I purchased 2x2U chassis off eBay which came with BPN-SAS3-216EL1 backplanes. On both of them, I found one capacitor that fell off at different locations. No biggie I guess. I ordered two refurbished backplanes also from eBay and when they arrived today I noticed that one of them had...

Gotcha, thanks for the reply, thought I was going crazy or something

I just realized a few of my servers fitted with 9308 cards are in IR mode instead of IT yet they work just as fine. I always thought/knew that IR made meant the HBA doesn't present the drives directly to the OS, etc but that doesn't appear to be the case. The OS sees the drives...

great advice - thanks!

Bought a brand new x10drd-i motherboard. Managed to get some non-conducting thermal paste in the socket. How screwed am I ? I tried cleaning with alcohol, q-tip and a microfiber tissue. No luck, it's deep on the socket below the pins and I'm afraid to bend them. Tips ? https://ibb.co/JtmwmfB...

Thanks, and it remains on like that all the time ? It's kind of confusing I find

I bought some brand new HUS726060AL5210 HGST 6TB 7.2K 12G 128MB 3.5" SAS Hard Drive and when I put them in a SuperMicro JBOD chassis, the blue light remains on. I've put other drives in these chassis via hotswap and the light doesn't remain on... but these do. What does it mean exactly ?

I purchased a brand new CSE-216BE1C-R920WB from Wiredzone and I populated it with a dual Xeon X10 motherboard, V4 cpus and LSI 9311-8i HBA. All the components are brand new and the server has been working flawlessly for the past 60 days but last night I wanted to add 2 new drives to it while it...

I must be doing something wrong. I also have a similar setup, running: E3-1270v6 with 64gb of 2400mhz ram. Since this CPU only has 4 cores, I run 2 plots staggered about 2h apart, each to its own S4510 SSD. I do 6.5 plots per day..

Jeezus...my hardware is not meant for this. So that Ryzen with 16 cores apparently has higher performance than my 2 x e5-4627v2 @ 3.3ghz which also have 16 cores total. I'm just going according to CPU Benchmark here which gives the Ryzena score of 46 000 and one 4627 a score of 9600. How can...

So you are doing the same as me, since you have 3 fusion-io cards. With a single one you'd be doing 8, just like me. I ordered 2 x 4627v2 cpus - 3.3ghz 8 cores each vs 2.1 ghz 6 cores each with the e5-2620 I'll see if it improves. What speed is your RAM ?

thanks!

How are you guys getting 40-50 plots per day ? Does CPU speed matter that much ? I have a dual xeon e5-2620v2 running 4 plots staggered via plotman ( Ubuntu ) on a single Fusion IO card and it barely does 8 plots per day. I can't image the Fusion-IO card being the bottleneck...or could it ?

the E5-4XXX are meant to be in quad cpu systems, but will they work with Supermicro dual cpu motherboards ?

Answering my own post :) The * after the CPU ID is to differentiate which one is CPU 1 .. even though it says so in the column above. This is according to SMC Also the issue went away after I downgraded the RAM speed to 2133 Mhz. Not sure why, it's supposed to work @ 2400Mhz, even SMC says so...

I have an X10DRW-iT motherboard with 2 x 2683v4 CPUs and 4 x 32Gb Hynix RAM. #1. In the BIOS, CPU1 under CPU Configuration -> CPU ID , it prints the ID with a * at the end. Does anyone know what that's for ? #2. What is the correct memory population with 2 CPUs and 4 DIMMS ? I put it in slots...

yep, that's what I figure even though there are no such warnings in the OS/IPMI. What stress test can I use to single this out ?

This server runs only a single app, it's on FreeBSD 12.2. 6 other similar servers with similar hardware specs, also FreeBSD 12.2, same app, run just fine. The app basically stores files to disk and writes their CRC at the same time. About once per day, an invalid CRC gets calculated. About...

After a very long app debugging process, the developpers are 99.9% sure one of my E5-2620v3 cpus have a faulty l1/2/3 cache. I only tested using memtest86+ Pro and it found no errors but I understand that memtest disables all caches and just tests the ram. Is there an app to test the cpu caches?

Update #2. These are matching items that can replace the SMC items: Standoff: https://www.mouser.com/ProductDetail/728-FM2146-3005-SS Screws: https://www.mouser.com/ProductDetail/534-29311
