VMA vSHARE Architecture

A VMA SAN Gateway system is built for performance and high Reliability, Availability and Serviceability (RAS). The system fits with standard 19-inch racks in hot/cold aisles and can coexist with other data infrastructure without special facilities. A system is built with the following primary components:

• HP VMA Array: Up to 4 HP VMA Arrays can be configured in each cluster. The VMAs

contain up to 10TB of raw flash memory per array and 30TB of usable space. Unlike many other arrays, the flash memory is RAID protected and hot-swappable to ensure maximum uptime and very low data loss probabilities.

• VMA Intelligent Memory Modules (also known as VIMMs): The memory modules reside

within the HP VMA-series Memory Arrays and provide the flash memory and controllers required for high performance flash storage. These modules are hot-swappable with minimal impact on performance.

• HP VMA SAN Gateways: Each HP VMA SAN Gateway provides network connectivity

processing—typically 4 x 8Gb/s Fibre Channel (FC) and DRAM to support the vSHARE software function. Up to 2 gateways can be included in a single vSHARE system.

• HP Gateway Management Software: Management of multiple gateways with automatic

failover of virtual IP (VIP) addresses, Fibre Channel paths and management software are provided on HP VMA SAN Gateways and VMA Memory Arrays to enable the systems to be configured and monitored as a single system. SNMP and call-home email alerts are sent in the event of hardware failures or other critical events.

• vSHARE: The vSHARE VMA SAN Gateway software provides block storage functionality

deployed on HP VMA SAN Gateways. This software implements target mode functionality for Fibre Channel.

The internal architecture of the vSHARE software is designed for minimum latency , and extremely high IOPs. Use of multiple I/O paths with the HP VMA SAN Gateway and the VMA improves availability. This Intelligent Flash Storage architecture eliminates the software required for cache control, RAID control and flash memory control. It replaces them with flash memory optimized architectures that provide data protection and high performance. Latency is reduced by implementing many of the data path functions in hardware.

A VMA system typically consists of one or more HP VMA SAN Gateways running the vSHARE software and one or more HP VMA Arrays.

In this environment, the HP VMA SAN Gateways are targets, and the hosts (for example, a database server or application server) are the initiators. The storage systems have storage target devices, LUNs, which the hosts access through the HP VMA SAN Gateways. The LUNs are part of large storage arrays and they can be allocated and provisioned as needed.

AM456-9026A HP VMA SAN Gateway User’s Guide 19

vSHARE Feature Summary

vSHARE (VMA gateway software) manages SAN block storage on the HP VMA SAN Gateway, providing high performance processing, high bandwidth DRAM, and hig h bandwidth access to HP VMA Arrays.

Each HP VMA SAN Gateway operates as a SAN (Fibre Channel) target and provides access to LUNs that are stored on its attached VMA memory arrays. The LUN management capability of vSHARE includes the following features:

• Full-Speed LUNs: Each LUN is striped across all of the VIMMs in a flash Memory Array. This ensures that the performance of the LUN is only limited by the performance of the whole Memory array.

• Shared LUNs: Each LUN can be accessed via Fibre Channel and can be shared by many initiators.

• Active-Active highly available configuration: Redundant gateway provides the ability for dual redundant VHP VMA SAN Gateway servicing I/O requests for attached HP VMA Arrays. For best performance, the configuration requires that client initiators use multipath I/O (MPIO) software with a round-robin scheduling algorithm. For more information, see the

Memory Gateway Installation and Configuration Guide

HP VMA SAN

Note: LUNs are accessible in an active-active configuration through either HP VMA SAN Gateway

system configured in a redundant pair. Clients using MPIO can continue I/O through either HP VMA SAN Gateway as long as at least one path is available.

Overview of vSHARE Software Configuration

The vSHARE software configuration must be understood within the context of a HP VMA SAN Memory Gateway deployment. Before you configure vSHARE you must have completed the following:

1. Assembled and cabled the HP VMA SAN Memory Gateway system hardware, as described in the HP

VMA SAN Memory Gateway Installation and Configuration Guide.

2. Defined the network connection, as described in the HP VMA SAN Memory Gateway Installation

and Configuration Guide

3. Configured one or two HP VMA-series Memory Arrays, as described in the HP VMA-series

Installation and Service Guide

4. Configured a HP VMA SAN redundant pair of gateways, as described in the Configuring a

Redundant Pair of VMA SAN Gateways - Process Guide.

Note: Configuring vSHARE is a prerequisite to using a HP VMA SAN Gateway for block storage.

The vSHARE software configuration allows you to define sophisticated rules for controlling access to the LUNs by initiator groups, initiators, or target ports.

20 HP VMA SAN Gateway User’s Guide AM456-9026A

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 W eb Interface. For more information, see CHAPTER 5, “

HP VMA SAN Gateway Interfaces

VMA SAN Gateway Management” on page 127.

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 W eb 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, “

Creating and Deleting LUNs

This section walks you through the process of creating a LUN. Every LUN is created within a container. The size and amount of used space in the container may restrict the number and size of the LUNs created within the container.

AM456-9026A HP VMA SAN Gateway User’s Guide 43

Prerequisites

Verify the block size that is acceptable for the clients (initiators) on your network.

Disk storage systems previously assumed a 512-byte sector or block size as the unit to store data. Newer devices, such as HP VMA Memory Arrays, have a native storage unit sized at 4096 bytes but can also emulate 512 bytes. Not all client operating systems are able to understand accessing anything other than a 512-byte based disk drive.

T o be safe, choose a 512 block size if you are not sure what type of clients will be connected to an exported LUN. For example, RHEL5 and Windows Server 2003 are not be able to properly use a 4096 block-sized disk, and this selection leads to unexpected behavior. For newer op erating systems which support a 4096 block size, the emulation layer can be avoided to provide optimal performance.

To create a LUN, do the following:

1. Select Manage > Manage LUNs. The LUN Management page appears.

2. In the Container panel, select a container from the Container drop-down list. This is the

container in which the new LUN will reside.

3. In the LUNs panel, click the Create New LUNs icon.

The Create LUN window appears.

4. Specify the following:

The number of LUNs in the # LUNs to Make field.

•

• The name of the LUNs in the LUN Name field.

Note: When creating more than one LUN, the name of each new LUN is appended with a number

beginning with 1, and continuing through the number of specified LUNs. This ensures that each LUN has a unique name. Creating a large number of LUNs at once (50 LUNs or more), the operation may take some time.

44 HP VMA SAN Gateway User’s Guide AM456-9026A

5. Define the size of a LUN, in one of the following ways:

To define the size of the LUN based on the space available, select Use all available space

•

equally

• T o manually define the size of each LUN, select Specific size per LUN and enter the size in GB.

Note: The size of the LUNs may be restricted by the space available in the container.

6. Select one of the following block sizes for the LUN:

• 512 bytes

• 4096 bytes.

Caution: Not all systems can handle 4096-byte blocks. Us e 512-byte blocks, if you are not sure what

type of clients will be connected to an exported LUN.

7. Make the following selections, as appropriate:

• Zero-out drive space when creating

LUNs. Zeroing-out data may take some time for large LUNs.

—Securely erases the drive prior to creating the new

• Online—Sets the LUNs online.

Cluster Admin

Cluster administration includes configuration and management tasks for the nodes in a SAN Gateway cluster. A cluster generally consists of two SAN Gateway nodes, a master node and a standby.

The Master SAN Gateway is the current master node in the cluster. The master node works to gether with a standby node to manage the availability of the cluster. When t here are more than two nodes in the cluster, the other nodes are designated as normal nodes.

AM456-9026A HP VMA SAN Gateway User’s Guide 63

In the case of failure of both the master node and the standby node, the cluster continues to operate by electing a new master from the list of available nodes.

Viewing Software Version and Boot Images

The Software section of the Cluster Admin page shows the current software version running on the SAN Gateways, as well as the boot images. Two boot images are installed for each SAN Gateway, each in a separate partition.

To view the software version and choose a boot image, do the following:

You can individually configure several types of SNMP settings through the Web Interface. Simple Network Management Protocol (SNMP) is an Internet standard protocol for managing and monitoring devices on an IP network. For more information, see APPENDIX C, “SNMP T raps” on

page 229.

This section covers the following:

• Enabling SNMP Management on page 84

• Configuring SNMP on page 85

• Setting SNMP Trap Sinks on page 86

Enabling SNMP Management

You can interactively enable and disable SNMP Management from the SNMP Settings page.

To enable or disable SNMP management on your system, do the following:

1. Select Administration > Notification > SNMP Settings.

2. In the upper panel, select the Enable SNMP Management check box. A check mark appears

to show SNMP Management is turned on.

4. Click Apply to activated your selection, or Cancel to return to the previous state.

Configuring SNMP

You can configure SNMP, including settings for the Read-only Community and SNMP Traps Community.

• An SNMP TRAP is a message that is sent out when a significant system event is detected. A

trap sink community defines a host and a community string pair. The community string is the most basic form of SNMP security.

• SNMP community strings are like passwords for network elements. One community string is

often used for read-only access with the default set to “public.” The read-only string is used for the transfer of data between devices.

• A read-write community string is used less often, with a default value of “private.” The read-

write community string provides the ability to change MIB variables on the device.

To configure SNMP settings, do the following:

1. Select Administration > Notification > SNMP Settings.

2. In the SNMP Configuration panel, enter the following information the appropriate text fields:

• SNMP Port:

The port number assigned for SNMP traffic

• System Location: IP address of the SNMP server

• System Contact: The email address for the system administrator

3. Enable or disable the following options by selecting the check box next to the option, then

from the drop-down list choose between Public, or Private:

• Read-Only Community

• SNMP Traps Community

4. Click Apply to activated your selection, or Cancel to return to the previous state.

AM456-9026A HP VMA SAN Gateway User’s Guide 85

Setting SNMP Trap Sinks

A trap sink defines a host and a community string pair. When a trap event occurs the SNMP agent sends out a trap to each host in the trap sink list using the community string. This section shows you how to configure a trap sink list, by removing, enabling, disabling, and adding SNMP servers (hosts) to be included in the list.

The SNMP Trap Sinks panel lists configured SNMP servers, their type-version (type of security implemented as related to the version of SNMP), if SNMP management is enabled or not, and the community configuration. For more information on the available SNMP traps, see Available Traps on page 234.

CHAPTER 3 vSHARE Configuration

This chapter describes vSHARE features and functions, and the steps required to configure a HP VMA SAN Gateway running vSHARE to manage block storage. The following topics are covered:

• Understanding vSHARE on page 93

• Configuring Storage Containers on page 96

• Configuring Target Ports on page 99

• Configuring Initiator Groups on page 100

• Creating LUNs on page 102

• Resizing LUNs on page 105

• Exporting LUNs on page 106

• Optimizing Connectivity to Storage Arrays for Windows on page 107

Understanding vSHARE

vSHARE is a software application that provides a solution for block storage management. vSHARE runs on a HP VMA SAN Gateway enabling host systems (such as database servers) to use the Fibre Channel transport protocols to access logical units of data (LUNs) stored within Memory Arrays:

On the host system, the LUN appears as a local SCSI disk. The host formats and partitions the LUN, and the storage system sees the contents of a LUN as a set of blocks of arbitrary data.

Administrators can 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.

AM456-9026A HP VMA SAN Gateway User’s Guide 93

• Storage Containers: A HP VMA-series Memory Array contains a storage container;

Storage Management

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 A vailability , see the

Pair of VMA SAN Gateways - Process Guide.

Configuring a Redundant

A typical vSHARE cluster consists of one or more HP VMA Array running the vSHARE software application and one or more HP VMA Arrays.

Figure 3.1 vSHARE System Architecture

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 SAN Gateways and Memory Arrays are connected via PCIe cables.

94 HP VMA SAN Gateway User’s Guide AM456-9026A

initiators. The SAN Gateway provides network connectivity, utilizing Fibre Channel. The

Target Ports

You can view information for target ports using the show targets command. For more information, see show targets Command on page 100. .

vSHARE Configuration Overview

The steps to configure a vSHARE HP VMA SAN Gateway using Fibre Channel are outlined in the following flowchart.

Figure 3.2 vSHARE Deployment Flowchart

1. Configuring Storage Containers on page 96. This step initializes the HP VMA-series Memory Array

to manage block storage and create one or two storage containers (partitions) to manage the LUNs. To format the HP VMA-series Memory Array from vSHARE, the media init command is requ ired. This command enables you to initialize one or more memory arrays to support block storage. Once a memory array has been initialized to support block storage, you may create one or two storage containers on each memory array, which may be used to store and manage LUNs.

2. (Optional) Configuring Target Ports on page 99. This step configures the target ports so they

can control access to LUNs. Configuring target ports is useful for security and bandwidth management.

Note: Configuring target ports and initiator groups are optional steps in the vSHARE

configuration process. Organizations that do not want to use LUN-masking can control access to LUNs through ports or switches. LUN masking is an authorization process used to make a logical unit number available to some hosts and unavailable to others.

3. (Optional) Configuring Initiator Groups on page 100. This step configures the initiator

groups, adding one or more initiators to each initiator group. You can restrict access to LUNs by initiator group, or on a per-initiator basis.

AM456-9026A HP VMA SAN Gateway User’s Guide 95

4. Creating LUNs on page 102.

LUNs are created within a storage container that comprises a particular HP VMA-series Memory Array . A LUN inherits the attributes of the container (HP VMA-series Memory Array) in which it is created.

Note: As of this release, one container comprises a HP VMA-series Memory Array.

5. Exporting LUNs on page 106. This required step exports the LUNs to the initiator groups or

initiators via target ports. Only those initiator groups or initiators to which the LUN is exported may access the LUN. Access may be further restricted to a specific target port.

Configuring Storage Containers

The first step in configuring a vSHARE SAN Gateway is to format the Memory Arrays to create the necessary containers.

Note: As of this release, one container comprises a HP VMA-series Memory Array.

In vSHARE, LUNs are addressable subsets of the flash memory within a HP VMA-series Memory Array. Every LUN created and managed by vSHARE is created within the storage container that comprises the Array.

When a LUN is created, it is assigned to a specific container and inherits the attributes of that container. Configuring a Storage Container follows this process:

1. Initializing HP VMA-series Memory Arrays on page 96

2. Viewing Containers on page 98

Initializing HP VMA-series Memory Arrays

T o configure a HP VMA-series Memory Array to support block storage, you must first initialize the HP VMA-series Memory Array using the topics:

• Command Syntax and Parameters on page 96

• Configuring Block Storage on page 97

media init command, as covered in the following

Command Syntax and Parameters

This section presents the correct command syntax for the

media init command and lists and

explains the available parameters.

96 HP VMA SAN Gateway User’s Guide AM456-9026A

Syntax

media init device <VIOLIN_MEMORY_ARRAY_xxxxxxxxxxxxxx> type [block] [force][name]

WARNING! Using the force option of the media init command (media init <device_name>

<block_name> force) destroys the existing data on an array. You should not use this command on a

previously initialized array without first backing up the data on the array.

Parameters

device <device>

type

name

The <device> parameter indicates the array to be initialized and is a string of the form:

VIOLIN_MEMORY_ARRAY_xxxxxxxxxxxxxx

ata-

The type parameter defines media. The name parameter is used to name the partition. The default is to

use the last 14 characters of the HP VMA-series Memory Array serial number. To use a different name, add this parameter followed by a custom name of choice. The name can be up to 14 alphanumeric characters in length.

force

The force parameter is used to force initialization of a HP VMAseries Memory Array that has already been initialized.

Configuring Block Storage

This section demonstrates how to initialize a HP VMA Array for block storage.

To initialize the HP VMA-series Memory Array for block storage, complete the following steps:

1. Log in as administrator to the master SAN Gateway through a terminal port, such as PuTTY.

2. Enter Configure mode, using the following commands.

> enable # configure terminal

(config) #

3. Enter the media init command to initialize the HP VMA-series Memory Array.

(config) # media init device ata-VIOLIN_MEMORY_ARRAY_23108R00000043 type block

This example generated the container ID: 23108R00000043.

AM456-9026A HP VMA SAN Gateway User’s Guide 97

4. (Optional) Use the name parameter to create a more intuitive name for the container ID. In the

following example, the generated container ID is changed to FASTBOX1:

(config) # media init device ata-VIOLIN_MEMORY_ARRAY_23108R00000043 type block name FASTBOX1

5. Confirm that you want to initialize the HP VMA-series Memory Array.

Really initialize ata-VIOLIN_MEMORY_ARRAY_FASTBOX1 (all data will be lost)? [no] y

command to enable the device, then use the show containers command to view existing

containers.

media block id <id>

To view existing containers, complete the following steps:

1. Log in as an administrator to the master SAN Gateway attached to Port 1 of the HP VMA-

series Memory Array.

2. Enter Configure mode using the following commands.

> enable # configure terminal

(config) #

3. Enter the media block id all enable command to enable all block containers.

(config) # media <tab>

(config) # media block id all enable

C-2 150 199G 50176M A,B <hostname> <hostname> Single

Configuring Target Ports

The second step in configuring a vSHARE SAN Gateway is to configure the target ports. The target ports control access to a particular LUN, which may be useful for both security and bandwidth management.

This section covers the following topics:

• Supported Target Ports on page 99

• Configuring Fibre Channel Target Ports on page 99

Supported Target Ports

In a vSHARE system, the HP VMA-series Memory Arrays are the targets and the host system (such as, one or more database servers or application servers) are the

initiators. The storage systems have

storage target devices, LUNs, which the hosts access through the SAN Gateway. vSHARE supports the Fibre Channel target port type.l

Every target is a specific port on a hardware Fibre Channel host bus adapter (HBA).

• For Fibre Channel, the target ports are present when the SAN Gateway boots, if the HBAs are

installed on the system. Creating a container is not necessary.

Note: A LUN can be exported through multiple tar get ports. Active-active multipathing is supported.

Configuring Fibre Channel Target Ports

For Fibre Channel, the target ports are present when the SAN Gateway boots when the HBAs are installed on the system.

To confirm that the vSHARE system can see the target ports prior to creating the initiator groups, use the ports.

show targets command. The show targets command allows you to view all target

AM456-9026A HP VMA SAN Gateway User’s Guide 99

show targets Command

The

show targets command lists all of the target ports and their addresses (wwn), filtered by

various options.

Syntax

show targets [node <cluster node id>] [hostname <hostname>] [protocol fc] [id <target id>] [sessions] [detail]

Parameters

[node <cluster node id>]

[hostname <hostname>]

[protocol fc]

[id <target id>]

[sessions]

[detail]

Configuring Initiator Groups

The third step in configuring the vSHARE system is to configure the initiator groups (igroups) that identify the initiators (hosts) allowed to access a LUN or set of LUNs.

Every initiator has a protocol-specific identifier.

• Fibre Channel initiators are identified by World-Wide Names (WWN). Fibre Channel initiators are fixed by the appropriate HBA port.

Displays targets on node ID. Displays targets on hostname. Displays targets using protocols FC. Displays a specific target. Displays targets including sessions. Displays in detail.

Initiator Group Configuration

To configure an initiator group, complete the following steps:

1. From the CLI, use the enable command (to enter Enable mode), and then the configure

terminal

> enable

# configure terminal

(config) #

2. Use the igroup name command to create an initiator group, as shown in the following

command (to enter Configure mode).

example.

(config) # igroup create name <my_igroup>
