  • 1. CloudBridge and Storage Solutions The killer app Gopinath Durairaj Director, Product Management, Citrix Cloud Networking Group Cedric Courteix Technical Alliance Manager, NetApp Global Alliances
  • 2. Citrix + NetApp joint solutions
  • 3. © 2013 Citrix | Confidential – Do Not Distribute Data Center Data Center (Backup) Storage Replication • Synchronous Replication  limited by latency • Asynchronous Replication  Periodic updates • NetApp SnapMirror • Uses multiple connections • Up to two per volume • Full volume or incremental replicates • Typical Replication Options • Nightly – finish within the assigned window • Continuous – co-exist with critical flows Storage
  • 4. © 2013 Citrix | Confidential – Do Not Distribute Replication Performance over WAN Latency • TCP sender transmits data upto the window size and waits for Ack • Round-trip time impacts utilization even if bandwidth is plenty Packet Loss • TCP dramatically reduces the window size when packets get lost • Slow ramp up back to the original window size Standard TCP Behavior
  • 5. © 2013 Citrix | Confidential – Do Not Distribute CloudBridge Optimization Technologies TCP Flow Control Compression Protocol Accelerators QoS AutoOptimizer™ Engine Application Mix Network Conditions Improve inefficient protocols Data compression / De-duplication Overcome loss/latency penalties Prioritize critical traffic   
  • 6. © 2013 Citrix | Confidential – Do Not Distribute TCP Flow Control Slow Start Slow Ramp Without CloudBridge Average Utilization Throughput Time With CloudBridge Average Utilization Throughput Time Link Speed Tight RPO  Less data loss with failures Adjusts for both latency and packet loss
  • 7. © 2013 Citrix | Confidential – Do Not Distribute QoS NetApp SnapMirror Bulk Transfers WAN Application Traffic Without CloudBridge 60% 20% 20% Bulk Transfers Application Traffic NetApp SnapMirror With Cloudbridge Application level granularity Deep classification, prioritization and shaping Run SnapMirror in shared links
  • 8. © 2013 Citrix | Confidential – Do Not Distribute CloudBridge with SnapMirror Issue SnapMirror SnapMirror + CloudBridge Low WAN utilization – due to latency, packet loss Increase window size to address latency Optimized window size + congestion behavior to increase WAN utilization Limited WAN throughput Native compression Offload compression to CloudBridge  increased file serving capacity Shared link with other critical traffic N/A Preferential treatment for high priority traffic and bandwidth allocation. Enable link sharing, running SnapMirror in background
