Yea, the kernel for the "proprietary OS" is a BSD microkernel. The NFS code, came from Sun, the guys who designed it. Netapps licensed it from them. The engineers that work there at netapps, a lot came from Sun and hard drive manufactures. Oh, and I got my Netapps from one of the Dot.Coms that went bust, so I paid maybe an 8th of what it cost to purchase the same model, new. Did I mention Netapps is reliable? I showed up for work one morning and there's a hard drive sitting on my desk when I show up. Receptionist tells me Netapps overnighted it to me becuase a drive failed last night. > > Who told you that you have to spend hundreds of thousands of dollars on a > redundant SAN and software?

Have you check the prices for a SAN switch and JDOB enclosures, let alone an FCAL cards.. globalfilesystem.org, has been replaced with someone who appears to have either purchased GFS or has assumed sole responsibility for it.. Is it still GPL? GFS isn't ready for production use, too immature, and there isn't any ports for BSD (not completed anyway..). ;) Let alone the global locking issues that plagued it..

And they're not Linux-specific. Enough said. Really? NFS has been a God send in this shop and for every admin before me here. Linux NFS client and server is immature code. Period. Slow and buggy, IMO, like much Linux software, again, IMO. I'm not saying I don't run Linux, ever, it does have it's place. So, IMO, I like NFS, it's a godsend, it's saved my ass time after time.
