SKU CH-PBT9-RR0P2 MPN 488765-B21

An eight-port SAS PCIe controller delivering 2.34 Gbps transfer rates for connecting 1.5 Gbps SATA and 3 Gbps SAS storage devices

  • Transfer speed2.34 Gbit/s
  • Eight ports connect multiple SAS and SATA drives
  • 34 Gbps transfer rate moves data quickly
  • PCI Express x8 interface fits standard server slots
  • Supports 3Gb SAS and 1.5Gb SATA devices
  • Tested for integration with HP ProLiant servers

What this controller does

The HP SC08Ge is an 8-port SAS PCI Express host bus adapter that connects up to eight SAS or SATA drives through two external x4 ports. It delivers a 2.34 Gbps data transfer rate and up to 2.4 GB/s maximum bandwidth. The card fits a standard bracket and is designed for HP ProLiant servers and HP StorageWorks 2000sa modular smart arrays.

Who should use it and who should not

This adapter suits administrators expanding storage on compatible HP ProLiant systems that require external SAS connectivity at 3Gb SAS or 1.5Gb SATA speeds. It is not for installations that need internal drive connections, higher link speeds, or support for protocols other than SAS and SATA.

The spec that decides fit

The controller provides two external x4 SAS ports with a 2.34 Gbps transfer rate and supports both 3Gb SAS and 1.5Gb SATA devices. Verify that your server has a compatible PCI Express slot and that your storage enclosures use the matching external SAS connectors.

Questions about this item

What SAS data rate does the 488765-B21 support and what bandwidth does that cap at?

The controller runs at 2.34 Gbps SAS and delivers up to 2.4 GB/s maximum bandwidth.

Which bracket and slot size does the SC08Ge need to fit in a server?

It ships with a standard bracket and requires a PCIe x8 slot.

How is the card installed and what step is often missed?

Insert the card into a PCIe x8 slot, secure the bracket screw, then connect the two external x4 SAS cables; the step often missed is tightening the cable thumbscrews so the links negotiate at 3Gb SAS or 1.5Gb SATA.
