► Controller-based software: – Storage subsystem controller firmware and NVSRAM are always installed as a pair and provide the “brains” of the DS5000 storage subsystem. – Storage subsystem Environmental Service Modules (ESM) firmware controls the interface between the controller and the drives. Storage subsystem drive firmware is the software that tells the specific drive types how to perform and behave on the back-end FC loops. 2.3.2 Installation of the Storage Manager We first install the IBM System Storage DS Storage Manager software for managing the DS5000 storage subsystem. Testing: For the testing, we use Storage Manager SMIA-WSX64-10.70.35.25.exe downloaded from IBM Fix Central at http://www-933.ibm.com/support/fixcentral/. We are running the Storage Manager on a Microsoft Windows 2007 machine. We also cover the changes needed in the IBM System Storage DS Storage Manager to run on a workstation. Here we only show the panels in which you need to make changes, and the “splash” panel. The complete installation procedure can be found in IBM Midrange System Storage Hardware Guide, SG24-7676. Here we outline the procedure: 1. Figure 2-1 shows the first panel after the installer is launched.
