Current HP-VMware Images for Esxi 5.5 and 6 are containing the driver
scsi-hpvsa-5.5.0.100-1OEM.550.0.0.1331820.x86_64.vib
with this driver the RAID1 Performance is terrible low. (see table)
There are many hints on the net to downgrade the driver to
scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib
Even with this driver the IO Performance is not a s good as it should be. The reading speed
is much to low. Single Disk have write/read speed >150Mb/s (see table)
Is this problem known to HP development and are there any news on that topic ?
HP Microserver Gen 8/16GB/Vmware 5.5U3 on USB/2 x 3TB HD as RAID 1 on B120i
Just 1 VM running, no other running jobs, no rebuild etc. reading/writing 10GB
IO-Table(in Mb/s)
