Are you interested in LSISAS2008 Mezzanine cards for the c6100?

[dba]

The holy grail of Dell c6100 mezzanine cards are the 6G SAS/SATA versions based on the LSI SAS2008 chip (instead of the old 1068e chip). I found four of them in one of my c6100s and have been looking for more ever since. They have been nearly impossible to find.

Well, it looks like I might be able to get some at a pretty good price. If I can buy a handful of them, is anyone interested in buying one or a set of four? They would come bare - no PCIe riser card.

I ran some IOMeter tests against five OCZ SSD drives in a dual L5520 c6100:
1MB random reads: 2,601MB/S with 1.27% CPU usage
4kb random reads: 304,804 IOPS with 11.2% CPU usage

Nice and fast!

The older 1068E SAS HBA limits you to hard drives 2TB or smaller. So this would fix that. Would this allow you to run at 6gbps, or is there a 3gbps bottleneck somewhere up near the backplane?

You definitely get 6Gbps from the LSISAS2008 card in the c6100. It's a PCIe2 x8 connection, so no bottlenecks - note the test results I posted.

The LSI 1068e card gives you SAS support and breaks the ~650MB/S combined throughput limit of the motherboard SATA ports. The LSI 2008 card gives you SAS, 6Gbit, large drive support, and LOTS more total throughput and IOPS.

In tems of cost .. will these be more, the same or less $$ than the 1068e mezz card ?

Do the 2008 mezz cards use similar cables to the 1068e mezz card ?

The two cards use the same cables. The cost will be around $170, which is definitely more than the 1068E version.

Are they all RAID card?

They support RAID 0, 1, 10, and of course JBOD. Basically they are the same as an LSI 9211 or an IBM M1015, but in a mezzanine format that is proprietary to the Dell c6100, C6145, and C6220 servers and with six disk ports instead of eight.

How is the cabling? SFF-8087 breakout cable?
I might be in for 2!

Update: Sorry. All sold.

I have received my bulk order of these cards and the cost was actually a bit less than I thought. I'm putting the extras up on eBay:

Dell 6g SAS SATA MEZZANINE Card LSI SAS2008 for C6100 C6145 Part XX2X2 | eBay

If anyone on this list needs one, I can sell them for $140 to STH listers. Please read the eBay item in detail - you'll still need the riser card, cable (I also have these), and a motherboard with SAS card attachment points. If you are replacing a 1068e mezzanine card then you already have what you need. If not, then it might be a difficult refit.
