All the space you will ever need
With 60 bays in a 4U rackmount enclosure and support for up to 300 drives after expansion, the Synology HD6500 is the ideal high-density storage solution for large-scale warm and cold storage applications such as full system backups, video post-production, and large surveillance deployments.

Consistent performance at five times the size
The HD6500 is designed to scale up to 5 times in capacity with four additional RX6022sas expansion units. SAS multipath-enabled connectivity provides up to double the typical performance together and increased redundancy.

Built for high reliability
The HD6500 is built to keep mission-critical data and services accessible, so that businesses can continue to perform even when disaster strikes.

Out-of-band (OOB) management
Simplify troubleshooting by managing powered-down devices remotely and accessing critical logs through a dedicated interface.

Dual power supply
Reduce the possibility of power disruptions on a single distribution channel or PDU adversely impacting data and service availability with redundant PSUs.

High-reliability expansion architecture
Redundant SAS links prevent single points of failure from affecting other expansion units, ensuring higher data and service availability.

Powerful networking options
The HD6500 supports a large variety of networking interfaces, protocols, and configurations, whether you need fast sequential transfer, support for simultaneous connections, or high network redundancy.

Built-in fast connectivity
Three Gigabit Ethernet and two 10GbE RJ-45 ports allow for rapid transfer speeds right out of the box.

Mix and match network ports
Add extra 10GbE SFP+/RJ-45, 25GbE SFP28, or Fibre Channel ports in varying configurations by leveraging the four expansion slots.2
