Hey Guys,
i plan to build 3node SW with flat disks and hyper-v on it. Which RAID level i should use on nodes for img files? Is JBOD or RAID0 sufficient/recommended or RAID10 is required?
Thanks

In the case of 3 node configuration, you can surely go with RAID0. You will get an incredible storage performance while redundancy is granted by having 3 mirrored copies of your data provided by StarWind.

Does it make sense to use L2 cache in this scenario? 3x (10x1TB SAS RAID0 ) ?

According to the best practices, you will have to get 1TB SSD space for L2 caching. 10xSAS are already quite fast (moreover in RAID0) and I would say it is not necessary right now but might be considered later when you will need to quickly boost your existing performance.
