    LANDESK Architecture

     

    There are several distinct services or functionalities that may be required or used with LANDESK Management Suite (LDMS). These can include some or all of the following:

    • LANDESK Core Server
      • This server includes IIS which provides many key web services
    • Database Server (MS SQL)
    • LANDESK Cloud Services Appliance (CSA)
    • Remote Management Console
    • Preferred Servers
    • PXE Representatives

    There are other services or servers that can be used depending on the requirements, such as a Terminal Server to allow access to the Remote Management Console or a dedicated reporting server for custom reports and so forth.

     

    Considerations for Upgrade and Install

     

    When upgrading or installing LANDESK, the demands on the system may be higher than during normal use. This can be due to increased activity that can occur during an upgrade. For example, installing a new agent may cause that device to perform several scans to ensure it is up-to-date. Additionally adoption of new features can lead to increased load on the system, so an environment that was meeting expectations before, may begin to not meet expectations as the demand or feature adoption increases.

     

    Software Requirements

    Core Server

    The LANDESK Management Suite Core Server is now fully 64-bit, so it cannot be run on any 32-bit systems.

    • Microsoft Windows Server 2008 R2 with Service Pack 1, 64-bit (Supported for in-place upgrades only)
    • Microsoft Windows Server 2012 R2 with Update 1, 64-bit

    The install language of the Microsoft Windows Server should match the LANDESK install language and the language of all Remote Consoles.

     

    Important: Upgrading the Core Server Operating System over an existing Windows installation is not supported. A "clean" installation is required

     

     

    Database Server

     

    The following database systems are supported:

    Microsoft SQL Server
    • Microsoft SQL Server 2008 Express (Free to use, but limited)
    • Microsoft SQL Server 2008 Standard/Enterprise
    • Microsoft SQL Server 2012 Express (Free to use, but limited)
    • Microsoft SQL Server 2012 Standard/Enterprise
    • Microsoft SQL Server 2014 Standard/Enterprise

     

    Important Note: Microsoft SQL Express editions are severly limited in CPU usage, memory usage and total database size. This can cause performance problems and even complete failure if those limits are exceeded. It should only be used in very small environments or test labs.

     

     

    Oracle 11g

    Oracle is not a supported database server for LDMS 2016

     

    Remote Console

    The LANDESK Managment Console is installed as part of the Core Server installation. Additional Remote Consoles can be installed as well to provide access to the LANDESK Management Suite/Security Suite tools and features. For LANDESK Management Suite 2016, the Remote Console can only be installed and run on 64-bit systems.

    Supported Operating Systems:

     

    • Windows 7 Professional, Business, Enterprise and Ultimate Editions x64
    • Windows 8 Enterprise x64
    • Windows 8.1 x64
    • Windows 10 x64
    • Windows Server 2008 R2 SP1
    • Windows Server 2012 x64
    • Windows Server 2012 R2 x64

    Hardware Recommendations

     

    Generic Guidelines

     

    The following are some generic guidelines to get started. More details based on environment size listed below.

     

    ProcessorsMemoryStorageNIC
    • Processors should include HyperThreading or similar technology
    • All processors counts below assume the processors have HyperThreading or similar technology
    • Recommend 1 - 2MB per managed device on the database. 10k nodes would mean 10 - 20GB RAM
    • Core Server should have 4 - 8 GB. More depending on use or configuration
    • For optimal performance, the Database server should have enough memory (RAM) to cache the LANDESK database in memory.
    • On-box storage is recommended for optimal performance
    • Use RAID arrays for redundance and speed on both Core and Database
    • Make sure there are enough disks in the array
    • LANDESK recommends that there be physical separation of the database array when using shared storage
    • Any storage technology should be able to deliver 300 - 500 KBPS burstable per 1000 nodes
      • Example: 8k nodes should have 2400 - 4000 KBPS burstable
    • Disk I/O is the top bottleneck for database performance when using LANDESK, so optimization of disk I/O is highly recommended.
    • Recommend 2 - 5MB per managed device on the database. When fully utilizing Data Analytics and other features, usage can climb to 10MB or more per node
    • The Core Server should only have a single IP address
    • Multiple NICs are only supported when configured with a single IP address.
    • Gigabit or better NICs recommended

     

    Additional Guidelines by Environment Size

     

    Up to 750 Devices

    All LANDESK Services on a single server
    • Dual-core, 64-bit processor
    • 4GB RAM
    • 100/1000 Mb Network Adapter
    • 72 GB of free disk space on 10K RPM or faster drives or arrays.
      • Drive/Array configuration
        • One drive or array for the operating system, LANDESK Management Suite application, and database application
        • One drive or array for the database and database logs

     

    750 to 1,500 Devices

    All LANDESK Services on a single server
    • Quad-core, 64-bit processor. (Preferably two physical quad-core processors)
    • 4+ GB RAM
    • 100/1000 Mb Network Adapter
    • 72 GB of free disk space on 10K RPM of faster drives or arrays
      • Drive/Array configuration
        • One drive or array for the operating system, LANDESK Management Suite application, and database application.
    • One drive or array for the database and database logs. RAID 0, 5, 10, or an equivalent/faster redundant storage technology is recommended.

     

    1,500 - 3,000 Devices

    All LANDESK Services on a single server
    • Two Quad-core, 64-bit processors (8 CPU cores total)
    • 8 - 12+ GB of RAM or more
    • Gigabit network adapter
    • 3 storage arrays with 72 GB of free space each on 15K or faster drives
      • One array for the Operating System. RAID 0, 1, 5 or faster
      • One array for LANDESK Management Suite software. RAID 0, 5, 10 or an equivalent/faster technology
      • One array for the database and database logs. RAID 0, 5, 10 or an equivalent/faster redundant storage technology

    A LANDESK system for 1,500 to 3,000 devices all running on a single server could see performance issues with disk I/O depending on the use and configuration of both LANDESK and the storage arrays. Some tuning may be needed. As noted above, the arrays should be on separate spindles (physical disk) to reduce any resource conflicts.
