Hi,

have here DSSV7 (lastest) running on a Dell R720 8c 3,3Ghz, 96GB memory, ESXi 7.0b.

There drives are Samsung 750GB SATA SSDs. The controller is a Dell PERC H710 Mini with batterie.
Have ran some benchmarks with Atto on a Win2016 VM (same image, moved between the datastores).

Results:

Same RAID5,
NFS Datastore: 60MB/sec-660MB/sec write, 69-927MB/sec read, avg. about 500MB/sec write, 700MB/sec read
iSCSI Datastore: 7-34MB/sec write, 54-684MB/sec read, avg. about 30MB/sec write, 600MB/sec read

iSCSI Setup on ESXi/DSS like: https://kb.open-e.com/dss-v7-iscsi-t...s-v7_3221.html

Any idea, how the find the bottleneck?

Thanks

Henri
