greetings, all!
wondering if anyone has experience using a ZFS raidZ2 disk pool for
audio. i'm talking about a LOCAL pool, running on ZOL
(http://zfsonlinux.org/) -- NOT a LAN-connected dedicated server.
here's an interesting test case, which seems to show entirely adequate
throughput for multichannel audio applications:
https://bit.ly/2ryO9xr
(that's with openZFS on freeBSD, but i'm assuming performance should be
similar on linux)
looking forward to any thoughts y'all might have on this!
Had extremely positive experiences with it about eight years ago. I
used to produce some gcc packages for FreeBSD, and that meant having
about four gcc builds running in the background at any given time. I'd
regularly do this and *still* have glitch-free audio whilst the builds
were going on. This was on an early Core i7 machine with a three-disk
zraid array (two disks striped plus parity). I think part of the
reason it seems so fast is that the built-in compression seems to
reduce traffic on the SATA bus quite considerably.
I have no experience running ZFS on Linux though. I've resigned myself
to running ext4 there. Still running ZFS on FreeBSD to handle file
serving and backups though.
