Endless design flexibility using Tri-Mode Controllers
Broadcom’s Tri-Mode SerDes Technology enables operation of NVMe,
SAS, or SATA storage devices in a single drive bay. A single controller can
operate in all three modes concurrently servicing NVMe, SAS, or SATA
drives. The controller negotiates between the speeds and protocols to
seamlessly work with any of the three types of storage devices. Tri-Mode
support provides a non-disruptive way to evolve existing data center
infrastructure. By upgrading to a Tri-Mode controller, users can expand
beyond SAS/SATA and use NVMe without major changes to other system
configurations.
