While the System x Solution for SAP HANA is a complete, integrated solution, SAP HANA TDI offers you some additional flexibility.

What is SAP HANA TDI? Typically a HANA appliance comes with all necessary components pre-configured and is provided by certified HANA hardware partners, e.g. the Lenovo System Solution for SAP HANA. TDI stands for Tailored Datacenter Integration and targets the usage of certain hardware and infrastructure components already existing in your landscape, instead of the corresponding components delivered with a HANA appliance. This gives you the flexibility to choose a storage component independent of other solution components, supports your existing business processes and can help improve your ROI.

Advantage of Deploying EMC VMAX Storage

There are many certified SAP HANA storage area network (SAN) solutions. If you’re going down the external storage route, EMC VMAX is definitely one to consider.

Just as System x servers hold the record for the highest number of HANA nodes certified by SAP in an appliance scale-out configuration ( 56 nodes), EMC VMAX holds the record for supporting the most HANA nodes (104 nodes) with an eight-engine, single VMAX storage. This shows the scalability that you can expect by deploying System x servers and EMC VMAX storage in an SAP HANA TDI scenario.

When it comes to performance, Lenovo and EMC have established best practices for every configuration involved in a typical SAP HANA TDI scenario. SAP HANA deployment scenarios are also tested and validated by Lenovo and EMC. This information can be found in a technical white paper for Lenovo System x and EMC VMAX for SAP HANA TDI.

To connect to your SAN, the HANA server configuration must include a host bus adapter (HBA) and a Fibre Channel QLogic HBA is an excellent choice. It plays a crucial role in achieving the desired high performance and scalability. 16Gbps Fibre Channel per port maximum throughput for high-bandwidth SAN traffic reduces the backup window of critical databases, such as SAP HANA, that have high data sizes. More than 1.2 million IOPS reduces latency in high transaction-intensive applications such as SAP HANA.
