Data Sheet

This business-critical, enterprise-class server leverages unique 
IBM eXFlash memory-channel storage to deliver an exceptional 
level of performance and value to clients. eXFlash memory-
channel storage offers significantly lower write latency than any 
other flash offering on the market—less than 5 microseconds 
write latency.

 As more eXFlash DIMMs are added, IOPS 

increase, yet latency does not increase.

With IBM eXFlash memory-channel storage, you gain consis-
tent performance even if you are running mixed workloads:

●● ●

The on-memory-bus design alleviates potential  

I/O contention

●● ●

Databases from 200 GB to 12.8 TB have deterministic 

response times and consistent performance 

eXFlash memory-channel storage gives you the confidence to 
support several times more virtual machines per server without 
degradation of service, and they are ideal for large databases 
and highly virtualized systems.

eXFlash memory-channel storage represents a highly-scalable 
form factor that provides greater performance and granular 
capacity growth. eXFlash DIMMs:

●● ●

Leverage universal DIMM slots, making them ideal for all 

server types including IBM Flex System®

●● ●

Are interoperable with standard DDR3 RDIMMs

●● ●

Support 200 GB to 12.8 TB of memory-channel storage

●● ●

Deliver performance that scales with additional modules 

while keeping latency consistently low. 

eXFlash memory-channel storage contributes to lower licensing 
costs and also helps reduce storage costs. Using internal 
eXFlash storage reduces or eliminates the need for SAN/NAS 
storage and less SAN/NAS hardware means fewer software 
licenses.

IBM FlashCache Storage Accelerator is an advanced intelligent-
caching software that enables IBM eXFlash memory-channel 
storage and hard disk drive storage to transparently work 
together to maximize performance and minimize cost.

Agile design characteristics

Change is inevitable and managing it is a must in order to 
achieve or maintain market leadership. Changes in IT infra-
structure typically drive complexity and cost. Managing  
evolving technology, divergent customer needs and fluctuating 
costs requires an agile approach to platform design. Having 
flexible systems to create fit-for-purpose solutions is essential.

The x3950 X6 is the first server designed and optimized for new eXFlash 
memory-channel storage. It can deliver unmatched storage performance and 
capacity in an x86 server.
