If this is Skylake the 6 channel memory architecture lends itself better to configs such as 192GB (6 x 32) so yes even though 128GB is most likely sufficient
usng (6 x 16GB) might be too small. From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of Martin Verges Hello John, you don't need such a big CPU, save yourself some money with a 12c/24t and invest it in better / more disks. Same goes for memory, 128G would be enough. Why do you install 4x 25G NIC, hard disks won't be able to use that capacity? In addition, you can use the 2 disks for OSDs and not OS if you choose croit for system management meaning 10 more OSDs in your small cluster for better performance and a lot easier to manage. The best part of it, this feature comes with
our complete free version, so it is just a gain on your side! Try it out Please make sure to buy the right disks, there is a huge performance gap between 512e and 4Kn drives but near to no price difference. Bluestore does perform better then filestore in most environments, but as always depending on your specific
workload. I would not recommend to even considering a filestore osd anymore, instead buy the correct hardware for your use case and configure the cluster accordingly. -- Am Fr., 1. Feb. 2019 um 18:26 Uhr schrieb John Petrini <jpetrini@xxxxxxxxxxxx>:
