Juniper QFX5130 vs Arista 7060X: 100/400G Spine and Leaf Switching Compared

Both deliver line-rate 400G EVPN-VXLAN on comparable Broadcom silicon, so raw forwarding is close to a tie. The QFX5130 wins for teams that want intent-based fabric automation via Apstra and an open, standards-first stack; the 7060X wins for shops already standardized on EOS and CloudVision.

The QFX5130-32CD is built on Broadcom Trident 4, delivering 25.6 Tbps and 32 ports of 400GbE in 1U. The Arista 7060X5 family uses Broadcom Tomahawk-class silicon, with 1U 32x400G and 2U 64x400G models. Because both lean on Broadcom merchant silicon, the differentiation is in software, not the chip.

Junos OS Evolved is a disaggregated, state-driven OS with a central database that improves resilience and telemetry. Arista EOS is a single-image, Linux-based OS with a long track record in hyperscale environments. Both support EVPN-VXLAN, MACsec, and rich automation; the choice usually follows your existing operational model.

Both fully support Layer 2 and Layer 3 EVPN-VXLAN for spine-leaf fabrics. Juniper pairs the QFX5130 with Apstra for intent-based EVPN design and continuous validation, while Arista uses CloudVision for telemetry and change control. For automated EVPN lifecycle management, Apstra is a standout.

Yes. The QFX5130 is part of HPE Juniper Networking, so it aligns with HPE servers, storage, and a unified support relationship. That single-vendor option can simplify procurement, warranty, and lifecycle management for enterprise and public-sector buyers.

TAA-compliant Juniper QFX5130 configurations are commonly available, and as an authorized HPE Juniper Networking reseller we can source them through federal channels. We can also source Arista 7060X where contract terms and TAA requirements allow, and advise on the right SKU for your vehicle.

Both operate in the low-microsecond range, well suited to fabric spine roles. Arista publishes sub-microsecond cut-through latency (around 825 ns at 400G) on 7060X5 models. For most EVPN-VXLAN data center fabrics the difference is negligible; for latency-sensitive HPC or AI fabrics, validate against your specific traffic profile.

Arista's 7060DX5-64 carries up to 114 MB of buffer, useful for bursty, incast-heavy traffic. The QFX5130 uses Trident 4's on-chip shared buffer. If your workload is highly incast-prone, weigh buffer depth; for typical enterprise fabrics, both are sufficient and software features matter more.
