Cable CBO BlueOptics 00NV420-BL 3m SFF-8088 to SFF-8644 6 Gbit/s

CBO BlueOptics 00NV420-BL is a 3-meter server and storage interconnect cable with an SFF-8088 connector on one end and an SFF-8644 connector on the other, supporting up to 6 Gbit/s data transfer. It is designed to provide a fixed-length, direct connection between SAS/SATA host bus adapters, controllers and external storage enclosures, offering a compact and robust alternative to modular breakout assemblies and passive adapters. The cable’s construction supports reliable point-to-point communication in data centre and server-rack environments where predictable signal integrity and mechanical stability are required.

Advantages

The cable offers a straightforward, factory-terminated connection that eliminates the need for intermediate adapters, reducing insertion points and potential points of failure. With a 3 m length it balances reach and rack-management flexibility, while the use of SFF-8088 and SFF-8644 terminations ensures compatibility with a wide range of SAS/SATA equipment. The assembly supports 6 Gbit/s signalling rates, providing compatibility with legacy and mid-generation storage controllers and devices that require SATA/SAS connectivity.

Suitable for

• Connecting SAS/SATA HBAs or controllers to external storage enclosures
• Point-to-point links between servers and JBOD/JBOS arrays
• Infrastructure cabling inside server racks and chassis with short to medium runs
• Replacing passive adapters or multi-piece assemblies for cleaner cable management

Key specifications

• Cable length: 3 m
• Connector A: SFF-8088 (external mini-SAS)
• Connector B: SFF-8644 (external mini-SAS HD)
• Supported data rate: up to 6 Gbit/s per link
• Fixed, factory-terminated cable assembly for direct connections
• Designed for SAS and SATA external connections

How to use

Identify the appropriate external ports on the host bus adapter or controller (SFF-8088) and the external storage enclosure or device (SFF-8644). Align the connectors with the corresponding receptacles and insert the cable connector firmly until it seats; ensure any retention screws or latches are engaged where applicable. Use cable routing inside the rack to avoid sharp bends and to maintain minimum bend radius; secure the cable with cable ties or management brackets to prevent strain on the connectors. Power down equipment following manufacturer guidelines if required before making or breaking external data connections.

Usage recommendations

For best long-term performance, avoid repeated hot-plug cycles and maintain clear access to connector areas to prevent dust ingress. Use the 3 m length to route the cable along controlled paths within the rack, keep within manufacturer-specified bend radius, and inspect connectors for damage before installation. Verify compatibility with controller and enclosure firmware and supported transfer rates to ensure stable operation at 6 Gbit/s.
