cables wasted for inter-switch connectivity. HyperScale combines the best of Hypercube
(price, simplicity, cabling) and Fat-tree (performance).
HyperScale features:

Each 324 node scalable unit is fully independent (failures, upgrades)

Lowest latency of 400 nanoseconds (vs. 500/750 nanoseconds)

There are fewer cables to wire

Ultimate application performance (large non-blocking islands and minimize application
specific tuning/layout).
