Hello! Is ICPv2 included in the plans for varnish 2.0?
No.
Our thinking on ICP in general is that a two-layer setup is a better
use of HW-resources.
It would be interesting to know a little more about how to configure
Varnish in a two-layer setup. I guess this would be of interest to others
deploying varnish as well.
Would such a two-layer setup be comparable to a squid cache hierarchy in
surrogate mode?
For instance, if you had four servers with equal hardware resources to
use as Varnish caches, how should these be optimally configured?
- A two-layer setup would mean a hierarchy with two siblings in
two layers.
- An one layer setup would mean four siblings in one layer.
If I understand this correctly, the two-layer setup would have a lower
mean time before failure, but a higher cache hit ratio, than the one layer
setup.
