Architecting the FarmUnderstanding the Three Tiers of SharePoint Infrastructure

• ‘All-in-One’ (Avoid)

DB and SP Roles Separate

Architecting the FarmSmall Farm Examples

• 2 SharePoint Servers running Web and Service Apps

• 2 Database Servers (Clustered or Mirrored)

• 1 or 2 Index Partitions with equivalent query components

• Smallest farm size that is fully highly available

Architecting the FarmSmallest Highly Available Farm

• 2 Dedicated Web Servers (NLB)

• 2 Service Application Servers

• 2 Database Servers (Clustered or Mirrored)

• 1 or 2 Index Partitions with equivalent query components

Architecting the FarmBest Practice ‘Six Server Farm’

• Multiple Dedicated Web Servers

• Multiple Dedicated Service App Servers

• Multiple Dedicated Query Servers

• Multiple Dedicated Crawl Servers, with multiple Crawl DBs to increase parallelization of the crawl process

• Multiple distributed Index partitions (max of 10 million items per index partition)

• Two query components for each Index partition, spread among servers

Architecting the FarmScaling to Large Farms

• Previously a third party product ($$$$)• More reasonable pricing now• Highly tuned and specialized search

engine for SharePoint and also as an enterprise search platform

• Replaces SharePoint 2010 Native Search if used

• ‘Net new’ features built-in.

Virtualization of SharePoint Servers

• Dedicated hosts for SharePoint Virtual Guests• No Software on Host OS! (Except A/V or Backup)• Don’t overallocate memory (ballooning) or

Processor (2:1 ratio max)

Virtual Hosts

• Ensure proper amount of IO (0.75 IOPs / GB min, 2.0 IOPS/GB recommended)

• Allocate Passthrough/RDM disk for best perf• If using virtual disks, use fixed-sized, not

dynamically expanding

Disk

• Aggregate multiple NICs on host for the guest networks

• Allocate Passthrough/RDM NICs for best perfNetwork

• Web Role is best candidate, but be cautious if using multiple app pools (800MB/pool)

• Service App systems generally good candidates• Use caution with the database role!

Virtualization of SharePoint ServersVirtual Guest Processor and Memory Guidelines

Allows organizations that wouldn’t normally be able to have a test environment to run one

Allows for separation of the database role onto a dedicated server Can be more easily scaled out in the future

Virtualization of SharePoint ServersSample 1: Small Single Server Environment / No HA

High-Availability across Hosts

All components Virtualized

Uses only two Windows Ent Edition Licenses

Virtualization of SharePoint ServersSample 2: Two Server Highly Available Farm

Highest transaction servers are physical

Multiple farm support, with DBs for all farms on the SQL cluster

Virtualization of SharePoint ServersSample 3: Mix of Physical and Virtual Servers – Best Perf

Virtualization of SharePoint ServersSample 4: Scaling to Large Virtual Environments

• Processor (Host Only)● <60% Utilization = Good● 60%-90% = Caution● >90% = Trouble

• Available Memory ● 50% and above = Good● 10%-50% = OK● <10% = Trouble

• Disk – Avg. Disk sec/Read or Avg. Disk sec/Write

● Up to 15ms = fine● 15ms-25ms = Caution● >25ms = Trouble

• Network Bandwidth – Bytes Total/sec– <40% Utilization = Good– 41%-64% = Caution– >65% = Trouble

• Network Latency - Output Queue Length– 0 = Good– 1-2= OK– >2 = Trouble

Virtualization of SharePoint ServersVirtualization Performance Monitoring

1. Create new Virtual Guest (Windows Server 2008 R2)

2. Install SP2010 Binaries. Stop before running Config Wizard

3. Turn Virtual Guest into Template, modify template to allow it to be added into domain

4. Add PowerShell script to run on first login, allowing SP to be added into farm or to create new farm

End Result - 15 minute entire farm provisioning…quickly add servers into existing farms or create new

farms (Test, Dev, Prod) on demand

Data Management

• Start with a distributed architecture of content databases from the beginning, within reason (more than 50 per SQL instance is not recommended)

• Distribute content across Site Collections from the beginning as well, it is very difficult to extract content after the face

• Allow your environment to scale and your users to ‘grow into’ their SharePoint site collections

Data ManagementDistribute Data Across Content DBs and Site Collections

• BLOBs are unstructured content stored in SQL• Includes all documents, pictures, and files stored

in SharePoint• Excludes Metadata and Context, information

about the document, version #, etc.• Until recently, could not be removed from

SharePoint Content Databases• Classic problem of structured vs. unstructured

data – unstructured data doesn’t really belong in a SQL Server environment

Data ManagementBinary Large OBject (BLOB) Storage

• Can reduce dramatically the size of Content DBs, as upwards of 80%-90% of space in content DBs is composed of BLOBs

• Can move BLOB storage to more efficient/cheaper storage• Improve performance and scalability of your SharePoint

deployment – But highly recommended to use third party

Data ManagementGetting your BLOBs out of the Content DBs

SQL Database OptimizationContent Databases Distributed Between Multiple Volumes

• Break Content Databases and TempDB into multiple files (MDF, NDF), total should equal number of physical processors (not cores) on SQL server.

• Pre-size Content DBs and TempDB to avoid fragmentation• Separate files onto different drive spindles for best IO perf.• Example: 50GB total Content DB on Two-way SQL Server

would have two database files distributed across two sets of drive spindles = 25GB pre-sized for each file.

• TempDB is critical for performance• Pre-size to 20% of the size of the largest content

database.• Break into multiple files across spindles as noted• Note there is a separate TempDB for each

physical instance• Note that if using SQL Transparent Data

Encryption (TDE) for any databases in an instance, the tempDB is encrypted.

SQL Database OptimizationTempDB Best practices

• Implement SQL Maintenance Plans!• Include DBCC (Check Consistency) and either

Reorganize Indexes or Rebuild Indexes, but not both!

SQL Database OptimizationSQL Maintenance Plans

• Add backups into the maintenance plan if they don’t exist already

• Be sure to truncate transaction logs with a T-SQL Script (after full backups have run…)

USE CompanyABC_SP2010_ContentDB01;

GO

ALTER DATABASE CompanyABC_SP2010_ContentDB01

SET RECOVERY SIMPLE;

GO

DBCC SHRINKFILE (CompanyABC_SP2010_ContentDB01_log, 100);

GO

ALTER DATABASE CompanyABC_SP2010_ContentDB01

SET RECOVERY FULL;

GO

High Availability and Disaster Recovery

• Clustering is Shared Storage, can’t survive storage failure, makes Mirroring more attractive

• Clustering fails over more quickly• Mirroring is not supported for all

databases, but Clustering is• Both Clustering and Mirroring can be used

at the same time (Instance to Instance)

High Availability and Disaster RecoveryData Tier – Clustering vs. Mirroring

• Introduced in SQL 2005 SP1• Greatly improved in SQL 2008 and now SQL 2008 R2• Available in Enterprise and Standard (Synchronous only)

editions• Works by keeping a mirror copy of a database or

databases on two servers• Can be combined with traditional shared storage

clustering to further improve redundancy• SharePoint 2010 is now Mirroring aware!• Upcoming SQL 2012 has some great Mirroring

improvements (Multiple copies of databases, both asynch and synch, and read-only copies in remote!)

High Availability and Disaster RecoveryData Tier – SQL Database Mirroring

• Single Site• Synchronous

Replication• Uses a SQL Witness

Server to Failover Automatically

• Mirror all SharePoint DBs in the Farm

• Use a SQL Alias to switch to Mirror Instance

High Availability and Disaster RecoveryData Tier – Database Mirroring Model #1 – Single Site

• Two Sites• 1-10 ms

Latency max• 1Gb

Bandwidth minimum

• Farm Servers in each location

• Auto Failover

High Availability and Disaster RecoveryData Tier – Database Mirroring Model #2 – Cross-Site with HA

• Two Sites• Two Farms• Mirror only

Content DBs• Failover is

Manual• Read-only

High Availability and Disaster RecoveryNetwork Load Balancing

• Hardware Based Load Balancing (F5, Cisco, Citrix NetScaler – Best performance and scalability

• Software Windows Network Load Balancing fully supported by MS, but requires Layer 2 VLAN (all packets must reach all hosts.) Layer 3 Switches must be configured to allow Layer 2 to the specific VLAN.

• If using Unicast, use two NICs on the server, one for communications between nodes.

• If using Multicast, be sure to configure routers appropriately

• Set Affinity to Single (Sticky Sessions)• If using VMware, note fix to NLB RARP

issue (http://tinyurl.com/vmwarenlbfix)

• Best Practice – Create Multiple Web Apps with Load-balanced VIPs (Sample below)

● Web Role Servers• sp1.companyabc.com (10.0.0.101) – Web Role Server #1• sp2.companyabc.com (10.0.0.102) – Web Role Server #2

● Clustered VIPs shared between SP1 and SP2 (Create A records in DNS)• spnlb.companyabc.com (10.0.0.103) - Cluster• spca.companyabc.com (10.0.0.104) – SP Central Admin• spsmtp.companyabc.com (10.0.0.105) – Inbound Email VIP• home.companyabc.com (10.0.0.106) – Main SP Web App

(can be multiple)• mysite.companyabc.com (10.0.0.107) – Main MySites Web

SharePoint Installation

• Good to understand how to install SharePoint from the command-line, especially if setting up multiple servers.

• Allows for options not available in the GUI, such as the option to rename databases to something easier to understand.

• Use PowerShell with SharePoint 2010• Sample scripts available for download…

SharePoint InstallationSome Manual Service Apps Still Required

• Due to complexity and/or bugs, certain Service Apps will need to be manually configured in most cases.

• This includes the following:● PerformancePoint Service Application● User Profile Service Application● Web Analytics Service Application

SharePoint InstallationDocument the Configuration and Monitor Changes

• Document all key settings in IIS, SharePoint, after installation• Consider monitoring for changes after installation for Config

SharePoint SecurityInfrastructure – Sample List of Service Accounts

• When creating any Web Applications in Classic-mode, USE KERBEROS. It is much more secure and also faster with heavy loads as the SP server doesn’t have to keep asking for auth requests from AD.

• Kerberos auth does require extra steps, which makes people shy away from it, but once configured, it improves security considerably and can improve performance on high-load sites.

• Should also be configured on SPCA Site! (Best Practice = Configure SPCA for NLB, SSL, and Kerberos (i.e. https://spca.companyabc.com)

SharePoint SecurityInfrastructure – Enable Kerberos when using Classic-Auth

• Role Groups defined within Active Directory (Universal Groups) – i.e. ‘Marketing,’ ‘Sales,’ ‘IT,’ etc.

• Role Groups added directly into SharePoint ‘Access Groups’ such as ‘Contributors,’ ‘Authors,’ etc.

• Simply by adding a user account into the associated Role Group, they gain access to whatever rights their role requires.

SharePoint SecurityData – Role Based Access Control (RBAC)

• New in SQL Server 2008

• Only Available with the Enterprise Edition

• Seamless Encryption of Individual Databases

• Transparent to Applications, including SharePoint

SharePoint SecurityData - Transparent Data Encryption (TDE)

SharePoint SecurityData - Use SharePoint-Aware Antivirus (3rd Party or FPS)

• External or Internal Certs highly recommended

• Protects Transport of content• 20% overhead on Web Servers• Can be offloaded via SSL offloaders if

needed• Don’t forget for SPCA as well!

SharePoint SecurityTransport - Secure Sockets Layer (SSL) Encryption

• By default, traffic between SharePoint Servers (i.e. Web and SQL) is unencrypted

• IPSec encrypts all packets sent between servers in a farm

• For very high security scenarios when all possible data breaches must be addressed

SharePoint SecurityTransport – IPSec from Server to Server

SharePoint SecurityEdge – Forefront Unified Access Gateway

• AD RMS is a form of Digital Rights Management (DRM) technology, used in various forms to protect content

• Used to restrict activities on files AFTER they have been accessed:● Cut/Paste● Print● Save As…

• Directly integrates with SharePoint DocLibs
