NSS provides the following enhancements and changes in OES 2018:
Salvage and Purge Support for Mac: The traditional Salvage and Purge operation can be done natively on Mac using NFARM (OES File Access Rights Management). For example, using NFARM installer for Mac, you can recover or permanently delete the files or folders that are already deleted.
NSS 64-bit ZID Support: NSS supports 64-bit IDs, which supports up to 8 trillion (8E12) ZIDs.
NCP, CIFS, and FTP supports the NSS 64-bit ZID, which allows NSS to store up to 8 trillion files in a single volume. For more information, see ReZIDing Volumes in an NSS Pool in the OES 2018 SP2: NSS File System Administration Guide for Linux.
IMPORTANT:When the NSS volume is mapped through AFP, the NSS files and folders with ZIDs greater than 32-bit are not listed because of Apple Filing Protocol (AFP) limitation. If the NSS volume is shared over AFP, we recommend not to enable the 64-bit ZID option.
nss (Enhanced): Beginning with OES 2018, the nss utility has been enhanced to support all the commands that nsscon utility supports.
For more information, see nsscon in the OES 2018 SP2: NSS File System Administration Guide for Linux.
nsscon (Enhanced): Commands are added for the following:
To update the SEV interval for eDirectory or AD.
To force the SEV update for eDirectory or AD users. Also, provided options to force the SEV update for a single eDirectory or AD user.

To support the creation of pools, the following NSS tools have been enhanced:
nssmu: Beginning with OES 2018, the nssmu utility allows you to create only NSS64 pool type.

iManager: The iManager storage plug-ins allows you to create only NSS64 pool type.
For more information, see Creating a Pool in the OES 2018 SP2: NSS File System Administration Guide for Linux.
