Distributed and dynamic content replication for server cluster acceleration
First Claim
1. A server comprising:
- a processor;
a memory;
a system area network connection;
a local area network connection; and
software operable on the processor to;
load unique content into the memory from a storage location, receive requests for content over the local area network, service requests for the content in memory, service requests for content located in a memory of another server by obtaining the content over the system area network, and cache content used to service request for content located in the memory of the other server for use in servicing subsequent requests for identical content.

Abstract
The present inventive subject matter relates to the field of network computing, and more specifically to methods, systems, and software for accelerated performance of server clusters, server farms, and server grids. Some such embodiments include methods, systems, and software, that when executing cause content into the memories of servers in a cluster, sharing the contents of the memories amongst all servers in the cluster over a high-speed interconnect to form a high-speed cluster-wide memory. Some such embodiments include servicing content requests from a server that may or may not have the requested content in its local memory, but is able to directly access the requested content in the memory of another server in the cluster over the high-speed cluster wide memory. One such embodiment includes caching the content obtained from the memory of the other server for use in servicing subsequent requests for that content.

8. A system comprising:
-
a networking logic device;
two or more servers, each server operatively coupled to the networking logic device; and
an operating system on each of the two or more servers including one or more software components including executable instructions to;
make the content of each server memory available to the other servers over the networking logic device, and receive and fulfill content requests over the networking logic device with content from a server'"'"'s local memory or from a memory of another server over the networking logic device. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of server operation comprising:
-
priming a memory of a server, wherein the server is a member of a server cluster, wherein the content in the memory of the server is unique to the server amongst all servers in the server cluster;
making the content in the server memory available to other servers in the server cluster over a high-speed interconnection;
receiving requests for content;
fulfilling content requests by retrieving data from the server memory and from memories of one or more other servers over the high-speed interconnection; and
caching content of other servers that has been requested either recently or commonly to provide the server the ability to fulfill requests for cached content locally. - View Dependent Claims (16, 17)

18. A method comprising:
-
distributing web content across a cluster of web servers connected by a first network;
fetching, by a first one of the web servers, web content on demand from a second one of the web servers in the cluster of web servers across the first network; and
caching the web content in the memory of the first one of the web servers. - View Dependent Claims (19, 20)

21. An article comprising a computer-readable medium containing associated information, wherein the information, when accessed, results in a machine performing:
-
receiving, by a first server in a plurality of interconnected servers, a request for content; and
determining if the content is available in a memory of the first server;
if the content is available in the memory of the first server, then responding to the request with the content from the memory of the first server;
if the content is not available in the memory of the first server, then obtaining the content from a memory of one of the servers in the plurality of interconnected servers other than the first server and replicating the content in the memory of the first server. - View Dependent Claims (22, 23)
