It seems to me that FreeBSD probably would have a lot more support (and have it longer) for this stuff. Example equipment would be enclosures like this: - http://www.sonnettech.com/product/fusiond500p.html - http://www.sonnettech.com/product/fusiond500p-eseries.html - http://www.sonnettech.com/product/fusiond800raid.html Controller cards like this (or related, basically any eSATA card with at least 4 ports that supports port multipliers) - http://www.sonnettech.com/product/tempo_sata_x4p.html - http://www.sonnettech.com/product/tempo_sata_e4p.html I wouldn't plan on using the onboard RAID functions if I was using ZFS. I would export all the drives as JBOD to the OS. There are a lot of enclosures and a handful of controllers out there. It would be nice to know if FreeBSD has any possible options or not. Any help is appreciated. Thanks.
