NetWare Cluster Services (v. 1.01) - product upgrade license - 500 additional users

NetWare Cluster Services for NetWare is a software product that permits you to combine a number of individual network servers into a cluster, thereby providing users with virtually uninterrupted access to their critical network resources such as data, applications, server licenses, and other services. If one network server (cluster node) in the cluster happens to fail, another will automatically take over the resources and services it provided.

NWCS promises higher levels of availability than other Intel-based clustering systems: you can provide true multi-node clustering with support for up to 32 server nodes in a cluster. In addition, NWCS does not require any proprietary hardware: you can install it on off-the-shelf Intel architecture systems.
