60-bay RackStation (up to 300-bay) 2.5'' or 3.5" SAS storage, 10 Core 2.4 GHz (turbo to 3.2 GHz), 64GB RAM (up to 512GB), 2x10GbE Base T, Redundant power. Scalable high-density storage server for multi-petabyte applications
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.
2 x 10-core Intel Xeon Silver
Over 6,688/6,662MB/s sequential read/write
64 GB DDR4 ECC, expandable to 512 GB
Expand to 300 drives with four RX6022sas expansion units
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.
The HD6500 is built to keep mission-critical data and services accessible, so that businesses can continue to perform even when disaster strikes.
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.
Three Gigabit Ethernet and two 10GbE RJ-45 ports allow for rapid transfer speeds right out of the box.
Add extra 10GbE SFP+/RJ-45, 25GbE SFP28, or Fibre Channel ports in varying configurations by leveraging the four expansion slots.
Bond multiple network interfaces with Link Aggregation to enable automatic network failover and load balancing.
Back up your backup solutions, bring all your files together in one place, or bring distributed surveillance deployments under central control.
Host and retrieve massive files from extensive archives whenever needed. Provide user friendly access and set up powerful cross-site syncing.
Protect large numbers of PCs, servers, Synology systems, and hypervisors, or back up your backup servers with a central storage solution.
Manage distributed deployments of hundreds of local recording servers and thousands of IP cameras centrally.
