Yes, cluster managers. Typically Pacemaker, we also support VCS. > Ideally I'd like a system where I can advertise a single IP address in > DNS and have traffic routed to the currently active system but I don't > really understand how all the pieces go together. Read your favorite Pacemaker guide, see below. > Does drbd typically involve NFS? LVM? That really depends what you want.

DRBD Proxy (WAN replication) and the RDMA transport (faster than TCP/IP interconnect) are proprietary. And of course we provide support to customers, depending on your subscription. And there are customer repositories with pre-built packages that follow a slightly different release cycle than the OpenSource versions.
