Re: [Treebase-devel] Disk space for treebase production database

[Jon A. <jon...@ne...>]

I would like to move the database to the SAN if the performance is acceptable to Bill. This move will give us:

1) much needed space and room to grow
2) redundancy. Currently the database is one local disk of one of the physical servers. I can not move the database to another server if the host goes down.

Bill, if this is OK, please let me know which night in the next week or so that U can move the database. It will probably take about 12-16 hours. My plan is to put a down for maintenance message on the website. We don't want anyone submitting while we are doing a restore. Alternatively, if you have a way of disabling submissions, we do not need to disable the website.

thanks,
Jon
