The only place I've seen them repeatedly are eBay. There are 2-3 new listings per week for the expanders, they usually go for ~300 or a bit less depending on the exact model.
Got my HP SAS Expander, but when turn off SES2 in GUI (cant find it in biso) My main raid is gone. Turn it on agan raid is back agan. So long SES2 is on, cant find my test HDD :/
My Raid card is Areca 1680IX-16

Hello,
I have read this thread with great interest. I was wondering if anyone has tried this HP SAS expander card with an LSI SAS3801E controller card or any of the LSI family with the Fusion MPT architecture?
I am specifically interested in this card as I am looking at using the expander with a system running either Solaris 10 or Open Solaris and ZFS.

You won't be putting it in a PCIe x1 slot unless the end is open. It has a PCIe x8 connector, so you better make sure you have room to accommodate it. However, electrically, it doesn't require anything more than a PCIe x1 slot (if even that).
This is what I use: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131228
Quad gig LAN means I can put the RAID card in the PCIe x16 slot and the SAS expander in the PCIe x8 slot and that's all I need. NICs aren't Intel, but you can't argue with this:
Why not use some normal 8088 and 8087 cables along with an adapter along the lines of this? http://www.pc-pitstop.com/sas_cables_adapters/AD8788-1.asp
Well, my 1680i should hopefully be here on Wednesday. I can part with my 1680ix-24 then if it works as planned.
Why do you need so many NICs? You might as well get a single 10gbit NIC if you need that much throughput anyway. Not like you could saturate 8 x 1gbit connections with the RAID card anyway considering it only does 800mb/s on continuous reads, and even less on simultaneous requests. I found the 450mb/s my 4 NICs provide to be more than adequate. Also, keep in mind you'll need a rather high end quad core to even handle that much network traffic. My Q6600 was at nearly 100% with all 4 NICs being pegged.Not enough PCI-E Slots
I need one with atleast 3... preferably 4-5, only needs to be single CPU as well since its ONLY going to be fileserving.... but i need the slots for more NICs, box is going to need 6-8NICs for sure.
I plan on building 3 nearly identical boxes assuming this Expander works as expectedm and i finish this proof of concept box
All the expanders I've come across have external ports as well, so you would not be limited by that card at all. Adapter should work fine, but try not to go crazy with cable length when using SATA drives.I didn't know there is a such thing exist.
That's a great way to expand the number of external ports. It will work the same as external 8088, right?
I just bought the Areca 1680x and now I feel regret. I should get one with more internal ports instead. Do you think it will work if I get the 1680ix and then use the 8087->8088 adapter to convert one or more of the internal ports to external?
I had issues with my 1680ix-24 when using the internal expander and an external one. I bought a 1680i because I got a decent price on it, but any of the 8 port cards would have worked for me. I also sold my 1680ix-24 because it was cheaper to buy 2 SAS expanders and an 8 port card than it (and I even got some more money back on top of that).hi blue fox, why part with the 1680ix? Is the ix not as good as the i ? I need a card with two external SAS connectors for my 8-bay enclosure, but I also want to be able to add SAS expanders in the future. Which card in the 1680 series you recommend?

I disagree. The 1680x is the ideal card especially if you are planning on running multiple chassis. It's not ideal to attach the HP expander to an internal port on a 1680 "ix" card since then you're effectively daisy chaining expanders and there may be issues since it's two different expander chips in sequence. I think I tested this once but results weren't good. I'll try to re-test and confirm.
6 to 8 single NIC channel cards or are you looking for a total of 6 to 8 channels?
If you are looking for 8 channels, get two quad channel PCI-E NIC cards...
Why so many NICs anyway?
