Lenovo System x3950 X6

Today’s mission-critical applications must do more as businesses expand access through new mobile and cloud deployments. Ready access to actionable information is crucial. For this to happen, IT solutions must easily scale performance, manage large masses of data and make information available in real time.

The volume of data and transactions continues to grow exponentially, so businesses remain constrained by a finite set of capital and operational resources. The Lenovo® System x3950 X6 incorporates the sixth generation of enterprise X ARCHITECTURE to help deliver better, more efficient business results.

X6 platforms can produce up to 125 percent faster compute performance than previous-generation systems.1 The X6 portfolio increases virtualisation density and decreases infrastructure costs and complexity. Now you can design faster analytics engines, rein in IT sprawl and deliver information with high reliability. X6 servers are fast, agile and resilient.
