Link Aggregation when using Qnap D4

alexxx

Hi. Please tell me, what option do I choose to combine ports on switch (Zyxel GS1200-8) and on NAS storage (Qnap D4)? I need to improve storage performance.Thanks

GS1200-8 supports Link Aggregation (LAG) static mode of 802.3ad.

Thank you for your prompt response. Which option should be installed on NAS storage for correct operation? Possible option: Broadcast, Balance-rr, Balance-xor.

Balance XOR: This mode balances the network traffic received and sent by your NAS, and requires Static Link Aggregation to be enabled on the switch(es).

I think it is Balance XOR, but you may need to contact QNAP Technical support for the confirmation about which "Port Trunking Mode" need to select on QNAP D4.

QNAP Technical support answered me: Network storage (QNAP D4) uses only 802.3 ad LACP. Link Aggregation (LAG) static mode not supported. Very sorry, I was hoping to merge the ports on the GS1200-8 with my NAS. For these purposes, bought Zyxel.

As far as I know, Zyxel GS1900 series can support LACP.
