HP G8 vs HP G7 - Which Servers Are Better?

HP G8 servers are designed in a manner that they compliment the previous G7 servers. This means that some of the features that were in the G7 servers have been maintained while others have been improved to increase efficiency. However, different servers’ users have different needs depending on the way they utilize the servers. This means that the features incorporated in the two categories of servers can be better for some specified uses consequently making it paramount to do a HP G8 vs HP G7 comparison to determine which ones are better for different uses.

Some of the things that both the HP G8 servers and the HP G7 servers have in common is that both are meant to help customer reduce energy consumption, extend the life of the data centre and reclaim capacity amongst other uses. Their efficiency is so high that if one uses the old servers which were being used around the year 2005, the energy consumed would be nineteen million kilowatts hour per year more compared to using the G7 or G8 servers. The associated carbon monoxide emission per year would also be more by about ten tonnes. But the HP G8 servers are slightly more efficient compared to the HP G7 serves when it comes to energy saving since they are endowed with the latest technology.

The G8 servers are also able to automate every aspect of how they are used consequently making the data centre they are used on self sufficient. This means that the servers allow all the operation to run smoothly and efficiently without necessarily having a manual way of controlling them. The HP G7 servers are also equipped with features that allow them to be automated. But the automation levels of the G8 automation are higher and more sophisticated consequently making them more superior.

Another point to note while doing HP G8 vs HP G7 servers comparison is that both of them have strong sensors which have the ability to detect any problem, increase computing capacity and also save energy. But the G8 uses the new HP 3-D sea of sensors which is the first such technology to be used in the industry. This technology has the ability identify overused servers, increasing computing capacity by seventy percent per watt of energy. This is all done through automated means without manual configuration and also eliminates configuration errors. The new technology has consequently given the G8 servers an upper hand while compared to the HP G7 servers.

Another of the features that is only available on the G8 servers and not on the G7 is that the servers can be configured to order. This means that the G8 servers can be made to make a direct order which is helpful and makes their use more effective.

Both the HP G8 and the HP G7 servers have the ability to identify the exact locations of each server and server rack hence able to know precisely where to adjust in case there is a problem. Some of the common adjustments usually done include the cooling levels and servers power consequently making it safe for them to be used even for long hours. However, this ability is higher in the HP G8 servers and thus they can be considered to be superior when doing a HP G7 vs HP G8 comparison.

Sata Hard Drive - Some Problems You May Experience

Serial ATA, popularly known as SATA (Advance Technology Attachment), is a computer bus interface linking host bus adapters to devices that are responsible for the storage of large amounts of data like optical drives and hard disk drives. It offers several advantages over the older version interface, for example:

- Reduced cost due to smaller cable sizes
- Using only 7 conductors instead of 40
- Faster transfer of data via higher signal rates
- Native hot swapping
- Increased efficiency in transfer via an I/O queuing protocol (optional)

 However, below are some of the problems you may experience with a SATA hard drive.

At times when you install Windows OS on your computer that has multiple SATA or RAID disks, the disk drive numbers may not correctly correspond to the SATA channel numbers as they should. Some ATA hard drives perform very regular head overloads in Linux which greatly reduces their lifespan. This is because the inactivity timer for head unload is specially configured in an overly aggressive way through ATA APM (Advanced Power Management), a feature that is unfavorable just like other non-standard ways. 

Such aggressive configurations are very sensitive to changes in IO pattern and several drives like these unload their heads and re-load them in a short while under Linux. In Windows, certain vaccine programs that are known to run in the background and can change the IO pattern may also trigger this relentless unloading and re-loading cycle. 

When libata is used with specific TSS Tcorp TS-L623D drives, some obvious hardware issues that may arise include the user experiencing some random system freezes periodically and lasting only a few minutes. After being continuously polled by hald-addon-storage, TS-L623D firmware stops responding. Acer and Asus laptop computers are the major victims.

However, Samsung SC02 seems to remain unaffected by this problem. Some of the suggested solutions to help tackle this problem include keeping a Compact Disk in the TS-L632D drive, killing the hald-addon-storage process, or cross-flashing the TS-L632D drive firmware to the SC03 version.

There are various ways to cross-flash, however, it is a risky process which could be harmful or damaging to the hard disk and as may also void the warranty. Therefore, the user is exclusively warned to use these methods at their own risk. 

First, you may consider downloading the Samsung firmware update utility or the Samsung firmware. Running �sfdnwin -nocheck� is also another option that may be used to cross-flash. (Take note that some Seagate hard drives sold during the late 2008 may time out the FLUSH CACHE when combined with NCQ commands, a problem commonly caused by firmware bug). 

The list of some of the devices affected includes ST31500341AS, ST3640623AS, ST3320813AS, ST31000333AS, ST3640323AS and ST3320613AS models. However, when any of the above mentioned devices are detected to emit a warning message, libata, in that case, will automatically disable NCQ. Some SATA hard drives e.g. hdparm t, may also display poor performance with sequential reads with measurements reaching only between 20-90% of the total expected speed. During software RAID checks and rebuilds, similar performance issues have been noticed.

These varieties of SATA hard disk problems may affect various device models differently depending on particular hard disk model and size. The various solutions available also depend on the type of hard disk problem experienced.
