Best Synology Unified Controller UC3200 SAN Rack (2U) Intel® Xeon® D D-1521 8 GB DDR4 Black, Grey for Business

Delivering reliable, highly available iSCSI services
Realizing high-availability architecture in just one single chassis, the two controllers in Synology UC3200 work simultaneously and can automatically fail over to each other in the event of disaster, delivering services without any interruptions.

12 x 3.5”/2.5” HDD/SSD
High-performance SAS interface drive slots with maximum 576TB raw capacity. Supporting SED (Self Encrypting Drive) to encrypt all data to hard drives, UC3200 provides upmost data security at the hardware level.

Redundant power supply
Modularized and swappable 500W power supply prevents service downtime in the event of a power supply failure.

Active-active controller module
Dual controller modules work simultaneously to provide high performance and non-disruptive iSCSI services.

PCIe 3.0 slot
Further boost network bandwidth with optional 10GbE/25GbE network interface cards' expansion.

2 x 1GbE & 1 x 10GbE
Onboard RJ45 interfaces of 1GbE and 10GbE with the Link Aggregation support.

Mini-SAS HD port
Connect up to 2 x RXD1219sas for flexible plug-and-play volume expansion.

Processor
Armed with Intel® Xeon® D-1521 4-core 2.4 GHz processor burst up to 2.7 GHz, UC3200’s dual CPUs provide enterprise-class performance of 140,000 4K random write IOPS with low latency.

4 x DDR4 memory slots
8GB ECC UDIMM, expandable up to 64GB to boost system performance.

Fan
Redundant, modularized fans for easy maintenance and replacement, minimizing service downtime.

SATA DOM
The dedicated SATA DOM isolates the operating system from the regular data stored in hard drives.

Non-Transparent Bridge (NTB)
Connect two controller modules at a blazingly fast speed and instantly sync memory data between the controllers to prevent cached data loss when one controller is unavailable.

Works with mainstream virtualization systems
Optimized for virtualization environments.

- Integrated with VMware vSphere® 6.5, Microsoft Hyper-V®, and VAAI to offload storage operations and optimize computational efficiency.
- Windows Offloaded Data Transfer (ODX) is supported to speed up data transfer and migration rates.
- Turn Synology UC3200 into a block-based storage component with the support of OpenStack® Cinder.
- Compliance with iSCSI industry standard ALUA allows hosts to identify the optimized paths to increase data transfer performance and efficiency.

A system built exclusively for iSCSI
DSM UC, an operating system designed to ease the learning curve, allows you to manage the two controllers from one single portal. The built-in monitor applications display the status at a glance and send prompt notifications when important events occur, so that IT administrators can stay alert to potential problems and respond in the shortest time possible.

Disaster-proof your critical data
Snapshot Replication is put in place with the support of Btrfs file system, offering schedulable and near-instantaneous data protection. Supporting up to 4,096 system-wide snapshots for local volumes or offsite servers, UC3200 brings application-aware snapshot protection and instant recovery of virtual machines in iSCSI LUNs in the event of a disaster.
