FAQ

1. What is network-attached storage(NAS)? What is network-attached storage used for? And who it's for?

Network-attached storage (NAS) is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection.

NAS devices typically don't have a keyboard or display and are configured and managed with a browser-based utility. Each NAS resides on the LAN as an independent network node, defined by its own unique IP address.

The purpose of network-attached storage is to enable users to collaborate and share data more effectively. It is useful to distributed teams that need remote access or work in different time zones. NAS connects to a wireless router, making it easy for distributed workers to access files from any desktop or mobile device with a network connection. Organizations commonly deploy a NAS environment as a storage filer or the foundation for a personal or private cloud.

2. What are NAS components and how do they work?

1. NAS Hardware

This refers to a combination of a NAS box, NAS unit, NAS server, or NAS head(which is essentially just a server with storage disks or drives), CPUs, and RAM. These are fundamental hardware system that comprise the NAS hardware framework.

1. NAS Software

Storage software is deployed in NAS hardware system's specialised hardware. The NAS software runs on a ligh-weight operating system.

1. NAS Protocol

There are data transfer protocols for sending and receiving data, which are accessed via switches. The most basic data transmission protocols are Internet Protocol(IP) and Send Control Protocol(TCP), which are used by the majority of clients/users to transfer data. Network File Systems(NFS) and Server Message Blocks(SMB) are the file formats used in the protocols.

3. How does NAS transfer data?

Network Attached Storage (NAS) transfers data over a network using standard network protocols. The most common protocols for NAS data transfer are:

1. Server Message Block (SMB):
• SMB is a widely used file sharing protocol. It is the standard protocol for Windows-based systems and is supported by many NAS devices. SMB allows for seamless file sharing and access across Windows, macOS, and Linux platforms.
2. Network File System (NFS):
• NFS is a protocol commonly used in UNIX and Linux environments. It enables file sharing between networked systems and is often used for NAS solutions in Linux-based environments. NFS provides a straightforward way to access and share files over a network.
3. File Transfer Protocol (FTP):
• FTP is a standard network protocol used to transfer files from one host to another over a TCP-based network. While not as commonly used for day-to-day file access, some NAS devices support FTP for file transfer.
4. Secure File Transfer Protocols:
• Protocols like Secure Copy Protocol (SCP) and Secure File Transfer Protocol (SFTP) add a layer of security to file transfers by using encryption. These protocols are often employed for secure data transfer over the network.
5. WebDAV Protocols:
• Some NAS devices provide web-based interfaces that allow users to access and transfer files through a web browser. These interfaces often use HTTP or HTTPS protocols.
6. Rsync (Remote Sync):
• Rsync is a utility and protocol used for efficiently copying and synchronizing files between devices. It is commonly employed for backup and synchronization tasks on NAS devices.

The choice of protocol depends on factors such as the type of devices accessing the NAS, the operating systems in use, and the specific use case requirements. NAS devices typically support multiple protocols, ensuring compatibility with a variety of systems and applications within a network.

4. What are NAS use cases and examples?

1. File Sharing:
• Example: Storing and sharing documents, images, videos, and other files within a local network.
2. Backup and Recovery:
• Example: Scheduled backups of critical data from multiple devices for data protection and easy recovery.
3. Media Server:
• Example: Storing and streaming media files (music, videos, photos) to various devices such as smart TVs, gaming consoles, and media players.
4. Data Synchronization:
• Example: Keeping files and folders synchronized across multiple devices for seamless access and collaboration.
5. Remote Access:
• Example: Accessing files stored on NAS remotely over the internet, providing a secure and convenient way to retrieve data.
6. Surveillance Storage:
• Example: Storing and managing surveillance footage from IP cameras for security and monitoring purposes.
7. Personal Cloud Storage:
• Example: Creating a private cloud environment for personal use, allowing users to access and sync files from anywhere.
8. Virtualization Storage:
• Example: Providing shared storage for virtual machines in a virtualized environment for better resource utilization.
9. Home Automation:
• Example: Storing data for home automation systems, such as smart home configurations and logs.
10. Collaboration and File Versioning:
• Example: Facilitating collaborative work by allowing multiple users to access and edit files while maintaining version control.
11. Data Archiving:
• Example: Archiving older or less frequently used data to free up primary storage space on other devices.
12. Web Server:
• Example: Hosting a website or web application by storing web content and serving it over the network.
13. Educational Institutions:
• Example: Providing a centralized storage solution for educational resources, documents, and collaboration among students and staff.
14. Small Business Applications:
• Example: Supporting small business needs, such as shared document storage, backups, and collaborative workspaces.

NAS devices come in various sizes and configurations, making them suitable for both home and business environments with different storage requirements.

5. What are top considerations for choosing NAS?

• Number of Bays:
• The number of bays affects both the capacity and the data security of your NAS device. More drive bays mean more storage space for your users, and more options for data redundancy. Consider the number of bays you need based on the number of hard drives you want to use.
• Network:
• Network connectivity is an essential factor for choosing a NAS device. Most NAS devices have 1GbE connectivity, which offers fast and reliable data transfer. However, some NAS models also have dual 1GbE ports, providing connection redundancy and link aggregation. Additionally, some NAS models can be upgraded to 2.5GbE or 10GbE, which are even faster networking standards. This may be a key feature if you intend to upgrade your core network.
• Hardware:
• The hardware determines how fast and reliable your NAS device will be. CPU and RAM capacity are key factors that affect NAS performance. If you need to deploy resource-intensive applications such as virtual machines or use large RAID arrays, you should look for a NAS device with powerful hardware to handle your tasks.
• Software:
• Different NAS software may have different features and functionality. Each NAS brand comes with its own software that lets you access your files, set up your network, and perform other tasks like backup, virtual machine, or other services. You should check out the features that the software offers and see if they match your needs.

6. How to set up a NAS to securely share files?

Setting up a NAS device to securely share files can be done in a few steps, such as:

• Implementing strong password security for your NAS device and user accounts.
• Ensuring routine firmware updates: Keep your NAS device firmware routinely updated to fix any security vulnerabilities.
• Disabling the default admin account: Create a new admin account with a different username to enhance security.
• Enabling two-factor authentication: Add an extra layer of security by enabling two-factor authentication for your NAS device and user accounts.
• Using HTTPS for encryption: Ensure secure data transfer by using HTTPS to encrypt communication between your NAS device and your network.
• Setting up a firewall: Block unauthorized access to your NAS device and ports by configuring a firewall.
