Syneto: Behold, blockheads – an all-flash array... based on ZFS A ZFS-based all-flash array? There's a thing to note in this block-focused all-flash array world. Europe-based Syneto has developed the product and it has updated its SMB-focused, ZFS-using Extreme 220 product. The Extreme 220 is a 2U x 24 hot-swap slot box with from 2TB to 144TB of SATA or SAS SSDs. That means 6TB SSDs are …

As long as btrfs still is using allocation structures insead free list forget about this.
Btrfs as well does not have anything like ZFS ARC.
So far each month is possible to spot many reports about different crashes of btrfs. In the same time it is really hard to find something about ZFS crashes.
I have both, but ZFS is far more stable - currently.
The biggest problem with ZFS is that it cannot be included in the Linux kernel, and so there is extra work to keep it out of tree.
BTRFS is probably usable for those of a less paranoid nature than I, but for now I will say ZFS is working fine.
P.
In other words they stuck some Illumos based distribution like OpenIndiana or SmartOS on top of commodity hardware, added a Web UI, and called it a day. ZFS deduplication is a notorious memory hog and not recommended for production use. Compression works very well, on the other hand.
As for BTRFS, it is at least 5 years behind in terms of maturity and robustness, ZFS is available for Linux as well, just not shipping together because it's license is not ideologically pure enough for the ayatollahs of GPL.
Perhaps they stuffed it with one or two TB of RAM. That would allow for a pretty large number of VM guests alongside with ZFS deduplication
In reality what I suspect is going on, they give client a switch to turn deduplication on, with a large warning on it "use only if you have this-and-this much ECC RAM installed"
Also this is very unlikely to be OpenSolaris derived work and much more likely is ZFS on Linux, because you cannot run "KVM hypervisor" they seem to advertise outside of Linux kernel

KVM has been fully ported to OpenSolaris.

OpenSolaris now can run Linux binaries without hypervisor like KVM

It is a Solaris derivitive. I tested it. UI looks good, but I broke my install and haven't looked at it for a couple of months. Each individual feature requires a PGP signed key, I would worry about my data locked into an array with an expired license if the company failed.
Oracle bought Greenbyte this summer, who rewrote the old memory hungry zfs dedupe engine. The greenbyte zfs dedupe engine will be used in the next solaris upgrade this year. It is fastest and best in class. It can dedupe 5,000 fat VDI virtual machines using 210 TB disk space, down to 4 TB. You can also activate compression in addition. ZFS dedupe will be a real killer when using VMs, and boot 6,000 vms in just five minutes or so.
