I was going through the webcast(by David Elfasy) and found interesting about the top 10 myths about Exchange 2010 server. Thought of jotting down the points and share the same which would clear most IT professional myths about Exchange 2010 if any one have. This below points will help you understand highlevel and you can further lookin for the solutions how it actually works with the Exchange consultants/geeks. You can ping me for any queries and let me know if I can be of help in approaching them if any.
You no longer need to back up your Exchange Servers.
Yea there are HA feature available were you can avoid taking backups but there are also some good reasons why you want to take backup like for simple reason the company complaince wants you to have data available for a long time(defined period).
If you want to have Antispam Transport rules and Internet connectivity, you need Edge Transport Servers
Thats not true, you can have almost 95% of functionality of Edge server role on HUB server . Edge transport server is an optional it gives you added feature functionality and also gives you a separation between your existing organization getting deployed in the perimeter network
Client Access Server must be Place in you DMZ
CAS is a server that all clients connect to, most of the email clients like mobile access, pop3, IMAP, rpc/http, webmail was used from internet to connect FES, if you are familiar of earlier exchange you might have heard about Frond End Server in the perimeter network. Exchange 2010 doesn’t have to be reside in the perimeter network actually it cannot reside in the perimeter network
Microsoft does not recommend or support Storage Area Network(SANs) for Exchange Server 2010
Well there’s a brand new improvement in Exchange 2010 Store which gives you better performance of IOPS and scalibility. You could use Inexpensive disk for no. of reasons. That it doesn’t means Microsoft doesn’t support SAN ISCSI/FIBRE storage, abosultely not. Its still welcome to use and its no longer need as mandatory requirement for kind of clustering.
To support clustering, you need to install Exchange Server 2010 Enterprise Edition
Not true, You can still use standard edition for your DAG but Operating system needs to be as Enterprise edition as pre-requsite.
You do not get any of the benefits of Exchange Server 2010 unless you upgrade to Outlook 2010
Not really many of the benefits are available using outlook 2007 but yes there are new fucntionality added which are only possible using outlook 2010 that would not available in old version.
You cannot implement a High Availability solution unless you invest in Hardware Load Balancers
HLB sitting in front of the CAS servers to respond email clients do I really required one, not really but in most case I would want them but ask me you really don’t require them.
You want High Availablilty in Exchange? well you need at least four servers!!!
Not really, it was true and a limitation you required to have in Exchange 2007 but not in Exchange 2010. Earlier version cluster MBX server couldn’t co-exist with the server roles like HUB/CAS.
Single instance storage is gone.Ok well this one actually is true but its not all that bad.
This is actually true. The reason for SIS was gone completely is that Microsoft has revamped the database storage engine in such a way that resulted in tremendous performance which reduced IOPS demand almost 90% for Exchange 2003.
Transitioning from Exchange Server 2003 is even more painful than it was to migrate from Exchange 5.5.
It is quite simple to migrate, it is lot more straight forward to migrate to Exchange 2010 than exchange 5.5.
