Application Version and Upgrade Details

Introduction

NetApp SolidFire overview

SolidFire storage is an interconnection of hardware and software designed for complete automation and management of an entire SolidFire storage system.

NetApp SolidFire Architecture

The following diagram shows the basic layout of the SolidFire Storage System and how it connects to a network:

Cluster, Nodes, and Drives

Cluster

A cluster is the hub of a SolidFire Storage System and is made up of a collection of nodes. You must have at least four nodes in a cluster (five or more nodes are recommended) in order for SolidFire storage efficiencies to be realized. A cluster appears on the network as a single logical group and can then be accessed as block storage.

Creating a new cluster initializes a node as communications owner for a cluster and establishes network communications for each node in the cluster. This process is performed only once for each new cluster.

One can increase the scalability of the cluster by additional nodes upto 100. Adding additional nodes doesn’t cause any interruption of the service and the cluster automatically uses the performance and capacity of the new node.

The following diagram illustrates the basic Ip Address layout for the cluster.

Administrators and hosts can access the cluster using virtual IP addresses. Any node in the cluster can host the virtual IP addresses. The Management Virtual IP (MVIP) enables cluster management through a 1GbE connection, while the Storage Virtual IP (SVIP) enables host access to storage through a 10GbE connection.

These virtual IP addresses enable consistent connections regardless of the size or makeup of a SolidFire cluster. If a node hosting a virtual IP address fails, another node in the cluster begins hosting the virtual IP address.

Nodes

Nodes are individual hardware components that are grouped into a cluster to be accessed as block-storage. There are two types of nodes in the SolidFire Storage system. They are Storage Nodes and Fibre-Channel Nodes.

Storage Nodes

A SolidFire storage node is a server containing a collection of drives that communicate with each other through the Bond10G network interface. Drives in the node contain block and metadata space for data storage and data management.

Storage nodes have the following characteristics:

• Each node has a unique name. If a node name is not specified by an administrator, it defaults to SF-XXXX, where XXXX is four random characters generated by the system.
• Each node has its own high-performance non-volatile random access memory (NVRAM) write cache to improve overall system performance and reduce write latency.
• Each node is connected to two networks, storage and management, each with two independent links for redundancy and performance. Each node requires an IP address on each network.
• You can create a cluster with new storage nodes, or add storage nodes to an existing cluster to increase storage capacity and performance.
• You can add or remove nodes from the cluster at any time without interrupting service.

Fibre Channel(FC) Nodes

SolidFire Fibre Channel nodes provide connectivity to a Fibre Channel switch, which you can connect to Fibre Channel clients. Fibre Channel nodes act as a protocol converter between the Fibre Channel and iSCSI protocols; this enables you to add Fibre Channel connectivity to any new or existing SolidFire cluster.

Fibre Channel nodes have the following characteristics:

• Fibre Channel switches manage the state of the fabric, providing optimized interconnections.
• The traffic between two ports flows through the switches only; it is not transmitted to any other port.
• Failure of a port is isolated and does not affect operation of other ports.
• Multiple pairs of ports can communicate simultaneously in a fabric.

Drives

A storage node contains one or more physical drives that are used to store a portion of the data for the cluster. The cluster utilizes the capacity and performance of the drive after the drive has been successfully added to a cluster.

A storage node contains two types of drives:

1. Volume metadata drives- volume metadata drives store the compressed information that defines each volume, clone, or snapshot within a cluster. The total metadata drive capacity in the system determines the maximum amount of storage that can be provisioned as volumes. The maximum amount of storage that can be provisioned is independent from how much data is actually stored on the block drives of the cluster. Volume metadata drives store data redundantly across a cluster using Double Helix data protection.

   Note: Some system event log and error messages refer to volume metadata drives as slice drives.

2. Block drives- block drives store the compressed, de-duplicated data blocks for server application volumes. Block drives make up a majority of the storage capacity of the system. The majority of read requests for data already stored on the SolidFire cluster, as well as requests to write data, occur on the block drives. The total block drive capacity in the system determines the maximum amount of data that can be stored, taking into account the effects of compression, thin provisioning, and de-duplication.

Use Cases

Discovery Use Cases:

• Provides resource visibility to the administrator to view and manage resources available (Ex: Cluster, Nodes, Drives, Volume Accounts and Volumes) under different resource types
• Publishes relationships between resources to have a topological view and ease of maintenance

Monitoring Use Cases:

• Provides metrics related to Memory Utilization, Performance Utilization and so on for different resources
• Concern alerts will be generated for each metric to notify the administrator regarding the issue with the resource.

Prerequisites

• OpsRamp Nextgen Gateway supported version 14.0.0 and above.
• OpsRamp Classic Gateway supported version 14.0.0 and above.
  Note: OpsRamp recommends using the latest Gateway version for full coverage of recent bug fixes, enhancements, etc.

Default monitoring configurations

NetApp SolidFire application has default Global Device Management Policies, Global Templates, Global Monitors and Global metrics in OpsRamp. You can customize these default monitoring configurations as per your business use cases by cloning respective global templates and global Device Management Policies. OpsRamp recommends performing the below activity before installing the app to avoid noise alerts and data.

1. Default Global Device Management Policies

   OpsRamp has a Global Device Management Policy for each Native Type of NetApp SolidFire. You can find those Device Management Policies at Setup > Resources > Device Management Policies, search with suggested names in global scope. Each Device Management Policy follows below naming convention:

   {appName nativeType - version}

   Ex: netapp-solidfire NetApp SolidFire Cluster - 1 (i.e, appName = netapp-solidfire, nativeType = NetApp SolidFire Cluster, version = 1)

2. Default Global Templates

   OpsRamp has a Global Template for each Native Type of NetApp SolidFire. You can find those templates at Setup > Monitoring > Templates, search with suggested names in global scope. Each template follows below naming convention:

   {appName nativeType 'Template' - version}

   Ex: netapp-solidfire NetApp SolidFire Cluster Template - 1 (i.e, appName = netapp-solidfire, nativeType = NetApp SolidFire Cluster, version = 1)

3. Default Global Monitors

   OpsRamp has a Global Monitors for each Native Type which has monitoring support. You can find those monitors at Setup > Monitoring > Monitors, search with suggested names in global scope. Each Monitors follows below naming convention:

   {monitorKey appName nativeType - version}

   Ex: SolidFire Cluster Monitor netapp-solidfire NetApp SolidFire Cluster 1 (i.e, monitorKey = SolidFire Cluster Monitor, appName = netapp-solidfire, nativeType = NetApp SolidFire Cluster, version = 1)

Application Migration

1. Check for the gateway version as a prerequisite step - classic gateway-12.0.1 and above.
   Notes:

   • You only have to follow these steps when you want to migrate from sdk 1.0 to sdk 2.0.
   • For first time installation below steps are not required.
     • Application name should be the same.
     • Disable all installed integrations configurations for that application. This is to make sure no discovery and monitoring requests are processed.
     • Install and Add the configuration to that sdk 2.0 application.
       Note: refer to Configure and Install the NetApp SolidFire Integration & View the Netapp SolidFire Details sections of this document.

2. Once all discoveries are completed with the sdk 2.0 applicaion, follow any one of the approaches.
