Hi Steve,

re: what you will be doing with your new LDM machine: simple relay or beefier

> It is the latter use that we are intending.

OK.

re: 128 MB RAM

> I assume that's 128 GB of RAM.

Oops, yes I meant 128 GB.

OK.  15 TB should be enough to keep about a month of data with the
current volume of IDD data.  We have 10 TB of disk on our motherlode
clone machines and we are using approx. 6-8 TB for 20 days.  As IDD
data volumes go up, however, your disk space needs will also increase,
this is why I mention 15 TB instead of more.

I have attached the quote that the UMiami folks sent us back in 2013.
Of course, the prices listed for the class of hardware specified are
no longer valid!

Cheers,
