Hi, LSISAS1068E is a 2 ports(total 8 PHY) SAS controller with per port can be configured as a 4 PHY SAS wide port,with the usage of arbitrary one port LSISAS1068E can control a SAS expander through a MiniSASx4 to SASx4 cable,we get 4 connections simultaneously.Is it possible for LSISAS1068E to control one SAS expander through two MiniSASx4 to SASx4 cables so we can have 8 connections simultaneously(more bandwidth) if not,why?
