Sure, it is running on SanDisk Infiniflash HW. Each Drive BW while test is running was ~400 MB/s and iops is ~20K , 100% 4K random write. In case of 16 OSD test, it was 16 drive Infiniflash JBOF with 2 hosts attached to it. The hosts were HW zoned to 8 drives each. The entire box BW is limited to max 12GB/s read/write, when it is fully populated i.e 64 drives . Since it is 16 drives , box will give 16 X 400 MB/s = ~6.4 GB/s. 100% Read iops for this 16 drive box is ~800K and 100% write iops is ~300K iops. Drives were having separate partition for Bluestore data/wal/db.

What are the performance characteristics of the storage subsystem without Ceph?
