CISCO-6500: Switching Capacity Calculation - engine switching channels full duplex switching bandwidth per channel Bidirectional It is stated that Sup720 has 720G switching bandwidth which is calculated as the following algorithm: 18×20G×2 ＝ 720Gbps Due to hardware architecture, one 20G channel is for internal use. Only 17 channels can be used by users. Currently, only three interface modules (WS-67xx) can fully make use of dual 20G fabric channel to 720G SFM. Abundant Interface modules (WS-65xx and WS68xx) are only one or two 8G channels to 720G SFM, such that utilization of bandwidth is very low. Catalyst6500 series Competitive Comparison & Analysis

58. Competition With HP ProCurve A7500 How to compete with HP chassis DGS-8000 can support up to 160G bandwidth per slot, but HP A7500 only supports up to 48G bandwidth per slot and has poor performance in the status below: Without Fabric Mod 768, HP A7510 can’t reach 1,152G bps and will have low performance. Ex: With one engine and Fabric Mode 384, A7503E/A7506E can support 24G channel per slot; but A7510E only supports 12G channel per slot) HP A7503-S uses low cost chassis and supervisor engine (Only 12G channel per slot) DGS-8000 Line cards support L2/L3/MPLS/VPLS/IPFIX/IPv4/IPv6 and up to 8x 10GE ports per line card*. But for HP A7500 line cards: SA can’t support L3/MPLS forwarding SC can support L3 distributed forwarding but can’t support MPLS forwarding EA can support L3/MPLS distributed forwarding but can’t support IPv6 hardware forwarding Only SD/EA/EB can compete with DGS-8000. But SD only has maximum 8-port 10GE (1:2 blocking rate) and no MPLS support; EA only has 1-port 10GE and does not support IPv6; EB only has 4-port 10GE. Competitive Comparison & Analysis

59. Competition With HP ProCurve A7500 How to compete with HP chassis DGS-8000 supports BFD for static route/OSPF/VRRP. But for HP A7500, only EB cards support BFD HP A7500 Fabric Mod 384 Lite can’t support L3 forwarding. Even using two fabric cards, it cannot run continuous forwarding when one fabric card crashes because the L3 table in line cards must be refreshed. HP A7500 uses sFlow and Netstream for packet sampling. sFlow and Netstream has poor sampling performance. Netstream is not an international standard. DGS-8000 supports IPFIX which has better performance than sFlow. (When IPFIX is in use, suggest to adopt 8000-ASE-IPFIX) DGS-8000 uses new DRR (Deficit Round Robin) for scheduling which can handle packets of variable size without knowing their mean size. HP A7500 only supports WRR (Weighted Round Robin) which can not differentiate the video, voice or data packets. DGS-8000 has more competitive price then HP A7500, especially for A7510 with Fabric Mod 768 engine. Competitive Comparison & Analysis

The total cost for HP 8212zl is still a little higher. (see next page) HP ProCurve E8200zl Series switches do not support some features for advanced application, such as BGP, Policy-based routing, Ring Protection, DHCP Server etc. HP ProCurve E8200zl Series switches does not support dynamic IPv6 routing protocols.

62. Competition With HP ProCurve E8200zl How to compete with HP ProCurve E8200 chassis HP 8212zl series only provides 993.6Gbps switching capacity ; DGS-8006 series can provide up to 1.28T bps. HP 8200zl series only have 28.8Gbps from modules to backplane. It has high blocking rate for 4-port 10G modules. Many advanced features are missing like BGP Policy-based routing, Ring Protection, DHCP Server etc. You can easily spec HP chassis out in truly core application because its limited S/W functions. E8200zl is positioned in between D-Link DES-7200 & DGS-8000. For feature competition, use DGS-8000. For price competition, use DES-7200. Competitive Comparison & Analysis
