With the current model, existing resources cannot be leveraged because the server blade is the basic unit of partition. This has led to a complete reorganization in the hyper-scaler data centers to use compute resources more efficiently, and the idea now is beginning to percolate through other data centers. “Amazon, Microsoft, and Google are operating at a much bigger scale,” said Rakesh Renganathan, director of marketing, power management, power and sensors solutions business unit at Infineon.

“A few years back, they were buying servers from PC vendors. The scale is big enough that simple architectural changes that they can influence and control today can turn into millions of dollars of savings.”Īdding that flexibility sounds straightforward enough, but it represents a massive change. “Everyone’s trying to make data center resources a service on tap - both on the software side and now adding hardware as a service on tap,” said Arif Khan, group director of product marketing for PCIe, CXL and interface IP at Cadence. There is a new movement, generally referred to as “data-center disaggregation,” that moves away from the server as the basic unit.

Instead, various resources are pooled together and allocated as jobs require. But composing and interconnecting the resources isn’t trivial.

The idea of a data center started as a place where multiple servers could be co-located and called on demand for computing.Īnd a move to this architecture must be done in an evolutionary manner, without disrupting the older architecture resources already in place. As the computing done in data centers has become more intensive, however, it might exceed the capacity of a single server.
