The Flex System x222 Compute Node is a high-density offering that is designed to maximize the
computing power that is available in the data center. With a balance between cost and system features,
the x222 is an ideal platform for dense workloads, such as virtualization. This section describes the key
features of the x222.
Scalability and performance
The x222 offers numerous features to boost performance, improve scalability, and reduce costs:
Two independent servers in one mechanical package to maximize computing capacity.
Powered by the Intel Xeon processor E5-2400 product family to improve productivity by offering
affordable dual-socket system performance with eight-core processors with up to 2.3 GHz core
speeds, up to 20 MB of L3 cache, and one QPI interconnect link of up to 8 GTps.
Up to two processors in each server, 16 cores total, and 32 threads maximize the concurrent
execution of multithreaded applications.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processor
cores to run at maximum speed during peak workloads by temporarily going beyond processor
Thermal Design Power (TDP).
Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling
simultaneous multithreading within each processor core, up to two threads per core.
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating
system vendors to better use the hardware for virtualization workloads.
Intel Advanced Vector Extensions (AVT) improve floating-point performance for compute-intensive
technical and scientific applications compared to Intel Xeon 5600 series processors.
There are 12 DIMM sockets in each server, which support low profile (LP) RDIMMs and LRDIMMs,
with a total capacity of up 384 GB using 32 GB LRDIMMs.
Supports memory speeds of up to 1600 MHz to maximize memory performance.
Support for 2.5-inch and 1.8-inch solid-state drives (SSDs) to maximize I/O operations per second
(IOPS), which significantly improves application performance.
The theoretical maximum memory bandwidth of the Intel Xeon processor E5-2400 product family is
38.4 GBps, which is 20% more than in the previous generation of Intel Xeon 5600 processors.
The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum
bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the previous
generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding)
With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon
processor E5 family. This integration reduces I/O latency and increases overall system performance.
