High density, highly scalable. Lenovo DB620S fibre Channel SAN switches are designed to provide high flexibility, scalability, and ease of use. Enterprises can scale from 24 ports to 64 ports in an efficient 1U package, including 48 SFP and 4 Q-Flex ports. In addition, the simplified deployment process and click-and-click user interface make Lenovo DB620S very easy to use. With DB620S, companies can have both: high-performance access to industry-leading storage technologies and "pay-as-you-go" scalability that supports evolving storage environments.Greatly improve performance. Faced with unpredictable virtualized workloads and a growing flash storage environment, enterprises must ensure that the network does not become a bottleneck. By combining market-leading throughput and low latency on 32Gbps and 128Gbps links, Lenovo DB620S can deliver higher performance to support growing dynamic workloads. With sixth-generation ASIC technology that can switch 566 million frames per second, Lenovo DB620S switches can break application performance barriers and take advantage of 100 million input / output operations per second (IOPS) to meet the needs of flash storage workloads. At the same time, the inter-port latency can be reduced to 900ns by using cut-through switching at speeds up to 32Gbps. With 48 SFP ports and 4 Q-Flex ports (providing 4 32Gbps connections each), Lenovo DB620S can be expanded to 64 device ports, achieving the total throughput of 2Tbps. In addition, each Q-Flex port can support 128Gbps's parallel fibre Channel (FC) to provide device or Inter Switch-Link (ISL) connectivity, allowing administrators to consolidate and simplify cabling infrastructure. By consolidating eight ISL into a single frame-based 256Gbps bundled link, administrators can achieve optimized bandwidth utilization, excellent availability, and load balancing. This can be achieved through 8 32Gbps SFP ports or 2 4 × 32Gbps QSFP ports. In addition, switching-based dynamic path selection (DPS) optimizes network-wide architecture-wide performance and achieves load balancing by automatically routing data to the most efficient available paths in the network architecture. This complements ISL Trunking (ISL Link Bundle) to provide more efficient load balancing in specific configurations.
Simplify management. Designed to provide flexibility and value, this enterprise-class switch provides "pay-as-you-go (pay-as-you-grow)" scalability through on-demand port extension (PoD) capabilities. Businesses can scale from 24 to 64 ports quickly, easily, and cost-effectively with a combination of 12-port SFP PoD and 16-port Q-Flex PoD licenses. Each of the 48 SFP ports can support FC speeds of 4, 8, 10, 16 and 32Gbps, while four Q-Flex ports can support 4 × 32Gbps or 128Gbps FC speeds, respectively. In addition, the Q-Flex port is designed to support QSFP optical modules, enabling cable consolidation at 4:1 (four cables into one on each port).
Gain total control and insight. Lenovo DB620S with sixth-generation FC technology and integrated network sensors can help enterprises achieve more effective control and comprehensive insight, quickly identify the root causes of problems in the storage layer, shorten troubleshooting time, and ensure that critical service level agreement (SLA) requirements are met. The iCandroo Insight function can smoothly collect IZP O statistics. You can then use this data to configure thresholds and alerts in a policy-based intuitive monitoring and warning suite. In-band device latency and IOPS monitoring can detect storage performance degradation and help administrators proactively optimize performance and availability to ensure high performance.
