RE: When Does Microsoft Recommend Defrag of Exchange IS?
I don't think there is any such creature. Essentially you have 10% white space on your box. You are only going to reclaim 2GB of space by doing it now. What does he intend to do with this small amount of space? If you wait 3 months, is going to be better or worse, or what will it matter. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Derrick Stevenson Sent: Monday, September 10, 2001 11:24 AM To: Exchange Discussions Subject: When Does Microsoft Recommend Defrag of Exchange IS?

Re: When Does Microsoft Recommend Defrag of Exchange IS?
There is no such Microsoft recommendation. The decision as to when to do an offline defrag is purely the customer's decision. - Original Message - From: Derrick Stevenson [EMAIL PROTECTED] To: Exchange Discussions [EMAIL PROTECTED] Sent: Monday, September 10, 2001 1:23 PM Subject: When Does Microsoft Recommend Defrag of Exchange IS?

RE: When Does Microsoft Recommend Defrag of Exchange IS?
I don't know of a set ratio that MS recommends, I do believe the feedback that I remember seeing on this around here a while back was simply, why? I can say the only time in 3 years that I have ran a defrag was after our array went south, and that was only a matter of the DR procedures. Our DB is usually around 3-4 gig (small local gov) and our white space has ran anywhere from 50m to just over a gig. You are running just shy of 10%, where I usually run at about 15%. Again the question I would ask is why? Unless you need that extra 14gig of drive space for something else. Jeff Jeffrey R.

RE: When Does Microsoft Recommend Defrag of Exchange IS?
Derrick, just mention in your next conversation, in your most somber engineer voice, that the databases should be fluffy with white space rather than dense and defragged. fluffy is the word you're looking for. :) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Derrick Stevenson Sent: Monday, September 10, 2001 3:44 PM To: Exchange Discussions Subject: RE: When Does Microsoft Recommend Defrag of Exchange IS?

RE: When Does Microsoft Recommend Defrag of Exchange IS?
If E-mail reliability (aka - uptime) is paramount, the case is almost made for you. Do a simple cost/benefit analysis of taking the database off-line to defrag it. Cost = Downtime of Exchange server Benefit = 2Gb of additional free space (unless the server is low on space, benefit is almost 0) Eric On Mon, 10 Sep 2001 15:44:15 -0500, Exchange Discussions [EMAIL PROTECTED] wrote: To All That Replied: Thx 4 all the angles @ which I can approach my manager.

Wooho! -Original Message- From: Woodrick, Ed [mailto:[EMAIL PROTECTED]] Sent: Monday, September 10, 2001 2:13 PM To: Exchange Discussions Subject: RE: When Does Microsoft Recommend Defrag of Exchange IS? Derrick, I believe that the closest you will find a suggestion to be is if you delete a significant amount of content, therefore creating a significant amount of whitespace. When determining the amount of whitespace to delete at, it is probably much more important to look at trends instead of specific numbers. If you are staying well below the database size, and your transaction logs size don't indicate that your data transfer in and out of the store is that much, then I'd think about compacting the database. Note that defragmentation occurs nightly, is compaction that requires taking the server offline. 10% whitespace? No question that you do not need to compact your database.

RE: When Does Microsoft Recommend Defrag of Exchange IS?
Excellent approach Ed! For the past 2 months the white space has been in the 2-2.5GB range. So, there's no real danger of space consumption. Unless someone does find a TechNet article, I believe I now have plenty of reasoning points. These list serves are useful. :-) Thx All! _ Derrick Stevenson Sr. Technical Engineer Advisor mailto:[EMAIL PROTECTED] National Rural Electric Cooperative Association _ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin:[EMAIL PROTECTED]
