The SCSI protocol
is the logical foundation for all modern storage systems, and SCSI Express provides a way of transporting SCSI over PCIe in a standardized fashion.
The Internet Engineering Task Force (IETF) has focused on IP storage networking through the iSCSI (Internet SCSI), which is developing standards for running the SCSI protocol
over TCP/IP, and through two subgroups developing standards for encapsulating Fibre Channel frames for transmission over TCP/IP.
0 in the marketplace and the development of a USB Attached SCSI Protocol
Additionally the SCSI protocol
supports multi-initiators allowing multiple servers to simultaneously address the same drive representing a true "cluster" environment.
There are also serial ATA host bus adapters that fall under the SCSI protocol
It represents a reincarnation of the long-established SCSI protocol
in a powerful form designed to meet the ever-growing performance requirements of enterprise data centers.
CATC is looking forward to supporting plugfest #3 with an expanded test suite for SAS compliance verification that should further increase vendor confidence in the market-readiness for products using Serial Attached SCSI protocol
The VSC7153 and VSC7154 deliver on the scalability supported by the Serial Attached SCSI protocol
, which we have been developing in conjunction with other key storage industry players," said Javier Izquierdo, director of Server Storage at Hewlett-Packard in Houston.
As systems were architected that moved the physical storage outside of the computer, other protocols were developed that incorporated the SCSI protocol
capabilities, but extended the physical connection distance.
This tester provides low-level testing of legal and illegal serial management protocol (SMP) and serial SCSI protocol
(SSP) frames and data patterns, out-of-band (OOB) and speed negotiation signals, and device powerup and reset sequences for verifying conformance to the SAS protocol specification.
All the major enterprise interface technologies (including iSCSI, Fibre Channel, parallel SCSI and Serial Attached SCSI) use the proven SCSI protocol
Serial SCSI Protocol
(SSP) supports full duplex connections to SAS devices.
a leading data storage solutions company, today introduced a new data storage array capable of supporting up to five heterogeneous servers sharing a storage pool via U160 SCSI protocol
, capable of scaling to 2.
I'm excited about this technology," said Stephen Schaeffer, manager of the research effort, "It brings the venerable SCSI protocol
, which is a good, solid and widely deployed protocol, and enhances it to reflect today's storage needs.
SSP is the SCSI protocol
that carries COMMAND frames (IU 06).
