Hello. I have 4 network interfaces of 1 Gbps. How can I configured 2 interfaces into 1 with a speed of 2 Gbps?

Or all 4 interfece 1 Gbps into 1 - 4 Gbps?

 This interfaces only for connect NAS??

And I also have 10 Gb ports connected to the servers, but as I see it, 1 of the 2 ports is active and the second one is not. Is this correct or are they not configured?

Hi,

You can't.

Or all 4 interfece 1 Gbps into 1 - 4 Gbps?

This also can't be done. Ethernet ports can't be combined to get a faster port.

What can be done is to create a trunk with LACP, but that requires a properly configured level 2 or level 3 switch and you still won't get speeds faster than 1Gbe (or 10Gbe for a trunk of 10Gbe ports), but you will get bandwidth management so users connecting get the best speed possible.

This interfaces only for connect NAS??

Can't tell the portal configuration from the screenshots, but I recall that you can use portals for NAS or iSCSI.

And I also have 10 Gb ports connected to the servers, but as I see it, 1 of the 2 ports is active and the second one is not. Is this correct or are they not configured?

Ports which show a Down status have no ethernet cables plugged into them. Ports that show Active have a portal on them. Ethernet ports not connected to the network can't be used.

Hi.

Thanks for the reply.

I have one more question.

A server is connected to this storage via the intel X550-AT interface (2 10 gb ports). A virtual machine with a database slows down a lot. As it turned out, when accessing the storage disks via iscsi, the virtual machine transmits data via 2 ports of the controller X550-AT simultaneously (see screenshot) Are there any settings in the storage of 10 Gb interfaces with which to transmit data only on one interface and in case of a failure on the second one. Or are these server-side settings?

Thank you.

Hi,

Your configuration is odd, you have created multiple trunks but have only one port used, which rather negates the advantages of a trunk.

As the ports are trunked, the policy is set by the trunk mode. There is no failover trunk mode in the Vess R2600.

Are there any settings in the storage of 10 Gb interfaces with which to transmit data only on one interface and in case of a failure on the second one.

I don't know the OS on your server, but if it's Windows Server 20?? then I would suggest deleting the trunks (you have to delete the portals first), then create new portals on the ethernet ports you have connected with the same IP and using Windows multipathing instead.

Windows multipathing has a failover only mode that will do what you want.

  • Fail Over Only - Policy that does not perform load balancing. This policy uses a single active path, and the rest of the paths are standby paths. The active path is used for sending all I/O. If the active path fails, then one of the standby paths is used. When the path that failed is reactivated or reconnected, the standby path that was activated returns to standby.

Multipathing is only available on Windows Server products.

There are plenty of tutorials for setting up Windows MPIO online.

Hello. The trunk is configured for NAS, and 2 ports of 10Gbit connected to OS WinServer2016 server. The server has MPIO configured with RoundRobin. Do I understand correctly that all MPIO settings are made on the server side, but not on the storage system?

This sertting for only 4 porta on 1 Gbit/s? And there is no such setting for 2 ports of 10 gibt / s?

Hi,

First, the image is the view of an existing trunk.

Try the 'create trunk' button at the upper right and select the 10Gbe ports.

EDIT: You will have to delete the portals on the ports before you will be able to create a trunk on them. That is, ports 5 and 6 on both controllers have portals on them and are currently unavailable for trunking because of this.

You can't mix 1Gbe and 10Gbe ports in a trunk, and a trunk can't span across controllers. You can create a 10Gbe trunk, but only with the 2 10Gbe ports on a controller.

Also, you should not mix trunking and MPIO.

And creating a trunk with only one port connected is useless.

Given the ethernet connections you have there's no point in using trunking, but you can get failover in MPIO.
