Hi all,
I've been using TrueNAS for a couple of years now, with ZFS. I've been reading these forums for a couple of months and decided to join and ask your opinions.
I have a storage server, with these specs:
Processor: 2x 8 Core Xeon E5-2667v4 / 3.2GHz / 25MB cache (16C/32T)
RAM: 512GB DDR4 PC4-17000P 2133MHz
Network: 2x 10Gbit uplinks
SSD: 4x Intel S3700 800GB
SSD's NVMe PCIe: 1x Intel Optane 900P 480GB
Harddisks: 4x 20TB Seagate Exos X20 7.2K SAS 12G
The usage of this storage server will be mainly using it as a storage for VM's over iSCSI. The VM's have different workloads: webserver, gameserver, fileserver, VPN, DNS...
I am planning on using ZFS mirroring for the 4x 20TB, splitting it in half but getting the performance for the VM storage. As for the SSD I will be using one drive as a boot drive. The other three as a RAID0 L2ARC cache (current storage at hit rate of 99-100% of ARC). The Optane drive I will use as a SLOG. Yes, I am using sync=always since I care about the data.
What are your thoughts? Do I downsize the Optane? To what size? Do I use the Optane for multiple functions? Do I use a Metadata vdev? Improvements? Things I forgot? Settings I need to keep in mind?
Thanks in advance.
