Problem

　　In a previous tip on SQL Server 2008 Installation Process, we have seen how different SQL Server 2008 installation is from its previous versions. Now, we have another challenge to>Solution
　　There have been a lot of changes regarding clustering between Windows Server 2003 and Windows Server 2008. It took quite a lot of effort for us to build a cluster in Windows Server 2003 - from making sure that the server hardware for all nodes are cluster-compatible to creating resource groups. Microsoft has redefined clustering with Windows Server 2008, making it simpler and easier to implement. Now that both SQL Server 2008 and Windows Server 2008 are out in the market for quite some time, it would be a must to prepare ourselves to be able to setup and deploy a clustered environment running both. Installing SQL Server on a stand-alone server or member server in the domain is pretty straight-forward. Dealing with clustering is a totally different story. The goal of this series of tips is to be able to help DBAs who may be charged with installing SQL Server on a Windows Server 2008 cluster.
　　Prepare the cluster nodes
　　I will be working on a 2-node cluster throughout the series and you can extend it by adding nodes later on. You can do these steps on a physical hardware or a virtual environment. I opted to do this on a virtual environment running VMWare. To start with, download and install a copy of the evaluation version of Windows Server 2008 Enterprise Edition. This is pretty straight-forward and does not even require any product key or activation. Evaluation period runs for 60 days and can be extended up to 240 days so you have more than enough time to play around with it. Just make sure that you select at least the Enterprise Edition during the installation process and have at least 12GB of disk space for your local disks. This is to make sure you have enough space for both Windows Server 2008 and the binaries for SQL Server 2008. A key thing to note here is that you should already have a domain on which to join these servers and that both have at least 2 network cards - one for the public network and the other for the heartbeat.>Windows6.0-KB942288-v2-x86.msu). These two are prerequisites for SQL Server 2008 and would speed up the installation process later on.
　　Carve out your shared disks

　　We had a lot of challenges in Windows Server 2003 when it comes to shared disks that we will use for our clusters. For one, the 2TB limit which has a lot to do with the master boot record (MBR) has been overcome by having the GUID Partition Table (GPT) support in Windows Server 2008. This allows you to have 16 Exabytes for a partition. Another has been the use of directly attached SCSI storage. This is no longer supported for Failover Clustering in Windows Server 2008. The only supported ones will be Serially Attached Storage (SAS), Fiber Channel and iSCSI. For this example, we will be using an iSCSI storage with the help of an iSCSI Software Initiator to connect to a software-based target. I am using StarWind's iSCSI SAN to emulate a disk image that my cluster will use as shared disks. In preparation for running SQL Server 2008 on this cluster, I recommend creating at least 4 disks - one for the quorum disk, one for MSDTC, one for the SQL Server system databases and one for the user databases. Your quorum and MSDTC disks can be as small as 1GB,>　　Present your shared disks to the cluster nodes
　　Windows Server 2008 comes with iSCSI Initiator software that enables connection of a Windows host to an external iSCSI storage array using network adapters. This differs from previous versions of Microsoft Windows where you need to download and install this software prior to connecting to an iSCSI storage. You can launch the tool from Administrative Tools and select iSCSI Initiator.

　　To connect to the iSCSI target:

• 　　In the iSCSI Initiator Properties page, click on the Discovery tab.
  
  
  
  
• 　　Under the Target Portals section, click on the Add Portal button.
  
• 　　In the Add Target Portal dialog, enter the DNS name or IP address of your iSCSI Target and click OK. If you are hosting the target on another Windows host as an image file, make sure that you have your Windows Firewall configured to enable inbound traffic to port 3260. Otherwise, this should be okay.
  
  
  
  
• 　　Back in the iSCSI Initiator Properties page, click on the Targetstab. You should see a list of the iSCSI Targets that we have defined earlier
  
  
  
  
• 　　Select one of the targets and click on the Log on button.
  
• 　　In the Log On to Target dialog, select the Automatically restore this connection when the computer starts checkbox. ClickOK.
  
  
  
  
• 　　Once you are done, you should see the status of the target change to Connected. Repeat this process for all the target disks we initially created on both of the servers that will become nodes of your cluster.
  

　　Once the targets have been defined using the iSCSI Initiator tool, you can now bring the disks online, initialize them, and create new volumes using the Server Manager console. I won't go into much detail on this process as it is similar to how we used to do it in Windows Server 2003, except for the new management console. After the disks have been initialized and volumes created, you can try logging in to the other server and verify that you can see the disks there as well. You can rescan the disks if they haven't yet appeared.
　　Adding Windows Server 2008 Application Server Role
　　Since we will be installing SQL Server 2008 later on, we will have to add the Application Server role on both of the nodes. A server role is a program that allows Windows Server 2008 to perform a specific function for multiple clients within a network. To add the Application Server role,

• 　　Open the Server Manager console and select Roles.
  
• 　　Click the Add Roles link. This will run the Add Roles Wizard
  
  
  
  
• 　　In the Select Server Roles dialog box, select the Application Server checkbox. This will prompt you to add features required for Application Server role. Click Next.
  
  
  
  
• 　　In the Application Server dialog box, click Next.
  
  
  
  
• 　　In the Select Role Services dialog box, select Incoming Remote Transactions and Outgoing Remote Transactionscheckboxes. These options will be used by MSDTC. Click Next
  
  
  
  
• 　　In the Confirm Installation Selections dialog box, click Install. This will go thru the process of installing the Application Server role
  
  
  
  
• 　　In the Installation Results dialog box, click Close. This completes the installation of the Application Server role on the first node. You will have to repeat this process for the other server
  

　　We have now gone thru the process of creating the cluster at this point. In the next tip in this series, we will go thru the process of installing the Failover Cluster feature, validating the nodes that will become a part of the cluster and creating the cluster itself. And that is just on the Windows side. Once we manage to create a working Windows Server 2008 cluster, that's the only time we can proceed to install SQL Server 2008.
