  • 問題

  • 各位前輩們好,

    公司Client約300台,Member Server約50台,

    因二台AD要升級至Windows Server 2016,

    請問AD記憶體配置多少為佳?是否有資料說明引用?

    謝謝.

    Evaluating

    The amount of RAM that a domain controller (DC) needs is actually a complex exercise for these reasons:
    • High potential for error when trying to use an existing system to gauge how much RAM is needed as LSASS will trim under memory pressure conditions, artificially deflating the need.
    • The subjective fact that an individual DC only needs to cache what is “interesting” to its clients. This means that the data that needs to be cached on a DC in a site with only an Exchange server will be very different than the data that needs to be cached on a DC that only authenticates users.
    • The labor to evaluate RAM for each DC on a case-by-case basis is prohibitive and changes as the environment changes.
      The criteria behind the recommendation will help to make informed decisions:
    • The more that can be cached in RAM, the less it is necessary to go to disk.
    • Storage is by far the slowest component of a computer. Access to data on spindle-based and SSD storage media is on the order of 1,000,000x slower than access to data in RAM.

    Thus, in order to maximize the scalability of the server, the minimum amount of RAM is the sum of the current database size, the total SYSVOL size, the operating system recommended amount, and the vendor recommendations for the agents (antivirus, monitoring, backup, and so on). Add additional amounts to accommodate growth over the lifetime of the server. This will be environmentally subjective based on estimates of database growth. However, for satellite locations with a small set of end users, these requirements can be relaxed as these sites will not need to cache as much to service most of the requests.

    Calculation Summary Example

     

    Component

    Estimated Memory (example)

    Base Operating System Recommended RAM (Windows Server 2008)

    2 GB

    LSASS internal tasks

    200 MB

    Monitoring Agent

    100 MB

    Antivirus

    100 MB

    Database (Global Catalog)

    8.5 GB are you sure ???

    Cushion for backup to run, administrators to log on without impact

    1 GB

    Total

    12 GB

     

    RECOMMENDED: 16 GB
