Fibre Channel Host Bus Adapter (64-bit PCI-X card)
SCSI Host Bus Adapter (16-bit ISA card)In computer hardware, a host controller, host adapter, or host bus adapter (HBA) connects a host system (the computer) to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, Fibre Channel and eSATA devices, but devices for connecting to IDE, Ethernet, FireWire, USB and other systems may also be called host adapters. Recently, the advent of iSCSI has brought about Ethernet HBAs, which are different from Ethernet NICs in that they include hardware iSCSI-dedicated TCP Offload Engines.

[edit] SCSI
Main article: SCSI host adapter
A SCSI host adapter connects a SCSI bus to a computer. 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. Typically a device driver, linked to the operating system, controls the host adapter itself.
In a typical parallel SCSI subsystem, each device has assigned to it a unique numerical ID. As a rule, the host adapter appears as SCSI ID 7, which gives it the highest priority on the SCSI bus (priority descends as the SCSI ID descends; on a 16-bit or "wide" bus, ID 8 has the lowest priority, a feature that maintains compatibility with the priority scheme of the 8-bit or "narrow" bus).
The host adapter usually assumes the role of SCSI initiator, in that it issues commands to other SCSI devices.
A computer can contain more than one host adapter, which can greatly increase the number of SCSI devices available.
Major HBA manufacturers are HP, ATTO Technology, Adaptec, and LSI. LSI, Adaptec, and ATTO Technology currently offer PCIe SCSI adapters which fit in new Apple Mac, on Intel PCs, and low-profile motherboards from companies like HP (which now lack SCSI support due to the inclusion of SAS and/or SATA connectivity).
[edit] Fibre Channel
Today, the term host bus adapter (HBA) is most often used to refer to a Fibre Channel interface card. Fibre Channel HBAs are available for all major open systems, computer architectures, and buses, including PCI and SBus (obsolete today). Each HBA has a unique World Wide Name (WWN), which is similar to an Ethernet MAC address in that it uses an OUI assigned by the IEEE. However, WWNs are longer (8 bytes). There are two types of WWNs on a HBA; a node WWN, which is shared by all ports on a host bus adapter, and a port WWN, which is unique to each port. Major HBA manufacturers are Emulex, QLogic, LSI, and ATTO Technology.
[edit] InfiniBand
The term host channel adapter (HCA) is usually used to describe InfiniBand interface cards.
[edit] ATA
ATA host adapters are integrated into motherboards of most modern PCs. They are often improperly called disk controllers. The correct term for the component that allows a computer to talk to a peripheral bus is host adapter[citation needed]. A proper disk controller only allows a disk to talk to the same bus.
[edit] SAS and SATA
SAS or serial-attached SCSI is the current connectivity to replace the previous generation parallel-attached SCSI (PAS) devices. Ultra320 was the highest level of parallel SCSI available, SAS has extended and increased the performance of this technology.
SATA is a similar technology from the aspect of connection options. HBAs can be created using a single connector to connect both SAS and SATA devices.
Major SAS/SATA HBA manufacturers are Adaptec, HP, QLogic, LSI and ATTO Technology.
[edit] eSATA
External Serial ATA disk enclosures and drives are increasingly common in the consumer computing market, but many SATA compatible motherboards and disk controllers do not include external SATA ports. As such, adapters to connect external SATA devices to ports on an internal SATA bus are commonly available.
[edit] Mainframe I/O channels
Main article: I/O channel
In the mainframe field, the terms host adapter or host bus adapter were traditionally not used. A similar goal is achieved since 1960s with a different technique: I/O channel, or simply channel, is a separate processor that can access main memory independently, in parallel with CPU (like later DMA in personal computer field), and that executes its own I/O-dedicated programs when pointed to such by the controlling CPU.
Protocols used by I/O channels to communicate with peripheral devices include ESCON and newer FICON.

How to Upgrade a Notebook
How to Upgrade a Notebook
(Page 1 of 5 )
Many people know how to swap out their hard drives or install new memory in their desktops; you might even be able to build your own computer, but that is on the desktop platform. When it comes to notebook computers, people feel less at ease. Why is that?
It's because of the size you have to work with; everything is compacted into the size of a college text book. Another reason is that finding parts isn't as easy as for desktop counterparts. We will try to help all you nervous users with opening up your notebook computer and make upgrading it as easy as a desktop.
Before you crack open your computer, you need to figure out what is inside and what you want to upgrade. Compatibility is far worse for notebooks when compared to desktops. With desktops you can pretty much use any part you want and it will work, but with notebooks it's not that easy. It's better to first figure out what you have in it now, and what you wish to upgrade.
Upgrading the whole "guts" of a notebook is nearly impossible since each model differs in size and space. Some parts are going to be compatible across the board, but many will not. While it is best to buy directly from the manufacturer, this will more than likely result in a higher price tag than what you could buy at a third party web site.
CPU
CPUs aren't as tricky as you may think. A notebook CPU is very similar to its desktop counterpart. Mobile CPUs tend to clock slower, use a lot less power and put out less heat. The only thing to really worry about is to make sure it is supported by the chipset, and that a BIOS is available for it.
If the manufacturer sells the same model notebook with a higher CPU, it will more than likely work without problems. I would like to point out one thing as you pick out your new CPU: Pentium 4 Mobile is not the same as the Pentium Mobile! This will certainly not work no matter what you try, so don't try it.
Finding mobile processors will be harder than finding desktop CPUs. You can check out your local computer store, online retail stores or even eBay. From my experience online and brick and mortar stores will charge you insane prices for a processor. The best place to check is eBay; stick with very reputable users. I have seen CPUs that sell in stores for $200 go for as little as $40.
Memory
Picking out memory is fairly easy. All you need to do is check to see whether you need DDR or DDR2, as you would for a desktop, right? Well, yes, except you're looking for SO-DIMM memory. Both DDR and DDR2 use SO-DIMM, so picking out the notebook from the desktop shouldn't be that hard. This memory is competitively priced at online stores such as Newegg.
Today we will take a look at the Gateway 6000 series. The specific notebook model we'll use for our demonstration is the 6020GZ. It contains 512 MB RAM and a Celeron CPU. While this is usable, it isn't going to be very fast, and our goal today is to speed this fellow up some.
An important step you should take first is to see if there are any BIOS updates for your computer. Check your manufacturer's site for details. If you are installing a new CPU, the update may be required for the BIOS to work with the new CPU. If you realize this after the upgrade, you will need to reinstall the old CPU, flash it, and then redo everything. While looking at the Gateway site, I noticed that they have provided a useful PDF of many upgrades for this computer with pictures. This how-to will go over some that aren't given in the document.
The good thing about this computer is that it is very simple to get into. Other notebooks won't be so easy. I suggest reading the user's manual and any other documents on the manufacturer's site about the guts of the computer first
How to Upgrade a Notebook - Changing the Memory
(Page 3 of 5 )
The first thing you should do before touching your computer regardless of make of model is shut it down, unplug the power cord and remove the battery. Also, don't forget to ground yourself; one static shock to your computer could fry it beyond reasonable repair. Doing these few simple steps will make this upgrade successful and safe.
On my Dell Inspiron 6000, you need to practically take the whole computer apart to get to the guts of it. With the Gateway 6000 series, I only need to remove the bottom cover. There are a few screws that are holding the cover in place. Simply unscrewing them and removing the cover will expose the main parts of the computer. I have to give Gateway props for making this so easy. After you open it up you will see the big copper cooler and fan. To the right of these are the memory slots.
This one came with one 512 MB stick of memory, which left one slot unused. All you need to do is insert the other stick into the slot, make sure it is in, and then push it down until it pops or locks. This is fairly standard for all memory in most notebooks. Think of the pushing it down as using the clamps on a desktop board; it just helps to hold the memory in.
How to Upgrade a Notebook - Changing the CPU
(Page 4 of 5 )
The next step is to pop a Pentium Mobile into this computer. First we need to remove the copper heatsink and fan. There are three screws holding it down. Unscrew these screws to access the CPU and graphics card. It is easier to unscrew all all at once as opposed to one at a time; it helps relieve the pressure from the components more slowly and evenly. It also helps you avoid putting force on a certain side of the cores, which may cause them to break.
After you remove the heatsink, unplug the fan wires from the motherboard. If you yank them out and break the fan power socket, it is going to be either a long night at your house or a costly trip to the repair store.
Popping the CPU out is fairly easy. You need a screwdriver and a little twist of the socket screw. This should allow the CPU to pop right up and be easily removed. Then it's an easy matter to pop the new CPU right in. After you have it in securely, the only thing left is to put it all back together. There is however one important thing you need to do first.
This part will drastically reduce the heat problems many notebooks face. Conversely, this may also explain why your computer's fan might be on all the time or how loud it gets. Many manufacturers use some rather crappy thermal pastes. Gateway is no different.
I removed what they call thermal paste from the Intel chipset/GPU, which was some stick pad (I don't know how great it is, but it clearly wasn't helping any) and anything left on the copper cooler. I used some rubbing alcohol and a razor blade on the copper cooler. Be careful not to scratch up the bottom of the copper cooler. I used Arctic Silver, which can be found for roughly $5- $8 online. This is one of the better thermal pastes out there. I applied a small coat to both cores, and then put the cooler back on. Again, I was very careful to slowly tighten both screws so not to apply too much pressure on one side at a time.
After all is well, you should remove it again and take off the cooler. This time make sure that the copper cooler has the dark silver imprint of the cores on it. If not, you should reapply the thermal paste and make sure it is seated correctly, maximizing the surface area to which the heat is transferred. If it isn't making complete contact, you are going to be trying to cool the core with only ½ of it being able to transfer heat. This is going to cause overheating or even kill the CPU!! When you're finished don't forget to plug the fan back into the motherboard. This is often forgotten and not good for the computer.
If everything is good at this point, you're basically done. You just have to put all the screws and covers back in. Make sure you don't have any thermal paste outside the cores. Also check to see that nothing is loose and that anything that doesn't belong is gone. After you've checked carefully, screw the cover back on. Now plug in the battery and power cord and you are ready to go!
I hope this little how-to has helped you understand that upgrading a notebook yourself isn't out to the question. While it will require more attention to detail, it is no different in principle than a desktop PC. As always take your time, be careful and it will turn out fine. Doing the few upgrades listed here has turned this run of the mill PC into a machine that is up to multitasking -- it runs cooler, too.
