Network architecture

  • This Ready Solution provides end-to-end I/O connectivity. It employs two Emulex LightPulse LPe32000 16 GB FC adapters per host for FC connectivity. One FC port per HBA is connected to a pair of redundant Connectrix DS-6610B FC switches to provide high availability.

    Note: The solution uses Connectrix 16 GB- and 32 GB-capable switches for FC SAN connectivity. Switches are configured to provide redundant A and B fabrics. For the highest availability, Fabric Vision is enabled to monitor the FC SAN health to detect and remediate network congestion that results from devices behaving incorrectly and other network issues.

    Key differentiators of Dell EMC Networking data center switch solutions include:

    • Open networking offerings―More choice with a broad offering of Dell EMC and third-party operating system solutions from partners such as Big Switch Networks, Cumulus Networks, IP Infusion, and Pluribus Networks.
    • Cost-effective port connectivity―Dense port counts in 1RU and 2RU form factors with 24 to 128 ports ranging from 1 G, 10 G, 25 G, 40 G, and 50 G to 100 G.
    • Large scale operations―A leaf-spine 100 G fabric architecture that is massively scalable and easily automated at scale.

    The Dell EMC Networking S5200-ON family, which comprises the S5248, S5296, and S5232 switches, provides multi-line rate (100/25/10 GbE) network connectivity between the compute cluster and the rest of the data center. For more information, see the Dell EMC Networking S5200-ON Series Switches Specification Sheet.

    The Dell EMC S4100-ON family, comprising the S4112, S4124, and S4148 switches, can provide 10/1 GbE connectivity in either SFP(+) configuration or in 10Gbase-T configuration. The 10Gbase-T configuration allows for a 10/1 GbE Cat 6 or 7 connection for data or management. For more information, see the Specification Sheet.

    The Dell EMC S3048-ON switch provides 1 GbE connectivity. For more information, see the Dell EMC Networking S3048-ON Specification Sheet.

    To provide high availability for network connections, multiple network cards in each server are connected to redundant network switches. Two 1 GB NICs connect to a pair of redundant S4100-ON series or S3048-ON switches, while two 10 or 25 GB NICs also connect to redundant S5200F-ON series switches. In accordance with SAP best practices and Dell EMC infrastructure design principles, each application is deployed as a separate workload VLAN. The VLAN is defined in the data center core network―for example, as DEV, QAS, or PRD.
