Active/Active clustering

Hi all -
i am fairly new to clustering and here is what i am trying to accomplish:
- 2 DL380 g4 with 5 drives each.
- 2x Raid 1 for sys files
- 2x Raid 1
- 1x Raid 0
I dont have an external SAN device for shared external disk and my question
is A)do I need external SAN device to cluster two servers?
B) Can I use the last drive (Raid 0) for quorum drive?
C) when I run the "cluster wizard" on node 2 I can add the node to the
existing cluster but I am unable to add any disk resources?
thanks for the help!!

Hi
For clustering, you need shared storage. This is in the form of a SAN.
No SAN, no cluster.

|||Thanks for you response! So, I need an SAN attached storage device, so the 2
servers that i will be clustering can only have 2 drives each for sys files?
and everything else should be on the SAN? am I correct?
thx

The OS and the SQL Server executables gets installed on the local drive.
Data and Quorum go on the SAN.

Hi,
To get clustering to work correctly you need to have a disk set that
can be accessed from both nodes so a SAN or external disk array of
some form is needed. This is why you can add the second node but not
see any disk resources to add.
With regard using a RAID 0 for the quorum, I would say no as if the
quorum goes the cluster goes - again this needs to be on a disk set
that is accessible to both nodes.
Hope that helps,
Digger
