Modern storage infrastructure built for flash, NVMe and FICON
With the growing adoption of flash and the ramp-up of NVMe- based storage, organizations will move more data through a SAN than ever before, requiring an increase in I/O capacity to keep up with ever-increasing demand. Coupled with rising complexity and higher expectations for availability, organizations need a network that is capable of maximizing performance while simplifying and automating management. These capabilities are required to help enterprises increase the productivity and efficiency of their storage investments and resources.
To meet these requirements, the network needs to evolve. An IBM® b-type Fibre Channel infrastructure unleashes the performance of NVMe workloads with reduced latency and increased bandwidth. In addition, this infrastructure lays the foundation for an autonomous SAN by combining powerful analytics and advanced automation capabilities to maximize performance and ensure reliability. With autonomous SAN technology, organizations can realize a self-learning, self- optimizing, and self-healing storage network.
The IBM® Storage Networking SAN64B-7, with unmatched 64Gb/s performance and industry-leading port density, provides a building block that supports data growth, demanding workloads, and data-center consolidation. With a 50% latency reduction compared to the previous generation, the SAN64B-7 Switch enables the maximum performance of traditional Fibre Channel, NVMe, and FICON storage.
The SAN64B-7 Switch utilizes built-in analytics to optimize performance and eliminate disruptions. This Gen 7 switch collects comprehensive telemetry data across the fabric to enable advanced analytics. To visualize the data, IBM SANnav™ Management Portal enables organizations to easily understand the health and performance of the SAN. By leveraging automation, SAN admins gain the ability to automate repetitive tasks to save time and mitigate disruptions with limited expertise. The SAN64B-7 simplifies deployment, configuration, and management of SAN resources with a collection of easy-to-use tools.
To further simplify operations and increase visibility, the SAN64B-7 includes Fabric Vision® technology to monitor and analyze the SAN. This technology provides visibility and insight to quickly identify problems and achieve critical service-level agreements (SLAs). To streamline management workflows, organizations can leverage IBM® SANnav Management Portal to accelerate the deployment of new applications, switches, servers, and storage. Furthermore, a modernized graphical user interface (GUI) improves operational efficiencies with visual dashboards for instant visibility and faster troubleshooting.
