Interest increases in Serial Attached SCSI

Low cost, high reliability and simpler deployment is fuelling interest in Serial Attached SCSI, an emerging data storage standard.

Serial Attached SCSI, the newest development in SCSI technology, is designed to provide enterprise-class performance, high reliability at low cost.

In a study of 100 IT directors by Vanson Bourne for Fujitsu, 45% of respondents said they would consider deploying Sas in their storage environments.

Respondents in organisations with up to 3,000 employees were attracted by the low set-up cost of Serial Attached SCSI. Fifty two per cent of respondents from companies with fewer than 3,000 staff said they would consider adding it to their infrastructure, but this figure dropped to 37% for respondents from businesses with more than 3,000 employees.

One of the advantages of Serial Attached SCSI is that performance improves with each drive that is added into the disc array, making it possible to configure very high-performance transaction servers at costs comparable to traditional parallel SCSI-based systems, according to Fujitsu.

Serial attached SCSI drives are compatible with existing SCSI software and operating systems. A serial attached SCSI infrastructure can also accommodate SATA devices, enabling users to mix and match the technologies, using SATA drives for non-mission- critical applications.
