SATA offers a high data transfer speed with a lower cost than most parallel SCSI devices.
The standard version of the RT8000 Parallel SCSI Adapter includes a low-voltage circuit which enables it to operate reliably when drawing its power from the terminator power pin on the peripheral's SCSI connector.
Largely dictated by the limits on physical cable length, parallel SCSI storage connectivity requires close proximity to its host system, typically a server.
Requirements like these for large volume data storage, compounded by fast query requirements are stretching the processing capability of parallel SCSI technology.
SAS and SATA, with their increased connectivity permit use of volumes that are larger than with parallel SCSI, and potentially have higher random throughput performance.
Data centers have relied on the parallel SCSI bus interface as the workhorse of disk drive interconnections for almost 25 years.
Parallel SCSI ran its course from Wide Ultra to Ultra 2 and so on until Ultra 320, the latest version which transmits data at 320 megabytes per second.
Customers benefit from inexpensive iSCSI (Ethernet) technology that allows Direct Attach Storage (DAS) to become a shared storage resource solution, while overcoming distance limitations associated with traditional parallel SCSI connectivity.
As noted earlier, they require either costly bridges or deployment of their own infrastructure, separate from an enterprise's current Fibre Channel or parallel SCSI environment.
SAS is the evolutionary replacement for parallel SCSI and supports diverse applications in enterprise storage including JBODs, NAS, RAID subsystems, mid-line and near-line storage facilities, and fixed-content storage systems.
Serial Attached SCSI is a new enterprise disk interface developed as a replacement to parallel SCSI to improve storage system performance, scalability, and availability.
It is driven by technological advantages including more than quadrupling SCSI bandwidth for substantial performance gains and the ability to scale to up to 128 SAS devices on a single controller, compared with 16 for parallel SCSI.
One of the key recent changes is the migration from ATA and parallel SCSI connection technologies or the new generation of Serial ATA and Serial Attached SCSI devices.
GigaStorATX is enabling iSCSI SAN applications to replace parallel SCSI in DAS and NAS environments, and supplement/replace FC in SAN environments.
The shift from server-centric to networked storage has been dependent upon technologies designed to transfer data to and from storage repositories as fast as, or faster than, direct attached technologies, while overcoming the limitations inherent in parallel SCSI, the main interconnect for DAS.
