Ahhhh, I figured it was after you registered, just wanted to ask anyway. I'll register one of mine and check it out.

They had QSFP+ to SFF-8644 cables for cheap (compared to other vendors) ==> 10Gtek 4x Mini-SAS HD (SFF-8644) to QSFP Cable, 1-Meter(3.3ft) (36$)SAS 9206-16e Host Bus Adapter
Has anyone tested this..or its variation?
Dell rebrands it to SC 8000
Edit : Gene said earlier it would get hot without additonal cooling.. Any other recommendations?
Preferably under 150
Looks like i have 2 options here...
2x QSFP to SFF 8644 + SC 8000 card (~$200) or
2x QSFP to SFF 8088 + SFF-8087 to External 8088 Adapter + M1015 card (~$160 without the card)
cabls found from this site
QSFP to MiniSAS(SFF-8088) DDR Cable 0.5M | QSFP MiniSAS
Anyone bought their cables?
Which one should i choose?
Absolutely not. SAS != Ethernet.I wonder if instead of using SFF8644/SFF8088 to QSFP, you could use the QSFP to 4x SFP+ breakout cables to a 10GBe router/switch and just have everything routed through that without having to do direct attach.
Would that work in theory?
I dont think i have anything else to test it with..That's kinda strange. I had a similar issue with my 9201-16e cards but after updating to the latest firmware it finally saw them.
This is going to sound silly but have you tried hooking anything else up to those cards to see if it will see anything at all?

Yes you have to unplug it to turn it offEdit : problem solved ! Had to use -fwall firmware to update all of them..
Now it's detected but as SAS in disk manager..
Another thing i cant figure out.. How do i turn off the enclosure? Is it safe to just unplug it?
Infigired it was the firmware as it was acting just like mine did. Prior to update it acted like it was just dead. Glad you got it running. Mine gets toasty as hell as I don't have a fan blowing directly on it. It's currently in my SM 846 chassis so it gets enough air right now. But a lesser rpm fan and I'd be in trouble!Edit : problem solved ! Had to use -fwall firmware to update all of them..

I don't have anyway to test it as I don't have a new ups yet. But from the other comments at the beginning of this thread I thought I read it idled about 55 watts with no drives running on a single power supply.Anyone investigated how power efficient those are?
Thinking of moving my disks from my SC847 to the HGST and using a smaller case for the host, diskless.

Now that i think about it, i think it's more likely caused by heating issue..Yes you have to unplug it to turn it off
As to the 9201-16e i had to add a fan blowing onto it to keep it from crashing and dropping all drives until reboot
