LACP @ 6Gb speed?

post #1 of 16
Thread Starter 
So, I've currently got my three computers connected via a TP-Link SG2008. It's a great switch, especially for the price I paid, but at this point I was thinking of upgrading to add addition gigabit connections between all systems. Now, I know that it technically won't give me 6Gbps if I have 6 gigabit Ethernet cables going from all devices, but how much could I feasibly get assuming that I am not bottlenecked by drive speed? This is just a lower cost alternative to going to 10Gb, which is just not "consumer" ready yet. I would definitely prefer it, but 3 NICs + a switch would take a pretty penny that I don't want/have to spend.

I understand the true design of LACP was to increase throughput for multiple devices, which is the main reason I am upgrading. (Multiple Plex streams, plus back ups from my two main desktops to the NAS (third computer), and all of my media is located on the NAS.) However, I would like to see increased speeds as well since I will be adding a 8TB Raid 0 array to it as well. Which feasibly could put me at over 300MBps, but I was just wondering if that's something that is something that is feasibly attainable via 4Gb/6GB interconnection.

If I need to explain further what I'm trying to do, please let me know.

If you need LACP trunks with point-to-point connections with speed above 1Gbit - you must use management switch which support Level 4 load balancing (TCP IP/port hashing). I use LACP trunks 4x1Gbit and can get up to 3.9 Gbit/sec during iperf tests and near 300MB/sec copy speed (disks can't write data faster).

Thanks for the info. Where would I find that information and which switch to get? I was planning on the one below. My plan was to get 3, 3TB Seagate NAS drives and run them in Raid 0 for my gaming/editing needs.

I prefer HP Procurve managed switches. All required info you can find on hp.com (technical details). Models with level 4 load balancing: 2810, 2530, 2900, 3400cl, 3500yl, 2910al and many other.
Also, I can't found any info about level 4 functionality on tp-link site from url you posted. Anyway can't say something positive or negative because haven't any experience with them.

I 'll shoot them an email and see what they say. I have a 5 port unmanaged, my current 8 port "smart" managed switch from them, and they have worked well while being cheap and power efficient, so I'd prefer to stick with them at the price that it is currently listed at on amazon (130$)

EDIT: and 2 +rep to you sir for the help!

Procurves kick butt. I love those switches. smile.gif

I decided to go a different route. Not as much speed, but definitely a lot easier to get up and running. Bought a 4Gb fiber switch including all 16 transceivers, and dual 4Gb fiber NICs. Should get it later this week! Everything (including all interconnects for all three systems) cost just as much as the switch I was going to buy which doesn't even support the Level 4 load balancing that I would have needed. So, I"m pretty happy.

4 Gb like Fiber Channel? You might be surprised when you try to integrate it..
