What is/are: New in NSS 9.7 SR4 (Release Notes)


  • Scalability improvements for quota monitoring - NetApp CDOT, HDS HNAS and EMC VNX
    It is now possible to control the number of threads NSS uses to channel events into its post-processing procedures. Previously only one thread was used to channel events. In cases where NSS was monitoring large volumes of activity this could become a bottle-neck, causing a queue of unprocessed events to build up. This in-turn would lead to increased memory consumption on the NSS server and delays in quota updating. 
  • Quota miscalculation risk removed - NetApp CDOT, HDS HNAS and EMC VNX
    Customers using SMB meta-data caching on the NSS application server in combination with NetApp Clustered Data ONTAP, HDS HNAS and EMC VNX devices have previously been exposed to a risk of possible quota usage level miscalculation or loss of real-time updating. SMB meta-data caching is intended to improve performance for CIFS clients. However, caching meta-data can cause miscalculations in NSS; it is possible for NSS to respond to an FPolicy, HNAS or CEPA change notification before the cache update process has completed - in this situation the old, cached, size of a path is returned to NSS by the CIFS server. Now, in NSS 9.7 SR4, re-scan delays can be configured per platform to ensure the cache update process is allowed to complete before NSS requests size information from the CIFS server. Contact Northern Support (support@northern.net) if you believe you may be exposed to this risk and receive assistance in configuring this feature.
