Re: [ceph-users] Recomendations for building 1PB RadosGW with Erasure Code

You should look at a 60 bay 4U chassis like a Cisco UCS C3260. We run 4 systems at 56x6tB with dual E5-2660 v2 and 256gb ram. Performance is excellent. I would recommend a cache tier for sure if your data is busy for reads. Tyler Bishop Chief Technical Officer 513-299-7108 x10

[ceph-users] Performance Testing of CEPH on ARM MicroServer

For most of you CEPH on ARMv7 might not sound good. This is our setup and our FIO testing report. I am not able to understand …. 1) Are these results good or bad 2) Write is much better than read, where as read should be better. Hardware: 8 x ARMv7 MicroServer with 4 x 10G Uplink Each

[ceph-users] pg repair behavior? (Was: Re: getting rid of misplaced objects)

Hi Bryan, You were right: we’ve modified our PG weights a little (from 1 to around 0.85 on some OSDs) and once I’ve changed them back to 1, the remapped PGs and misplaced objects were gone. So thank you for the tip. For the inconsistent ones and scrub errors, I’m a little wary to use pg repair
