Expanded Configuration; Creating New Eva Host Objects For The Xp12000/Xp10000/Svs200; Xp12000/Xp10000/Svs200-Eva Connections For Expanded Performance - HP StorageWorks XP12000 User Manual

different logical units (LUs) from each of the two EVA controllers at the same time. This allows an attached
host (or XP12000/XP10000/SVS200) to use both paths shown in
simultaneously.

Expanded configuration

To better realize the performance capability of an EVA being used as an external storage array, add the
connections illustrated in
one Fibre Channel path to each of the two EVA controllers through their respective Fibre Channel switches
and switch connections as described previously. This configuration allows for a greater performance
potential in that more than one XP port can drive a single active EVA port to a particular EVA LU. An
example of this configuration is illustrated in
Figure 66

Creating new EVA host objects for the XP12000/XP10000/SVS200

The EVA family of arrays organizes its LU presentations to attached hosts by defining and manipulating
host objects. Each host object consists of the following information:
• Host name
• IP address (optional)
• Operating system
• World wide port names of host HBAs
After this object is created for a given host, EVA Vdisks (virtual LUs) can be assigned to that host.
For the XP12000/XP10000/SVS200 to use LUs resident on the attached EVA, a host object must be
defined for the XP12000/XP10000/SVS200.
Use HP StorageWorks Command View EVA to create EVA host objects. Set Host name to a unique name
representing the XP12000/XP10000/SVS200, and set Port WW Name to the world wide port name of a
