Service Center Requirements - Hosting Provider

  • Last updated on

Service Center is resource-intensive. This means production systems should be dedicated to Barracuda Managed Workplace. Sharing a server with other applications results in contention for resources, particularly memory and disk throughput, which can significantly impact the performance of all applications on the server.

Memory and disk space requirements listed in this section must be dedicated to Service Center, so additional resources are required for the server operating system and any other roles performed.

Best Practices
  • For easier scaling as you grow your usage of Barracuda Managed Workplace, it is recommended that you implement a two-server deployment.
  • To reduce the possibility of data loss, store database backups on another
  • system or device in addition to the SQL server.
  • It is not recommended to install Service Center on Exchange servers or Hyper-V hosts, as these systems are typically extremely busy, and an installation could result in resource contention.
  • Additionally, it is not recommended that you install Service Center on domain controllers, which can pose a security risk.

The storage space required for the database, database backups, and transaction logs will vary based on product usage, including the number of sites and devices monitored, monitoring configurations, and data retention settings.

Network Load Balancing

Network Load Balancer

With the implementation of multiple Application Servers, load balancing is required to balance incoming requests across all Application Servers.

Load-balancing is driven by a unique virtual IP address that is typically associated with a specific URL. The hardware servers that will be hosting the content for the virtual IP address or URL will be configured in a server farm associated with the virtual IP address.

There are a number of predictor algorithms that handle the load-balancing. The following two methods can be easily deployed:

  • Round Robin is a static load-balancing predictor in which servers receive connections on a strictly rotating basis, ignoring server weight. After a server receives a connection, it moves to the bottom of the connection queue.
  • Least Connections is a dynamic load-balancing predictor in which network traffic patterns are considered. The load-balancer determines which server has the fewest connections and then forwards the incoming service request to it.

In order to function as expected the load balancer must be configured to use the persistence method source-address affinity (also known as sticky sessions). Using this method means the load balancer creates a record in memory noting to which server the requests were made for each originating IP address. All future requests from the same originating IP address will be forwarded to the same application server. A timeout may be specified so that these records are not kept forever.

Caution

If you have installed Service Center as new websites rather than virtual directories, you will need to either provision a NLB capable of having security certificates installed on it directly, or purchase the more expensive wild card certificates, which authenticate all sub-Domains for a Domain.

The Hosted Service Center database server require the following:

  • Minimum hardware requirements as listed in the table below:
Component
Hardware Minimums
CPU
  • 2 x 2.8 GHz quad core
System Memory
  • 8 GB
Storage
  • A SAN is required to avoid controller
    bottlenecks.
    • Logical Unit 1: System, Service Center application files, SQL Master database, SQL TempDB, SCMaster.MDF, ReportServer
    • Logical Unit 2 RAID-10: (6 disks): SCData_Default.MDF, MWSessionState
    • Logical Unit 3 RAID-0 (Simple Recovery) or RAID-10 (Full Recovery): (4 disks): SCData_Default.LDF, ReportServerTempDB
Software

All the software listed in this section has passed performance testing with Barracuda Managed Workplace. While it may be possible to install on other flavors of Windows or other required applications, it is not recommended because support may be limited for any products not explicitly listed.

Installation

The following installer is required:

  • Windows Installer 4.5
Operating System

Barracuda Managed Workplace will install natively for either 32- or 64-bit versions of the server operating system. When installing on a 64-bit operating system, all required software components must be installed in 64-bit mode. The following operating systems are supported:

  • Microsoft Windows Server 2016 (Standard and Datacenter)
  • Microsoft Windows Server 2012 R2 (Essentials, Standard, Datacenter
  • Microsoft Windows Server 2012 (Essentials, Standard, Datacenter)
  • Windows Server 2008 R2 (Web, Standard, Enterprise, Datacenter)
Application Frameworks

The following application framework is required:

  • Microsoft .NET Framework 4.6.0 or higher (4.6.1 or higher is recommended)

Web Server
The following web servers are supported:

  • Microsoft Internet Information Services 7.5, 8, and 8.5
  • When using SSL with IIS 7.x, the web server must be configured to ignore client certificates. This is the default setting.
Database Server

Several versions of Microsoft SQL Server are supported, but the recommended version is Microsoft SQL Server 2016. Microsoft SQL Server 2016 provides functionality not available with other versions. For more information, see https://blogs.msdn.microsoft.com/sqlreleaseservices/sql-server-2016-service-pack-1-sp1-released/.

The following database servers are supported:

  • Microsoft SQL 2019-Supported for dedicated server configuration only. See SQL Server Configuration.
  • Microsoft SQL 2016 (Recommended)
  • Microsoft SQL 2014
  • Microsoft SQL Server 2012 with Reporting Services (Standard or Enterprise)

 

Important
  • Virtualization of SQL Server with Barracuda Managed Workplace is not supported because of performance concerns for CPU and disk performance. Barracuda Managed Workplace heavily relies on SQL Server for data loading, reporting, and high speed transactions, therefore it is recommended that you do not virtualize the SQL Server to ensure that the system is responsive, performs well, and to reduce complexity in deployment and troubleshooting. Data Centers typically encourage real hardware except where databases serve light applications such as blogs.
  • For performance and management reasons, the Service Center databases should be housed in its own database instance on a dedicated system.

Microsoft SQL Server 2016 SP2 Feature pack is installed on application servers as part of installations/upgrade

Mail Server

Barracuda Managed Workplace will work with any SMTP server. Authentication and port options are configurable.

Web Browser
  • Microsoft Internet Explorer 10 and 11
  • Google Chrome current version
  • Mozilla Firefox current version
  • Safari (Mac OS and iOS - partial)
Network Requirements

The following lists the networking requirements for Service Center:

80 TCP inbound Access to the VARAdmin, SCMessaging and SC websites over HTTP.

80 TCP outbound Access to the license server and WSUS meta data server.

443 TCP inbound Access to the VARAdmin, SCMessaging and SC websites over HTTPS.

2195 TCP outbound Access to Apple web service (gateway.push.apple.com) for mobile device management feature.

2196 TCP outbound Access to Apple web service (feedback.push.apple.com) for mobile device management feature.

Firewall exceptions for the SCMonitor.exe and SCworker.exe applications must be made on each application server to allow for communications on all TCP ports where the source IP Addresses are those of the other application servers.

Required External Sites for Barracuda Managed Workplace

The following table outlines the external sites that must be allowed by security products for Barracuda Managed Workplaceto function properly.

In addition to these sites, the URL where Service Center is installed must be accessible for communication between Onsite Manager, Device Managers, and managed devices.
