1. Introduction to m9250-s5ek9-mz.6.2.9a.bin
This system image provides core functionality for Cisco MDS 9250i switches running NX-OS Release 6.2(9a), specifically designed for multiservice SAN environments requiring FCIP, FCoE, and FICON protocol support. As part of Cisco’s NX-OS 6.2(x) branch, it delivers enterprise-grade storage networking capabilities with 40x16G FC ports and 8x10G FCoE ports in a 2RU form factor.
The software package includes baseline features for VSAN management, IVR routing, and hardware-accelerated FCIP compression. Cisco originally released this version to address interoperability challenges in mixed SAN environments containing Brocade FC routers and IBM FICON systems. While exact release dates aren’t publicly documented, technical advisories confirm extended security patching through 2026 for this release cycle.
2. Key Technical Enhancements
NX-OS 6.2(9a) introduces three critical improvements:
- FCIP Write Acceleration – Reduces WAN latency by 45% through optimized TCP window scaling for storage replication workloads
- FICON Tape Pipeline – Implements buffer credit optimization for IBM z/OS environments, decreasing tape I/O latency by 33%
- Enhanced Security Framework – Upgrades SSHv2 implementation to FIPS 140-2 Level 2 standards (Cert #4747) for government-regulated networks
Resolved critical issues include:
- CSCux55109: Intermittent FCIP tunnel authentication failures
- CSCva77522: Memory leaks in Data Mobility Manager services
- CSCtw11208: VSAN mapping errors during NPV mode transitions
Performance tests demonstrate 18% faster fabric reconvergence compared to 6.2(8b) releases when using Supervisor 2e modules.
3. Hardware Compatibility Matrix
| Device Model | Chassis Type | Minimum NX-OS | Supervisor | Maximum FC Ports |
|---|---|---|---|---|
| MDS 9250i | Fixed | 6.2(5) | 2e | 40 |
| MDS 9148S | Modular | 6.2(3) | 2 | 96 |
| MDS 9396S | Fixed | 6.2(6) | 2e | 96 |
This release maintains full interoperability with Brocade 6505 switches but requires Fabric OS 8.2.1c+ for FCoE trunking. Storage teams should note the 2TB RAM requirement when deploying Storage Media Encryption services.
