Can you utilize 2 RAID Cards to achieve better performance?

Hello, 

I'm in the mix of creating a 50 disk array on a RAID card (still choosing but it looks to be the PERC H710P mini) since i'm going to be doing this on a R720. 

I may have to buy a separate RAID card such as an LSI card that has external sas so I can connect my DAS setup. 

I was wondering is it possible to utilize 2 similar raid cards or it has to be 2 of the same brand? If so by utilizing 2 RAID controllers will you achieve better reads and write performance combining the two?

I don't think you have have 2 raid card work together and create one array. You can have 2 raid cards, and make different raid arrays.

 

But with 50 disks, I don't see a reason to, you should be fine with just one card, your likely to be disk or network lmiited anyways.

You planning hardware or software RAID..?

I'm choosing hardware raid since i'll be running EXSI.

Why does the hypervisor your choosing influence your choice of software vs hardware RAID?

 

I ran truenas under ESXi for years, and now still run it under proxmox... I personally think ZFS is the better option, but regardless of my opinion, ESXi doesn't need to dictate software vs hardware...
