Who's talking about "small and cheap" or NAS? That's the home market, not the commercial market.
If it has fewer than 12 drives in it, it's not a storage box worth mentioning here.
Btrfs is nowhere to be found when you get into real storage solutions. The NetApp, EMC, Veritas, Greenbytes market, not the home "2-drives in a box with an ethernet port" market.
You can spend a couple hundred grand for an iSCSI/FC box from NetApp or EMC. Or less for a Greenbytes box using ZFS+. Or less for a Solaris box using ZFS. Or even less for a custom white-box with OSol/FreeBSD using ZFS.
I've yet to see a single product in this area that boasts about using Linux and/or Btrfs.
Sure, maybe Linux has taken over the "2 drives in a box with an ethernet port" market. But who cares? That's not was enterprises, businesses (even medium-sized ones), or even school districts are looking at.
You specifically used the phrase 'turnkey' and started talking about FreeNAS and Nexenta probably because you know Solaris and ZFS aren't there at that end of the market, and it's more of a small business storage market these days.
Neither is ZFS. NetApp, EMC and Veritas are the only companies worth mentioning there and Sun with ZFS are merely bit-part players trying to get a piece of the action with something cheaper. They are irrelevant.
You're trying to create some 'enterprise storage market here that Solaris and ZFS are a part of and it just isn't there.
That's the small and cheap NAS market that you claim that we're not talking about where Solaris and ZFS are not present. It's all dominated by Linux systems.
You wouldn't. They use Linux and XFS, LVM and RAID generally. That will change with Btrfs. Linux is already there. It's pointless talking about Btrfs because it will appear by default.
Well, yes, that's what they are looking at because one of Sun's goals for ZFS was to make dynamic storage cheaper as storage hardware has got cheaper. Unfortunately for Sun they're caught somewhere in between NetApp, Veritas and EMC and all those smaller 4, 8 12 or more disk storage boxes from manufacturers that all run Linux, just like they were with PC hardware. That's probably why Sun hasn't done too well.

Is there? I must have blinked because I missed it.
The storage industry consists of established players using things like VxFX and clustered filesystems. Sun came late into the storage market with ZFS hoping to capture some of that established market share as a cheaper alternative, and they've had rather mixed success.
Hmmmm, so that's what you consider to be a 'storage industry'? I'm afraid installing Nexenta or FreeNAS yourself is not a storage industry.
All (and I mean all) of the 'turnkey', small and cheap commercial NAS and storage boxes I have seen use Linux and generally XFS as filesystem. Not a single one runs Solaris or ZFS. Btrfs already has a ready and established market that Linux itself is already in.
