CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementMedium
A technician needs to connect a server's internal SAS host bus adapter to an external JBOD disk enclosure using a single cable capable of carrying four SAS lanes. Which connector type should the technician use?
- ARJ-45
- BSFF-8482
- CLC duplex
- DSFF-8087 (Mini-SAS)
Show answer & explanationAnswer & explanation
Correct answer: D. SFF-8087 (Mini-SAS)
SFF-8087, commonly called Mini-SAS, is a connector that bundles four SAS lanes into a single cable, making it the standard choice for connecting HBAs to SAS expanders or JBOD enclosures.
Why the other options are wrong
- A. RJ-45 is used for Ethernet networking, not SAS storage connections.
- B. SFF-8482 is a single-lane connector typically used to attach individual SAS/SATA drives.
- C. LC duplex is a fiber optic connector used for Fibre Channel or Ethernet, not SAS.
Mini-SAS (SFF-8087) Connector
A high-density SAS connector that bundles four SAS lanes into one cable, commonly used to connect HBAs/RAID controllers to backplanes or JBOD enclosures.
- SFF-8087 = internal mini-SAS, 4 lanes per cable
- SFF-8088 is the external equivalent connector
- SFF-8482 connects a single SAS/SATA drive directly
Memory trick: Mini-SAS bundles four lanes like a four-lane highway squeezed into one cable.
