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.
The server is Energy Star 2.0 compliant
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 128 GB 3DS RDIMMs, the server supports up to 12 TB of memory.
Up to 16x 1.8-inch SSD bays, or up to eight 2.5-inch bays, provide a flexible and scalable all-in-one
platform to meet your increasing demands.
Offers up to 11 PCIe slots plus a dedicated Mezzanine LOM (ML2) adapter slot. 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.
Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supported operating system.
Intel Trusted Execution Technology provides enhanced security through hardware-based resistance
to malicious software attacks, allowing an application to run in its own isolated space, which is
protected from all other software running on a system.
Redundant Intel Platform Controller Hub (PCH) connections to the processors allow the platform to
maintain access to networking, storage, and server management during a processor failure.
Hot-swap drives support RAID redundancy for data protection and greater system uptime.
Hot-swap I/O Books enabling you to install or replace adapters while the server is still running.
Tool-less lid-less design provides front and rear access for easy upgrades and serviceability. There
