| + | The testbed sports a mixture of older and newer hardware. The flagships are the two blades blade13 and blade14 in Cabinet 08. They have a Fibre Channel interface to the Compellent, on which they share a 1024 GiB multipath block device. | ||

| + | Two somewhat older machines, arrone and aulnes, have no Fibre Channel interface but they share an iSCSI target on storage.testbed, which is a FreeNAS box with about 2 TB of data. | ||

| + | These four machines all run [http://www.debian.org/releases/stable/ Debian squeeze] with [http://www.linux-kvm.org/page/Main_Page KVM] for virtualization, managed by [http://libvirt.org/ libvirt]. | ||

| + | These hosts cannot be accessed directly; they live in a LAN with no inbound connectivity. The management host '''bleek.nikhef.nl''' is the entry point to the entire testbed. It takes care of network address translation (NAT) of the 10.198.0.0/16 range used inside the testbed, resolving hostnames and handing out ip addresses (with dnsmasq), serving home directories, and serving VM installation details such as kickstart files (Red Hat/Fedora) and preseed configuratios (Debian). | ||

| + | There are some more machines with an earlier setup using Xen on CentOS 5, but these will be phased out and reinstalled. | ||
