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.

Re: [Veritas-bu] Multithreaded / Multicore CPUs
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.

Subject: [Veritas-bu] Multithreaded / Multicore CPUs
Hi,
Does anyone have any experience of running NetBackup on Multithreaded /
Multicore CPUs, or knowledge of whether NetBackup can multithread to
take advantage of such hardware? Maybe more important is how the OS
would allocate CPU resources to the tape drives & NICs ... any
ideas/experience would be helpful.
Thinking of upgrading media servers to Sun T2000s, but getting
conflicting opinions of whether it would perform.
Would be NetBackup 5.1, Solaris 10.
thanks, Phil
