ThinkSystem DB400D and DB800D FC DirectorsDatasheet
Network innovation for the virtualized, all-flash data center
Purpose-Built for Enterprise Deployments
Designed to meet relentless growth and mission-critical application demands, Lenovo Fibre Channel (FC) Directors are the right platform for large enterprise environments that require increased capacity, greater throughput and higher levels of resiliency. The Lenovo FC Director is available in two modular form factors: 14U Lenovo DB800D with eight vertical blade slots for large enterprise networks and the 8U Lenovo DB400D with four horizontal blade slots for midsize networks.
This modular chassis design increases business agility with seamless storage connectivity and flexible deployment offerings. Each blade slot can be populated with a choice of optional blades. For device connectivity, there are two Generation 6 offerings; the FC32-48-port blade provides 48 32Gbps FC ports, while the FC32-64-port blade provides 16 QSFP+ ports that can support up to 64 32Gbps FC or 10/24/40/100Gb FCoE connections.
To support disaster recovery and data-protection storage solutions over long distances, the SX6 FC-IP SAN Extension Blade provides 16 32Gbps FC ports, 16 1/10 Gigabit Ethernet (GbE) ports, and two 40GbE ports for FC and IP replication traffic.
Lenovo FC Directors feature industry-leading Generation 6 FC that increases performance for demanding workloads across 32Gbps line-speed links and up to 20.4Tbps of chassis bandwidth to address next-generation I/O- and bandwidth-intensive applications. Generation 6 FC technology provides up to 566 million frames switched per second per ASIC, unlocking the full capability of flash storage. This breakthrough performance speeds up data-intensive application response times, allows more transactions in less time, and enables improved service level agreements (SLAs).
Simplified, Scale-out Network Design
UltraScale chassis connectivity leverages optical Inter-Chassis Links (ICLs), which provide 128Gbps bandwidth through a QSFP link. These links can provide support up to 2km and connect up to 12 Directors, enabling flatter, faster and simpler fabrics that increase consolidation while reducing network complexity and costs. These high-density chassis topologies reduce inter-switch cabling by 75% and free up to 25% of ports for servers and storage. This maximizes overall port density within the smallest amount of rack space while freeing up front-facing device ports for server and storage connectivity.
Adapting to Next-Generation Storage
To realize the full benefits of flash, organizations will need to transition their high-performance, latency-sensitive workloads to flash-based storage with NVMe. The simplicity and efficiency of NVMe over FC enable significant performance gains for flash storage. For investment protection, Lenovo FC Directors offer three generations of backward-compatibility support for connectivity to 4, 8 and 16Gbps FC products. And, the Directors support future FC generations as a Generation 7-ready storage networking platform. The Lenovo FC Director also allows for current Generation 6 and future generation switch blade modules to be added within the chassis.
