#Exchange2010
Interesting, from WES 2010 session ‘WA25: Best Practices in Deploying Microsoft® Exchange for BlackBerry’ jointly presented by RIM and Microsoft Jeff Mealiffe (Sr. Development Lead, Scalability & Capacity Planning) it says:
- Database IOPS per user is equivalent to a Microsoft® Outlook® client, not 5x and not 3x
- Our past data represented the worst case scenario
-
- Workload assumes both BlackBerry and Microsoft Outlook clients active
- 100% BlackBerry enabled users
- High density of BlackBerry users on a single storage group
- Our focus in the past has also been on providing a single impact number
-
- Database I/O more expensive and needs to be our focus (random I/O)
- ransaction log I/O gets optimized well by disk infrastructure (increase is not as relevant – sequential I/O)
- Dual clients per user active (Outlook and BlackBerry )
-
- DB IOPS increase by 1.85x for BlackBerry enabled users only
- DB IOPS increase by 1.7x for BlackBerry enabled users only (5.0.2
optimizations) - DB IOPS with optimization equivalent to an outlook client
- Truly mobile users (only BlackBerry client)
-
- DB IOPS equivalent to an Outlook client
BES 5.0 SP2 DB IOPS increase by only 1.7x with Exchange 2010 compared with 2.16x on Exchange 2007 with BES 5.01
Mail server role
- Mail server CPU recommendation is about 1.4 -1.5x MCycles/mailbox recommended by Microsoft
- Memory, same as what is recommended by MS for outlook users/clients
CAS Server role
- CPU core recommendation is inline with 4:3 ratio recommend by Microsoft for CAS:Mail server
- NSPI connection count needs to be increased to 1 per BlackBerry smart phone – default is 50 (too low)
- Throttling needs to be disabled for the service account used for the BlackBerry Enterprise Server
