− | + | Servers are linked via Mellanox IB EDR interconnect in a three-level fat tree topology with a 2:1 tapered fat-tree at L1. Astra uses three 540-port switches. Those are formed from 30 level 2 switches that provide 18 ports each (540 in total) with the remaining 18 links going for each of the 18 level 3 switches. The system has a peak Wall power of 1.6 MW. | |
