Question regarding redundancy with Dell Powerconnect 6224


I have 2 Dell Powerconnect 6224 Switches. I am connecting these switches to 2 - iSCSI appliances along with various servers. My original intention was to have 2 switches - 1 for network/internet traffic and 1 for the iSCSI traffic. The servers I am connecting have dual redundant network cards and are using load balancing. THere currenty is 4 Servers and 2 iSCSI appliances that will be using these switches.

My question, using the two Dell Powerconnect 6224 switches along with VLAN, Link agregations etc... Is it at all possible for me to somehow set this up so I can have the links be redundant? I.E. 1 port from each of the servers connect to one port on each of the switches so if 1 switch dies, the connection still works?

Your assistance is appreciated.

The main problem that you will run into is mac-address hopping where your dual network cards may be trying to use the same virtual mac-address. You can quickly get into a situation where redundancy is to the point of rediculous and difficult to troubleshoot. Arp issues, spanning-tree issues, mac-table issues, etc.
If you use the 2 NIC's on the servers as independent links (not load-balance, not failover) with different IP subnet on each one, each connected to a different VLAN, life will be much simpler.

Thanks Irmoore,

That is exactly the solution that I can up with. Not the fastest solution, but works for failover which really is the purpose. Speed in this situation is more an afterthought. =)

Here's my $0.02 for what it's worth...
Typically the switch is the last thing you need to worry about. They usually just work for years. However, the Dell products are at the very low end of the price spectrum and you get what you pay for. Everyone I've known that has used the Dell switches has eventually thrown them out in favor of Cisco, Nortel or HP.  You really do get what you pay for.
