 Support for OCS, Platform's Open Cluster Manager - Dell Edition for 3 years is $10,434.  I think we can do without, we could always fall back to CentOS/Lava.  Plus we can peruse their knowledhge base which is rather good.  LSF licenses are perpetual so we're good there. Support for OCS, Platform's Open Cluster Manager - Dell Edition for 3 years is $10,434.  I think we can do without, we could always fall back to CentOS/Lava.  Plus we can peruse their knowledhge base which is rather good.  LSF licenses are perpetual so we're good there.

A 12 port Infiniband switch is probably $3,200 and a 48 port gigE switch about $1,750.

 Or downsize the cluster when things go awray, anticipating the new cluster.  Petaltail and Swallowtail could take over each other's services but it would take time, and be disruptive if it is Petaltail. Rebuilding Petaltail would imply wiping Swallowtail, and afterwards, reinstalling/relicensing commercial software. Or downsize the cluster when things go awray, anticipating the new cluster.  Petaltail and Swallowtail could take over each other's services but it would take time, and be disruptive if it is Petaltail.
