Can a RAID array be moved from a HP P410i to a Dell Perc S100

I went through much pain with this, and the bottom line is that although the controller supports array expansion, Dell have disabled this in their Array Manager and they will not support it. If you replace the Dell driver with the LSI one (I think the controller is an LSI, though I wouldn't swear that it isn't an Adaptec) and use the LSI management software then you might be able to do it. However I would find this a scary business!

My solution was simply to create a new logical disk in the free space. This is completely safe and needs no reboots, though obviously it's clunkier having separate disks. If you really, really want a single partition then you'll have to backup then delete and recreate the array. Note that if your server has the Dell utility partition on it you need to be careful with partition imaging tools as you need to recreate the Dell utility partition or your server won't boot. I speak from (bitter) experience.

According to the Dell documentation, the H700 integrated supports 0,1,5,6,10,50,60 and the modular supports 0,1,5,6,10. According to the technical guidebook, they both support a maximum number of 16 raid volumes.

Typically, when ordering Dell equipment, the configuration options do not necessarily reflect all possible configurations. However, if it is not specified, your RAID will not come preconfigured.
