comment Incredibly slow snapshot removal
The 10Mbit gibt hint is still nagging me. Is your storage connected to such a slow network and is that network connected to the vCenter or ESXi host, too?

@AD7six Probably true. The canonical Q points it out pretty well.

@AD7six After reading the comments I know enough. And ECC is a must have.

comment Can I stripe 2 volumes on the operating system drive?
@hyppy You are wrong. Measure the values with a current hardware RAID controller.

comment Can I stripe 2 volumes on the operating system drive?
@Chopper3 agreed with 6 disks or more. Up to 8 disks I prefer R6, over 10 disks can give R10 a performance bonus (if the controller is not the bottleneck), but has less reduncy than R6. So generally our currenct policy is R6. But not for this case here.

comment How can I best secure NFS between an Xen host on Debian and VMs?
@Nysepho I don't know if NFSv4 will be fast enough for your needs. iSCSI could be faster. There you have to activate CHAP to make the connection initiation secure. Do you need encrypted data on the line, too?

comment Preventing theft of data on remotely deployed servers exposed to physical access
@BlueCompute The question can arise in a professional environment as well, so it should stay here.

Another way to access a server is by exploiting a weakness in drivers loaded through hot-plugging. So you should prevent access to all external ports (especially USB), too AND disable hot-plugging and/or unneeded drivers where possible.
