NLVM provides the following enhancements and changes in OES 23.4:
Micro Focus is now part of OpenText. Products across the portfolio are now rebranded to reflect OpenText or a more appropriate name. This corporate change impacts the name of products and components, user interfaces, logos, and so on. As a result of this corporate change, OES 2023 SP1 is now referred as OES 23.4.
The documentation is being updated in stages to reflect these changes, including names and screenshots. You can still come across references to Micro Focus in the documentation library until all of the manuals are updated.
Cache Devices (cachedev) are special block devices that are designed for hosting cache for the NSS storage pools. You can group the free storage space available in the fast storage devices to form the cache device. Adding partitions or more devices will allow you to expand the cache device even further. For more information, see Section 6.0, NLVM Commands and Cache Devicesin OES 23.4: NSS File System Administration Guide for Linux.
The NSS storage pools can have cache on a specific cache device in order to improve the IO performance. For more information, see Section 6.0, NLVM Commands and Cache Enabled Pools in OES 23.4: NSS File System Administration Guide for Linux.
