Can iPhones and Smart Phones with Exchange clients slow down Exchange?

[stevenriz]

Hi everyone, I have this other thread going that we have had somewhat of a slowdown of our Exchange server recently and really don't know why.

-- It is definately an IO bottle neck so we are going to move the database and logs to an iSCSI array we have available here. My problem is I just don't know what happened and it seems to have happened all of a sudden. Our backups were running at 2000MB/min and are now down to about 300MB/min and I just don't know why.

I suddenly realized that we probably have a large number of new iPhones on the Exchange server as well as some smart phones with Exchange clients like Windows phones etc...

My first question is, is it possible that 20+ iPhones and some number of Windows smart phones and 20 Blackberries (BES server) contribute to a high disk IO? We have about 80 users altogether but more and more iPhone users everyday...

My second question is, is there a management server such as BES that we can set up and use to control the iPhones and Windows phones? Something that is policy based that can kill handsets if they are lost or stolen? I just feel it is getting out of control here.

thanks!!
Steve

The BES server access for a SINGLE blackberry device will introduce more IOPS than all of those iPhones and Windows Mobile phones combined. BES is horrible on storage, and easily introduces multiples of the IOPS of a standard user account (some will say up to 7x). Exchange Active Sync clients, like WinMo and iPhone, add a nearly immeasureable amount. Practically nothing. So little, in fact, that additional IOPS for EAS devices isn't even factored in when doing most storage designs.

Thanks Pat. I Wasn't aware of that. I still would like to at least better manage teh iphone population in case they are lost etc... I will check with our var to see what might be available. thanks again.

Stevenriz, you can use the Exchange ActiveSync Mobile Administration Web Tool, it works pretty well and allows you to remote wipe if the phone is lost
