 Dear Guys,

I would like to ask you abuot this kind of hw. raid card: Intel RS2BL040

Do you know, the 2.6.32 kernel does support this kind of hardware raid?

I know, it is not contain BBU in default, but support it and it is
recommended to use one.

 

(Anyway, in a recent server pveperf reports only ~100 FSYNC/SEC, which is
incredibely low (software raid1). Seems, even it is possible to use software
raid and the hdparm -tT shows high performance (even pveperf), but somehow
this only parameter significantly low and it is a bottleneck for the whole
system. )

 

Üdvözlettel / Kind regards

Pongrácz István
