Hi all, (I asked this on the Proxmox forums, but I think it may be more appropriate here.)
In your practical experience, when I choose new hardware for a cluster, is there any noticable difference between using SATA or SAS drives. I know SAS drives can have a 12Gb/s interface and I think SATA can only do 6Gb/s, but in my experience the drives themselves can't write at 12Gb/s anyway, so it makes little if any difference. I use a combination of SSD's and SAS drives in my current cluster (in different ceph pools), but I suspect that if I choose SATA enterprise class drives for this project, it will get the same level of performance. I think with ceph the hard error rate of drives becomes less relevant that if I had used some level of RAID. Also, if I go with SATA, I can use AMD Epyc processors (and I don't want to use a different supplier), which gives me a lot of extra cores per unit at a lesser price, which of course all adds up to a better deal in the end. I'd like to specifically hear from you what your experience is in this regard. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
