ZFS Orchestration Tools and Wheatstone Adds Linux Audio Driver

Klara ☛ ZFS Orchestration Tools - Part 2: Replication
Automating ZFS data replication is useful wherever the same data sets are regularly transferred to the same target locations. This is common for backups and for maintaining secondary servers ready for failover. Using ZFS to send and receive manually is not as simple as scp or rsync, so some of the tools also provide a simple interface for one-off transfers. However, the performance and efficiency improvements of the ZFS replication feature make it worth the additional setup.
While automatic snapshots were our focus in the previous article, snapshots are critical to ZFS replication because they are the atomic unit of change that zfs send uses to track the current state and the difference in the version of the data on the remote system. The technology behind ZFS snapshots allows for efficient transfers of only incremental changes. Unlike rsync, ZFS doesn’t have to compare the blocks on both sides to know what has changed. Using the snapshots, it can easily generate a list of every changed block between a pair of snapshots using only the birth times of the blocks in question.

Wheatstone Adds Linux Audio Driver
Wheatstone will show a new Linux audio driver for the WheatNet IP network at the NAB Show.
“The audio driver enables bidirectional audio streaming over the WheatNet IP network and is the latest addition based on Linux OS by Wheatstone,” the company said in its announcement.
“Linux is known for its stability as an open-source operating system without the hidden vulnerabilities often associated with Windows OS.” Wheatstone will continue to offer its Windows audio driver.

Wheatstone looks to Linux for NAB Show
Wheatstone to intro Linux audio driver at NAB Show
Broadcast equipment maker, and increasingly software developer, Wheatstone is bringing a WheatNet IP network-based Linux audio driver to the show.
An announcement said, “The audio driver enables bidirectional audio streaming over the WheatNet IP network and is the latest addition based on Linux OS by Wheatstone. Linux is known for its stability as an open-source operating system without the hidden vulnerabilities often associated with Windows OS.”
Wheatstone Director of Product Development Kelly Parker said, “A Linux driver makes sense at this time as one more option for adding greater security and stability across the network.”
