As Martin notes, we met with RE about the near future of several servers.
Long-and-short:
a) The new machine, aka Peach, will replace Pear and Grape as soon as it's configured. RE is setting it up with a single Tomcat install, but we're going to try running multiple instances of it instead of having an installed codebase for each instance like we've had in the past. Once we're ready to test it, we'll get Grape's webapps and Pear's webapps on to it and test it for a week or so. When we're happy that things are working we'll bring down Grape and Pear.
b) when Grape comes down, it will be rebuilt as an additional node in our webcluster - this should happen by Christmas.
c) when Pear comes down it will become a BCP (bulk-copy) machine for Peach and Mango (the DB server), providing us with a rapid-recovery scheme. This build should be done by the end of February.
d) Once the CFI machine is purchased it will be replacing arugula as the NFS/disk box, and arugula will be added to the cluster. Timeline ASAP.
e) Lettuce will wait until we have a chance to put time in to the MoEML map refresh. We expect to begin in the new year. When Lettuce is no longer required for MoEML we'll add it to the cluster.
f) RE will look in to Cress and let us know what he thinks we should do with it.
