ReadyNAS NIC bonding compatible with Cisco SG200 Switch?

I setup 802.3ad LACP bonding on my Neatgear ReadyNAS box. The bottleneck is now my router since I only have 1Gig ports on the back and can't setup bonding on my router.

If I get this Cisco Switch (it says it supports 802.3ad LACP) will I then be able to experience the full speed of "2 Gigabit" port speed?

Here's the switch: http://www.newegg.com/Product/Product.a ... -_-Product

I'm trying to transfer files faster than the 90MB/sec I seem to cap out at. Sometimes it goes faster, but not always.

    What system are you trying to transfer the files to? Does that system also support LACP?

    I don't know about the SG200 (I have a GS724Tv3 from Netgear).

    LACP can increase speeds if you have multiple data flows (for instance multiple users). But each data flow is still limited to 1 gbit.

    My Netgear ReadyNAS is setup as 802.3ad LACP. I want to plug the 2 ethernet cables into this Cisco switch and setup a 802.3ad LACP for those 2 ports.

    I have NIC Teaming already setup on my desktop computer and I want to plug those 2 ethernet cables into the Cisco switch and setup a 802.3ad LACP for those 2 ports.

    With everything connected and setup as 802.3ad LACP (NIC bonding) I want to accomplish closer to 2Gigabit speeds vs. 1Gig.

    And LACP is not designed to do that, unless you have multiple file transfers happening at the same time (and perhaps not even then). See page 7 here: http://www.ieee802.org/3/hssg/public/ap ... 1_0407.pdf

    Maybe try MLB first, since that doesn't require you to buy a switch. And its possible that MLB will increase your speed.

    If you do buy the switch, use the "layer 3+4" xmit hash in the NAS (and the switch if it has it).
