QNAP TL-R2400PES-RP 24-Bay Rackmount PCIe SATA Expansion

Scale QNAP Storage Through a Dedicated PCIe Link The QNAP TL-R2400PES-RP adds 24 drive positions to a compatible QNAP storage system in a 4U rackmount chassis. Its dedicated PCIe connection supports large SATA storage configurations while keeping storage management on the host NAS. Redundant power supports the hardware installation, while the exact host, adapter, cables and RAID design determine the usable capacity and resilience. It is an expansion enclosure rather than an independent NAS. Highlights The Right Drive Layout 24 drive positions for the supported disk types. Drives are separate; exact compatibility matters. A Defined Host Connection QNAP PCIe JBOD connection. Host, cable and firmware requirements stay explicit. Practical Installation Redundant power supplies. Exact optional rail kit required for rack installation. Storage with a Recovery Plan Host-managed applications and camera entitlements. Independent backup remains a separate requirement. Key Features Match the Connection Before You Expand PCIe storage connection through paired external SFF-8644 input/output connectors. This uses the QNAP PCIe JBOD protocol, not SAS, despite the connector shape. Qualified QNAP NAS with QTS 5.1.2 or QuTS hero h5.1.2 or later, required model-specific BIOS and a supported QXP-3X8PES or QXP-3X4PES card. Cards and matching special PCIe cables must be selected together. Manage Storage as Part of the NAS Host-managed RAID and supported storage pools. Existing-pool expansion can be supported by adding a new enclosure RAID group; confirm host OS, firmware, pool limits and complete topology. Keep each volume within one chassis where practical. The enclosure does not add CPU, RAM, network ports or application entitlements to the host. Size the complete system for the intended users, backup traffic and retention requirements. Build Resilience Around the Complete Path Supported cascading depends on the host NAS and specified input/output wiring. The special paired PCIe cable is different from an ordinary Mini-SAS cable. Redundant power supplies help address a power-module fault; they do not protect against every failure or replace separate backups. Plan Capacity Without Overpromising 24 × 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. Usable storage is lower than raw drive capacity after RAID, file-system and any reserve overhead. Confirm recovery objectives and keep important data backed up separately before changing a storage layout. Install for Access and Airflow The 4U rackmount enclosure measures 176.15 × 442.4 × 630.2mm H × W × D, excluding rack ears and protruding power-supply fittings. Optional RAIL-A02-90. Confirm cabinet depth, rack-post spacing and rear cable/service clearance. 2 × 550W redundant power supplies; 100–240V AC. 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-R2400PES-RP is a practical way to add dedicated PCIe-connected SATA 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. Is this an ordinary SAS enclosure?ExpandCollapse PCIe storage connection through paired external SFF-8644 input/output connectors. This uses the QNAP PCIe JBOD protocol, not SAS, despite the connector shape. Which drives can I install?ExpandCollapse 24 × 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 QTS 5.1.2 or QuTS hero h5.1.2 or later, required model-specific BIOS and a supported QXP-3X8PES or QXP-3X4PES card. Cards and matching special PCIe cables must be selected together. Supported cascading varies by host NAS, host card and BIOS. Follow the specified input/output wiring; enclosure counts and pool limits are not universal. What is included, and do I need rack rails?ExpandCollapse Enclosure, 2 power cords, 2 tray keys, drive mounting screws, 1 × 1m CAB-PCIE10M-8644-8X cable and Quick Installation Guide. Host PCIe card, drives and rails are separate. The included 8X cable is for QXP-3X8PES; QXP-3X4PES requires its matching 4X cable. Optional RAIL-A02-90. Confirm cabinet depth, rack-post spacing and rear cable/service clearance. 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. Magbasa pa
