Non-PCIE SAS extender backplane?

[GreenDream]

I come in peace. Linus' videos convinced me to join this temple of knowledgeable people

 

More seriously, I wish to know what exists in terms of SAS extender backplanes.

 

Is it possible to have an extender backplane that does not need to be plugged into a PCIe slot?

 

If so, what do you recommend on Ebay?

Most sas expanders don't need the pcie slot, its just for power. So you can just mount it somewhere else in the case.

 

How about this one?

Thank you.

 

I figured that PCIE is just for power.

 

Does this card have inputs to connect it with a SAS HBA?

 

I suppose there is a standalone PCIE connector that be powered directly by a PSU through SATA power or molex.

Ye you need anouther sas hba to use it.

 

That card has a molex connector for power.

I see the white molex connector and will do some research for what I need.

 

Thanks again for your insights.

You can use any of the SAS ports to connect to your RAID card or HBA. I have 2 RES2SV240's, connected to a LSI 9271-8i RAID card (one to each SAS port on the RAID card), providing 40 SAS connections. You can use either the PCI-E slot or the Molex connector for power...it just provides flexibility.

How do you connect the LSI HBA to the RES2SV240?

 

I looked at the Ebay listing above but do not see where the input cables should go.

You use an SFF8087 to SFF8087 cable into any of the 6 available ports. So you will have 5 available ports for connecting devices. 

SAS is quite a universal standard like USB, theres no dedicated Input/Output, everything is just addressed via SAS Addresses.

Oh, so there's no dedicated port(s)?

 

That greatly simplifies things.

 

Sounds like I can just get an expander card to take off the metal bracket and find a way to screw it down somewhere in the case.
