Highly composable blade architecture

  • Features



    • Increased density, improved management, and energy efficiency reduces operating costs
    • Unsurpassed four-socket memory capacity, featuring up to 6TB† TruDDR4 memory, enabling more VDI users or VMs per node, larger in-memory databases, etc.
    • Deploy new capabilities for virtualization, performance, and industry-leading networking flexibility
    • Ideal platform for large databases, server consolidation, client virtualization, and users needing more computing power than 2P and older 4P blades can offer

    † 3TB TB at GA; 128GB DIMMs available in the near future. Available prior to GA via special bid.

    Infrastructure made simple

    The Lenovo Flex System Enterprise Chassis now supports two new blades, incorporating powerful Intel® Xeon® processor Scalable family CPUs: the four-processor Lenovo ThinkSystem SN850 and the two-processor Lenovo ThinkSystem SN550. The chassis was engineered to support high-speed networking and multiple generations of Intel Xeon processors.

    SN850 offers massively increased memory capacity and bandwidth, more processor cores, faster and larger storage capacity, plus enhanced RAS and security features**. As a result, SN850’s four-CPU, 48 DIMM-slot design is powerful enough for even your most demanding memory-intensive workloads. Examples include in-memory databases, batch and real-time analytics, virtualization, large traditional databases, distributed computing, or consolidating multiple past generation servers onto a single blade. In addition, SN850 is also compatible with your current Flex System Enterprise chassis, protecting your investment in chassis infrastructure.

    ** Compared to the prior-generation Lenovo Flex System x440.
