This is how we have taken our infrastructure to the next level
A week of migration. Three months of preparation. A major infrastructure leap we had been wanting to make for a long time.
A few days ago, we completed one of the most ambitious interventions we have ever carried out at GINERNET: the consolidation of equipment that had been spread across 3 racks in 2 different data centers into a single room at Digital Realty Madrid.
The physical result speaks for itself: 800mm racks in a room adjacent to the datacenter’s NOC and freight elevator, giving us intervention and deployment times that would previously have been unthinkable. And with no Meet Me Room in between to interconnect our own equipment.
But the most important change has been the logical one.
After 3 months of research and lab implementation, we deployed a full Spine & Leaf architecture on Arista, with VXLAN as the overlay plane and EVPN as the signaling protocol. This has allowed us to:
✅ Eliminate Spanning Tree: STP disabled across the entire network. No loops, no slow convergence, no blocked ports wasting capacity.
✅ Drastically reduce the ARP broadcast domain: With a distributed anycast gateway on every leaf and an L3VNI for the customer VRF, ARP no longer floods the network. Real scalability for thousands of VMs.
✅ Active-active ECMP toward the core: Traffic is distributed across multiple paths simultaneously, with no standby routes.
✅ Workload mobility between any rack without changing IPs or gateways.
It has been a tough week. But it is one of those weeks where, once it is over, you look back and know it was worth it.

deals?
this is awesome! nice work
Long time no see!
Good to see you growing
Congrats.
The IPMI ports need some out of band management cables.
The SFP ports need some redundancies to protect against switch failure.
The boy in cargo pants needs a belt.
wow.
deals?
@jmginer What is that console cable switch thing?
Congrats, @jmginer!
Congratulations!
Can we get some deals, please?
Looks fantastic, congratulations!
I think he needs bigger pants.
