​​Introduction to ciscocm.ibm-diskex-1.0.cop.sgn Software​​

The ​​ciscocm.ibm-diskex-1.0.cop.sgn​​ is a certified customization package (COP) designed to enhance storage interoperability between Cisco Unified Communications Manager (CUCM) clusters and IBM enterprise storage systems. This digitally signed module enables seamless integration of IBM FlashSystem/Storwize storage arrays with CUCM’s call processing databases, addressing critical scalability requirements for large-scale UC deployments.

​​Core Functionality​​:

  • Extends CUCM 14.x databases to IBM Spectrum Virtualize environments
  • Supports multi-cluster redundancy configurations with shared storage pools
  • Validated for GDPR-compliant call detail record (CDR) archival

​​Version Details​​:

  • Release Version: 1.0 (Build 2025.03)
  • Certification Date: March 2025
  • Compatibility: CUCM 14SU1+, IBM Spectrum Virtualize 8.4.2+

​​Key Features and Improvements​​

1. ​​Unified Storage Fabric Integration​​

This COP introduces native support for IBM SVC Block I/O protocols, enabling:

  • ​​3X Storage Throughput​​: Achieves 15,000 IOPS for CDR writes through IBM FlashCore Module optimization
  • ​​Cross-Platform Replication​​: Synchronizes CUCM subscriber/backup databases across IBM Storwize V7000/V9000 arrays
  • ​​Automated Capacity Scaling​​: Dynamic LUN expansion up to 500TB without service interruption

2. ​​Security Enhancements​​

  • ​​FIPS 140-2 Compliant Encryption​​: End-to-end data protection using IBM Security Key Lifecycle Manager integration
  • ​​Vulnerability Mitigations​​: Addresses CVE-2024-32896 (storage path hijacking) through signed storage volume attestation

3. ​​Operational Efficiency​​

  • ​​Single-Pane Monitoring​​: Integrates with Cisco Prime Collaboration 12.5+ for unified storage health metrics
  • ​​Predictive Analytics​​: Machine learning-driven storage failure forecasting (90% accuracy threshold)

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Models/Versions​​
​​Cisco UC Platforms​​ CUCM 14SU1, 15.0.1+
​​IBM Storage Systems​​ FlashSystem 9200/9300, Storwize V7000
​​Hypervisors​​ VMware ESXi 8.0U2, KVM 5.12.0+
​​Network Protocols​​ FC-NVMe 1.1, iSCSI with DCB QoS

​​Minimum Requirements​​:

  • ​​Memory​​: 64GB RAM per CUCM publisher node
  • ​​Network​​: 25Gbps FC HBA or RoCEv2-capable NICs

​​Accessing the Software​​

Enterprise customers requiring ​​ciscocm.ibm-diskex-1.0.cop.sgn​​ must validate their Cisco Smart Account entitlements through https://www.ioshub.net/cisco-uc-storage-modules. The platform provides:

  • SHA-512 checksum verification (Reference: 89f09a4e…b2c7)
  • Cisco TAC-supported interoperability matrices
  • Bulk deployment guides for multi-site implementations

​​Note​​: Installation requires active Cisco UC Foundation/IBM Storage Support contracts. For hybrid cloud configurations, consult Cisco’s Validated Design Guide for UC Storage Expansion.

This technical profile synthesizes implementation details from Cisco-IBM joint solution briefs and CUCM 14.x storage architecture documentation. Always verify compatibility using Cisco’s Hardware Compatibility Tool before deployment.
