Yes, PC’s with a PCI bus on their motherboards can take advantage of Ultra 2 SCSI (LVD) drives. You need a PC Ultra 2 SCSI controller to connect the drive. The data Xfer rate of a disk drive is one important parameter in the overall storage subsystem’s performance, but the data bus (50 Mhz, 66 Mhz, 100 Mhz), carries the data from the drive to the CPU. Microprocessor clock speed , SCSI controller support of a particular drive interface, Ultra SCSI, Ultra 2 SCSI etc.

Only Ultra 2 SCSI (LVD) 8 bit drives can be connected. A fairly inexpensive drive can be used if more storage space is the only criteria.

You cannot have a differential feature, that is 12 meter cable length in PCI based Macintosh or PC’s without a PCI Ultra 2 SCSI (LVD), Low Voltage Differential Card, since Macintosh logic boards and PC mother boards do not support the Ultra 2 SCSI (LVD) feature. Earlier, support for differential drives were available only on high end workstations. Now Ultra 2 SCSI (LVD) Cards are available for Macs and PCs.

This is a tough one to answer, instead we have made a performance Matrix that gives comparative analysis of drive performance parameters and features with their prices, so that an accurate decision can be made based on performance / price comparisions.

No, Ultra 2 SCSI drives are platform independent. Most of the workstations running UNIX have a SCSI 68-Pin connector or an 80-Pin SCA connector, you can install directly, internally or externally.

The answer is definitely yes. However, exactly how you do it depends on the type of Ultra Wide host adapter you have. If it is single-ended SCSI and the LVD disk is multimode LVD, you can connect the disk directly to the host adapter. The multimode LVD interface on the disk will switch to the single-ended mode. If the Ultra Wide adapter is differential (HVD), they can still be connected, however, you will have to use a SCSI expander called an HVD to SE or an HVD to LVD Converter.

LVD, which stands for Low Voltage Differential, was introduced in the SPI-2 document of SCSI-3. It is also called Ultra 2 or Fast-40 SCSI. It uses 3 volt instead of 5 volt logic level and is not directly compatible with the "old" differential (HVD) SCSI. LVD again doubles SCSI data throughput to 40 Megatransfers/sec. Cable lengths are 12 m (40 ft). Single initiator-single target applications may use up to 25 m (82 ft) of cable.

In addition to the obvious benefits of longer maximum cable length than single-ended and a doubling of data throughput, there are a number of other benefits. LVD/MSE and single-ended offer some compatibility. The lower operating voltage of the LVD bus means lower power dissipation, so the differential drivers can be included on the LVD ASIC rather than having to mount them external to the chip. This results in smaller boards, less heat dissipation, higher reliability and lower cost.

LVD is backward compatible through the single-ended interface if it is multimode LVD. It is doubtful that anyone will build LVD devices that are not multimode. Remember that connecting a single-ended device to a LVD/MSE bus will cause the entire bus to switch to the single-ended mode with its data throughput and cable length limitations.

While not native, SAS hard drives can be used on SATA desktops and workstations by adding a host bus adapter.

Ultra ATA/66 is endorsed by all leading hard drive manufacturers including Seagate, Fujitsu, IBM, Maxtor, Quantum, Toshiba, Western-Digital, and others. The Ultra ATA/66 protocol is also endorsed by Intel with full industry support expected in 1999. Go to Top

A] If you use multiple mCam100 camera attached to one PC, adjust Maximum Allowed for each of cameras need A] Adjust color in camera screen configuration. In addition, adjust focus by turning adjusting lever located below camera lens. Picture quality may be not so good and screen may be slow in a dark place. Use camera where proper lighting is available. When mCam sends images to PC, buffering happens because of slow performance of the PC.

The purchase of a CD recorder often results in what used to be an unusual situation: a machine with two CD-ROM drives in it. This leads to a number of interesting phenomena, usually having to do with poorly-written software that can't figure out which CD-ROM drive it's supposed to use. CD-ROM drives are typically connected to a sound card via a small cable (a couple of wires twisted together, ending in small molex connectors).

Yes, a legacy ATA specification drive can coexist with an Ultra ATA/66 drive, and both devices can attain their maximum performance. However, for the Ultra ATA/66 device to attain Ultra DMA 4 mode, an Ultra ATA/66 capable cable is required. Go to Top

The BR-SCA35 only has one SCSI In and One SCSI out connector. All 5 of the drives would be able to only go through one channel.

Multimode LVD and LVD/MSE (Multimode Single-Ended) are terms for the same interface. It is an implementation of SCSI that automatically switches between the LVD and the single-ended mode. When a single-ended device is connected to a multimode LVD/MSE bus, the entire bus switches to the single-ended mode. Otherwise LVD/MSE devices operate in the LVD mode.

All Solar Converter charge controllers except for the smallest have an LVD function or an LVD driver to control an external relay. To prevent low battery voltage from destroying your battery, the unit can be used to disconnect the load from your battery when it's out of charge to prevent damaging it. Normal operation resumes once the battery has received some charge either from the PV charge controller or auxiliary charger.

Only Ultra SCSI (8 bit) drives can be connected internally or externally. Ultra SCSI 16-bit drives have to be connected via a PCI Card. Ultra SCSI (16 bit) can be used with a card but a performance gap of 40 MB/s exists since Ultra SCSI (16 bit) offers only 40 MB/s (max). Ultra 2 SCSI (LVD) is highly recommended if planning to gain maximum performance with a PCI card.

Ultra SCSI, defined in the SPI-2 document of SCSI-3 offers a maximum data throughput of 20 Mbytes/sec for Narrow (8-bit) SCSI. Ultra Wide SCSI is the 16-bit version that offers 40 Mbytes/sec data transfers. Ultra Wide single-ended SCSI has a maximum cable length of 1.5 m (5 ft) with more than 4 active IDs and 3 m (10 ft) with 4 or fewer active IDs. Ultra Wide differential SCSI has a maximum cable length of 25 m (82 ft).

The AKAI's (s2000/3000/3200XL) O.S. currently indexes not more than 510MBytes of space - and talking about space, the maximum partition dimension is 60MBytes. There is no use in buying a 2GB HD because the rest of the space will never be used under AKAI OS at the moment and you cannot even create a double partition in order to use the rest of the unindexed space for your PC because it is completely incompatible with AKAI's OS way of working.

Currently Honeywall works on IDE drives only. You can configure IDE drive from Advanced Virtual Disk options in VMware. Future version of Honeywall CDROm should support SCSI. Normally, you get an allocation resource error when VMware is not able to properly communicate with the host devices. The error can be ignored, as it doesn't stop Honeywall from booting.

It is possible to damage equipments when playing with PC vidoe hardware and workstation monitorts. If the monitor has standard video inputs, is workign properly, cable is properly constructed and everything is connected to properly grounded power outlet then the risk of damaging the graphics card is minimal. Some monitors can be damaged by sending wrong frequencies to them, so be sure that you send right frequencies to monitor.

Ultra ATA functionality was phased in about the time 2-Gbyte drives became common in new computers. All currently manufactured Seagate ATA drives support Ultra ATA. For specific drive information, please refer to our Disc Drive Encyclopedia.
