The Lenovo System x3850 X6 and x3950 X6 server is a rack model, modular design server, for virtualization, database, and computational intensive computing. The modular design allows for upgrade from a 4-socket (4U-high) to an 8-socket (8U-high) server, using the same building blocks that are used for the 4-socket server. It is the next generation enterprise server based on the Intel Xeon™ EX E7-4xxx v2/v3/v4 and E7-8xxx v2/v3/v4 processor technology. This high-performance, scalable server is ideally suited for enterprise environments that require superior input/output (I/O) flexibility and high manageability.

You must purchase the x3950 X6 4-socket to 8-socket Upgrade kit to upgrade to an 8-socket server. In addition, the upgrade must be performed by a Lenovo approved warranty service provider.

Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of the server. These design features make it possible for you to customize the system hardware to meet your needs today and provide flexible expansion capabilities for the future.

The server comes with a limited warranty. For information about the terms of the warranty and getting service and assistance, see the Lenovo Warranty document that comes with the server.

The server contains next generation technologies, which help increase performance and reliability. For more information, see What your server offers and Reliability, availability, and serviceability.
