I have RX100 S6 with SATA too, What about adding some HW raid card? Its is possible add it and connect to SATAs drive and work on ESXi 5?
Ok I answer to my selv. If you want to use raid with RX100 S6 and you have only onBoard LSI raid you MUST buy:
1. FUJITSU RAID Ctrl 6G SAS 0/1/10 (D2607) - pro TX140S1, TX150S7, TX200S6-7, TX300S6, RX100S6, RX100S7, RX200S6-7, RX300S6
2. FUJITSU RAID OPTIONS consisting of SAS Cable and bracket kit pro RX100S6
Then you can work with ESXI5 on RAID.
