Hello,
I have a CSE-846 server with 24GB RAM.
I plan to have a 7x8TB HDD raidz2 vdev in a main pool, but I am thinking about getting 3x1TB or 3x2TB SSDs raidz1 for a dedicated VM pool.
VM workload is media sharing/streaming/transcoding, file hosting, backup services, desktop VMs.
All of the servers should not be used by more than 3 people simultaneously, 1 on average.
I will probably buy an LSI 9211 or 9207 controller with a SAS expander for my SAS HDDs.
I have several questions reguarding ZFS, SSD ans SAS controllers:
1. Should I connect the SSDs to the SAS controller or the on-board SATA controller?
I have read that some SAS controller had issues with TRIM support.
2. Are consummer SSDs ok with ZFS?
I also found threads about some SSDs having issue with ZFS for trim.
3. Is trim something I should worry about for a VM oriented pool?
Thank you.
