Impact of Inceasing MAX MIF SiZE on SMS_INBOXES and Storage in Primary and CAS servers

[Kiran chandra B]

Impact of Inceasing MAX MIF SiZE on SMS_INBOXES and Storage - 
just wanted to check on increasing MIF size from default 5MB to 10MB on primary and CAS servers, what is impact? Do we need to increase storage of SMS drives and impact of processing data coming back to Inboxes.

Pls provide ur suggestion for this urgently

why exactly do you think you need to do this ?

On you CAS Nothing. On your Primary site, it will allow the HW inventory to be added to the db. Also keep in mind that this will REDUCE (yes reduce) network, CPU and IOPS on your clients and MP, site server as it will Stop the resync looping. Go strait to 50 MB, don't bother with anything smaller. 

Change the Maximum File Size of a MIF - Recast Software

Thanks for reply, I was getting this error and solution provided was to increase the MAX MIF SIZE, do you mean it will not need more storage if will increase MIF file Size limit, only will REDUCE network, CPU and IOPS on your clients and MP, site server as it will Stop the resync looping.

Well you DB size increase, yes it will but you will likely never notice it. And or you will not care as having the inventory is more important that the db size.

Thanks for all the info, as you mentioned increasing MIF size to 50MB -  will REDUCE (yes reduce) network, CPU and IOPS on your clients and MP, site server as it will Stop the resync looping does this mean clients will use more bandwidth to reduce network speed and increase N/W traffic, is it same effect if we set MIF size to 10MB from default 5MB

[GarthMJ]

It is the same affect BUT if you are going to change it to 10 MB why not go to the max that is can be? What problem will setting it to 10mb solve that 50 mb will not solve?  BTW, I'm finding that the avg full MIF is ~ 15mb these days, with AI data so....

Thanks for above info, Also wanted to check if we can estimate the increase to the DB? what is the size now and how much space on the drives where the DB file is?

I user 15-20mb per client + 2gb for the db itself. (#of clients * 20mb) + 2048 MB for db size. But honestly, the db size is not the issue, having the correct data is the issue and db grow within reason is more important.

can we do this change only on CAS server or on all primary servers also

As I says in the blog, you must do this on your primary and CAS servers.
