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. 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 up to 10 extra 10GbE SFP+/RJ-45, 2
