1. Is SQL server handle 15 petabytes of Database size ?
If possible then please help me how to design the database in SQL Server ( including Clustering , Load balancing etc..)
I don't see any problem in stating that as the database size is limited by storage, in this case I strongly suggest to involve Microsoft CAT team for more help.
For what it's worth,
SQL Server 2005 has a database size limit of 524,258 TB
SQL Server 2008 has a database size limit of 524,272 TB
I hope this helps!
1 petabyte (PB) = 1000 terabytes(TB)
so sql server 2005 db size limit = 524 PB
what is expected time for full backup ?
