Summary
Using SAP HANA in TDI deployments with Dell metro node enables customers to lower their hardware and operational costs because storage and network components can be shared, reducing risk, improving availability and performance, and increasing hardware vendor choice.SAP has certified the metro node appliance for use in SAP HANA installations on both production and nonproduction systems and on scale-up and scale-out systems.
Metro node can combine data that is on heterogeneous certified storage arrays to create dynamic, distributed, highly available data centers. The metro node appliance represents the next-generation architecture of VPLEX for data mobility and continuous availability.
Findings
Our tests with SAP HANA on the metro node appliance showed that:
- The SAP HANA-HWC-ES 1.1 certification scenario makes higher disk configuration demands.
- SAP HANA production installations on metro node meet the SAP HANA storage performance KPIs when the configuration and scalability rules that are described in this guide are followed.
- SAP HANA production installations on metro node require SSDs for the SAP HANA persistence.
- Using SSDs for the SAP HANA persistence provides significant benefits, including:
- SAP HANA startup and host autofailover times are reduced
- SAP HANA backup times are reduced
- It is not necessary to consider spindle count because initial array and disk configuration can be performed based on capacity
