4. Ryerson University, Computer & Communication Services (CCS), Technical Support Group The Challenges

5. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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. Ryerson University, Computer & Communication Services (CCS), Technical Support Group The Solution

7. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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 VMware VI3

13. Ryerson University, Computer & Communication Services (CCS), Technical Support Group VMware Update Manager * Note: RHEL guests can only be scanned, not remediated 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 OFFLINE Update Manager ESX Host Server

14. Ryerson University, Computer & Communication Services (CCS), Technical Support Group Resource Pool Update Manager VMotion 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 ESX Server Patching with Update Manager & DRS

22. Ryerson University, Computer & Communication Services (CCS), Technical Support Group Key Benefits

23. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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. Ryerson University, Computer & Communication Services (CCS), Technical Support Group Special Considerations

25. Ryerson University, Computer & Communication Services (CCS), Technical Support Group 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
