BackUp device for local or colo storage

If you identify a single server that needs more speed, you can go up to triple or quadruple GigE if need be before making a leap to 10GigE connections.
What's the current cost for a 10 GigE card. Assuming he doesn't already have open ports of GigE, he'll need to buy regardless.
-
I'm surprised, an unmanged 10 GigE swith 8 port is $760

A two port card from Dell is $650. Third party might be considerably less.
-
Yup, I've been pushing Netgear 10GigE for a long time now. I think that Dell has some decent 10GigE fiber switches for around $2K as well.
-
Damn the 12 port vs the 8 port is double the price of the 8 port, $1450.. ouch!

I bet if you check the backplane gets a lot faster.
-
It might be the route we go with, 10GigE switch with bonded NICS or dedicated 10GigE NICS on each host.
-
How many VM hosts do you have?
-
1 Currently that is stand alone.
The equipment we're looking into would be a dual host setup. "Primary Primary" so to speak.

A long time ago I remember seeing some documentation (sales pamphlet) for industrial 10G switches. Small little units, 5 ports.
I can remember for the life of me their name though as this was years ago.

Netgear has some fairly inexpensive managed switches that have 10G uplink ports. I think in the 800-900$ range. You could look into those if you don't need a ton of 10Gbe ports.
-
Yeah I'm thinking we won't need many.
Just device to device basically.
From XenServer host to onsite backup device.

Yep, I can't remember the model number but Netgear, in the last year, released a model with 4 10Gbe ports.
-
Likely four ports won't be enough.
-
@scottalanmiller Even if we spent for the 10G NICs in the servers?
2 Hypervisors 1 Backup device.

Oh, so two servers and one backup device and one uplink to the rest of the network? Four ports might do it then. But.... no redundancy at all?

Cost consciousness.
Is there that much added value in doubling what we have for those "if" events.
-
Nevermind, I was thinking about the S3300 series, they have 2 uplink ports. There are 2 10Gb copper or fiber ports that you can use interchangeably... but only two at a time. They do have the XT712T but I have a feeling that may be a bit too expensive.

NICs and switches tend to die and it doubles throughput.
-
Well even in that case I would still look at a bigger switch with 8 - 12 ports. possibly with some level of management on it.
-
Can you do port bonding? I thought I read someone suggest that but didn't see your response. That would be a really good stop gap solution for now.
