• Unmatched data integrity with QuTS hero: The TVS-h874-i5-32G runs QuTS hero, a ZFS-based operating system that encrypts, protects, and preserves data with end-to-end checksums, continuous integrity verification, and efficient data services. This foundation reduces the risk of silent data corruption and enables reliable disaster recovery through point-in-time snapshots, instant clones, and flexible replication. Advanced data management features—such as compression, deduplication, and scrubbing—optimize storage usage while maintaining high levels of performance for multi-user environments and virtualization workloads.
• Blazing-fast networking with PCIe Gen4 upgrades: Expandable PCIe Gen4 support unlocks 10GbE and 25GbE network connectivity, delivering throughput that scales with your organization’s needs. Whether you’re migrating large VMware or Hyper-V workloads, performing rapid backups to remote sites, or streaming high-resolution media across the LAN, TVS-h874-i5-32G maintains low latency and high IOPS even under heavy load.
• M.2 NVMe caching for ultra-responsive performance: The system includes dedicated M.2 NVMe caching slots to accelerate frequently accessed data. By placing active data on fast NVMe cache, read/write latency decreases dramatically, improving virtual machines, databases, and file-serving operations. Cache tiers work in harmony with the main HDD/SATA storage, enabling a balanced, cost-efficient approach to performance and capacity.
• Powerful virtualization-ready platform: With a multi-threaded Intel Core i5 six-core processor and abundant memory, TVS-h874-i5-32G delivers solid performance for virtualization stacks, containers, and multi-user workloads. QuTS hero’s virtualization features complement Virtualization Station and Container Station, enabling secure, isolated environments on a single NAS/SAN appliance while supporting high-availability configurations and rapid VM deployment.
• Flexible storage with scalable bays and hybrid cloud: The TVS-h874-i5-32G supports multiple drive bays and a choice of 3.5" or 2.5" SATA drives, plus M.2 caching for hot data. Its flexible RAID-like pool management, plus cloud integration options, lets you build a scalable storage strategy that grows with your data. Hybrid cloud capabilities enable offsite backups, remote replication, and seamless cloud tiering, helping protect against local site risks while enabling rapid disaster recovery and flexible collaboration across locations.
