From the trusted brand Synology comes the UC3200 12-Bay iSCSI Unified Controller with Intel Xeon D-1521, a high-performance, reliable, and user-friendly network-attached storage (NAS) solution. This advanced device is designed to deliver uninterrupted iSCSI services, thanks to its high-availability architecture housed in a single chassis. The UC3200 features dual controllers that work in tandem, ensuring automatic failover in the event of a disaster, thus maintaining continuous service. It boasts 12 drive bays compatible with both 3.5" and 2.5" HDD/SSD, offering a maximum raw capacity of 576TB through its high-performance SAS interface. For enhanced data security, the UC3200 supports Self Encrypting Drive (SED) technology, encrypting all data to the hard drives at the hardware level. It also comes equipped with a redundant, modularized 500W power supply, ensuring service continuity even in the event of a power supply failure. The UC3200's dual controller modules work simultaneously, providing high performance and non-disruptive iSCSI services. It also features a PCIe 3.0 slot, allowing for network bandwidth enhancement with optional 10GbE/25GbE network interface cards' expansion. This NAS solution is powered by an Intel Xeon D-1521 4-core 2.4 GHz processor, capable of bursting up to 2.7 GHz. This, coupled with the dual CPUs, delivers enterprise-class performance of 140,000 4K random write IOPS with low latency. The UC3200 also includes 4 DDR4 memory slots with 8GB ECC UDIMM, expandable up to 64GB, to boost system performance. It features redundant, modularized fans for easy maintenance and replacement, minimizing service downtime. Designed with a dedicated SATA DOM, the UC3200 isolates the operating system from the regular data stored in hard drives. It also utilizes a Non-Transparent Bridge (NTB) to connect two controller modules at high speed and instantly sync memory data between the controllers, preventing cached data loss when one controller is unavailable. Optimized for virtualization environments, the UC3200 is integrated with VMware vSphere 6.5, Microsoft Hyper-V, and VAAI to offload storage operations and optimize computational efficiency. It also supports Windows Offloaded Data Transfer (ODX) to speed up data transfer and migration rates. The UC3200 is designed with an operating system, DSM UC, that simplifies management by allowing you to oversee the two controllers from one single portal. It also includes built-in monitor applications that display the status at a glance and send prompt notifications when important events occur. Finally, the UC3200 ensures your critical data is disaster-proof with its Snapshot Replication feature, offering schedulable and near-instantaneous data protection. It supports up to 4,096 system-wide snapshots for local volumes or offsite servers, providing application-aware snapshot protection and instant recovery of virtual machines in iSCSI LUNs in the event of a disaster.
