SAS Steps In

SAS Steps In Over the past several years, companies have enjoyed a wide selection of technologies within the enterprise disk array market. Serial ATA (SATA), Fibre Channel (FC), and even parallel SCSI are viable options. More recently, Serial Attached SCSI (SAS) has entered the mainstream enterprise-class storage market, and its share is growing rapidly. Gartner… Read more »

SAS 1Q04 Industry Briefing

Steve Denegri, RBC — Predicts “Serial Attached SCSI (SAS) is poised for adoption as a data transport in addition to its usage as a disk interface. In fact, with direct-attach storage (DAS) remaining a popular choice for incremental disk capacity needs, a tremendous opportunity exists for SAS in connecting these storage resources to servers. Just… Read more »

SAS Starter Kit: Mixing SAS and SATA Drives in a Single Enclosure

SAS Starter Kit: Mixing SAS and SATA Drives in a Single Enclosure Serial Attached SCSI (SAS) has begun to play a key role as the enterprise continues to move towards more optimized, cost-effective storage platforms. Overcoming many of the limitations of traditional parallel SCSI implementations, SAS solutions that offer connectivity choices and support both SAS… Read more »

SAS ATA Upper Layers

SAS ATA Upper Layers– 228 BK Covers basic ATA architecture, the ATA task file, ATA commands, Serial ATA frames, and compares ATAPI (ATA Packet Interface) vs. native SCSI.

3Gb/s SAS

The first generation, 3Gb/s SAS, replaces parallel SCSI which could no longer keep pace with industry performance and scalability demands. SAS fulfilled the storage industry’s need for faster systems with more advanced capabilities. SAS features which support faster performance include dual-port drives and wide ports, enabling full-duplex data transmission plus aggregated bandwidth. Universal connectivity is… Read more »
