4. Wide Area Data Services What it is and why it is important to you

5. PRODUCTIVITY COST SAVINGS DATA SECURITY The challenges that distributed enterprises face today

6. The CIO’s dilemma: Business performance or more control? • Increasing distribution of organizations • 88% of employees work outside of headquarters • IT must deliver to users guaranteed performance • Branches are expensive and difficult to manage Increasing control of data • Data Protection – WAN backup and DR • Security – SSL encryption • Consolidation – eases cost and management

10. WDS Optimisation Trends WDS Optimisation

11. Distributed computing problems are converging • Networking problems • Need “more bandwidth” • Latency is a secret throughput killer • Important applications not prioritised Storage Tape Backup Filers Tape Backup WAN BRANCH OFFICE DATA CENTER File Servers Mail Servers Filers Mail Servers File Servers Web Servers • Storage problems • Data sprawl • Islands of storage • Backup & replication • Compliance worries • Application problems • Web, e-mail, FTP, Notes, ERP, database, etc… • Slow response times • Apps often not used…too slow

12. The three root causes of poor wide-area application performance Not enough bandwidth Transport protocol chattiness Application protocol inefficiencies If you don’t solve all three, users won’t see performance benefits.

13. Technology Solution Data Streamlining • Reduce bandwidth needs • Prioritises applications’ bandwidth use Transport Streamlining • Reduce TCP chattiness and latency • Accelerates SSL encrypted traffic Application Streamlining • Reduce application chattiness and latency Management Streamlining • Enables transparent deployment and central management of WDS appliances WDS needs to address all key performance issues Root Cause Bandwidth Limitations Transport Chattiness and Latency Application Chattiness and Latency

14. Latency and Chattiness: Root Causes of Poor PerformanceMore Than a Bandwidth Problem LatencyTime required to traverse the network WAN BRANCH OFFICE DATA CENTER Chattiness Interactions required to complete an operation or data transfer WAN BRANCH OFFICE DATA CENTER

15. Wide-area Data Services (WDS) is an integrated approach Networking Overcome bandwidth and latency constraints Applications LAN-like WAN performance Storage Consolidate and simplify

16. WAN The WDS underlying framework Initiate new TCP sessions Maintain TCP sessions Maintain TCP sessions DATA CENTER BRANCH OFFICE 1. Accelerate the applications that are most important to your business • Accelerate all TCP-based applications • Prioritize all applications • Orders of magnitude improvements 2. Make it simple to deploy and manage • Transparent deployment • Auto-discovery, auto-interception • No changes to clients, servers, or applications • No tunnels • Robust central management

17. Data Streamlining provides multiple bandwidth optimisations • Eliminate redundant data on the WAN • 60 – 95% reduction in bandwidth utilisation Data Reduction • LZ-Compression for “new” data segments • Useful for data transferred on first pass Compression • (Optional) Prioritize data on bandwidth and latency • Compatible with existing QoS implementations QoS

18. WAN Application streamlining overcomes application protocol limitations Typical application inefficiency Open FID Read 1 Read 2 BRANCH OFFICE DATA CENTER

19. WAN Appliance completes transaction locally Appliance completes transaction locally Application streamlining overcomes application protocol limitations Request Optimized WAN Transfer BRANCH OFFICE DATA CENTER The net effect is 65-98% reduction in WAN round trips

20. Application streamlining overcomes application limitations CIFS • Windows File Sharing & Windows-based applications NFS • Unix File Sharing & Unix-based applications MAPI • Microsoft Exchange HTTP • Web-based applications HTTPS • Secure Web applications MS-SQL • Database driven applications BACKUP & REPLICATION • Simplified replication of remote servers PROXY FILE SERVICE • Disconnected operations & integrated file sharing

21. Data WAN Make TCP payload bigger 16KB to 100KB+ Repack payload with references References New data From 100KB+ to Virtual 1MB+ Transport streamlining overcomes TCP limitations The net effect is a 60-98% reduction in round trips BRANCH OFFICE DATA CENTER

22. Transport streamlining provides many more TCP optimisations SSL Acceleration • Supports end-to-end acceleration of secure traffic • Maintains the preferred trust model Advanced TCP Acceleration • “Fill the pipe” for OC12 and larger connections • Works with clean or lossy links (HS-TCP and MX-TCP) Connection pooling • Eliminate 50% of overhead for small, short-lived connections Adaptive congestionwindows • Adapt transfer parameters based on network characteristics Limited and fastretransmits • Ensure priority handling for packet resends

23. MX-TCP: Making WAN-based backup, replication, and transfers even faster MX-TCP Regular TCP High-Speed TCP Bandwidth / Throughput Time Works well for lossy environments and satellite WANs too

24. WDS approach accelerates all TCP applications – what to look for

25. WDS appliances should be designed for easy network integration • Wide range of models for data centers down to small offices • Up to 1,000,000 concurrent connections • Up to 4Gbps optimized bandwidth Scalability • Numerous 10/100/1000 in-path interfaces • TCP connection forwarding • Diverse in-path and out-of-path deployment options Deployment Flexibility • Serial clustering • Parallel clustering • Hot backups Software-based Redundancy • Fail-to-wire Ethernet cards • Multiple power supplies • RAID Hardware-based Redundancy

26. Request Temporary Session Key WAN Secure application acceleration that maintains the preferred trust model Optimized WAN transfer over SSL BRANCH OFFICE DATA CENTER Secured connection SSL session setup • SSL Certificates and private keys copied to server-side appliance (no certificate faking in branch offices) • Appliances use their own identity certificates to establish a secure connection (proactive or on-demand) • On secure data request, client handshake with server is intercepted by server-side Appliance. Server-side Appliance SSL connection with origin server. • Server-side Appliance establishes SSL connection with client. • Temporary session key is migrated from server-side Appliance to client-side Appliance, moving client’s SSL connection to client-side Appliance. • Transfers are accelerated via all OS streamlining mechanisms Legend SSL Certificate TemporarySession Key Secured connection

27. Enhanced Auto-Discovery • Simplifies deployments for complex environments • Automatically finds and optimizes between most distant Appliance pair • Eliminates the need for manual peering rules • Requires no additional configuration • Supports unlimited Appliances in transit between Client Appliance and Server Appliance • Improves performance • finds optimal Appliance pairing for maximum optimization BRANCH OFFICE DATA CENTER

28. WAN WAN WDS vs. application front end (AFE) devices • Web only • Single sided (no advanced data reduction) • Allows internet & branch connections Web Server Web BRANCH OFFICE DATA CENTER Application Front End (AFE) HTTPS INTERNET USER Backup File, Email, Filer, Web, SMS, etc… Web Files Email DB BRANCH OFFICE • Accelerate all applications • Data reduction • TCP optimization • Application layer optimization • 60 – 95% bandwidth savings • QoS Custom Apps DATA CENTER WDS
