Australia provides scratch space for the builders (currently via NFS, but iSCSI/AoE/nbd may be used in the future). It is an Intel Core2 Quad system with 8GB RAM, a 1TB disk for the operating system, and four 2TB disks in a RAID-0 array for the scratch space. It has gigabit ethernet interfaces to the builder LAN and SeneNET. == Additional x86_64 systems == Other x86_64 systems in CDOT which are underutilized have been configured as createrepo clients for Koji.
