If so you may find that they have custom firmware which lowers their max transfer speed, we've seen that before. Also your firmware looks very old firmware, 07.15.08.00, we're running 20.00.04.00 which is still old, so you might want try updating.     Regards     Steve On 06/11/2017 22:37, Andrew Vylegzhanin wrote: > Hi! > > I have a problem with low transfer speed (150MB/sec instead of 600Mb/sec) > on SAS2 controller to SAS3 drive via SAS3 backplane. > > Hardware config is follows: > > Dell R720 box with Dell SAS HBA 6Gbps connected with Supermicro 45-bay JBOD > with two SAS-3 expanders (LSI SAS3x40 and LSI SAS3x36).
