Fuld HA i Exchange 2010 med 2 servere
Modsat Exchange 2007 som kræver minimum 4 Exchange 2007 servere (2 med CAS/HT rollerne og 2 noder til en CCR-baseret Mailboks server) for at levere fuld HA (eliminere alle former for single point of failures) i en Exchange 2007 baseret løsning vil Exchange 2010 kunne levere fuld HA med bare 2 Exchange 2010 servere. Grunden hertil er at DAG (Database Availbility Groups) som er efterfølgeren til CCR/SCR kan sameksistere med andre Exchange 2010 roller på samme fysiske servere.
Dog er der en lille "aber bei" og det er at det ikke er supporteret at konfigurere både Windows NLB og Windows Failover Clustering på den samme server (læs mere om hvorfor i KB arktikel 235305). Det betyder du skal ud og investere i 2 hardware-baseret load balancere for at opnå HA for indgående trafik fra ikke-Exchange baseret transport servere samt klient traffik (OWA, EAS, IMAP, POP og Outlook Anywhere).
Hav også in mente du skal benytte Windows Server 2008 Enterprise edition til disse 2 Exchange 2010 servere.

Deploying Exchange 2007 Multi-site CCR Clusters – Do’s and Don’ts (part 1)
Back in 2006, from when Exchange 2007 RTM’d up until Exchange 2007 SP1 RTW’d, the Exchange Product group not only considered Cluster Continuous Replication (CCR) to be a local datacenter high availability solution but also a viable site resilience solution. Actually, CCR was the only native functionality that could be used to provide site resilience. Of course there were/are alternatives. You could/can use Single Copy Clusters (SCCs) combined with a software-based third party replication solution or have the storage vendor replicate data on the storage layer (typically block level). Several vendors also make it possible to combine CCR with storage layer replication, but why not take advantage of native functionality rather than investing in an expensive 3rd party solution?
