vertica db on two different SAN controllers?

Hi Rahul, I should first warn you that we strongly recommend against using a SAN to store Vertica data. Vertica puts an unusually heavy load on disk IO infrastructure; we have seen both major performance bottlenecks and outright bugs in SAN systems due to the loads that we impose. If you choose to run on a SAN, we don't control the SAN so we can't fix either issue should it occur. We strongly prefer local storage on each node, for both performance and reliability reasons. That said, a three-node database is probably small enough that you can get away with it, if you have a good SAN... You can store data on two different volumes in Vertica, SAN or otherwise; look up "storage locations" in the Vertica documentation for instructions on how to configure this. Adam
