We have several clusters in the PB range that use dmcrypt. I can't speak to what it's performance detriment is to a non-dmcrypt cluster, but our clusters run just fine. I don't really understand the question though... Either you need dmcrypt for legal reasons in your business or you don't. If you don't then why use it?
Assuming I am understanding the question...
If there isn't too big a performance hit, it makes disk disposal (we expect disks to die, right?) much simpler.
OK. Thanks. But if I have a big volumes in TB size (10 TB volume) and writing/reading from the big volumes - will impact on performance like write and read speed? I surely see some impact on writing and read because - all chunks going to multiple OSD, where encryption requires, which may cause slow writes. Similarly for read also.
Thanks
