Hello, on HP Proliant DL320G5 I have raid1 with two HD 1TB Sata (on embedded raid controller) but when install vmware 4.1 I view two separate hard disks.
Is possible use with vmware raid1 (with embedded raid controller) ?
Thanks.

The RAID controller you have is a "software based raid" controller and is not supported for RAID in VMware ESX. This is why you are see-ing two different drives.

You may be able to install on a single drive, but it will not be RAID.

If you were to purchase a supported HP Smart Array controller, you would be able to use hardware RAID.

Just to confirm, you have actually enablled and configured raid 1 during POST before trying to install vmware?

I would expect that if done properly using hardware raid this would appear to vmware as your array rather than 2 disks.

I also not that this server is not on the VMware Hardware Compatibility list for VMware ESX/ESXi 4.1.

This could be due to the lack of supported storage controller. If you were to obtain a replacement storage controller, this installation may work for you for VMware ESX/ESXi 4.1.

This could be caused by a couple of things.
Firstly are you sure you have configured a raid 1(mirror) via F8 as the server boots?
If you are sure then the answer is the raid controller is not a true hardware raid controller. It requires a driver to access and manage the raid.
I though DL320g5 would have a P400 controller?

Check the harware compatability list on the VMWare site.

The storage controller is not supported by VMware or is the server for this very reason.

DL320 almost 100 series stuff - http://h18000.www1.hp.com/products/quickspecs/12572_na/12572_na.HTML - Intel® 82801GR Integrated Serial ATA Host Controller is what you get by default.

Yes, on boot with F8 I have configured raid.
OK I understood that on this machine there is a software RAID controller that I cannot use with VMware, so the only solution to use the RAID (on this HP model) is to buy a new controller raird hardware.
is just ?
Thanks.

Yes, ideally a model supported by VMware
