Looking at latest recommendations -
http://www.oracle.com/technetwork/se...es-2334546.pdf - specifically regarding domain roles.
At the moment, we just have a physical host, primary control domain and then guest ldoms. We then export things like vdisks,vnet etc from control domain to ldom. We don't have any additional service/IO domain.
Should we? Document doesn't really make it clear where and when you need to do this.
Some of our hosts are solaris 10, some 11.2, some 11.3. Ldoms can be anything from solaris 8 upwards.
Hardware wise, we've got some T3s, some T4s, but mainly T5s. And one new S7.
