IBM System x3950 X6

With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon
processor E7-4800/8800 v2 product families. This integration helps reduce I/O latency and increase
overall system performance.
Support for up to four graphics processing units (GPUs) and co-processors to maximize computing
power.
Energy-efficient electronic components help lower operational costs, including highly efficient 900 W
AC and 1400 W AC power supplies with 80 PLUS Platinum certification.
Agile system design
The server provides many scalability and flexibility features:
Innovative module "book" design for each of the three subsystems: Compute Books, Storage Book,
and I/O Books. Front and rear access means that you can easily scale the system by adding
components without removing the entire server from the rack.
The modular book design also allows clients to create the configuration that fits their application and
environment needs, which reduces acquisition costs while giving them the flexibility to grow and
modify their configuration later.
The book design also means that subsystem upgrades are simpler, quicker to perform, and have a
lower impact on the rest of the server.
Using 64 GB LRDIMMs, the server supports up to 12 TB of memory.
Up to 32 eXFlash DIMMs are supported for a total of 12.8 TB of low-latency and high-performance
storage.
Up to 32x 1.8-inch eXFlash SSD bays, or up to 16x 2.5-inch bays, provide a flexible and scalable
all-in-one platform to meet your increasing demands.
Offers up to 22 PCIe slots plus two dedicated Mezzanine LOM (ML2) adapter slots. Most slots are
PCIe 3.0 to maximize I/O scalability.
PCIe slots are implemented in I/O Books to maximize modularity. Choose from Half-length I/O Books
or Full-length I/O Books, depending on the adapters that you need to deploy.
Most components are common between the four-socket x3850 X6 and eight-socket x3950 X6, making
for a simple upgrade path with minimal parts on the floor.
Resilient platform
The server provides many features to simplify serviceability and increase system uptime:
Upward Integration Modules for standard hypervisors enable the creation and management of
policies to maintain high availability of virtual machines and concurrent updating of the system
firmware, with no impact on application performance or availability.
Advanced Processor Recovery allows the system to automatically switch access and control of
networking, management, and storage in the event of a processor 1 failure, providing higher
availability and productivity.
Advanced Page Retire proactively protects applications from corrupted pages in memory, which is
crucial for scaling memory to terabytes.
Redundant bit steering, memory mirroring, and memory rank sparing for redundancy in the event of a
non-correctable memory failure.
