- CPU : 2 x 10-core Intel Xeon Silver
- Throughput : Over 6,688/6,662MB/s sequential read/write
- Memory : 64 GB DDR4 ECC, expandable to 512 GB
- Scalability : Expand to 300 drives with four RX6022sas expansion units
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
Failover and network balancing
Bond multiple network interfaces with Link Aggregation to enable automatic network failover and load balancing.
Consolidate your data storage
Back up your backup solutions, bring all your files together in one place, or bring distributed surveillance deployments under central control.
Massive file server
Host and retrieve massive files from extensive archives whenever needed. Provide user friendly access and set up powerful cross-site syncing.

Notes:
- Model specifications are subject to change without prior notice.
- The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time.
- The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations.
- If usage requirements exceed the specifications above, please contact our regional partners for professional advice.
