Looking to have a failover exchange server and was looking for suggestions on my options.

Post by John » Sun, 03 Sep 2006 02:25:42


Besides a backup MX I would like to have a failover Exchange server in place
for maximum uptime. My Exchange 2003 is at a Co Lo and would prefer a
service versus buying more equipment.

Does anyone have any experience with this?


TIA

i,

Thank you for posting here.


I would like to confirm your question as: You would like to implement an
Exchange environment which includes two Exchange Servers Server1 & Server2

- Server 2 contains the exact copy of Server1

- If Server1 fails, Server 2 can then be used instead of Server 1

As far as I know, there's nothing inherent in Exchange to accomplish this.,
we cannot accomplish this goal unless an Exchange Cluster can be
implemented in your environment. For your information, a Cluster is two or
more Exchange Computers (Nodes) connected by special devices, but appears
as a single virtual server in the network environment. I would like to
provide the following resources for your reference:

Meanwhile, according to my experience, I would like to provide the
following articles for your reference. A recovery Servers is used but the
goal is different in this article. Hope it is helpful:

Also using a 3rd party implementation like SRDF one can do this with a high
degree of reliability, but the associated cost is not insignificant. Using
3rd party products which provide byte level replication, such as Double
Take, one can reduce the associated costs, but the level of reliability
decreases as these products are not Exchange aware and the databases may
not be in a consistent state.
With either scenario, client failover is unlikely to be seamless due toc
lient name resolution issues. Typically this can be accelerated to
somedegree by writing scripts to update DNS, WINS and/or purge the client
local DNS cache.

These types of solutions protect against a limited set of disaster
scenarios. Viruses, database or AD corruption, are a couple of common
scenarios where replication may not be effective. I do have several
customers who are implementing the solutions I described above in various
configurations. My company recently put out a study of email related
failures which might be helpful in framing a discussion with your clients
about what kinds of disasters they are trying to protect against. It's

If anything is unclear, or if you need further assistance on this issue,
please let me know.

Have a nice day!

A service solution would be MessageOne. A software solution would be
LifeKeeper for Exchange (the company I work for). There are other
solutions on the market as well, just Google around for Exchange DR and
you will find people like Neverfail and DoubleTake.
