storage can be particularly beneficial for large-scale businesses when dealing with many physical

hard disks involving complex setup.

GPT versus MBR

GUID Partition Table (GPT) is the next generation of a hard disk partitioning scheme developed to lift

restrictions of the old MBR. Being a part of the Extensible Firmware Interface (EFI) standard proposed

by Intel to replace the outdated PC BIOS, it offers a number of crucial benefits:

• Up to 128 primary partitions for the Windows implementation (only 4 in MBR);

• The maximum allowed partition size is 18 exabytes (only 2 terabytes in MBR);

• More reliable thanks to replication and cyclic redundancy check (CRC) protection of the

partition table;

• A well defined and fully self-identifying partition format (data critical to the platform operation

is located in partitions, but not in un-partitioned or hidden sectors as this is the case with MBR).

Apple Boot Camp

Boot Camp is a special utility to help you set up a dual boot system (Mac OS X and 32-bit Windows

XP/Vista) on Intel-based Macs. It enables to securely re-partition your hard disk (resize an existing

HFS+ partition to create a separate partition for Windows) and then launch the installation process.

With Boot Camp all the necessary drivers will be at your disposal. Moreover after Windows has been

installed it will serve as a boot manager to choose what operating system to start up.

It is strongly recommended not to modify the hard disk configuration with

Windows Disk Manager. Otherwise it may lead to unexpected consequences,

right up to BSOD and inability to boot in Windows XP/Vista. Please use our

program to correctly update both MBR and GPT.

64-bit Support

The bulk of software today is written for a 32-bit processor. It can meet the requirements of almost

any end user. However that is not the case when dealing with servers processing large amounts of

data with complex calculations of very large numbers. That is where 64-bit architecture comes into

play.

It can boast improved scalability for business applications that enables to support more customer

databases and more simultaneous users on each server. Besides a 64-bit kernel can access more

system resources, such as memory allocation per user. A 64-bit processor can handle over 4 billion

times more memory addresses than a 32-bit processor. With these resources, even a very large

database can be cached in memory.

Although many business applications run without problems on 32-bit systems, others have grown so

complex that they use up the 4 GB memory limitation of a 32-bit address space. With this large

amount of data, fewer memory resources are available to meet memory needs. On a 64-bit server,

most queries are able to perform in the buffers available to the database.

Some 32-bit applications make the transition to the 64-bit environment seamlessly others do not. For

instance, system-level utilities and programs that provide direct hardware access are likely to fail. Our

program offers a full-fledged support of the 64-bit architecture providing fault-tolerant work for such

system dependent modules as Hot Processing.
