That clears my concern of the redundancy for your configuration.
Well, there's isnt a Dell test done so far with your configuration, 9 Logical Drives, includes 8 x RAID0 arrays. Although the specification stated it can support up to 16 Logical Drive per Disk Group, i believe it can support, but in terms of performance, I have to say it is going for a ride.
Perhaps if you do find a performance issue, you can always add on another H710p.
Thanks. Actually my exchange data has 3 copies in 3 separate servers for redundancy. What my concern is my raid configuration may take too much toll on the H710p performance since I am using it for 1 x Raid-1 and 8 x Raid-0 arrays. Is H710p able to handle the load in this kind of configuration?
Actually so far I have not seen any issue but I just want to know if this is the optimum and recommended design.

Hi Neil,
It's great that you have a good hardware there. Making sure data and operating system is on a seperate RAID Logical Drive.
Talking about performance and durability, we'll have to understand the needs and must of a server to be using RAID 0.
Performance of RAID0 is some what better than RAID1, due to it's writing speed. (Reference: http://i.dell.com/sites/doccontent/shared-content/data-sheets/Documents/perc-technical-guidebook.pdf). But! You are using it as an Exchange, there will not be any redundancy to your data, once a hard drive failes, all data will be corrupted.
Here are some white papers on how to utilize the PERC card in terms of performance, durability and redundancy:
