GBE2 to one uplink switch
I'm using 5 blade servers with two GBE2 switches.
On this GBE2 switches I reserved port 20 as uplink port. This port is connected to Cisco switch 2960. All servers are on the same network, so I'm using only default VLAN. I don't use interconnect between GBE2 switches.
Is it correct to connect two uplinks to one switch(I would like to escape network loop)? Should I setup trunking or anything like this?
Which is the best teaming mode for my environment - 2 GBE2 -> 1 switch?
Many thanks,
Branislav

Re: GBE2 to one uplink switch
Topology 3 is a ├в straight-through├в design providing a simplified architecture with maximum throughput (Figure 4). Spanning tree protocol is not required further simplifying this configuration. However, this topology has reduced availability; certain failures can cause partial to total loss of service with the greater possibility of a performance bottleneck.
The GbE2c Ethernet Blade Switch crosslinks are enabled in this configuration. These Gigabit Ethernet links permit management of both switches and access to all c-Class BladeSystem server NICs from any single GbE2c Ethernet Blade Switch uplink. The crosslinks may be left disabled in this configuration, but it is not advised. In this case, a failure of any one switch (whether GbE2c Ethernet Blade Switch or Catalyst 6509) would cause the loss of service to one half the NICs on each ProLiant server.
Topology 3 is ideal for network administrators who desire a simplified architecture that provides high levels of performance at the expense of some availability.

Re: GBE2 to one uplink switch
In this straight through design are uplinks from one GBE2 switch to one switch(6509) and from second GBE2 switch to another. Would be possible to connect uplinks from both GBE2 switches into one switch(probably as trunk)?
Thanks
