Yes I'm planning to use only 60% - 70% of my disks and pools like buckets.index doesn't grow too much and don't need much space! I'm just trying to make this pool faster because I see it sometimes needs 1Milion iops and I think NVME is a good option for this pool. But finding a good datacenter NVME in low space is too hard :( On Mon, Sep 14, 2020 at 7:32 PM Martin Verges <martin.verges@croit.io> wrote:
Hello,
Please keep in mind that you can have significant operational problems if you choose too small OSDs. Sometimes your OSDs require >40G for osdmaps/pgmaps/... and the smaller you OSD, the more likely it will be a problem as Ceph is totally unable to deal with full disks and break apart.

Thanks for the sheet. I need a low space disk for my use case (around 240GB). Do you have any suggestions with M.2 and capacitors?

and send me the results if you get one :))

I want to have a separate disk for buckets index pool and all of my server bays are full and I should use m2 storage devices. Also the bucket index doesn't need much space so I plan to have a 6x device with replica 3 for it. Each disk could be 240GB to not waste space but there is no enterprise nvme disk in this space! Do you have any recommendations? On Sun, Sep 13, 2020 at 10:17 PM Виталий Филиппов <vitalif@yourcmc.ru> wrote:
Easy, 883 has capacitors and 970 evo doesn't 13 сентября 2020 г. 0:57:43 GMT+03:00, Seena Fallah < seenafallah@gmail.com> пишет:
Hi. How do you say 883DCT is faster than 970 EVO? I saw the specifications and 970 EVO has higher IOPS than 883DCT! Can you please tell why 970 EVO act lower than 883DCT?
