I’ve been running an all-ssd setup on a Dell R720, with dual 9207-8i cards
connected to dual 8x2.5 disk backplane. (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.

Subject: Re: [OmniOS-discuss] High density 2.5" chassis
I have an SSD server in one of those chassis. Here's a write-up about it on my
blog, there are 3 postings about it.

Not necessarily a build for everyone, but it has been absolutely awesome for
our use. 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.

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:

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.
Thanks,
Chris
