    Description

    The Brocade DCX 8510-8 is a premier 14 U modular backbone delivering Gen 5 Fibre Channel performance for mission-critical storage networks. Featuring eight vertical blade slots, it supports up to 512 ports of 16 Gbps Fibre Channel, enabling an aggregate chassis bandwidth of 8.2 Tbps and frame rates exceeding 420 million fps (docs.broadcom.com).

    Built for non-stop operations, the DCX 8510-8 leverages industry-proven reliability with Hot-swappable power and cooling modules and achieves better than 99.999% uptime in the most demanding data centers. Its support for multiple protocols—2/4/8/10/16 Gbps FC, FICON®, and FCIP—provides maximum flexibility for heterogeneous SAN environments.

    Designed to simplify scale-out SAN architectures, the DCX 8510-8 integrates UltraScale inter-chassis links (ICLs) to connect up to 10 chassis over optical spans of up to 100 meters, reducing cabling by 75% and freeing up to 25% of ports for additional server and storage traffic.

    Compatibility

    The DCX 8510-8 backbone integrates seamlessly with existing Brocade fabrics, supporting both fixed-port and director-class switches. It interoperates with major storage arrays (EMC, NetApp, HPE) and virtualization platforms (VMware, Hyper-V). The backbone’s FICON support enables direct connectivity to IBM Z mainframes, while FCIP facilitates secure SAN extension over IP networks. UltraScale ICLs allow consolidation of multiple chassis for unified SAN fabrics across data halls.

    Usage Scenarios

    Virtualization & Private Cloud:
    Deploy the DCX 8510-8 to build high-density SAN fabrics for VMware vSphere and Microsoft Hyper-V clusters. Its low-latency, high-throughput switching accelerates VM migrations, storage vMotion, and containerized workloads, ensuring optimal performance and consolidation.

    All-Flash & Hybrid Storage:
    Leverage Gen 5 Fibre Channel to maximize the performance of all-flash arrays and hybrid storage platforms. The backbone’s high port density and bandwidth enable flash farms with minimal oversubscription, reducing contention in high-IOPS environments.

    Mainframe & Disaster Recovery:
    Connect IBM Z environments via FICON blades for mainframe I/O, while FCIP links provide encrypted, compressed replication to remote sites. The DCX 8510-8’s carrier-class reliability and Fabric Vision analytics ensure continuous data protection and SLA adherence.
