Every product they sell will die? That's absurd. I've been a NetApp customer and supported some reasonable size installations. The last thing anyone cared about, other than some techy admins, is WAFL. It's just not one of their selling points. Things like: 24/7 support, un-crashability, high performance NFS, world-wide resellers, *those* sell NetApps. If someone else (and guess what they have tons of competitors now!) sells pre-packaged servers that fulfill all of the above, ZFS may well be a great choice for the underlying FS, but it's not the One FS That Will Destroy NetApp, imho.

You can view the health reports (temperature etc.) that that telescope sent back via Iridium here.

There may be other tasties too -- I haven't dug too much.
