Designed for high reliability

The HD6500 is built to keep mission-critical data and services accessible, so that vital work can continue 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 wide 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 high transfer speeds right out of the box.

Mix and match network ports
Add up to 10 extra 10GbE SFP+/RJ-45, 25GbE SFP28, or Fibre Channel ports in varying configurations.

Failover and network balancing
Bond multiple network interfaces with Link Aggregation to enable automatic network failover and load balancing.

Massive file server

Host and retrieve very large files from extensive archives whenever needed. Provide user friendly access and set up powerful cross-site syncing.

Private cloud

A private cloud suite for file sharing
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.

Cross-site syncing
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.

Cross-site syncing

Secure site-to site file and folder syncing
Make sure branches or teams always have up-to-date local copies of crucial documents and data by syncing folders one or two-way using Synology Drive ShareSync. Let your Synology systems update files across locations with each change to efficiently keep all stakeholders on the same page.

Efficient cross-site syncing through the cloud
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.4 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.

Central backup server

Protect large numbers of PCs, servers, Synology systems, and hypervisors, or back up your backup servers with a central storage solution.

Back up Synology storage systems

Backup destination for shares and LUNs
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. 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.

Bare-metal backup for Synology NAS
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.

Back up Windows and Linux endpoints

Bare-metal PC, server, and VM backup
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.

SaaS protection with local backups
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.

Main surveillance storage

Manage distributed deployments of hundreds of local recording servers and thousands of IP cameras centrally.

Centralized, secure, and scalable surveillance

Flexible scaling and expansion
Connect up to 150 IP cameras5 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.

Central management and recording
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.

Secure and private video storage
Set detailed access rules to define which users can view live streams or recordings, and protect footage against unauthorised access with industry-standard AES-256 encryption.

Anywhere access with multiple clients
Watch and analyze live streams or recordings from web browsers, desktop clients, or mobile apps.

Advanced deployment and analysis options

Batch and automated camera deployment
Automatically locate cameras within a set IP range or configure units in batch via spreadsheet import, and conveniently replicate settings to new cameras.

Instant event streaming on multi-location maps
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.

Dual recording, locally and to the cloud
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.

Event detection and smart analytics options
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.
