48 IBM System x3850 X6 and x3950 X6 Planning and Implementation Guide
3.1 Product features
The increasing demand for cloud computing and analytics workloads by enterprises to meet
social, mobile, and Big Data requirements drives innovation to find new ways to build
informational systems. Clients are looking for cost-optimized fit-for-purpose IT solutions that
manage large amounts of data, easily scale performance, and provide enterprise class
reliability.
Built on decades of innovation, IBM introduces its sixth generation of Enterprise
X-Architecture technology, IBM X6 servers. IBM X6 servers are designed to be fast, agile,
and resilient:
Fast application performance means immediate access to actionable information.
Agile system design helps to reduce acquisition costs and provide the ability to upgrade
processor and memory technology at each refresh within the same chassis.
Resilient platforms maximize application uptime and promote easy integration in virtual
environments.
IBM X6 servers continue to lead the way as the shift toward mission-critical scalable
databases, business analytics, virtualization, enterprise applications, and cloud applications
accelerates.
3.1.1 Fast application performance
The server offers numerous features to boost performance:
With eXFlash memory-channel storage, the server delivers up to 12.8 TB of ultra-low
latency flash storage using IBM WriteNow technology, ideal for high-performance
applications.
Based on the Intel Xeon processor E7-4800 v2 and E7-8800 v2 product family, x3850 X6
provides the following capabilities:
– x3850 X6 supports up to four E7-4800 v2 processors with 60 cores and 120 threads,
to maximize the concurrent execution of multi-threaded applications.
– x3950 X6 supports four, six, or eight E7-8800 v2 processors with 120 cores and 240
threads.
– x3950 X6 improves productivity by offering superior system performance with 15-core
processors (up to 2.8 GHz core speeds), up to 37.5 MB of L3 cache, and up to three
8 GT/s QPI interconnect links.
It supports memory speeds up to 1600 MHz.
It supports up to 96 DIMM sockets (x3850 X6) or 192 DIMM sockets (x3950 X6), 24
DIMMs per processor.
It supports IBM memory-channel storage and IBM eXFlash DIMMs where solid-state
storage devices are installed in memory DIMM sockets, thereby being directly connected
to the processors and providing the lowest latency values in the industry.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows
CPU cores to run at maximum speeds during peak workloads by temporarily going
beyond processor TDP.
Intel Hyper-Threading Technology boosts performance for multi-threaded applications by
enabling simultaneous multi-threading within each processor core, up to two threads per
core.
