LINBIT participates in the German Cloud (“Deutsche Wolke”)

 

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, LINBIT DR 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!

Monitoring: better safe than sorry…

It’s ok to be alerted on upgrading a machine because the “old, working” RegEx that did the parsing doesn’t match anymore[1. eg. because /proc/drbd got an additional field]; it’s not a problem to get an email when someone adds the 100th DRBD resource and causes the grep to fail; and so on.

The easiest way to answer things like that is to say look for yourself on the public DRBD usage page – the biggest public device size is ~220TiB, so go figure 😉 Read more
