[AusNOG] 10GbE Switching Options

Fri Jul 1 10:44:20 EST 2016

Dear All

Have a look at Mellanox Technologies Ltd… They are doing 100gbit switches for almost the same price as 10gibt !!

http://www.mellanox.com/

With reference to SFP’s cost choose an aftermarket supplier and have them correctly coded… or use https://www.flexoptix.net/en/  most SFP’s all come from the same factory in China.

Kindest Regards

For switching, check out Agema. Their 7648 is literally the same switch as the s4048-ON, just with a different badge on the front, for around half the price. Downside is they have no local distributor, so it all comes from the US, however they're cheap enough that you can keep a few on hand as cold spares.
They have their own switching OS, or you can get whatever whitebox OS that supports it.

Also, if you're after cheap SFP+'s, check out ATOP / Fiber2c. They do 10G LR 10k SFP+'s for around 80 bucks each, and their 1g SFP's are ridiculously cheap. We've been using them for ages, and never had one fail.

I can provide contacts for both if you're interested.

If SFP cost is an issue, are the distances involved too great for 10GBASE-T.

Thanks

Hi Guys!

Thought I’d throw out a few questions and a request for some feedback around some datacenter switching we are looking at. Currently each server has 6 10GbE NICs of which two are dedicated iSCSI that will run through this fabric.

The current requirement is to replace our 1000BaseT switching with 10GbE but the cost of SFP+ modules is an issue and currently twinax has been rules out due do cable management issues (don’t ask :/).
It would be nice to also standardise for our core also so routing is a “nice to have” but not a requirement.

If we could get some decent or support 3rd party SFP+ modules for a good price it would make the Cisco/Brocade options much more attractive but never used the Startech or Netgear SFPs before & I’d like to avoid the vendor finger pointing games.

We are looking at the following

Dell S4048-ON
Pros:
-          Cheap $60 SFP+
-          Cheapest switch cost by 20-30%
-          All in one (no port or IP/routing licences required)
Cons:
-          Different CLI in FTOS, another thing to learn/manage

Brocade VDX 6490
Pros:
-          ISCLI
-          Vendor reputation
Cons
-          SFP+ price $300+
-          Cost of additional port licences  e.g. 24-48 port on demand

Cisco Nexus 3000/9000
Pros:
-          Community support & KB/documentation
-          Vendor reputation
-          Standardise vendor with all other network gear
Cons:
-          SFP+ $1500+
-          IP Lite licence costs

I’d love to hear your thoughts or experience, as I’m sure I’ve missed a few things!

Cheeeeeers,

Alex
