My lab consists of pretty basic hardware, but still, it's interesting to see performance benefits using different solutions. So I decided to see if there were any performance differences between using 2008 R2 NFS and Starwind iSCSI as storage for VMs. So I had this XenServer 5.6 FP1 running on a HP ProLiant ML115 G5. Then I had a ML115 G1 model with several disks in it, I decided to do all tests on a basic SATA 500 GB disk [...]

Do be able to move VMs between XenServers without shutting them down you need to create a pool You could do this via GUI: But I ran into problems since I have one ML115 G1 and one G5 with different CPUs. The GUI gave me the error "This server's hardware is incompatible with the master's": Run cat /proc/cpuinfo to get details and see if the CPUs differ and you can force them even though they differ. Just be careful when [...]

In part 1, we installed StarWind iSCSI and added a simple virtual disk for a VM. In my lab I have a server (NAS1) with a 750 GB C: drive and the server is iSCSI-enabled using Starwind. From XenServer I want to install 20 VMs (Windows 2008 R2) on it, each with a 72 GB system disk. The installed OS will not take up more than 12 GB, so each VM will have 60 GB free space for future use. [...]
