• Installazione is the basic concept of getting the new operating system on your hardware. Specifically, a clean installation requires deleting the previous operating system.
• Upgrade means moving from your existing operating system to Windows Server 2012 R2, while staying on the same hardware. Even while staying on the same hardware, some server roles might require specific steps to ensure a smooth upgrade.
• Migration means moving from your existing operating system to Windows Server 2012 R2 by transferring to a different set of hardware.

Clean installation

Before you start a clean installation of Windows Server 2012 R2, you should perform the following steps.

1. Review the system requirements
2. Review preinstallation documentation
3. Obtain the product
4. Perform preinstallation tasks

Processore

Processor performance depends not only on the clock frequency of the processor but also on the number of processor cores and the size of the processor cache.

• Minimo: 1.4 Processore GHz a 64 bit

RAM

I seguenti sono i requisiti di RAM stimati per questo prodotto:

• Minimo: 512 MB (Only for installation, for using you need more)

Importante

Se si crea una macchina virtuale con i parametri hardware minimi supportati (1 core del processore e 512 MB RAM) e quindi tentare di installare questa versione sulla macchina virtuale, L'installazione fallirà.

Per evitare questo, eseguire una delle seguenti operazioni:

• Assegnare più di 800 MB RAM to the virtual machine you intend to install in this release. Once Setup has been completed, puoi modificare l'allocazione a un minimo di 512 MB RAM, a seconda della configurazione effettiva del server.
• Interrompere il processo di avvio di questa versione sulla macchina virtuale con Shift+F10. Nel prompt dei comandi che si apre, utilizzare Diskpart.exe per creare e formattare una partizione di installazione. Correre Wpeutil createpagefile /percorso=C:\pf.sys (presupponendo che la partizione di installazione creata fosse C:). Chiudere il prompt dei comandi e procedere con l'installazione.

Disk space requirements

The following are the estimated minimum disk space requirements for the system partition.

• Minimo: 32 GB (Only for installation, for using you need more)

La partizione di sistema avrà bisogno di spazio aggiuntivo per una qualsiasi delle seguenti circostanze:

• Se si installa il sistema su una rete.
• Computer con più di 16 GB di RAM richiederà più spazio su disco per il paging, ibernazione, e scaricare i file.

Altri requisiti

You also must have the following:

• Gigabit (10/100/1000baseT) Ethernet adapter
• Azionamento DVD (Se si intende installare il sistema operativo da DVD Media)

Perform preinstallation tasks

Before you install Windows Server 2012 R2, follow the steps in this section to prepare for the installation.

• Disconnect UPS devices. If you have an uninterruptible power supply (UPS) connected to your destination computer, disconnect the serial cable before running Setup. Setup automatically attempts to detect devices that are connected to serial ports, and UPS equipment can cause issues with the detection process.
• Back up your servers. Your backup should include all data and configuration information that is necessary for the computer to function. It is important to perform a backup of configuration information for servers, especially those that provide network infrastructure, such as Dynamic Host Configuration Protocol (DHCP) server. When you perform the backup, be sure to include the boot and system partitions and the system state data. Another way to back up configuration information is to create a backup set for Automated System Recovery.
• Disable your virus protection software. Virus protection software can interfere with installation. For example, it can make installation much slower by scanning every file that is copied locally to your computer.
• Provide mass storage drivers. If your manufacturer has supplied a separate driver file, save the file to a floppy disk, CD, DVD, or Universal Serial Bus (USB) flash drive in either the root directory of the media or the amd64 cartella. To provide the driver during Setup, on the disk selection page, clic Load Driver (or press F6). You can browse to locate the driver or have Setup search the media.
• Be aware that Windows Firewall is on by default. Server applications that must receive unsolicited inbound connections will fail until you create inbound firewall rules to allow them. Check with your application vendor to determine which ports and protocols are necessary for the application to run correctly.
