Check out my blog entry on this topic:

I just spent some time today with some REALLY smart folks who were using
Intel's 10 GbE NICs with Sun 6900s and Solaris 10.  They can do about
250 MB/s and have the box still function.  They can get it up to 400
MB/s, but when they do that, the box won't respond.  They couldn't run
top, they can't login, they can't run ps, etc -- NOTHING.

So I'm thinking that with Solaris, you're not going to get anywhere near
10,000 Mb/s (1200 MB/s).  Maybe with Linux or Windows and a TOE (TCP
offload engine) NIC, you might have a chance.  (I only say those OSs
because that's where they're making TOE NICs.)  One vendor replied to my
blog post and I'm looking into it.

Hi Group,

Just curious to know if anyone is using 10GB network (fibre/copper, is
copper available yet at 10GB ???) on their media servers or clients and
what
sort of data transfer rates are they getting ???

I'm waiting for my 10GB blade for the switch to come from the US, it's
taking ages !!!!

Also, are you using Solaris or windows on these ???

What's the best you've seen on 100MB and 1GB copper/fibre networks ???

What data rates are you seeing via HBAs 2/4GB ????

Are you using standard backup method or flashbackup ?

I've played around with flash and on a server with about 4.7TB of small
files, I have gone from 10MB/s -> 70MB/s. It's a V490

Thanks in advance,

Dominik
