Thanks a lot Adam, it was an error typo, the 3700 are for the journals and the 3500 for the OS. Any special crush algorithm configuration for IB and for the mix of SSD and SATA OSD daemons?
Thanks in advance,
German

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!From: "German Anders" <ganders@xxxxxxxxxxxx>
