The 8721 Lenovo Flex System the next generation of blade servers is anchored by the Lenovo Flex System Enterprise Chassis. This platform offers intelligent workload deployment and management for maximum business agility. This chassis delivers high-speed performance complete with integrated servers and networking for multiple chassis management in data center compute environments. Furthermore its flexible design can meet the needs of varying workloads with independently scalable IT resource pools for higher utilization and lower cost per workload. While increased security and resiliency protect vital information and promote maximum uptime the integrated easy-to-use management system reduces setup time and complexity providing a quicker path to return on investment.

The system monitors and manages power usage on all major chassis components so clients have total control over power consumption. The chassis supports N+N or N+1 redundant power supplies configurable in either a single-phase or three-phase power domain and an entirely passive mid-plane to meet reliability needs. The power supplies are 80 PLUS Platinum-certified indicating high energy efficiency. The chassis design also optimizes cooling with cooling zones within the chassis. The system manages the fan modules based on node configuration within the chassis. So the system can increase the speed of certain fan modules to cool potential hot spots and use lower speeds for other fan modules where appropriate.

The Lenovo Flex System Enterprise Chassis is a rack-optimized 10U modular design enclosure that holds up to 14 nodes. A new model includes two 2500-watt Power Modules or two -48 V dc 2500-watt Power Modules standard.
