Green circuit board with two SFF-8087 ports and a second board with six SFF-8087 ports plus five SFF-8087-to-SATA cables

LSI

LSI SAS9211-8i 6Gbps PCIe 2.0 HBA + 03X3834 20-port expander + 5 cables

SKU CH-ET2S-BN7BQ

Adds 20 internal SAS or SATA ports through a 6 Gbps HBA and expander with five cables

  • HBA IT mode enables direct drive control with LSI SAS2008 controller
  • 6 Gbps transfer rate over SAS and SATA connections
  • PCIe 2.0 host interface fits standard expansion slots
  • 20-port expander adds six Mini-SAS SFF8087 connectors for massive drive counts
  • Five SFF8087-to-SATA cables plus one SFF8087-to-SFF8087 cable included

LSI SAS2008 HBA with 20-port expander

This bundle pairs a SAS9211-8i host bus adapter running in IT mode with a 03X3834 expander card. Together they present twenty internal Mini-SAS SFF8087 ports for connecting SAS or SATA drives. The kit includes five SFF8087-to-SATA cables and one SFF8087-to-SFF8087 cable for immediate cabling.

PCIe 2.0 link caps throughput at 6 Gbps per lane

Both cards communicate over a PCI Express 2.0 host interface, so the maximum signalling rate is 6 Gbps per lane. The expander adds six Mini-SAS connectors but does not increase the upstream bandwidth available from the HBA. Total drive performance is therefore limited by the 2.0 link rather than the individual drive interfaces.

Twenty internal ports decide if the kit fits

The expander provides twenty SFF8087 connectors, which is the single figure that determines whether this package can serve the planned drive count. Builders needing fewer ports or a newer PCIe generation will find the extra connectors and the 2.0 bottleneck unnecessary.

Questions about this item

Should I use the SAS9211-8i with 8 internal ports or the 03X3834 expander with 20 ports?

The SAS9211-8i provides 8 internal ports via two Mini-SAS SFF8087 connectors, while the 03X3834 expander adds 20 ports through six Mini-SAS SFF8087 connectors for larger drive arrays.

What does the 6Gbps rating mean when the card is installed in a PCIe 2.0 slot?

Each attached SAS or SATA drive can run at up to 6Gbps, while the PCIe 2.0 host link provides sufficient bandwidth for the SAS2008 controller to serve all connected devices.

How do the Mini-SAS SFF8087 connectors limit the cabling options?

The five included SFF8087-to-SATA cables connect drives directly, and the single SFF8087-to-SFF8087 cable links the controller to the expander, both using the Mini-SAS SFF8087 interface.
