Page 33: Service Interface
Service interface The ESS provides service interface ports for external connection of a service terminal. IBM or your service provider can perform service on the ESS by using an IBM mobile service terminal (MoST) or equivalent. Remote services support The ESS service interface also provides remote service support with call-home capability for directed maintenance for service personnel.
Page 34: Fibre-Channel Connection
500 m (1500 ft). The ESS can be up to 11 km (6.8 mi) from your host when you connect to it with an IBM SAN fibre-channel switch. The ESS can also be the same distance from your host when you connect to it with an IBM fibre-channel storage hub.
Page 35: Switched Fabric Topology
The ESS supports the switched-fabric topology with point-to-point protocol. The ESS fibre-channel adapter should be configured to operate in point-to-point mode when you connect it to point-to-point topologies or fabric topologies. See Figure 5. S008945N Legend 1 is the host system. 2 is the ESS.
Page 36: Introducing The Ibm Subsystem Device Driver
ESS. It uses redundant connections between the host server and disk storage in an ESS to provide enhanced performance and data availability. Figure 7 on page 13 is an example of the type of configuration that IBM Subsystem Device Driver supports. These connections comprise many different components through which data flows during input and output processes.
Page 37 With dual clusters and multiple host interface adapters, the ESS provides more flexibility in the number of input-output (I/O) paths that are available. When there is a failure, the IBM Subsystem Device Driver reroutes I/O operations from the failed path to the remaining paths. This function eliminates the following connections as single points of failure: a bus adapter on the host server, an external SCSI cable, a fiber-connection cable, or a host interface adapter on the ESS.
Page 38: Ibm Enterprise Storage Server Availability Features
System/390 hosts running TPF can use routines that ensure volume redundancy Redundant array of independent disks implementation The IBM Enterprise Storage Server protects all storage with redundant arrays of independent disks (RAID). An array is an ordered collection of physical devices (disk drives) that are used to define logical volumes or devices.

ESS. OS/400 operating systems When attached to an IBM AS/400 with an OS/400 operating system, the ESS can emulate a 9337. The ESS as an emulated 9337 reports differently to the AS/400 than does a real 9337. The major differences are in the AS/400 Hardware Resource Manager, some AS/400 service screens, and the AS/400 performance monitors.

Code 1121 and 1122 ship group – The service representative records the information from the old label onto the new blank label (PN 05J7400) that IBM provides in the VSS Ship group. The service representative attaches the new label to the lower right-hand corner of the 7133 drawer so that it is visible.
