Standby Server - DFS? |
|

Hi there,
Need some advice on if this setup would work and best way to go about
implementing. Am doing centralised server consolidation (30+ sites, 20000+
shares), have been told that clusters can not be justified. So am going with
multiple stand-alone servers attached to a SAN.
For this example I will setup four servers to share the load, even though
for now there is only the one copy of each file, I was planning to setup DFS
so when a DR site was created a replica of the data could be hosted there and
used as a failover.
However for now there is only the Data Centre, so I was thinking if I setup
the shares equally between the four servers, and then created a fifth server,
as a standby, that held every share. In DFS I could add an additional target
link to each item and keep it disabled. In case I had a server failure I
could enable the links pointing to the standby server for the shares that
were hosted on the failed server, until the failed server was restored.
Firstly does this scenario sound reasonable. It appears like it might work
but I think the management overhead in terms of being able to disable/enable
shares when required would be huge. if it met SLAs might just be easier doing
server rebuild!
Has anyone attempted this type of scenario. If im not able to have clusters
or a second copy of the data for DFS to refer to is there any other way to
provide some king of failover in case of a server failure.
Cheers
Anthony. |
