What is/are: System Requirements

Background

There are fundamental requirements for the systems where Northern Storage Suite will be run, and the target file systems that will be managed with the solution. The different elements that are involved in an NSS deployment are described in the diagram below:

Figure 1: NSS Deployment Topology

Deployment Architecture

As shown in this diagram a key component of any NSS deployment is the NSS managing host - an installation of NSS that administers the configured policies. The number of NSS managing hosts that are required in an environment is determined by several factors:

  • The total number of directories that will be managed with quotas.
    • One 64bit NSS host with 8GB of RAM can monitor up to 8million directories.
  • The desired interval between reporting updates (how quickly should reports be generated).
    • In normal conditions NSS will scan between 500 and 1500 files per second. By multiplying the number of managing hosts and distributing scan load the total time required to generate reports is reduced (this is a linear relationship; two hosts scan in half the time of one host).
    • NIC teaming can also be used to increase scan speeds.
  • The geographical distribution of target storage devices.
    • Network latency between the NSS managing host(s) and target storage devices is a critical factor for both reporting speeds and quota monitoring activities. Latency in excess of 1 milisecond will have a pronounced affect on both operation types. It is highly advised to locate NSS managing host(s) on the same LAN as any target storage device.

In addition to the system requirements described in this document, there are a number of pre-requisites that must be in place for Northern Storage Suite to function as intended. These pre-requisites are explained in KB-1745.

Specifications

Managing Host - Preferred System

  • Windows 2012 Server R2
  • Internet Explorer 11
  • CPU: 6 core Intel Xeon 5500 or equivalent
  • RAM: 6 GB or more
  • HDD: 20 GB available
  • .NET Framework 4.5 (for NSS Console, Data Gathering API and SharePoint scanning)

Managing Host - Supported System

  • Windows Server 2008 - SP2 with Windows Update 2763674
  • Windows Server 2008 R2 - SP1 with Windows Update 2949927
  • Windows Server 2012
  • Windows Server 2012 R2
  • Internet Explorer 9-11
  • CPU: 4 or more core Intel Xeon 5500 or equivalent
  • RAM: 4 GB or more
  • HDD: 20 GB available

Remote Client Operating System
Most commonly the NSS client is run directly on the NSS server machine; administrators connect to an NSS server using remote desktop or similar and the manage all policies from that client. The client can also be run on the following desktop operating systems. Instructions for installation of remote clients is available in KB-2885.

  • Windows Vista - SP2 with Windows Update 2763674
  • Windows 7 - SP1 with Windows Update 2949927
  • Windows 8 (preferred)
  • Windows 10

DBMS
Database size is determined by the size of the environment being managed, the  automatic data-retention policies in place, and also by the way in which the software is used; the number of configured file-level reports, frequency of host scanning, etc. A useful rule of thumb is that the database will be under 0.2% of the size of the environment after 1 year of normal use with all data retained; i.e. a 100TB environment will result in a database of 200GB or less.

  • MS SQL Server 2014 (preferred)
  • MS SQL Server 2012
  • MS SQL Server 2008
  • MS SQL 2012 Express (POC/pilot deployments only)
  • MS SQL 2008 Express (POC/pilot deployments only)

In addition to this, both the database and the database server default collation has to be set to Case Insensitive. If your SQL server's default doesn't include '_CI' in the collation setting, you need to configure a new SQL instance with this setting in order to correctly create and use the NSS database tables.

LDAP
Northern Storage Suite uses a mixture of LDAP lookups and AD queries, particularly in quota operations. As such Active Directory is the required directory system.

  • Windows Server 2008 AD DS
  • Windows Server 2012 AD DS (preferred)


Target Storage Devices
NSS can manage multiple target device types. The requirements for each supported device are as follows:

  • EMC Unity/VNX/Celerra: DART 7.0.12 or later (VEPA/CEPA installation required)
  • Isilon 6.5 or later
  • HDS HNAS 12.3 or later
  • NetApp 7-Mode: Data ONTAP version 7.3 or later 
  • NetApp Clustered Data ONTAP - Single Branched Tree architecture: Data ONTAP 8.2 or later, NSS 9.5 or later
  • NeApp Clustered Data ONTAP - All architectures: Data ONTAP 8.2, NSS 9.6 or later
  • NeApp Clustered Data ONTAP - All architectures: Data ONTAP 8.3 or later, NSS 9.61 SR1 or later
  • Other IP Storage: Fully compliant with Microsoft CIFS (some NSS features not available)
  • SAN: Any SAN that is presented as a local drive to the NSS managing host (host requirements above)
  • DAS: NSS is installed locally, as such the host requirements described above apply
  • MSCS Windows 2008 (Active-Active or Active-Passive configurations, no restriction #nodes)
  • MSCS Windows 2012 (Active-Active or Active-Passive configurations, no restriction #nodes)
