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)


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.


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).


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?


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

PlateSpin® Recon Enterprise Overview


Awareness, Analysis and Planning

Data collection, analysis and reporting for the Data Center Manager and IT Architect

What resources arein the data center

What workloads are running on those resources

How effectively are workloads assigned

to resources

Planning and scenario modeling Workloads Resources


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

PlateSpin® Recon:Understand Resource Utilization

Supply

Demand

Unused Server Resources

Collect VM utilization data over a standard business cycle (30 days)

Identify bottlenecks and areas of reclamation

Right size and adjust VM resources allocation to improve the performance of available services.

Opportunities for Reclamation

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

Opportunities for Reclamation


Identification of Bottlenecks

Demand+ =

Improve performance, satisfy service levels with existing hardware = Defer the purchase of new hardware

When will aggregate supply exceed aggregate demand?

What resource (CPU, memory, network, disk) have I run out of/ will I run out of next?


Identification of Bottlenecks



Improve performance, satisfy service levels with existing hardware = Defer the purchase of new hardware

Tip 2: Improve your host's processor and memory

Tip 5: Be aware of VM-to-host placement

Tip 7: Virtual machine processors and memory

Tip 8: Remove unneeded virtual hardware

The 4 Steps to Success



Install: PlateSpin® Recon Enterprise in the data center

Installed on dedicated collector servers

No agents

Data remains on site

1



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)

2



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



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

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



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 machinesThe Chargeback framework converts resource usage figures

into billing vales over set time periods

Disk Data CPU Data NetworkData

Rater

Each machine can have multiple raters.Raters can bu used for multiple machines.



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
