There are many connectors used in servers and data centers, among which Serial-attached SCSI (SAS) and SAS-PCI Express (SAS/PCIe) connectors are very popular. SAS connectors support higher speed and have more stability. SAS (SFF8680 and SFF8482) and SAS/PCIe (SFF8639) connectors are basically used for connecting peripheral devices to computer and larger storage servers. ATA physical storage interfaces, like SATA was the predecessor to this group. Storage connectors are especially used for access to mass storage devices, particularly external hard drives and magnetic tape drives.

SAS and SAS/PCIe connectors are actually the advanced versions of older parallel technologies and have thinner yet longer cables. As serial interfaces have fewer conductors in cables, the problems related to crosstalk are lesser compared to parallel interfaces. Apart from this, the hardware for serial interfaces are cost-effective compared to equivalents used in parallel interfaces.

Hot-plugging and blind-mating, connector misalignment compensation and a PCB retention mechanism for robust SMT attachment are some of the key features of these 29-position and 68-position receptacles and plug. SAS and SAS/PCIe connectors generally support both SAS and SATA drives. They also meet a wide range of vertical and right angle configurations and are used across different types of server and storage equipment, HDDs, HDD carriers and SSDs.

Vertical receptacles come with wide-base housing options and are available in surface mount (SMT), press-fit (Press-fit), and hybrid terminations. PCB attachment stamped clips act as connector retainers. SAS connectors supports interposer cards / paddle cards.

The varied features helps in addressing the needs of both mission critical and bulk storage applications. Apart from the usage in data centers and storage servers, these are used in Processor and Storage Blade and Mezzanine Card in communication sectors. SAS and SAS/PCIe connectors are used for industrial and instrumentation purposes in embedded system board and surveillances cameras as well.
