Как бы расширить ограничение в 32ГБ ОЗУ в Serv2008R2standard
Установлен терминальный сервер:
Windows Server 2008R2 Standard
Установлено ОЗУ (физически):
36 ГБ
ОЗУ стало не хватать и расширил физически до 36 ГБ (и дальше возможно необходимо будет расширить).
Уперся в ограничение выпуска Standard Ограничение на 32 ГБ
Может кто знает, есть ли честные или не очень обходы данного ограничение без переустановки целиком сервера?
Кто-то может обновлялся до Enterprise? Какие подводные камни есть при обновлении?

Или на 2012 перейти — там нет ограничения в стандарте.
Спасибо за совет
надо будет на 2012 глянуть, а то не видел его еще в глаза ))))

Before embarking on the installation of Windows Server 2008 R2, it is important to first gain an understanding of the different editions available and the corresponding hardware requirements. It is also important to be aware of the upgrade options available with each edition. With this objective in mind, this chapter will focus on providing an overview of both the different Windows Server 2008 R2 editions and the recommended hardware requirements.

CPU Requirements
The first item of note for users familiar with the first version of Windows Server 2008 is that the R2 edition is only available for 64-bit systems. Whilst some editions of the original Windows Server 2008 operating system were available in 32-bit versions, this is now no longer the case for the R2 version.
Windows Server 2008 R2 Foundation Edition
The Foundation edition of Windows Server 2008 R2 is the new entry level edition and is designed specifically with the small business in mind. It is the least expensive of the various editions and lacks some of the more advanced functionality typically found in the higher end editions such as full Active Directory support and Hyper-V virtualization capabilities. In addition, the Foundation edition limits some of the included features, such as restricting the number of concurrent remote desktop services connections to 50 and is able to access a maximum of 1 processor and 8GB of RAM.
Windows Server 2008 R2 Standard Edition
<google>ADSDAQBOX_FLOW</google>
Windows Server 2008 R2 Standard is another one of Microsoft’s entry level server offerings (alongside Windows Web Server R2 2008 and Windows Server R2 2008 Foundation). As previously stated, whilst the original version of Windows Server 2008 supported both 32-bit and 64-bit versions, the R2 version supports only 64-bit processors. In terms of hardware, Standard Edition supports up to 4GB of RAM and 4 processors.
Windows Server 2008 is primarily targeted at small and mid-sized businesses (SMBs) and is ideal for providing domain, web, DNS, remote access, print, file and application services. Support for clustering, however, is notably absent from this edition.
An upgrade path to Windows Server 2008 R2 Standard is available from Windows Server 2008, Windows 2000 Server and Windows Server 2003 Standard Edition.
Windows Server 2008 R2 Enterprise Edition
Windows Server 2008 R2 Enterprise Edition provides greater functionality and scalability than the Standard Edition. As with Standard Edition both 32-bit and 64-bit versions are available. Enhancements include support for as many as 8 processors and up to 2TB of RAM.
Additional features of the Enterprise edition include support for clusters of up to 16 nodes and Active Directory Federated Services (AD FS).
Windows Server 2000, Windows 2000 Advanced Server, Windows Server 2003 Standard Edition and Windows Server 2003 Enterprise Edition may all be upgraded to Windows Server 2008 R2 Enterprise Edition.
Windows Server 2008 R2 Datacenter Edition
<google>WIN28BOX</google>
The Datacenter edition represents the top end of the Windows Server 2008 R2 product range and is targeted at mission critical enterprises requiring stability and high uptime levels.
Windows Server 2008 R2 Datacenter edition supports up to 2TB of RAM and a minimum of 8 processors up to a maximum of 64.
Upgrade paths to Windows Server 2008 R2 Datacenter Edition are available from the Datacenter editions of Windows Server 2008, Windows 2000 and 2003.
Windows Web Server 2008 R2
Windows Web Server R2 2008 is essentially a version of Windows Server 2008 R2 designed primarily for the purpose of providing web services. It includes Internet Information Services (IIS) 7.0 along with associated services such as Simple Mail Transfer Protocol (SMTP) and Telnet. It supports up to 4 processors but RAM is limited to 32GB.
As with other entry level editions, Windows Web Server 2008 R2 lacks many of the features present in other editions such as clustering, BitLocker drive encryption, multipath I/O, Windows Internet Naming Service (WINS), Removable Storage Management and SAN Management.
Windows Server 2008 R2 Features Matrix
Now that we have covered in general terms the various different editions of Windows Server 2008 R2 we can now look in a little more detail at a feature by feature comparison of the four different editions. This is outlined in the following feature matrix:
|
Feature |
Enterprise |
Datacenter |
Standard |
Itanium |
Web |
Foundation |
|---|---|---|---|---|---|---|
| Active Directory Certificate Services | Yes | Yes | Limited | No | No | Limited |
| Active Directory Domain Services | Yes | Yes | Yes | No | No | Yes |
| Active Directory Federation Services | Yes | Yes | No | No | No | No |

| Web Services (IIS) | Yes | Yes | Yes | Yes | Yes | Yes |
| Windows Deployment Services | Yes | Yes | Yes | No | No | Yes |
| Windows Server Update Services (WSUS) | Yes | Yes | Yes | No | No | Yes |
Windows Server 2008 R2 Hardware Requirements
Before investing time and resources into downloading and installing Windows Server 2008 R2, an important first step is to gain an appreciation of the hardware requirements necessary to effectively run the operating system. The following table provides an overview of Microsoft’s recommended minimum hardware requirements:
|
Category |
Minimum / Recommended Requirements |
| Processor | • Minimum: 1.4GHz (x64 processor) • Recommended: 2GHz or faster Note: For Itanium based systems an Intel Itanium 2 processor is required. |
| Memory | • Minimum: 512MB RAM • Recommended: 2GB RAM or greater • Maximum (32-bit systems): 4GB (Standard) or 64GB (Enterprise and Datacenter) • Maximum: 8GB (Foundation) 32GB (Standard) or 2TB (Enterprise, Datacenter and Itanium-Based Systems) |
| Available Disk Space | • Minimum: 10GB • Recommended: 40GB or greater Note: Systems with RAM in excess of 16GB will require greater amounts of disk space to accommodate paging, hibernation, and dump files |
| Drive | DVD-ROM drive |
| Display and Peripherals | • Super VGA or greater-resolution monitor (800×600) • Keyboard • Microsoft Mouse or compatible pointing device |
As with the specified system requirements for all Windows systems, it is best to aim for the Recommended values rather than the Minimum values to ensure acceptable levels of performance. For example, whilst it is possible to run Windows Server 2008 R2 in 512MB of RAM it is unlikely that performance levels will be optimal with such a configuration.

And how do you know that the RAM is good. At the end of the day this server must be really old and it would be best to start with a new server and new OS.

Please understand my point, previously, the server was running with 64GB RAM and OS is Windows Server 2008 R2 standard 64-bit, but suddenly what happened, the RAM got limited to 32GB. While my server is running totally standalone and also not connected with internet world. So, how is this possible the OS got update and do itself limited the RAM only up to 32GB. If it is possible that standalone OS can limit the RAM usability then why it is only 32GB, not other value like 40GB or 48GB. Please specify.

The RAM did not get limited, the server has got 64 GB RAM, as we know. It’s just that your Windows Server is only showing 32 GB memory.

HI,
I´ve been in exactly same situation, what I did was install an datacenter/entreprise license and now all the RAM was presented to the OS.
