[Grants] Grant Application from David M Williams for RISC-V hardware

[Russell Coker]

For this application I think that the 16/128 modules (16G of RAM and 128G of 
storage) is the correct choice.  Nowadays you can't do much in the server 
space with only 8G of RAM and while optimising things for RAM efficiency would 
be a good thing to do, having it work on 16G first would be best.  Also for 
educational purposes a cluster of 16/128 modules could provide 14*6G VMs or 
21*4G VMs which could be really good for running a training course.

Another reason for getting the bigger modules is that 32G of storage isn't a 
lot and the cluster doesn't appear to have any options for connecting M.2 or 
SATA storage so more storage on device is needed.  128G also allows for 
experimenting with cluster filesystems, 7*100G storage nodes connected via the 
built in GigE might be usable for a Ceph setup with 16G of RAM per node.

I also recommend getting the version with the chassis as the chassis is cheap, 
looks like good quality, and the grant application is NOT for hardware work 
but for software work.  So paying extra to avoid hardware hacking is 
appropriate.
