  1. SAN 101 From Out of the Box to a Working SAN Continues

  2. Avinash Rao Brocade Communications Senior Systems Engineer

  3. Name Services FSPF Routing Fabric OS Services Distributed Name Server • Standards-based network address assignment • Distributed across the fabric • Dynamic scalability • Automatic legacy device support Auto-discovery – zero administration and lower total cost of ownership • Scalability and Cascading • Any port to any port • Dynamic recovery • Dynamically configured routes • Self-discovery Highly redundant network with no single points of failure

  4. Advanced Fabric Services:Advanced Zoning • WWN Hardware Zoning • Simple administration • Secure access control • Provides security and flexibility (best of hard and soft zoning)

  5. 8 Gbit/sec trunk Advanced Fabric Services:Inter-Switch Link Trunking • ISL Trunking • 8 Gbit/sec logical links • Simplifies fabric administration and design • Maximizes bandwidth utilization • Increases high availability • Ensures predictable performance under load • Aggregates edge traffic

  6. Foundation technology for intelligent SAN traffic mgmt Configurable platform for future services Filter on several different fields in a frame Multiple simultaneous filters per frame No performance impact Route frame Brocade 3rd Generation ASIC Frame Filter Send to Service CPU Stream of frames Reject Frame Count Frame Filters for LUN Zones; Protocol Zones; WWN; Future Advanced Fabric Services:Frame Filtering™: Intelligent Traffic Mgmt

  7. Advanced Fabric Services:LUN Zoning • LUN Zoning • More granular than WWN • More efficient storage port use • Centralized LUN access control • Capable of spanning different storage types

  8. Traffic Target Port Traffic Initiator Port Advanced Fabric Services:Performance Analysis • Performance analysis • End-to-end statistics • GUI graph view • API-accessible • Range of information available

  10. SAN Disk StorageWhy use it? • Improved overall availability • Improve/Protect critical data • Increased disk utilization • Reduce data center rack/floor space • Reduce management costs as a % of storage costs • Non-disruptive scalability • Reduce/eliminate backup windows

  11. SAN Disk StorageHardware Characteristics • Modular, building-block design for flexible configurations (performance/capacity ratio) • User Configurable • High speed and capacity disk drives to meet specific application requirements • global, dynamic hot spares • Intermixed RAID levels • Cache • Host connectivity • Redundant, hot-swappable components • No SPOF • Online microcode upgrade, LUN expansion, LUN mapping

  12. SAN Disk StorageFully redundant solution • Critical components are hot swappable: • Controllers • Power supplies • Hard disk modules • Battery • Fan module • Fiber connection module • Cache • Non disruptive upgrade/maintenance: • Microcode upgrades • Parts replacement • RAID group creation • LUN addition • Unit addition

  13. SAN Disk StorageSoftware • Performance • Cache • Path failover/load balancing software support • Optimization software • Data Protection/Business Continuance • LUN Security software • Local volume mirroring software • Remote copying software • Management • Easy-to-use GUI or CLI Software • “Call Home” diagnostic services • SNMP, out of band management options for popular network and SAN management applications
