Quick Take
要点速览： 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
速答： 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
速答： 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 Do not cite aggregate Tbps without showing the port math.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
速答： 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
速答： 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
速答： 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
速答： 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
速答： 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.
What to put on the RFQ
- Leaf count, 400G server/GPU port count per leaf pair
- Exact SKU: N9K-C9364D-GX2A vs DCS-7060DX4-32 (airflow/DC suffix)
- Oversubscription target and spine uplink speed/count
- HA pattern: vPC vs MLAG (state both)
- EVPN-VXLAN requirements (or L2/L3 only)
- Cisco: NX-OS/support term, ACI licenses if used
- Arista: EOS/support term, CloudVision if used
- Optics: QSFP-DD DAC/AOC/SR/DR counts + spares per port
- Separate spine BOM line (9500/9300-GX vs 7280/7800-class)
- Optional Juniper QFX5230-64CD or QFX5130-32CD third column
- Lead time: stock vs ATP; quote validity window
Use SKU Lookup, then submit the dual-vendor brief on rfq.html.
真实应用场景
速答： 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.
常见问题
速答： 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
核心结论： 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.
