eight PCI-Express lanes are used to couple at least two devices.
1. A PCI-Express slot for coupling PCI-Express devices to a host system including a processor, the PCI-Express slot comprising:
a PCI-Express connector for receiving a card having at least two independent PCI-Express devices, each independent PCI-Express device using an independent set of PCI-Express lanes;
wherein the PCI-Express slot is located on a motherboard of the host system and the host system processor communicates with the at least at least two independent PCI-Express devices via the two independent sets of PCI-Express lanes without using a bridge.
2. The PCI-Express slot of claim 1 , wherein four PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
3. The PCI-Express slot of claim 1 , wherein eight PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
4. The PCI-Express slot of claim 1 , wherein twelve PCI-Express lanes are used to couple at least two independent PCI-Express devices.
5. The PCI-Express slot of claim 1 , wherein sixteen PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
6. The PCI-Express slot of claim 1 , wherein thirty two PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
7. The PCI-Express slot of claim 1 , where ×2, ×4, ×8, ×12, ×12, ×16 or ×32 PCI-Express lane configurations are used to couple the at least two independent PCI-Express devices.
8. A system for coupling plural PCI-Express devices to a host system including a processor, the system comprising:
a motherboard with a PCI-Express slot having a PCI-Express connector configured to receive a card having at least two independent PCI-Express devices, each independent PCI-Express device using an independent set of PCI-Express lanes;
wherein the host system processor communicates with the at least two independent PCI-Express devices via the two independent sets of PCI-Express lanes without using a bridge.
9. The system of claim 8 , wherein four PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
10. The system of claim 8 , wherein eight PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
11. The system of claim 8 , wherein twelve PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
12. The system of claim 8 , wherein sixteen PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
13. The system of claim 8 , wherein thirty two PCI-Express lanes are used to couple the a least two independent PCI-Express devices.
14. The system of claim 8 , wherein ×2, ×4, ×8, ×12 , ×12, ×16 or ×32 PCI-Express lane configurations are used to couple the at least two independent PCI-Express devices.
15. A PCI-Express connector in PCI-Express slot on a mother board of a host system, the host system including a processor, the connector being configured to receive a card having at least two independent PCI-Express devices to couple the independent PCI-Express devices to the host system, each independent PCI-Express device using an independent set of PCI-Express lanes, wherein the host system processor communicates with the at least two independent PCI-Express devices via the two independent sets of PCI-Express lanes without using a bridge.
16. The PCI-Express connector of claim 15 , wherein four PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
17. The PCI-Express connector of claim 15 , wherein eight PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
18. The PCI-Express connector of claim 15 wherein twelve PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
19. The PCI-Express connector of claim 15 , wherein sixteen PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
20. The PCI-Express connector of claim 1 wherein thirty two PCI-Express lanes are used to couple the at least two independent PCI-Express devices.
21. The PCI-Express connector of claim 15 , wherein ×2, ×4, ×8, ×12, ×12, ×16 or ×32 PCI-Express late configurations are used to couple the at least two independent PCI-Express devices.
