In the past, data center planners commonly expanded their server capacity to meet increasing workload demands. This method effectively boosted compute, memory, and storage capabilities, catering to evolving requirements.
However, the landscape has shifted with the advent of AI. The era of simply scaling out data centers may be dwindling, especially as traditional methods struggle to keep pace with the specialized needs of AI-powered workloads.
Here’s why:
The Problems With Scale-Out Data Center Architecture in the Age of AI
The conventional scale-out approach in data center architecture involves expanding IT equipment within a facility to meet growing workload demands. This strategy has been prevalent in data center design for an extended period, even if not explicitly labeled as “scale-out.”
Architects typically executed scaling out through methods like:
-
Enhancing Hardware. Substituting older servers with newer models offering increased compute, memory, and storage capabilities.
Given sufficient power and cooling capacities, businesses could scale their infrastructure as required.
