Hello,
My question is, do you see a need for 10G card on Master or SN Legato
servers ? considering design recommendations ( 50 client per server or SN
as a start)and client load with Master server or SNodes 1 or 2 GB ethernet
seems to do the trick, what might be the reasoning behind 10G on any
platform ? Should you not look to use SN licence and or off-loading
ethernet traffic and utilizing block level backups ? i tend to connect
any servers who's backups run longer then 4-5 hrs and or over 100+ GB (
with no room for any improvements) with SN licences, i wonder how the rest
of the admins use this guidelines ?
For those who have made such an move, can you explain what were the
driving factors, performance limitations and how has it improved since you
used such
technology's, that would set a guideline for the rest of us ?
Similarly, i don't see a huge need for 8-10 G FC except for very large
shops doing specific implementations ( Multi TB backups, multiple high
performance Drive i.e LTO4's),

Re: [Networker] [Summary so far] Re: best platform for newest networker?
We have one environment that has an HP-UX Storage Node (solaris
master), using a single 10GbE card for backup network, and 2x 1GbE for
admin/meta-data/clients not on the proper backup network. Overall, I
don't have a problem with the HP...it performs well and does what it's
supposed to do. But I've also never pushed it's limits the way I have
with my all-solaris shops, where I've found my bottleneck appears to be
solaris i/o handling (note: v490/Solaris8). No matter what I do with that
older solaris setup, I can't seem to break the 180MB/sec aggregate
max...even with 4x 1GbE (TCP/IP Offload cards) and 6x STK 9940B (30/60/90M
spec).
I also have to agree with Curtis' comments regarding pro-Solaris
folk (unix is unix....and it is definitely NOT windows, yech). I'm
pro-Solaris myself, and looking forward to using the T5220 w/8x core,
solaris 10, and (if I'm lucky) 2x 10GbE for my new master/SN
infrastructure. However, I still plan on designing it to only push 6
tapes drives (IBM 3592E05), whether I get 2x10GbE or 8x1GbE for my backup
network connections.

I think the pro-Solaris folks would be just as OK with HP-UX or AIX if
you know that platform better. Personally, I prefer Solaris because of
an iostat that understands tape drives and because of snoop. If you
prefer HP-UX, I don't see any issues with using it as your NetWorker
server. It doesn't have the downsides that people listed of Linux or
Windows.
My one question would be to find out how well it can perform. I'm
hearing really good things about Sun boxes, its recent IP stack, and 10
GbE cards. Being able to send 500 MB/s into a backup server is a
powerful thing.
I think AIX comes with TSM pre-installed. ;)
