QNAP TL-R1220Sep-RP 12-Bay Rackmount SAS SATA Expansion

Enterprise SAS Expansion Built Around Your Existing NAS The QNAP TL-R1220Sep-RP adds 12 drive positions to a compatible QNAP storage system in a 2U short-depth rackmount chassis. Its SAS interface supports qualified drive and path configurations for larger archives, backup repositories and shared-storage workloads. 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 12 drive positions for the supported disk types. Drives are separate; exact compatibility matters. A Defined Host Connection Four external 12Gb/s SAS wide ports. 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 4 × Mini-SAS HD SFF-8644 SAS wide ports; SAS 12Gb/s host interface with supported link and path configurations. Qualified QNAP NAS with QTS 4.5.1 or QuTS hero h4.5.1 or later and built-in SAS or a supported QXP SAS card. Current listed cards include QXP-1630S-3816 and QXP-830S-3808; exact host compatibility remains required. Manage Storage as Part of the NAS Host-managed RAID, storage pools and supported snapshots. Path redundancy, link aggregation and cascading require a qualified host, adapter and cable topology; redundant power does not mean dual-controller architecture. 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 For supported SAS cascading, confirm the current host and adapter topology. Multipath can provide an alternative cable route only when the NAS, drives and configuration support it. Redundant power supplies help address a power-module fault; they do not protect against every failure or replace separate backups. Plan Capacity Without Overpromising 12 × 3.5-inch positions supporting compatible 3.5-inch SAS 12Gb/s or 6Gb/s HDDs, 3.5-inch SATA 6Gb/s or 3Gb/s HDDs, and 2.5-inch SATA SSDs. 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 2U short-depth rackmount enclosure measures 88.65 × 482 × 370.65mm H × W × D, excluding rack ears and protruding power-supply fittings. Optional RAIL-B02 or RAIL-S02, subject to rack-post spacing. Confirm cabinet depth, rack-post spacing and rear cable/service clearance. 2 × 300W 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-R1220Sep-RP is a practical way to add enterprise SAS-connected 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. Does this have two controllers?ExpandCollapse No. This model uses a SAS expander with redundant power supplies. Supported multipath cabling is different from a dual-controller storage system. Confirm the required host, SAS adapter, drives and path design. Which drives can I install?ExpandCollapse 12 × 3.5-inch positions supporting compatible 3.5-inch SAS 12Gb/s or 6Gb/s HDDs, 3.5-inch SATA 6Gb/s or 3Gb/s HDDs, and 2.5-inch SATA SSDs. 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 4.5.1 or QuTS hero h4.5.1 or later and built-in SAS or a supported QXP SAS card. Current listed cards include QXP-1630S-3816 and QXP-830S-3808; exact host compatibility remains required. QNAP describes up to 16 shelves for a qualified single-path topology; multipath and link aggregation reduce the chain count. Actual limit depends on host, current SAS card, firmware and cable layout. What is included, and do I need rack rails?ExpandCollapse Enclosure, 2 power cords, tray key, 1 × 0.5m SFF-8644 Mini-SAS HD cable, drive mounting screws and Quick Installation Guide. Host SAS card, drives and rails are separate. Optional RAIL-B02 or RAIL-S02, subject to rack-post spacing. 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. 続きを読む
