VMA System Architecture
A typical HP VMA SAN Gateway system consists of one or two HP VMA SAN Memory Gateways
(nodes), one of which is designated as the master node, the other is designated as the secondary
node.
The VMA SAN Gateways provide connectivity to the network and allow multiple servers to share
the high performance flash memory VMA arrays. VMA 3200 Series Memory Arrays provide high
capacity flash storage with RAID protection.
In a HP VMA SAN Memory Gateway redundant pair, the first Gateway added to the cluster is
designated as the Master (master node). Configurations defined in the master node are then
inherited by the node in the redundant pair. If the master node fails, the secondary node takes over
the master role, and cluster management traffic is automatically redirected to the new master node.
The vSHARE management software enables you to manage HP VMA SAN Memory Gateways and
VMA 3200 Series Memory Arrays as single system through the CLI or the Web Interface. For more
information, see CHAPTER 5, “
VMA SAN Gateway Management” on page 127.
HP VMA SAN Gateway Interfaces
There are two interfaces through which you can configure, manage, and monitor the HP VMA SAN
Gateway:
• VMA Web Interface on page 21
• Command Line Interface on page 21
VMA Web Interface
The VMA Web Interface is a Web-based graphical user interface (GUI) that you can access by
connecting to the Master HP VMA SAN Gateway (master node) a redundant gateway pair. The Web
Interface provides an intuitive interactive means to manage and monitor the HP VMA SAN
Gateway and connected VMA memory arrays. For more information, see CHAPTER 2, “
Manage,
Monitor, and Administer with the HP VMA Web Interface”
on page 23.
Command Line Interface
The Command Line Interface (CLI), allows you to perform necessary management and monitoring
tasks for the HP VMA SAN Gateway. Depending on your assigned user privileges (as described in
Managing Users on page 137), a subset of commands is available for admin-level tasks. For more
information, see APPENDIX A, “VMA SAN Gateway Command Line Interface Reference” on
page 141
