NetApp's customers resisting Clustered ONTAP transition

Re: CDOT fail

I'm in the middle of a 7-mode to cDOT transition, and it's not easy. But... once you've made it, the benefits really are there. It's just that the cost of the storage is still way too high. And for simple NFS only file shares, the new cDOT is *much* more complex and harder to do the simple things.

But don't get me wrong, this is the transition they needed to make, they just should have made it five years ago, and done it with more of a break IMHO, so that they could really encourage people to move.

Now you can snapmirror volumes from 7-mode to cDOT, it's not impossible like one of the posters said. Is it simple? Yes. Do you run into problems? Yes. I tried doing this over a WAN link and we ended up having to stop it because of major problems with volumes locking up. But for short term quick copies/migrations, it does work. And it might also be that the newer version we're on will have fixed those issues.

The other big issue which has been fixed with cDOT 8.3 is that you do NOT need to dedicate entire disks to the root aggregate and volume any more, they now spread that across multiple disk using that magic technology... partitions! This fixes a major issue lotso f people had, that on small systems, you lost alot of disk to core OS overhead. It's still not perfect, but it's better.

So on the whole, I'm happy with cDOT and I really like how I can setup virtial filers for seperate groups and consolidate stuff and yet not worry about someone bringing down other groups when they screw something up on thier Virtual Filer (SVM). It's liberating, sorta like early VMware/Xen/KVM was. IT's still rought around the edges, but it's getting more polished all the time.

Now they just need to bring down the price so as to encourage sales so they can amortize their sunk costs across as big a base as possible. Really, they can do this, it will just take time. And they need to in some ways also simplify their offerings and work hard to provide value again. Stop trying to be everything to everyone, just provide the best NFS/CIFS/iSCSI/FC storage they can, with emphasis on the first two like in the past.

SpaceX Dragon crew capsule in 'CHUTE ABORT drama – don't panic, no one died

John Stoffel

That second paragraph is bollocks!

I like how NASA holds everyone else to that high standard, but then relaxes it when it came to the shuttle. The first couple of test flights had ejection seats, but after that they were removed. This is what I don't like large solids for manned launches. A) you can only test fire them once, B) they're hard to shutdown when problems arise. With a liquid (or possibly a hybrid solid/lquid Oxidizer) you have more of a chance to shutdown cleanly.

Look at how various Saturn V launches had problems but kept going because they could just shutdown one of the engines. SpaceX had one like that too if I recall...

As did the shuttle, post booster seperation where they had one engine shutdown early and they just ran the other two longer to get into almost the correct orbit.

Good news for gamers who don't leave the house: SanDisk debuts 24/7 Extreme PRO SSD

John Stoffel

I agree, the longer warrantee now makes it much more likely that I would buy one of these for my home systems, as well as work systems. But it does come down to the number of writes in the specs, which I haven't touched yet.

Don't you all look at warrantee length when you buy spinning rust too? The extra money is well worth it when/if a drive dies 4 years down the road. You might argue that it will be obsolutete by then, but it probably will still be useful no matter what.

BlackBerry makes its devilish Android trickery official in OS update

John Stoffel

I've had a Z10 from quite early on, and now I'm also carrying an iPhone 5 and I have to say I prefer the screen size and feel of the Z10 over the iPhone. Somethings are better on the iPhone, but the Z10 gets alot right as well.

The soft keyboard on the Z10 is better, or at least I can type faster and more accurately on there than on the apple. I've got bigger hands, so I find the just a bit bigger Z10 a real advantage. I'd probably go Android otherwise because of the physical size I'd prefer to have.

I also like that I can expand my Z10 with an SDHC card for more storage room, as well as replac the battery with a new one or a spare if need be. And the iPhone's email is *horrible*. Maybe I'm dumb, but not being able to group emails by sender and quickly and easily select multiple emails at once is key, and the oiPhone (running iOS 7) just doesn't do that.

I do like iIOS7 though, it looks much better to my eye and seems to work quite well overall.

Prince Opteron unloads on AMD, Intel and the future of memory

John Stoffel

Wow, remembering the Encore Multimax...

Wow, this brings me back. My school brought in an Encore Multimax to reaplce a DEC-20 as the general computer for the school. 20 processors, 64mb of RAM. A real screamer! Cost us $250k at the time.

I helped move it in and it worked well with a bunch of DECstation 3100s as the front ends, replacing VT100/220s.

Three years later, we ditched it for $25k... talk about depreciation!

It was a pretty decent machine, watching compiles fly by with 'make -j 8' was cool.
