(9207-8i is one of the only cards that doesn’t interfere with the BIOS, as dell Implemented it for Tape Drive Support). Boot disks are hooked up internally connected to the onboard sata (I could use USB). I’ve been using Samsung 843TN drives which could be purchased fairly cheaply for a while. They are underprovisioned at 480GB, and feature a supercap to ensure writes in the event of a powerloss. Plus they have a long write endurance cycle. It has worked well so far, outside of some Queue Depth problems with my fibre channel. I was originally going to use the R720XD, but I found that the backplane uses expanders instead of going 1:1. I run a 15 disk RAIDZ6 with a hotspare.<o:p></o:p><o:p> </o:p>-Nate<o:p></o:p><o:p> </o:p><o:p> </o:p><o:p> </o:p>From: OmniOS-discuss [mailto:omnios-discuss-bounces@lists.omniti.com] On Behalf Of Schweiss, Chip Sent: Saturday, May 09, 2015 3:29 PM To: Chris Nagele Cc: omnios-discuss@lists.omniti.com Subject: Re: [OmniOS-discuss] High density 2.5" chassis<o:p></o:p><o:p> </o:p><div><div><div>I have an SSD server in one of those chassis.

After a few bumps at the beginning and giving up on HA on this server, it has been rock solid. Many will swear against the interposers, but combined with Samsung SSDs they have worked very well.<o:p></o:p></div>-Chip<o:p></o:p><div><o:p> </o:p></div></div><div><o:p> </o:p><div>On Sat, May 9, 2015 at 1:06 PM, Chris Nagele <<a href="mailto:nagele@wildbit.com" target="_blank">nagele@wildbit.com</a>> wrote:<o:p></o:p>Hi all. Continuing on my all SSD discussion, I am looking for some recommendations on a new Supermicro chassis for our file servers. So far I have been looking at this thing: <a href="http://www.supermicro.com/products/chassis/4U/417/SC417E16-R1400LP.cfm" target="_blank">http://www.supermicro.com/products/chassis/4U/417/SC417E16-R1400LP.cfm</a> Does anyone have experience with this? If so, what would you recommend for a motherboard and HBA to support all of the disks? We've traditionally used the X9DRD-7LN4F-JBOD or the X9DRi-F with a LSI 9211-8i HBA.
