Describes the basic building blocks to high availability, high density datacenter design. My team at Sun specialized in HPC datacenter design, build. We also specialized in what went into that datacenter (compute, storage, network).

How Many Racks Are Needed?
• What is the Compute Requirement per Rack (KW)?
• Are their redundant racks?
• Is physical separation required between groups of racks?
• How many Pods are needed?
• What’s a Pod?

11. Design: The Pod Architecture
A group of racks or benches with a common hot or cold aisle used as a building block to simplify
datacenter design for power, cooling, & cabling
Vendor independent,
slab or raised floor, flexible,
scalable, high density

How Many Pods Are Needed?
• A Pod is commonly 12 racks back to back with an IDF rack in
the middle of each row for a 24 rack pod.
• Cooling can be achieved in-row and/or overhead.
• Power is distributed by a series of plug-in bus duct overhead.
• Two rows of bus duct will be required for Tier IV

13. How Many Pods Are Needed?
• Quantity of Pods
• Quantity of Racks
