Storage management Software for a LSI 1064e

Actually, that's the big tower model. It may very well have no expander at all, because it can only handle 8 big (3.5") disks in hardware, which means the SAS HBA has enough ports to feed all disks.

I think there might be something funny going on, since the OP's first hard drive is at target 40. I have a SAS1068E card here with the same PCI ID and rev (chip=0x00581000 rev=0x08) as the OP, and the disk on it is target 0.

One of the options in the card's advanced BIOS menu is a display of the SAS topology. I think that's the only way to be sure about the presence/lack of an expander.
