Good to know, I appreciate the help! Do you think ZFS is a reasonable alternative to using RAID here?
Comment on What is a good multirole server setup for a racked server?

Go always with software RAID where possible to avoid vendor lock-in.

Using ZFS on Proxmox for couple of years under different workloads (home servers, productions at job), it is very good.
Just tune it as you need :)

Thanks a ton! I’m on the proxmox forums trying to figure out if I should stick with the H330 that came with the server and return/sell the H730 I got, or if I should use the H730. Seems there’s a recent thread where they’re figuring it out so I’ll get to the bottom of it.

Imo get the H730 if it’s financially reasonable. The passthrough is better supported in my experience. You can resell the H330 fairly easily.

Be aware! The dell R730 most likely comes with a raid controller which is not suited for ZFS. You need a true HBA instead. Some raid controllers do let you set them up in JBOD mode but it still is not suited for ZFS as you need a proper HBA and or a raid controller where you can flash the firmware to IT mode.
For ZFS storage and many apps and more Truenas scale might be interesting to you.

I’ve been reading that the updated firmware for the PERC H730 has no issues in HBA mode, and there’s a thread from December in the Proxmox forums on using an H330 and H730 and they seem to work fine. I’m trying to get more clarification in that thread, but I’ll also do some testing myself.

I run my 730xd with a H730 in HBA for months and Truenas has never had an issue.

Take a look at the following topic. It is not just relevant for TrueNAS but ZFS in generel. truenas.com/…/whats-all-the-noise-about-hbas-and-…

Can you elaborate on the scenario this is solving for? Isn’t software RAID a performance hit?
pztrn@bin.pztrn.name 3 months ago
For me only the case of inability to reassemble RAID array on different server (with different controller or even without it) for data recovery shouts a big “NO” to any RAID controller at home lab.
While it is fun to have “industrial grade” thing, it isn’t fun to recover data from such arrays. Also, ZFS is a very good filesystem (imagine having 4.8 TB of data on 4 TB mirrored RAID. This is my case with zstd compression), but it isn’t playing well with RAID controllers. You’ll experience slowdowns and frequent data corruption.
