Closing an EV index

[John_McCallum]

Hi

EV Version 8, SP3

Is there any "rule of thumb" for closing indices? As our index drives are filling up, we have created new indices on new drives. We now want to close some of the old indices to ensure that drives do not completely fill. All the old locations are of a similar size and not sure which ones would be most beneficial to close or is there no difference?.

Thanks

John

There isn't really a difference, assuming all indexes are for similarly active archives. If any of the indexes have grown large enough to make backups time-consuming, I recommend closing those first.

Remember that just because a location is closed, does not mean that the location will stop growing Any users that have active indexes in that location will continue to add to that index In other words if you have 1000 archives all with indexes being written to \index1, if you open \index2 and close \index2, you will only have new archives write to \index2 and the old archives will continue to write to \index1 Users archives would have to have their index roll over (an automatic process done by EV not likely to happen with User Archives). You can also manually move them through the vault admin console So a rule of thumb is to create at least 8 open index locations to evenly spread the archives and then when a location is getting to about 75% full, close it and then monitor it, move large archives when you need to and delete old archives when you can

Thanks for info. You talk about monitoring and then closing a location when 75% full. Are you saying that when a drive is 75% utilised, we should close all index locations on that drive and create new ones elsewhere? I intended closing 3 and creating 3 new ones on new drive - that is why I asked which ones to close.

Well let's say you have the following I:\ - 500GB drive and you have Five index locations all open I:\EV Indexes\Index1\ I:\EV Indexes\Index2\ I:\EV Indexes\Index3\ I:\EV Indexes\Index4\ I:\EV Indexes\Index5\ If you then divide the total drive space 500GB, divide it by the total amount of indexes (5 in this case) so now you have 5 indexes at 100GB each, so when a location becomes 75GB you turn close the location, giving it 25GB to grow, giving you time to move the bigger indexes to other locations

We have 4 indices on one 500Gb drive and they are all about the same size, 100Gb. So, looks like we should close them all, create 4 new ones on another drive and move one of them as well. Do you agree?

Wouldn't be a bad start, depending on how you run expiry, whether you delete archives for users that have left the company, whether you are goin to do large pst migration Projects down the line, you should monitor it closely if space is of a real concern to you
