We can configure 10 databases for 32-bit operating system.On a 32-bit system, database mirroring can support a maximum of about 10 databases per server instance because of the numbers of worker threads that are consumed by each database mirroring session.
For 64-Bit Operating system we can mirror more than 10 databases depending on the number of processors and worker threads. Many company has deployed more that 10 Databases as mirrored.
