The QNAP CAB-SAS05M-8644-8088 is a 0.5-meter Mini-SAS cable running SFF-8644 (host side) to SFF-8088 (target side) at SAS 12Gbps. At half a meter, it is purpose-built for short-reach connections inside a rack — typically linking a head unit to a directly adjacent expansion enclosure where cable management space is tight and every unnecessary inch of slack creates airflow and routing problems. If you are wiring an ES-series all-flash or hybrid array to its expansion shelf, or connecting a SAS HBA card port to a REXP unit in the same rack unit grouping, this is the correct length to reach without looping excess cable.
Verified compatible with the following QNAP platforms: REXP-1220U-RP, REXP-1620U-RP, SAS-12G2E HBA, ES1640dc v2, EJ1600, and the ES2486dc — QNAP's dual-controller enterprise ZFS NAS. The SFF-8644 connector is the external Mini-SAS HD port found on these QNAP host controllers and NAS head units; the SFF-8088 connector mates with the external SAS ports on the REXP expansion shelves. Confirm your specific head unit and expansion model both match these connector types before ordering — swapping SFF-8644 and SFF-8088 requires a different cable configuration entirely. For longer rack runs or mid-row configurations, QNAP's 1.0-meter variant (CAB-SAS10M-8088) covers greater distance on the same connector standard.
The 0.5-meter length assumes the expansion enclosure is in the immediately adjacent rack unit or within the same rack section as the host. Route the cable clear of drive bay ventilation paths — SAS cables in dense 2U/4U configurations can obstruct airflow if bundled across the front-to-rear cooling channel. Seat both connectors fully until the locking tab engages; a partially seated SFF-8644 connector is a common cause of intermittent SAS link errors at 12Gbps. No tools required for installation.
