Solid-State Drive
A solid-state drive (SSD) is a high-performance device that stores data in solid-state
flash memory. The MPX solid-state drives contain the boot loader configuration file,
configuration file (ns.conf), licenses, and for some models, the NetScaler software and
the user data.
The NetScaler software is stored on either the SSD or the CompactFlash card. The
following MPX platforms store the NetScaler software on the SSD. The SSD is mounted
as /flash.

Replacement solid-state drives (SSDs) contain a pre-installed version of the NetScaler
software and a generic configuration file (ns.conf), but they do not contain SSL-related
certificates and keys, or custom boot settings. Configuration files and customized
settings must be restored to a replacement drive from a backup storage location at the
customer site, if available. The files to be restored might include:
w
/flash/nsconfig/ns.conf: The current configuration file.
w
/flash/nsconfig/ZebOS.conf: The ZebOS configuration file.
w
/flash/nsconfig/license: The licenses for the NetScaler features.
w
/flash/nsconfig/ssl: The SSL certificates and keys required for encrypting data to
clients or to backend servers.
w
/nsconfig/rc.netscaler: Customer-specific boot operations (optional).
