Low-profile SATA RAID controller

The RocketRAID 642L is a low-profile PCIe 2.0 x4 host adapter that adds four SATA 6.0Gb/s ports to a PC or Mac. Two connectors are internal and two are external eSATA, so drives can sit inside the chassis or in an external enclosure. The onboard Marvell 88SE9235 controller handles RAID 0, 1, 5, 10 and JBOD without using host CPU cycles. A port-multiplier function lets the card address up to 20 SATA devices in total.

Builders with legacy OS requirements

This card suits integrators maintaining Windows Server 2003, 2007 or 2008, Windows Vista, 7 or 8, Mac OS X 10.5 or major Linux and FreeBSD releases. It is not for builders who need driver support for current Windows Server or macOS versions, nor for systems that lack a PCIe 2.0 x4 slot. Users wanting more than four native SATA connections or hardware RAID 6 will also need a different solution.

Four native SATA 6.0Gb/s ports

The single specification that decides fit is the port count: two internal SATA and two external eSATA connectors, each running at up to 6.0Gb/s. If the build requires exactly four native 6Gb/s links and the operating system is listed in the supported matrix, the 642L matches; otherwise the port count or OS support will be the limiting factor.

Questions about this item

Will the RocketRAID 642L fit in a low-profile slot with a 2.6" by 3.1" bracket?

The card uses a low-profile form factor measuring 2.6 inches by 3.1 inches and includes a low-profile bracket in the package for direct installation.

Which driver do I load first when installing the RocketRAID 642L on Windows Server 2008, and what step is often missed?

Install the driver from the included software CD before connecting any drives; the step often missed is loading the driver during OS setup so the RAID volumes are visible immediately.

How many SATA devices can the Marvell 88SE9235 controller on the RocketRAID 642L support through port multipliers?

The Marvell 88SE9235 controller supports port multiplier expansion up to 20 SATA devices across the four 6.0Gb/s ports.
