TechTalk - ZFS (Zettabyte File System)

ZFS - Zettabyte File System

ZFS (Zettabyte File System) belongs to the new generation of file systems that are better able to meet the requirements of today’s computer centers.

In order to meet the requirements for large file systems, ZFS was given 128-bit addressing, since the limits of 64-bit addressing will be reached in the foreseeable future. The file system will also have an integrated volume manager with the option of setting up a file system on multiple drives/LUNs/volumes.

While data is kept longer on today’s file systems, it may in some cases be used less often. In order to detect disk errors, ZFS uses structural checksums and can automatically repair data errors by working with the integrated volume manager, without interfering with the running application. The repair process can also be run manually.

To improve the data life cycle, ZFS basically operates with transactions when files are changed. This guarantees continuous consistency (provided sufficient redundancy has been configured) Just like NFSv4/NTFS attributes, extended attributes and powerful file service protocols, the basic set of ZFS features includes unlimited snapshots and asynchronous replication.

Ulrich Gräf describes in his presentation the properties of ZFS and compares them with those of the predecessor file systems.

The presentation will be held in German.

About TechTalk

With the TechTalk format, the Developer Garden – Telekom's developers' platform – offers a discussion forum for developer topics and trends in technology. The events begin with presentations and demonstrations from experts. The floor is then opened for questions and discussions. Afterwards, you can meet the speakers and other participants at the buffet, exchanging ideas and making new contacts.

TechTalks are currently taking place in Berlin and Darmstadt. And if you can't make it in person, you can follow the presentations as a live stream and participate in the online chat. We also post videos of the events on our YouTube channel afterwards.
