Hello, (BTW, Nautilus 14.2.7 on Debian non-container.) We're about to purchase more OSD nodes for our cluster, but I have a couple questions about hardware choices. Our original nodes were 8 x 12TB SAS drives and a 1.6TB Samsung NVMe card for WAL, DB, etc. We chose the NVMe card for performance since it has an 8 lane PCIe interface. However, we're currently BlueFS spillovers. The Tyan chassis we are considering has the option of 4 x U.2 NVMe bays - each with 4 PCIe lanes, (and 8 SAS bays). It has occurred to me that I might stripe 4 1TB NVMe drives together to get much more space for WAL/DB and a net performance of 16 PCIe lanes. Any thoughts on this approach? Also, any thoughts/recommendations on 12TB OSD drives? For price/capacity this is a good size for us, but I'm wondering if my BlueFS spillovers are resulting from using drives that are too big. I also thought I might have seen some comments about cutting large drives into multiple OSDs - could that be? Thanks. -Dave -- Dave Hall Binghamton University kdhall@binghamton.edu
