# Setting up the FSx for ONTAP file system
The Amazon FSx for NetApp ONTAP documentation contains instructions for setting up a file share by using the [Quick create](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/getting-started-step1.html) or [Standard create](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/creating-file-systems.html) options in the AWS Management Console. This guide includes additional recommendations and guidance for enterprises that need to support HPC workloads and Active Directory integration.
For instructions on creating an FSx for ONTAP file system in the AWS Management Console, see [Creating FSx for ONTAP file systems](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/creating-file-systems.html). For each section, note the following setup recommendations and considerations for enterprise environments.
## File system details section
1. For **Deployment type**, choose one of the following:
+ Choose **Multi-AZ** for production workloads. This option helps maintain data availability in the event that an Availability Zone is inaccessible.
+ Choose **Single-AZ** for disaster recovery purposes, for non-production workloads, or for workloads that have replication already built into the application layer and do not require additional storage-level redundancy. This option is cost-effective for these types of workloads.
For more information and recommendations about configuring the deployment type, see [Best practices for choosing an Availability Zone deployment option](best-practices.md#bp-availability-zone) in the *Best practices* section of this guide.
1. For **Provisioned SSD IOPS**, choose one of the following:
+ Choose **Automatic** if you want Amazon FSx to automatically provision 3 IOPS per GiB of SSD storage, up to up to a maximum of 160,000 SSD IOPS per file system.
+ Choose **User-provisioned mode** if you want to specify the number of IOPS. If you provision a higher level of IOPS, you pay for the average IOPS provisioned above your included rate for the month, measured in IOPS-months.
For more information, see [Storage capacity and IOPS](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/storage-capacity-and-IOPS.html), [Considerations when updating storage and IOPS](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/increase-primary-storage.html#scaling-considerations), and [Impact of storage capacity on performance](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/performance.html#impact-throughput-cap-performance) in the FSx for ONTAP documentation.
## Default storage virtual machine configuration section
1. For **Root volume security style**, choose one of the following:
+ Choose **Unix** if you plan to access the file system mainly from Linux-based clients (NFS protocol).
+ Choose **NTFS** if you plan to access the file system mainly from Windows-based clients (SMB protocol)
+ Choose **Mixed** if you plan to access the file system equally from Linux-based and Windows-based clients. This is an advanced setting.
For more information about these settings, see [What the security styles and their effects are](https://docs.netapp.com/us-en/ontap/nfs-admin/security-styles-their-effects-concept.html) (NetApp documentation).
1. For **Active Directory**, choose **Join an Active Directory**.
1. For **NetBIOS name**, enter the NetBIOS name of the Active Directory computer object that will be created for your SVM. This is often the same as the SVM name but can be different. The NetBIOS name cannot exceed 15 characters.
1. For **Active Directory domain name**, enter the fully qualified domain name of your Active Directory. The domain name cannot exceed 255 characters.
1. For **DNS server IP addresses**, enter the IPv4 addresses of the DNS servers for your domain. You can enter up to three IP addresses.
1. For **Service account username **and** Service account password**, enter the username and password of the service account in your existing Active Directory. This is the service account that you previously set up in [Provisioning an Active Directory service account](provision-service-account.md) in this guide.
1. For **Organization Unit (OU)**, enter the distinguished path name of the organizational unit to which you want to join your file system.
1. For **Delegated file system administrators group**, enter name of the group in your Active Directory that can administer your file system. The default group is `Domain Admins`.
## Default volume configuration section
1. For **Volume name**, enter a name for the volume. The name cannot exceed 203 characters, and alphanumeric and underscore (\_) characters are accepted.
1. For **Junction path**, enter the location within the file system where you want to mount the volume. The name must have a leading forward slash, such as `/vol1`. For more information, see the [Amazon FSx resources](architecture.md#fsx-resources) section of this guide.
1. For **Volume size**, enter the storage capacity of your volume, in mebibyte (MiB). Enter any whole number in the range of 20–104857600 (100 TiB).
1. For **Storage efficiency**, choose whether to enable storage efficiency features, such as deduplication, compression, and compaction. For more information, see [Storage efficiency](https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/storage-efficiency.html) in the FSx for ONTAP documentation. If these efficiency features are compatible with your HPC workload, we recommend them in enterprise environments.
1. For **Capacity pool tiering policy**, choose a tiering policy for the volume. For more information and recommendations about tiering policies, see [Best practices for storage tiers and tiering policies](best-practices.md#bp-storage-tiering) in the *Best practices* section of this guide.
