We had those things at work as fileservers, so no containers or anything fancy.

Sun salespeople tried to sell us the idea of "zfs filesystems are very cheap, you can create many of them, you don't need quota" (which ZFS didn't have at the time), which we tried out. It was abysmally slow. It was even slow with just one filesystem on it. We scrapped the whole idea, just put Linux on them and suddenly fileserver performance doubled. Which is something we weren't used to with older Solaris/Sparc/UFS or /VXFS systems.

We never tried another generation of those, and soon after Sun was bought by Oracle anyways.

I had a combination uh-oh/wow! moment back in those days when the hacked up NFS server I built on a Dell with Linux and XFS absolutely torched the Solaris and UFS system we'd been using for development. Yeah, it wasnt apples to apples. Yes, maybe ZFS would have helped. But XFS was proven at SGI and it was obvious that the business would save thousands overnight by moving to Linux on Dell instead of sticking with Sun E450s. That was the death knell for my time as a Solaris sysadmin, to be honest.

ZFS probably wouldn't have helped. One of my points is, ZFS was slower than UFS in our setup. And both where slower than Linux on the same hardware.
