    1. Inspur i48

      A brand-new high-density 4U multi-node modular

      Key Features

      Suitable for large-scale high-density deployments

      8*NS5488M5 compute nodes can be deployed within a 4U rack height. This deployment density is twice as high of that of other rackmount servers. The i48 supports the large-scale computing requirements of high-density data centers. It also enables a uniform deployment of 4* compute and storage

      nodes within a 4U space, which makes it suitable for virtualization and hyper-convergence applications. In addition, it offers a high storage deployment that includes 2* nodes and 72* hard drives within a 4U space. This deployment meets high-density and large-scale storage requirements.

      Optimized port design

      The excellent scalability of the i48 gives it an advantage over other high-density servers. For instance, it supports up to 6* PCIe devices within a 4U8N compute node configuration. The i48 also provides a NUMA-Balanced hardware design for PCIe expansion devices and NVMe devices, which can improve performance by 20% or more. The front-accessible I/O expansion slots further facilitates regular maintenance. prevention design for the system's fans, so as to prevent high-temperature backflows in the channels.

      Effortless cluster implementation and maintenance

      The multi-node and modular design of the i48 allows it to easily achieve the integration of multiple nodes, which can be applied to enable rapid deliveries and rack-mount implementation. The i48 supports CMC redundancy management modules and realizes a unified management of all nodes within the chassis. A 1G network convergence module is configurable to realize a common external network for the entire chassis, thus allowing for the easy management of server clusters.

      Ideal cooling solution

      The i48 has an independent cooling channel for the centralized cooling of server hot spots such as CPU storage, power, and external PCIe devices. The cooling system prevents temperature flow between hot spots.

      The i48 is able to realize the isolation of hot and cold channels for external PCIe devices, which greatly increases cooling efficiency. The server has a backflow
