LSI is the manufacturer of the chip used many HBA's and RAID cards. The chip used on a card will determine features, functions and driver support.

If you look at the last page of this thread, a forum member converted the SDM R4 into a 3D printable:  

I had the 4 drives in the bays connected to my addon card and then 2x SSD's connected to the onboard on an SDM for OS and VM storage, didnt require any additional cooling, however at one point I did h

The card you linked to appears to use a Marvell controller, generally not the best choice for Linux.

LSI based cards work well with Linux and a card configured as 4i4e gives you four internal and 4 external drives:

Thank you!

 

So let's say tat I'm gonna take this LSI card (https://www.ebay.com/itm/IBM-LSI-SAS9212-4i4e-6G-SATA-SAS-Host-Bus-Adapter-HBA-46C8935-46C8934-46M0907/192562587005?epid=23002590603&hash=item2cd59fe57d:g:g5AAAOSwlCdbGpcb).

- May I have enough room to add only 1 3.5" HDD, even with an SDM? (@Trig0r: I understood that 2 would be too much but maybe 1 would be OK?)

- Should I add a fan to cool the card and/or the HDD? If so, where should I connect it?

- Except the SATA cable used for data, I suppose I will need another wire for power. How can I do since I already use 4HDD in the bay + 1 SSD and I can't see anymore power cables in the server?

 

Thanks  again for your help :)

I am really happy to see how helpful is this community!

1. I have never been able to fit a regular 3.5" drive inside the case of the Gen8. At one point I did get a 3.5" drive to fit on the SDM, but it was a Seagate 1TB drive that was slim, 20mm thick. I do not think any drive manufacture continued making a thin/slim 3.5" drive. As for 2.5" drives in 9.5mm thickness they go up to 2TB. In 2.5" and 15mm thickness they go up to 5TB, but they tend to be SMR drives.

2. Depending on the card you install you may need to add a fan. You would need to provide power from either the plug in the ODD bay or split the union above the swappable bay.

3. You can power drives by adding splitters to the power union above the swappable drive bay or using a FDD to SATA power adapter in the ODD: https://www.ebay.com/itm/4-Pin-Floppy-Disk-Drive-to-15-Pin-SATA-Power-Cable-Dell-MX714-Compatible/291282226900?hash=item43d1c60ed4:g:02MAAOSwajVUUqCw

I added a raid card + 8 with sata connectors and added 8 hard drives + 1 ssd of 128gb without counting the 4 disks of 3.5 I do not know if the factory supply will hold ... I realize when I turn it on, it turns off and returns to learn
