This session will explore what happens after server consolidation: Workload profiles change, usage patterns change, and resource utilization goes up and down. During this session, we will discuss how the storage footprint changes, and what used to be ideally optimized isn't anymore.

You will learn how to quantify the gap between resource allocation and actual usage, how to recover and redeploy excess capacity, and how to find common virtual machine configuration mistakes that can degrade overall performance.

    • Finding Virtual Coins in the Couch Mike Mckay mike.mckay@novell.com
    • Session Overview Today's Data Center Virtualization adoption rates The over-provisioned and under-utilized virtual farm PlateSpin Recon and the 4 Steps to Success ® Awareness, analysis and planning Virtual capacity management Identification of future bottlenecks, opportunities for reclamation, and configuration issues PlateSpin Recon Demo: Finding Virtual Coins 2 © Novell, Inc.

    • Today's Data Center
    • Today's Data Center 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 approximately 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 infrastructure (purchase more capacity (nodes) as needed) 4 © Novell, Inc. All rights reserved.
    • The Truth and Reality (of the Virtualization team) The Truth... A virtualization teams time is spent performing three (3) main tasks, day to day. Creating new virtual machines for the business users Day to day administration of the environment Performing and continuing to migrate the remaining physical workloads. 5 © Novell, Inc. All rights reserved.
    • The Truth and Reality (of the Virtualization team) The Reality... Optimization of the new environment was NOT their responsibility! Today, as Gartner Group stated in the December 2009 Data Center conference “The Global 500 has approx. 25% of x86 workloads virtualized, although the fastest growth area is SMB.” “By 2012 their will be approx. 58 Million virtual machines deployed” (with lot's more to add). 6 © Novell, Inc. All rights reserved.
    • Challenges with Virtual Infrastructures Am I getting the most ROI from my purchases? Can I achieve higher consolidation ratios and VM density? Can I rearrange VMs to free up virtual resources? Do I have more server consolidation opportunities? Which VMs are facing resource constraints? When will I need to purchase more virtual hosts, storage, etc.? Are my VMs using their allocated capacity? Can I right-size VMs to free up capacity? 7 © Novell, Inc. All rights reserved.
    • Goals for Data Center Optimization Some examples: Maximize data center efficiency Increase VM performance Find, reclaim and redeploy unused virtual capacity Make more efficient use of existing resources Postpone purchases of new resources Predict future resource needs 8 © Novell, Inc.

    • PlateSpin Recon Enterprise Overview ®
    • Awareness, Analysis and Planning Data collection, analysis and reporting for the What resources are in the data center Data Center Manager and IT Architect What workloads are running on those resources How effectively are workloads assigned to resources Planning and scenario modeling Workloads Resources 10 © Novell, Inc. All rights reserved.
    • Virtual Capacity Management Maximize virtualization investments by understating how your virtual resources are being utilized Correct configuration issues and right-size server resource allocation to better match the workload Create more space in your virtual environment and improve resource capacity Reclaim unused virtual resources and defer the cost of new server purchases 11 © Novell, Inc. All rights reserved.
    • Virtual Capacity Management Awareness of Available Resources Identification Virtualization Opportunities of Bottlenecks Capacity for Reclamation Management Configuration Issues Cost Saving/Avoidance 12 © Novell, Inc. All rights reserved.
    • The Ideal Virtual Environment Optimized Under/Over Utilized 13 © Novell, Inc. All rights reserved.
    • PlateSpin Recon: ® Understand Resource Utilization 1 Collect VM utilization 2 Identify bottlenecks 3 Right size and data over a standard and areas of adjust VM resources business cycle reclamation allocation to improve (30 days) the performance of available services. Supply Unused Server Resources Demand Virtual Machine 14 © Novell, Inc. All rights reserved.
    • Opportunities for Reclamation Supply Waste Demand Do I have resources assigned that aren’t being used? Do I have VMs that aren’t being used? Reduce waste, assign unused resources to new projects = Defer the purchase of new hardware 15 © Novell, Inc. All rights reserved.
    • Opportunities for Reclamation 16 © Novell, Inc. All rights reserved.
    • Identification of Bottlenecks Supply Supply Supply Demand + Demand = Demand When will aggregate supply exceed aggregate demand? What resource (CPU, memory, network, disk) have I run out of/ will I run out of next? Improve performance, satisfy service levels with existing hardware = Defer the purchase of new hardware 17 © Novell, Inc. All rights reserved.

Use VMware Tools processor and memory Tip 5: Be aware of 6. Disable the CDROM VM-to-host placement in VMware Tip 7: Virtual machine 2. Upgrade your CPU processors and memory 1. Upgrade your RAM Tip 8: Remove unneeded (more RAM) virtual hardware Source: www.petri.com Tip 9: Update VMware Tools Source: searchvmware.techtarget.com Improve performance, satisfy service levels with existing hardware = Defer the purchase of new hardware 19 © Novell, Inc.

    • Configuration Issues 20 © Novell, Inc. All rights reserved.
    • The 4 Steps to Success
    • 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 22 © Novell, Inc. All rights reserved.
    • 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) 23 © Novell, Inc. All rights reserved.
    • 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 24 © Novell, Inc. All rights reserved.
    • The 4 Steps to Success 4 Analyze and Report: Detailed reports and analytics on actual and projected system performance Recognize underused virtual hosts Pinpoint current capacity bottlenecks in virtual hosts and predict future ones Discover allocated but unused virtual resources Identify mis configured virtual hosts and VMs 25 © Novell, Inc. All rights reserved.
    • The Next Steps: Tracking and Billing the Virtual Environment
    • How to Successfully Manage Capacity What administrators need to know: Who is using your VMs? What are they using your VMs for? When will they be done with your VMs? Where are your VMs assigned to run? Develop standard VMs configurations, and identify VMs that don’t conform Charge users for their usage of the virtualization environment, at a minimum track who is using how much of your environment 27 © Novell, Inc. All rights reserved.
    • How to Successfully Manage Capacity IT Chargeback is a way that IT organizations allocate their costs to different business units based on usage of IT resources PlateSpin Recon measures resource usage for all virtual machines ® The Chargeback framework converts resource usage figures into billing vales over set time periods Network Disk Data CPU Data Data Each machine can have multiple raters. Raters can bu used for multiple machines. Rater 28 © Novell, Inc. All rights reserved.
    • How to Successfully Manage Capacity Raters associate resources (inventory data and/or monitored metrics) with a fee that may or may not be time dependent, examples: Each processor used by the workload will cost $100 Each MB of memory used, based on average daily use, will cost $0.01 Workloads are then attached to raters as applicable, examples: This workload will be attached to the “Processor Assigned” rater These Workloads will be attached to both the “Processor Assigned” and “Memory Used” raters Reports are then run to calculate the cost for each workload over a selected time period, examples: This workload costs $200 for the last month These workloads costs $300 for the last week 29 © Novell, Inc.
