681842-B21 Use Case
Enterprise Virtualization and Server Consolidation
A global financial services firm deploys 16 VMware ESXi hosts within a single HP BLc7000 1PH 6PS 10Fan 16 IC Plat Encl to replace 32 rack servers. This setup delivers 50% rack-space savings, 40% lower power consumption, and unified management via HPE OneView—accelerating VM deployment and reducing operational overhead.
High-Performance Computing Cluster for Research
A university research lab configures 16 half-height HPC blades in the HP BLc7000 enclosure, interconnected over 10 GbE and InfiniBand fabrics. The integrated 10-fan cooling and six 2 kW power supplies maintain optimal thermals under peak load, boosting compute density by 70% and reducing latency for large-scale simulations.
Private Cloud Infrastructure and On-Demand Provisioning
An enterprise IT department builds a private IaaS cloud on HP BLc7000 1PH 6PS 10Fan 16 IC Plat Encl hosting hyperconverged storage and compute blades. Automated provisioning through HPE OneView and Synergy Composer cuts VM provisioning time from days to minutes, improves resource utilization by 35%, and enforces policy-driven compliance.
