Hi,
what I have at the moment:
Thanks a lot in advance,
Thomas
what I have at the moment:
- A Windows-based system.
- Intel Core i5-4690S
- 32 GB RAM
- Adaptec RAID Controller
- 8x HDDs
- The whole system consumes in 24/7 low load state (all drives spinning, all VMs on low load) around 130 W.
- TrueNAS CORE as NAS + Proxmox VE for virtualization.
- Data integrity of the stored data has highest priority.
- If anyhow possible the new system(s) should consume a maximum amount of power comparable to my current system (or if not possible, only minimally above).
- My information so far:
- Running TrueNAS and Proxmox on the same system is not recommended, because
- Virtualizing Proxmox on top of FreeBSD bhyve makes no sense, because of nested virtualization.
- Virtualizing TrueNAS in Proxmox and passthrough of the HBA could risk the data integritiy if something goes wrong and it makes troubleshooting more complex. Virtualizing TrueNAS on top of Proxmox is also officially not supported in the TrueNAS forum.
- Going with ESXi (as recommended in the TrueNAS forum) is not an option for me, because Proxmox is much more user friendly.
- My current approach is trying to find two low-power systems, one for TrueNAS and the other for Proxmox (and with this point I would like to access your experience).
- Running TrueNAS and Proxmox on the same system is not recommended, because
- The TrueNAS CORE system:
- Power Consumption: From other systems running TrueNAS with 8 drives, it should be possible to reach a low load power consumption with spinning drives of around 80 watts with the CPUs mentioned below.
- CPU
- The CPU should have a very low idle power consumption.
- I'm thinking about an Atom C3758, Pentium D1508, Xeon D-1518. Do you have any better recommendations? Which CPU would you use?
- Mainboard
- Supermicro mainboard preferred
- ECC RAM
- IPMI
- >= 8 SATA/SAS connections
- Network: SFP+ preferred (for 10 GBit/s network, because 1 GBit/s would limit even the relatively slow RAIDZ3)
- Chassis with Hotswap for the drives (not decided, yet, if 19" or desktop chassis)
- Storage:
- I tend to use a RAIDZ3 (8 HDDs)
- The Proxmox VE system:
- What shall be virtualized:
- Plex
- Syncthing
- Nextcloud
- UniFi controller
- FreePBX
- Gitlab
- 2 VMs running Win 10
- 1 VM running Docker
- Power Consumptions: With my goal of 130 watts and 80 watts for the TrueNAS system, we have around 50 watts left for the Proxmox system. Is this possible with my requirements?
- CPU
- The CPU should have a very low idle power consumption (all virtualized instances are usually running in idle).
- Plex should be able to use the CPU for transcoding some (1..2) 1080p and 4K streams. For this, the CPU should contain an integrated GPU (especially for the 4K transcoding stuff).
- Mainboard
- Supermicro mainboard preferred
- ECC RAM
- At least one PCIe slot (for a Hauppauge WinTV-Quad HD card passed-through to Plex)
- IPMI
- Network: SFP+ preferred (for 10 GBit/s network)
- Storage: Two mirrored SSDs for the system (all other data will be accessed via network on the NAS).
- What shall be virtualized:
Thanks a lot in advance,
Thomas
