12. PA Notes

13. Why? Failure is a fact of life
Complexity breeds failure
Drive failure to be predictable
Complexity introduces multiple recovery scenarios
There can only be one: activation of another database copy
Remove unnecessary redundancy

14. Preferred architecture – namespace design
9/18/2018 8:32 PM
Preferred architecture – namespace design
For a site resilient datacenter pair, a single namespace / protocol is deployed across both datacenters
autodiscover.contoso.com
HTTP: mail.contoso.com
IMAP: imap.contoso.com
SMTP: smtp.contoso.com
For Office Online Server, a namespace is deployed per datacenter
Load balancer configuration
For Exchange VIPs: no session affinity, one VIP/datacenter, per-protocol health checking
For OWAS VIPs: session affinity
Round robin, geo-DNS, or other solutions are used to distribute Exchange traffic equally across both datacenters

15. Load balancing Exchange
Like 2013, Exchange 2016 does not require session affinity at the load balancing layer
For a given protocol session, MBX now maintains a 1:1 relationship with the server hosting the user’s data
Remember to configure health probes to monitor healthcheck.htm, otherwise LB and MA will be out of sync
Check load balancer for “action on service down” or similar setting
Allows LB to reject connections if all pool members are failed, forcing client to utilize another path
Load balancer configuration and health probes will factor into namespace design
Single Namespace / Layer 7 (No Session Affinity) is the preferred approach

17. Exchange connection management
Recommendation is to use one of two types
Round robin
Least connections
Least connections has fast convergence time
Least connections can lead to server instability if “least” server in the pool is inundated with requests
Use “slow start” feature to mitigate this
Round robin has slow convergence time with long-lived connections (RPC/HTTP)
MAPI/HTTP is not affected

18. Geo-distributed namespace

19. OOS namespace planning and load balancing
Always deploy a separate namespace for OOS
For site resilience, follow a bound namespace model for OOS
Even when Exchange leverages an unbound namespace
Namespace manipulation during datacenter activation is not required
Requires persistence at the load balancer
autodiscover.contoso.com
mail.contoso.com
oos-west.contoso.com
oos-east.contoso.com

20. Preferred architecture – DAG design
Each datacenter should be its own Active Directory site
Increase DAG size density before creating new DAGs
DAG configuration
Unbound, symmetrical DAG model spanning across datacenters
No administrative access point
Single network for replication and client traffic
Utilize a third datacenter or Azure for Witness server placement, if possible
Database configuration
Deploy four copies, two copies in each datacenter
Distribute active copies across all servers in the DAG
One copy is a lagged copy (seven days) with automatic play down enabled
Native Data Protection is utilized

Large Mailbox and/or Archive Mailbox

22. Preferred architecture – DAG design
Servers are deployed on commodity hardware
Dual-socket systems only (24 cores total, mid-range processors)
Up to 96GB of memory
All servers handle both client connectivity and mailbox data
JBOD storage
Large capacity 7.2k SAS disks
Battery-backed cache controller (75/25)
Multiple databases/volume
AutoReseed with hot spare
Data volumes are formatted with ReFS
Data volumes are encrypted with BitLocker
