P410 265MB+BBU poor write performance

[UCJSK]

Hi Guys,

my setup is as follows:

- HP ProLiant SE316M1 (=DL160 G6)

- 32 GB Ram

- P410 265MB+BBU (definetely enabled)

- 4x 1TB WD VelociRaptor (WDC WD1000DHTZ-0)

- Raid 1+0

- Windows Server 2012 Standard

After successfully installing Windows Server 2012 and all latest drivers, updates and firmwares I noticed that the write performance was incredibly poor. The BBU is installed an working correctly. R/W radio is set to 25/75. Does someone have an idea what could be wrong in my setup?

Thanks & regards

Hi,

From the specs given, I have two questions:

Is the WD VelociRaptor a HP model and is it compatible with this controller?

Second question, is Windows 2012 compatible with this server?

I would say NO to both the questions.

Coming to Read/Write ratio, refer to this document Configuring Arrays on HP Smart Array Controllers Reference Guide.

Try the following Read:write ratio
100:0
50:50

Good Luck

Thank You!
