With Revision 4 of HANA Large Instance stamps, the network latency between Azure VMs that are deployed in proximity to the HANA Large Instance stamp, is experienced to meet the average or better than average classification as documented in [SAP Note #1100926 - FAQ: Network performance](https://launchpad.support.sap.com/#/notes/1100926/E) if Azure ExpressRoute Fast Path is configured (see below). In order to deploy Azure VMs in close proximity to HANA Large Instance units of Revision 4, you need to leverage [Azure Proximity Placement Groups](https://docs.microsoft.com/azure/virtual-machines/linux/co-location). The way how proximity placement groups can be used to locate the SAP application layer in the same Azure datacenter as Revision 4 hosted HANA Large Instance units is described in [Azure Proximity Placement Groups for optimal network latency with SAP applications](sap-proximity-placement-scenarios.md).

To provide deterministic network latency between VMs and HANA Large Instance, the choice of the ExpressRoute gateway SKU is essential. Unlike the traffic patterns between on-premises and VMs, the traffic pattern between VMs and HANA Large Instance can develop small but high bursts of requests and data volumes to be transmitted. To handle such bursts well, we highly recommend the use of the UltraPerformance gateway SKU. For the Type II class of HANA Large Instance SKUs, the use of the UltraPerformance gateway SKU as a ExpressRotue gateway is mandatory.

> Given the overall network traffic between the SAP application and database layers, only the HighPerformance or UltraPerformance gateway SKUs for virtual networks are supported for connecting to SAP HANA on Azure (Large Instances). For HANA Large Instance Type II SKUs, only the UltraPerformance gateway SKU is supported as a ExpressRoute gateway. Exceptions apply when using ExpressRoute Fast Path (see below)
