Cluster 2.2 - Terminal Concentrator
2007-12-24 22:12:00
I want to build a two-node cluster testbed with SC2.2.
I have 2 servers suitable for clustering - each has
sufficient LAN/SCSI adaptors; I also have a couple of
D1000 enclosures. To reflect the production rig, I
would wish to use SDS as the volume manager.
Given this specific configuration (2 nodes, SDS), do
I absolutely, positively _have_ to have a terminal
concentrator? The install guide goes to some
length to describe the role played by the LTC
in failure fencing and as a nodelock device, but
none of these scenarios apply to a 2 node cluster
with SDS.
Bottom line is, I don't actually have a spare LTC
device.
Question is, can I set up a test cluster, in the
manner described, without one?
Thanks for your consideration.
