 # Accelerated Networking with Azure virtual machine disaster recovery

 Accelerated Networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization, for use with the most demanding network workloads on supported VM types. The following picture shows communication between two VMs with and without accelerated networking:

 This article describes how to replicate, fail over, and fail back Azure virtual machines (VMs) running in a proximity placement group to a secondary region.
 
 [Proximity placement groups](../virtual-machines/windows/proximity-placement-groups-portal.md) are a logical grouping capability in Azure Virtual Machines. You can use them to decrease the inter-VM network latency associated with your applications.

 # Remove SMB 1 on Linux
+
+> [!CAUTION]
+> This article references CentOS, a Linux distribution that is nearing End Of Life (EOL) status. Please consider your use and planning accordingly.
 Many organizations and internet service providers (ISPs) block the port that SMB uses to communicate, port 445. This practice originates from security guidance about legacy and deprecated versions of the SMB protocol. Although SMB 3.x is an internet-safe protocol, older versions of SMB, especially SMB 1, aren't. SMB 1, also known as CIFS (Common Internet File System), is included with many Linux distributions. 
 
 SMB 1 is an outdated, inefficient, and insecure protocol. The good news is that Azure Files doesn't support SMB 1. Also, starting with Linux kernel version 4.18, Linux makes it possible to disable SMB 1. We always [strongly recommend](https://aka.ms/stopusingsmb1) disabling the SMB 1 on your Linux clients before using SMB file shares in production.

 # Mount SMB Azure file share on Linux
+
+> [!CAUTION]
+> This article references CentOS, a Linux distribution that is nearing End Of Life (EOL) status. Please consider your use and planning accordingly.
 [Azure Files](storage-files-introduction.md) is Microsoft's easy to use cloud file system. Azure file shares can be mounted in Linux distributions using the [SMB kernel client](https://wiki.samba.org/index.php/LinuxCIFS).
 
 The recommended way to mount an Azure file share on Linux is using SMB 3.1.1. By default, Azure Files requires encryption in transit, which is supported by SMB 3.0+. Azure Files also supports SMB 2.1, which doesn't support encryption in transit, but you can't mount Azure file shares with SMB 2.1 from another Azure region or on-premises for security reasons. Unless your application specifically requires SMB 2.1, use SMB 3.1.1.
