QNAP TL-D400S 4-Bay Tower SATA JBOD Expansion

Dedicated SATA Expansion for Storage That Keeps Growing The QNAP TL-D400S adds drive space to a supported NAS, computer or server through a dedicated SATA connection. Its tower design brings 4 drive positions into one enclosure, with a supplied host card and matching cables to help plan a complete installation. Use it for an additional storage pool, an archive or a separate backup destination, with RAID and applications managed by the connected system. Highlights The Right Drive Layout 4 drive positions for the supported disk types. Drives are separate; exact compatibility matters. A Defined Host Connection Dedicated SATA connection with bundled host card. Host, cable and firmware requirements stay explicit. Practical Installation Powered enclosure with active cooling. Compact tower format with service access. Storage with a Recovery Plan Host-managed applications and camera entitlements. Independent backup remains a separate requirement. Key Features A Direct Path to Each Drive The enclosure exposes drive groups over 1 SFF-8088 connection. Each cable carries dedicated SATA lanes instead of making every drive share one USB link. Choose an appropriate PCIe slot and connect the cable groups correctly. The aggregate link rates describe the interface architecture; they are not a guarantee of one file-transfer speed. The Host Card Is Part of the Package The current manufacturer package includes the QXP-400eS-A1164 and 1 matching 1m cable. The adapter still needs a compatible host, sufficient PCIe bandwidth and the correct firmware or driver. This is SATA storage using Mini-SAS connectors, so a cable that fits is not proof of SAS-drive or third-party-controller compatibility. Keep the NAS Storage Layout Clear Host-managed software RAID. On NAS, use a separate pool or volume; it cannot extend the internal NAS pool and NAS applications cannot be installed on this enclosure. Storage management and snapshots depend on the supported host operating system. Plan usable capacity after RAID overhead, retain a separate backup and check the approved connection procedure before attaching or disconnecting the enclosure. Monitor the Enclosure from Your Working System Storage & Snapshots on a supported NAS; QNAP JBOD Manager monitors enclosure and disk health on supported Windows/Ubuntu systems. The computer operating system manages its software RAID. Review drive health, temperature and fan alerts during operation. A larger chassis adds storage positions but does not upgrade the host processor, memory, application compatibility or camera licences. Install for Access and Airflow The tower enclosure measures 168.5 × 160.2 × 219mm H × W × D, excluding feet. Tower installation; leave ventilation and cable clearance. Dimensions exclude feet, which may add up to 30mm depending on model. 65W AC adapter; 100–240V AC input. Supply ratings are power capacity, not constant operating consumption. Keep Backup and Recording Requirements Separate The enclosure adds storage, not a standalone surveillance recorder. Maximum camera channels, included licences, recording performance and retention depend on the host NAS and recording software. Expanding disk space does not automatically increase those limits. Maintain a separate current backup and a tested recovery plan. Any optional NASCare scope must be confirmed for the registered NAS and attached configuration. Summary The TL-D400S is a practical way to add direct SATA drive capacity when the complete connection and storage layout have been planned. Match the host, drives and installation hardware first, then size RAID, recording retention and separate backups around the work. This keeps the expansion useful, serviceable and clear to maintain. Frequently Asked Questions Can this work as a standalone NAS?ExpandCollapse No. This is an expansion or direct-attached storage enclosure. It requires a compatible NAS or computer and does not offer independent Ethernet file sharing, NAS applications or surveillance recording. Can I use SAS drives or connect any Mini-SAS card?ExpandCollapse No. These drive bays use SATA. The SFF connector is only the physical connector type; use the supplied or specifically qualified QXP SATA adapter and the correct cable. SAS-drive and arbitrary third-party-card support must not be assumed. Which drives can I install?ExpandCollapse 4 × 3.5-inch drive positions supporting compatible 3.5-inch SATA HDDs and 2.5-inch SATA SSDs; SATA 6Gb/s and 3Gb/s. Keep HDD and SSD types in separate RAID groups. Verify exact drive model, firmware, sector format and capacity compatibility. Drives are sold separately. Which host and software do I need?ExpandCollapse Qualified QNAP NAS with a compatible PCIe slot, supported QXP SATA card and QTS 4.4.2 or QuTS hero h4.5.0 or later; or a compatible Windows/Ubuntu computer with the correct adapter and drivers. Not supported on macOS. On NAS, the expansion pool remains separate from internal storage. What is included, and do I need rack rails?ExpandCollapse Enclosure, QXP-400eS-A1164 SATA expansion card, 1 × 1m SFF-8088 to SFF-8088 cables, power cord, AC adapter, drive mounting screws and Quick Installation Guide. Drives and any rack rail kit are separate. Tower installation; leave ventilation and cable clearance. Dimensions exclude feet, which may add up to 30mm depending on model. Will it increase my maximum surveillance camera count?ExpandCollapse Adding drive space may extend recording retention, but it does not add camera licences or increase the host CPU, memory or software limits. Check the exact NAS, recording application, licence entitlement and workload. RAID and attached expansion are not replacements for an independent backup. 続きを読む
