Topic: Host adapter

 Host adapter - Wikipedia, the free encyclopedia
The host adapter bridges the physical and logical chasm that separates the SCSI bus from the host computer's internal bus.
Modern host adapters contain all the electronics and firmware required to execute SCSI transactions, and often include a BIOS that not only allows the host system to boot from a SCSI device, but also facilitates configuration of the host adapter.
The host adapter usually assumes the role of "initiator," in that it issues commands to other SCSI devices.

 Host Virtual Adapter   (Site not responding. Last check: 2007-10-19)
The host virtual adapter is a virtual Ethernet adapter that appears to your host operating system as a VMware virtual Ethernet adapter on a Windows host and as a host-only interface on a Linux host.
The host virtual adapter is used in host-only and NAT configurations.
The host virtual adapter is not connected to any external network unless you set up special software on the host computer —; a proxy server, for example — to connect the host-only adapter to the physical network adapter.

 Lt Kernal HOST ADAPTER - A Functional Overview
Technically, the Host Adapter is simply required to convert the Commodores' 8-bit data and 16-bit address bus into a format that can be then handled by a hard drive controller.
In general terms, a SCSI transaction is initiated when the host adapter selects the target device (a hard drive, for example) and sends it the CDB.
Because the 6821 is a general purpose, 16 bit adapter, it could be used equally well to drive a parallel printer or turn light bulbs on and off (with suitable circuitry).

 Lt Kernal Host Adapter - Components and Troubleshooting
The Host Adapter tricks the computer to look in the second half of the EPROM, thinking it is $8000 (Host Adapter P1, pins 1and2 either grounds or is High at pin 2 of U7 - bank switches either 32K halves of the EPROM).
Note: All of the other active components used in the Host Adapter are commonly available '74LS' series TTL integrated circuits with the exception of one 2N3904 transistor.
If the drive starts searching for data, the Host Adapter is functioning as it should and the problem may be either be a bad hard drive, corrupted LK DOS data on the drive or you selected the wrong drive to use with the Kernal (see below and the section of Hard Drives).

 Enabling, Disabling, Adding and Removing Host Virtual Adapters   (Site not responding. Last check: 2007-10-19)
When you install VMware Workstation, two network adapters are added to the configuration of your host operating system —; one that allows the host to connect to the host-only network and one that allows the host to connect to the NAT network.
If you are not using a virtual network adapter, you may wish to remove it.
The presence of virtual network adapters has a slight performance cost, because broadcast packets must go to the extra adapters.

 Host Adapter Properties
Logical Adapter Number: Corresponds to the logical adapter number of the disk drive.
Some adapters such as the Pathlight SSA adapter, will report 4 logical adapters.
Fibre channel adapters commonly report multiple logical adapters as well.

 SDC3211F; 32-Bit Fast SCSI-2 Micro Channel Host Bus Adapter
When BIOS is enabled on any card in your computer system, the system will first attempt to boot from the host adapter assigned to the 330h-333h port address (if present).
If it is set to "on" the adapter will check the parity on the SCSI bus.
If it is set to "off", the adapter will not check the parity on the SCSI bus.

 8 port external SATA host adapter and RAID
Up until now, no matter what SATA host adapter you bought, the only way to set up an 8 drive external SATA RAID set was by some non-standard routing of internal ports to the outside enclosures.
The ideal SATA host adapter for G5 owners who want to have an 8 drive external array should take only one slot and have all 8 ports external.
The Sonnet Technologies Tempo-X eSATA 8 PCI-X host adapter is a compelling product for power users wanting a speedy 6 or 8 drive external SATA array connected to their Power Mac -- and it only takes one slot.

SmartLinx networks which service only one module can be operated as RS232 busses, eliminating the requirement for a host adapter module.
All controls available via the host adapter are accessible via the RS232 network mode, but the reduced 9600 baud transfer rate will make some operations slower.
Make sure the cable is connected from the Host Adapter's port to the correct PC COM port.

 SCSI Host Adapter Performance Shootout   (Site not responding. Last check: 2007-10-19)
Although all host adapters adhere to the same specifications in theory (Ultra SCSI compliance, 20MBps signaling rate) and should therefore deliver approximately the same results, I had a feeling that this test would show some performance differences among the various adapters.
In his January article, “SCSI Host Adapter Performance Shoot-out,” Sean Daily was on to something when he expressed surprise at finding less than competitive performance from an Adaptec host adapter.
The problem was not a host adapter issue; it was a drive configuration issue.
