A lot of the research I’ve been doing lately has revealed that most NAS Server Admin’s today are not using a Hardware RAID controller anymore.
Instead, they are using a Host Bus Adapter (HBA) in place of the dedicated Hardware RAID Controller Card. This allows them to leverage their Server’s CPU to provide the computational power for a Software RAID, using a new Advanced File System called ZFS. ZFS of course has it’s own version of RAID called RAID-Z. I intend to use this for my main storage going forward, but I’ll have to order some new stuff, like the afore-mentioned HBA card to replace my PERC 6/i, as well as some new cables to feed the backplane as the old PERC 6/i used a different connector.
