Quick Take
要点速览： Cisco MDS 9700 (9706/9710/9718 modular directors, NX-OS SAN) and Brocade X7 (X7-4/X7-8 modular directors, Fabric OS) are peer director-class platforms — not another G720 fixed-switch article. Peer them on chassis tier, line-card generation, ICL/ISL design, and optics — not OS stickers. Equalize modular BOM lines and support years. Shanghai TaoHan Industrial Co., Ltd. supplies both paths.
When MDS 9700 vs Brocade X7 Actually Matters
速答： The Cisco MDS 9700 versus Brocade X7 director comparison applies when port density, fabric consolidation or director-scale growth pushes a Fibre Channel storage area network past fixed-port switches, typically hundreds of ports per fabric with modular expansion room reserved. Below that scale, fixed-port switches remain the cheaper and simpler bill of materials.

This Is Not Another G720 Article
速答： Brocade G720 and fixed-port Cisco MDS switches are single-chassis part numbers with published port counts. MDS 9700 and Brocade X7 are modular directors whose maximum ports depend on chassis size plus the line-card or port-blade mix installed. Quote directors and fixed switches on separate request-for-quotation lines so the counts stay comparable.
| Class | Examples | RFQ shape |
|---|---|---|
| Fixed-port switch | Brocade G720, MDS 9148T class, Dell DS-7720B | Chassis + port licenses + optics — one appliance line |
| Modular director | MDS 9706/9710/9718, Brocade X7-4/X7-8 | Chassis + supervisors + fabric modules + line cards + power + optics |
| When to use directors | Consolidate many edge switches; need slot growth; rack-scale port density | Director BOM on its own spreadsheet section |
Do not merge RFQ lines
A quote that lists “48-port G720” beside “MDS 9718” without line-card detail is not comparable. Fixed switches and directors should appear as separate sections on the same fabric brief — edge/mid on one line, core/director consolidation on another.
Architecture Fork — NX-OS SAN vs Fabric OS
速答： Cisco MDS 9700 and Brocade X7 both deliver enterprise modular Fibre Channel directors, so the decision fork is operational rather than capability. It turns on NX-OS versus Fabric OS runbooks, inter-chassis and inter-switch link tooling, and how the network operations center already runs large storage area network fabrics today.
| Dimension | Cisco MDS 9700 series | Brocade X7 director |
|---|---|---|
| OS | NX-OS (MDS SAN release train) | Fabric OS (FOS) |
| Chassis tiers | MDS 9706, 9710, 9718 (slot count scales) | X7-4 (8U), X7-8 (14U) |
| Modular BOM | Supervisors, Fabric-3 crossbar modules, 48-port line cards | Control processor blades, CR blades (ICL), port blades (FC32/FC64 families) |
| Scale-out pattern | ISL/port-channel between directors and fixed switches | UltraScale ICL between X7 chassis; blade-dependent port math |
| Speed generations | 16G / 32G / 64G line cards (confirm NX-OS release on quote) | 32G and 64G port blades; Flexport FCoE on select blades |
| Optics | SFP+/SFP-DD per line card — must itemize | SFP+/SFP-DD/QSFP per blade — must itemize |
Chassis & Slot Honesty
速答： Published maximum port counts for Cisco MDS 9700 and Brocade X7 directors assume a full chassis filled with specific line cards or port blades. The request for quotation must therefore state the chassis part number, the slot budget, and how many slots are reserved for growth versus inter-chassis or inter-switch links today.
| Chassis | Cisco MDS 9700 path | Brocade X7 path |
|---|---|---|
| Mid director | MDS 9706 — 4 line-card slots; Cisco publishes up to 192 FC ports (generation-dependent) | X7-4 — 4 horizontal port-blade slots; Broadcom publishes up to 256 64G device ports (blade-dependent) |
| Large director | MDS 9710 — 8 line-card slots; Cisco publishes up to 384 FC ports | X7-8 — 8 vertical port-blade slots; Broadcom publishes up to 512 64G or 384 64G device ports depending on blade type |
| Max scale chassis | MDS 9718 — 16 line-card slots; Cisco publishes up to 768 FC ports with 64G line cards | X7-8 is the large-tier peer — confirm ICL blade slots vs device port blades on quote |
| Supervisor / control | 2 supervisor slots (Supervisor-4 class on current builds) | Redundant control processor blades in dedicated slots |
| Fabric / crossbar | 6 crossbar fabric module slots (Fabric-3 class) | CR64 core routing blades for Gen 7 ICL (slot count varies by chassis) |
Line Cards & Port Blades
速答： Director port density is a function of the module installed: 48-port 16G, 32G or 64G line cards on Cisco MDS 9700, and FC32-48, FC32-64, FC64-48 or FC64-64 blade families on Brocade X7. Match speed generation and module count on both quotes, otherwise the port totals compared are not equivalent.
| Intent | Cisco MDS 9700 line cards | Brocade X7 port blades |
|---|---|---|
| 32Gb fabric today | 48-port 32G FC line cards (confirm DS-X module SKU) | FC32-48 / FC32-64 class blades |
| 64Gb array/HBA path | 48-port 64G FC line cards (confirm NX-OS release + optics) | FC64-48 / FC64-64 class blades |
| FCoE adjacency | FCoE modules available on 9700 family (separate RFQ line) | Flexport on FC32-64 blades for FCoE breakout modes |
| Extension / long distance | FCIP/extension modules — separate from port line cards | SX6 extension blades — separate slot budget |
Optics per line card
Each 48-port line card needs 48 transceivers (plus spares) per fabric. Director optics spend often exceeds chassis delta — itemize SFP+/SFP-DD SKUs, ISL/ICL optics, and spares on both paths. See OEM vs MSA optics.
Ops & Fabric Scale Fit
速答： Director choice follows existing storage area network operations skill and fabric topology. Estates built on NX-OS zoning and VSAN practice lean toward Cisco MDS 9700, while Fabric OS estates using UltraScale inter-chassis links lean toward Brocade X7. Staff skill and current support entitlements matter as much as slot and port arithmetic.
- Lean MDS 9700 when: Cisco SAN runbooks, NX-OS skill, existing MDS directors, and DCNM-era tooling dominate day-2 ops.
- Lean Brocade X7 when: FOS estates, Brocade SANnav-class tooling, UltraScale ICL mesh designs, or multi-OEM SAN standards fit procurement.
- Keep fixed switches too: Directors often consolidate edge — still quote G720/9148T class for remote sites on a separate RFQ line.
- TruFOS / support: Brocade entitlement can block FOS upgrades — put support years on the RFQ before PO, not after install.
Director BOM Structure — Separate From Fixed Switch RFQ
速答： Split the Fibre Channel bill of materials spreadsheet into three sections: fixed-port edge and mid-fabric switches, the modular director chassis stack with supervisors, fabric modules and line cards, and shared optics with spares. Never roll Cisco MDS 9700 or Brocade X7 directors into a single switch count line.
Section B — modular director lines (both vendors)
- Chassis (9706/9710/9718 or X7-4/X7-8)
- Supervisors / control processor blades (qty 2 redundant)
- Fabric crossbar modules (MDS Fabric-3) or CR blades (X7 ICL)
- Line cards / port blades — qty, generation, port count per module
- Power supplies, fan trays, rack kits
- Software licenses (enterprise/advantage tiers — confirm on quote)
- Support term (3 or 5 years, matched)
- Optics: per-line-card transceivers + ISL/ICL + spares
Section A — fixed switch lines (reference)
G720, MDS 9148T, DS-7720B — quote on MDS vs G720 guide lines. Do not substitute director chassis for edge port counts without documenting topology.
RFQ Checklist — Dual Director BOM on One Brief
速答： State one director brief, then request Cisco MDS 9700 and Brocade X7 modular line items priced against equal chassis fill, line-card generation, transceiver counts and support years before deciding. Keep fixed-port switches in a separate section of the same request, and name the target port count per fabric including growth reserve.
What to put on the RFQ
- Target FC port count per fabric (A/B) including growth reserve
- Chassis tier: 9706 vs 9710 vs 9718 ↔ X7-4 vs X7-8
- Line-card/blade generation: 32Gb vs 64Gb; qty per chassis
- ICL/ISL count, speed, and optic type (UltraScale vs classic ISL)
- Slots reserved for future line cards vs filled today
- Array and HBA models attaching (speed generation proof)
- Cisco: chassis SKU, supervisor, Fabric-3 modules, line-card SKUs, NX-OS/support
- Brocade: chassis SKU, CP blades, CR blades, port blade SKUs, FOS/support, TruFOS
- Optics: transceiver SKUs per line card + ISL/ICL + spares (both paths)
- Fixed-switch section: G720/9148T if edge sites stay separate
- Rack, power, and airflow (front-to-back on both families)
- Migration window from legacy directors or multi-switch sprawl
Use SKU Lookup, then submit the dual-vendor director 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: Dual-Datacenter Bank Core (Availability Bound)
Workload Profile: Hitless upgrades and deep telemetry on dual fabrics.
Architectural Fit: Score MDS 9700 vs X7 on supervisor redundancy, ISL scale, and ops toolchain—not port stickers alone.
Scenario 2: Brocade-Heavy Installed Base (Skill Bound)
Workload Profile: Existing FOS expertise and TruFOS optics policy.
Architectural Fit: X7 usually minimizes retraining; MDS wins when NX-OS/DCNM skill and Cisco enterprise agreements dominate.
Scenario 3: NVMe-oF Front-End Growth (Protocol Bound)
Workload Profile: Arrays exposing more 64Gb NVMe/FC hosts.
Architectural Fit: Validate line-card and optics roadmaps on equal BOM before freezing the director family.
常见问题
速答： Compare Cisco MDS 9700 and Brocade X7 as modular directors on chassis tier, line-card or port-blade generation and transceiver counts, not against fixed-port Brocade G720 sticker port numbers. Quote both vendors with equal support years before standardizing, because entitlement gaps and optics spend usually decide the outcome more than chassis price.
Not universally. MDS wins for many Cisco NX-OS SAN estates. X7 wins for many FOS estates with UltraScale ICL designs. Dual-RFQ matched director briefs with modular BOM detail.
No — G720 is fixed-port class. This page covers modular directors. Use the MDS vs G720 guide for edge/mid fabric; use this page for director consolidation.
Yes as large-chassis peers when line-card generation, ICL/ISL design, and optics match. Confirm exact module SKUs — published max ports vary by line card.
Submit one RFQ with chassis, line-card, and optics on separate lines.
Key Takeaway
核心结论： MDS 9700 and Brocade X7 are peer modular FC directors — not G720 fixed switches. Win on chassis/line-card honesty, optics itemization, and separate RFQ sections for edge vs director — then standardize.
