Cisco 1921 vs 2921

[duncanuno]

Hi

All help and suggestions appreciated. I would like advice on which device would be most suitable (or alternatives although keep to a minimum to not muddy the waters)

We are building a secondary data centre infrastructure and require a router to manage the following

WAN

• 2 x EHWIC-2FE modules
• anticipated traffic is mainly web based, no voice, no serial links anticipated,
• Firewall/VPN to be managed by ASA 55xx device
• single Internet feed - ethernet 20M on 100M bearer
• dual EoMPLS feeds - ethernet 100M
  • these are site to site EoMPLS across fibre rings to primary DC {to be established later}
  • anticipate having a similar model router there however
    • plan for 2 routers with 1 x EHWIC-2FE for resiliency, additional Internet feed - each router to manage Internet and site to site link
  • these 2 site to site links are essential for asynchronous replication, so automatic failover is required (managed on same router or split risk across 2 routers?)

• Which is suitable for highest WAN to LAN throughput - need to cater for future expansion of traffic
  • Cisco 1921 is rated at 15 Mbps, others indicate 25Mbps (http://www.broadbandbuyer.co.uk/Shop/ShopDetail.asp?ProductID=10995)
  • Cisco 2921 is rated at 50 Mbps, others indicate 75Mbps (http://www.broadbandbuyer.co.uk/Shop/ShopDetail.asp?ProductID=10489)

LAN

• multiple subnets - 12 to 16 required, possibly more
• ability to route traffic across these subnets to multiple servers (virtual machines)
  • iSCSI SAN on separate LAN switch

Any/all options and suggestions considered

Regards

Duncan

Actually there are three intermediate models between these two - the 1941, 2901, and 2911, so you should evaluate these as well.

Attached the performance datasheet. You can evaluate it toegther with you Cisco partner, or reputable consulant, to make a decison.

Hey Duncan,  

   We have a similar setup and requirements.  What did you end up going with?  

Thanks,
