Equipping your data center and high-bandwidth network installation with the QNAP TDS-h2489FU-4314-128G 24-Bay NAS Enclosure helps to provide you with sufficient capacity and performance for use in large-scale file serving, virtual machines, 8K media production, and other demanding applications. Designed to support all solid-state storage devices, up to twenty-four 2.5" U.2 NVMe PCIe 4.0 x4 or SATA III drives may be installed into its available bays and configured for RAID 0, 1, 5, 6, 10, 50, 60, or Single modes with up to triple parity and triple mirroring. Performance may be further enhanced by installing up to two M.2 2280 PCIe 3.0 or SATA cache drives. The TDS-h2489FU-4314-128G is also outfitted with dual 2.4 GHz Intel Xeon Silver 4314 16-core processors with 128GB of ECC DDR4 memory between them and integrates with your network through its four 2.5G RJ45 and two 25G SFP28 ports. The SFP28 network adapter is already installed into the PCIe 4.0 x8 slot, leaving the x16 slot free for additional NICs and other expansions.

When fully configured with U.2 NVMe PCIe 4.0 SSDs and six 25G Ethernet ports, the TDS-h2489FU can reach sequential read and write speeds of up to 16,165 MB/s and 11,022 MB/s respectively in RAID 50. This NAS has QuTS hero operating system preinstalled.

Supporting all NVMe flash storage, the TDS-h2489FU is designed to deliver high random read and write IOPS for tackling I/O-intensive and latency-sensitive applications.

Inline data deduplication and compression, pool over-provisioning, and TRIM maximize SSD performance and lifespan.

Dual 25G SFP28 and quad 2.5G RJ45 high-speed connectivity accelerates virtualization, intensive file access, and large backup/restoration tasks.

The dual-port 25G SFP28 SmartNIC features an NVIDIA Mellanox ConnectX-6 Lx controller that supports iSCSI Extensions for RDMA (iSER) to increase performance of data transfer between NAS and ESXi server and offload CPU workloads. With Port Trunking and Auto-Negotiation, the TDS-h2489FU is designed to provide your organization with the bandwidth and reliability to allow thousands of endpoint users to smoothly access data stored on the NAS and satisfy demanding applications.

There are 32 RDIMM ECC DDR4 memory slots are available, providing 16 slots per socket. The TDS-h2489FU also has PCIe 4.0 x16 and x8 slots, with the latter occupied by the SFP28 NIC, for expansions such as network cards, and 12 Gb/s SAS adapters to connect to compatible storage enclosures.

QuTS hero combines the app-based QTS with the 128-bit ZFS file system to provide flexible storage management, comprehensive data protection, and optimized performance to tackle the complexity and performance demands of modern IT. From storage management, virtualization, to collaborative media workflows, QuTS hero streamlines your business-critical tasks.

The TDS-h2489FU supports virtualization storage and hosting virtual machines and containerized apps.

Configure the 2.5" SSDs or up to two M.2 2280 SSDs as cache drives for optimal performance and reduced latency.

Related Questions and Answers

Q: 1. If I install 7 22TB drives and use Raid 5, what minimum size should the 8th (parity) drive be?

A: With the QNAP TVS-h874T 8-Bay NAS Enclosure in a RAID 5 configuration, all drives should be the same capacity.

Q: 2. does this m2 ssd work with my tvs472 WD 500GB Black SN750 NVMe M.2 Internal SSD? BH #WEBG500GB • MFR #WDBRPG5000ANC-WRSN

A: Yes, the two models are compatible drives.

Q: 3. does the thunderbolt 3 port on this support daisy chaining with other devices (e.g. hubs, sound cards, thunderbolt displays)?

A: The unit is listed as supporting storage volumes and displays via the second Thunderbolt 3 port.

Q: 4. can this device support 4x 16tb hdds and 2x 2tb nvme ssds?

A: Yes, this nas is capable of that many drives. 16TB may be too big for the RAID functions.

Q: 5. If I would use this NAS for video editing (4K / 6K B-RAW) should i go with a stronger CPU aka i3 or i5? I would connect the NAS to an iMac pro.

A: I believe you would be fine with this one, considering that you intent to expand the RAM, use the RJ45 (10GbE) and choose the proper hard drive configuration.

Q: 6. How can we mount M.2 NVME drives with it?

A: In the QNAP TS-h2490FU 24-Bay NAS Enclosure, the NVMe will get mounted into a 2.5" enclosure and has a SAS connection on the back of the enclosure.

Q: 7. What is the usable capacity on this 24 bay NAS?

A: The QNAP QNAP TDS-H2489FU-4314 does not come with any storage drives installed, so the storage capacity will depend on the quantity/capacity of drives the user installs, and which level of RAID is used. All levels of RAID consume different percentages of your storage pool to create parity.

Q: 8. Can you connect this device to your main computer using TB3 and still have a remote computer access the drives through the Internet ports?

A: This NAS server also acts as a DAS (direct attached storage) when connected to the Thunderbolt 3 port. You will connect this NAS server to your network via the Ethernet port, to connect remotely with it. When you're next to your NAS server, you can connect to it via the Thunderbolt 3 port for a faster transfer rate.

Q: 9. With one expansion slot used for the Thunderbolt 3 ports, how can I get 2 NVMe M2 2280 SSDs for Q-tiered storage? Do I need to remove the TB3 ports?

A: There is no need to remove the thunderbolt 3 expansion card.

Q: 10. Can a computer connect via usb-c for direct attach?

A: No, this QNAP TVS-h874 8-Bay NAS Enclosure does not connect direct to pc via USB, it's only for connecting hard drives to input into the NAS.
