Dell PowerEdge R940xa CTO Rack Server Product Description

Rapidly transform data insights into business outcomes with the PowerEdge R940xa. The R940xa accelerates applications with powerful four-socket performance in a scalable 4U design.

Accelerate application performance

The PowerEdge R940xa drives GPU database acceleration to deliver real-time decisions for compute-intensive applications. By combining four CPUs with four GPUs, the R940xa delivers consistent high performance for demanding applications. The R940xa allows you to dynamically scale capacity and performance as your business-critical workloads evolve including:

  • Maximizing performance with 2nd Generation Intel Xeon Scalable processors, up to 112 cores.
  • Choosing up to 4 double-width GPUs or up to 4 double-width or 8 single-width FPGAs for application acceleration.
  • Supporting large data sets with up to 48 DIMMs (24 of which can be DCPMMs) and up to 15.36TB of memory.
  • Scaling on-premise capacity with up to 32 x. 2.5” HDDs/SSDs and up to 4 direct-attached NVMe drives.
  • Expanding quickly with up to 12 PCIe slots for external device connections.

Streamline operations with Dell EMC OpenManage

The Dell EMC OpenManage portfolio helps simplify IT operations across your data center, delivering intelligent, automated management of routine tasks. Combined with unique agent-free management capabilities, the R940xa is simply managed, freeing up time for high profile projects.

  • Utilize a variety of OpenManage integrations and connections to take advantage of your existing IT management platform.
  • Take advantage of QuickSync 2 capabilities and gain access to your servers easily through your phone or tablet.

    Rapidly transform data insights into business outcomes

    The PowerEdge R940xa accelerates applications to deliver real-time decisions. The R940xa combines four CPUs with four GPUs in a powerful 1:1 ratio to drive database acceleration. With up to 6TB of memory and four-socket performance, the R940xa delivers consistent and fast response times. Scale on-premises capacity to offset rising cloud fees and security risks. 

    Ideal workloads:

    • Compute intensive applications
    • Machine learning and artificial intelligence
    • GPU database acceleration

    Dynamically scale resources as your workloads evolve

    The 4U R940xa allows you to flexibly adapt to changing business demands. Large internal storage gives you the space to grow as your databases increase in complexity and size.

    • Increase performance with up to four 2nd Generation Intel Xeon Scalable processors and up to 112 processing cores
    • Choose up to four double-width GPUs or up to four double-width or eight single-width FPGAs to accelerate workloads
    • Address large data sets with up to 48 DIMMs (24 of which can be DCPMMs) and up to 15.36TB of memory
    • Scale capacity with up to 32 2.5” HDDs/SSDs, including up to four NVME drives
    • Expand quickly with up to 12 PCIe slots for external connections
