Alright, using IP worked, but hostname did not.

Getting invalid origin when trying to set up the admin account. Any idea what I'm doing wrong?

Does NUT for Unraid support multiple UPSes connected to the two redundant power supplies on my R510?

OK, appreciate your help with this. Did the PRO versions of the SSDs have the same limitations re: write speed?

Any idea why the old NAS using the same storage hardware would be able to sustain the increased write speeds for longer? Is it a RAM issue?

Updated setting and made the cache exclusive share. Confirmed exclusive access was yes. Here is the Windows transfer chart now: Initial speeds were over 600MB/s, so we're definitely heading in the right direction. I assume this involves the pseudo-SLC cache on the 860 EVO, which is 22GB and improves initial write speed. However, the file is only 14GB, so I'm not sure why it wouldn't be able to sustain the increased write speed for the whole file.

The share was set to primary: Cache, secondary: none. That makes it exclusive, correct? EDIT: Nevermind, Permit Exclusive Shares is set to No in Global Share Settings, so that must not be enough. I'll stop the array, enable that setting, and try again.

I set up a cache only share and the result was the same. Usually hovers around 290 MB/s. The source disk is a RAID 10 array made up of Samsung 990 Pro NVMe SSDs, so it should have no problem saturating a SATA SSD I would think. I'm stumped :(

The files are being written to the cache pool, which is a pair of Samsung 860 EVO SATA SSDs. Those should be capable of hitting 500+ MB/s, and they were on the old hardware. But they wouldn't be able to max out the bandwidth of a 10GbE connection. The three major differences I can see between the old hardware and the new hardware are: CPU, RAM, SAS controller. The old hardware had a much newer CPU (E5-2643 v3 vs. E5620), 4x as much RAM (128GB DDR4 vs. 32GB DDR3), and an LSI3008 SAS controller. The controller in the new hardware is an older Dell PERC H200 running in IT mode. Could any of those be the culprit?

This is the transfer of a 13.5GB .psb file. Transfer to RACKNAS (unRAID) Transfer to our other NAS (not unRAID) Unfortunately, I don't have a transfer graph for the original unRAID hardware, which showed transfer speeds over 500MB/s.

Hi all, My small business recently set up an unRaid server on an old Dell Tower 7910 that we had lying around. It was running an Intel E5-2643 v3 (2014) with 128GB DDR4 ECC RAM and had a 10GbE NIC installed. My boss wanted to use an old PowerEdge R510 instead, so I moved everything over to that hardware instead. It's running an older Intel E5620 (2010) with 32GB DDR3 ECC RAM and the same 10 GbE NIC installed. On the old hardware, I was able to write to the SMB share I created at over 500MB/s from another 10GbE-equipped workstation. Now, with the new hardware, my writes to the SMB share only max out at around 290MB/s. However, when running a LAN speed test (https://totusoft.com/lanspeed) to the same share using a 9GB packet, I am able to get write speeds over 600MB/s. My array is made up of 7200RPM HDDs, but I have a cache pool made up of Samsung 860 EVO SSDs. Any idea what might be causing the degradation in write speed? Is my (admittedly) CPU/RAM downgrade that big of an issue where it might be causing a bottleneck? Appreciate any help you can provide!
