Diskeeper pros and cons

Mike Poole_1 — Wed, 26 Jul 2006 13:13:40 GMT

Alpha DS10 running 7.3-2

We always had diskeeper on the old 1200 with no problems but do we still need to put it on our new ds10?

Advantages and disadvantages?

DS10 runs a StorageWorks RAID 5 rack for data, does this matter?

In short do we need diskeeper?

Thanks

If you want to keep your disk performance at an accetable level, then either Diskeeper or DFG from HP, should be used.
If you already have a license for Diskeeper then I would say keep it. Saves the cost of buying another license.
If you decide to not use either product then expect your DS10 to start performing like your old 1200.

Like so many other things in the world, "It depends" for various values of depends. If your application creates and deletes multiple files, a product like diskeeper can benefit and reduce longer term maintenance. If you can use large files, set large extents or primarily do read I/O on mostly static files it can less of an issue.

If I had a license available and it didn't conflict with my applications, I'd make sure it was installed.

Use the free reporting in diskeeper or DFU to check that fragmentation is occuring.

Collect performance data to see if fragmentation is actually causing a problem.

No point in spending the money on diskkeeper unless there is a problem.

Mike,

from your Forum Profile:

I have assigned points to 10 of 25 responses to my questions.

Maybe you can find some time to do some assigning?

http://forums1.itrc.hp.com/service/forums/helptips.do?#33

Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption "My Question(s)" you will find "questions or topics with unassigned points " Clicking that will give all, and only, your questions that still have unassigned postings.

Thanks on behalf of your Forum colleagues.

PS. - nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before - please do not take offence - none is intended!

Proost.

Have one on me.

Sorry about that guys!

I always try to assign points and thought I had done so but must not have hit 'submit'.

I appreciate the help!
