  1. Hochverfügbarkeit

  2. Agenda • Hochverfügbarkeit im LAN • Problembereiche • passive Ausfallsicherheit • aktive Ausfallsicherheit • Elemente der Netzwerksysteme • Design-Konzepte • Hochverfügbarkeit im Security-Bereich 3Com Confidential revb

  3. 3Com Technolgie Developement • New Technologies came up and still comming up • VoIP • Storage, iSCSI • Application CRM, UMM, CC • Security 3Com Networks are able to support every Service and Application in your network because of Open/Standard based Solution Wirespeed Switching with own ASIC Developement 3Com Confidential revb

  4. High Switching Perfomance vs. High Storage Performance • Why iSCI – iSCI is using the flexibility of SAN and the simplicity of NAS • Why 3Com – 3Com understands the needs and the requirments of a „state of the art“ Network • High availibility, resilience, redundancy • Administrator friendly managemet • Policy/Application/Sevice based switching • TCO/TCA, ROI – Standard based Technology which keeps you open to all sides of your network choosing the best of breed Application or Hardware 3Com Confidential revb

  5. Overview – Using ISCSI with YOUR current It-Infrastructure! Performance Resilience Holistic Management Resilience E- mail Filer CRM PSTN SCM SIP ISCI will reduce your Cost of Aquisition because of Using your existing Network Infrastructure 1000BaseX, 10GoE No cost for expensive Fiber Channels! XRN VCX Security XRN WAN / Internet Security Standards Based Performance IP Telephony 3Com Confidential revb

  6. Hardware Availability Network Availability Proactive Management Keys to Continuous Operation • Link Redundancy • Resilient Topology • Protocol Resiliency • Device Reliability • Power and Fabric redundancy • Device Management redundancy Application Availability • Application Prioritisation • Application Filtering • Fault Prevention • Fault Identification • Device and Network Reporting • Service measurement

  7. Erhöhung der MTBF • Redundante Netzteile • Redundante Lüftermodule • Lüfter- und Temparaturüberwachung 3Com Confidential revb

  8. Full Redundancy Advanced RPS ARPS – redundante Netzteile für Stackables 220V Main • 2 Betriebsarten • Managed Redundancy Mode • Full Redundancy Mode • SNMP Modul wird im Advanced RPS unterstützt Managed Redundancy Advanced RPS • Für zusätzliche Fehlertoleranz wird ein Y-Kabel eingesetzt 3Com Confidential revb

  9. Redundanzmechanismen • Layer 1 • Resilient Link • Layer 2 • 802.3ad Link Aggregation / LACP • IEEE 802.1D / 802.1w / 802.1s • Layer 3 • VRRP • Routing-Protokolle: OSPF, RIP, BGP etc. 3Com Confidential revb

  10. NICs - PCI Hot Plug • Reduce maintenance time and expense • Add and remove NICs without turning the server off • Benefits • Reduces maintenance time by eliminating power down and reconfiguration • No downtime because the server maintains network connections with other NICs in the Load Balancing group this is a footer

  11. NICs - Failover • Fault Tolerant Connections • Up to 8 redundant connections from server to network infrastructure • Continues to monitor downed link, will re-establish when available (“fail back”) • Works even with third party NICs and LOM solutions • Benefits • Higher server availability, reliable server access • Protection against NIC, switch, server, or cable failure this is a footer

  12. NICs - Load Balancing • Vorteile • Erhöhter Server-Durchsatz und kürzere Antwortzeiten bei den Applikationen • Zuverlässiger Zugriff auf die Server • Skalierbare Bandbreite 3Com Confidential revb

  13. Switch 4900 100/1000 SS4400 SS4005 Aggregated Gigabit Links SS4900SX SS4900 Link Aggregation • Parallel active links “bonded” as a single logical channel for greater performance • It is a Point to Point technology • Point to multipoint can be achieved with XRN Fabrics • Traffic is hashed across Aggregated links based on: • Source/Destination MAC address • Source/Destination IP Address • Source/Destination IPX Address • Automatic recovery of any failed link for redundancy • Transparent to Spanning Tree protocol and can participate in 802.1w • VLAN Configuration implemented on individual ports and aggregated links • Standardized by IEEE 802.3ad and LACP 3Com Confidential revb

  14. Edge Switch Stacking Stack-wide Link Aggregation provides downlink connectivity even if a switch/link fails 20Gbps Stacking Bandwidth per Link Resilient Stacking Cable protects Unit or Cascade Failure Advanced RPS Connection for Power Resilience 3Com Confidential revb

  15. VRRP und OSPF X XRN Subnet B XRN Subnet A Layer-3 Switch 7700 • OSPF provides rapid Link state based Fail over in the core • VRRP provides alternative resilience 3Com Confidential revb

  16. Second Fabric for Sub 1 Second Failover Uses Existing Modules Redundante Switching-Architektur im modularen System Local Switching Engine Secondary Switch Fabric Primary Switch Fabric 16Gbps Local Switching Engine 16Gbps Local Switching Engine 16Gbps Local Switching Engine 16Gbps Local Switching Engine 16Gbps Local Switching Engine 16Gbps 3Com Confidential revb

  17. Verteiltes Design-Konzept 10/100 10/100 Switch 4400 Workgroup Distribution Switch 4060 XRN Distributed Fabrics Building/Wiring Closet Aggregation LAG LAG 802.3ad Switch 4060 XRN DF Backbone/Campus Aggregation LAG Switch 4924 XRN DF Server Farm Aggregation 3C996B-T 3Com Confidential revb

  18. Mittleres Unternehmens-Netzwerk Switch 4400 Switch 4400 Switch 4924 Switch 4924 40x0 XRN Fabric Switch 4924 Switch 4924 3Com Confidential revb

  19. Verteiltes Unternehmensnetz / ‘Campus-wide’ GBIC Fabric Interconnect GBIC Fabric Interconnect OSPF/RIP/VRRP 3Com Confidential revb

  20. Agenda • Hochverfügbarkeit im LAN • Problembereiche • passive Ausfallsicherheit • aktive Ausfallsicherheit • Elemente der Netzwerksysteme • Design-Konzepte • Hochverfügbarkeit im Security-Bereich 3Com Confidential revb

  21. Out-of-band Management ports for application synchronization VRRP for interface failover 3COM Security Switch 6200 Mögliche Hochverfügbarkeitslösung • Interface Redundanz durch VRRP • Spezieller Hochverfügbarkeits-Port für Synchronisation der Applikationen • Cluster-Technologien 3COM Security Switch 6200 3Com Confidential revb
