No. I'm the one who got the quote and set up the order for my managers,
and I know what it's got: the ethernet connection is to the internal
webserver to manage the RAID. the 712S I have is dual-path SAS for data.

then yeah, you'll need a plain SAS2 external HBA card.   If your server 
is older, with PCI-Express v1 or v2, then a LSI 9211-8e or similar would 
be fine (IBM M1015 are a common cheap OE version of the same thing), as 
long as you flash that to be in "IT" (Initiator-Target) mode as they 
usually come in IR (Integrated Raid).  If the server is PCI-Express v3, 
then you'll want a newer card based on the LSI 2308 chip, such as the HP 
H221 I mentioned)

It's an old box, a DL580 G5. And we didn't get the card with the RAID. I
suppose I can single path each RAID from the PERC H800, until budgets open
up.
