TrueNAS Core support on lenovo-thinkstation-p3-tower-gen-2-intel-workstation/

TrueNAS General
1

Hi,

I want to know if TRUE NAS Core OS can be installed on lenovo-thinkstation-p3-tower-gen-2-intel-workstation.

Hope there are not BIOS compatibility issues.

https://www.lenovo.com/in/en/p/workstations/thinkstationp/lenovo-thinkstation-p3-tower-gen-2-intel-workstation/len102s0019#models

please clarify.

Thanks,

TrueNAS Scale would probably be a better choice from the listing of supported or installed OSes from your link. TrueNAS Core is based off FreeBSD 13, a version that is end of life, EOL, for the two versions used as a base for TrueNAS.

There isn’t really any other way to know than to test out running it with whatever is installed in that system.

Thanks for the updates.

We have below requirements to be implemented for NAS. Can this be done on true NAS Scale ( but actual requirment from customer is to implement it on RHEL 9.x). We are just doing feasibility study so that can we do it on True nAS scale as it is debian linux based OS.

Please provide your thoughts on this. thanks.

OS Support: Supports CLUSTER SERVER with RHEL 9.x
RAID SUPPORT: RAID 0,1 AND RAID 5 with DUAL PARITY PROTECTION
Other Features: RAID MIGRATION WITHOUT HAVING TO DESTROY EXISTING DATA
NAS REQUIRES THE SUPPORT OF THE FOLLOWING ON ITS OPERATNG SYSTEM:
1) COMMUNITY VERSION OF DATABASE – MYSQL, MONGODB
2) DATA ANALYSIS TOOLS LIKE ELASTIKSEARCH WITH KIBANA
3) COMMUNITY/PROPRIETARY VERSION OF COMMUNICATION MIDDLE-WARE - DDS

Use RHEL 9.x for your feasibility study. You won’t be able to install additional software packages on TrueNAS. It is not designed the same as a Debian or Red Hat distro. It is considered more of an appliance and meant to be used as installed.

You also mention Cluster Server. Only TrueNAS Enterprise has HA (high availability) features that may be like what the customer is asking for.

Thanks for the updates.

Again even though HA is availbale on TrueNAS Enterprise, its commercial license based.

But lot of other requirements wont work on TrueNAS. hence I do the feasibility study in RHEL 9x itself.

thanks for the support.

Just one more question:

these 2 reqs can be implemented on TrueNAS Scale right:

RAID SUPPORT: RAID 0,1 AND RAID 5 with DUAL PARITY PROTECTION
Other Features: RAID MIGRATION WITHOUT HAVING TO DESTROY EXISTING DATA

You shouldn’t use hardware raid with truenas since it uses zfs software raid.
Existing data, if the drives don’t already use zfs, has to be backed up, the drives formatted in zfs, and then restored from backup.
For Raid0,1 5 etc there are equivalents in zfs: stripe (no parity), mirror (sort of equivalent to raid1) or raidz1 ( minimum of 3 disks, with 1 disk parity)

Ok. We are not using hardware raid.

Existing data, if the drives don’t already use zfs, has to be backed up, the drives formatted in zfs, and then restored from backup.
For Raid0,1 5 etc there are equivalents in zfs: stripe (no parity), mirror (sort of equivalent to raid1) or raidz1 ( minimum of 3 disks, with 1 disk parity)

Thanks for the information.

just to confirm.. raidz2 ( min of 4 disks with dual parity) right?

Also I believe we can do migration of existing data in TrueNAS. Pls confirm.

Yes

Migration from what to truenas or Mitragion from truenas to different truenas?

Just my 2c:

Even if Truenas “works” on certain hardware. I think in a business enviroment with clients, its a very bad idea to implement Truenas/ZFS without prior sound knowledge of the quirks and caveats. I would be worried about questions arising about liability in case something goes wrong.

But thats just me.

Yeah, both of those are doable on TrueNAS SCALE, but it helps to think in ZFS terms rather than the traditional RAID.

SCALE doesn’t use classic hardware RAID. If im right it Instead uses ZFS, which kind of maps like this:

RAID 0 / 1 → stripes and mirrors

RAID 5 with dual parity → RAIDZ2 (two-disk fault tolerance)

Hope that answers your question.

Thanks for the headsup.

Its just I have be instructed to learn overall about NAS - on global term, be it on RHEL, TrueNAS, etc so I am doing this feasibility study along with other possibilities.

Thanks.

RAID 5 is single parity mapped to RAIDZ1

RAID 6 is dual parity mapped to RAIDZ2

Oh right, my bad.

Posting this to get your ZFS related knowledge up. It helps if you use the correct terms for everything ZFS related as you will have to explain it to those who are not familiar.
