Looking thru the Supermicro AOC-USAS-L8i UIO 8 port sas/sata card thread http://forums.overclockers.com.au/showthread.php?t=759278 Someone posted a link to an ebay seller listing Dell P/N: 0HN359 SAS 5 PCIE Adapter Card USC-51 MY412 Looking at these card they appeared to be cut down / similar versions of the Dell SAS 5/e (8port external) controllers..... except with 4 internal ports. Think of a PERC 5/i without RAID or Memory or Battery and reduced to 4 ports instead of 8. So a 4port internal SAS HBA Looking up specs they appear to be LSI 1068 chipset Being a cheap bastard I thought they might be worth a try seeing as they were listed as BUY NOW for $9.99... Well my 2 arrived yesterday, placed one in my HP ML350 G4 server in the 8x PCI-E slot....but alas loud beeping upon turning it on. Decided I was worth a shot to try the PERC 5/i trick of covering pins 5 & 6 with tape and tried again. Fired right up and recognised the 4 attached drives Installed Opensolaris and it recognised the card as a LSI 1068 SAS HBA ZFS was happy. so far all seems fine. Tried also in an ASUS P6T Deluxe, with the tape trick... didn't seem to work as yet. But I know the PERC 5/i's also have trouble in certain motherboards.... so more testing required on this board. Looking at the PCI-E pins these are slightly different to a PERC 5/i in that pins 1,2,3 are joined together.... where the PERC 5/i has pins 1,2,3 seperate Click to view full size! I didn't upgrade any firmware (looks like the ones I received are the 1st A00 gen versions) but looks like they can be upgraded to firmware A04 as thats available on the Dell site. Upgrade the Firmware HOWTO http://forums.overclockers.com.au/showpost.php?p=12000789&postcount=88 Now I am wondering if they will work with say a Chenbro or HP SAS expander ??
