SAS Connectivity Card (CIOv) for IBM BladeCenter

IBM BladeCenter at-a-glance guide

The SAS Connectivity Card (CIOv) for IBM BladeCenter is an expansion card that offers the ideal way to

connect the supported BladeCenter servers to a wide variety of SAS storage devices. Built on proven 3

Gbps, full-duplex, SAS technology, the SAS Connectivity Card can connect to the IBM System Storage

DS3200 from the BladeCenter E or H chassis, and to multiple Disk Storage Modules in the BladeCenter

S. The card routes the pair of SAS channels from the blade's onboard SAS controller to SAS switches

installed in the BladeCenter chassis.

This card is installed into the CIOv slot of the supported blade server. It provides connections to SAS

modules located in bays 3 and 4 of supported BladeCenter chassis. The SAS Connectivity Card (CIOv) is

shown in Figure 1.

The adapter is based on the PCI Express bus, which can be thought of as a high-speed serial

replacement of the older technology. Its use offers many benefits, including higher speeds and the ability

to send and receive data at the same time.

When using the CIOv adapter, you can simultaneously use a CFFh adapter to enable more types of I/O to

supported blade servers such as the HS22 when installed in the IBM BladeCenter H chassis. The

innovative design of the CIOv adapter works with the CFFh adapter to support this combination.

Serial Attached SCSI (SAS) is a point-to-point architecture in which all storage devices connect directly to

a SAS port rather than sharing a common bus as traditional SCSI devices do. Point-to-point links increase

data throughput and improve the ability to locate and fix disk failures. SAS architecture solves the parallel

SCSI problems of clock skew and signal degradation at higher signaling rates.
