The world of Information Technology comes in 64-bit era. Previously, 64-bit systems were used exclusively at large enterprises, but with the time a 64-bit computing became a reality for small and medium enterprises. Most servers are dual-processor systems, so the range of products in this review is limited to two-processor server 64-bit next-generation systems.

Computation power
64-bit processor is very effective for use in several areas. Relational databases, data analysis for business and data warehousing – instances of servers, where the transition to 64-bit platform will be especially beneficial. Often, the performance of such applications is limited by a memory capacity and 16 terabytes of RAM of 64-bit platform provides a significant expansion of memory compared with a capacity of 4 GB on 32-bit systems. All the best data on standard tests of databases TPC-C are achieved on 64-bit machines. Terminal Services is another server application that would benefit greatly from the introduction of 64-bit platform. Preliminary tests show that the transition to 64-bit platform, the number of users of Terminal Services may increase by 75%.

The main criterion when comparing the 64-bit systems is the processor. The two most common types of 64-bit processors are Itanium and x64. Itanium processor provides the highest level of performance and is preferred for scalable applications, but it is incompatible with modern 32-bit programs at the binary level. It requires specially compiled 64-bit software for Itanium. Itanium can run 32-bit programs, but only in a slower emulation mode. Although the x64 platform is clearly inferior to Itanium for scalability, x64 processors fully binary compatible with 32-bit programs and can work with both 32 – and 64-bit applications with maximum speed. There are also 64-bit processors for desktop and laptop computers.

Another important factor in assessing 64-bit systems is the maximum amount of memory. Increased storage space is a great advantage when moving to 64-bit platform. However, not all systems support the physical memory higher than 32-bit level. Allowable capacity of RAM should be at least 4 GB.

Another selection criteria
The important meaning and possibilities of expansion. You should pay attention to the number of expansion slots and their type. Typically, this is the PCI slots or PCI Extended (PCI-X). Many new systems also have high-slots PCI Express. Old PCI expansion slots are located on a 32-bit bus and operate at 33 and 66 MHz. Upgraded 64-bit PCI-X running at higher speeds – 66, 133, 266 and 533 MHz. The new PCI Express is built on a consistent architecture and configuration 1x provides bidirectional data transfer speeds up to 250 MB / sec.

You cannot lose the disc drives from the sight which are included in the basic system configuration. Currently, many manufacturers are excluded from the basic configuration for the floppy drive. However, this drive is still needed to load Windows drivers during installation. Optical devices have an important meaning. Many machines come with a drive CD-ROM, but without a DVD-ROM, and some programs are available on the media DVD.

Finally, we must pay attention to the programs included in the package. Many manufacturers offer an operating system together with packages of licenses of client access (CAL). In addition, some vendors provide proprietary management tools and a variety of programs from independent companies.

Step forward
Modern generation of 64-bit servers differs by the unparalleled level of performance and scalability. X64 systems do not cause great damage to the budget and avoid problems with application compatibility. But Itanium-based systems have a significant advantage in terms of scalability.

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

We would like to give you some general tips – today the Internet technologies give you a truly unique chance to choose exactly what you need for the best price on the market. Funny, but most of the people don’t use this opportunity. In real life it means that you must use all the tools of today to get the info that you need.

Search Google and other search engines for the topic of “update drivers free“. Visit social networks and check the accounts that are relevant to your topic. Go to the niche forums and participate in the online discussion. All this will help you to build up a true vision of this market. Thus, giving you a real chance to make a smart and nicely balanced decision.
