QNAP TS-h2490FU 24-Bay NVMe All-Flash Rackmount NAS

Dense NVMe Storage for a High-Speed Data Environment The QNAP TS-h2490FU houses twenty-four U.2 NVMe SSD bays in a 2U rackmount chassis. AMD EPYC processing, ECC RDIMM memory and 25GbE networking provide a platform for virtual machine storage, shared production data and other workloads that need an all-flash storage architecture. Its configuration matters beyond installed memory. Eight-core versions include two 25GbE SFP28 ports, while sixteen-core versions include four. The Configuration selector keeps processor core class and memory together so the networking and processing specification remains clear. Highlights Twenty-four 2.5-inch U.2 NVMe PCIe Gen3 x4 SSD bays AMD EPYC processing with ECC DDR4 RDIMM memory Two or four 25GbE SFP28 ports according to processor configuration Five PCIe Gen4 slots, with supplied network adapters occupying slots Redundant power supplies and five-year warranty Key Features NVMe Throughout the Main Storage Bays All twenty-four positions are intended for qualified U.2 NVMe SSDs. This is a dedicated NVMe design: SATA SSDs and hard disk drives are not supported in the main bays. Select enterprise SSDs with suitable endurance, power-loss protection and QNAP compatibility approval. Match Processing and Network Capacity Choose an eight-core EPYC 7232P or qualified 7252 revision, or a sixteen-core EPYC 7302P configuration. Dual 2.5GbE ports are complemented by two or four 25GbE ports according to configuration. Confirm the supplied processor revision and port arrangement when specifying a project. Memory and Expansion for the Storage Design Sixteen ECC RDIMM slots provide an upgrade path for memory-intensive storage services. Five PCIe Gen4 slots support selected expansion cards, with shared lanes and supplied adapters affecting the usable slots. Design the storage network and expansion layout before deployment. ZFS Protection with a Planned RAID Layout QuTS hero supports checksummed storage, snapshots and replication. For a large SSD pool, plan multiple RAID groups within the operating system limits rather than assuming a single twenty-four-drive RAID group is appropriate. Keep an independent backup for recovery beyond the NAS. Summary The TS-h2490FU is a dense NVMe platform for organisations designing a high-speed storage environment. Choose its processor and network configuration together, then plan qualified SSDs, RAID groups, rack power, cooling and independent backup as one system. Frequently Asked Questions Which configuration should I choose?ExpandCollapse Use the Configuration selector to choose the processor class and installed memory together. Size the CPU, RAM, drives and networking for the actual applications and number of users. The SKU shown for your selection identifies the exact configured offer. Which drives can I install?ExpandCollapse 24 × 2.5-inch U.2 NVMe Gen3 x4 SSD bays; SSDs separate. SATA drives and HDDs are not supported. Check each exact drive against QNAP’s compatibility list before ordering; usable capacity depends on the RAID and file-system design. Are the advertised network ports built in?ExpandCollapse 8-core configurations: 2 × 25GbE SFP28. 16-core configurations: 4 × 25GbE SFP28. All configurations also have 2 × 2.5GbE RJ45. Transceivers, network cables, switches and optional adapters are separate unless explicitly included. How many surveillance camera licences are included?ExpandCollapse On a supported QVR Surveillance installation, two camera channels are included and six more can be claimed after registration, giving eight free channels. QVR Pro offers eight included channels on supported QTS configurations. Extra-channel availability depends on the NAS and QVR version; confirm compatibility and licensing before planning beyond the free entitlement. Camera count also depends on bitrate, resolution, recording settings, storage and other workloads. Can this NAS run virtual machines and containers?ExpandCollapse Supported Virtualization Station and Container Station packages provide virtual machine and container functions. Virtualization Station requires at least 4GB RAM and Container Station at least 1GB; these are installation minimums, not a workload sizing recommendation. Allocate additional resources for the guest systems and NAS services. Does RAID replace an independent backup?ExpandCollapse No. RAID helps with selected drive failures, while snapshots can recover earlier versions under the right conditions. Neither is a complete independent backup. Keep a separate, current backup and test restoration; ransomware, deletion, theft or damage can affect data that remains only on the NAS. 더 보기
