Ok - I'll give it a whirl in our dev/test environme
S3a exentsions within the RadosGW S3 API
implementation?
Plus - it seems like it's considered a "bad idea" to back Hadoop via S3 (and
indirectly Ceph via RGW) [3]; though not sure if the architectural differences
from Amazon's S3 implementation and the far superior Ceph make it m
ge for various large storage need platforms (eg
software and package repo/mirrors, etc...).
Thanks in advance for any input, thoughts, or pointers ...

hich brings me to a question ...
Are there any good documents out there that detail (preferably via a flow
chart/diagram or similar) how the various failure/recovery scenarios cause
"change" or "impact" to the cluster? I've seen very little in regards to
t
d then compare to faster sexier hardware. We do have a
lot of use cases for slower object services, where super high IOPS and
performance isn't critical; that’s our starting point for testing.

Some reason you are deploying an older version ?

For a high perf cluster - absolutely agree ... but I would suggest that
running the MONs as VMs has it's on performance challenges, to carefully
manage as well. If you are on oversubscribed hypervisors, you may end up
with the same exact issues with perf impacting the MONs. For a very small
non
cores/HTs than OSD disks, you
probably don't have a huge CPU issue to worry about (...probably...).

sses? What's the issue that prevents the MON from
listening on multiple IPs? Is the name hashed w/ the IP for internal auth
or referencing of some sort?
I'm new to Ceph - so just learning the ins-n-outs of how we can architect
this. Thanks!!
