Sun Solaris, OpenSolaris "Sun's Ian Murdock gave a presentation about OpenSolaris at LugRadio Live this past weekend. He hopes to expose open source enthusiasts to unique Sun technologies by creating a cohesive distribution that will provide a complete environment that is adequate for day-to-day use. This will involve bringing together the Solaris operating system and a diverse assortment of open source community projects and "adding a package management system to hold all these pieces together," Murdock stated. The final release will take place in May and the distribution will adhere to a six-month release cycle, just like Fedora and Ubuntu."

I dont understand why you want you use your RAID controller? ZFS doesnt require RAID controller. ZFS can also fix problem that hardware raid can not handle. I trust ZFS more than a hardware raid.

ZFS detects errors within a few hours

ZFS can guarantee stuff no other can guarantee

I guess what Sun says about ZFS is about as reliable as what hardware RAID vendors says about their products.

ZFS fixed my desync 500GB mirror in under 13 seconds. Try that with a traditional RAID-1.

but zfs cant keep data with powerloss like a real hw raid. if my fileserver loses power all data in the raidcontroller will containpower and unwritten data can be written during next boot.

Doesn't guarantee all data makes it properly to the disks, though. Otherwise, people wouldn't talk about the RAID5 write hole (ZFS RAID doesn't have that, since we're at it).

For that matter:
1) Systems where it matters are using UPS backup.
2) Nothing stops you from not using the RAID functionality on a battery caching RAID controller.

ONLY if you hardware raid has a battery-backed cache...not likely any cheap VIA-based RAID solution is using a battery-backed cache.

I'll take ZFS any day over most RAID controllers...at least until you get into the high-end hardware RAID cards seemingly only affordable by businesses.

It is not that I want to use RAID. I want that Solaris talks to the controller, otherwise it doesn't see my hard-disk.

It complains that it is an unsupported controller, and installation stops.

As I said, I only have this problem with Solaris. ;)
