1. Nano Server

Without a doubt the biggest change in Windows server is the new Nano Server. Nano Server is a pared down headless version of Windows Server. Nano Server will have a 93% smaller VHD size, 92% fewer critical bulletins and 80% fewer required reboots. Nano Server is a Windows Server installation options and it’s completely headless – there’s no GUI and no command prompt. Nano Server is designed to run Hyper-V, Hyper-V cluster, and Scale-Out File Servers (SOFSs) and cloud service applications. You can find out more about Nano Server at What You Need to Know about Microsoft Nano Server.

2. Windows Server Containers and Hyper-V Containers

The next biggest change in Windows Server 2016 will be support for containers. Containers are the latest buzz in IT technology as they threaten to supplant virtualization as a core IT technology. Containers enable you to isolate your applications from the underlying OS improving the deployment and reliability of those applications. Windows Server 2016 will provide two kinds of native containers: Windows Server Containers and Hyper-V Containers.  Windows Server Containers are isolated from each other but they run directly on the Windows Server 2016 OS. Hyper-V Containers provide enhanced isolation by running the containers from a Hyper-V VM. The current preview release doesn’t support containers yet.3. Docker Support
WS2016 F3.jpgDocker is an open-source engine that’s used for building, running and managing containers. Docker containers were originally built for Linux but the next version of Windows Server will provide built-in support for the Docker engine as well. A new open-source Docker engine project has been built for Windows Server with Microsoft participating as an active open source community member. You can use Docker to manage Windows Server and Hyper-V Containers
  • 4. Rolling upgrades for Hyper-V and Storage clusters

    WS2016 F4.jpg

    One of the biggest new changes for Hyper-V in Windows Server 2016 is rolling upgrades for Hyper-V clusters. The new rolling upgrades feature allows you to add a new Windows Server 2016 node to a Hyper-V cluster with nodes that are running Windows Server 2012 R2. The cluster will continue to run at the Windows Server 2012 R2 functional level until all of the cluster nodes have been upgraded to Windows Server 2016. When the cluster has mixed level nodes the management must be done from Windows Server 2016 or Windows 10. New VMs on a mixed cluster will be compatible with the Windows Server 2012 R2 feature set.

  • 5. Hot add & remove of virtual memory network adapter

    WS2016 F15.jpg
    Another great new feature in Windows Server 2016 Hyper-V is the ability to add and remove virtual memory and virtual network adapters while the virtual machine is running. In previous releases you need to use dynamic memory to change the minimum and maximum RAM settings of a VM that is running. Windows Server 2016 enables you to change the allocated RAM while the VM is active even if the VM is using static memory. Likewise, you add and remove network adapters while VM is running.

  • 6. Nested virtualization
    WS2016 F6.jpg

    Added primarily for the new container support, Windows Server 2016’s nested virtualization capabilities will also be a handy addition for training and lab scenarios. With this new feature you are no longer limited to running the Hyper-V role on a physical server. Nested virtualization enables you to run Hyper-V within a Hyper-V virtual machine.

  • 7. PowerShell Direct
    WS2016 F7.jpg

    PowerShell is a great management automation tool but it can be complicated to get it to run remotely against your VMs. You need to worry about security policies, firewall configurations and your host networking configuration. PowerShell Direct enables you to run PowerShell commands in the guest OS of a VM without needing to go through the network layers. Like VMConnect (the remote console support provided by the Hyper-V Manager) it requires zero configuration it connects directly to the guest VM and all you need are authentication credentials for the VM’s guest OS. You can learn more about PowerShell Direct at the Virtualization Blog.

  • 8. Linux Secure Boot
    WS2016 F8.jpg

    Another new feature in Windows Server 2016 Hyper-V is the ability to enable secure boot for VMs with Linux guest operating systems. Secure Boot is a feature of the UEFI firmware specification incorporated in Generation 2 VMs that protects the VM’s hardware kernel mode code from being attacked by root kits and other boot-time malware. Previously, Generation 2 VMs supported Secure Boot for Windows 8/8.1 and Windows Server 2012 VMs but not VM’s running Linux.

  • 9. New Host Guardian Service and Shielded VMs
    WS2016 F9.jpg

    The Host Guardian Service is a new role in Windows Server 2016 that enables shielded virtual machines and protects the data on them from unauthorized access – even from Hyper-V administrators. Shielded VMs can be created using the Azure Management Pack Portal. Standard VMs can also be converted to Shielded VMs. With Shielded VMs Hyper-V virtual disks can be encrypted with BitLocker. For more information check out Shielded Virtual Machines in Windows Server.

  • 10. Storage Spaces Direct

    WS2016 F10.jpg

    Windows Server 2016 also has a number of storage system improvements one of the most important is the new Storage Spaces Direct feature. Storage Spaces Direct is the evolution of the previous Storage Spaces technology found in Windows Server 2012 R2. Windows Server 2016 Storage Spaces Direct allows a cluster to access JBOD storage in an external enclosure like Windows Server 2012 R2 or it can also allow access to JBOD and SAS disks that are internal to the cluster nodes. Like the previous release Store Spaces form the basis for Storage Pools and they support both SSD and HDD disks and data tiering. You can learn more about Store Spaces direct from John Savill’s article What is Storage Spaces Direct?

ambiente com Hyper-v Replica, a VM pausa a réplica em entra em “Error State”
visualizando o Event Viewer do host, você encontra o event ID: 32022 com o descritivo:
Hyper-v could not replica changes for virtual machine “VM01”: The device does not recognize the commendo (0x80070016)

Aplicado hotfix nos hosts do Secondary Site:https://support.microsoft.com/en-us/kb/3012714

sugiro a leitura do KB “Event IDs 19050, 32022, 32032, 32056, 32315, 32546 and 33680 are logged when Hyper-V replication is in progress”

“Configuration Error” for Network Adapter property when you use Failover Clustering July 3, 2014

Posted by Samuel RIbeiro in Windows 2012.
add a comment

Uma dica rápida pra não perder tempo revalidando todos os VS, configurações de rede ETC no Windows 2012
esse problema ocorre somente quando você faz Live Migration e Quick MIgration com a VM desligada
no meu caso, tenho várias VMs desligadas porque são replicas🙂

Solução: You can safely ignore this error. When the virtual machine is brought online, the adapter property is updated, and this clears the error.

Pessoal,

mais um post da série sobre pré-requisito e limitações de features que geralmente você só descobre que os itens não funcionam ou não são suportados quando já está na implementação e ai se você não tiver feito a lição de casa de ler as documentações
o resultado é o retrabalho🙂

Abaixo uma tabela com informações sobre usar o tradicional Cluster de File Server ou um Scale-Out File Server
no Exemplo, SOFS não é um bom negócio com DFS por exemplo
confira a documentação na integra:
You should not use Scale-Out File Server if your workload generates a high number of metadata operations, such as opening files, closing files, creating new files, or renaming existing files. A typical information worker would generate a lot of metadata operations. You should use a Scale-Out File Server if you are interested in the scalability and simplicity that it offers and if you only require technologies that are supported with Scale-Out File Server.

Máquina Virtual entra em Save State durante Backup May 5, 2014

Pessoal,

Abaixo segue um check-list que usei para fazer o troubleshooting e resolver os problemas Máquina Virtual que entra em Save State durante o backup
Estou considerando neste post, que o problema ocorra apenas com algumas máquinas  virtuais e o host de Hyper-v esteja em ordem
além de todas as atualizações e hotfixes para Hyper-v e Cluster estarem instalados

Nesse link, você pode consultar todos os estados de uma máquina Virtual, como por exemplo a diferença entre o Save State e Pause
Managing virtual machine state

1. The VM guest needs to have Integration Services installed, enabled, and running
2. All disks involved need to be formatted with NTFS, including the disks within the VM.
3. Ensure the VMs are partitioned using ‘basic disk’ formatting. At the moment Hyper-V does not support live backup for VMs formatted using dynamic disk partitioning or GPT.
4. Windows Update with latest Updates
5. Ensure you have at least about 20% free space on each drive involved, such as the drive on the host and the VM’s main system drive.
6. (COM System Application Service, Distributed Transaction Coordinator Service, and Volume Shadow Copy Service). Also review the VM settings in Hyper-V, the ‘backup’ option needs to be checked.
7. The Volume Shadow Copy Service and related VSS services need to be enabled and running.
8. The shadow copy storage space for each drive must be available to Hyper-V VSS Writer and be located at the same volume. For instance, the storage space for drive C: needs to be on drive C: itself, and so on. Use the VSSADMIN command from the command line to check the settings. (Use: vssadmin list shadowstorage / vssadmin resize shadowstorage)

Espero que ajude

Pessoal,
Segue um link interessante sobre as configurações, pré-requisitos e limitações do Storage spaces no Windows 2012 e Windows 2012R2

  1. Você sabia que Storage Spaces com controladores ISCSI e Fibre Channel não é suportado?
  2. Para ser utilizado Storage Space em Failover Cluster, é necessário ao menos três discos fisicos e um hotspare?
  3. É necessário desativar o seu RAID para utilizar o recurso
  4. A opção de disco com paridade é suportada apenas no Windows 2012R2

Todas essas respostas você encontra no links a seguir

Evento 50 – O W32Time registra com freqüência no Event Viewer April 27, 2014

Posted by Samuel RIbeiro in Uncategorized.
add a comment

Já tive em várias ocasiões esse log, mesmo com a hierarquia de NTP estar funcionando normalmente
Segue uma dica rápida que utilizo para elimiar esse evento
a grande questão desse erro é que você precisa repetir isso algumas vezes até que fique 100%
porque em todos os meus casos, só executar o commando uma vez, não resolveu.

Execute o commando no prompt de commando como Administrador
w32tm /resync
Net stop w32time
Net start w32time
para consultar qual o servidor de horário atual da estação\servidor em que você está logado, utilize o commando abaixo
w32tm /query /status

Para o Windows Server 2012 Hyper-V e Windows Server 2012 R2 Hyper-V, o arquivo de paginação do sistema operacional (normalmente chamado de sistema operacional host) gerenciamento deve ser deixado no padrão de configuração de “Sistema gerenciado”. Isso é pelo grupo de produto Hyper-V.
se alguma necessidade especifica é requerida
