The System x3550 M5 is a cost- and density-balanced 1U, 2-socket business-critical server, offering improved
performance and pay-as-you grow flexibility along with new features that improve server management
capability. New, innovative, energy-smart design with powerful high-performance processors, a large capacity
of high-performing DDR4 memory, and an improved feature set are ideal for business-critical applications and
cloud deployments.
Combining balanced performance and flexibility, the x3550 M5 is a great choice for small and medium
businesses and up to the large enterprise. It can provide outstanding uptime to keep business-critical
applications and cloud deployments running safely. Ease-of-use and comprehensive systems management
tools make it easy to deploy. Outstanding reliability, availability, and serviceability (RAS) and high-efficiency
design improve your business environment and help save operational costs.
Scalability and performance
The x3550 M5 offers numerous features to boost performance, improve scalability, and reduce costs:
Improves productivity by offering superior system performance with up to 18-core processors, up to 45
MB of L3 cache, and up to 9.6 GT/s QPI interconnect links.
Supports up to two processors, 36 cores, and 72 threads to maximize the concurrent execution of
multithreaded applications.
Intelligent and adaptive system performance with energy efficient Intel Turbo Boost Technology allows
CPU cores to run at maximum speeds 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 utilize the hardware for virtualization workloads.
Intel Advanced Vector Extensions 2.0 (AVX 2.0) enable acceleration of enterprise-class workloads,
such as databases, enterprise resource planning, and others.
Up to 2133 MHz memory speeds with two DIMMs per channel running at 2133 MHz to help maximize
system performance.
Up to 1.5 TB of memory capacity with 64 GB Load Reduced DIMMS (LRDIMMs)
12 Gbps serial-attached SCSI (SAS) internal storage connectivity doubles the data transfer rate
compared to 6 Gb SAS solutions to maximize performance of storage I/O-intensive applications.
Flexible and scalable internal storage configurations for up to 46 TB of storage capacity with 3.84 TB
2.5-inch solid-state drives (SSDs) or up to 40 TB with 10 TB 3.5-inch hard disk drives (HDDs) in a dense
1U rack form factor.
The use of SSDs instead of or along with traditional spinning HDDs can significantly improve I/O
performance. An SSD can support a significantly higher number of I/O operations per second (IOPS)
than a typical HDD.
The server has four integrated Gigabit Ethernet ports and optional 10 Gb Ethernet ports with mezzanine
LOM (ML2) adapters.
The server offers up to four PCI Express (PCIe) 3.0 I/O expansion slots in a dense 1U rack form factor.
With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon
processor E5 family. This helps to dramatically reduce I/O latency and increase overall system
performance.
