Reliability and High Availability
Active-active dual controllers work simultaneously to ensure zero downtime in the event of a controller failure while the non-transparent bridge (NTB) enables inter-domain communication to maximize the protection of in-flight data.
Active-Active SAN with enterprise-class performance
Designed for mission-critical environments, UC3400 is a high-availability SAN solution supporting Fibre Channel (FC) and iSCSI protocols. With over 180,000 4K random write IOPS,1it supports a wide range of demanding workloads.
Virtualization-ready
Full certification for VMware, vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack environments
Support for Windows Offloaded Data Transfer (ODX), VMware vSphere Storage APIs Array Integration (VAAI), and ALUA ensure optimized and efficient storage operations
OpenStack®Cinder support enables UC3400 to become a block-based storage component
Flexible network options
Boost network from 10GbE and dual 1GbE RJ-45 ports to 10/25 Gb Ethernet cards or 16 Gb Fibre channel host bus adapters on each controller.2
Built-in data protection and security
Maximize service uptime for critical services and enhance data security with snapshot protection and self-encrypting drive support in UC3400.
Snapshot Replication
Built-in software offers application-aware snapshot protection and instant recovery of virtual machines in iSCSI LUNs in the event of a disaster.
Self-encrypting drive support
Storage expansion
Simple capacity expansion of up to 576 TB of raw storage is available with two Synology RXD1219sas Expansion Units.3
Performance backed by Synology drives
Leverage high sustained performance and reliability with enterprise-grade drives with built-in protection designed for Synology systems.
