1. Introduction to ciscocm.free_common_space_v1.8.k4.cop.sha512
This cryptographically validated storage optimization package provides automated disk space reclamation for Cisco Unified Communications Manager (CUCM) 14.0(1)SU8 deployments. Designed for enterprises requiring NIST SP 800-209-compliant storage management, it enables intelligent cleanup of transient media files while preserving critical call detail records (CDRs) and diagnostic logs.
The v1.8.k4 version introduces SHA-512 hashing for audit trails and optimizes space recovery algorithms for HyperFlex HX280c storage nodes. Compatible with CUCM clusters running 14.0(1)SU6 or later, it supports multi-tenancy environments across Cisco UCS C480 M7 servers and Intersight managed infrastructure.
2. Key Features and Improvements
2.1 Storage Optimization
- Dynamic Media Purging: Automates removal of expired voice/video recordings per ISO 27001 retention policies
- NUMA-aware Defragmentation: Reduces disk fragmentation by 42% in clustered deployments
- Predictive Capacity Planning: Generates 90-day storage consumption forecasts
2.2 Security & Compliance
- FIPS 140-3 validated cryptographic erasure of decommissioned storage blocks
- GDPR/PII-aware media scanning with dual-layer metadata verification
- TLS 1.3 encrypted audit log transmission to Cisco Prime Collaboration
2.3 Performance Enhancements
- 35% faster cleanup cycles compared to v1.7
- 18% reduction in I/O latency during peak hours
- Adaptive resource throttling for mixed HDD/SSD environments
