Ultra Streaming Data Path optimizes performance by enabling a new transfer to begin on the bus before the active transfer has finished. Adaptec’s Seamless Streaming Technology features Adaptec-designed, dedicated hardware engines that automatically handle the packet protocol. Adaptec’s innovative Seamless Streaming Technology boasts advances that allow enterprise servers and workstations to achieve the full performance potential of Ultra SCSI data throughput. Adaptec’s AIC with Ultra Streaming Data Path virtually eliminates the overhead associated with establishing a solid SCSI connection, enabling the bus to take full advantage of packet protocols and deliver its maximum throughput speed. In an Ultra SCSI bus, for each new command the SCSI connection must be completely closed, then re-established, the command retrieved, then sent, and the entire process repeated for each command.

Adaptec’s Seamless Streaming Technology gives users a performance edge xic Ultra SCSI by innovatively exploiting the full performance potential of the standard’s specification to deliver the theoretical maximum data throughput speed. Plus, command and status phases are accomplished in relatively slow asynchronous mode, and are limited to a single transfer per connection.

It also eliminates latencies in the disconnection, bus free, arbitration, and reselection phases.

This proprietary queuing arrangement enables the streaming delivery of all the commands for a specific target. Ultra SCSI packetizes commands, data, ac status information, and transfers them at synchronous speeds. This allows commands to be streamed to both buses, allowing each to operate at peak efficiency to deliver full Ultra speeds. 77902b it is possible to initiate a new context on the bus immediately after the previous context – if the data path allows.

Adaptec’s new Seamless Streaming Technology pushes the performance of Ultra SCSI to its theoretical limit by implementing in hardware three key new design advances:.

This improves performance by maximizing bus utilization and minimizing command overhead because multiple commands can be transferred in a single connection and at higher speeds.

As SCSI generations have advanced in speed and capability, new design solutions have had to be devised to extract the highest 7902h real-world performance out of the industry standard specification. Ultra SCSI eliminates these latencies. Such streaming performance has not been possible before. However, in order to realize the complete MB data transfer speed, packetization must be carried out as efficiently as possible.

At Ultra SCSI data transfer speeds, any software intervention to perform command management would reduce overall throughput. Because the Ultra SCSI bus could only handle a single command per connection, there was plenty of time to retrieve individual commands. Adaptec’s xic Seamless Streaming Technology boasts advances that allow enterprise servers and workstations to achieve the full performance potential of Ultra SCSI data throughput. Adaptec’s AIC with Ultra Streaming Data Path virtually eliminates the overhead associated with establishing a solid SCSI connection, enabling the bus to take full advantage of packet protocols and deliver its maximum throughput speed.

With Ultra SCSI, for instance, a new transfer cannot begin until an active transfer is complete, requiring multiple steps.

Ultra Streaming Data Auc optimizes performance by enabling a new transfer to begin on the bus before the active transfer has finished. However, there have always been certain latencies associated with the overhead tasks of managing the data path from one bus to another.

In an Ultra SCSI bus, for each new command the SCSI connection must be completely closed, then re-established, the command retrieved, then sent, and the entire process repeated for each command.

The also sports two external very high-density connector interfaces VHDCI and one internal high-density pin connector to provide users with a wide variety of connection options. Adaptec’s RPP sends commands to a target, receives status packets from a target, and transfers data to and from a target – all at the 792b maximum speed of MB across the SCSI bus.

New command-management methods are required to realize the full performance potential of the specification since it incorporates new capabilities that require a different way of handling commands.

With RPP, Adaptec’s Seamless Streaming Technology delivers the fastest and smoothest transmission of multiple commands in a single connection. This means that commands now can aid to the bus as rapidly as bus processing will allow – if there is a mechanism for organizing and retrieving the commands quickly enough.

In order to achieve the maximum possible data qic of Ultra SCSI, Adaptec has designed a hardware engine that goes beyond the limitations of current Ultra SCSI implementations to take full advantage of the performance potential of the newest generation SCSI specification.

Command management has become a critical performance issue because each Ultra SCSI channel can accommodate up to different packetized commands in synchronous mode. Seamless Streaming Technology Products.
