| Hans-G?nter@24501 | 1 DRBD is a software-based, shared-nothing, replicated storage solution |
| Hans-G?nter@24501 | 2 mirroring the content of block devices (hard disks, partitions, logical |
| Hans-G?nter@24501 | 3 volumes etc.) between hosts. |
| Hans-G?nter@24501 | 4 |
| Hans-G?nter@24501 | 5 DRBD mirrors data |
| Hans-G?nter@24501 | 6 |
| Hans-G?nter@24501 | 7 * in real time. Replication occurs continuously while applications |
| Hans-G?nter@24501 | 8 modify the data on the device. |
| Hans-G?nter@24501 | 9 * transparently. Applications need not be aware that the data is stored |
| Hans-G?nter@24501 | 10 on multiple hosts. |
| Hans-G?nter@24501 | 11 * synchronously or asynchronously. With synchronous mirroring, |
| Hans-G?nter@24501 | 12 applications are notified of write completions after the writes have |
| Hans-G?nter@24501 | 13 been carried out on all (connected) hosts. With asynchronous mirroring, |
| Hans-G?nter@24501 | 14 applications are notified of write completions when the writes have |
| Hans-G?nter@24501 | 15 completed locally, which usually is before they have propagated to the |
| Hans-G?nter@24501 | 16 other hosts. |
