The solution stack uses either Owhile still supporting standard management interfaces or KVM as the virtualization platform, LVM for disk and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, management, and optionally DRBD for disk replication LACP, 802.1ag). In addition, it is designed to support across physical hosts. Ganeti is essentially a wrapper distribution across multiple physical servers similar to around existing which makes it convenient VMware’s vNetwork distributed vswitch or Cisco’s Nexus for system administrators to set up a cluster.
