720865-B21 Use Case
Rapid Hot-Swap Server Replacement in Enterprise Data Centers
When IT administrators perform hot-swap maintenance on HP ProLiant Gen8 2U servers, the 720865-B21-2U Cable Management Arm PL=SI keeps network and power cables organized and secured outside the rack. This reduces mean time to repair (MTTR) by up to 30%, prevents accidental cable disconnections, and ensures continuous application uptime.
Optimized Airflow and Cooling in High-Density Racks
In high-density virtualization environments, uncontrolled cable bundles can block airflow and drive up cooling costs. Installing the 720865-B21-2U Cable Management Arm on each 2U Gen8 chassis maintains neat cable paths, improves rack airflow by 25%, and helps data centers meet ASHRAE thermal guidelines for energy efficiency.
Standardized Cable Management for Multi-Site IT Deployments
Global enterprises deploying HP Gen8 servers across multiple sites need consistent rack standards to simplify audits and compliance. The 720865-B21-2U Cable Management Arm PL=SI delivers a uniform cable routing solution that accelerates rack build-outs by 40%, enforces best-practice documentation, and reduces on-site installation errors.
