Hi zusammen,
folgendes Server Setup:
Avago MEGA RAID SAS LSI 9361i16
SAS SSDs: 16x Samsung PM1643 1,9 TB
RAID Konfiguration: RAID 10 (14x, 2x Hot Spare)
Controller Info:

Schreiben:
Die generelle Schreibgeschwindigkeit sollte in der Theorie bei Rund 12.600 MB/s liegen, leider erreiche ich nur rund 2 GB/s.
In einer Windows VM habe ich testweise einmal eine 10 GB von a nach b kopiert und komme auf rund 900 MB/s.
(VirtiO Treiber sind installiert)
Kann hier jemand weiterhelfen?
