[ceph-users] Re: About erasure code for larger hdd

I'd start with 3+2, so you have one node left for recovery in case one fails. 6-node and 90 hdd per node sounds like a long recovery that needs to be tested for sure. On Mon, 9 Dec 2024 at 06:10, Phong Tran Thanh <tranphong079@gmail.com> wrote:

Hi community,

Please help with advice on selecting an erasure coding algorithm for a 6-node cluster with 540 OSDs. What would be the appropriate values for *k* and *m*? The cluster requires a high level of HA and consistent throughput.
