Accelerate Mission-Critical Virtualization Workloads With Dual-Controller High-Availability SAN Architecture Engineered For Uncompromising Business Continuity
The Synology UC3400 is an enterprise-grade 12-bay 2U rackmount SAN enclosure engineered specifically to deliver zero-downtime block storage services for mission-critical virtualization and enterprise databases. Featuring an active-active dual-controller architecture, both processing nodes operate concurrently to ensure continuous data access over iSCSI and Fibre Channel protocols even in the event of a hardware failure on one controller. Powered by dual 8-core Intel Xeon D-1541 processors (one per controller) and 16GB of DDR4 ECC UDIMM system memory (expandable up to 128GB total), the UC3400 achieves outstanding performance exceeding 180,000 4K random write IOPS. Supporting 12 hot-swappable dual-port SAS HDDs and SSDs, this SAN system serves as a rock-solid storage backbone for high-density virtualization setups. Available now across Bangladesh, TechDistri brings you this authentic Synology SAN solution complete with verified local warranties and dedicated technical support.
To seamlessly support high-speed corporate networking environments, each controller on the UC3400 comes pre-equipped with an integrated 10GbE RJ-45 port and dual 1GbE RJ-45 ports. For enterprise deployments requiring higher network throughput or dedicated Fibre Channel integration, each controller features a PCIe 3.0 x8 expansion slot. IT managers can easily install optional 10GbE or 25GbE network interface cards or 16Gb Fibre Channel host bus adapters (HBAs), providing low-latency execution and high-bandwidth transmission across enterprise storage networks.
Designed to scale effortlessly with expanding storage demands, the UC3400 can expand up to 36 drive bays by connecting two Synology RXD1219sas dual-controller expansion units, supporting up to 576TB of raw storage capacity. Running specialized SAN management software, the system provides native application-aware Snapshot Replication for iSCSI LUNs, enabling instant disaster recovery and virtual machine restoration. Additionally, support for Self-Encrypting Drives (SEDs) delivers hardware-level data encryption at rest for sensitive enterprise files.
The UC3400 is fully certified for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack environments, supporting advanced storage offloading integration like VAAI, ODX, and ALUA. Featuring dual redundant 500W power supply units and hot-swappable dual-port SAS architecture, the unit eliminates single points of hardware failure. Backed by a 2-year limited manufacturer warranty, this 2U active-active SAN server provides guaranteed uptime for critical enterprise operations.
Secure your professional enterprise storage and networking hardware with absolute confidence. TechDistri stands as your premier destination in Bangladesh for authentic Synology hardware, providing verified local warranties, competitive market pricing, and dedicated technical assistance to ensure your core IT infrastructure operates flawlessly.
