4. Planning for Failover Clustering Failover Cluster: What is it and why do I need one?
Windows Server Failover Cluster:
A group of two or more interconnected servers working together to provide ‘High Availability’
High Availability:
Goal of high availability (HA) is to minimize downtime on systems, applications, services, , databases, files & printers

5. Planning for Failover Clustering Sources of Downtime
Data Corruption
Component Failure
Application Failure
Human Error
Maintenance
Site Outage

6. Planning for Failover Clustering What Happens in a Failover
Something is wrong!!
Private Network
Public Network

7. Planning for Failover Clustering Hardware: What do I need?
TechEd 2011

Planning for Failover Clustering Hardware: What do I need?
Servers: Two simple requirements for 2008 R2 Cluster Support
All components must have a logo
Storage (SAN, iSCSI Target)
Network Interface Card (NIC)
Host Bus Adapter (HBA)
* NIC Teaming Software
* MPIO/DSM (Multipathing Software)
Complete solution must pass Cluster Validation
* Optional. Multi-pathing and NIC teaming software are not required but can enhance fault tolerance.

8. Planning for Failover Clustering Hardware: What do I need?
Network:
At least two network paths between nodes that fail “independently” of one another
Multiple networks for added redundancy
Public Network *
Internal Cluster Network *
Hyper-V Live Migration & Management
iSCSI Network
Virtual Machine Network
DHCP or Static IP Addresses
NIC Teaming: Helps add redundancy
* Recommended requirements. Additional networks can enhance high availability and separate network roles

9. Planning for Failover Clustering Hardware: What do I need?
Shared Storage
Types of Supported Shared Storage
iSCSI
SAS
Serial Attached SCSI
Fiber
FCoE
Fiber Channel over Ethernet
NEW!

10. Planning for Failover Clustering iSCSI Target Software
Low cost block-level storage alternative to expensive SAN solutions
Provide shared storage for Hyper-V to enable high availability and live migration
Provide shared storage for applications hosted on a Windows Failover cluster
Microsoft iSCSI Software Target 3.3
iSCSI Target Software (Downloadable and FREE!!!!)

11. Planning for Failover Clustering iSCSI Target Software
Assign device to initiator
Create disk device as a *.vhd file
iSCSI
Initiator
Software
iSCSI Target Software
OS detects device as new local disk

12. Planning for Failover Clustering Software: What do I need?
Windows Server Version that supports Failover Clustering
Windows Server 2008 & R2 Datacenter (Core or Full)
Windows Server 2008 & R2 Enterprise (Core or Full)
Microsoft Hyper-V Server 2008 R2 – FREE!! (Core) R2 R2

13. Planning for Failover Clustering Clustering with Server Core
Higher Availability!
Removes non-critical programs from production servers
No Internet Explorer, Windows Media Player, etc.
Smaller “attack surface” and greater stability
Less servicing & patching
Fewer components installed means fewer components to fail
GUI management using Remote Server Administrator Tools (RSAT)

14. Planning for Failover Clustering “Sneak Peek”: Next Release Windows Server Core UI
Absolutely NO videos or photos!!!
Disclaimer: Any resemblance to the eventual appearance of future versions of the Server Core UI is purely coincidental

15. Planning for Failover Clustering
Create iSCSI Disks
demo

16. Planning for Failover Clustering Preparing Networks
Public
Static or DHCP assigned address
Default gateway
Private
IPv6 preferred or non routable IPv4
No default gateway
Separate physical path than public network

17. Planning for Failover Clustering Preparing Shared Storage
Online disk
Initialize disk as MBR or GPT
Create “New Simple Volume”
Format NTFS
Assign drive letter, mount point, or leave unassigned
Storage volumes or logical unit numbers (LUNs) exposed to the nodes in a cluster must not be exposed to other servers, including servers in another cluster

18. Planning for Failover Clustering
Presenting and Configuring iSCSI Disks
demo

19. Planning for Failover Clustering Putting the Parts Together
Server
Network Card
NIC Teaming
Host Bus Adapter
Multipathing
Storage
iSCSI Initiator

20. Planning for Failover Clustering Mitigating Single Points of Failure
The stuff on this slide
High Availability
Network
NIC Teaming
Redundant Switches
Storage
Hardware RAID
Switched Fabric
Multipathing
SAN Replication
Other
Backup Power Supply
Server Level Backup
Data Level Backup
The High Availability Equation

21. Deploying a Failover Cluster
Agenda
Planning for Failover Clustering
Deploying a Failover Cluster
Managing a Failover Cluster

22. Deploying a Failover Cluster Testing: How do I know it works?
Validation
Comprehensive set of tests to verify cluster functionality and compatibility
Provides actionable feedback to correct problems
More information
Validation not only ensures you are supported by Microsoft but also gives you confidence that cluster will work as designed if, and when you REALLY need it.
When should I run validation?
New cluster
Hardware change
Troubleshooting

23. Deploying a Failover Cluster
Cluster Validation
demo

24. Deploying a Failover Cluster User Rights
Creating cluster or adding nodes
Domain Admin
No additional rights required
Non-Domain Admin
Logged on to the domain with an account that has administrator rights and permissions on all servers in that cluster
Can be a Domain Users account that is in the Administrators group on each clustered server
Must be given the ‘Create Computer Objects’ and ‘Read All Properties’ permissions on the default Computers OU

25. Deploying a Failover Cluster Active Directory Accounts
Administrator logs on with account with appropriate rights and permissions, and runs cluster wizards.
Active Directory
Create Cluster wizard uses logged on account to create computer account for the cluster
Computer account with same name as cluster. Cluster Name Object (CNO)

26. Deploying a Failover Cluster Active Directory Accounts
Computer account for clustered service or application. Virtual Computer Object (VCO)
User logs on with account with appropriate cluster permissions, and creates highly available applications.
Active Directory
Services and Applications wizard uses Cluster Name Object to create another account.
Computer account with same name as cluster. Cluster Name Object (CNO)

27. Deploying a Failover Cluster Install and Configure Failover Clustering
TechEd 2011
11/14/2018
Deploying a Failover Cluster Install and Configure Failover Clustering
Add the Failover Clustering Feature through Server Managers’ ‘Add Features’ wizard
Run the ‘Validate Cluster’ wizard
Run the ‘Create Cluster’ wizard in FCM on one of the nodes
Create your HA App in Failover Cluster Manager using the ‘High Availability’ wizard
It’s all wizards
