As such, we put the card itself in a mode that facilitates this use case.ĭue to that, we lose out on any battery-backed write cache the RAID card might offer.
It also has its own checksumming and other algorithms that don’t like RAID cards getting in the way. The H200 is particularly important, as ZFS acts as its own RAID system. H200 RAID card configured for Host Bus Adapter (HBA) mode.x2 Intel X5660 CPUs, for up to 24 threads.
This is the server we’ll be using for these tests for those following along at home, or want some point of reference: Old server hardware is dirt cheap these days, and make for a perfect lab for testing suspicious configurations.

So how can a relatively obscure filesystem designed by a now-defunct hardware and software company help Postgres? Let’s find out! Eddie waited til he finished high school These days, ZFS and Linux are starting to become more integrated, and Canonical of Ubuntu fame even announced direct support for ZFS in their 16.04 LTS release. It wasn’t until OpenZFS was introduced in 2013 that this slowly began to change. ZFS on Linux has had much more of a rocky road to integration due to perceived license incompatibilities.Īs a consequence, administrators were reluctant or outright refused to run ZFS on their Linux clusters. While Postgres will run just fine on BSD, most Postgres installations are historically Linux-based systems. ZFS is a filesystem originally created by Sun Microsystems, and has been available for BSD over a decade.
