This IBM® Redpaper® publication provides a broad understanding of a new architecture of the IBM Power® E1080 (also known as the Power E1080) server that supports IBM AIX®, IBM i, and selected distributions of Linux operating systems. The objective of this paper is to introduce the Power E1080, the most powerful and scalable server of the IBM Power portfolio, and its offerings and relevant functions:


  • Designed to support up to four system nodes and up to 240 IBM Power10™ processor cores
    The Power E1080 can be initially ordered with a single system node or two system nodes configuration, which provides up to 60 Power10 processor cores with a single node configuration or up to 120 Power10 processor cores with a two system nodes configuration.
    More support for a three or four system nodes configuration is to be added on December 10, 2021, which provides support for up to 240 Power10 processor cores with a full combined four system nodes server.
  • Designed to supports up to 64 TB memory
    The Power E1080 can be initially ordered with the total memory RAM capacity up to 8 TB.
    More support is to be added on December 10, 2021 to support up to 64 TB in a full combined four system nodes server.
  • Designed to support up to 32 Peripheral Component Interconnect® (PCIe) Gen 5 slots in a full combined four system nodes server and up to 192 PCIe Gen 3 slots with expansion I/O drawers
    The Power E1080 supports initially a maximum of two system nodes; therefore, up to 16 PCIe Gen 5 slots, and up to 96 PCIe Gen 3 slots with expansion I/O drawer.
    More support is to be added on December 10, 2021, to support up to 192 PCIe Gen 3 slots with expansion I/O drawers.
  • Up to over 4,000 directly attached serial-attached SCSI (SAS) disks or solid-state drives (SSDs)
  • Up to 1,000 virtual machines (VMs) with logical partitions (LPARs) per system
  • System control unit, providing redundant system master Flexible Service Processor (FSP)
  • Supports IBM Power System Private Cloud Solution with Dynamic Capacity

This publication is for professionals who want to acquire a better understanding of Power servers. The intended audience includes the following roles:


  • Customers
  • Sales and marketing professionals
  • Technical support professionals
  • IBM Business Partners
  • Independent software vendors (ISVs)

This paper does not replace the current marketing materials and configuration tools. It is intended as an extra source of information that, together with existing sources, can be used to enhance your knowledge of IBM server solutions.
