We are planning to put DNS and DHCP services onto a NW6.5 (sp4) cluster and
would value expertise on hardware.

Initial thoughts are a 2-node cluster of HP Proliant DL360 boxes (1U, RAID1
mirrored discs in each box), or is 3-node significantly more resilient? We
will need a small amount of shared storage for DNS as I read the docs -
what is simple and works well?

Our file, print & Groupwise servers are in a SAN (not clustered yet) and
I'd like to be able to set up a cluster for DNS/DHCP separate from the SAN
at present.

I appreciate all comments.
