Can I install larger hard drives in my server to replace the smaller hard drives in a RAID 5 configuration?

Assuming your controller supports drive expansion. You need to tell us what server make and model. Some servers don't support drive expansion. If it does, you can just swap the drive, one drive at a time. Allow a few hours for the drive to be completely rebuilt. You can check your controller Management Software for the rebuild status.
After you have done with the drive swapping, you need to get in the server management and expand your logical drive to the new larger size.
You then use diskpart to expand your partition to the new size. Diskpart will not work on the OS or system partition so if your exchange is running on other than C: you can do it. Otherwise, use third party software to expand partition (Paragon Parition manager, Acronis....)

I attached the Device Manager view of the Exchange server so it does have an Integrated RAID controller. The server is a DELL Poweredge 2900 and the service tag is F6Z72C1 so you can look up the specs. How do I access the server management and expand the drives to the new drives? Please provide me with a step by step procedure. Also, the Exchange configuration and settings are on drive E and not drive C which is the OS.

Thanks

Sorry...I forgot to attach the device manager settings.

I know HP does. In the past, Dell does not support drive expansion, but you can add more drives in the array. I am not sure if they do now. Please contact Dell support to clarify it before tackle your task.

This Dell spec does not metion the drive expansion so you may want to confirm with Dell support rep.

So do you know if this Dell model has the drive expansion utility because I do need to update these hard drives or what utility do you suggest?

No, you misunderstood me. There is no such utility to support Dell expansion. Plus, the spec does not tell me it supports that. Perc controller does not support drive expasion in the past. I need you to contact Dell support to ask them whether or not this server model supports drive expansion. If it does not, you can only add more space by adding more drives, not swapping the drive as the plan. Adding more drives, you need to have available room to do it. You should not pay anything for calling Dell support. Give them the service tag above.  1-800-624-9896

OK. Thanks

I contacted DELL and they said that I would have install new hard drives and reconfigure the server from scratch. I do not want to configure the server from scratch and would like to just install larger hard drives so any other recommendations would be apprecaited.

Thanks
