Low-profile RAID HBA with eight external ports

The HighPoint RR4522SGL is a hardware RAID controller that installs in a PCIe 2.0 x8 slot and presents two SFF-8088 mini-SAS connectors for up to eight SAS or SATA drives. It supports RAID 0, 1, 5, 6, 10, 50 and JBOD with transfer rates up to 6Gb/s per channel. The low-profile bracket is included for compact server chassis.

Suited for servers that need external drive

This card targets administrators who want hardware RAID across direct-attached or expander-linked SAS/SATA storage and who run Windows Server 2008 or later, Linux kernels 3.9.4 and later, FreeBSD 8.3 or later, or macOS 10.6 and later. It is not for systems that lack a PCIe 2.0 x8 slot or that require internal mini-SAS cabling.

Dual SFF-8088 ports for eight native channels

The controller provides two external mini-SAS ports that each carry four lanes, giving eight native 6Gb/s channels without an expander. Port-multiplier support extends SATA connectivity to twenty drives, while a SAS expander can scale the array to 128 devices.

Questions about this item

How do I verify the RR4522SGL is functioning correctly after installing it in a PCIe 2.0 x8 slot?

The card should appear in the system BIOS or OS device manager as a HighPoint RocketRAID 4522 controller with two SFF-8088 ports detected; you can then open the WebGUI or CLI to confirm each attached drive shows a healthy status and the chosen RAID 0, 1, 5, 6, 10, 50 or JBOD array is optimal.

What ships with the RR4522SGL and what must I purchase separately?

The box contains the RocketRAID 4522 controller, a low-profile bracket and a quick installation guide; SFF-8088 mini-SAS cables for the two external ports are not included and must be bought separately.

Which RR4522SGL capacity or version should I choose for eight direct-attached drives versus a larger SAS expander setup?

This single model supports up to 8 SAS or SATA drives directly, up to 20 via SATA port multipliers, or up to 128 drives when cascaded behind a SAS expander; choose it for any of those scenarios — no alternate capacity or version exists.
