All servers or virtual machines require x86_64 Linux-based operating system.
Important:CommScope strongly recommends that
the disk allocated for the operating system should be mounted at root (/) and
should not be further partitioned. If further partitioning is required, contact
your CommScope Customer Support
Representative to verify the partition map prior to implementation.
WARNING: After upgrading or
migrating to a new Linux version, server configurations may be lost or altered, which could
affect Cassandra performance. Refer to the topic, "Cassandra post-migration, upgrade
advisory: Linux version upgrade checklist," in ServAssure® NXT Design and Installation Guide,
and complete the verification tasks in that section after a Linux upgrade or
migration.
