We are currently running VMWare ESXi, with 1 Windows 2008 R2 Standard instance, 1 Windows 7 instance and 2 Linux instances.
So, recently I wanted to upgrade my server, because there were a lot of things happened. I couldn't find Intel 1GB multiport adapter, so I get Dlink's adapter, but it was not supported by VMWare. Another issue is that our hardware NAS is extremely slow, and their technical support is dud at best. 20MB/s of RAID5 with NIC teaming and only iSCSI really can't say much in term of performance. So I have encountered Starwind VirtualSAN which can only run only under Windows. Therefore I plan to migrate my VMWare into HyperV.
We have only 1 Windows 2008 R2 Standard license available. But as I read on Microsoft site, Windows 2008 R2 Standard is eligible for 1 VM and 1 host. This Windows 2008 R2 is responsible for Citrix Remote Desktop.
I have successfully performed the migration, but I have a few question remains before performing the live migration.
- Since I can run 2 Windows 2008 R2 Standard total (host + VM), should I run Windows 2008 R2 Standard on top of Windows 2008 R2 Standard host, or is it better with Windows 2012 R2 HyperV host? Is there any new features in 2012 R2 I should know about than 2008 R2 counterpart?
- VMWare's Ubuntu support has been excellent, and it is very fast. How about HyperV performance? Anyone ever tried to compare Ubuntu server on HyperV and on VMWare?
- Is it better to let them VMs access iSCSI from their host, or just allocate fixed VHD to them? i.e, 100GB for VHD + 2TB of iSCSI, or just put 100GB VHD and 2TB VHD? The iSCSI will be cached by about 16GB cache RAM on the host. I really have to install Starwind on HyperV host, since I have another server which currently accessing iSCSI too.
Thank you for helping
