over another (SAN vs DAS) particularly when the quality and reliability of the solutions are dependent on the architecture, components and people. And I think this thread is a classic case of assuming a SAN mandates superior quality of service; which we know is not the case. Regards Peter Marelas

You can monitor the bytes written column with bpdbjobs. If the job is active and the value does not change something is probably wrong. Except for control jobs (e.g. Oracle RMAN). Regards Peter Marelas -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf

Re: [Veritas-bu] 10GB network + perf questions etc

If it's the card I'm thinking about the TCP checksum is already offload to hardware. In fact most gigaswift cards support this today with 1 Gbit technology. I think a great deal of tuning would be required to achieve anywhere near 10 GB w/ a single TCP stream. Regards Peter Marelas

Re: [Veritas-bu] Multithreaded / Multicore CPUs

2006-11-23 Thread Peter Marelas
NBU forks multiple processes per job so you should benefit from multi-core CPU's. However, since backup/restore depends greatly on data input (network) and output (tape/disk) you should ensure everything in the data path (drivers, etc) can utilise multiple processes. Regards Peter Marelas
