If i understand correctly, you are not planning on adding other ESXi SDSs, what you are looking for, if possible, is 1) adding ESXi SDCs on hosts that are not part of the same/original ScaleIO configuration. Furthermore, these (potentially new ESXi SDCs) hosts are not in the same VCenter (other?). Additionally, you also are looking for, if possible, to 2) add Linux/Windows as SDCs to this same ScaleIO configuration.  Is that correct?  If so, 1) I believe this is possible as long as there is network communication between MDM Cluster and new/future SDC host. You might have to manually install ([URL] page 131) the SDC component in the ESXi host. It is always recommended to use the ScaleIO Plugin, but there might be the chance where it only shows the ESXi hosts associated to the VCenter only.  For your 2) Linux/Windows hosts, yes, you can also install the SDC component alone (preferably also install LIA component). Please, refer to the same guide page 115 for manual installation on physical servers.  Hope this helps!  Andres
I have ScaleIO installed under Vsphere. Members of same Vcenter may see ScaleIO disks. Is it possible to provide some disks to another servers, not connected to the same Vcenter, end even not ESXi servers (like pure Windows or Linux servers)? Thanks
