Abstract

Disclosed is a split level mezzanine card form factor which enables flexible I/O in high density blade servers. This I/O card is a mezzanine style card located between parallel planars, above and below, thus named a "split-level mezzanine". The I/O card connects to both upper and lower planars, with a third connection to a mid-plane.

Split-level Mezzanine I/O Card Form Factor for High Density Blade Servers

High density server offerings are becoming an increasingly popular product in the server market, specifically in the blade (or Information Technology Element (ITE)) market. High density blade servers require half of the infrastructure cost of standard blade servers, without sacrificing Central Processing Unit (CPU) performance or memory capacity.

In high density blade servers, board space is limited, but flexible input/output (IO) is critical for easy integration into data center environments and maintaining a competitive advantage. There are no known solutions for flexible I/O in high density blade servers. Current offerings enable only a single I/O fabric which is built into the base planar.

This invention is for a split level mezzanine card form factor which enables flexible I/O in high density blade servers. This I/O card is a mezzanine style card located between parallel planars, above and below, thus named a "split-level mezzanine". The I/O card connects to both upper and lower planars, with a third connection to a mid-plane.

This solution is at a great advantage over the current single I/O fabric of current high density blade servers for the following reasons:


• Allows for flexible I/O fabric solutions. This disclosure allows multiple I/O cards to be developed, allowing multiple I/O configurations in the system. Increases the board space available for I/O components.


• Allows fo...
