Agenda

• Infrastructure Design• Analyze Customer Requirements• Hardware requirements• Server configuration• Network recommendations• Virtual vs. Physical

• SQL Server Performance• Pre-grow vs. Auto-growth • I\O requirements• Sizing recommendations• Database Isolation

• SharePoint Server Performance• Tier isolation vs. Location Proximity Requirements• Load balancing your App Tier• Load testing in your environment• Governance & Troubleshooting


Infrastructure Design

• Analyze Customer Requirements• High Availability• Disaster Recovery• Budget Constraints• Location Awareness• Number of Concurrent Users


Infrastructure Design• Hardware requirements• Web servers & Application servers

• SQL servers

• What constitutes a small/medium/large farm?

Developer or Evaluation environmentsCPU: 4 cores, 64-bit required

RAM: 4GB Hard Drive space: 80GB

Production in Single Server or farm environments

CPU: 4 cores, 64-bit requiredRAM: 8GB

Hard Drive space: 80GB

Small FarmCPU: 4 cores, 64-bit

requiredRAM: 8GB


Medium Farm CPU: 8 cores, 64-bit

requiredRAM: 16GB


Large FarmUp to 2TB Content DBS

RAM: 32 GB From 2TB to 5TB Content DBS

RAM: 64 GB


Infrastructure Design• Server configuration – Small Farm


Infrastructure Design• Server configuration – Scaled Farm



• Network recommendations• Traffic Isolation• Web• Database• Search• Service Applications• Authentication

• Number of NICs per server• Limit the number of hops• Colocation of servers



• Physical• Benefits• No virtualization overhead• Ability to target DBs to separate physical spindles • Only OS limits on Hardware• Simple Networking

• Drawbacks• Backup & recovery time• Limited snapshot ability• Costly & lacking Centralized Management• Failover limitations



• Virtualization• Benefits• Snapshot capability• Rapid system deployment• HA\DR ability • Centralized Management

• Drawbacks• Loss of minimum 8% compute for overhead• Limitations on addressing full hardware• Disks are stored as single/multi-file • Centralized Networking


SQL Server Performance

• Pre-grow databases• Requires more space initially• Dramatic increase in performance• Databases like contiguous space

• Auto-growth • Immediately change from 1m increments• Do not use “Grow by %” setting• 50-100m maximum growth per required• Schedule maintenance task to check size & grow in off

peak hours as required



• I\O requirements DB Files RAID Level Optimization

1 TempDB data 10 Write

2 TempDB logs 10 Write

3 ContentDB data 10 Read\Write

4 ContentDB logs 10 Write

5 Crawl DB logs 10 Write

6 Crawl DB data 10 Read\Write

7 Property DB logs 10 Write

8 Property DB data 10 Write

9 Services DB logs 10 Write

10 Services DB data 5/10 Read\Write

11 Archive Content DB 5 Read

12 Publishing Site Content DB 5 Read



• Sizing recommendations• Recommended limit for ContentDBs: 200G• Maximum supported: 4TB

• Includes Remote BLOBs

• Backup/Restore timing• Simple vs. Full recovery mode



• Database Instance Isolation• Secure Store Database• SharePoint core databases• Content Databases• Search• Highly Transactional non-SharePoint DBs

• Drawback• Lose the central management in a single SQL Server

Management Studio window


SharePoint Server Performance

• Tier isolation vs. Location Proximity Requirements• Separation via vLAN• Less chatter• Increased hop count

• Collocating SharePoint in a single vLAN• Increased chatter• Lower hop count

• Key take away• Know your network, determine your topology based

upon traffic & requirements



• Load balancing your App Tier• Know your load• Scale based upon need, not perception

• Find your choke point, then release the grasp

• Don’t assume, validate!



• Load testing in your environment• Example• 2 Web Servers (4cores, 16GB RAM) using NLB• 1 App Server (4cores, 16 GB RAM)• 1 SQL Server Instance (16cores, 128GB RAM)

• Simple CRUD operations• Login, create list item, open item, modify item, save item,

delete item, log out



• Load testing in your environment• Results• Farm was completely non-responsive at ~500 concurrent

users• Root cause• Watching this test on the server side we found that we were

immediately CPU bound • Conclusion• Add CPUs or Web Servers to the farm to handle additional

load



• Governance & Troubleshooting• Determine tolerance for custom solutions• Encourage Sandbox Solutions

• Require SPDisposeCheck• Require SPMonitored Scope • If you don’t have a Dev/QA Environment, you don’t have

a Production Environment• Never test patches in Production• Educate on the Developer Dashboard



• Governance & Troubleshooting• Never accept a solution that is not a WSP• Respect your users, or you won’t have any• Limit the number of Farm Admins• Minimize Server Sprawl• Audit your environment regularly• Survey your users regularly• Engage your Executive Sponsorship
