Abstract

A solution enabling the practical use of very large amounts of memory, external to a host computer system. With physical locality and confinement removed as an impediment, large quantities of memory, here before impractical to physically implement, now become practical. Memory chips and circuit cards no longer must be installed directly in a host system. Instead, the memory resources may be distributed or located centrally on a network, asconvenient, in much the same manner that mass storage is presently implemented.

Claims

1. A device, comprising:

a module comprising a memory mapped resource configured to enable multiple memory devices with solid state computer addressable memory to be distributed over an area and be accessible by multiple computers, wherein the memory devices and the computers are operably interconnected via transmission links and switches.

2. The device as specified in claim 1, where the memory mapped resource is not at the block or file level.

3. The device as specified in claim 1, where the memory mapped resource is byte or bit oriented and operably compatible with the PCI or PCI Express protocol.

4. The module as specified in claim 1, wherein the memory mapped resource is configured to enable the plurality of solid state memory devices and a plurality of computer servers to be operably interconnected over a wide area using longer distance transmission and switching means than possible using a local computer bus.

5. The module as specified in claim 1, wherein the memory mapped resource is configured to enable long distance transmission and utilize switching techniques, the techniques selected from the group of:

Ethernet, Internet, and a computer bus adapted for extended distances.

6. The module as specified in claim 5 wherein the memory mapped resource is configured to utilize i-PCI as a foundational enabling memory-mapped I/O expansion and virtualization protocol.

7. The module as specified in claim 4 wherein the memory resource is configured to enable computer memory addresses to mapped onto other types of addresses, including Ethernet addresses, IP addresses, addresses for transmitting and switching devices, and hardware.

8. The module as specified in claim 1 wherein the memory resource is configured to enable computer addressable memory to be pooled on a network and shared by multiple computer servers via memory-mapped access to enable flexible, scalable, and reliable memory mapping and sharing.

9. The module as specified in claim 1, wherein solid state computer addressable memory is located as Directly Attached Memory.

10. The mechanism as specified in claim 1, wherein the solid state computer addressable memory is located on an Ethernet.

11. The module as specified in claim 1, wherein the solid state computer addressable memory is located on the Internet.

12. The module as specified in claim 5 wherein the memory mapped resource is configured to operably utilize an Ethernet network comprising a direct connect, LAN, WAN, or WPAN arrangement or any combination thereof.

13. The module as specified in claim 1 wherein the memory mapped resource is configured to encapsulate PCI Express packets within TCP/IP and/or Ethernet packets.

14. The module as specified in claim 1 wherein the memory mapped resource is configured to categorize different types of the memory device memories into tiers.

15. The module as specified in claim 14 wherein the memory mapped resource is configured to operably interconnect one said computer with one said memory device as a function of the memory device tier.

16. The module as specified in claim 14 wherein the module is configured as a host bus adapter.

17. The module as specified in claim 1 wherein the memory devices are configured to be enumerated by a client system and appear to the computer as PCI Express addressable memory.

18. The module as specified in claim 13 wherein the module is configured to enable virtualization of the computer'"'"'s native I/O system architecture via the Internet and LANs.

19. The module as specified in claim 1 wherein the module is configured to enable the computer to access data from one of the memory devices directly using memory addressing,

20. The module as specified in claim 19 wherein the module further includes an adaptation layer configured to translate a memory address of data by one said computer into requisite means of data transport addressing, including IP addresses and Ethernet addresses.
