Hi,

I have HP Proliant ML310e G8 server with B120i controller (no FBWC).
HP 2TB 6G SATA 7.2k 3.5in NHP MDL HDD costs $550
Western Digital RE4 2000GB 64MB cache costs $200

I'm going to buy 2x2TB WD RE4 drives and build mirror. I love HP's iLO and array configuration utility due to failure prevent notifications.


Do you prefer Windows server 2008 mirror, or B120i mirror? And why..


Regards,
Jarda

B120i mirror for myself.  The less I have to rely on the OS performing mirroring tasks, the better.

The controller has better firmware, but in grand scheme of things it will not give you all the functionality with the non-HP disks.  

I would personally go with native Win8 mirroring against this controller since you have non-HP drives.  

This controller doesn't have dedicated CPU or RAM so all the work will still be done by your local CPU.  Overhead with mirroring is near zero, BUT with native windows mirroring, you can  let the O/S use more ram as cache buffers which could result in better performance.

But understand you need to use a non-RAID vanilla SATA controller if you want the O/S to do all the work.  Using that controller with software mirroring won't buy you anything and will actually result in more overhead because that controller will still virtualize the disks.

Hi dlethe,

It is exactly what I wanted to know. Unfortunately I have no Win8, but old Win 2008 server.
If I use B120i controller, HP iLO will see the drives and will check their health. Vanilla SATA will not.

Performance is not as important as reliability..

Many thanks!
