The scalable compact rack server
NEC Express5800/R120b-2
Scalable and green
The Express5800/R120b-2 is a dual-socket 2U rack server
enabling high-density mounting and combining outstanding
performance, reliability, energy saving parts and green technology.
In addition, the platform features internal scalability and large
memory capacity for future growth.
For compute intensive environments
Perfect for virtualization solutions, database servers, consolidation
of business-critical applications, Web servers which all process
high volumes of data in the background of their primary tasks.
