 ## Circuit SKUs
 
-ExpressRoute Direct supports massive data ingestion scenarios into Azure storage and other big data services. ExpressRoute circuits on 100-Gbps ExpressRoute Direct now also support **40 Gbps** and **100 Gbps** circuit SKUs. The physical port pairs are **100 Gbps or 10 Gbps** only and can have multiple virtual circuits. Circuit sizes:

-> You are able to provision logical ExpressRoute circuits on top of your chosen ExpressRoute Direct resource (10G/100G) up to the Subscribed Bandwidth (20G/200G). E.g. You can provision two 10G ExpressRoute circuits within a single 10G ExpressRoute Direct resource (port pair). Today you must use Azure CLI or PowerShell when configuring circuits that over-subscribe the ExpressRoute Direct resource.

 ExpressRoute Direct supports both QinQ and Dot1Q VLAN tagging.
 
-* **QinQ VLAN Tagging** allows for isolated routing domains on a per ExpressRoute circuit basis. Azure dynamically gives an S-Tag at circuit creation and cannot be changed. Each peering on the circuit (Private and Microsoft) will use a unique C-Tag as the VLAN. The C-Tag isn't required to be unique across circuits on the ExpressRoute Direct ports.
