Building the Storage Pool for shared data disks
We have looked at a use case using two of the storage pool entry types:
1. Boot Disks
2. Private Data Disks
In the next use case, we’ll use NPIV to make use of all three storage pool types:
1. Boot Disks
2. Private Data Disks
3. Shared Data Disks
The use case for shared data disks is important when trying to build an infrastructure service which
involves more than one server participating in a type of a cluster. Examples are an Oracle RAC
cluster, an MSCS cluster, etc. The starting point is much the same as the previous use case. The
Server administrator determines the types of servers he wishes to manage with HPIO and their storage
requirements. In addition to the boot and private data disk requirements, he will also consider the
shared data disk requirements. The characteristics for shared data disks are effectively the same as
the other storage pool entry types but the Server administrator must also consider the number of
servers that need to share a particular storage pool entry. Remember, a storage pool entry may
contain a single disk or many disks. The Server administrator should consider both the sharing limit
that is required as well as the number of disks that should be contained in the storage pool entry.
The following sketch outlines the storage pool entry creation process:
