Silverpeak SD-WAN

Greetings all

Hope you are doing well

Am looking for experts to assist me with some queries about Silverpeak : )

I am working with a partner to evaluate some RFP points and am concerned about Silverpeak as I did not have much answers in their datasheets:

Segmentation : I know Silverpeak were deploying what so called BIOs for segmentation purposes which was limited to 7 BIOs. As for now , I can see that they support VRF in their new released data sheets , how many VRFs do they actually support?

High Availability : The end customer is looking for an active/active branch architecture , what I have found about Silverpeak is what so called HA cluster , is this the same as a real active/active ?

Throughput : The end customer is having requirements for 15 - 20 Gbps of traffic , per the Silverpeak datasheet XL supports 2 - 10 Gbps , does that means they will not be able to comply here?!

Scalability : How can I verify that they can scale up to for example 1000 sites? Nothing is mention in regard.

IPv6 : IPv6 is required by the end customer , only basic IPv6 features are supported. Am I missing something ?

Appreciated.
