Why Virtualize?

• 4 Servers = 1 Hairdryer = 1.25kW

• 7,500 Servers = 2,250 kW

• 2,250 kW for one year = 19,710,000 kWh

• 19,710,000 kWh = 14,783 Tons CO2

• Trees scrub ≈ 50lb of CO2 each year

Our virtualization will have the same impact as planting 591,300 trees or taking 1569 Hummers® off our

highways

Alternatively - Why Virtualize?

The Division’s technology infrastructure is growing annually at a rate greater than the revenue growth

infrastructure growth > revenue growth

41 – 92% growth in income in past 5 years

300 – 780% growth in infrastructure in past 5 years

Storage Optimization Potential• Appropriate Performance

– Currently 90% of storage is on high performance high cost disk

– Analysis shows over 60% of primary data is barely active

– High Performance disk is 300% the cost of new larger and slower technology

• Utilize unused storage– Currently storage is 31% full

– New technology allows better management allowing a shift to 60% utilized

– ½ of the storage is required to service the same amount of used space

What we can’t do•All dedicated and specialty storage frames were excluded, regardless of usage

•25% of the remaining applications were removed to be conservative

Impact•Results in expense saving due to reduction in capital equipment costs and associated depreciation

Technologies•Data Mobility and Mitigation

•De-duplication, cloning, thin provisioning

•Performance Monitoring and Alerting

•Capacity Reporting and Dash-Boarding

Server Virtualization Potential• Certain applications not candidates for ESX 3.5

– Golden Geese

– Large memory applications

– High performance databases

– Grid Architectures

– IO intensive apps

• Target first– Non production

– Windows, Linux

– Stateless/non-clustered

• Business unit specific goals– Analyze architecture of foot print

– Examine growth plans

– Negotiate goals

Server Virtualization Potential• Existing environment opportunity ≈ 4000 servers (36% x86)

• Organic growth opportunity ≈ 1000 servers annually (30%)

• Existing Servers – P2V– Cost per recovered kW ≈ 25% cost of equivalent datacenter capacity

– One time recovery of 1.3MW

– One time skill set • Vmware & NetApp professional services

– Ranging from 10:1 to 30:1 consolidation

• Growth Virtualization– Cultural /behavior change

– Acquire(d) skills - FTE

P2V – Existing Server Virtualization• Recovers datacenter capacity

– Space and power

– Unanticipated consequences – e.g. Decreases underutilized storage

• Refreshes servers– Decreases (repurposes) capital costs of hardware

– Opportunities for license recovery

– Provides HA to traditionally non-clustered environments

• Saves a boat load of money

Financial Impact of mitigation

• 5 Year cash savings in excess of $300M– Avoided datacenter expansion

– Reduced server capital

• Under 12 month payback

Sample of environment: 72 servers, 1728 CPU cores, 18TB RAM, Approx 2000 VMs

Big Rules for stability – Control failure domains

• RTO ≤ 15 minutes (single HW failure)

• Physical hosts per cluster 12 ≥ n > 3 (N+1 minimum)

• Most constrained resource (CPU, RAM, IO) ≤ 70% in normal conditions

• Separation of Non Production and Production VMs between clusters

• VMs per cluster ≤ 400

• VMs per storage devices ≤ 500

Technologies

• VMware VI 3 - ESX 3.5– vCenter, HA, DRS, vMotion, Storage vMotion

• Intel Xeon Series 7400 processors

• IBM System x3850 M2

• NetApp FAS 6080

• Cisco 10 Gigabit Ethernet

Cisco Technology Highlights and Futures

• Unified Computing System– Memory expansion - cheap DIMMs

– Network• Unified policy management (physical and virtual)

• Increased IO throughput, Integrated Nexus 1000

– Management complexity reduction• Unified/aggregated control points

– Energy efficiency • Decreased physical components

• Lower aggregate power consumption

• Nexus 1000, 5000, 7000– Unified fabric

• Data center Ethernet

• FCOE

– Cabling reduction

– Throughput improvements

– Reduced management complexity

Intel Xeon 5500 Series with UCS• 48 DIMMs• Max 384GB per Blade

Benefit•4x capacity•Lower costs•Standards DIMMs, CPUs, OS

Cisco UCS Memory

Each DIMM the CPU looks for is made of 4 standard DIMMs

Xeon 5500

Key learning's to date• Cost of mitigating growth through virtualizing existing infrastructure

25% cost of building new capacity

• Existing server virtualization (P2V) can be managed centrally– Funded centrally can provide upside to business units

– Leverage professional services

• Growth virtualization is a behavior change– Requires business buy in or mandate

– Requires changes in allocation/charge back

– Over communicate, Publicity, fame and shame all work

• Failure domain/scope management is crucial

• Manage bandwidth and IOps

• Watch the economics of RAM : Core ratio
