This solution provides end-to-end I/O connectivity. It employs two Emulex LPe32000-M2 32 GB Dual-Port PCIE 3.0 Fibre Channel HBA adapters per host. 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 Networking data center switch solutions include:
The Dell Networking S5200-ON family, comprising 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 Dell PowerSwitch S Series 10/25/40/50/100/200/400GbE Switches.
The Dell S4100-ON family, consisting of 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 Dell PowerSwitch S Series 10GbE Switches.
The Dell S3048-ON switch provides 1 GbE connectivity. For more information, see PowerSwitch S-Series 1 GbE Switches.
To provide HA 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 GB or 25 GB NICs also connect to redundant S5200F-ON series switches. In accordance with SAP best practices and Dell 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.
