NP, sounds like we have the same setup (or very similar). I have a multibay server running storage arrays on Supermicro and a desktop with X58 + hex core xeon that's super fast but long in the tooth so no USB3.0 and SATA3. I've also added those features with an add-in card and so far so good.
The eSATA(p) and USB3 is for my desktop.

if you have HBA card, 2 minisas connection to SM backplate is possible, assuming you need more bandwidth, plug second minisas that located next on first minisas
or
if you have Hadware Raid card, ONLY 1 minisas is supported, this is limitation on HW Raid. tested on IBM OEM 9260.
Actually the 2nd Mini-SAS expander chip port is on left side of expander for this backplane. If you're doing dual path, you'll need to plug in the 2nd and 6th Mini-SAS ports counting from left
If you need a short cable to connect a HBA to the expander OEMXS has them too. 185mm

if you need failed over, yes!!
if you need to connect 2 minisas on the same HBA... there is NO documentation from supermicro, aka unsupported.
I was fallen on the same trap as you described.
HBA card detected 2 minisas, but with errors. verified by running cmd line under linux.
I need to stick with the same chipset expander mini-sas connetors to utilized 2 minisas connections.

the neat one is, I can make solid red, blinking blue, or solid blue vua sg_sas, as long as I know the drive location, 0-4 (most left-up to most left-bottom) and so on.....
Good point, another Supermicro trap as you mentioned. I'm starting to find all these little undocumented nuances for which we users are the beta testers. Reminds me of the X8SAX motherboard I was looking at 3 years ago for Vt-d support, only 1 version of BIOS supported it but that version won't let you run all 6 RAM slots, seriously?!
Speaking of blinking LEDs, is there anyway to get individual drive activity signal from this Intel Expander? My older drive cage doesn't seem to work with bus based signal
I need some help..
I am trying to build a JBOD Disk Chassis. Below is the components I currently own or plan to purchase.
Server Chassis
Supermicro 3U Server chassis (already own)
LSI 9260-8i Raid Card (already own)
JBOD Disk Chassis
Supermicro 4U chassis (SC846TQ) with 24 drives (already own)
Supermicro JBOD Power Control Board (CSE-PTJBOD-CB1 or CSE-PTJBOD-CB2) (need to purchase)
Intel-RES2SV240 SAS Expander (already own)
My question is how do I connect the 24 drives in the JBOD Disk Chassis to the LSI 9260-8i Raid card in the server chassis? Please provide detail steps and a link to the additional parts I need to purchase.

That backplane has no expander so he definitely needs the RES2SV240. That being said the link to the 9260-8i will take at least one connector (4 ports) so he'll only be able to use 20 drives with one expander. He could connect 20 drives through the expander and connect the other 4 drives directly to the RAID card assuming he's not using the second connector for drives internal to the 3U chassis.
edit: And he will need fanout cables with that 4U chassis as it doesn't have sff-8087 connectors.
MY BAD!
I had stupidly just assumed that chassis was the same I had after looking at pictures.
Let's keep in mind the 9260 is in a different chassis, so he'll do to do SFF8087 to SFF8088 external, then SFF8088 back to SFF8087 into the JBOD chassis, then 1 link to the expander and 1 directly fanned out to 4 drives. Personally I'd get an 8e card just to avoid having to convert the cable twice for more points of failure
I've been known to go 8088 to 8087 internal w/out the 'adapter' just through a slot in the back or with no IO shield it fits through there too... I only know because I forgot to put the IO shield on and used an external RAID card to my expander, to fanout to test the cards.
I'd just have gotten a backplane with an expander in it, ie: a cheap supermicro 24bay off ebay then its just plug and play, and go, no converters, extra cables, fanouts, etc... probably ~same $$ after you add up the cables, fan-out cables, internal to external converter, and sell the chassis you have. (Or just replace backplane with expander one)

(Or just replace backplane with expander one)Of course improvising works as well, but I'm a little gun shy after a faulty/loose cable almost took down my xfs array a few weeks ago. I agree with you though, if going rack mount definitely get backplane. Cables $ add up quick, but you do lose flexibility if you pass through the controller if backplane is expander and not breakout
Unfortunately I already have the 9260-8i card. For the 1 connection directly fanned out to the 4 drives, is there a clean way of connecting the JBOD chassis to the server chassis?
Are you telling me that the backplane on the SuperMicro 846TQ is only capable of handling 3Gb/s and not 6Gb/s?
For the SFF8087 to SFF8088, I would need the Supermicro cbl-0167l-lp unit? Please confirm.

Honestly after 3-4 cables to do it properly might as well get a 8e raid card probably another $30-40. Sell the 8i and recoup cost
