Spectrum Scale NSD servers

Edit online

This description applies to the NSD configuration only. Three lightweight additional Spectrum Scale NSD servers were added to the SUT for Spectrum Scale NSD.

The SAN disks for the FileNet® File Storage Area were directly attached to these three servers only. The NSD clients (ECM nodes) accessed the File Storage Area disks over the network and had no direct SAN access.
