Internet + Speed = Performance

You can't have speed unless it is speed you can use. You want to use the Internet for everything. EtherSAN^TM adapters let you. It's the shortest path for your application to get to the Internet. Finally, your application can talk directly to the Internet. And you'll be astonished to find how much performance is unleashed in your server!

Cluster interconnect products brag about performance, but its performance in moving bits, not Internet applications performance. When you add back in the missing parts they don't mention for the "real world", suddenly the performance vanishes. Its just another esoteric non-Internet network that nobody understands. We already have the Internet - we just need to make it work as we desire.

Silicon TCP^TM - A New Way to do Internet Communications

What gets in the way is the "missing parts" mentioned above - the Internet protocol "stack". InterProphet's patented Silicon TCP directly streams information to the server's application in the minimum time, as the bits on the wire appear. The application can command all at once the full resources of the server, the full Internet bandwidth, and do so more quickly than the server's processor can ever achieve on its own. Technically, Silicon TCP isn't a stack - it’s just a way for stacks to access extreme performance.

Unique EtherSAN Adapter Architecture

Silicon TCP moves the application closer to the Internet by removing delay. EtherSAN adapter architecture improves upon this - it attaches Silicon TCP directly to an application. With a single PCI burst, an Internet packet can hit the wire. ASIC's convert between socket operations of the application and packets. A NIC interface handles low performance traffic thru the operating system.

The EtherSAN Concept

Where an application needs help most is in the enterprise. And the heavy lifting is in two places - messaging and storage. Message latency caps server performance - "all processors wait at the same speed". Storage is rate limited in getting onto the Internet where it can be consumed. The EtherSAN^TM rationalizes LANs so that servers and storage can be combined to serve Internet clients orders of magnitude better.

Only InterProphet's EtherSAN can do this.
