Eight-port low-profile RAID controller

The Microsemi SmartRAID 3154-8i is an eight-port SAS/SATA RAID adapter in a low-profile MD2 form factor. It connects through a PCI-Express 3.0 x8 slot and delivers up to 12 Gbps per port through two internal SFF-8643 mini-SAS HD connectors. On-board 4 GB DDR4 cache at 2100 MHz is protected by a tethered ASCM-35F capacitor module that flushes data to flash on power loss. Mixed Mode allows RAID and HBA devices to operate simultaneously on the same adapter.

Server builders needing eight internal lanes

This card suits administrators adding up to eight SAS or SATA drives to a server or workstation chassis that accepts a low-profile PCIe 3.0 card. It is not suited for systems that require external drive connectivity or more than eight internal ports. Environments without a compatible low-profile slot should select a different form factor.

4 GB DDR4 cache with flash backup

The defining specification is the 4 GB DDR4 cache paired with the ASCM-35F capacitor module, which guarantees cache persistence during unexpected power loss. This combination determines whether the controller meets the data-protection requirements of the target workload.

Questions about this item

Will the SmartRAID 3154-8i work in a server that only has PCIe 3.0 slots?

Yes, the adapter uses a PCI-Express 3.0 x8 interface and is designed for low-profile MD2 slots, so it fits and runs at full 12Gb/s speed on any PCIe 3.0 backplane.

How can I verify the 4GB DDR4 cache and flash backup are active after installation?

The maxView management utility shows cache status, capacitor health, and firmware version; a healthy ASCM-35F module reports "Cache Protected" and the DDR4 cache size reads 4GB.

Does the box include the SFF-8643 cables needed to connect eight drives?

The package contains the SmartRAID 3154-8i adapter and an additional low-profile vented bracket; mini-SAS HD cables for the two SFF-8643 ports must be purchased separately.
