If the CPU can’t handle iPerf >1Gb/s, which is essentially just throwing bits from the CPU to the NIC, I don’t think it’ll handle any file transfer protocol faster than that.
BACKGROUND
- Upgraded my unmanaged switch to a Linksys LGS326 w/ LACP support
- Connected 2 LAN ports to each of my 3 QNAP NAS(s) running TrueNAS CORE
- Enabled LACP in both TrueNAS CORE and LGS326 (have to do this simultaneously)
- Have to manually restart mDNS or reboot to restore access to shares
RESULTS
- I can see when I have multiple RSYNC tasks running, traffic is distributed across ports in the LAGG
- CPU load not maxed out on either side
- LAGG interfaces working with jails and VMs
- Ran two iperf3 instances to confirm I am getting ~1Gbps on each simultaneously
Server
iperf3 -s -p 5201 &
iperf3 -s -p 5202 &
Client 1
iperf3 -c {server ip} -p 5201
Client 2
iperf3 -c {server ip} -p 5202
Confirmed both clients are getting ~940Mbps simultaneously.
@elvisimprsntr Thanks for sharing.
I am curious, what model Qnap NAS do you have and what do you mean by it running Truenas Core ? Did you overwrite the QTS with Truenas ?
BACKGROUND
I have 2xTS-453A and 1xTS-253A, which are all x86 based and first confirmed the SATA and LAN controllers were supported before installing TrueNAS CORE on an external USB3 Crucial X8 M.2 QLC SSD.
Once I got everything configured and ran for 2-3 weeks without any issues, I replaced the stock Apacer 512MB eUSB DOMs with Apacer 16GB eUSB SLC DOMs, and re-installed TrueNAS CORE and restored the config backup. eUSB DOMs are hard to find right now due to chip shortages, but I was able to find some. Although not recommended, you can run CORE on thumb drive, but they will not last. At a minimum, use industrial SLC thumb drives.
RESULTS
- TrueNAS CORE runs on my hardware without issues and is significantly faster than QTS.
- CORE bhyve hypervisor is a bit finicky and doesn’t natively support USB passthrough, but I was able to get a Windows VM working after some tweaks.
- Even figured out how to control the 16x2 LCD display on the TS-453A
- I tried TrueNAS SCALE ALPHA, but its not stable enough for critical environments. I plan to migrate to SCALE after it’s out of BETA and @LTS_Tom gives his seal of approval.
YOUR OPTIONS
- The QNAP TS-231 is ARM based, thus will not run CORE
- Pick up a used x86 QNAP or other manufacturer NAS off eBay, or repurpose an old PC, and use the TS-231 as a backup NAS. Just stay away from Intel CPUs that have the LPC clock degradation issue. Silvermont - Wikipedia
