Nick,

Coraid, Inc sold network storage systems that consisted of our software running 
on more or less stock Supermicro hardware. We invented the ATA-over-Ethernet 
block storage network protocol. We sold almost $100,000,000 worth of stuff, 
somewhere north of 10,000 units, all running Plan 9.

I left Coraid the company in 2014 over disagreements with management on the 
direction of the company, and started SouthSuite Software. Coraid, Inc. was 
foreclosed on by the bank in 2015 and I was subsequently able to purchase the 
good parts of the old Coraid, including the brand name “Coraid.” Now, Coraid 
the brand lives on as a product of SouthSuite Software.

Now, we license that same software, or our continuing evolution of it, to run 
on Supermicro hardware our customer buys themselves at a big savings. We also 
support the existing Coraid equipment that is in the field.

You can check us out at http://www.coraid.com

Thanks for asking.

P. S. I still code exclusively in C and see no reason for me to change.
