Hello Folks, This is my first post. Whats the difference between Open Cluster Stack & ROCK. I guess both of them are Clustering Products. Are they different or are they chips of the same block? For all those who don't know OCS, here is the info: http://www.hpcwire.com/hpc/930547.html http://www.linuxhpc.org/stories.php?story=06/11/13/8040251 Go through them carefully, they all contain a word or two about ROCK. -- Kind Regards, PARAG .
