While Mirroring is cool you may not have the bandwith to support it to or from a remote site. you should also look at logshipping.

When you say redundancy; how quickly do you need the standby server to be available?
Dear St3veMax,
Well Actually i m working on a live System, where we have SQL Server 2005 running. What i need is to add one more SQL Server 2005 for Redundancy. By Redundancy i mean if My Primary SQL Server Fails, this second SQL Server should take care of all the things automatically.
So either we say it can be done through SQL Redundancy, Log Shipping or Mirroring, That i want to know. Which is the best way to do it, how to do it, what hardware Requirenments are there.
Please help
With Regards
OK;As i see it; You have two options for automatic failover. One depends on your application; if it can use the SQL Native Access Client (SNAC); If so, Database Mirroring would work for you in High Availability mode. It's hardware independant; so you dont require identical servers, disk sub-system, etc.

If the SNAC is not an option; for automatic failover you would be better with an Active/Passive SQL Cluster however this required identical hardware and a shared storage array (HP MSA, EVA, etc).
With the cluster; you have two nodes; one active, one passive. Should the active fail, it will fall over to the passive node and resume processing.

It terms of hardware requirements; what ever works for your existing SQL Server will be good enough for either options; you may require additional hardware for a cluster (such as SCSI/Fibre HBA's, etc)

One final though is that if you need your servers to be geographically apart (i.e. DR/BCP); then Mirroring would be your best bet; but would need to be made to work with teh SNAC and you need to calculate how quickly your application writes to the transaction log; as you would need a WAN link big enough to cope in order to give you the high availability due to the nature in which transactions are committed.
