What is/are: New in NSS 9.8 (Release Notes)


  • Connecting Storage Allocation (Quota) with Self-service Data Management
    Northern delivers a powerful method of allocating storage that encourages or enforces data growth control. Northern also provides a unique self-service interface that allows users and Data Stewards to effectively manage their use of the file service. Now, with the release of NSS 9.8 these two capabilities are brought together.
    • New quota notification templates that take users directly to the self-service console
      Now, instead of receiving a simple notification that action is required, users and Data Stewards can directly access the NSS Console and be shown an overview of their historical use of the file service, growth statistics, storage allocation or quota information, as well as actionable files lists (age, duplication, size, file type, etc.). Highlighting opportunities for action allows more, and more relevant action to be taken and puts data owners firmly in charge of their data.
    • Quota usage, size history, events and thresholds in the self-service console
      Ensuring users and Data Stewards understand the allocation policies that apply to the file shares they own or contribute to strengthens 'quota' as a means of encouraging data housekeeping. The need for clean-up becomes obvious when usage growth over time is displayed together with quota size. Additionally, showing when emails about quota usage were sent, and who they were sent to, allows Data Stewards to see who is (and who is not) taking the necessary action.
    • New NSS Quota Update Service and Redis database
      On a more technical note, customers who use this opportunity to augment their allocation and quota policies will see that a new service and an in memory database (Redis) are part of the installation package for the NSS 9.8 Console. The "NSS Quota Update Service" is responsible for mirroring quota settings and usage level information into the Redis database. It is also responsible for updating NSS' SQL database with quota information when specific events occur (quota thresholds reached, lock, unlock, etc.) and according to a schedule (default value = 5 minutes). Note that the installation process will include a step where service account details are entered - this is the service account that will be used for the NSS Quota Update Service. It is recommended that customers enter the same account as is currently being used for the other NSS services in the environment.
  • Text-mining reports - reviewing file content to look for specific information
    The first step in protecting sensitive and valuable data is to know where it is stored, and who is storing it. Appealing directly to the needs of the organization's security, legal and data protection functions, NSS 9.8 introduces the ability to mine files for lines or patterns of text. Being able to identify social security numbers, credit card numbers, email addresses, zip codes, etc. is a central capability for multiple critical activities including protecting the organization against malware attacks, data theft or building compliance for regulatory frameworks such as GDPR. Note that files that can be read with this capability must have text-based content and a relevant filter (usually produced by the manufacturer associated with the file type) must be present and registered on the NSS application host that is running the text mining report. Please contact your Account Manager or salesglobal@northern.net for more information about this new capability and how it can be used in your environment.
  • Collecting and displaying Extended meta-data
    Many applications go beyond the standard file meta-data set (file owner, size, creation/access/modification dates, attributes, etc.) to include extended information such as author, last author, company, revision number and total editing time. Applications such as Microsoft Office and Adobe Acrobat include multiple additional fields that can be used to better understand the nature and usefulness of files. NSS 9.8 now offers the possibility to collect and display certain types of extended meta-data in file lists and summaries. This information can be very useful for end users, enabling them to more quickly distinguish important files from ROT. It can also be a valuable aid to Data Stewards in their work to maintain an accurate picture of which data belongs to which business unit or team. Please contact your Account Manager or salesglobal@northern.net for more information about this new capability and how it can be used in your environment.
  • Performance throttling schedule for data scans
    NSS' use of resources for data gathering (scanning file-systems, cloud storage and SharePoint for report creation) can now be tuned to match patterns of resource availability. General resource use within the network and on target storage infrastructure changes during the course of a day. Peaks/troughs of user activity and processes such as back-up and periodic anti-virus scanning follow a predictable cycle. This new capability enables customers to significantly increase scanning speeds during normally quiet periods; making the most of resource availability to update their image of how the file service is being used.
  • Near-duplicate custom report
    For a number of years Northern has provided the ability to produce summaries of the level of file duplication in an environment and deliver full file lists of true duplicates. This capability is delivered by the solution making and comparing hash values of files, ensuring that files are binary duplicates. In some cases, where speed is of the essence or where 100% accuracy is not required, it may be preferable to produce an analysis at a higher level where only file sizes or file names AND sizes are compared. NSS 9.8 delivers this 'near-duplicate' reporting capability. Useful as means of getting a quick overview of levels of duplication and for locating specific file shares or sites where a more in-depth duplicate analysis should carried-out.
  • Multi-host custom reports
    More and more customers are choosing to make use of Northern's extended reporting capabilities and including additional file lists and summaries in their data management dashboards. The IT Department is using summaries that expose users attempting to disguise music files, Departmental Data Stewards are ensuring legal frameworks are followed with lists of X-Ray images or CAD files stored outside of dedicated storage infrastructures, Managers are reviewing lists of files belonging to users who recently left their teams and individual users are reviewing lists of large and old files, using these to quickly clean up their data footprint. Augmenting the standard dashboards with these additional analysis makes Data Management a much more streamlined and organizationally adapted process. Now, with the release of NSS 9.8, the process of gathering additional data can be woven directly into the standard scheduled scan; balancing load across all NSS application servers, ensuring all data is refreshed according to the same schedule and that only a single 'scan job' needs to monitored and managed.
  • Improved performance in true-duplicate reporting
    Northern's engineering team has been able to make significant advances in the speed of duplicate file analysis. This advancement specifically affects NSS' ability to produce lists of true duplicates - where the binary footprint of size-matched files are compared. Through the introduction of multi-threading in the post-processing phase of report generation (previously only the initial phase of report generation was multi-threaded) speed increases of up to 40% should be expected. It is becoming increasingly recognized that built-in de-dupe capabilities are answering SRM needs but are ignoring, possibly even masking, Data Management needs. Easily produced and frequently updated analyses of file duplication - coupled with a call to action sent out to data owners - enable organizations to more effectively meet compliance, file system complexity and value realization challenges.
  • LinkTarget, LinkType and PhysicalPath can be collected in folder list custom scans
    Continuing Northern's efforts to support the effective architecting and delivery of an efficient File Storage Service, NSS is now able to collect and display what is essentially meta-data about file system paths. Within reports that output lists of folders, NSS 9.8 is able to show the target for any paths that are links, the type of that link (symbolic link, junction point or DFS), and the physical path for both UNC and links (output as "\\server\c:\dir1\dir2"). This information can be used by infrastructure architects to design and refine the file system structure behind the file service.
  • Improved detection of recursive links in report generation
    Additional improvements have been made in NSS' ability to detect and ignore recursive links. Some customers, where recursive links are heavily used, have experienced excessive scanning and report result duplication. Northern has delivered advances in this area previously but some inefficiencies have remained. It is expected, with the changes made in NSS 9.8, that all recursive links will now be detected and ignored.
  • Possibility to add dynamic custom labels into file system analyses
    A powerful new addition to NSS' report generation engine, now customers are able to add dynamically created labels into file list reports and summaries. These 'custom columns' can be populated with simple text strings, using regular expressions or with file path string manipulation. Use cases include the ability to produce a full list of files belonging to users who have recently left the organization (account disabled or last logon time >n months), or a summary of media files whose extensions have been altered that is grouped by file owner email address or Manager. There is a wide range of applications for this new capability and it opens the door for further advances within workflow introduction and automation.
  • Additions to the NSS Toolkit
    The NSS Toolkit is a utility that offers a more user-friendly approach when working with the NSSX API to create automated scripts or to perform simple tasks without using the administrative client interface. The toolkit in NSS 9.8 introduces a number of new capabilities. One of the more prominent changes is the possibility to list all effective NSS permissions (Access Rules, Path Roles and Application Roles) for a specific user account, including those inherited through policies set on groups. The possibility to manage quota server settings through the NSS ToolKit will also be a welcome tool for NSS administrators. Please refer to KB-3150 for more information about new possibilities available.
  • New options in expressions for Path Labels
    NSS 9.8 includes new Path Label expression functions that enable customers to use dates (including conversion of the cryptic Windows 'FileTime' date format), numbers and bitwise operations in Path Label configuration. Being able to more easily work with dates enables the configuration of far more straightforward Path Labels that look at logon dates for example - creating summary analyses that show the volume of data that belongs to users who have not logged on during the past six months for example. Being able use bitwise operations makes querying Active Directory for account status (enabled/disabled) more straightforward and robust - previously it was necessary to check for account status number values, where 'disabled' can be represented by several values depending on other account properties. Please refer to KB-3140 for more information about new regular expression functions that can be used in Path Labels, and do not hesitate to contact support@northern.net for guidance in configuring your Path Labels. 
  • Use of new event filtering options in ONTAP 9
    NetApp ONTAP 9.0 introduced the possibility for Northern to reduce the number of file operations that NSS must register for, meaning improved performance and reduced load. Benefits will be most significantly seen in environments where quotas are set on specific user accounts (not 'Everyone'). Now Northern can more specifically tune communications between the NetApp infrastructure and NSS to only receive notification of changes in file ownership attributes and ignore all other attribute changes, such as date changes, etc. As file ownership changes are rare, but changes in other attributes much more common, customers using quotas on user accounts should expect significant reductions in communication traffic and subsequent load. Filtering is turned on by default in NSS 9.8 / ONTAP 9.0 environments.
  • ACTION REQUIRED FOR CLUSTER CUSTOMERS USING QUOTAS: Settings now stored in the Cluster Key
    Configuration in Microsoft Cluster environments has been improved. Previously NSS settings were stored in the Node Key, requiring that configuration is repeated on each cluster node. NSS 9.8 utilizes the central Cluster Key meaning that settings only need to be established and maintained in one place. Customers using NSS to set quota or allocation policies in Microsoft Cluster environments must take additional steps prior to and following upgrade as quota settings are not automatically migrated - all other settings are migrated. Please contact support@northern.net for further information and upgrade assistance.
