They will have to combine both MSA LUNs in a OS then Mirror them.

I think I need two HBA if I want to create this kind of RAID5+1 ¿no?<BR /><BR />¿I need to interconect both MSA1000, one to another? ¿Or only conect each MSA1000 to the HBA wich takes the control of the MSA?.<BR /><BR />¿Can I make the RAID1 trought the ACU?<BR /><BR />Thanks all.
