We have some aging infrastructure and need to start budgeting next-gen.
* The network has several small routers as individual edges to peer=
s, WAN, SIP services.
* It has a couple 6509s as Internet edge (full tables, 2 carriers, =
no transit, simple policies)
* It has some Nexus 7K as an aggregation layer for all the server p=
ods
* It has some 6509s as a backbone to interconnect the aggregation l=
ayers and inter-site links.
* We do run VRFs/MPLS across our backbone with L3, L2 and L1 servic=
es. Nothing super fancy, but it's a requirement.
Two approaches:
1 - Look at ASR9010 (or something similar) to replace all of the above. Pro=
s: It has the density, it has features, port buffers, seems to have good gr=
anular virtualization, seems to have a good reputation amongst heavy users.=
Cons: It is very expensive fully populated and there is some oversubscript=
ion on the higher-density cards.
2 - Look at one solution to consolidate all edge routers and a separate sol=
ution to consolidate backbone/aggregation. Pros: Less density required at t=
he edge layers, so a cheaper solution is possible; Not requiring full BGP t=
ables and port buffers at the backbone/agg layer widens the selection a LOT=
considering the number of vendors with high-feature/high-density L3 switch=
es. Cons: Now we are looking at 4 boxes per data center rather than 2.
So... Is there something in the same class as the ASR9000s that also have a=
good reputation? Will need at least 48 ports of 10G, 24x1Gb, limited overs=
ubscription, good feature sets, not astronomically priced. If we can't find=
the perfect fit, we will just look at two separate solutions.
Also... has anyone used a CSR1000v or Vyatta VM-based solution on something=
like a Pluribus? I know you can run them on any server, but there are vend=
ors like Pluribus who integrate the server hardware with a full-feature phy=
sical switch. (Their E68 is the one we are considering) I'm assuming you ar=
en't going to get anywhere near the features and performance of an ASR9010,=
but... can you get close?
Thanks.
