8-Port SAS 6Gb/s RAID HBA

The LSI RocketRAID 2720SGL is an 8-port SAS 6Gb/s PCIe 2.0 x8 RAID HBA designed for servers or workstations that need hardware RAID across multiple internal drives. It connects up to eight SAS or SATA devices through two internal Mini-SAS connectors and supports RAID levels 0, 1, 5, 6, 10, 50 and JBOD.

PCIe 2.0 x8 bandwidth limit

The card operates on a PCI Express 2.0 x8 interface, which caps the host bus throughput below the combined maximum of eight 6Gb/s SAS links. In heavy multi-drive workloads the PCIe lane width can become the bottleneck before the individual drive interfaces saturate.

Verify slot width and OS version

Ensure the motherboard provides a physical and electrical PCIe x8 slot (or larger) running at Gen 2.0 or newer. Confirm the target operating system is listed in the supported matrix — Windows, Linux, FreeBSD or Mac OS X 10.7 Lion (only for RocketRAID 2722 and 2744) — and that certified Mini-SAS to 4x SATA cables are available for the drive backplane.

Questions about this item

Which RAID level should I choose for this 8-port SAS controller?

The controller supports RAID 0, 1, 5, 6, 10, 50 and JBOD; pick the level that matches your redundancy and capacity needs.

What does the 6Gb/s rating deliver in real use?

It provides up to 600MB/s transfer rate per port across the eight SAS lanes.

Does the PCIe 2.0 x8 slot limit throughput?

The PCIe 2.0 x8 interface caps total bandwidth at the bus level while each SAS port runs at 6Gb/s.
