Miles U2W [INI-A100U2W MAC]
PCI to Ultra2 SCSI Host Adapter for MacOS
The Miles U2W provides unmatched Ultra2 SCSI data transfers of up to 80 MByte/sec– that’s 16 times faster than the built-in external SCSI in every Macintosh! Extended cable lengths of up to 12 meters for Ultra2 devices illustrate its system configuration flexibility. Thoroughly tested with the most common Mac peripherals, the Miles U2W provides the speed, flexibility, and compatibility required to optimize today’s most powerful Macintosh systems.
The 32-bit PCI interface transfers data at the rate of 133 MByte/sec with a 33 MHz PCI clock. The Ultra2 SCSI interface is capable of bursting data at 80 MByte/sec on the bus. This high speed interface with its embedded I/O processor makes the Miles U2W suited for servers and professional desktops. The Miles U2W uses little or no CPU bandwidth by off-loading all the I/O tasks to the 32-bit I/O processor embedded in the controller. This results in very high system performance in I/O intensive applications such as multimedia, imaging, client server databases, intranet applications, web tools and RAID subsystems that require high availability and throughput.
While the Miles U2W is capable of keeping pace with the most demanding applications, it offers complete compatibility with your existing SCSI peripherals. You can combine SCSI-1, SCSI-2, SCSI-3 or UltraSCSI peripherals for optimum performance and value. In Ultra2 SCSI modes, the SCSI I/O pad design allows cable lengths of up to 12 meters, and in point-to-point configurations cabling can be extended up to 25 meters. This increased cable length provides greater flexibility in system configurations, especially in clustering and RAID applications.
The Miles U2W features Miles 2 SmartSCSI, a user friendly setup utility that allows configuration of individual SCSI devices and host adapter termination via the keyboard. Updates to the firmware can also be accomplished with SmartSCSI’s intuitive interface. And the field upgradeable BIOS utility makes upgrading your system fast and easy.
The Miles U2W guarantees compatibility with the latest version of Mac OS-compatible systems. The newest in a family of PCI-to-SCSI host adapters from Initio, the Miles U2W has been fully tested to deliver the utmost in reliability and performance.
