I really get turned off when people post a picture and walk away with little to no detail. What are you trying to accomplish?

Thanks to everyone who answered. I didn’t provide any details because as the saying goes, one picture is more than 1000 words worth…

Yes, the “System 1” is a JBOD with a SAS/SATA 16 Ports backplane, that will run a mix of sata/sas/ssd’s hard drives. This must go with no witchcrafting to the “System 2”, as … pictured.

I also consider a 4 x 8644 external HBA, but until now I only managed to find some LSI/Broadcom/Avago cards that are too hot and maybe fake chinese ones, with no guarantee of data/firmware/functionality. And the prices are also too high.

I,m already over my buget.

[Update]
I managed to do some preliminary test, by connecting 4 drives (2 x SAS, 1 x SATA3, 1 X SSD SATA3) as pictured.

I have tested using an Adaptec 71605 (4 x 4 8643 ports) and found some strange “happenings”.

When connected directly into the Adaptec card, all seems fine. But when connected through the AOM-SAS3 external 8643 to 8644 adapter, the SSD SATA3 strangely “drop” to 3.0 Gb speed, although the SATA3 HDD remains at 6.0Gb:

Now this is really strange.

I’m also found a 8644 16e 12Gb HBA card that must arrive. I will update the post
