This section describes the design principles of the Dell EMC Ready Bundle for SAP Landscapes solution with Unity storage and the design of the infrastructure subsystems.
Figure 3 shows the solution architecture.
In a data center environment, consolidating multiple components to reduce the data center footprint and cost is important. Published levels of best SAPS performance enable customers using PowerEdge servers to achieve greater server consolidation ratios because fewer servers are required to achieve the application or database SAPS requirements of an SAP customer.
Server virtualization using VMware vSphere software enables optimal resource utilization. This solution uses server virtualization to make it possible to run multiple operating systems and SAP applications on the same server simultaneously, increasing consolidation, flexibility, and scalability while creating significant cost savings.
The Ready Bundle for SAP Landscapes 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 HA.
Dell EMC Networking S4048-ON switches provide 10 GbE network connectivity between the compute cluster and the rest of the data center, while the Dell EMC S3148P switch provides 1 GbE connectivity.
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 S3148P switches, while two 10 GB NICs also connect to redundant S4048-ON 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 datacenter core network, for example, as DEV, QAS, or PRD.
Unity All Flash storage systems are based on Intel E5-2600 processors. The systems implement an integrated architecture for block, file, and VMware Virtual Volumes (VVols), with concurrent support for native network-attached storage (NAS), iSCSI, and FC protocols. Each system uses dual SPs, full 12 Gb SAS back-end connectivity, and Dell EMC’s patented multicore operating environment to deliver high performance and efficiency. Disk-array enclosures provide additional storage capacity, and online controller upgrades are available for added performance.
The Ready Bundle for SAP Landscapes uses the Unity All Flash array with the following storage profile:
