  1. Server Virtualization & Disaster Recovery Eran Frank Manager, Technical Support Group efrank@ryerson.ca Ryerson University, Computer & Communication Services (CCS), Technical Support Group

  2. Case Studies & Speaking Events DELL Canada

  3. Agenda • The Challenges • The Solution • Key Benefits • Special Considerations • Q & A

  4. The Challenges

  5. The Challenges • Underutilized x86 servers • Limited space in the Data-Center • Increased cooling and energy costs • Slow provisioning of new servers • Limited HA & DR solutions

  6. The Solution

  7. Server Consolidation, Virtualization & DR • Two Active/Active Remote Data-Centers • VMWare Virtual Infrastructure 3.x • Blade Servers (Dell PE1955: 8CPU’s, 16GB) • SAN (EMC CX3) • Real-Time Storage Mirroring (EMC MirrorView) • Current Status: 140 VMs (88% Win, 10% Linux, 2% Netware) • Hosted Apps: Oracle, SQL, MySql, Citrix PS, AD, DHCP, DNS, IIS, SharePoint, Apache, File & Print, etc.

  8. Virtualization Readiness Assessment VRA Key Findings • Avg. CPU Utilization (9am – 5pm) : 1.85% • Avg. Peak CPU (9am – 5pm) : 6.33% • Avg. Memory Utilization (9am – 5pm): 5.7% • Avg. Disk Utilization: 22%

  9. VMware VI3 After Virtualization • Software independent of hardware • Multiple OS’s & workloads per physical machine Before Virtualization • Software tied to hardware • Single OS image per machine • One application workload per OS

  10. VMware VI3 Encapsulation - Entire state of Virtual Machine is encapsulated: Memory, disk images, I/O device state - Re-use or transfer whole VMs with a file copy vMotion - Zero-downtime Maintenance - Optimal Utilization

  11. VMware VI3 - Dynamic Resource Optimization Resource Pool • Automatic Farm-level resource balancing • Intelligent Placement

  12. VMWare VI3 HA SAN ESX1 ESX2 ESX3

  13. VMware Update Manager OFFLINE Automates patch management for ESX Server, Windows and RHEL virtual machines • Scans and patch online & offline VMs and online ESX servers • Snapshots virtual machines prior to patching and allows rollback to snapshot Update Manager ESX Host Server * Note: RHEL guests can only be scanned, not remediated

  14. ESX Server Patching with Update Manager & DRS Update Manager • Streaming ESX servers patching with zero down time to VMs • ESX server enters DRS maintenance mode, one at a time • VMs are migrated off, host is patched & rebooted if required • VMs are migrated back on • Next host is selected VMotion VMotion Resource Pool

  15. VMware VI3 – Virtual Center

  16. VMware VI3 - Secure Web Console Access

  17. Direct SAN Backup 1 VCB & vRanger • Take VM Snapshot • Mount SAN Snapshot • Backup VM images to local disk (short term) • Backup local disk to backup library (long term) • No load on servers • 24hrs backup window 2 3 Backup Agent

  18. Direct SAN Backup – vRanger GUI

  19. DR Physical Infrastructure

  20. The DR Concept (one way) Site Failure EMC MirrorView/Sync LUN-Based Replication Data-Center B(50%Prod&Dev) Data-Center A (50%Prod&Dev) ESX Farm ESX Farm Dark Fiber Target VMFS Source VMFS SAN SAN

  21. The DR Concept in Practice Data Center A Data Center B SAN ESX Servers ESX Servers SAN

  22. Key Benefits

  23. Key Benefits • Very fast server provisioning (15 minutes) • Consolidation Ratio: 11:1 (60% host utilization) • 90% reduction in # of physical servers • 80% cost savings in power & cooling • 65% cost savings per server • Simplified server management • End to end real-time monitoring • Cost-effective Disaster Recovery • Expected savings of $572K/3years

  24. Special Considerations

  25. Special Considerations • Get senior management onboard (do VRA) • Get your staff trained prior to project(VMware&SAN) • Get an experienced consultant on-site • Have a major vendor managing the project • Control growth of VM’s • Monitor fabric infrastructure (Brocade Fabric Watch) • Monitor SAN performance (EMC Navi Analyzer) • Post project - Annual Health-Check & DR POC • Believe in it – it’s working and we are enjoying every moment of it

  26. How it looks like.. The first 50 P2V’ed Servers Our new ‘virtual’ infrastructure
