SharePoint best practices dictate that a proper disaster recovery plan should be in place before the launch of your SharePoint farm. Standard methodologies related to disaster planning in SharePoint deal with the traditional type of scenarios where your datacenter is a smoldering hole in the ground. Processes such as SQL Server database backups or STSADM backups for site collections are often employed to cater to such scenarios. When something seemingly benign like a Secure Store Service Application corruption strikes, architects and administrators often come to the sad conclusion that a complete farm rebuild is their only recourse. Additionally the risks associated with the application of regular bi-monthly SharePoint Cumulative Updates and periodic service packs, all of which have no uninstall or undo features, also serve to increase the probability of experiencing an complete emergency farm rebuild at some point in an architect/administrator’s career. Long after a rebuild is completed and business has been restored to "almost" normal status, you’ll still be troubleshooting server configurations and tweaking the environment to get back to your pre-disaster level.
This workshop takes you through a dramatically new way of architecting your disaster plan. By applying the principles of this new methodology, you’ll dramatically cut down your disaster response time to the point of almost avoiding them entirely.

  • 43. Infrastructure Design• Hardware requirements ● Web servers & Application servers Developer or Evaluation environments Production in Single Server or farm CPU: 4 cores, 64-bit required environments RAM: 4GB CPU: 4 cores, 64-bit required Hard Drive space: 80GB RAM: 8GB Hard Drive space: 80GB ● SQL servers Small Farm Medium Farm Large Farm CPU: 4 cores, 64-bit required CPU: 8 cores, 64-bit required Up to 2TB Content DBS RAM: 8GB RAM: 16GB RAM: 32 GB Hard Drive space: 80GB Hard Drive space: 80GB From 2TB to 5TB Content DBS RAM: 64 GB• What constitutes a small/medium/large farm?
  • 44. Infrastructure Design• Server configuration – Small Farm
  • 45. Infrastructure Design• Server configuration – Scaled Farm
  • 46. Infrastructure Design
  • 47. Infrastructure Design• Network recommendations ● Traffic Isolation • Web • Database • Search • Service Applications • Authentication ● Number of NICs per server ● Limit the number of hops ● Colocation of servers
  • 48. Infrastructure Design• 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
  • 49. Infrastructure Design• Virtualization ● Benefits • Snapshot capability • Rapid system deployment • HADR 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
  • 50. 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
  • 51. SQL Server Performance• IO requirements DB Files RAID Level Optimization 1 TempDB data 10 Write 2 TempDB logs 10 Write 3 ContentDB data 10 ReadWrite 4 ContentDB logs 10 Write 5 Crawl DB logs 10 Write 6 Crawl DB data 10 ReadWrite 7 Property DB logs 10 Write 8 Property DB data 10 Write 9 Services DB logs 10 Write 10 Services DB data 5/10 ReadWrite 11 Archive Content DB 5 Read 12 Publishing Site Content DB 5 Read
  • 52. SQL Server Performance• Sizing recommendations ● Recommended limit for ContentDBs: 200G • Maximum supported: 4TB – Includes Remote BLOBs ● Backup/Restore timing ● Simple vs. Full recovery mode
  • 53. SQL Server Performance• 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
  • 54. 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
  • 55. SharePoint Server Performance• 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!
  • 56. SharePoint Server Performance • 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
  • 57. SharePoint Server Performance• 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
