Interleaved card/riser connection assembly for compact card integration
An apparatus is described. The apparatus includes a first riser card connected to a first card. The apparatus also includes a second riser card connected to a second card, wherein, the first card's connection to the first riser card and the second card's connection to the second riser card pass through a vertical plane runs parallel to respective surfaces of the first and second riser cards.
1. An apparatus, comprising:
a motherboard comprising:
a) a first riser card connector to connect to a first riser card;
b) a second riser card connector to connect to a second riser card;
b) a first set of signal wires coupled to the first riser card connector, the first set of signal wires to transport signals to and/or from a first card;
c) a second set of signal wires coupled to the second riser card connector, the second set of signal wires to transport signals to and/or from a second card, the first and second riser card connectors positioned so that when the first card is connected to the first riser card and the second card is connected to the second riser card, the first card's connection to the first riser card and the second card's connection to the second riser card pass through a vertical plane that extends from the motherboard's surface, wherein, the first card's connection to the first riser card fits through an opening in the second riser card and the second card's connection to the second riser card fits through an opening in the first riser card.
2. The apparatus of claim 1 wherein the first and second riser card connectors run parallel to one another on the motherboard.
3. The apparatus of claim 2 wherein the first card is connected to the first riser card and the second card is connected to the second riser card.
4. The apparatus of claim 1 wherein the first card is connected to the first riser card and the second card is connected to the second riser card.
5. The apparatus of claim 1 wherein the first card's connector to the first riser card and the second card's connector to the second riser card face one another when the first card is connected to the first riser card and the second card is connected to the second riser card.
6. The apparatus of claim 1 wherein the motherboard is a 19″ rack mountable component motherboard that can receive four cards along an axis that runs across the 19″ opening of a 19″ rack.
7. The apparatus of claim 6 wherein the 19″ rack mountable component is a server computer.
8. The apparatus of claim 1 wherein at least one of the first set of signal wires and the second set of signal wires implement a PCIe interface.
9. An apparatus, comprising:
a) a first riser card connected to a first card;
b) a second riser card connected to a second card, wherein, the first card's connection to the first riser card and the second card's connection to the second riser card pass through a vertical plane that runs parallel to respective surfaces of the first and second riser cards, wherein:
i) the first riser card has a first opening;
ii) the second riser card has a second opening;
iii) the first card is connected to the first riser card through the second opening;
iv) the second card is connected to the second riser card through the first opening.
10. The apparatus of claim 9 further comprising:
a third card connected to the first riser card through another opening in the second riser card;
a fourth card connected to the second riser card through another opening in the first riser card.
11. The apparatus of claim 10 wherein the first and third cards are stacked and the second and fourth cards are stacked.
12. The apparatus of claim 9 wherein the first and second riser cards and the first and second cards are components of a rack mountable component.
13. The apparatus of claim 12 wherein the rack mountable component is a 19″ rack mountable component.
14. The apparatus of claim 12 wherein the rack mountable component is a computing system or a component of a computing system.
15. The apparatus of claim 12 wherein the rack mountable component is a networking system.
16. The apparatus of claim 9 wherein the first and/or second cards are any of:
a networking adaptor card;
a co-processor card;
a memory card;
a storage card.
17. The apparatus of claim 9 wherein at least one of the first card's connection to the first riser card and the second card's connection to the second riser card corresponds to a PCIe interface.
18. An apparatus, comprising:
a riser card comprising:
a first connector to connect to a first card;
a second connector to connect to a second card;
a first opening through which a third card is to connect to a second riser card;
a second opening through which a fourth card is to connect to the second riser card.
