Hallo Simon,I am also about to buy some new hardware and for SATA ~400GB I was considering Micron 5200 MAX, rated at 5 DWPD, for journaling/FSmetadata.
Is anyone using such drives, and to what degree of satisfaction? Thanks Fulvio -------- Original Message -------- Subject: Re: SSD recommendation From: Simon Ironside <sironside@xxxxxxxxxxxxx> To: ceph-users@xxxxxxxxxxxxxx Date: 5/31/2018 2:36 PM
It looks like the choices available to me in the SATA ~400GB and 3 DWPD over 5 years range pretty much boils down to just the Intel DC S4600 and the Samsung SM863a options anyway. Since David Herselman's thread has put me off Intels I think I'll go with the Samsungs.Regards, Simon.

I was going to use 480GB Intel DC S4600 SSDs as either Journal devices for Filestore and/or DB/WAL for Bluestore spinning disk OSDs until I saw David Herselman's "Many concurrent drive failures" thread which has given me the fear.What's the current go to for Journal and/or DB/WAL SSDs if not the S4600?I'm planning on using AMD EPYC based Supermicros for OSD nodes with 3x 10TB SAS 7.2k to each SSD with 10gig networking. Happy to provide more info here if it's useful.Thanks, Simon. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com_______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
