Data Sheet

The unique adaptive modular rack design of the new x3950 X6 
delivers agility, enabling you to design a solution that meets 
your needs. At the same time, you can realize infrastructure  
cost savings by hosting multiple generations of technology  
in a single platform—without compromising performance or 
capacity. With X6 platforms:

●● ●

You can configure the server to fit the unique requirements  

of your applications and workloads; modify the server at any 
time with selectable modular X6 CPU and memory books. 
You can add, modify or upgrade X6 platforms easily with 
these modular components. These are three types of  
X6 books for each of the major subsystem—storage,  
compute and I/O.

●● ●

You can pay-as-you-grow—this family of IBM servers scales 

from four sockets to eight sockets.

●● ●

You can use IBM Fast Setup software for automated  

provisioning of a cluster of servers; realize time-to-value  
in minutes rather than days.

●● ●

You get agile system design that provides the ability to host 

multiple generations of technology in a single server. 

Resilient enterprise platforms

The growth of new applications has ratcheted database  
processing and business analytics to the top of the list of crucial 
x86 workloads for enterprise businesses. These environments 
demand continuous uptime in order to rapidly achieve the most 
valuable result—massive amounts of business-critical data. The 
enterprise platforms that host these workloads must deliver data 
at a high velocity—with continuous availability.

Through differentiated X6 self-healing technology, the  
x3950 X6 maximizes uptime by proactively identifying potential 
failures and transparently taking necessary corrective actions. 
These unique IBM features include:

●● ●

Advanced Page Retire—proactively protects applications from 

corrupt pages in memory, crucial for scaling memory to 
terabytes.

●● ●

Processor High Availability—allows the platform to maintain 

access to networking and storage and server management 
during a processor failure
