2019: Unified Controller UC3200

On November 15, 2019, the company Synology introduced the Unified Controller UC3200 - a server dual-controller controller designed for highly available services data iSCSI in mission-critical enterprise environments, as well as a RXD1219sas expansion module.

"A common problem facing enterprises ITadministrators is finding an iSCSI solution with virtually zero downtime, a simple user interface, and accessibility. total cost of ownership To solve these problems, the Unified Controller UC3200 has been developed. UC3200 is IP SAN an Active-Active architecture solution that maximizes service uptime and is intuitive operating system for administrators to manage two controllers from one, portal simplifying management and reducing learning time. " noted Jason' Fan, Product Manager, Synology Inc. '

According to the developer, thanks to the 4-core Intel Xeon processor with a clock speed of 2.4 GHz and DDR4 ECC UDIMM memory with a capacity of 8 GB per controller, UC3200 provides more than 140,000 I/O per second for arbitrary writing in blocks of 4 KB in an aggregated 10GbE environment. Characteristics of the UC3200:

• Memory. 8 GB DDR4 ECC UDIMM (expandable up to 64 GB);
• Built-in 10GbE ports. 1 port 10GbE and 2 ports 1GbE Ethernet with support for failover and Link Aggregation
• PCIe expansion: 1 PCIe 3.0 slot for additional network card;
• Scalability. 12 default SAS drive bays, scaling up to 500 TB with two RXD1219sas2;
• Modular design. Major system components, including SAS modules and system fans, can be replaced to maximize system uptime.

"Configuring Synology UC3200 is effortless, not to mention smoothly failover between two Active-Active controllers when there is any problem with the virtual storage system. Synology UC3200 the right choice for companies that need iSCSI storage for their virtualization environment because it delivers high reliability and performance at a bargain price. " tagged Tony Chen, Technical Support Manager at Unitech Computer

According to the developer, thanks to the hardware solution, UC3200 allows companies to achieve almost zero service downtime and simplify IT operations:

• Opaque Bridge (NTB). You can allow one controller to quickly switch services to itself if the other controller fails;
• Self-encrypting disk (SED). Support for data encryption to protect critical data at the hardware level;
• Built-in DOM drive with SATA interface. You can isolate the operating system from critical data;
• Secure cache protection. You can synchronize cached data between two controllers to prevent data loss in the event of a controller failure before writing data to hard drives;
• 5-year warranty.

As noted in Synology, UC3200 provides convenient integration of proven iSCSI virtualization with the most common hypervisors:

• iSCSI compliance - ALUA. Allows hosts to define optimized paths to improve data performance and efficiency;
• App snapshots. Provides a virtual disaster recovery plan for virtualized workloads;
• Virtualization support. Certified for VMware vSphere 6.5, Microsoft Hyper-V, Citrix XenServer, and OpenStack Cinder.

RXD1219sas is a 2U expansion module and the optimal upgrade solution storage systems for UC3200. The user can add up to 12 additional SAS 2,5 "/3.5 "drive bays without stopping the system by connecting UC3200 and RXD1219sas devices directly through the mini-SAS HD cable, and replace critical system components including SAS modules and system fans to ensure maximum system uptime.

Characteristics of the RXD1219sas marked by the manufacturer:

• Scalability. Simple design to easily increase storage capacity;
• Performance. Mini-SAS HD for high-performance data transfer;
• Reliability. Redundant power supplies to maximize continuous operation time.
