Both servers are identical:
2x Xeon E5-2620v4
128GB Ram
1x Intel 256G M.2 (OS)
1x Intel RS3DC080 backed by 6 Seagate ST3000NM0025 3TB SAS 12GB S ES 7200RPM 128MB in RAID 10 (Data)
1x Intel 400GB DC P3500 NVMe (L2 Cache)
2x Intel X550-T2 (one port from each for storage replication; one port from each for OS/VMs)
StarWind Virtual SAN v8.0.0 (Build 11456, [SwSAN], Win64)
I have an 8 TB single image file for data on the 8.2 TB RS3DC080 setup as LSFS in HA as an iSCSI device RAID with 300G L2 Cache on the P3500 NVMe.
D:\ = NVMe
E:\ = RS3DC080
V:\ = StarWind LSFS image on iSCSI
Attached are the diskspd results: NVMe:
