http://hardforum.com – hello all, i currently have a das built from an m1015 and a chenbro sas expander for 24 disks the m1015 is passed through to an esxi vm. id like to move the server out of the vm and go native. i wonder if i can use the sas expander directly from the os, or do i still need the hba im thinking that driving the sas expander directly would yield more bandwidth. dont know if it's possible. i'd appreciate any advice.
