OK so someone will. We're still investigating why the OakTable cluster fell over, but it's neither a Linux thing (can support up to 32 nodes) or an inherent RAC thing. As a matter of fact, I think it's a damn good proof point of both the technology and James Morle's technical nous that it even got that far. Remember what they did was to boot 10 random laptops off a Linux CD and cluster them to a NetApp storage device. The laptops were whatever OracleWorld Copenhagen attendees had with them, so they were from a variety of hardware vendors. From memory, it was RedHat 7.2 and 9.2 of the database. Getting it to even work it just amazing! Funniest thing about it was the photo I got sent showing all these laptops open, but on their sides, in the cluster!

HTH. Additions and corrections welcome.
