Extend NetScaler instance disk space on NetScaler SDX™
The NetScaler instance disk space extension feature allows users to extend the secondary disk space of NetScaler instances on NetScaler SDX. You can extend the secondary disk space without the need to delete and recreate the NetScaler instances. This feature is enabled whenever a NetScaler instance is edited, though it is disabled during the creation of a NetScaler instance.
This feature offers the following key benefits:
-
Allows easier upgrade of NetScaler firmware without encountering disk space limitations.
-
Offers flexibility in managing secondary disk space requirements based on the workload of the NetScaler instances.
-
Ensures smoother operations for customers with increasing storage needs.
This document provides the necessary details for administrators and users to manage NetScaler instance disk space extensions on NetScaler SDX.
