 |Network Software|Supported operating systems for [!INCLUDE[ssCurrent](../../includes/ssnoversion-md.md)] have built-in network software. Named and default instances of a stand-alone installation support the following network protocols: Shared memory, Named Pipes, TCP/IP, and VIA.<br/><br/> **Note:** VIA protocol is not supported on failover clusters. Clients or applications running on the same node of the failover cluster as the SQL Server instance, can use Shared Memory protocol to connect to SQL Server using its local pipe address. However this type of connection is not cluster-aware and will fail after an instance failover. It is therefore not recommended and should only be used in very specific scenarios.<br/><br/> **Important:** The VIA protocol is deprecated. [!INCLUDE[ssNoteDepFutureAvoid](../../includes/ssnotedepfutureavoid-md.md)]<br/><br/> For more information about Network Protocols and Network Libraries, see [Network Protocols and Network Libraries](../../sql-server/install/network-protocols-and-network-libraries.md).|  
 |Hard Disk|[!INCLUDE[ssCurrent](../../includes/ssnoversion-md.md)] requires a minimum of 6 GB of available hard-disk space.<br/><br/> Disk space requirements will vary with the [!INCLUDE[ssCurrent](../../includes/ssnoversion-md.md)] components you install. For more information, see [Hard Disk Space Requirements](../../sql-server/install/hardware-and-software-requirements-for-installing-sql-server.md#HardDiskSpace) later in this article. For information on supported storage types for data files, see [Storage Types for Data Files](../../sql-server/install/hardware-and-software-requirements-for-installing-sql-server.md#StorageTypes).|  
 |Drive|A DVD drive, as appropriate, is required for installation from disc.|
