Then there is a huge missunderstanding somewhere in the channel between you and me, or rather one of us is missing something awfully obvious: to me, it seems that you're missing the obvious thing that the RAID's performance, implemented with VxVM, will benefit from a powerful CPU.
Another thing that confused the hello outta me was your mentioning of (Adaptec) hardware RAID in your post.
But OK, now I un-confused myself somewhat. I agree with your points largely, but not totally. For example: if you have a Sun Fire V880 maxed out at 8 UltraSPARCs, adding more CPUs is not a viable option. But, fortunately, you can buy, for example, a T3 RAID fibrechannel RAID array, which will increase the overall performance of your system, if you are replacing a JBOD+VxVM or SDS.
BTW, I have been working with the latest incarnation of SDS (now called Sun Volume Manager) a lot, lately, and I have to warmly recommend it to you. It's not anymore the little brother of Veritas, and it has even some advantages. One of them is that it's free.

You're right. However, I understand that Sun is adressing the issue as we're talking?
They never stopped support for BeBox and Macs. The only thing is, the only supported macs are the PowerMacs with the 60x and PCI bus. You should check the HW compat list. In a way, it's the Macs that stopped being supported.
However, if you have a G3 or G4 daughterboard in one of those PowerMacs, BeOS will utilize them, with lots of speedy delight;->
BeOS doesn't run on anything less than Pentium MMX, by design. openbeos.org might change this, some day, but then that won't be called BeOS anymore.

Just a minute: 4 drive RAID 5, of which one was the hot spare? So you basically had 2 drives for data, only. That's not the most efficient RAID 5 setup one can imagine. In fact, the same utilization of drives you could have achieved with RAID 1+0, with the added benefit of much better performance than RAID 5.
OK, so these IDE RAIDs do have hot spare. Good to know. Is there a limit to how many hot spares you can have, and whether you can have more than one RAID (0 or 5) on one controller?
I have two comments: - you said you used a large 0+1 RAID. 12 drives. Well, you should know that 0+1 is much more sensitive to multiple drive failure than RAID 1+0. RAID 0+1 will lose all your data if only one drive in each stripe of the mirror fails! RAID 1+0 will survive any number of failed drives, in each mirror, as long as the two drives don't belong to the same mirrored pair.
- you mentioned having Veritas installed, but don't explain what it was actually used for. That may account, depending on the implementation, for the CPU usage.

IDE RAID Examined
·
· Score: 4, Insightful
I like reading the comments here, I am humble enough to know I can always learn something. But there's something I didn't see mentioned, in all these IDE RAID setups that people describe: can you have a hot spare disk? Hot spare is critical for data reliability. If you have a large RAID 5 or RAID 0+1 (not advised, always do 1+0, whenever possible), you can do the math and see how darn important it is to have the host spare.
What good it is to have a RAID 5 without a hot spare, when you can only guard against single drive failure? So, I really hope IDE RAID supports hot spare, otherwise I question the saity of mind of the admins who implement such solutions.
As for IDE vs SCSI drives, I have to say that I will always go with SCSI, as long as I am in a multuser environment where seek times are critical. Apparently (experience shows), if you put your database space on a RAID, seek times are critical for the performance of your application. In this context, I think this review/coparison would have benefitted from a real-life aplication's benchmarking, with a database hosted on the RAID.
No, it's with the ThinkPad (all models) trackpoint behaviour.
I saw what the problem is: they have it as "UNCONFIRMED". I didn't think it would be so hard to find a ThinkPad, but what do you know.
I tried to submit a notice that the bug still exists in 1.2.1, but I get the message from Bugzilla that only the owner, submitter or user with necessary privileges can do that. Strange again, since I am the submitter.
Too bad, because the behaviour is so irritating as to prevent me from using Mozilla on my laptop.
They have not fixed the bug I submitted (even though other people have confirmed it as they experience it, too), yet they have not listed it in the "Known problems".
What would be bigger news, as I've already said, is if a PC with Gnome were to be targetted at "Joe Dumbass Windows XP User." Not so likely....but hey we can always dream!
It's more likely than you make it seem, actually. It should become a reality with the Sun Linux boxen.
Umm... did you think this over, really seriously? I was a user of DigitalMe, and it made my Internet life a helluva easier. I could securely log into all of my services without having to know more than one password by heart. I could personalize most of those services, using just a browser and my account at DigitalMe. I had some messaging and e-mail options at disposal just as an added benefit. I all worked together. (Unfortunately, Novell discontinued the service, but that's their old illness: got a lot of cool technology, but incapable of making profit outta it.)
Nonetheless, I can clearly see the advantages the industry and private individuals would have from Liberty alliance's efforts. Note that I didn't even mention the B2B features that the Liberty Alliance is working on.
I don't know. I use Linux every day at work, and it was my choice.

I know a few other folks just like me, they use Linux every day, sometimes at home, too, but are not totally crazy about it.
I believe there is a certain number of realists among the Linux users. I think the percentage is higher than in the case of Mac users.

As another poster suggested: install Solaris. That way you'll also be able to install Solstice DiskSuite. I am sure you won't miss LVM.
Sure, it can't do RAID 5 in software, but it's a helluva flexible, and it does RAID 1 + 0 by default (unlike Veritas, which really seems to discourage RAID 1 + 0 in favor of 0 + 1). With the latest patches it also supports soft partitions,so you got much more than just 7 slices. Add the concept of disksets to the lot, and you see how SDS is rather nice.
You know what, I just realized I belong to the category of slackers that your post was intended to adress (I even run Slackware). I had this warm, fuzzy feeling that part of the Slashdot community cares about us, hopeless slackers.
