BackUp device for local or colo storage

@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.
-
@coliver Possibly.
The biggest bottleneck with the existing backup solution is the server performing the work. Which is just constantly getting hit.
Port bonding on the new setup would reduce some cost, at the price of reducing what we can run VM wise since those ports would be tied up.

The cost of an additional 4 port 1Gbe card is minimal. You could easily add that to all your systems for a fraction the cost of the 10Gbe switch and adapters.

I'm forking to a new thread. Will post a link shortly.

Wouldn't you carry off daily?
Sorry just saw this, its a nuisance to have to swap tape or drive daily to do it. Our current plan is carry off weekly.

Remember this post when you ask for a full second server to run your VM environment.

What do you mean? you typically bond all the NICs in a VM host together and all the VMs on the host share the pipe.
Next question, do you really use 800 Mb (realistic use from 1 Gb ports) on each server at the same time?
-
I've never bonded all of the NICs as we haven't had the need for it.
In most cases we've simply allocated a specific NIC for a specific number of VM's.
-
Unless you need to leave bandwidth overhead for something, why split it?
It's just like you always you OBR10 unless you have a specific reason not to.
-
Why Bond when I'm still only capable of pushing 1Gb/s at best?

Aren't we seeing bottlenecks, though? Bonding is a standard, best practice.

What is limiting you to 1Gb/s if not the GigE link?
-
And you bond for failover, not just speed.

Up to four NICs.
