If you use iSCSI, you can have a two node cluster setup to reference an
external array (external array contains your drives). If you want more
than two nodes, you will have to look at fiber attached storage or
NAS/SAN devices. Definitely use Active/Passive for Exchange in a
cluster environment.
Couple of things -
Is this cluster for mailbox servers or for Front End servers? If for
front end servers and you have Windows 2003 as the OS, you may want to
look into NLB (Network Load Balancing - high availability). Other
things come into play based on your setup (such as mail filtering and
maintaining identical filter Databases with your filtering software).
Look at these options closely when designing your solution....
Also, do a quick search on MSExchange.org as there are detailed
tutorials for 2 node clustering of servers for Exchange Mailbox servers.
For front end servers running OWA and RPC over HTTPS, I would recommend
Network Load Balancing.
Contact me off list if you need any additional information after
researching....
Chris

All,
I am looking into clustering for exchange using active / passive setup.
Have looked at both Google and Microsoft and have found an abundance of
information to read and I don't think much is relevant to what I am
trying to find out. Can anybody point me to a good reference site or
book? Or can anybody tell the answers to the following question
1. does clustering have to be setup on SCSI? Or can
you use IDE?
2. do the machines has to be identical in hardware
setup (this I believe is true but am unable to find this in black and
white)
many thanks for your help
Simon
