To support the SAP HANA bandwidth requirements, Dell EMC requires 25 GbE network connectivity of the VxFlex nodes.
In addition to the system networks required for vSphere and VxFlex OS, configure the following networks for SAP HANA when the function is used:
Dell EMC recommends creating a new vSphere distributed switch (VDS) for the networks that you require for SAP HANA and assigning additional 2 x 25 GbE network cards as uplinks to this new distributed switch. To meet the performance requirements of the SAP HANA internode network communication, set an MTU size of 9,000 on this distributed switch and in the operating system network settings of the SAP HANA VM for the internode network. For information about configuring networks on a distributed switch, see Dell EMC VxFlex OS Networking Best Practices and Design Considerations.
