Hello, we just bought DELL ME4024 with dual controller and i have a quastion. We have 2 Dell servers connected to our new ME4024 via SAS cables (one cable to each ME4024 controller). 

Server 1 ---> ME4024 controller A, 0 port

Server 1 ---> ME4024 controller B, 0 port

Server 2 ---> ME4024 controller A, 1 port

Server 2 ---> ME4024 controller B, 1 port

I created 2 disk-groups RAID 10, 4x900GB SAS disk each (some reason, there was no possibility to create just 1 group with 8 disks, lol). Configured Pool, Volume, Initiators, Hosts and Host group, then configured ESXi and SAS Multipathing on our ESXi servers. Now it looks like this: https://ibb.co/y53Lqpr
So, how can i configure the storage reservation now? If storage A faults, how storage B will work?

I want somekind of RAID1 between storages A and B, if 1 fails the 2 works. Is it possible?
