NAS Synology SA SA6400 Rack (2U) DDR4 32 GB 2.9 GHz

The Synology SA6400 is a 12-bay enterprise storage server designed for scalable on-premises data storage. It supports expansion up to 108 drives with additional 12-bay RX1223RP units, making it suitable for enterprise data centers, large production studios, and businesses in retail or hospitality that require high-capacity, reliable storage for data-intensive projects.

Advantages

The SA6400 delivers high availability through redundant power supplies, out-of-band management for remote control and log access, and the option to form a failover cluster with Synology High Availability. It provides built-in fast connectivity with two 10GbE RJ-45 ports and supports configurable networking modules (10GbE, 25GbE, or Fibre Channel) as well as link aggregation for failover and load balancing. The system serves as a flexible platform for file sharing, private cloud services, centralized backups, VM and bare-metal protection, and hosting business applications and containers.

Key specifications

• Drive bays: 12 native, expandable up to 108 with RX1223RP units
• Default network: two 10GbE RJ-45 ports
• Expandable networking: up to 2 extra slots for 10GbE SFP+/RJ-45, 25GbE SFP28, or Fibre Channel
• Redundancy: redundant power supply support and failover cluster capability
• Management: dedicated out-of-band (OOB) management console; Central Management System and Active Insight support
• Backup and recovery: Active Backup for Business, Hyper Backup, Snapshot Replication with RPO as low as 5 minutes
• Use cases: file server, private cloud, centralized backup target, application and VM hosting, cross-site syncing

How to use

Install the SA6400 in a standard rack and connect it to your data network using the onboard 10GbE ports. Add RX1223RP expansion units as storage requirements grow to increase capacity up to 108 drives. Configure redundant power supplies and link aggregation for network resilience. Use the out-of-band management console to perform remote power control and to access system logs when the primary network is unavailable. Deploy Synology DSM services such as Synology Drive for file sharing and sync, Active Backup for Business for bare-metal and VM backups, Hyper Backup and Snapshot Replication for scheduled and point-in-time recovery, and Virtual Machine Manager or Docker for application testing and hosting.

Recommendations

For production environments, enable redundant power supplies and configure Synology High Availability between two SA6400 units to minimize downtime and data loss. Regularly schedule backups and snapshot replication, and plan capacity growth by adding RX1223RP expansion units before reaching maximum utilization.
