Veeam RMAN plugin Windows network tuning

 

In larger environments lots of connections are made by the Plug-In backups. It is recommended to tune the network settings of the involved Windows machines in the Veeam infrastructure (Windows VBR server and Windows repository servers) according to the Microsoft guide to improve network performance:

• Increase the available dynamic port range. The default dynamic ports range in Windows is 49152-65535 which is 16384 ports. Use the following command to increase the amount of available dynamic ports for IPv4 to 55525 without affecting ports of Veeam services:

  netsh int ipv4 set dynamicport tcp start=10010 num=55525

• Add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpTimedWaitDelay and set it to 30 to reduce the time a port keeps being blocked for reuse (default is 240 seconds)

Alterar MTU windows server

 

Passos detalhados:

1. 1. Abra o Prompt de Comando como administrador:

   • Pressione a tecla Windows, digite "cmd" e clique com o botão direito em "Prompt de Comando", selecionando "Executar como administrador".
2. 2. Descubra o índice da interface:

   • Execute o comando: netsh interface ipv4 show interface (ou netsh interface ipv6 show interface para IPv6).
   • Este comando mostrará uma lista das interfaces de rede e seus índices (Idx). Anote o índice da interface que você deseja modificar.
3. 3. Defina o valor da MTU:

   • Execute o seguinte comando, substituindo <índice> pelo número obtido no passo anterior:
     • netsh interface ipv4 set interface <índice> mtu=9000 (para IPv4).
     • netsh interface ipv6 set interface <índice> mtu=9000 (para IPv6).
4. 4. Verifique a configuração:

   • Execute novamente o comando netsh interface ipv4 show interface (ou netsh interface ipv6 show interface) para confirmar que o MTU foi alterado para 9000.

Exemplo:

Se o índice da sua interface IPv4 for 4, o comando seria:

netsh interface ipv4 set interface 4 mtu=9000
