Consolidation Planning: Getting the Most from Your Virtualization Initiative

1,001 views

Published on

During this session, you'll get an in-depth look at the principles and best practices of planning a server consolidation project. You will learn how to ensure projects meet goals such as minimizing new hardware purchases or rack space, how and when to use different strategies such as scale up versus scale out, and how to prove those goals were met after the project is finished.

  3. 3. Today's Data Center
  4. 4. Virtulization in 2010 Most of the large and mid-tier enterprises are well along the path to virtualization Gartner Group stated in the December 2009 Data Center conference “The Global 500 has approx. 25% of x86 workloads virtualized” 2 common methods of implementing virtualization » Over provisioning of the virtual infrastructure (large initial investment) » Pay as you go virtual infrastrcture (purchase more capacity (nodes) as needed) Forrester research indicates typical server consolidation ratios of under 10 VM's per host initially. 4 © Novell, Inc.

  5. 5. Virtualization Adoption 31+ Vms per physical host 21-30 Vms per physical host 10-20 Vms per physical host <10 Vms per physical host Firms implementing ITIL Production systems virtualized Virtual server host utilization target Stage 1: Stage 2: Stage 3: Stage 4: Acclimation Consolidation Process Policies and Improvement Automation 5 © Novell, Inc.

  6. 6. Understanding Virtualization Adoption Stage 1: Acclimation Stage 2: Strategic Consolidation • Get comfortable with it as a concept and tool • Comfortable with concept, use, maturity, stability • Deploy for test/dev • Shift mindset from server to virtual server • Deploy for non-business-critical DR • Spread production deployments widely • Some production deployments – but tactical • Begin deployment for some business-critical DR • No change to operations processes • Painfully transition from server sprawl to virtual • Limited virtualization tool deployments server life-cycle management • Experimenting with Vmotion and Distributed Resource Scheduler (DRS) Stage 3: Process Improvement Stage 4: Pooling and Automation • Using Vmotion, starting to trust DRS • Trust DRS • Can utilization rates be increased? • Implementing production policies for automation • Deploy for business-critical DR • Some mission-critical DR deploys • Begin bifurcating applications between • Pooling and internal cloud development priority and non-priority • Chargeback/utility tracking • Developing new operational efficiencies • SLA and Qos focus • Process improvement spreading/butting up against network, storage, security, development 6 © Novell, Inc.

  9. 9. How Consolidation Planning Works? Identify consolidation candidates based on performance criteria Create consolidation scenarios to distribute workloads across target servers Evaluate scenarios based on TCO, space, power and utilization Maximize utilization and adjust resource allocation to meet consolidation goals Collect data (inventory or performance) for consolidation candidates (workloads) 9 © Novell, Inc.

  10. 10. Workload Profiling? The workload profile captures information about the encapsulated data, applications and operating systems residing on a physical or virtual host.

  11. 11. One Time vs. Ongoing Consolidation Planning One-time Continual • Aggressive • Conservative • Try to virtualize as much • Multiple rounds of as possible at once virtualization, select • Goal – maximum cost saving “lowest hanging fruit” • One-time project • Goal – successful • Low upfront cost technology adoption (sometimes free) (IT and end-users) • Risks • Persistent software • Hardware can’t support the (plan when you walk number of servers virtualized with the latest information) • Hardware can’t support the • Software has a cost type of workloads virtualized 11 © Novell, Inc.

  13. 13. The 4 Steps to Success 1 Install: PlateSpin Recon Enterprise ® in the data center Installed on dedicated collector servers No agents Data remains on site 13 © Novell, Inc. All rights reserved.
  14. 14. The 4 Steps to Success 2 Inventory: Discover and inventory every physical server, virtual host and virtual machine in the data center Server type, CPU type, number of cores Name, IP address, domain Operating system, patches, hotfixes, applications Services Storage (total and available) 14 © Novell, Inc. All rights reserved.
  15. 15. The 4 Steps to Success 3 Monitor: The resource utilization of each workload, physical server and virtual host for 30 days CPU utilization Storage utilization Memory utilization Network throughput Disk throughput Complete 24-hour profile, not just peak usage 15 © Novell, Inc.

  16. 16. The 4 Steps to Success 4 Analyze and Report: Detailed reports and analytics on actual and projected system performance “Good Consolidation Candidates” report Create consolidation scenarios with difference virtual host server models Set performance thresholds: 50% memory usage for example Project each scenario's server count, rack space usage, power consumption, cooling requirements, etc. Map physical servers to projected virtual hosts 16 © Novell, Inc.

  19. 19. Inventory Facts Server consolidation projects, tend to focus on Windows based platforms initially. – Low hanging fruit, servers nearing hardware lease, etc. Typically, servers with Local attached storage are prime candidates for server consolidation The smaller the number of cores and CPU's, the higher the consolidation ratio 19 © Novell, Inc.

  21. 21. Utilization Facts Most Under-Utilized resource in the data center is CPU – Typically, server candidates are running at less then 30 % CPU utilization Memory is the next most under utilized resource – Memory Dedupe, available in VMware vShpere, is only the first step. Network, and disk utilization vary significantly across environments – Not typically an issue for SAN based virtual infrastructures 21 © Novell, Inc. All rights reserved.
