We have a two node Windows cluster which is attached to a SAN. We've made a RAID 5 on that SAN. The case is that Microsoft has suggested us doing a SAN defragmentation and we're hesitant. I'm quite sure that a defragmentation is very useful on a laptod, for instance, but not that much with a SAN system.
In the case that we do the defragmentation, what's the best application for that purpose?. Taking into account that we have over 5 TB of data and 1 TB of free space, how long will take to do the defragmentation?, do we have to stop any activity?.
Thank you very much.
