     1.4 +DRBD is a software-based, shared-nothing, replicated storage solution
     1.5 +mirroring the content of block devices (hard disks, partitions, logical

    1.10 +* in real time. Replication occurs continuously while applications
    1.11 +  modify the data on the device.
    1.12 +* transparently. Applications need not be aware that the data is stored
    1.13 +  on multiple hosts.
    1.14 +* synchronously or asynchronously. With synchronous mirroring,
    1.15 +  applications are notified of write completions after the writes have
    1.16 +  been carried out on all (connected) hosts. With asynchronous mirroring,
    1.17 +  applications are notified of write completions when the writes have
    1.18 +  completed locally, which usually is before they have propagated to the
    1.19 +  other hosts.
