Aha. So, you should have 76-152 GiB of disk cache on a few fast disks, if
you can afford that... along with a few gigs fo ram.

don't put too much of cache on one disk, it can slow you down. You can start
with e.g. 15GiB and increase by time, until you'll notice increase fo
response times. In such case, keep the L1 on 128.

Exactly, and vice versa. If they can connect to each other. And, if they are
not behind slow links, although it's probably they are (otherwise there
would be no need for 3 caches, right?)
