Hello everyone,
I'm just getting started with TrueNAS, so please indulge me
In order to reduce the number of devices running in my homelab (electricity is getting expensive in Europe), I have a somewhat ambitious project which is to replace my Synology NAS dedicated to VMs by a pair of TrueNAS VMs with connection to physical disks on my 2 ESXi hosts.
For redundancy reasons, the storage will be accessed by iSCSI on the 2 VMs frome both hosts via two dedicated 10 GB/s network cards (VMs and hosts), allowing storage vMotion, storage DRS, etc... The hosts are pretty beefy, so I'm hoping they'll be okay.
I've already tested the basic concept, everything works: the LUNs are visible, you can put VMs on them and it works apparently fine but before migrating everything I have a whole bunch of questions concerning several levels of configuration and which are:
Hardware:
I plan to reuse the SSD disks (Samsung 1 TB EVO) from my NAS. If I buy 2-3 more, I'll have 3 or 4 available per TrueNAS VM/ESXi Host. What would be the best configuration for the pool/vdevs/zvols? I'm really trying to get my head around this, but it's not easy.
- Should I go for a 3 or 4-disk raid concept, or should I do something else?
- Is there an optimal vdevs/zvols configuration (knowing that 2 TB of available storage is the minimum I want per TrueNASVM)? Please feel free to give me size indications.
Software:
- On the vdev, what values are optimal (Sync, Compression)?
- What about compression and dedup on the zvol(s)? To avoid overloading, isn't it better to leave everything disabled?
- Is it better to use a large LUN linked to a large zvol?
- on the extend, what are the desired values for the zvol?
- If I ever add another volume with a different disk concept from the main pool, is it better to have several targets?
My workload is a mix of Windows, Linux and netsted labs. I have between 40 and 50 VMs running all the time.
I know that's a lot of questions, but right now I feel like my head's going to explode before I understand it all ... my thing/job is VMware, storage is another world!
Thanks in advance to anyone who can enlighten me and show me the way.
