As you might know, DRBD Manage is a tool that is used in the DRBD9 stack to manage (create, remove, snapshot) DRBD resources in a multi-node DRBD cluster. DRBD Manage stores the cluster information in the so called Control Volume. The control volume is a DRBD9 resource itself which is then replicated across the whole cluster. This means that the control volume itself is just a block device, like all the regular DRBD resources. Continue reading
When DRBD 8.4.4 integrated TRIM/Discard support, a lot of things got much better… for example, 700MB/sec over a 1GBit/sec connection. Continue reading
Have you ever wanted to do a file based backup of your data without impacting
your application, and without stopping your HA replication? Here is one
possible method. Continue reading
Every now and then we get asked “why not simply use a mirrored SAN instead of DRBD”? This post shows some important differences. Continue reading
Deutsche Wolke (“German Cloud”) was founded to establish Federal Cloud Infrastructure in Germany.
This infrastructure will provide additional legal and security protections for hosted data. No longer will small businesses be exposed to the legal risk of losing their website presence without a trial (an unfortunate reality when doing business on transatlantic clouds).
The natural partner for backend storage infrastructure is LINBIT; as authors and maintainers of DRBD, we are best suited to provide the technical expertise to achieve High Availability. Also, DRBD Proxy is the obvious choice for off-site or disaster recovery replication (from the office into the cloud).
We at LINBIT look forward to seeing this project grow and prosper!
