I'm curious as to what the maximum real-world throughput of those arrays
is. And also what was making the storage controllers unhappy.

The 1.8GByte/sec mass storage write performance I mentioned upthread is
pretty much happening on "parts bin"" hardware without any tuning.

The 128TB file servers I was building 7.5 years ago (yikes!) do 700Mbyte/sec
I/O (averaged over a 24-hour period) and they cost under $3000 (not includ-
ing bare 8TB disk drives) to build with new parts back then.

I'm wondering how that compares with what HPE is doing. Obviously one
can build all-flash arrays of incredible speed (and price 8-) or low-cost arrays 
using low-performance shingled drives.
