The following graph shows how split I/Os are basically eliminated during a backup of a defragged file. It also shows the overall massive reduction in backup times.
 


  and yes it happens on a SAN (I welcome any proof to the contrary).

DBMT still creates fragmented NSF files on volumes that are fragmented
Thu, Apr 6th 2017 8:12p   Adam Osborne
On a busy server Compact -C fragments NSF files left, right and center. It sprays bits of the file all over the place. The only thing we have seen in Domino that does a worse job are full text indexes. As previously discussed and referenced by others and IBM, DBMT does a much better job. It tries to create a contiguous NSF file, but it can ONLY do that it the freespace on the server is not highly fragmented, and the only way that is going to happen is if you have taken steps to keep it in sha

Virtualizing Domino is NOT a "Get Out Of Jail Free" card
Thu, Mar 30th 2017 7:49p   Adam Osborne
Further to yesterday's blog we wanted to point out that recently VMware updated their latest documentation for VSphere 6.5, included is the recommendation to "Defragment the file system on all guests" to enhance Disk I/O performance. It is so often not understood that fragmentation in the virtualized environment can have a devastating impact on Domino server performance and also the O/S, and yep, we see this a LOT. This negative impact happens because as far as the Guest O/S (Windows) is co

A simple way to reduce backup times by 55%
Wed, Mar 29th 2017 9:26a   Adam Osborne
Last week DDO went into action at an Australian Coal mining organisation. The server was a mess, with exceptionally long backup times. It is a VM, running on a high powered SAN, but none of that matters, because if Windows sees fragmentation it acts accordingly, it slows down and in this case was issuing millions of additional I/Os to get backups done. DDO ran and optimised the files. In the chart below you can see the positive effect of removing 742,289 fragments from just 144 databases. Back

How healthy are your Domino System Databases?
Mon, Mar 27th 2017 9:20p   Adam Osborne
Are the System Databases on your Domino servers optimized and healthy? You know, the really important ones that seem to never get maintenance, log.nsf, names.nsf, mailjrn.nsf etc, are they getting huge, sluggish to open, slow to backup, wasting GB of disk space? DDO makes this often never done Domino and database maintenance as simple as ticking a few boxes, set and forget,. If this is scheduled once a week the difference it makes to Domino is quite amazing. Here are some screen shots from a c

The easiest way to enable Feature Pack 8 View Separation
Mon, Mar 20th 2017 1:17a   Adam Osborne
In this 2 minute video, we will show how to use DDO to: - Enable Feature Pack 8 View Separation (NIFNSF) with a single selection - Direct the View NDX files into their own directory - Schedule View Separation for all Mail 9 databases - Schedule a Domino restart at 12:05 am to enable View Separation. Just for good measure, we'll run DBMT over all the System Databases at the same time. - Schedule DBMT to run at 2:30 am for 2 hours, during which View separation will occur on Mail 9 databases. On

DBMT Optimizations in DDO - real world example

Further to my previous post on "DBMT Optimizations in DDO that can reduce its workload by over 90%" here is a real world screen shot of what is happening at one of our clients. Now that's optimization. Why not try DDO for yourself with a free 30 day trial?

DBMT Optimizations in DDO that can reduce its workload by over 90%
Thu, Dec 8th 2016 12:23a   Adam Osborne
DDO includes three optimizations to DBMT that make a dramatic difference in its workload: The first and most powerful setting is the “Only Compact when Freespace exceeds” fields on the Optimization Schedule. By setting this field a database can only become a candidate for DBMT compacting when the freespace within it exceed the amount specified. This avoids potentially processing hundreds of database where little, or no, freespace can be recovered. This dramatically reduces DBMT processin

What are the stages of optimization in DDO?
Fri, Dec 2nd 2016 3:16a   Adam Osborne
One of the great features of DDO is how it works through its optimization stages automatically to ensure you get the best 'bang for buck' from your Domino server. The first stage is ensuring database properties on databases inheriting design from the mail template (or other identified templates) are set correctly. Any databases out of line are quickly put back into line. Stage two optimization ensures databases that need to have DAOS applied, have it. Any new databases created based on the i

New product - The Domino Database Optimizer – DDO.
Thu, Dec 1st 2016 4:32a   Adam Osborne
We are delighted to announce the general availability of our new product - The Domino Database Optimizer – DDO. The DDO combines the power of DBMT, with the intelligence of an inbuilt configuration tuner while also integrating everything we’ve learned developing Defrag.NSF. We’ve wrapped it in a single application, with a super easy to use user interface and scheduler. It is designed to work on all types of storage systems from direct attached, SSD, NSA, SAN or virtual.
