Hi list, It's probably something to discuss over coffee in Ede tomorrow but I'll ask anyway: what HBA is best suitable for Ceph nowadays? In an earlier thread I read some comments about some "dumb" HBAs running in IT mode but still being able to use cache on the HBA. Does it make sense? Or, is this dangerous similar to RAID solutions* without BBU? (On a side note, we're planning on not using SAS expanders any-more but to "wire" each individual disk e.g. using SFF8087 per four disks minimising risk of bus congestion and/or lock-ups.) Anyway, in short I'm curious about opinions on brand, type and configuration of HBA to choose. Cheers, Kees *: apologies for cursing. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
