PowerEdge R710 and PowerVault MD1000 Emm

I was sort of thrust into our office server setup. Boss has PowerEdge R710 Servers, and a PowerVault MD1000, and asked me to hook-up. But I read somewhere that MD1000 starts support with PowerEdge 840!? So I CANNOT hook-up the R710s to this power vault??

Does anyone know if this is a correct assumption??
