Flexible vs PCI array controllers

[PatrykW]

Hi everyone,

I'm wondering what could be the advantage of having 2 Smart Array controllers, for example an E208i-A + E208iP 

What are the possibile uses for a configuration such as this?

I was talking about this with a client that wants to use GlusterFS but i don't really know how it would work.

Hi,

you can connect more Disk Drives without using a SAS Expander.

You have more Read Cache (The E Modell have only Read Cache).

If you do a Software Raid 1  split to both Controllers, then one Controller can fail, without loss of Data access.

In practice, I prefer one controller because then I don't have two disk pools.
