The major cloud vendors have their own data centers & do not need to deal with space or power limits at a rack unit. They have the entire data center worth of space and power supply to work with.
- jonatron 3y agoIf the data centre is owned by digital reality, equinix, telehouse, etc, is it really theirs? https://aws.amazon.com/directconnect/locations/ https://aws.amazon.com/directconnect/locations/
- arrakeenrevived 3y agoDirect Connect locations are not the locations where the main region data centers are. AWS has a network link from their DC to Equinix, etc to make it easier for customers who are in Equinix's colo to make a direct connect to the AWS network.
- toast0 3y agoAll data centers have space and power/cooling limits. If you're in someone else's DC, they are usually going to quote you as per-rack power, but if you really want you can probably convince them to let you use 2 racks worth of power in one rack and hold a second rack empty. In owned and operated DCs, it's kind of similar, if the DC was built a while ago, as server power density has increased, a significant portion of the floor space may be unusable for racks. 10-20 years ago, 1U and blades made a lot of sense because space was a major constraint; now 2U or larger can make sense because 1U has a lot of tradeoffs for size, and power is the bigger constraint. If space density is still needed, 2 nodes in 2u or similar narrow but tall configurations provide a more square profile that allows generating airflow with larger fans which is more efficient than the 40mm fans needed in 1U systems.
