What Is a Network Storage Server? NAS Explained Simply
The terms Network Attached Storage and Network Storage Server refer to the same concept: a standalone storage system with its own operating system that connects to the network via Ethernet and provides centralized data access to multiple users. Unlike a traditional file server, whose main task is to host applications, a NAS primarily handles storage and data management tasks and operates in a resource-efficient manner. Access is file-based via established protocols, and administration is handled through an intuitive web interface. This allows such a system to be set up and integrated into daily workflows even without in-depth storage expertise.
- Centralized network storage: All employees access a shared storage pool via LAN or Wi-Fi. Standard protocols such as SMB/CIFS for Windows, NFS for Linux and Unix, and AFP for macOS are supported simultaneously. User management can be organized centrally via an Active Directory connection.
-
Data security through RAID: Configurable RAID levels such as RAID 1, 5, 6, or 10 protect against the failure of individual hard drives. Hot-swappable drive bays allow defective drives to be replaced during operation. In addition, snapshots and replication provide additional layers of protection.
- Versatile use cases: A single system can function as a file server, central backup destination, virtualization storage via iSCSI, storage for video surveillance data, private cloud, or container platform, thereby consolidating services that were previously spread across multiple devices.
- Scalable from SMB to enterprise: From a compact 2-bay desktop NAS for small teams to a rackmount system with 24 or more bays and 10 GbE or 25 GbE connectivity for larger enterprises, every NAS system can be configured to meet your needs. JBOD expansions extend the lifespan of your investment by allowing storage to be added at any time.
NAS, SAN, or JBOD? A Comparison of Storage Solutions
In the storage environment, you will regularly encounter three terms that, while related, are technically distinct from one another: NAS, SAN, and JBOD. Which solution is right for your needs depends on the type of data access, the required performance, and the existing network infrastructure. The following overview compares the three concepts and helps you determine which is right for you.

While NAS servers are characterized by their straightforward integration into existing networks, SAN storage solutions from Thomas-Krenn are primarily used when particularly low latencies and high IOPS rates are required. JBOD systems are not standalone storage systems but are used exclusively to expand the capacity of existing environments. You can find an overview of all available models and manufacturers in the Thomas-Krenn storage product range.
Buying a NAS – Key Selection Criteria
Anyone looking to purchase a NAS system for their business faces a number of specific decisions regarding capacity, performance, and connectivity. The right system depends on the intended use, current data volumes, and expected growth in the coming years. If you haven’t yet clearly defined these key factors, our presales team will be happy to assist you with a free consultation on suitable NAS servers and configurations.
- Storage requirements and number of drive bays: A rule of thumb that has proven effective is to double current requirements for a planning horizon of three to five years. For small teams, 2 to 4 bays are sufficient; medium workloads run comfortably on systems with 8 to 12 bays; and starting at 16 bays, we’re talking about enterprise scenarios. A mix of HDDs for capacity and SSDs or NVMe modules as cache is worthwhile wherever frequent read and write accesses need to be accelerated.
- Expandability and scalability: Determine at the time of purchase whether the system can be expanded later via JBOD and how many additional units are supported. Hot-swappable drive bays are practically a must in an enterprise environment, as they allow for the replacement of defective drives without interrupting ongoing operations. The question of the maximum number of snapshots, volumes, and shares is also part of a thorough preliminary selection process.
- CPU and RAM: In many cases, a modern 4-core processor is sufficient for simple file sharing. However, when virtualization, databases, or large snapshots on a ZFS pool come into play, you should plan for 8 or more CPU cores and at least 32 GB of ECC RAM. For particularly memory-intensive workloads such as deduplication or large block pools, at least 64 GB of RAM is recommended.
- Network connectivity: For small teams with manageable data volumes, a standard 1-GbE connection is sufficient. As soon as more than ten users access the system simultaneously, 4K video material is regularly edited, or the NAS serves as a backup destination for large amounts of data, upgrading to 10 GbE or 25 GbE is recommended. Link aggregation allows multiple ports to be bundled into a single logical connection, thereby providing additional bandwidth and reliability.
- Protocols and Integration: SMB 3 for Windows clients and NFS v4 for Linux environments are standard today, and iSCSI is a must as soon as a NAS is used as VM storage. For cloud workloads or backup-to-object scenarios, the S3 protocol should also be supported. Additionally, ensure that integration with Active Directory or LDAP is possible so that you do not have to maintain user management in parallel.

Typical Use Cases for NAS Systems
In practice, network storage servers cover a wide range of tasks that were previously distributed across multiple specialized systems. The following four scenarios illustrate the situations in which a NAS most frequently proves its worth.
- Central File Server: Departmental shares, project data, and media files can be managed in one place, with granular access controls per folder and seamless integration with Active Directory.
- Backup destination for servers & clients: Daily backups from Veeam, Proxmox Backup Server, or Windows’ built-in tools can be reliably stored on network storage, supplemented by immutable snapshots as protection against ransomware. For more information, see the backup solutions at Thomas-Krenn.
- Storage for Virtualization: Using iSCSI or NFS datastores, a NAS provides high-performance storage for VMware, Proxmox VE, or Hyper-V, making it a cost-effective alternative to a full-fledged SAN.
- Private Cloud & File Sync: With a NAS, you can build a GDPR-compliant alternative to public cloud services, where data never leaves your data center and employees can access it from anywhere via an app or browser.

Frequently Asked Questions About Network-Attached Storage Servers
A traditional file server is essentially a general-purpose server running a standard operating system such as Windows Server or Linux, where file sharing is just one of several possible functions. Network Attached Storage (NAS), on the other hand , is a dedicated storage system whose operating system is optimized exclusively for storage provisioning and data management, making it correspondingly more performant, energy-efficient, and easier to administer. This makes a NAS suitable for businesses that need fast and straightforward storage without having to set up a full-fledged server with all the associated administrative requirements. In very specific scenarios involving custom applications or particularly complex permission structures, however, a dedicated file server may be the better choice.
For continuous use in a NAS, you should exclusively use NAS-certified hard drives, such as the WD Red Pro, Seagate IronWolf Pro, or Toshiba’s N300 and MG series. These drives are designed for 24/7 operation, vibration-optimized for use in multi-bay enclosures, and feature specially adapted firmware that works reliably with the RAID mechanisms of modern NAS systems. Additional SSDs or NVMe modules can be effectively used as read and write caches to accelerate frequently accessed data. In the systems we configure, we exclusively install drives that have been officially approved by Synology, Open-E, or the respective hardware manufacturer.
Yes, a self-hosted NAS within your company’s internal network is considered a proven GDPR-compliant alternative to public cloud services, since the data never physically leaves your company. However, this requires adherence to a few basic rules: data encryption both at rest and in transit, clearly defined access rights, regular security updates for the operating system, and a documented and tested backup strategy. The 3-2-1 backup rule has proven effective in this context, whereby three copies of the data are maintained on two different types of media, one of which is located off-site.
A NAS is a standalone storage system with its own operating system, CPU, and network stack that can be integrated directly into a corporate network and accessed by multiple users simultaneously. A JBOD (Just a Bunch of Disks), on the other hand, is simply a hard drive enclosure for storage expansion that has no built-in intelligence and solely provides additional capacity to the connected host. The connection is typically made via SAS directly to a server or an existing NAS, with the RAID controller there managing the connected drives. JBOD systems from Thomas-Krenn should therefore not be viewed as an alternative to a NAS, but rather as a useful addition once the bays of your existing system are full.
Yes, a NAS is ideal as a repository for popular backup solutions such as Veeam Backup & Replication or Proxmox Backup Server and is used for exactly that purpose in many companies. The NAS can be integrated as a backup destination via SMB or NFS; alternatively, iSCSI provides a block-based volume that behaves like a local hard drive. For Veeam environments, we recommend enabling immutable snapshots on the NAS side, as these immutable recovery points provide effective protection against ransomware by preventing subsequent encryption of the backups. Our backup specialists would be happy to discuss which configuration makes sense for your environment in a personal consultation and advise you on the appropriate backup strategy.
