Then choose "LSST for SDSC". This is a powerpoint presentation about = the project that contains some information on the computing = requirements.

Problems with Oracle: What is the maximum number of partitions for a = database? Will hierarchical file management systems does it work with? = What if that system needs to be extende?. Is Oracle's one-cluster hence = one-architecture technology right for the project? Does Oracle RAC tie = you to a single vendor? Can RAC's communicate with other RAC's? Does = anyone think this will be done using RAID10.

I'm not sure how much of the data will be online annd how much will be = nearline storage. =20

This quote appears in the following article:=20 http://www.computerworld.com/hardwaretopics/storage/story/0,10801,95694,0= 0.html?nas=3DDM-95694
" When it's in operation in 2011 at a site still to be determined, the = telescope being built for the LSST project will collect data at a rate = of about 6GB (equivalent to one DVD) per 10 seconds, generating many = petabytes of data over time. One petabyte equals roughly 100 times the = printed contents of the Library of Congress. The LSST project "pushes = forward database technology dramatically," says Philip Pinto, a physics = professor at Steward Observatory at the University of Arizona and a = member of the LSST project's board of directors. "The LSST database will = probably be the largest known nonproprietary database in the world."=20 So if you were faced with the task of storing 50 Terabytes per day, what = kind of architecture would it require?
Do you think Oracle would hold up with a transaction rate of 600 = Megabytes per second?
The architecture of such a beast could drive out some interesting = developments for more general use.
