Microsemi 2295000-R SmartRAID 3154-16i RAID controller 16-port 12Gb/s 4GB DDR4

Server storage controller

The Microsemi SmartRAID 3154-16i is a PCI-Express 3.0 x8 RAID adapter that provides sixteen internal SAS and SATA connections through four SFF-8643 mini-SAS HD ports. It is designed for servers and workstations that need 12 Gbps storage bandwidth and hardware RAID acceleration. The low-profile MD2 form factor fits dense chassis where full-height cards cannot be installed.

Power management cuts draw by up to thirty percent

The adapter includes adapter power management that reduces power consumption by up to thirty percent during normal operation. A tethered ASCM-35F capacitor module provides flash-backed cache protection, writing the 4 GB DDR4 cache to non-volatile memory instantly if power is lost. This design avoids battery maintenance while keeping write data safe during unexpected shutdowns.

Four mini-SAS HD connectors drive sixteen drives

Four SFF-8643 internal connectors each fan out to four SAS or SATA devices, supporting up to sixteen drives without an external expander. A low-profile vented bracket is included for installation in restricted-height slots. Mixed Mode allows RAID volumes and HBA passthrough devices to operate simultaneously on the same adapter, simplifying migrations and tiered storage layouts.
