Adaptec SmartRAID 3101-4i controller

The Microsemi Adaptec SmartRAID 3101-4i is a low-profile PCIe 3.0 x8 RAID adapter with one internal SFF-8643 mini-SAS HD connector. It supports up to 12Gb/s transfer rates for SAS and SATA drives and includes 1GB of DDR4 cache memory operating at 2100 MHz. The card is designed for enterprise servers requiring hardware RAID with broad operating system compatibility.

Suits RAID arrays and HBA mixes.

This adapter fits builders who need internal RAID 0, 1, 5, 6, 10 or 50 plus the ability to run RAID and HBA devices together on the same controller through Mixed Mode. The maxCache 4.0 software and Advanced Data Management features help migrate data from existing arrays. Servers that require external SAS ports or more than four internal lanes will need a different adapter or an expander.

Single internal SFF-8643 mini-SAS HD port

The sole internal connector is a single SFF-8643 mini-SAS HD port carrying four 12Gb/s lanes. Verify that your backplane or drive cage uses this exact interface and that the server provides a PCIe 3.0 x8 slot with the low-profile form factor.

商品問答

What internal connector does the 2291700-R SmartRAID 3101-4i use for its four SAS/SATA ports?

It uses a single SFF-8643 mini-SAS HD connector that carries four lanes at up to 12 Gb/s each.

What bracket and slot space does the low-profile MD2 card need?

It fits a low-profile slot and includes a vented bracket; board dimensions are 2.54" x 6.60".

How is the 1GB DDR4 cache module installed, and what step is often missed?

The cache is soldered on the board, so no module installation is required; the step often missed is enabling the cache in the BIOS/UEFI and installing the maxCache 4.0 software for write-back protection.
