The issue though is that each server itself is starting to have 100 Gbit network connections, not just the rack itself.

- zamadatix 6y agoBandwidth isn't the problem, latency is. Each server could have 400 terabit interfaces and you'll still have garbage iops compared to local pcie on a laptop for reasonable depth.
