Modern storage infrastructure for flash, NVMe and FICON

Technology is evolving at an incredible pace, and businesses are demanding more from their IT resources and infrastructure. Rapid adoption of flash storage and the ramp- up of NVMe-based storage unleash advancements in application design that drive new levels of performance and capacity requirements, such as advanced analytics, business intelligence, and data-intensive workloads.

With the integration of new technologies that are accelerating the delivery of data and services, the network will need to evolve to keep pace with innovations in storage and demands of modern applications to maximize the full value of investments in next-generation data center infrastructure. To meet ever-increasing demands for faster, more reliable data access, it is essential for organizations to deploy a modernized infrastructure that reduces latency, increases bandwidth, and ensures continuous availability.

Unprecedented performance is not enough on its own. Powerful analytics and advanced automation capabilities are required to transform current storage networks into an autonomous SAN. This requires a network that is capable of delivering these capabilities to maximize performance, simplify management, and reduce operational costs. Legacy infrastructure was not designed to support the performance requirements of evolving workloads and NVMe-based storage. In fact, an aging network will impede the performance of the on-demand data center. By modernizing the storage network with IBM® Gen 7 Fibre Channel technology, organizations will enable a faster, more intelligent, and more resilient network. This will maximize the performance, productivity, and efficiency of their storage investments and resources, even as they rapidly scale their environments.
