SAP strictly defines the SAP HANA certified hardware configurations. SAP allows no hardware changes without re-certification.
SAP and NEC defined and certified SAP HANA optimized hardware configurations.
Changes to the available configurations are not allowed due to SAP’s guidelines. This means limited flexibility, while providing fast deployment and high performance.
The NEC SAP HANA appliance comes preinstalled from the factory to the customer, with all necessary OS and HANA information preconfigured, based on customer input. This results in a plug-and-play system.
SAP HANA Tailored Data Center Integration Delivery:
This option gives more flexibility to the customer.
Using a certified NEC HANA appliance as a base system and SAP HANA certified Enterprise Storage (which may be already in place), the customer can reduce hardware and operation cost by re-using existing hardware components and operation processes.
However, the OS and SAP HANA installation and verification needs to be done either by the customer or the integrator, who must have SAP’s certification “E_HANAINS141” to perform the installation.
The customer is responsible for checking his system’s KPIs.
Additionally, SAP Active Global Support offers the HANA Going-Live Check which – among other tests – conducts a data throughput test using the “SAP HANA Hardware Configuration Check Tool”.
SAP system integrators have additional tools for sizing, which can generate a more precise output.
SAP HANA is supported on Redhat Enterprise Linux and SuSE Linux Enterprise Server.
Deploying SAP HANA in a VMware virtual machine on certified hardware is also supported (VMware has a limit of 1TB RAM per VM and SAP only allows a single VM for production systems).
SAP HANA Version
NEC SAP HANA appliances follow SAP’s recommendation to use the SAP HANA revision referenced by / or any newer revision of the same SPS following the SAP HANA Datacenter Service Point for production use cases.
