Introducing DDVE

DD Virtual Edition (DDVE) is a software-only protection storage appliance: a virtual deduplication appliance that provides data protection for entry, enterprise and service provider environments. Like any DD system, DDVE is always paired with backup software.

DDVE runs the DD Operating System (DD OS), and includes the DD System Manager graphical user interface (GUI) and the DD OS command line interface (CLI) for performing system operations.

DDVE includes the following features:

High-speed, variable length deduplication for a 10 to 30 times reduction in storage requirements

Unparalleled data integrity to ensure reliable recovery, and seamless integration with leading backup and archiving applications

DD Boost to speed backups by 50 percent

DD Encryption for enhanced security of data

DD Replicator for network efficient replication that enables faster time-to-DR readiness

DDVE runs on two types of platforms:

On premises, DDVE supports VMware, Hyper-V, KVM, and VxRail.

In the cloud, DDVE also runs in the Amazon Web Services (AWS) (cloud and gov cloud), Azure (cloud and gov cloud), VMware Cloud (VMC) on AWS cloud platforms, and Google Cloud Platform (GCP).

For more information about the features and capabilities of DD systems (both physical and virtual), see the

DD Operating System Administration Guide

DDVE features

Resource configurations depend on your DDVE configuration. For features for cloud configurations within the admin guide for your specific cloud provider, see DDVE cloud features on page 10.

Deploying DDVE

Preparing your environment to deploy DDVE on Azure

While DDVE is running in Azure cloud, you can backup and restore your operational data from Azure hot blob storage.

The following sections provide general guidelines to deploy, configure, and run DDVE on Azure with Active Tier on Azure hot blob storage. The high-level steps are as follows:

1. Set up the network environment. For secure access to the DDVE instance, Dell EMC recommends that you use the virtual network architecture provided by Azure. Set up and configure the following components:

Resource group

Virtual network

Subnets

Network Security groups

Service endpoint for connectivity to Microsoft.Storage

Virtual Network service endpoints provides more information.

Networking Best Practices for DDVE in the Cloud on page 55 provides more information.

2. Create a StorageV2 storage account in the same region where DDVE will be deployed and add a new hot blob container as the backup storage. Select the following values:

Performance—Standard

Account kind—General-purpose V2

Access tier—Hot

Ensure that the container is empty.

Create an Azure Storage Account provides instructions. What is Azure Blob Storage? provides

more information.

3. For secure login to DDVE through SSH, create an SSH key pair. How to use SSH keys with

Windows on Azure provides instruction.

4. Ensure that your system meets the requirements for DDVE on Hot blob storage. Azure provides several disk types. Standard HDD is recommended for the DDVE OS disk and the vNVRAM disk. You can use either Standard HDD (cost effective) or Standard SSD (better performance) for metadata disks.

Ensure that you select the correct DDVE virtual machine instance type for your capacity and workload.

Deploying DDVE from the Azure Marketplace

Use this procedure for initial deployment of DDVE from the Azure Marketplace.

About this task

The URLs for Azure storage accounts and other services are as follows:

Azure Global Cloud: *.blob.core.windows.net

Azure Government Cloud: *.blob.core.usgovcloudapi.net

Network Interface

PowerProtect DD Virtual Edition in the Azure Cloud Installation and Administration Guide 17

Deploying DDVE

Procedure

1. Log in to the Azure portal.

For Azure Gov Cloud: https://portal.azure.us:

AzureRmSubscription - SubscriptionId <subscription_id>

2. Search for Dell EMC to find Power Protect DD Virtual Edition in Azure Marketplace.

3. Begin the deployment.

4. Configure the following settings:

Name: Enter a name for DDVE. (Maximum length is 10 characters. For Azure Gov Cloud, maximum length is six characters. )

Note: The maximum length of the fully qualified domain name (FQDN) can be no

longer than 63 characters.

VM disk type: Select Standard HDD.

Username: Enter sysadmin.

Authentication type: Both SSH publicKey and password authentication are supported. (SSH publicKey authentication type forces a password change at first login.)

Adding metadata disks in Azure

Although Azure provides two types of disk storage, Premium and Standard, DDVE supports only Standard. After DDVE is deployed in Azure, a 10 GiB vNVRAM disk is created automatically.

Note: DDVE supports both Standard HDD and Standard SSD. Dell EMC recommends Standard

HDD for cost-effectiveness or Standard SSD for performance.

You can add managed or unmanaged disks to DDVE in Azure. For template-based deployments, only unmanaged disks are supported.

It is not necessary to shut down the virtual machine before adding storage.

The virtual disk cannot be resized. You must create a new virtual disk to add additional storage to the virtual machine.

Required capacity

Metadata disk capacity—The required metadata capacity varies based on workload. Dell EMC recommends that metadata capacity be equal to 10% of the total DDVE capacity, which is sufficient for most workloads. The addition of additional metadata disks can increase cost.

Licensed capacity—Make sure you have enough licensed capacity available to add new capacity to DDVE and make sure the DDVE instance can support the new capacity. If the new capacity is more than the DDVE instance's supported capacity, please upgrade the DDVE instance.

Deploying DDVE

Metadata disk requirements

New storage for DDVE on hot blob storage must meet the following requirements:

The minimum size of the first metadata disk is 1 TiB.

Azure limits metadata disks to a maximum of 4,095 GiB.

The recommended size for all metadata disks is 1 TiB. For example, if 10 TiB of metadata capacity are required, configure ten 1 TiB metadata disks.

For unmanaged metadata disks, create separate containers with different names for the metadata disks and the object-store profile.

In template-based deployments, the default container name for metadata disks (DDVE on hot blob storage) or data disks (DDVE on block storage) is <vmName>-vhds.

In marketplace deployments, the default container name for metadata disks (DDVE on hot blob storage) or data disks (DDVE on block storage) is vhds.

Any subsequent metadata disks must be a minimum of 1 TiB.

Adding managed disks in Azure

Use these procedures to add managed disks to DDVE in Azure.

Procedure

1. Allocate and attach managed disks to DDVE:

a. Log into the Azure portal.

b. Search the name of the DDVE virtual machine.

c. In the right pane under SETTINGS, select Disks.

d. Click Add data disk.
