12Gb/s SAS in Full Swing

by Chet Mercado and Rick Kutcipal For data storage OEMs, system builders and end-users looking to take full advantage of the ultra-high performance that 12Gb/s Serial Attached SCSI (SAS) brings to servers, blades and network storage arrays, 2013 was the year they began to see products rolling out. Prominent vendors introduced a variety of solutions… Read more »

SAS Goes the Distance

Author: Jeremiah Tussey, PMC Senior Applications Engineer Today’s challenging datacenter environments demand flexible switching and connection capabilities for storage scalability. SAS storage architectures allow for extensible configurations by providing incremental connectivity solutions: passive copper cables, active copper cables, and active optical cables. The fundamental basis driving these solutions is the necessity for a variety of… Read more »

SAS – a Sharable, Scalable Storage Technology

Author: Susan Bobholz, Storage Market Development Manager, Intel Does the storage industry really need another storage fabric? There have been heated debates over the use of Fibre Channel, iSCSI, even InfiniBand, as THE best fabric, that continues even today. Yet, as larger and larger SAS-based topologies are being implemented, there is discussion over using Serial… Read more »

Capitalizing on the Flexibility of SAS

By Paul Vogt, Director of Product Marketing, Adaptec The flexibility of Serial Attached SCSI (SAS) allows it to be used as a universal connectivity standard for a wide range of business needs. In addition to its role as a replacement for parallel SCSI, SAS now offers the ability to reduce the cost of servers and… Read more »

SAS Components are Ready for Prime Time

Author: Rachelle Trent, SAS Product Manager, PMC-Sierra As enterprise storage requirements rapidly increase, expanding data throughput and providing scalable storage capacity is crucial. The goal of Serial Attached SCSI (SAS) was to overcome the scalability and reliability limitations of parallel SCSI and to significantly improve the ability to add hard disk drives to a system.… Read more »

Scalability and Performance Considerations

Author: Tonya Comer, Product Marketing Manager Industry Standard Servers, HP Serial Attached SCSI (SAS) is a point-to-point disk interface that builds on the functionality of SCSI for the enterprise. Borrowing reliability and performance enhancements from Fibre Channel, SAS supports dual-port and full-duplex communication between servers and disk drives. SAS extends reliability and bandwidth opportunities by… Read more »

HP ProLiant Serial Family: Increased Performance, Flexibility and Scalability

Author: Tonya Comer, Product Marketing Manager, Industry Standard Servers, HP IT managers have traditionally had scant flexibility when choosing a data center storage solution. Their options were limited to separate systems based on parallel Advanced Technology Attachment (ATA), Small Computer Systems Interface (SCSI) or Fibre Channel disk interfaces. These storage options constrained the IT manager’s… Read more »

Scalable Storage for Server Blade Architectures

Author: Martin Czekalski, Maxtor Corporation Server blades first appeared about two years ago as a way to deliver increased server compute capabilities within a small footprint. Server blades are offered in a wide range of performance and packaging options. High-density blades (Figure 1) offer modest performance with a focus on low power and high packaging… Read more »
