any experience with Sun 7014391 SAS Expander Assembly 7023751 X3-2L X4-2L

Sun / Oracle 7023751 7014391 SAS Expander Assembly UJ2B-P0051R for X4270 M3 | eBay

does anyone have experience with this sas expander?

i cannt find information about port speed? 6gbps or 12gbps?
is this a regular expander like intel res2sv240 or very specific and only working with sun hardware?

 

By the looks of the ports an the server generation I would say its 12G SAS
Install Storage Drive Cables in a SAS/SATA Configuration - Sun Server X3-2L HTML Documentation Collection

 

the look of the ports doesn't say so much. good example of this is adaptec asr-71605. it has sff-8643 port with 6gbps speed

Adaptec - Adaptec RAID 71605

another question:
how is this expander connected for power supply? i dont see any power connectors

 

You can buy an 12G HBA controller for that Server, but yes there is no info on the net about it

 

How does it get power? I see SAS connectors and 2 Sata connectors, does power come in from the bottom?
