Your customer wants to implement a software defined storage solution. They require the lowest latency possible in the back-end. Which technology should you recommend to address the customer ' s concern?
For software-defined storage (SDS) environments where back-end latency is the primary concern, the HPE M-series Ethernet switch family is the optimal recommendation. These switches are specifically designed for high-performance storage networking, offering " zero-packet-loss " technology and ultra-low latency that is significantly lower than standard campus or data center Ethernet switches. The M-series (powered by Mellanox technology) is ideal for RDMA over Converged Ethernet (RoCE) workloads, which is the protocol of choice for modern SDS back-ends to minimize CPU overhead and maximize data throughput. While the Aruba CX family is excellent for general-purpose data center fabrics and campus networking, the M-series provides the specialized performance characteristics—such as predictable, sub-microsecond latency—required for mission-critical storage traffic in a software-defined architecture.
