What Makes DS-C9710 the Core of Modern SAN Architectures?
The DS-C9710 is Cisco’s flagship multilayer director for storage area networks (SANs), designed to handle 768 ports per chassis with 6.144 Tbps full-duplex Fibre Channel switching capacity. Unlike previous generations like MDS 9500, it supports mixed 16/32/64 Gbps Fibre Channel and 40/100 Gbps FCoE in a single chassis, enabling seamless integration of legacy and next-gen storage protocols.
Key innovations include:
- Fabric 3 modules: Triple the switching bandwidth of Fabric 2 (440 Gbps vs. 220 Gbps per slot)
- Cisco TrustSec FC encryption: 16 Gbps line-rate hardware encryption for data-at-rest and in-motion
- Multi-hop FCoE support: Unified management for converged LAN/SAN traffic across 10/40/100GbE
DS-C9710 vs. MDS 9509: Evolution of Enterprise Storage Switching
| Feature | DS-C9710 | MDS 9509 |
|---|---|---|
| Max Port Density | 768 FC/FCoE ports (48-port 16G modules) | 336 FC ports (48-port 8G modules) |
| Switching Capacity | 12.288 Tbps (Fabric 3 modules) | 2.88 Tbps |
| Energy Efficiency | 0.8W per 16G port | 2.1W per 8G port |
| Protocol Support | FC, FCoE, NVMe-oF, iSCSI, FCIP | FC, FCoE, FCIP |
| Diagnostics | Cisco GOLD with predictive analytics | Basic OHMS monitoring |
This table reveals how the DS-C9710 eliminates traditional SAN bottlenecks through 4x higher port density and 50% lower power consumption compared to MDS 9500-series directors.
Deployment Scenarios and Configuration Best Practices
Three critical use cases define the DS-C9710’s operational value:
-
Hyperscale Storage Pools
- Supports 1:8 oversubscription ratios for cost-effective HDD/SSD tiering
- Port bandwidth partitioning enables dedicated 64G links for NVMe arrays while sharing 16G pools for tape libraries
-
Multi-Cloud Data Fabric
- Cisco DCNM integration manages 150,000+ devices across hybrid infrastructures
- SRv6 support simplifies policy enforcement between on-prem FC and AWS/Azure FCoE clouds
-
Mainframe Modernization
- FICON acceleration reduces IBM z16 latency by 40% vs. MDS 9700
- Cross-platform zoning allows simultaneous FC/FCoE access for z/OS and Linux workloads
For optimal performance, configure N+1 power supplies and dual supervisor modules when deploying mission-critical workloads. Verify compatible line cards at itmall.sale’s Cisco SAN portfolio.
The DS-C9710 redefines enterprise storage networking by merging carrier-grade reliability with web-scale flexibility. Its true breakthrough lies in protocol-agnostic architecture – a future-proof foundation for AI-driven storage automation and quantum-safe encryption. Enterprises prioritizing TCO reduction without compromising performance should view this director not as an upgrade, but as the backbone of their next-decade data strategy.
