Dear Lazyweb:

Someone tell me which OS has the following set of features:

• Stable
• ZFS Support
• SATA Port Multiplier support

As far as I know there is support for both of those in FreeBSD, but the PMP code is buggy.

Linux has PMP support, but not ZFS (because of the GPL issues).

OS X supports both stably, as far as I know. But you need a mac.

Now if only someone could figure out how to hack linux's port multiplier code into FreeBSD, you'd be all set.

Mac OS X

I got curious about the OS X support as a Mac guy myself. Digging a little further:

* ZFS does not and will not have native support, but there is a longstanding port of unknown but presumably decent stability

* Port multiplier: "Answer hazy, try again later." This thread was the best I could find with light Googling; as of a few years ago at least some Macs didn't support it.

maybe...

Linux: has Sata port multiplier support, as of kernel 2.6 and above--
Linux: has ZFS support, using the FUSE project (not native to the kernel but is a module that can be implemented at startup)
Linux: mostly stable, can be fixed on the fly as problems arise and you are *more* than proficient in coding, thus for you it'd be a cakewalk, or piece of pie, depending on what you enjoy more ;)
Aside from that, YMMV, taken with a grain of salt, yes I said I'd never reply here again, but if I get flack for this, honestly, whatever- be well, hope you find what you are after and that it works well for you

oh, that list looks familiar...

i don't know about the recommended, but macos x is in the unrecommended list. ask me about it offline sometime if you want to hear a good rant. i have absolutely nothing nice to say about silicon image and their port multipliers.

however, if you want an express card controller, i have one you can have for free.

OpenSolaris can do it, but FreeBSD is probably the more sensible choice. If you hunt around you can find patches to allow port multiplier support, but I've heard rumors of deadlocks in some configurations. Perhaps in 8.0 the support is better -- 8.0-RELEASE is coming probably Q3, so trying a snapshot might be an ok idea.
