Hi Alex,
Just to know, what kind of backstore are you using whithin Storcium ? vdisk_fileio or vdisk_blockio ?
I see your agents can handle both : http://www.spinics.net/lists/

Hi Frédéric,
We use all of them, and NFS as well, which has been performing quite well. Vdisk_fileio is a bit dangerous in write cache mode. Also, for some reason, object size of 16MB for RBD does better with VMWare.
Storcium gives you a choice for each LUN. The challenge has been figuring out optimal workloads under highly varied use cases. I see better results with NVMe journals and write combining HBAs, e.g. Areca.
Regards,
Alex

If you currently are using Ceph+VMWare, or are exploring the option, I'd like some simple info from you: 1) Company 2) Current deployment size 3) Expected deployment growth 4) Integration method (or desired method) ex: iscsi, native, etc Just casting the net so we know who is interested and might want to help us shape and/or test things in the future if we can make it better. Thanks.Hi Patrick, We have Storcium certified with VMWare, and we use it ourselves: Ceph Hammer latest SCST redundant Pacemaker based delivery front ends - our agents are published on github EnhanceIO for read caching at delivery layer NFS v3, and iSCSI and FC delivery Our deployment size we use ourselves is 700 TB raw. Challenges are as others described, but HA and multi host access works fine courtesy of SCST. Write amplification is a challenge on spinning disks. Happy to share more.
