THE COST OF WRONG CHOICES IN NETWORK DESIGN

THE COST OF WRONG CHOICES IN NETWORK DESIGN

Last quarter we walked into a “brand-new” data-centre build that had stalled for weeks. The root cause – wrong switches, wrong topology.

▪️ Juniper Networks QFX series (already end-of-life) were picked for leaf duty – great price per port, but no VXLAN routing.
▪️ To make matters worse, the team linked the two leafs together and gave each leaf only a single uplink to the spine. Result: uneven traffic, unpredicatble resilience and higher long-term costs.

𝐅𝐢𝐱:

After a fast HLD/LLD workshop we swapped to Arista Networks leafs running Broadcom Trident2+ ASICs and rebuilt a true spine–leaf fabric with dual-attached leafs and EVPN-VXLAN multihoming. Racking to production in days, not weeks, no more head-scratching.

An ISP client bought a pair of Juniper Networks MXs two years ago – enough ports then, but no scale headroom. Subscriber growth + new peers = hardware now on life-support and headed for storage. The refresh bill? Way higher than planning the right chassis from day zero.

Cheap today can be expensive tomorrow. Architect with scale and silicon in mind, backed by a solid HLD/LLD, and the implementation just… works. Spend a week on documentation and save months of re-cabling and CapEx.

Have you already battled a deployment that dragged on for weeks and don’t want to step on the same rake again? Or are you kicking off a new build and want to avoid that pain altogether?
