Do You Need a 10GbE Router for 10Gbps LAN Speed?

10gbaseethernetrouterswitch

We're planning on creating a 10GbE network for our office. I've got a list of hardware that all support 10GbE, only the router isn't 10GbE:

  • Synology DS3612+ – 12 Drive NAS
  • Intel X540-T1 – 10GbE Network adaptor for NAS
  • Netgear XS708E – 10GbE Switch
  • SANLink2 – Thunderbolt – 10GbE adapter
  • Cat7 Cables

Setup is as folows:

  • Our gigabit-router (NOT 10GbE) will be connected to the Switch
  • Computers will be connected to the Switch via SANLink2
  • The NAS will be connected to the Switch via 10GbE adaptor

What I'd like to know:

  • Will the computers be able to connect to the NAS at 10GbE?
  • Will the router slow things (other than internet) down?
  • Any other drawbacks?

EDIT:

The needs for this network are the following:

  • We want to do 4K video-editing directly from the NAS.
  • We want to transfer 2TB of data to the NAS in less than an hour.

Best Answer

Will the computers be able to connect to the NAS at 10GbE?

Yes, if both the computers and the NAS are connected to the switch at 10GbE and do not require routing (ie. both are in the same subnet and VLAN).

Will the router slow things (other than internet) down?

It will slow anything which passes through it down to gigabit, but only if is faster to begin with.

Any other drawbacks?

This could be the perfect setup for you, but it could also fail to deliver under certain conditions. Since we don't know what it has to deliver, it's hard to tell. It all depends on how you will use it and what you expect from it...
