16 nodes here (CentOS 5.2). No problems relating to cluster size. Invest in your network--you won't regret it. We've repeatedly found RHCS is only as good as the network connecting it. We currently have Juniper EX-series switches connected to multiple interfaces on each node. The physical interfaces are bonded in active-passive mode. We're considering active-active (LACP). What have others done? -Jeff ________________________________ From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Alain.Moulle Sent: Friday, March 13, 2009 6:21 AM To: linux-cluster@xxxxxxxxxx Subject: CS5 : limit for number of nodes in cluster Hi , it seems that the CS5 supports up to 128 nodes ... (whereas it was 8 with CS3 and CS4 ? ) did some of you have tested at least the CS5 with more than 10 nodes ? does it reveal any big problem or restriction to have big clusters with CS5 ?
