Have you tried an aggregate of the 4 onboard 1gb/s NICs?

I'm somewhat pissed that I'm only able to get about 658Mbps from one
thread on the 10Gbps nic
[quote=cpreston]This is another pro-T2000 report. What makes them special?
The Benchmarks...
8 cores and 4 threads for 32 virtual CPUs and soon up to quad 8 cores and 8

I'll chime in with my additional comments along the lines of the other
responder, who mentioned the large number of cores and threads, etc.
Some of the kernel tunables mentioned have to do with interrupt fanout

Regarding the tape drives and compression
Regarding the tape drives and compression -- this is the part that confuses me.
I can max-out an LTO-3 drive at native write speed at 80MB/s with no
problem using pre-compressed data (compressed Sybase dbdumps), even
with a measly 64kb block size. This is using direct NDMP with 2 Gb/s

Can you share things besides the T2000? For example,

We've been pretty happy with the T2000's.
The tape library is an IBM 3584, the tape drives are IBM's 4Gb FC LTO-3
drives, there's a dedicated 4Gb HBA for each drive, and everything is
connected to 4Gb McData switches

Devon,
What is your data type your backing up? How much data?
Thanks,

RSS is receive-side scaling, which apparently helps improve performance:

I actually just learned about it the other day talking to a 10 GbE NIC vendor.
He asked me that question

Devon, just a few more questions:
So you *are* using jumbo frames? I saw that it was enabled in ndd,
but you haven't mentioned it outright.
Also, what network switching equipment are you using for these tests?
Also, I'm curious, how is it that 4Gb/s LTO-3 drives can write
faster than 2 Gb/s
