Re: HP exam "Implementing HP StorageWorks EVA"
when you create a snapshot a vdisk family is created. The iSCSI initiator is located on the server, to which a vdisks is presented by iSCSI. The storage system is the iSCSI target.

Re: HP exam "Implementing HP StorageWorks EVA"
AFAIK is a Vdisk famaliy created, when a Vdisks has at least one snap. The snap belongs to the Vdisks and can't exist without a parent Vdisk.
The iSCSI Initiator is located above the NIC driver. I think it's the iSCSI driver in you picture.

Re: HP exam "Implementing HP StorageWorks EVA"
The term 'family' and the "ACTIVE" object are still present in the output of the Storage System Scripting Utility (SSSU), though.
Indeed, in the picture "iSCSI driver" refers to a "Software iSCSI initiator", but you could enhance the right adapter and write "SCSI or iSCSI or FC HBA". In that case, "iSCSI HBA" is a "Hardware iSCSI initiator" and the "iSCSI driver" function is part of that element.
