Why Opt for Synology NAS for VM Storage?
TL;DR Key Takeaways:
Synology NAS delivers centralized and reliable storage for VMs, boasting features such as snapshots, replication, and high availability, making it an excellent match for today’s virtualized landscapes.
NFS is generally favored over iSCSI for VM storage due to its straightforward nature, adaptability, and ease of management, particularly in shared storage environments.
Enhancing network configuration, including the deployment of dedicated VLANs and NICs, can significantly advance NFS performance and security for VM storage.
Critical setup steps involve creating shared folders, enabling NFS services, and using absolute mount paths for dependable access.
Advanced capabilities like SSD caching, cross-site replication, and snapshot protection plans significantly bolster performance, disaster recovery, and data integrity.
Setting up a Synology NAS as centralized storage using NFS (Network File System) is a pragmatic method for optimizing storage management within virtualization. This configuration boosts VM operations, supports high availability, and strengthens data protection. Synology NAS stands out as a strong, centralized storage solution designed specifically for virtualized settings. Key advantages include:
Centralized storage management: Simplifies access for numerous hosts, thereby reducing the complexity of storage operations.
Seamless VM migration: Facilitates live migration with minimal downtime, ensuring operational continuity.
High availability support: Guarantees continuous access during hardware or network disruptions.
Advanced data protection: Utilizes snapshots and replication to bolster disaster recovery strategies.
These features affirm that Synology NAS is a reliable option for contemporary virtualized infrastructures, ensuring both scalability and operational efficacy.
Comparing NFS and iSCSI for VM Storage
The choice of protocol for VM storage holds substantial importance. NFS and iSCSI are two prevalent options, each showcasing unique attributes:
NFS (Network File System): A file-based protocol that simplifies shared storage, backups, and snapshots. It is user-friendly, making it ideal for environments that require resource sharing across multiple hosts.
iSCSI (Internet Small Computer Systems Interface): A block-level protocol that has the potential for higher performance in specific cases but demands more intricate management and setup.
In the majority of virtualization scenarios, NFS is favored for its simplicity, flexibility, and compatibility with secure IP-based authentication practices like VLANs.

Preparing Your Network for NFS Storage
Adequate network preparation is crucial for achieving optimal performance and security with NFS storage. Here are best practices to consider:
Dedicated VLAN: Segment storage traffic to avert interference from other network activities, thereby boosting security.
Dedicated NICs: Designate separate network interface cards for storage traffic to reduce bottlenecks and enhance throughput.
IP-based authentication: Limit NFS access solely to authorized VM hosts, adding a necessary layer of security.
Implementing these strategies creates a stable and secure foundation for your NFS storage framework.
Steps for Configuring NFS on Synology NAS
To set up NFS on your Synology NAS for VM storage, follow these outlined steps:
Create a shared folder: Establish a folder for VM storage, allowing for checksum and compression based on your performance criteria.
Enable NFS services: Activate NFS services in the NAS control panel and configure permissions for authorized VM hosts.
Use absolute mount paths: Utilize absolute paths when connecting VM hosts to ensure dependable access to shared storage.
This configuration enables your Synology NAS to act as a dependable and efficient storage solution for virtualization.
Connecting VM Hosts to NFS Storage
After configuring your Synology NAS, connect your VM hosts to the NFS storage with the following steps:
Utilize the dedicated VLAN: Ensure storage traffic is directed through the dedicated VLAN, optimizing performance and security.
Add the NFS share: When using virtualization platforms like Xen Orchestra or XCP-ng, set the NFS share as a storage repository.
Enable advanced features: Allow multiple hosts to access the shared storage, facilitating live VM migration and high availability.
This arrangement enhances VM management and guarantees smooth operations throughout your virtualization setup.
Enhancing Performance for Virtualization Workloads
To optimize your Synology NAS’s performance in a virtualized setting, consider these enhancement strategies:
Enable SSD caching: Boost I/O operations per second (IOPS) for demanding workloads by leveraging SSD caching functionality.
Disable compression for performance-critical tasks: Avoid using compression in latency-sensitive scenarios, as it can introduce delays.
Regularly monitor storage performance: Analyze storage metrics periodically to pinpoint and rectify any potential bottlenecks.
These optimizations ensure that your storage infrastructure can effectively manage the demands of virtualization.
Improving High Availability and Disaster Recovery
NFS storage plays an integral role in facilitating high availability and enhancing disaster recovery:
Facilitate smooth migration: Transition VMs between hosts with minimal downtime, allowing maintenance or hardware upgrades without disruptions.
Leverage snapshots and replication: Implement these features to create a solid disaster recovery plan, ensuring rapid recovery from data loss or system failures.
These capabilities significantly enhance operational continuity and resilience, minimizing the likelihood of extended downtimes.
Securing Your NFS Storage Environment
Protecting your NFS storage is imperative to safeguard sensitive information. These security measures are recommended:
Isolate storage traffic: Implement a dedicated VLAN and set up switch-level VLAN tagging to enhance security.
Restrict access: Enable IP-based authentication to permit connections only from authorized hosts.
Establish firewall rules: Limit NFS traffic to designated IP ranges to prevent unauthorized access.
These strategies ensure that your storage environment remains secure and resistant to potential threats.
Leveraging Advanced Synology NAS Features
Synology NAS offers advanced functionalities to improve storage management and data protection:
Cross-site replication: Set up backups at remote sites to bolster disaster recovery efforts.
Snapshot protection plans: Quickly recover from accidental deletions or ransomware incidents, ensuring data consistency and availability.
These features empower you to maintain a strong and secure storage framework for your virtualized environment.
