Hello all,
I'm trying to price and buy a network setup for a high-availability
GigE situation that requires link aggregation. In a simplistic
example, my need is to have, Host A with 2 GigE NICs (copper) that are
link aggregated with 802.3ad but each "side" is run to a different
switch with a host Host B on the other side configured in the same
manner. For example:
++
/--| GigE Switch 1 |--\
| ++ |
/ \
NIC1-/ \-NIC1
HOST A -= =- Host B
NIC2-\ /-NIC2
\ /
| ++ |
\--| GigE Switch 2 |--/
++
In this example, Host A would have an IP of 10.0.0.1 that would be
aggregated on both NIC1 and NIC2 to provide 2Gbps through put and Host
B would have 10.0.0.2 with link aggregation. The theory to this being
that I can kill two birds with one stone and provide 2Gbps throughput
while having the high-availability. If Switch1 dies, throughput drops
to 1Gbps but the endpoints are still available and vise-versa.
If I'm understanding 802.3ad properly, the aggregates have to be on the
same switch or at least in the same "stack" and can't be passed along
on-wire in the same way that other tagged protocols can (such as VLAN
tags). Maybe I'm wrong on this? As usual, cost is a MAJOR constraint
(when isn't it?!?) and I'm looking for the cheapest possible solution.
Can anyone recommend a product/products that would accomplish this for
me? I'm trying to keep the price < $6000 if possible. If you feel
this is off-topic, please feel free to reply to me personally.
Thanks a lot in advance!
