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

Hi

I have 3 media servers running with a 10 GbE NIC (alll running RHEL4). Two of them use a
Intel NIC, and the other uses a NC-510F (NetXen chipset). We use 3 different server models:
a Sun V40Z, a IBM x366 and a HP DL580 g4. On my opinion, Intel(or AMD)+Linux machines
have a so much better cost/performance ratio than anything from SUN (extremely expensive
for the doubtful quality of their service and products).

All of server reach a peak of around 2-2.5 Gbps (250-300 MB/s). Using iperf, we could reach
3 Gbps using NC510F; unfortunately, it seems that the 64-bit version driver is buggy,
and we're obliged to use a 32 bits OS on a machine with 16 GB of RAM (which is very bad), which,
I believe, strongly affects netbackup performance.
I do NOT recommend this NIC at all.

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
