Did you test SATA drives in the 3.5" bay, and they don't get detected?So, I ordered a few of these to play with, 2 of the 4 had physical damage and can't be racked, waiting on the vendor for replacement. Shipping box and packaging was fine, so I assume they were damaged when removed and not noticed when they packed them up for shipment.
They came with both mezz slots filled, one with a 2x 10gb sfp and one with a 3008 LSI mezz card. I replaced the LSI mezz with a 3108 series mezz, easy swap.
I was concerned if these would be serviceable (replace a HDD) without shutting them down, and to my surprise, they are! You can pull the front of the system out that has the HDD's in them while the unit is running, which allows you to service/swap HDD's, without taking the unit down or out of service...risky but doable.
The 12x 3.5" are SAS only, the 4x front 2.5" are SATA or SAS, and the rear 2x 2.5" are SATA only. The 3008/3108 LSI raid supports the 12x 3.5" HDD's and the front 4x 2.5" SSD's. The rear 2.5" are NOT supported by the LSI raid mezz. There is a PCH bios setting for these rear slots. Not sure if they are fake raid or what, but I haven't found anywhere to setup raid on the rear 2x 2.5" SSD's yet.
Some pics and a short video showing the system and the ability to "slide out" the 12x 3.5" portion of the server - https://photos.app.goo.gl/ftqiaSWYK3WzXctaA
It looks like these were part of some large CEPH or other distributed storage setup at some large cloud provider, they have labels on them with various StorageX notations, storage127, storage4, etc.
that's interesting... is that because of the expander chip they use? The SAS3008 controller certainly can handle SATA, but I assume the backplane has a SAS-(3? 2?) expander (8 SAS lanes vs 12x 3.5" bays)
Not sure, I dropped in the 3108 ocp mezz. The system is 12g sas. The Sata drives I tested lit up as red and the raid bios didn't see them for the 3.5 bays.that's interesting... is that because of the expander chip they use?

most SAS systems can usually handle SATA...
It's a firmware thing 100%. The physical hardware can support it, but depending on firmware, along with the firmware version... SATA tunneling over wideport SAS or also called databolt could be wonky or disabled.Not sure, I dropped in the 3108 ocp mezz. The system is 12g sas.

The 4x 2.5 bays I tested sas and sata ssds and it saw both of them.
I got a unit on Friday and just finished setting it up. The 4 SATA drives I had laying around from 2012 3xWD blacks and some random Samsung SATA2 drive do seem to work with the 3008 card but not with every boot. Some times I've had a reboot where it will not detect a random drive but a follow-up reboot seems to get it to pick up all 4 SATA drives. I've set up a RAIDZ with the blacks and the Samsung as a hot spare and they seem to work normally. I'm gonna try updating the bios and firmwares tonight to see if that helps at all.
Sure no problem there's a Dell r730 mounted above if you need a scale I think those are 26" long? I have a Startech 25U adjustable rack standard 19" wide I've included a pick of what I have it set to as far as the adjustment rails.
The specs show SAS and SATA support. The CCL shows SATA drives. There were issues with the expander on these chassis. There is updated firmware for the expander and the SAS controller, under the download menu:
Do you know how that SAS expander firmware is applied? There's a .bin and .fw file. I didn't see any instructions in the zip file...
According to the readme, you need to install the megacli linux tools to apply the expander firmware.Firmware update:
1. Use "fdl" command to update FW through console port.
2. Use "MegaCli" tool to update FW through Raid Card.
(Please download tool from Avago website. And refer S2PH firmware download SOP.)
