Sounds good. For this installation, you'll want to first setup the storage network within XenServer as a separate management network. I recommend also using an MTU of 9000 (precise value will depend on the switches, and don't forget to test that packets aren't fragmenting or you'll have horrible performance/won't work). If you're plan is to multipath (as opposed to LACP bond), then also set that up in XenServer directly, but do be aware that CloudStack won't natively work with multipath. That's the PreSetup you might have seen, and is also how I've had to deal with things in my environment even without multipath, so currently my best practice.
In CloudStack, the concept of a storage network is one where all the elements related to storage are on their own dedicated network. For how I've had to set things up, this wasn't always the case so I avoided the CloudStack storage network concept and chose to manage my storage directly. When you define primary storage in CloudStack, you can have CloudStack directly manage it (iSCSI, NFS and Local for XenServer), or with XenServer you can tell CloudStack that it just exists. That's what I've typically had to do for a variety of reasons related to my local environment. In that model, you precreate your SR and give it a name, then when you define the primary storage for a cluster, you supply that name and choose PreSetup as the storage type. One caveat is that the name needs to be unique within the Zone, so if you attempt to add a new primary storage and it fails, check the name for duplicates. -tim On Mon, Jun 23, 2014 at 1:25 PM, Ian Marshall <i...@itlhosting.co.uk> wrote: > Hi Tim > > I was hoping to utilise iscsi.
