This allows the management node to delegate all management responsibilities for a set of compute or storage nodes to a service node so that the management node doesn't get overloaded. Although xCAT automates a lot of the aspects of deploying and configuring the services, it still adds complexity to your cluster. So the question is: at what size cluster do you need to start using service nodes?? The exact answer depends on a lot of factors (mgmt node size, network speed, node type, OS, frequency of node deployment, etc.), but here are some general guidelines for how many nodes a single mgmt node (or single service node) can handle: - Linux: +* **[Linux]:** Stateful or Stateless: 500 nodes Statelite: 250 nodes - AIX: +* **[AIX]:** 150 nodes These numbers can be higher (approximately double) if you are willing to "stage" the more intensive operations, like node deployment. @@ -58,6 +58,6 @@ When you have NFS-based diskless (statelite) nodes, there is sometimes the motiv If you still have reasons to pursue HA service nodes: -* For AIX, see [TODO XCAT_HASN_with_GPFS] -* For linux, a couple prototype clusters have been set up in which the NFS service on the SNs is provided by GPFS CNFS (Clustered NFS).
