Re: [Veritas-bu] Multithreaded / Multicore CPUs
I have built and used SUN V490s as media servers in the past and they worked fine. They have dual core CPUs. It was running 8 x LTO3 drives without an issue. The server had 4 x dual core CPUs which is 8 virtual. I hear / seen a lot of good things about the T2000s as web/app servers but have not heard of anyone use one as a media server. Would love to hear about people's experiences with them as media servers. The tests I've performed on them as web/app servers show that they scream. Not to sure I'd use them as a media server. It's the whole single CPU / 8 core thing (CPUs can die, unlikely but if it does the servers dead), not as many slots for scsi cards etc and less RAM. I'd prefer a V490 or V890. Ideally I'd love to try a SUN X4600 server but they are not supported yet. I'm told they're on the way but not quite there. Peter Morales might have more insight here. > Maybe more important is how the OS would allocate CPU resources to the tape drives & NICs Solaris handles this fine, you could always see the virtual CPUs being allocated and gobbling up the load. From what I've seen it's the Windows servers that have a lot of trouble.
