RAID 5 or RAID 0+1

[Guest MarcusB]

We have 3 file servers running windows 2003 and 2008 on HP proliant

servers. We need more disks in arrays. We have been using so far RAID 0+1.

Is it possible to add extra disk to RAID 0+1 array and extend the size

of the existing logical drive? Or we need to change to RAID 5 level.

 

We have know two RAID 0+1 arrays:

 

One array:

500 GB SATA disk

500 GB SATA disk

 

Second Arrays:

1TB SATA disk

1TB SATA disk

 

 

Can we add 4 1TB disks (2 to each array) and extend the logical drive size?

 

 

We have Smart Array controlers P800 on all our servers
