Cisco NetApp VMware VMotion - Joint Solution presentation from Networkers Live (Barcelona, 2010)

1. Application Mobility Across Data Centers BRKGENPNL-2104 Joel T. McKelvey - Technical Alliance Manager, NetApp Ravi Neelakant - Technical Alliance Manager, VMware Thomas Scheibe - Director, DC Systems Marketing, Cisco

5. What is VMware's VMotion? VMotion TM is a feature of VMware’s ESX servers where a Virtual Machine can be migrated from one ESX Server to another one with no application downtime

17. VMware VMotion Requirements Network Requirements Storage Requirements ≥ 622 Mbps of bandwidth and ≤ 5 msec latency between ESX Servers The virtual disks of all the VMs are on VMFS/NFS data stores VMs have access to the same IP subnet and broadcast domain on source and destination ESX Servers The VMFS/NFS data store read/write for source and destination

30. Storage Architecture Comparison Storage Architectures Shared Storage VMotion Storage VMotion and VMotion Intelligent Data Management for LDVM Stretched or Clustered Storage for LDVM Description Single array visible to both sites using extended SAN or other extended storage network. Storage VMotion to move storage between datastores at different sites. VMotion immediately follows. At each site arrays present identical storage to hosts. Single canonical copy of data at origin. Data cached on non-origin arrays. VM granular. Arrays appear as single logical entity. Data moves and copies coordinated via management plane. Currently not VM granular. Performance over Distance Long distances result in high latency and poor performance. Works over long distances with performance issues during transfer. Supports extremely long distances Very Short (current implementations under 10KM) Storage Requirements Low. Single array. FC, iSCSI, NFS. No specialized storage required. Moderate. Multiple arrays. Storage systems must be present at all sites. Moderate. Multiple arrays. Storage systems must be present at all sites. Caching configured at all sites (zero size until filled). High. Storage systems must be present at all sites. Clustering may add complexity. Coherency and split-brain concerns. Granularity and full migration issues.

33. Joint Validation Test Server and Applications Application Server Configuration Stress Generation Tool Application Performance Metrics Microsoft SQL Server 2005 (64-bit) on vSphere 4.0 CPU : 4 virtual CPUs (vCPUs) Memory : 8 GB Storage : Approximately 300 GB ( NetApp FAS3100 ) OS : Microsoft 2008 64-bit server Dell DVD Store open source benchmark Orders per minute (OPM)

34. VM Migration Time Across Data Centers Application: Microsoft SQL with more than 11,800 orders per minute

35. VM Application Performance Less than 3% application performance degradation
