In an SAP HANA on-premise deployment, SAP HANA runs on dedicated hardware. The on-premise SAP HANA is deployed through the following offerings:
SAP HANA appliance combines SAP HANA software components on proven hardware provided by hardware partners. This approach is valid for Intel-based hardware platforms only. While this approach is simple, it has limitations for hardware flexibility and compliance with existing IT operation processes. Therefore, SAP HANA tailored data center integration is offered as a new option to provide customers with greater flexibility.
SAP HANA tailored data center integration (TDI) provides the customer with more flexibility regarding the hardware components required to run SAP HANA in the data center. Leveraging this approach, customers will have the following benefits:
- Reduce hardware and operational costs by reusing existing hardware components and operation processes
- Mitigate risks and optimize time-to-value by enabling existing IT management processes for SAP HANA implementations
- Have more flexibility in hardware vendor selection by leveraging the existing ecosystem
In short, SAP HANA tailored data center integration helps you to stay within your IT budget, shortens implementation cycles, and allows better consumption of hardware innovations to drive the adoption of SAP HANA.
SAP does not offer any formal certification of a given SAP HANA tailored data center integration infrastructure. Instead, SAP certifies hardware components together with its SAP HANA hardware partners, and requires customers to only use these certified configurations for SAP HANA tailored data center integration.
Use the official SAP HANA Hardware Directory to verify that your compute nodes and storage systems are listed there with the exact same bill of material as the compute servers of certified SAP HANA appliances but without storage.
The installation of SAP HANA needs to be done by a person who possesses a valid SAP-certified technology associate - SAP HANA 2.0 SPSxx (C_HANATEC_xx) or newer.
SAP HANA hardware partners and their employees do not need this certificate. However, companies, or their employees, who are sub-contractors of SAP HANA hardware partners must be certified to perform HANA software installations.
Tailored data center integration can reduce hardware and operations cost by reusing existing hardware components and processes.
Tailored data center integrations offer freedom and flexibility, which also leads to the customer’s increased responsibility for the system, ranging from the installation up to running the landscape.
SAP HANA Tailored Data Center Integration General Requirements
SAP and our SAP HANA hardware and software partners will support SAP HANA tailored data center integration system configurations if they use the following guidelines:
- Use of certified hardware: Only servers listed in the Certified and Supported SAP HANA Hardware directory are supported. These are the same servers as for SAP HANA appliances.
- Use of certified storage: Only storages listed in the enterprise storage tab of the Certified and Supported SAP HANA Hardware directory fulfill the requirements for data throughput and latency, and are supported by SAP.
- Installation performed by an SAP HANA certified person: The person who installs SAP HANA needs to have a valid certification. Current valid C_HANATEC certifications can be found on the SAP Learning Web site.
Tailored Data Center Integration Storage Requirements
SAP HANA Tailored Data Center Integration Enterprise Network Requirements
With the introduction of tailored data center integration with enterprise networks, SAP supports hardware setups, which comply with the prerequisites mentioned below:
Network Segmentation – All networks need to be properly segmented, and can be connected to the same core/backbone switch. SAP recommence to use the following zones setup:
- Client zone - used by the SAP HANA clients like application servers, data sources, and BI clients.
- Internal zone - used for the communication between the SAP HANA worker nodes (inter-node communication).
- Storage zone - used for reading and writing to the enterprise storage, and for writing backups to the backup infrastructure.
The minimum bandwidth requirement for Ethernet is ≥ 10 GbE for the Internal and Storage zone.
The minimum bandwidth requirement when using Fibre Channel for the enterprise storage is ≥ 8 GbF.
Network security and segmentation is a function of the network switch vendor and must be configured according to the specifications of the switch vendor.
Apart from that, no further approval by SAP is required. SAP does not introduce any certification of network components for tailored data center integration setups. Customers should consider involving SAP Active Global Support to perform an SAP HANA Go-Live Check prior to going productive.
