Amazon FSx for Windows File Server provides fully managed, highly reliable file storage that is accessible over the Server Message Block (SMB) protocol. It is built on Windows Server, delivering a wide range of administrative features such as user quotas, end-user file restore, and Microsoft Active Directory integration, consistent with operating an on-premises Microsoft Windows file server. Today, we are happy to announce two new features: storage capacity scaling and throughput capacity scaling. The storage capacity scaling allows you to increase your file system size as your data set increases, and throughput capacity is bidirectional letting you adjust throughput up or down dynamically to help fine-tune performance and reduce costs. With the capability to grow storage capacity, you can adjust your storage size as your data sets grow, so you don’t need to worry about growing data sets when creating the file system. With the capability to change throughput capacity, you can dynamically adjust throughput capacity for cyclical workloads or for one-time bursts to achieve a time-sensitive goal such as data migration.

When we create a file system, we specify Storage Capacity and Throughput Capacity.

The storage capacity of SSD can be specified between 32 GiB and 65,536 GiB, and the capacity of HDD can be specified between 2,000 GiB and 65,536 GiB. With throughput capacity, every Amazon FSx file system has a throughput capacity that you configure when the file system is created. The throughput capacity determines the speed at which the file server hosting your file system can serve file data to clients accessing it. Higher levels of throughput capacity also come with more memory for caching data on the file server and support higher levels of IOPS.

With this release, you can scale up storage capacity and can scale up / down throughput capacity on your file system with the click of a button within the AWS Management Console, or you can use the AWS Software Development Kit (SDK) or Command Line Interface (CLI) tools. The file system is available online while scaling is in progress and you’ll have full access to it for storage scaling. During scaling throughput, Amazon FSx for Windows switches out the file servers on your file system, so you’ll see an automatic failover and failback on multi-AZ file systems.

So, let’s have a little trip through the new feature. We’ll look at the AWS Management Console at first.
