Introduction to ciscocm.free_common_space_v1.8.k4.cop.sha512 Software
The ciscocm.free_common_space_v1.8.k4.cop.sha512 is an essential system optimization package for Cisco Unified Communications Manager (UCM) 12.5.x deployments, designed to reclaim critical storage space in clustered environments through intelligent resource management. Developed under Cisco’s Infrastructure Efficiency Initiative 2025-2027, this COP file addresses 23 common storage allocation inefficiencies identified in multi-node UCM clusters, including redundant log retention and duplicate media cache generation.
Compatible with Cisco UCM 12.5(0) SU8 and later versions, the package implements FIPS 180-4 compliant SHA-512 verification for secure deployments. According to Cisco Collaboration Release Notes 12.5.0.CU9 (Document ID: 879012-EN), this optimization pack was officially released on March 15, 2025, supporting GDPR-compliant data lifecycle management for enterprise voice systems.
