Microsemi SmartRAID 3154-8e 12Gb/s RAID Controller

The Microsemi SmartRAID 3154-8e is a low-profile MD2 RAID adapter that delivers eight external SAS and SATA ports over a PCI-Express 3.0 x8 interface. It provides up to 12Gb/s transfer rates and includes 4GB of DDR4 cache memory running at 2100 MHz. The card ships with a tethered ASCM-35F capacitor module for flash-backed cache protection.

Suits servers needing external JBOD

This controller fits administrators who must attach external storage enclosures through two SFF-8644 mini-SAS HD connectors while using a low-profile slot. It supports mixed RAID and HBA modes simultaneously and offers adapter power management that reduces consumption by up to 30 percent. Builders who require only internal drive connectors or a full-height bracket should consider a different model.

Two SFF-8644 external connectors for 12Gb/s SAS/SATA

The defining specification is the pair of SFF-8644 mini-SAS HD ports that enable 12Gb/s connectivity to external drive shelves. The PCI-Express 3.0 x8 host interface and 4GB DDR4 cache with flash backup complete the feature set. Verify that your chassis accepts the 2.54 by 6.60 inch low-profile form factor before purchase.

Questions sur cet article

What comes in the box with the Microsemi 2290800-R and do I need to buy cables separately?

The box contains the SmartRAID 3154-8e adapter and an additional low-profile vented bracket. External mini-SAS HD cables for the SFF-8644 ports are not included and must be purchased separately.

How do I choose between the available versions of the SmartRAID 3154-8e?

This model is a single configuration: PCIe 3.0 x8, MD2 low-profile form factor, with 4GB DDR4 cache at 2100 MHz and two SFF-8644 connectors for 12Gb/s SAS/SATA. No alternative capacity or connector versions exist for this part number.

What does the 12Gb/s transfer rate mean when the card is installed in a server?

Each of the eight external lanes can run at up to 12Gb/s, giving the adapter a combined 12Gb/s SAS/SATA bandwidth over PCIe 3.0 x8. Actual throughput depends on the attached drives, backplane and workload.
