1 Top 10 Non- SharePoint Technical Issues That Can Doom Your Implementation Robert Bogue (317)

2 Agenda Background Categories Do the Top 10 thing Close out

3 My Background Memorized the pinout of an RS- 232 serial connection Assembled computers when memory was chips and not sticks Ran Ethernet when it was coax Built servers when SCSI was a dirty word and RAID was used to get rid of bugs

4 My Present 13 Microsoft MVP Awards Author credit on 25 books Passionate about driving business value

5 Issue Types Performance Functionality Reliability

6 Performance

7 Functionality

8 Reliability

9 Abandonment

10 0. SQL Server Performance What You ll See Slow performance across the board Long search crawl times What s Wrong SQL Server is the bottleneck in SharePoint implementations What to Check SQL Server Buffer Manager: Page Life Expectancy > 300 (seconds) What to do Add memory Add memory Improve disk performance Add another SQL instance

11 Platter Head Arm

12 Around the mulberry bush

13 It Bugs Me! RAID 1+0 RAID 5 A1a B1a C1a D1a A1b B1b C1b D1b A2a B2a C2a D2a A2b B2b C2b D2b A1 B1 C1 Dp A2 B2 Cp D1 A3 Bp C2 D2 Ap B3 C3 D3 Disk 0 Disk 1 Disk 2 Disk 3 Disk 0 Disk 1 Disk 2 Disk 3

14 Physics are Physics Even if you don t want them to be.

15 . SAN Configuration What You ll See Slow performance, especially initial loading of a site Less effectiveness in adding RAM to the SQL server What s Wrong Disks aren t producing enough IOPS What to Check Average time per read < 20ms Average time per write < 20ms RAID configuration is RAID 10 not 5/6 (DP) What to do Reconfigure from RAID 5/6(DP) to RAID 10 Buy more, faster, smaller disks (or SSD)

16 Storage and Speed

17 . Load Balancer Configuration What You ll See First hit response times, even after the first hit What s Wrong The load balancer isn t configured for session affinity (sticky sessions) What to Check Session affinity Session identification What to do Configure the load balancer for session affinity (sticky sessions)

18

19 . SharePoint Server Disk What You ll See SharePoint Server disks get filled up What s Wrong The full text (non-sql) indexes get copied to every query server (and they re big) What to Check Every query server has 30% of the total size of everything you want to search What to do Add disks until you have enough

20 . Core Network What You ll See Weird SharePoint errors Erratic and unpredictable performance What s Wrong Insufficient bandwidth between servers Packet loss What to Check No Firewall between servers Network adapter transmit buffer < 1 What to do Remove firewall and proxy servers between SharePoint and SQL Ensure all network ports plugged in and bonded Plug all SharePoint servers into a single switch

21 Virtualization

22 . Lack of Quality What You ll See Unknown problems in your production environment What s Wrong There s no way to validate your code and configuration changes What to Check The value of downtime in production to the organization What to do Get at least one controlled environment before production

23 The Impact of Developers

24 . Crosstalk What You ll See Random outages in production Random performance issues in production What s Wrong Production is referencing development resources (which are being shutdown) What to Check Production can not communicate with development What to do Put production (and QA) on a separate subnet that can t talk to development resources

25 . Abstract IP What You ll See All clients look like they re coming from one IP address What s Wrong The proxy server or load balancer is NATing (abstracting) the IP address Difficult to diagnose specific client problems when you can t find them What to Check Configuration of the proxy server or load balancer IIS Logs to verify client IP addresses are being recorded What to do Reconfigure the network to transmit client IP addresses to the server

26 Split Path Networking

27 . Lack of Monitoring What You ll See Nothing What s Wrong You can t fix what you can t find What to Check Monitoring options available to you What to do Install monitoring Configure monitoring

28 . Login Prompts What You ll See Prompts for login (like every 30 seconds) What s Wrong IE with your web site not in the Intranet zone What to Check IE settings Time synchronization What to do Set a group policy Make workstations a member of the domain
