Which of the following media is the BEST option to provide SAN access between an HBA and a storage device, on an 8Gb/s FC network separated by less than 60 meters (196.85 feet)?

Multimode 62.5 micron fiber (OM1) generally has limited distance reach at 8Gb/s (typically around 21m), making it unsuitable for optimal 8Gb/s FC over 60 meters.

SFP+ TwinAX is a direct-attach copper cable primarily used for Ethernet (e.g., 10GbE) and is not a standard medium for 8Gb/s Fibre Channel connections, which predominantly use fiber optics.

Multimode 50 micron fiber (OM3 or OM4) is the standard and most cost-effective choice for 8Gb/s Fibre Channel connections over distances up to 60-150 meters. It offers sufficient bandwidth for 8Gb/s FC and is widely used for short-reach SAN connections between HBAs and storage devices within a data center.

Single-mode 9 micron fiber is designed for very long distances (kilometers) and is more expensive; it is overkill and unnecessary for distances less than 60 meters in an 8Gb/s FC environment.
