Tøft!

 

Jeg fant en kommentar fra osnews til en test av Solaris 9 som jeg synes er så artig at jeg poster den her. Siste avsnittet er spesielt interessant.

 

 

 

Despite suffering a big bump during the BSD->SYSV (Solaris 1.x to 2.x, SunOS 4.x->5.x), Solaris *IS* Unix. It *IS* NFS. It is quintessential UNIX. I've seen this OS deployed en masse. Diskless workstations, common image environments, extremely high performance NFS (even before Netapp existed.)

 

I have used Solaris x86 for three years on the CVS/NFS/SMB/DNS server at one of my clients. Never patched it ONCE. The only time it has ever been shut off is to MOVE it in the rack to another location.

 

UFS+Logging. Rock solid file system. Coherent. Well documented. Automounter that actually works.

 

You see, if you get hardware that it supports, it runs rock solid. If you bring a lot of trash hardware to it, it doesn't like it. Its not designed to be accommodating, its designed to work.

 

Using it as a gnome desktop is counter to its primary purpose. A high performance network server. As far as I can tell it is exactly that. Plus you can rollback updates, it is supported VERY well on a quarterly basis, and gets basically daily/weekly Recommended rollups.

 

Solaris is trick down. It is meant to run on huge machines, and then trickles down to the low end. Responsiveness to Mozilla is NOT a design goal. Sorry.

 

Ballmer was once overheard saying to Gates that MSFT was lucky that the "wrong UNIX" ended up on top. Linux. If you ever had to deploy a ton of a hardware, you might understand what he means. Nothing beats good hardware/software integrations. Really. It is not about 3DMark or how good your SPEC_FP and SPEC_INT are. There is a lot more to it than that. It is about quality support, great software discipline, coherence with itself and good documentation.

 

I have adminned a number of Unix in my stay on Earth. I must say, I have a love for FreeBSD and even have a Solaris 1.x box running (4.1.4) because that to me is Unix. But after the evil was hashed out of Solaris 2.x (2.5.1/2.6 was the turning point), it is always good to sit down at a Solaris box. Take a survey of uptimes on fairly busy machines and you'll see.

 

Also, read the Linux Kernel Mailing List. Just read it. It is classic bazaar mentality. I think its going to catch up with them in the end. Too much going on at once. Solaris and FreeBSD represent the Cathedral, a well built and architected system. You do feel the difference when using them all for various purposes.

 

I am literally dying to see the Opteron Solaris 10 native port. Solaris 10 has TCP offload (ever seen Linux abuse CPU with 2 or more gigabit network cards going at once?). It will have ZFS, a commercial grade filesystem. It will have "flick of a switch" Trusted Solaris. The only problem with Opteron boxes right now is they don't have OBP. Real debugging. Rational products for Solaris are great (Purify). DTrace is coming to enhance this as well.

 

Don't get me wrong, Linux has uses. I will always consider Windows and OS X worth paying for, and Linux not worth paying for. Linux's only allure that it could be downloaded and used for free. Barring that, it is useless to me. Even RedHat Enterprise Taroon 3.0 or whatever cant convince me of this. I must have access to Sunsolve. It's worth every penny. When RedHat stopped giving up2date for free, I immediately started moving away from it wherever possible. Why deal with Linux with Solaris is free? Why?

 

Also, DUMP actually works on UFS - well. To quote Linus on dump:"

"Note that I think all these arguments are fairly bogus. Doing things like "dump" on a live filesystem is stupid and dangerous (in my opinion it is stupid and dangerous to use "dump" at _all_, but that's a whole 'nother discussion in itself), and there really are no valid uses for opening a block device that is already mounted. More importantly, I don't think anybody actually does."

 

Great "boss". Real professional. Dump is stupid and colloquial expression such as "'nother." This man also believes Linux will unseat OS X and Windows and does basically desktop changes to the kernel while leaving scaled and server performance languishing, something RedHat and SuSE have to break their backs patching the thing wildly to even get it to be competitive.

 

I can only say this. I honestly believe that Linux is the best thing that ever happened to MSFT. Check out how much money they have made while Linux has been "destroying" them. Tons. Its psychotic that for the price of being a bit more traditional to configure people don't use Solaris and Solaris x86 more often. They pay the price and won't tell you how.

 

It also must be noted that Sun holds the world record on supporting Linux. RedHat 6.2 is roughly what Cobalt OS is for the RaQ4. The fact something that old is still supported is wonderful! I have several clients still using that "junk" just fine.

 

So, if you come and complain about Solaris or FreeBSD because it doesn't have wizards and requires you to know what you are doing to use it (just like a 747 has a very, very HIGHLY trained Pilot), go somewhere else. Preferably, get OS X and Windows and leave Unix to the people who like it for what it is, not what it could be in a Tele-tubby world. I don't care about a USB storage key working. I care about NFS working perfectly, I care about support. I care about uptime. I care about documentation. I care about things being coherent. I care about the fact that the discipline that a standards based platform like FreeBSD and Solaris force developers to make code that tends to be more easily ported. The development tools for Solaris are not free, rather they are expensive, but they are worth it. Every penny.
