[Zope] Need for advice ...

By desire of the gods and the ebays lords a bargain Sun Enterprise 250 arrived to my hands this week. The machine is equiped with 6x50GBytes SCSI HDs that can be setup in RAID 0, 1, 5 and 01 combinations and two Sparc 64bits CPUs with Solaris 10. The idea is to use it mainly for Zope/ZEO/Plone hostings. Anyone has experience or knows of sources of documentation for tunning a simmilar system to take the most of Zope (ZODB tricks, ZEO setup,...)? Thanks in advance for any help!
