Quick Take
Quick Take: Cisco Nexus 9364D-GX2A (64×400G) and Arista DCS-7060DX4-32 (32×400G QSFP-DD) are 400G leaf platforms — not peers to 25G 7050X3 / 93180YC-FX3 ToR. Peer on server attachment count, uplink oversubscription, and QSFP-DD optics — not headline Tbps. Shanghai TaoHan Industrial Co., Ltd. supplies both.
When 9364D vs 7060DX4 Actually Matters
Quick Answer: The Cisco Nexus 9364D versus Arista 7060DX4 comparison applies to 400G server or graphics processing unit leaf refreshes, artificial intelligence pod Ethernet fabrics, and estates where both NX-OS and EOS are approved. It does not apply to 25G top-of-rack refreshes, which use a different port map and optics budget.
- Not 100G/25G leaf: Nexus 9300 vs Arista 7050X3 covers 25G ToR — different port map and optics budget.
- Spine is separate: Nexus vs Arista Spine — quote 9500/9300-GX or 7280/7800 on their own BOM line.
- Optics risk: OEM vs MSA optics — QSFP-DD at 400G routinely exceeds switch sticker delta.
- Third column: Juniper QFX5230-64CD (64×400G) or QFX5130-32CD (32×400G) when Junos EVPN estates need a non-Cisco peer — confirm exact suffix on quote.
Port Layout & Density — Confirm SKU Suffix
Quick Answer: The Cisco Nexus 9364D-GX2A ships 64 ports of 400G, while the Arista 7060DX4-32 ships 32 ports of 400G in QSFP-DD form. Density is therefore not equal, so map candidates by servers attached per leaf pair rather than by family nickname, or the quoted switch counts will not be comparable.
| Dimension | Cisco Nexus 9364D | Arista 7060DX4 |
|---|---|---|
| Common leaf SKU | N9K-C9364D-GX2A (confirm suffix) | DCS-7060DX4-32-F / -32C (confirm airflow/DC) |
| 400G port count | 64×400G (QSFP-DD class) | 32×400G QSFP-DD |
| Form factor | 2U fixed (9300-GX2 series) | 1U fixed (7060X4 series) |
| Typical role | High-density GPU/server leaf, AI pod ToR | Moderate-density 400G leaf, aggregation ToR |
| OS | NX-OS (ACI adjacency optional) | EOS |
| HA pattern | vPC / EVPN multi-homing common | MLAG / EVPN multi-homing common |
Naming traps
9364D is not 9364C (64×40/100G QSFP28). 7060DX4 is not 7060DX5-64S (64×400G) — if your brief needs 64×400G on Arista, ask whether 7060DX5-64S belongs on the shortlist instead of forcing a 32-port DX4 comparison. Do not cite aggregate Tbps without showing the port math.
Optics, DAC & Breakouts
Quick Answer: Every 400G port on both the Cisco Nexus 9364D and Arista 7060DX4 lines needs a defined transceiver, direct attach cable or breakout plan. QSFP-DD short reach and data center reach optics, active optical cables and graphics processing unit network card compatibility decide total cost of ownership more than the chassis list price does.
- QSFP-DD: Both platforms use QSFP-DD at 400G — confirm reach (SR, DR, FR) and GPU NIC vendor qualification on the RFQ.
- DAC: 400G passive DAC works for short rack-to-leaf runs; document length and cable gauge on both BOMs.
- Breakouts: If any port runs 4×100G or 2×200G, state it — breakout optics change port budget and oversubscription.
- Spares: Force 10–15% optic spares on both quotes; lead-time gaps break cutover windows.
Optics are not optional at 400G
QSFP-DD modules, AOC cables, and breakout adapters routinely exceed the switch hardware delta. Put line-item counts on both vendor BOMs — see OEM vs MSA optics and Nexus leaf-spine optics BOM.
Oversubscription & Sizing Truth
Quick Answer: Calculate oversubscription from server 400G ports multiplied by leaf count, divided by the 400G uplink ports facing the spine. A 64-port Cisco Nexus 9364D leaf and a 32-port Arista 7060DX4 leaf produce different arithmetic, so equalize the port map and uplink assumptions before ranking either vendor on price.
- Server attachment: Count 400G NICs per rack (GPU servers often need 8×400G per node in AI pods).
- Leaf pairs: Document MLAG/vPC width and how many spines each leaf uplinks to.
- Uplink budget: If 32 server ports need 8×400G uplinks, oversubscription is 4:1 — state the target on the RFQ.
- Density mismatch: Two 7060DX4-32 leaves may attach the same server count as one 9364D-GX2A — price both paths honestly.
NX-OS vs EOS — Ops & Fabric Fit
Quick Answer: Cisco Nexus 9364D and Arista 7060DX4 both run modern EVPN-VXLAN leaf-spine designs, so the fork is day-two operations rather than raw port speed. NX-OS and Application Centric Infrastructure gravity sits on one side, EOS and CloudVision automation on the other. Choose the operations plane the network team already runs.
| Dimension | Cisco Nexus 9364D | Arista 7060DX4 |
|---|---|---|
| OS | NX-OS | EOS |
| Ops plane | ACI / Nexus Dashboard / NX-OS automation | CloudVision / EOS automation adjacency |
| Leaf HA | vPC designs common | MLAG designs common |
| Overlay | EVPN-VXLAN leaf-spine common | EVPN-VXLAN leaf-spine common |
| Lean Cisco when | NX-OS runbooks, ACI skill, existing Nexus 9300/9364 estates | — |
| Lean Arista when | — | EOS runbooks, CloudVision, existing Arista leaf/spine standardization |
- Still quote Juniper when: Junos EVPN skill or QFX5230/QFX5130 estates define migration risk — one line on the RFQ, not a full third bake-off unless TCO is close.
- AI fabric note: GPU pod designs often standardize one vendor per pod; dual-source across refresh waves for commercial leverage.
Spine RFQ — Keep Leaf and Spine Separate
Quick Answer: Quote Cisco Nexus 9364D or Arista 7060DX4 leaf bills of materials on their own line. Price Nexus 9500 or 9300-GX and Arista 7280 or 7800 spine part numbers separately, cross-referencing uplink transceiver counts and oversubscription arithmetic between the two lines so leaf and spine port budgets actually reconcile.
- Leaf line: Chassis, power/airflow suffix, EOS/NX-OS licenses, QSFP-DD downlink optics, leaf-to-server DAC/AOC.
- Spine line: Spine chassis or fixed SKU, line cards if modular, leaf-to-spine uplink optics (often 400G QSFP-DD), spine-to-spine if applicable.
- Cross-reference: Uplink count per leaf × leaf count must match spine port budget — document on both BOMs.

RFQ Checklist — Dual 400G Leaf BOM on One Brief
Quick Answer: Issue one 400G fabric brief, then request Cisco Nexus 9364D and Arista 7060DX4 line items priced with equal transceivers and software licenses, keeping the spine on its own line. Add a Juniper third column when Junos skill exists. State leaf count, server port count per leaf pair and the oversubscription target.

Use SKU Lookup, then submit the dual-vendor brief on rfq.html.
Real-World Deployment Scenarios
Quick Answer: Map the three scenarios below to your workload, facility, and commercial constraints before freezing CapEx. Equal-BOM RFQs should cite which scenario drives the shortlist.
Scenario 1: 800G RoCEv2 Train Pod (Latency Bound)
Workload Profile: Rail-optimized GPU pods needing deep buffers and DLB behavior.
Architectural Fit: Compare 7060-class and 9364D on buffer, ECMP/DLB, and optics BOM—not marketing Tbps alone.
Scenario 2: Dual-Vendor Mandate (Risk Bound)
Workload Profile: Enterprise requires two spine vendors on paper.
Architectural Fit: Keep leaf/spine roles consistent; mixed spines need explicit failure-domain testing.
Scenario 3: Ops Toolchain Lock (Skill Bound)
Workload Profile: NetOps standardized on CloudVision or Nexus Dashboard.
Architectural Fit: Weight day-2 tooling equally with dataplane latency when freezing the spine family.
Frequently Asked Questions
Quick Answer: Compare Cisco Nexus 9364D and Arista 7060DX4 on server attachment and oversubscription rather than headline port counts, equalize QSFP-DD transceiver quantities, keep the spine on a separate quotation line, and then let NX-OS versus EOS operations decide. Neither leaf wins universally once density and optics assumptions are stated honestly.
Not universally. Nexus wins for 64×400G density in NX-OS/ACI estates. Arista wins for 32×400G EOS estates with lower per-leaf port needs. Dual-RFQ matched fabric briefs.
Only when you document server count per leaf pair and oversubscription. For 64×400G on Arista, confirm whether 7060DX5-64S belongs on the shortlist.
No. Leaf and spine are separate line items with cross-referenced uplink optics. See the Nexus vs Arista spine guide.
Submit one RFQ with the dual-vendor checklist above.
Key Takeaway
Key Takeaway: Nexus 9364D and Arista 7060DX4 are 400G leaf platforms with different port density — not 25G ToR peers. Win on optics honesty, oversubscription math, and separate spine lines — then standardize. Shanghai TaoHan Industrial Co., Ltd. supplies both with competitive pricing and configuration support for global buyers.
