1 Server Consolidation ssessments with VMware Capacitylanner Rich Talaber

2 genda Evolution of the infrastructure Uncovering the opportunity Conducting the assessment The typical client Developing the strategy Managing objections Need to be changed by Rich

3 We Started With Shared Environments Nothing new Single OS Sometimes partitions Mixed workload redictable load Capacity planning discipline erformance tuning Design rigor 1 2 Operating System 3 4 D B M S 1 D B M S 2

4 The Transition Begins In the late 8s, prices started to drop Environments no longer shared Development accelerated Shift from operational excellence to market speed Shift from rigor of design to management of: Server names and WINS I addresses Cabling Subnets WINS Licenses

5 One Day, We Took a Breath We found hundreds, sometimes thousands of servers We found higher ratios of IT staff We had difficulty managing service levels We found unlicensed software We found security issues Costs out of control Servers not being utilized But it was the right thing to do!

6 What Lies Beneath? pproximately 4% of Windows servers are > 3 years old Rack space ower consumption Weight and BTUs The average utilization rocessor utilization: 6% Memory utilization: 5% Disk busy: 1% Disk capacity: 1% NIC busy: 1% 2 to 5% more servers than expected

7 The Impact of Excess Capacity More to: Secure atch Monitor Store, heat, cool and power Troubleshooting is more complex

8 Reason for Consolidation The Reasons for Consolidation Help Shape the ssessment Money hysical constraints Space Weight ower Service levels (infrastructure simplification) Migration from old to new Integrate acquired IT

9 Money Requires strong TCO and ROI analysis OG does not automatically capture: Date of purchase urchase price Lease amount Warranty information Determining what is actually possible Grouping

10 hysical Constraints The Typical Client Has Opportunity for Rack Optimization 4% of equipment is > 3 years old Utilization rocessor = 7% Memory = 5% NIC < 1% Disk throughput < 1% Multi-processors 1 way = 21% 2 way = 52% 4 way = 16% 8 way = 3%

11 Service Levels Need to Shift from Tactical Operations to Strategic Thinking Number of physical machines Number of operating systems Standardization rocesses Change management Service level agreements Quality assurance Charge back and options

12 Impediments to Consolidation Culture / politics Lack of accurate information Money Expertise cceptance of technology Lack of process eople s time

13 Successful ssessments Include ccurate assessment of: Customer needs Customer willingness Customer expectations Capacity: ll servers lan that includes: rocess creation / improvement Iterative capacity utilization improvement Internal marketing Supplemental expertise Standardization Maximum usage of existing infrastructure

14 Overall IT ssessment Standardization Versioning Service packs and patches Security Optimization Utilization Data center planning and more

18 Grouping of Servers pp Loc Dept Env Server SQL Fin 1 SQL SQL SQL SQL SQL B B HR ER CS pp pp Fin HR HR T T Will not cross boundaries by default Only two servers have the possibility of consolidation Consolidation ratio may be 15:14 ER T 1 ER 11 ER 12 CS 13 B pp T 14 B pp1 15

19 Combining Departments pp Loc Dept Env Server SQL 1 SQL SQL SQL T T Changing from physical ownership to capacity ownership VMware enables capacity management 11 servers have the possibility of consolidation Ratio may be 15:7 SQL B 6 B 15 SQL B T 5 B T 14

20 Combining Locations pp Loc Dept Env Server SQL 1 SQL 2 SQL SQL SQL SQL T Combining locations increases ratios due to economy of scale 14 servers have the possibility of consolidation Ratio may be 15: T 8 T 1 T 14

21 The Typical Client 4% of equipment is > 3 years old Utilization rocessor = 6% Memory = 5% NIC < 5% Disk Throughput < 5% Multi-processors rocessors % of Inventory 3% 42% 25% 3% Utilization 7% 6% 6% 5%

22 Environment Only Boundary pp Loc Dept Env Server We must retain the environmental boundary Service levels Security Business continuity Highest ratio 15:2 15 T 5 T 8 T 1 T 14

23 Dispose of Old Servers Since June, the average number of servers 7MHz or less is 28% The average rack size of a server with CU <= 7 MHz is 7 Client with 1 servers 28 with <= 7 MHz processors 196 rack units (approx. 5 Racks) 446 Watts/Hour average = 125 KW/Hr Just switching to blades 28 with 2.8Ghz processors 6 rack units 36 Blade 3 Watts/Hour = 18 KW/Hr Reduced cabling Improved manageability Virtualizing increases the opportunity even more

24 Test and Development Great opportunity for virtualization roves the technology is ready and prepares for next steps Consolidate servers that service infrastructure roves you willingness to consolidate yourself roves new technology Clients report that 25% to 5% of their environment is test / dev / BC Consider concurrency What percentage of your test / dev servers are actively being used at any time? Could management software that schedules deployment of environments to a sandbox reduce requirements even further?

25 Like pplications Multiple physical servers to one single OS server Introducing Workload management Change management Quality assurance Chargeback SQL server consolidation on 64bit Still have control and service level issues Workload management software Virtualization

26 Mixed Workloads Virtualization Retain some control New production technology Multiple OS Sizing questions Mixed workloads on single OS DLL Conflicts

27 Optimization Optimize before you consolidate Could increase your consolidation ratio significantly SQL example 4 servers using 2 GB of RM each Optimize to use 1GB of RM each Double consolidation opportunity Comparative analysis nomaly detection Trend deviation

28 The Typical Server (1.7) 1276 MHz processors 2.6 GB RM on board / 1.5GB used % utilization approximately 7.2% Disk busy 5.6% rocessors % of Servers rocessor %

29 The Typical SQL Server (2.3)14 MHz processors/1.8gb RM % utilization approximately 7.3% Disk busy 5.7% Cache hit % = 99.7 Large consolidation opportunity rocessors % of Servers Trans/sec <2 Between 2 and 2 % of Servers >2 9

30 The Typical Exchange Server (2.2) 2188 MHz processors/1.7gb RM % utilization approximately 1.6% Disk busy 15.1% rocessors Directory cache 1 22 hit % = IS cache hit % = More memory needed ctive Users <2 Between 2 and 5 >5 % of Servers % of Servers

31 The Typical Citrix Server (2.1) 265 MHz processors 3.2GB RM installed/ 9MB used % utilization approximately 1.1% Disk busy 2.3% ctive sessions average = 8.4 Too much memory allocated rocessors ctive Sessions <1 Between 1 and 2 >2 % of Servers % of Servers
