Is anyone trying Ceph clusters containing larger (4-8TB) SSD drives?
8TB SSDs are described here ( https://www.anandtech.com/show/16136/qlc-8tb-ssd-review-samsung-870-qvo-sabr... ) and make use QLC NAND flash memory to reach the costs and capacity. Currently, the 8TB Samsung 870 SSD is $800/ea at some online retail stores.
We have tested some of the 860QVOs and their performance was quite bad - they'd drop down somewhere around 24~36 MB/s for random I/O. We did not see such bevahiour for the 860/870EVOs though, which perform around 260~480MB/s. Best regards, Nico -- Sustainable and modern Infrastructures by ungleich.ch
