Examples...It seems to me that most of the popular raid cards you discussed is 8i. Can anyone give me a quick answer please?
If you want just a HBA (no on-board RAID), the 9201-16i is probably the best solution. Note that the external (-16e) version is often available used for a lot less money - some people are buying those and using a SAS bulkhead connector and cables to get the ports back into the chassis.It seems to me that most of the popular raid cards you discussed is 8i.

Like it your way. But eBay give me $60 for 16e $350 for 16i. :-(If you want just a HBA (no on-board RAID), the 9201-16i is probably the best solution.

Personally, I like the neatness of custom internal cables on a -16i card:
A lot depends on the percentage of the total system cost. If you're using 16 * 8TB SAS drives like I do, the controller cost is such a small part of the system cost that it doesn't matter (to me, at least). On the other hand, if you're using drives like the 450GB for $15 drives in the great deals forum, then the controller costs more than a set of 16 drives.The 9201 16i's are ridiculously expensive.
Another possibility is to use a expander backplane (assuming SAS controller / expander / drives). If you aren't using SSDs there should be plenty of bandwidth on eash SAS port. And if you have a chassis that holds more than 16 drives, you're probably going to use an expander anyway. I don't use SATA drives on SAS expanders (I do use SATA drives directly cabled to the controller when necessary). I've had too many problems with SATA drives and SAS expanders - even if the issues are fixed in some newer hardware, I've been burned too many times before to be willing to try it again. The issue is that everything works fine most of the time, but when a drive acts up, the expander just goes "resets for everybody!" and all of the drives drop offline.Its just like Terry Kennedy said, some people buy the 16e and 8088 to 8087 adapters and route those bad boys back inside the case. I was contemplating this me-self, but seemed too messy. Although, with alittle work, this could be a neat and cheaper solution.
A couple of things to note:Another card I actually recommend, which goes for about $100 cheaper than the 9201 16i is the Marvell/Syba PEX40097 for about $200. Amazon has them pretty much all the time.
A simpler method maybe to use 4 @ sff 8087 to sff 8088 cables , very common and cheap, this was just a very quick search to get these 2., ( 1m @$15) and ( 2m @$32) available, please excuse me, if my agricultural engineering is too primitive, just using KISYeah, Marvell controllers used to be quite horrible, but they have improved greatly. I use a couple of the pcie x 1 versions of the 16 port card in my htpc.
You're right about the SAS expander issue though Terry. Should only use them if thats the setup your going for. I personally like to have all my drives connected to a port each on their own. As for the Marvell card, as long as the op (Primez) is using sata drives, the Marvell card should be ok though. Notwithstanding the price......still cheaper than $350, but you still gotta cough up $200 bucks, and all for alot less bandwidth. I do love the card though. My brother got one for his server.
If I had to vote, I would be going with the 9201 16e and buying this bad boy to route the ports back inside my case:
Mini SAS SFF-8088 to SFF-8087 Adapter 4 port Quad port, w/standard PCI L bracket
Now,
lsi 9201 16e = $50 (Seller will take $50 best offer. Thanks to Nthu9280's awesome info)
LSI Quad Port 6Gb/s PCI-E SAS Host Bus Adapter SAS9201-16e (7340)
+ quad port sff 8088 to 8087 adapter = $100
Mini SAS SFF-8088 to SFF-8087 Adapter 4 port Quad port, w/standard PCI L bracket
+ four sff 8088 cables = $38 (if you search around, may find it cheaper. I like the short length though)
Molex SFF-8088 0.5M 19 Inch Mini SAS External Cable 407344-001 408765-001
Total = $188 bucks. Cheaper than the Marvell card, and still getting great bandwidth on the x8 slot. Also, Lsi's excellent OS support.
9201-16e it is!
Wait, that is, if you got a x8 slot, and a spare pci bracket area available to mount the quad port adapter in your case/chassis....
