IBM System x3550 M4

Performance, flexibility, cost and density - perfectly balanced


Optimised for performance, reliability and virtualisation

The right choice when compromise is not an option, the IBM® System x3550 M4 blends outstanding uptime, performance and input/output (I/O) flexibility with rock-solid reliability for business critical workloads, including cloud computing, virtual desktop, business analytics, HPC and SAP. This compact rack server offers an energy-smart, easy-to-use solution with a pay-as-you-grow design to manage risks. With more computing power per watt, support for the latest Intel® Xeon® E5-2600 v2 series processors and advanced memory support, the x3550 M4 offers balanced performance and density. Ideal for a wide range of business critical applications, including cloud computing and virtualisation. Big things do come in small packages.

Uptime for business-critical applications

With redundant and hot-swap fans, disks and power supplies, the x3550 M4 provides a resilient architecture ideal for business-critical applications. Predictive failure analysis (PFA) and light path diagnostics proactively monitor the system’s sub-components and provide advanced warning on power supplies, fans, voltage regulator modules (VRM), disks, processors and memory. Redundant, hot-swap components make it easy to replace failures without taking your system down. Light path diagnostics displays a visible warning light indicator on a failing component, allowing time for component replacement prior to failure and facilitating high availability (HA).

Select configurations of the x3550 M4 are part of the IBM Express Portfolio designed to meet the needs of small and midsized businesses (SMB). Easy to manage, Express models vary by country.
