Overview
The Promise F29000020000091 VTrak SATA AA-MUX Adapter is a dedicated multiplexer card designed for Promise VTrak E-series and J-series storage arrays. This pack contains four adapters—one per drive sled—and enables dual-port functionality on single-ported SATA disk drives, allowing them to operate with active-active multipathing in dual-controller configurations.
Key Features
- SATA Active-Active Multiplexing: Provides true dual-port functionality to single-ported SATA drives without performance loss
- Full Bandwidth Support: Each port maintains full 3 Gbps SATA-II bandwidth; no sharing or degradation
- Multipathing Support: Enables active-active multipathing in dual-controller VTrak arrays
- Mixed Drive Compatibility: Allows safe mixing of SATA and SAS drives in the same array
- Pack of Four: Supplies adapters for up to four drive sleds in a single order
