Actually, the calculation is that it needs a GB of RAM for every
TB of
managed data.
How do you reckon this? Ie, what's the basic assumption(s) for the
statement?
Parity calculations for stripes or what? I don't follow.
I can't say I've ever heard any such like, so please do enlighten me!
It used to be written in the solarisinternals.com wiki - but I can't
seem to find it anymore.
ZFS is a moving target, in some ways, so the requirements may have
changed or are no longer that simple.
But it made sense in the early days, when SUN's thumper (X4500, 2*DC
Opteron, 48 disks, 16 GB RAM) more or less fit the requirements
perfectly.
cheers,
Rainer
