Microsoft has introduced many new storage related features in Windows Server 2012 R2. This article series takes an early look at some of the new storage related features as they appear in the Windows Server 2012 Preview Release. Windows Server 2012 R2 brings a host of new features that greatly enhance the functionality of the operating system. Many of these improvements expand on existing capabilities of Windows Server 2012. In a previous slideshow. Windows Server 2003 (sometimes informally referred to as Win2K3, or just 2K3) is a server operating system produced by Microsoft and released on April 24, 2003. It was a successor of Windows 2000 Server and incorporated some. History. Microsoft introduced Windows Server 2008 R2 at the 2008 Professional Developers Conference as the server variant of Windows 7. On January 7, 2009, a beta release of Windows Server 2008 R2 was made available to. I'd like to see some information on licensing, fo instance, would you have to buy a full Windows Server 2003 Enterprise Edition license to upgrade an existing Windows 2003 Server, or is there an Upgrade license available? This download comes as a pre-configured VHD and helps you evaluate the new features of Windows Server 2003 R2, the most productive infrastructure platform for powering connected applications, networks, and Web services from. Windows Server. Windows Server is the platform for building an infrastructure of connected applications, networks, and web services, from the workgroup to the data center.

Introduction: “Special” virtual machines< /h. Not all virtual machines (VMs) in your production deployment are created equal… some are just special! Therefore, it is important for these “Utility” VMs to start up before other “Dependent” VMs in your private cloud.
Consider a VM hosting the Domain Controller for your private cloud. It is imperative for that VM to start before any VM in your private cloud that depends on Active Directory.< /p>. WS6_1. png" alt="" width="5. Virtual machine priority in Windows Server< /h.

Today in Windows Server, VM start ordering is addressed by configuring the priority of VMs. VMs can be designated a Low, Medium or High priority. This ensures that the most important VMs are started first.
Additionally, it is ensured that in the case of resource constraints, the most important VMs are running. However, there is no cross- node orchestration (by VM priority) across the nodes in a cluster. Each cluster node has an isolated view of the priority of the VMs it is hosting. Additionally, for VM start ordering based on priority, a VM is considered to be running once it reaches online state. This often does not provide a sufficient head start for its dependent VMs.< /p>.

In the past, in a world of reliable but expensive SANs, an aggressive high- availability strategy designed to fail fast was most optimal. The health of the system would be closely monitored to detect issues and react quickly and swiftly. This minimized downtime when catastrophic failures occurred.< /p>. In today’s cloud- scale environments, commonly comprising of commodity hardware, transient failures have become more common than hard failures. These transient compute and storage failures in commodity hardware are triggered by common events such as switch reset, packet loss, latency, and spanning tree convergence.
In this new world, reacting aggressively to handle transient failures can cause more downtime than it prevents.< /p>. The storage and compute stack in Windows Server 2. In a Software Defined Datacenter, we must assume infrastructure will break and it is imperative that software is resilient. At the same time, it is not acceptable to have degraded Virtual Machine (VM) availability.< /p>. Resilient private clouds: Compute and storage virtual machine resiliency< /h. Windows Server 2.
VM resiliency features to address both: < /p>. Compute failures: Due to < strong> east- west< /strong> transient < strong> network< /strong> failures.< /li>. Storage failures: Due to < strong> north- south< /strong> transient < strong> storage< /strong> failures.< /li>. WS0. 5_1. png" alt="" width="6. Compute resiliency< /h.
Transient network failures impede intra- cluster communication for your private cloud. This results in cluster nodes being removed from active membership in a cluster. In Windows Server 2. This resiliency is achieved by the following: < /p>.
A VM continues to run on a node even when it falls out of cluster membership. In this state, the node is considered to be in an “isolated” state and the VM is “unmonitored” & #8. If the network connectivity of the “isolated” node fails to recover within a certain duration, the VM is live- migrated to another node in the cluster. Note that this results in no downtime for the VM.< /li>. Additionally, “flapping” nodes, which constantly come in and out of cluster membership, are temporarily banished and placed in a “quarantined” state.< /li>.
WS0. 5_2. png" alt="" width="6. Storage resiliency< /h. A transient storage failure results in a VM being unable to access its underlying VHDX file since read or write requests to disk fail. In Windows Server 2. VM is able to seamlessly detect and be resilient to such transient failures as follows: < /p>. On detecting a transient storage failure, the tenant VM session state is preserved.< /li>. Any failure in block- or file- based storage infrastructure is handled by the VM stack, triggering an intelligent and quick response.< /li>.
The VM is moved to a “Paused. Critical” state as it waits for the storage to recover.< /li>. On recovery from the transient failure, the session state is restored.< /li>. WS0. 5_3. png" alt="" width="6. To try this new feature in Windows Server 2. Technical Preview< /a>.
