AM456-9025A HP VMA SAN Gateway Installation and Configuration Guide 47

CHAPTER 5 Block Storage Configuration

This chapter describes vSHARE, its features and functions, and the steps required

to configure the HP VMA SAN Gateway to manage block storage. The following

topics are covered:

• Understanding vSHARE on page 44

• Configuring Storage Containers on page 47

• Configuring Target Ports on page 49

• Configuring Initiator Groups on page 51

• Creating LUNs on page 53

• Exporting LUNs on page 56

Understanding vSHARE

vSHARE runs as software on a HP VMA SAN Gateway enabling host systems (for

example, database servers) to use the Fibre Channel transport protocols to access

logical units of data (LUNs) stored within HP VMA-series Arrays.

On the host system, the LUN appears as a connected SCSI disk. The host formats

and partitions the LUN. The storage system sees the contents of a LUN as a set of

blocks of arbitrary data. Administrators may use vSHARE to define rules for

controlling access to LUNs based on the containers, initiators and initiator groups,

and target ports configured within the system.

• Storage Containers: An HP VMA-series Array comprises a storage

container. Every LUN created and managed by vSHARE is created within a

storage container. You can create many LUNs within a container. However,

currently there is a one-to-one (1:1) mapping between an array and a container

(one container per array).
