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/write1
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 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.2
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.
Synology Drive is a private cloud management and access solution that enables remote data access, synchronization, on-demand file restoration, and backup via desktop and mobile applications. Sync data between different platforms and devices, and access your organization’s files through mobile apps, desktop clients, and a browser-based interface. Set granular file and folder access and sharing permissions. Maintain a full overview of file activities and track file share settings changes with detailed records in the advanced Synology Drive Admin Console. Learn more
Leverage SMB or NFS shares to provide efficient access to company files over the local network or VPN. Manage data access privileges with access control lists (ACL) though Active Directory/LDAP integration and protect files against tampering or removal with built-in snapshot technology.
Make sure branches or teams always have up-to-date copies of crucial documents and data available locally by syncing folders one or two-way using Synology Drive ShareSync. Let your Synology systems update files across locations each time there is a change to efficiently keep all stakeholders on the same page. Learn more
Securely synchronize files and data from the HD6500 to Synology systems across different sites or offices, and back, by leveraging hybrid cloud technology with Synology Hybrid Share.3 Synchronize large sets of data to the cloud, and leverage the powerful bandwidth of our data centers to stream requested files to local NAS deployed at branch offices, no matter their size. Frequently used files are kept stored on local NAS to provide users access at LAN speeds and can also be pinned manually to prevent them from being removed from the cache. Learn more
Protect large numbers of PCs, servers, Synology systems, and hypervisors, or back up your backup servers with a central storage solution.
Use Hyper Backup to back up files, LUNs, installed applications, and system configurations from tens or hundreds of Synology servers to your HD6500. Set and forget backup tasks with regular schedules, enhance security with fine-grained user permissions and encryption, reduce backup sizes with built-in deduplication, and restore data flexibly with multi-versioning. Learn more
Snapshot Replication enables configurable point-in-time snapshots of shared folders and LUNs with an RPO as low as 5 minutes and recovery within seconds. Learn more
Centrally manage bare-metal backups of all your Synology servers from a single centralized console on your HD6500. Leverage built-in deduplication technology to reduce backup sizes and multi-versioning to allow flexible restoration.
Securely back up Windows clients and servers, Linux endpoints, Synology servers, and VMware® and Hyper-V® virtual machines to the HD6500 with Active Backup for Business. Coordinate all data protection from the centralized management console and choose between bare-metal or file-level restoration, while leveraging built-in deduplication technology to reduce backup sizes.

Protect full Microsoft 365 and Google Workspace accounts by maintaining complete offline copies of your crucial information and configurations with Active Backup for Microsoft 365 and Active Backup for Google Workspace.
Manage distributed deployments of hundreds of local recording servers and thousands of IP cameras centrally. Learn more
Connect up to 650 IP cameras4 from a selection of over 8,300 validated models to the HD6500 itself, or connect hundreds more by adding recording servers at the edge. Easily add storage as deployments grow.
Manage up hundreds of Synology NAS or NVR recording servers from one host, store copies of all or some recordings centrally, and monitor all streams from one interface with Surveillance Station Centralized Management System.
Admins can set detailed rules for who can check live streams or review recordings and footage can be protected against unauthorized access with industry-standard AES-256 encryption.
Watch and analyze live streams or recordings from web browsers, desktop clients, or mobile apps.
Automatically locate cameras within a set IP range or configure units in batch by importing spreadsheets and conveniently replicate settings to new cameras.
Preview footage directly on multi-floor, multi-location maps when events are detected to stay on top of your deployment, with Google Maps and OpenStreetMap integration to make geographically spread-out deployments easier to monitor.
Record each camera’s footage to two Synology servers simultaneously for added redundancy and instant access — for instance, to a smaller device at the edge and a larger central management server. Stream feeds directly to the cloud with C2 Surveillance for fast access and convenient sharing whenever you need evidence.3
Add support for deep learning-powered algorithms and detection profiles such as intrusion detection, license plate recognition, congestion alerts, and face recognition by joining Deep Learning NVR servers to your deployment.
Take advantage of a host of native productivity, management, and security solutions available in the web-based Synology DSM operating system.
Conveniently manage your fleet of Synology NAS from a centralized console.
Secure data with comprehensive built-in security tools to protect your devices against evolving threats.
Seamless transition between clustered servers in the event of a server failure to minimize the impact on applications.
