2 raid controllers?

[bloodlet]

I have an old HP server that I need to add storage on. The current raid controller cant handle more than it does. Can I add a 2nd PCI controller and build an array, leave the crurrent PERC controller as the main bootup? Will I run into any issues? Please advise. The OS is 2003 server standard.

You should have no problems doing this. Many servers have more than one controller for either additional arrays or failover capabilities.

What about spanning arrays across 2 identical raid controllers...are there any controllers that are designed for this?

yes many controllers allow you to connect them together and have single array spanned across 2 controllers. Even cheapo rocket raid controllers have that feature.

wow that is cool (2 attached controllers), is there a name for this type of controller capability?

it depends on vendor highpoint calls it "Single RAID Cross Adapter Support"
Areca's version is "Multi-adapter support for large storage requirements"
so each vendor is calling it something else but most of the decent cards support it
