  • More performance by using industry-leading IBM Peripheral Component Interconnect® Express (PCIe) Gen4 slots.
  • Enhanced internal disk configuration options, with up to 14 NVMe adapters (four U.2 NVMe plus up to 10 PCIe add-in cards).
  • Twice as fast back-end I/O enables seamless maximum speed and throughput between on-premises and multiple public cloud infrastructures with high availability (HA).
