Hi Val3ntin,
It is feasible, as it works for me. I have WSE2012 in ESXi 5.1.
1. Link your physical disks to ESXi using the RDM technique described in this blog (http://blog.davidwarburton.net/2010/10/25/rdm-mapping-of-local-sata-storage-for-esxi/)
2. In file "C:\Program Files (x86)\StableBit\Scanner\Service\Scanner.Service.exe.config", change setting "UnsafeDirectIo" to "True" - don't forget to reboot !
Good luck.
