You could use vmtouch to drop the specific directory from cache. It has the
ability to evict directories/files from memory.

One thing that jumps out at me is using the S3700 for OS but the S3500 for
journals. I would use the S3700 for journals and S3500 for the OS. Looks pretty
good other than that!

What about the Intel DC S3500 instead of the DC S3700?

Hey everyone, loving Ceph so far!
We are looking to role out a Ceph cluster with all SSD's. Our application is
around 30% writes and 70% reads random IO. The plan is to start with roughly 8
servers with 8 800GB Intel DC S3500's per server. I wanted to get some input on
the use of the DC S3500.
on to have that much ram provided to a hosted client so we will be
forced down the SSD path.
Going to starting digging through the archives on how to best calculate some
base numbers to work off of. If anyone has any tips or suggestions, throw them
my way!
Thanks,
