It's been about 3 years total since I've worked with XenServer. Current setup and primary Xenserver node is running 6.0 (old...) early on, i really did not like the strangle-hold citrix had on the features and such, But I know later version are much better. I'm worried to upgrade to 6.1 - should i be? or should it be seemless and not break and Windows VM's ?
Anyways.. really looking into option for a new deployment and future build for current office needs... Already looked at Scale computing. Looks very good and pricing is subjective to the quality of product. nice!
I really like Xen Orchestra and features it presents for XenServer hosts. This was not available tool back when I first implemented xen server. Its really amazing the new tools available to us today....
Was thinking 2 Xen Server hosts with HA-Enabled (is this availble on FREE?) and using Xen Orchestra.
Local storage (SR) sounds nice on the hosts.. not sure if HA-Lizard (DRDB) is supported with Xen Orchestra.
So was thinking of a redundant HA-setup with some high-end Synology 2U units... using NFS storage as SR (rather than iSCSI). Due to storage visibility over network (ability to access actual storage VHD)
Would have a dedicated 10Gbe switch that would have servers connected(2 NIC interfaces - LACP) and also the NAS units.
And then the 2 servers directly connected with patch cable(s) for Xen Orchestra to work.
this is all conceptual....
