Guía de Instalación de SQL Server Denali y de AlwaysOn HADRIng. Eduardo Castro Martínezhttp://ecastrom.blogspot.comhttp://comunidadwindows.orgPara instalar SQL Server Denali, descargue los medios desde http://tinyurl.com/39ubk7rUtilice una máquina virtual que contenga Windows 2008 R2 con SP1 instalado. En caso de no tenerdisponible Windows 2008 R2, puede descargar una copia de prueba desdehttp://www.microsoft.com/downloads/en/details.aspx?FamilyID=ba571339-5436-4cf5-9c37-6ed7dab6f781&displaylang=enUna vez con la máquina instalada y con medio de SQL Server Denali, asocie el DVD del instalador con lamáquina virtual y ejecute la instalación. Se deberá desplegar la ventana inicial de instalación y seselecciona “New SQL Server and stand-alone installation”

Se ejecutan las verificaciones de instalación y puede ser que se despliegue un error en el cual se indicaque no existe una actualización de Windows que es necesaria para la instalación.

El instalador require el No-Reboot package para poder realizer la instalación, en este momento cancelela instalación y descargue e instale dicha actualización, la cual puede ser descargada desde:http://go.microsoft.com/fwlink/?LinkID=196047http://support.microsoft.com/?kbid=958488

http://go.microsoft.com/fwlink/?LinkID=196047http://support.microsoft.com/?kbid=958488

Se cancela instalación para proceder con la instalación de la actualización:

Una vez descargadas las actualizaciones se procede con la instalación de las mimas

Una vez instaladas las actualizaciones, ejecutamos nuevamente el instalador de SQL Server Denali, enesta ocasión ya no se presentan errores.

Ahora las actualizaciones ya están instaladas y las verificaciones ya son exitosas.

En la ventana de product key presionamos Next.

Se aceptan los términos y condiciones de uso.

Se procede con la instalación de los Support Tools

Una vez instalados los support Tools hacemos click en Next. Los warnings que se despliegan debido queno se han creado las reglas en el Firewall para que el SQL Server pueda ser accedido desde la red ydebido a que la máquina no tiene Internet para verificar la consistencia de los certificados de .NET.

Se debe elegir el tipo de instalación, que en nuestro caso es una instalación estándar.

En los siguientes pasos se procede a habilitar SQL Server Always On, para que esta opción esté habilitadadebe estar instalado el Windows Failover Cluster Service, para hacer siga los pasos indicados en esteartículo http://blog.augustoalvarez.com.ar/2010/12/12/five-easy-steps-to-configure-windows-server-2008-r2-failover-cluster-using-starwind-iscsi-san/ y que incluyo como un anexo al final de estedocumento.Además tiene que tener configurados dos servidores con SQL Server Denali, cada uno con una instancialocal, NO tiene que ser una instalación de Clúster de SQL Server.

Después de cambiadas esas propiedades hay que reiniciar los servicios.

Ingresamos al Management Studio

Ahora podemos crear un Nuevo Availability Group

Se especifica el nombre para el Grupo

Seleccionamos la BD que queremos incluir en AlwaysOn

Primero debemos realizer un respaldo Full de esta base de datos

Ahora la BD está disponible

Configuramos el mode de lectura de los nodos

Configuramos para que se utilice el Segundo nodo

Configuración de los endpoint y puertos

Finalizamos la configuración

Ahora AlwaysOn ya está disponible y configurado

Vemos que existentes cambios a nivel del FailOver Cluster de Windows

Podemos hacer un Failover

Con esto finalizamos las pruebas con AlwaysOn en SQL Server Denali.

Five Easy Steps to Configure Windows Server 2008 R2 Failover Cluster usingStarWind iSCSI SANhttp://blog.augustoalvarez.com.ar/2010/12/12/five-easy-steps-to-configure-windows-server-2008-r2-failover-cluster-using-starwind-iscsi-san/December 12, 2010 at 9:02 pm | Posted in Cluster, Windows Server 2008 R2 | 5 CommentsTags: Cluster, Failover Cluster, High Availability, iSCSI, StarWind, Step-by-Step, Windows Server 2008 R2When there’s a no direct requirement about the business, people usually avoid the term “cluster” intheir platform; mostly just because partial ignorance about the technology. For a long time, no matterif you were using open source platforms, Windows or any other, there was the believing that installing,configuring and maintaining a cluster is just a hard thing to do. The idea within this post is show you ina simple few steps, with no complex requirements, how to create a Windows Server 2008 R2 Failover cluster using another simple and effective solution as StarWind iSCSI SAN. StarWind iSCSI SAN software represents one of the most popular solutions available in the market to create your own iSCSI shared storage (or Storage Area Network) without the need to acquire expensive hardware solutions. StarWind iSCSI SAN provides also the fastest solution to create, configure and maintaining these type of storage, having the chance to make available LUNs to any operating system capable of using an iSCSI initiator. Let’s take a look about this step-by-step guide to create andconfigure a Windows Server 2008 R2 Failover Cluster, here are the steps involved:1. Review and complete pre-requisites for the environment.2. Install StarWind iSCSI SAN software.3. Configure and create LUNs using StarWind iSCSI SAN.4. Install Failover Cluster feature and run cluster validation.

5. Create Windows Server 2008 R2 Failover Cluster.1. Review and complete pre-requisites for the environmentRequirements for clustering in Windows Server 2008 R2 changed significantly. You don’t longer needcomplex aspects for hardware to be compatible with Failover Cluster:Requirements for Windows Server 2008 R2 Failover ClusterHere’s a review of the minimum requirements to create a Windows Server 2008 R2 Cluster: o Two or more compatible servers: You need hardware that is compatible with each other, highly recommended to always use same type of hardware when you are creating a cluster. o A shared storage: This is where we can use StarWind iSCSI SAN software. o Two network cards on each server, one public network (from which we usually access Active Directory) and a private for heartbeat between servers. This is actually an optional requirement since using one network card is possible but not suitable in almost any environment. When we are using iSCSI protocol for our shared storage Microsoft recommends three network cards on each host: Public network, private, and one dedicated to iSCSI communication from servers to the storage, which in our case will be represented by a server using StarWind iSCSI software. o Windows Server 2008 R2 Enterprise or Datacenter Editions for hosts which will be part of the cluster. Always keep in mind that cluster is not supported in Standard Editions. o All hosts must be member from an Active Directory domain. To install and configure a cluster we don’t need a Domain Admin account, but we do need a Domain account which is included in the local Administrators of each host.Requirements for StarWind iSCSI SAN SoftwareHere are the requirements for installing the component which will be in charge of receiving the iSCSIconnections: o Windows Server 2008 or Windows Server 2008 R2 o 10 GB of disk space for StarWind application data and log files o [Highly Recommended] 4 GB of RAM

o 1 Gigabit Ethernet or 10 Gigabit Ethernet.You can download StarWind iSCSI SAN software using this link, previous registration required.Optimize TCP/IP stack to improve iSCSI performanceBefore using StarWind as iSCSI target it’s recommended you’d "accelerate" TCP/IP stack to make sure itruns at full speed.1. Enable 9K Jumbo frames for your GbE network adapter.2. Change the following TCP parameters in the registry:[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters]GlobalMaxTcpWindowSize = 0×01400000 (DWORD)TcpWindowSize = 0×01400000 (DWORD)Tcp1323Opts = 3 (DWORD)SackOpts = 1 (DWORD)3. Reboot.2. Install StarWind iSCSI SAN SoftwareOk, after reviewing and completing the requirements for the environment we should start installing theStarWind iSCSI SAN software.The product is available for download in this link, and you only need a previous registration first whichwill also generate the license key you need to register the product.Installing StarWind iSCSI software is probably the easiest in all of these five steps, since you only needto complete a wizard to accomplish it.2.1 After you’ve downloaded the installation file, just double click it and the wizard will start.

2.2 Follow the wizard normally as any installation. In the process you will find one of the interestingfeatures about it: You can install the service separately from the console from which you canadminister the StarWind iSCSI.This way you can install the console on any machine compatible to access the server or servers withStarWind iSCSI and manage storage, permissions, etc. In this case, I’ll be selecting the full installation.The next steps are pretty straight forward so you won’t have any problem. Once the final steps arecompleted you’ll get a warning about the iSCSI Service needed before installing the StarWind iSCSIService.

You just need to access the “Services” console and set the service as started and automatic.After you click install, the process only takes a few seconds and you will additionally see some driversthat will be installed on the operating system; click “Install”.3. Configure and create LUNs using StarWind iSCSI SANWith the program installed, using and configuring it won’t give us any trouble.The StarWind iSCSI console is similar as any other console you may already use it. In the “General”screen we’ll find the summary information plus how to connect to local or remote StarWind host.

In the “Configuration” section we can find the common parameters to configure iSCSI StarWind, forexample the “Network” options which enable the iSCSI communications (port 3260) on any of thenetwork adapters identified.If we are using a special LAN/VLAN to separate our iSCSI traffic as recommended, then we should onlyenable the IP address used for that purpose.Now let’s get started with the StarWind configuration.

Configuring StarWind iSCSIWe are going to review the basic steps to configure the StarWind iSCSI to start hosting LUNs for ourcluster; the initial task is to add the host:3.1 Select the “Connect” option and type in the credentials to manage the iSCSI host. The defaultsused by StarWind are: User “root”; Password “starwind”.3.2 With the host added, we can start creating the storage that will be published through iSCSI: Right-click the server and select “Add target” and a new wizard will appear.3.3 Select the “Target alias” from which we’ll identify the LUN we are about to create and thenconfigure to be able to cluster. In my case I’m using a simple name “w2k8r2-clstr”, click on “Next”.3.4 Since we are going to be using hard drives to present our storage, in “Storage Type” select “HardDisk”, click on “Next”.

3.5 In “Device Type” please note that we can use physical as virtual drives to present to our clientsusing iSCSI. We are going to select “Basic Virtual”, from which we’ll create a file (.img) that willrepresent the LUN; click on “Next”.3.6 Select “Image File device” and click on “Next”.

3.7 Since we are creating a new one, select “Create new virtual disk” and click on “Next”.3.8 In the following screen, select the destination and size for the file we are creating. In my case, I’musing a separate drive where I’m going to save all of my LUNs.

3.9 In the following options leave selected “Asynchronous mode” for the LUN, which will enablemultithreaded disk operations (recommended for NTFS file system) and check “Allow multipleconcurrent iSCSI connections (clustering)” which, of course, will provide the possibility for severalhosts to be able to connect to this image file; click on “Next”.3.10 In the cache parameters, leave the default options selected “Normal (no caching)”; click on“Next”.

3.11 In the last screen, just click on “Finish” and we’ll have our LUN ready.As optional and recommended review the options for “CHAP permissions” and “Access Rights”. Withinthese options we can configure all the parameters needed for secure environments.Once we’ve completed this, we can access this file from a Windows Server 2008 R2 host.Configure Windows Server 2008 R2 iSCSI InitiatorEach host must have access to the file we’ve just created in order to be able to create our FailoverCluster. On each host, execute the following:3.12 Access “Administrative Tools”, “iSCSI Initiator”.3.13 In the “Target” pane, type in the IP address used for the target host, our iSCSI server, to receivethe connections.

In my case, I’ve created two LUNs available for the cluster.3.14 Click on “Connect” to be authorized by the host to use these files.Once we’ve connected to the files, access “Disk Management” to verify we can now use these files asstorage attached to the operating system.

3.15 And as a final step, just using the first host in the cluster, put “Online” the storage file and selectalso “Initialize Disk”. Since these are treated as normal hard disks, the process for initializing a LUN isno different than initializing a physical and local hard drive in the server.Now, let’s take a look about the Failover Cluster feature.4. Install Failover Cluster feature and run cluster validationPrior to configure the cluster, we need to enable the “Failover Cluster” feature on all hosts in thecluster and we’ll also run the verification tool provided by Microsoft to validate the consistency andcompatibility of our scenario.4.1 In “Server Manager”, access “Features” and select “Failover Cluster”. This feature does not need areboot to complete.4.2 Once installed, access the console from “Administrative Tools”. Within the console, the option weare interested in this stage is “Validate a Configuration”.

4.3 In the new wizard, we are going to add the hosts that will represent the Failover Cluster in order tovalidate the configuration. Type in the server’s FQDN names or browse for their names; click on“Next”.4.4 Select “Run all tests (recommended)” and click on “Next”.

4.5 In the following screen we can see a detailed list about all the tests that will be executed, takenote that the storage tests take some time; click on “Next”.If we’ve fulfilled the requirements reviewed earlier then the test will be completed with no warning.We can also have a detailed report about the results on each test.

5. Create Windows Server 2008 R2 Failover ClusterAt this stage, we’ve completed all the requirements and validated our configuration successfully. Inthe next following steps, we are going to see the simple procedure to configure our Windows Server2008 R2 Failover Cluster.5.1 In the “Failover Cluster” console, select the option for “Create a cluster”.5.2 A similar wizard will appear as in the validation tool. The first thing to do is add the servers wewould like to cluster; click on “Next”.5.3 In the next screen we have to select the cluster name and the IP address assigned. Remember thatin a cluster, all machines are represented by one name and one IP.

5.4 In the summary page click on “Next”.After a few seconds the cluster will be created and we can also review the report for the process.Now in our Failover Cluster console, we’ll get the complete picture about the cluster we’ve created:Nodes involved, storage associated to the cluster, networks and the events related to cluster.

We will close up our step-by-step guide here and open the clustering series for maybe a detailedexplanation about type of Failover Clusters, including Multi-Site cluster which I had the chance topresent on a Microsoft event here in Buenos Aires.ConclusionsAfter reviewing the process to create clusters using StarWind iSCSI SAN software, here are some of thethings I’ve noticed:Pros o StarWind iSCSI software is a simple tool to install and simpler to use and administer shared storage; not only for using it in a Failover Cluster, but for all scenarios when we need shared storage. o If we have the proper environment for iSCSI, StarWind iSCSI can save us a lot of money comparing the costs of an enterprise hardware solution to use iSCSI. o The tool provides also important differences with other similar in the market, for example, granularity of permissions we can achieve to guarantee a secure environment.Cons o Setting up the right environment for iSCSI using StarWind can represent a complex situation. There is no golden rule, this “right environment” depends on a proper sizing and planning about the scenario and the services we’ll be providing; but for scalable and powerful solution you would

probably need SAS hard drives, 10gb network cards, possible NIC teaming and other configurations. Even though we are discussing this as a negative aspect, still is common sense to think about this complex scenario as a trade-off for an expensive hardware solution.o The price seems very accessible for most companies, but StarWind removed the free version of this tool. I hope they can bring it back any time soon; fits perfectly when we want to make our own simple labs, or like in my case that I’ve used several times in presentations :)More ResourcesHere are more resources to look into for Windows Server 2008 R2 Failover Cluster and StarWind iSCSISoftware:o Understanding Requirements for Failover Clusters: http://technet.microsoft.com/en- us/library/cc771404.aspxo iSCSI Cluster Support: Frequently Asked Questions: http://www.microsoft.com/WindowsServer2003/technologies/storage/iscsi/iscsicluster.mspxo Creating a Cluster in Windows Server 2008: http://blogs.msdn.com/b/clustering/archive/2008/01/18/7151154.aspxo StarWind iSCSI SAN: Quick Start Guide: http://www.starwindsoftware.com/starwind-iscsi-san- quick-start-guideo StarWind SAN Sizing Guide: http://www.starwindsoftware.com/san-sizing-guideo StarWind iSCSI SAN Software Manuals: http://www.starwindsoftware.com/technical-paperso StarWind iSCSI SAN Software White Papers: http://www.starwindsoftware.com/white-paperso iSCSI SAN Storage Videos and Webcasts: http://www.starwindsoftware.com/videoso Windows Server 2008 Failover Clusters: Networking (Part 1): http://blogs.technet.com/b/askcore/archive/2010/02/12/windows-server-2008-failover-clusters- networking-part-1.aspxo Simple Clustering with Hyper-V: http://technet.microsoft.com/en- us/magazine/2009.04.geekofalltrades.aspx?pr=blog
