HP VMA-series Memory Arrays - Manual (Page 94)

94 HP VMA SAN Gateway User’s Guide AM456-9026A
• Storage Containers: A HP VMA-series Memory Array contains a storage container;
currently there is a one-to-one (1:1) mapping between an array and a container (one container
per array). Every LUN created and managed by vSHARE is created within a storage container.
You can create many LUNS within a container.
• Initiators and Initiator groups: An initiator is a host or client that requires access to the
LUNs stored in a container. Multiple initiators may be grouped together in an initiator group
(igroup). Access to the LUNs in a container can be restricted to specific initiators or initiator
groups.
• Targets: A target identifies the port on the SAN Gateway through which the initiator can
access the LUNs stored in a container. Access to the LUNs in a container can be restricted by
target port.
vSHARE System Architecture
The vSHARE architecture is optimized for rapid access to and processing of large amounts of data,
including enterprise databases, data warehouses, application servers, and cloud-scale analytics.
Note: SAN Gateways running vSHARE can be deployed in a High Availability configuration,
consisting of a pair of SAN Gateways with redundant access to a HP VMA-series Memory Array.
For information on how to configure vSHARE for High Availability, see the
Configuring a Redundant
Pair of VMA SAN Gateways - Process Guide .
A typical vSHARE cluster consists of one or more HP VMA Array running the vSHARE software
application and one or more HP VMA Arrays.
The vSHARE application allows you to manage LUN and initiator-target relationships. The SAN
Gateways operate as the SAN targets and the hosts (such as a database server or application server)
are the initiators . The SAN Gateway provides network connectivity, utilizing Fibre Channel. The
SAN Gateways and Memory Arrays are connected via PCIe cables.
