Amazon FSx for Windows File Server now supports file systems that span multiple Availability Zones

Posted on: Nov 20, 2019

You can now create Amazon FSx for Windows File Server file systems that span AWS Availability Zones (AZs), making it easy to deploy Windows file storage in AWS with high availability and redundancy across multiple AZs. Multi-AZ file systems are designed to provide continuous availability to data, even in the event that an AZ is unavailable—supporting business-critical workloads such as business applications, web serving environments, and Microsoft SQL Server.

Starting today, with a few clicks in the AWS Management Console, you can create a shared file system for your Windows applications that’s highly available and durable across AZs. With Multi-AZ file systems, Amazon FSx automatically provisions and maintains an active file server and a standby file server in separate AZs, each with its own storage. Any changes written to disk on your file system’s primary file server are synchronously replicated across AZs to the standby. During planned maintenance, or in the event of unavailability of the active file server or its AZ, Amazon FSx automatically fails over to the standby so you can resume file system operations without a loss of availability to your data.

Multi-AZ file systems are available today in the following AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland), EU (London), Asia Pacific (Tokyo), Asia Pacific (Singapore), and EU (Stockholm).
