Adoption of technology Serial Attached SCSI disks (SAS) for storage in the enterprise segment is predicted to be more extensive and would exceed the usage-based disk technologies Fibre Channel (FC). Indra W. Nugraha, Senior Solutions Consultant Hitachi Data Systems Indonesia said, during this large-scale enterprise (enterprise) tend to give priority to performance factors in the selection of storage technology, so they typically use FC-based disk.
In a test by the SPC on the Hitachi Adaptable Modular Storage 2500, revealed that the price-performance ratio is very low, ie EUR 6.71 per SPC-1 IOPS (Input / Output Operations per Second) – unit for measuring the speed of processing systems.
For companies, this result is claimed to show that SAS provides a high performance level required but with lower costs.
Besides able to save investment and operational costs, Indra tells SAS technology is more flexible, able to bridge the technological disk SATA (Serial ATA) which is normally used as storage beginners (entry-level) by small and medium scale businesses.
SAS itself is not a new concept or technology. The disks with SAS interfaces to the enterprise segment has been marketed since 2004, initially as a replacement drive is SCSI (Small Computer System Interface) which is slower.
Since the availability of SAS at speeds 3 Gbps and 6 Gbps, FC-based disk matching its performance. Along enhance SAS technology, analysts estimate sales increased while FC SAS increasingly declining. The vendor also limit the development of FC disks up to 600 GB with 4 Gbps interfaces.
