Hi, I have inherited an Exchange 2010 SP1/Enterprise Vault V9.0 environment. Will upgrading to Exchange 2010 SP2 cause any issues? Are there any updates I need to apply to Enterprise Vault before applying this Exchange SP?
I was in the process of checking the throttling policy for BES and could see a second policy for Enterprise Vault. I have researched this to check if the previous consultant has followed best practice and I just want to clarify this. From research I see there is a ‘SetEVThrottlingPolicy.ps1’ script (http://www.symantec.com/business/support/index?page=content&id=TECH156775) which restricts the following: RCAMaxConcurrency. The previous article suggests throttling the following manually: Set-ThrottlingPolicy -Identity EnterpriseVault_D0F41A15-9E91-D111-84E6-0000F877D428 -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null
In the current throttling policy, the following are set (I have removed confidential information and settings of $null), so clearly the above hasn’t been applied:
AnonymousMaxConcurrency : 1
EASMaxConcurrency : 10
EASMaxDevices : 10
EWSMaxConcurrency : 10
EWSPercentTimeInAD : 50
EWSPercentTimeInCAS : 90
EWSPercentTimeInMailboxRPC : 60
EWSMaxSubscriptions : 5000
EWSFastSearchTimeoutInSeconds : 60
EWSFindCountLimit : 1000
OWAMaxConcurrency : 5
OWAPercentTimeInAD : 30
OWAPercentTimeInCAS : 150
OWAPercentTimeInMailboxRPC : 150
POPMaxConcurrency : 20
PowerShellMaxConcurrency : 18
RCAMaxConcurrency : 100
RCAPercentTimeInAD : 5
RCAPercentTimeInCAS : 205
RCAPercentTimeInMailboxRPC : 200
CPAMaxConcurrency : 20
CPAPercentTimeInCAS : 205
CPAPercentTimeInMailboxRPC : 200
CPUStartPercent : 75
ExchangeVersion : 0.10 (14.0.100.0)
Do I need to make the suggested changes? What is the impact if I do/don’t make the changes? I just want to make sure I follow best practice.
Thanks for the advice.
Solved! Go to Solution.

if you actually look at the BES servers themselves, these are the settings that BES uses to stop having similar issues, we actually went through this sometime ago ourselves and we just copied the throttling policy that BES uses, and most of our issues and disconnects went away

Hi, thank you very much for the quick reply. I will double check the compatibility matrix. In reference to the throttling policy. Should I be applying the SetEVThrottlingPolicy.ps1 followed by the manual settings: Set-ThrottlingPolicy -Identity EnterpriseVault_D0F41A15-9E91-D111-84E6-0000F877D428 -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null
If I do will I be increasing the load on the CAS servers, bearing in mind we also have BES?
