Team,
I am trying to design a data center network and debating if I should use
which one of the solution? Any suggestions/recommendations?
Solution # 1: Use IPMP on Solaris hosts. Have one NIC0 physically go to
SW1 and NIC1 go to SW2. SW1 and SW2 are cisco switches clustered
together behaving like one large switch.
Solution # 1: Use Sun trunking
1.3(http://vegdave.wordpress.com/category/technology/sun/solaris-10/trunking/sun-trunking-13/)
on Solaris hosts. Have one NIC0 physically go to SW1 and NIC1 go to SW2.
SW1 and SW2 are cisco switches clustered together behaving like one
large switch. Then configure cisco side accordingly with LACP ether channel.
I always used Solution # 1 in my previous designs because of comfort
zone and I know it works. However Solution # 2 would get me following
benefits.
1. No failover delays because it doesn't have to rely on spanning tree
convergence
2. When both links are up, I get double the bandwidth.
The concerns:
1. Are there serious bugs for trunking 1.3 when operating with Cisco
switches? Some times cisco do things differently that drives systems nuts.
2. Are there any known issues with Sun Clusters or Veritas Clusters and
Sun Trunking 1.3? Logically thinking, it should be totally transparent
to the clusters but you might know that better.
Thanks in advance,
--
