Maximize Service Availability, Minimize Downtime Synology SA3200D features a dual controller architecture to ensure operations and core business functions are not severely impacted by a disaster or unplanned incident that take critical systems offline. The hardware redundancy mechanism leverages controllers, power supplies, and fans to prevent a single point of failure. Powered by the intuitive and feature-rich operating system DiskStation Manager (DSM), SA3200D provides comprehensive protection for network, file services, and applications. Designed with High Availability and Scalability Synology SA3200D is a cost-effective yet highly available data management solution for enterprises, with a competitive priceperformance ratio of $0.05 per gigabyte. Underneath the 2U chassis are dual controller modules in an active-passive architecture, each connected to the other by the reliable, high-speed Non-Transparent Bridge (NTB) with low latency. Service continuity is also backed up by the hardware redundancy mechanism of modularized power supplies and fans to prevent a single point of failure. With SA3200D, you can start small and grow in the future. It supports up to 12 x 3.5"/2.5" SAS interface drive slots by default, and the capacity can be further scaled up to 576 TB using two RXD1219sas4 expansion units, with minimal performance impact3. Data replication is not needed for the shared storage design, saving valuable rack space and network bandwidth when compared with two devices using Synology High Availability. Real-Time Protection with Automatic Failover With an active-passive design consisting of dual controller modules and the built-in Synology High Availability (SHA) service, SA3200D is built to provide a real-time, system-level protection to maximize service availability. It actively monitors network status and critical file services of CIFS, iSCSI, AFP, FTP, NFS, and Synology Directory Server. Once a controller module or the service is unavailable, the system will fail over automatically within a minute1 to minimize system interruption and ensure service continuity. Easy to Deploy, Easy to Manage SA3200D is designed to help IT administrators easily deploy and manage a highly available data management infrastructure. The system features straightforward, wizard-based GUI setup processes that allow you to build up a highly available service environment within minutes. Service status monitoring is made easy and intuitive. Powered by DiskStation Manager (DSM), an intuitive, user-friendly webbased operating system across Synology hardware platforms, SA3200D provides IT administrators a unified user experience without the need to adapt to different user interfaces and complex configuration settings. With a full suite of software applications supported in the Package Center, you can download and install a variety of packages including backup, data protection, and virtualization. Built for Your SAN Storage Needs Synology SA3200D provides a fully certified virtualization solution with VMware® vSphere™, Microsoft® Hyper-V®, Citrix® XenServer™, and OpenStack Cinder. It supports both iSCSI and NFS protocols and integrates with VMware VAAI and Microsoft ODX, allowing IT administrators to effectively deploy and facilitate storage operations in various virtualization environments. IT administrators can efficiently manage virtualized workloads through built-in DSM features and addon plugins for VMware and Windows environments. Features including fast clone, NFS v4.1, and thin provisioning delivers more flexibility to accommodate to administration needs. With no additional license fees required, your virtualized workload can be further protected by a complete suite of data protection applications including Synology Snapshot Replication, Hyper Backup, and Active Backup for Business to cover various protection scenarios. Virtualize Workloads Flexibly in a Protected Environment Synology Virtual Machine Manager (VMM) is an intuitive hypervisor software application allowing you to easily set up virtual machines and run various operating systems, including Windows, Linux, and Virtual DSM. By integrating the computing and the storage nodes into one system, single vendor support experience is achieved to lower the management cost. With VMM, each virtual machine can be fully protected by a set of disaster recovery features including instant snapshot, replication, clone, and restore, safeguarding your virtual machines without additional cost.
