Robert,
Regarding your note here:
http://www.gossamer-threads.com/lists/openstack/dev/30591#30591
You rightly said "If it is not in memory you will hit your disk with a lot of
extra reads."
If all data can't reside in memory - one option is to increase the memory on
nodes (expensive). Another is to use SSD instead of traditional spinning disks
(Also expensive if data volume is high). What are your thoughts on use of SSD
as a HDD caching device in the context of both Swift and Cinder in OpenStack?
It is cost effective and can be seamlessly deployed.
Look forward to hearing from you,
best,
S
