Hi, today we ran into a strange problem: When performing a regular Windows 2008r2 update apparently among other things the following was installed: "SUSE - Storage Controller - SUSE Block Driver for Windows" Previously the disk drive was using the Red Hat virtio drivers which worked just fine but after the reboot after the update I just get a blue screen indicating that Windows cannot

I'm still running CentOS 5 with Xen. We recently replaced a virtual host system board with an Intel S1400FP4, so the host went from a 4 core Xeon with 32G RAM to a 6 core Xeon with 48G RAM, max 96G. The drives are SSD. I was recently asked to move an InterBase server from Windows 7 to Windows Server. The database is 30G. I'm speculating that if I put the database on a 35G
