The Advantech SKY-7223D is a 2U short-depth server that is designed largely for 5G telco use cases. Advantech has designed the SKY Series of low-latency edge servers to fit in areas of limited space and extreme environments, when compared to traditional data centers. Like most rugged telco servers, all the I/O access is through the front including storage, PCIe, and networking. The server also has hot-swap elements built for easy, quick service in the field.
