5 Dell EMC PowerProtect DD Virtual Edition on Microsoft Azure | H18832
Introduction
1 Introduction
DDVE is a software-defined data protection solution of PowerProtect DD series appliance, with all the core
differentiating features of DD series.
DDVE runs the DD Operating System (DDOS) and includes the DD System Manager graphical user interface
(GUI) and the DDOS 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 can be deployed on any standard hardware, converged or hyperconverged, and runs in VMware
vSphere, Microsoft Hyper-V, KVM, as well as in-cloud with Amazon Web Services(AWS)(cloud and gov cloud),
VMware Cloud(VMC), Azure(cloud and gov cloud) and Google Cloud Platform(GCP). DDVE is also certified
with VxRail™ and Dell PowerEdge servers.
DDVE scales up to 256 TB (in-cloud AWS, Azure, and Google Cloud) and up to 96 TB (on-premises) per
instance.
1.1 DDVE cloud features
DDVE provides the capabilities of a cloud DD system using the following resource configuration sizes:
• DDVE on Block storage- up to 16 TB
o DDVE capacity is available in 1 TB increments starting at 512 GB.
• DDVE on Hot Blob storage(recommended) - up to 256 TB
Supported DD protocols:
• DD Boost over IP
• DD Boost FS
Supported DD features:
• DD Boost managed file replication (MFR)
• Encryption
• MTree replication
• DD System Manager GUI for DDVE management
• DD Active Tier (DD Cloud Tier is not supported)
• Secure multitenancy (SMT) with Network Isolation Support
• DD Boost/BoostFS for Big Data
• Key Management Interoperability Protocol (KMIP)
• More restricted IPtables settings
• Azure for Government Cloud
6 Dell EMC PowerProtect DD Virtual Edition on Microsoft Azure | H18832Introduction
Note: DDVE supports these replication capabilities:
• Managed file replication and MTree replication.
• Replication across availability zones and regions.
• Bi-directional replication between on-premises and Azure
1.2 Architecture overview
The following diagram represents the architecture of the DDVE on Microsoft Azure Cloud solution.
1. To keep data traffic between DDVE and Azure storage within the Azure infrastructure, it is
recommended to create an Azure storage service endpoint. The service endpoint keeps DDVE from
depending on a NAT Gateway or Public IP address to access the hot blob container.
2. Dell Technologies recommends a VPN connection to replicate data from an on-premises host to DDVE
in the cloud or the opposite way. This approach keeps data transfers secure.
3. DDVE is categorized as a backend server. It must be kept in a private subnet with a private address.
Never set a public IP address for DDVE.
4. The storage account must be in the same region where the DDVE instance is running. A separate hot
blob storage account with a container is required for each DDVE.
5. All DDVE instances must be secured with the appropriate security group entries.
Note:
• Typically, SSH (Port 22) or HTTPS (Port 443) is used for DDVE inbound access.
• HTTPS (443) must be allowed for outbound Azure hot blob container access for DDVE.
• TCP ports 2049 and 2051 are used for DD Boost and replication purposes.

2 Deploying DDVE on Azure
2.1 Prerequisites to deploy DDVE on Azure
2.1.1 Setup the network environment
For secure access to the DDVE instance, it is recommended to use the virtual network architecture that Azure
provides. For more details refer Azure Virtual Network concepts and best practices. Setup and configure the
following components:
• Resource group
• Virtual network
• Subnets
• Network Security groups
• Service endpoint for connectivity to Microsoft.Storage
2.1.2 Enable VNet service endpoint to Azure storage
The DDVE object store solution requires network connectivity to the object storage container. To route traffic
directly from the virtual network to the storage service on the Microsoft Azure backbone network, it is
recommended to enable Virtual Network (VNet) service endpoints to Azure storage. By default, the Azure VNet
service endpoints are disabled. It can be enabled on the subnet in the virtual network.
Steps:
• In the VPC pane, click Service endpoint and + Add.
• In the popup window, in the service column, select Microsoft.Storage.
• In the subnet column, select the subnets.
2.1.3 Create a container in Azure hot blob storage
A storage account is required in the same region where DDVE is deployed. Create a separate storage account
for each DDVE.
Steps involved are as follows:
1. Create a StorageV2 account in the same region where DDVE is deployed.

12. DDVE instance is running and ready for configuration.
Note: Adding metadata disks in Azure
DDVE uses disks to save metadata.
• Managed disk is recommended. Azure also enables to convert unmanaged disks to managed
disks.
• It is not necessary to shut down the virtual machine before adding metadata disks.
• The metadata disk is not usually resized. To add more storage to the virtual machine, a new virtual
disk can be created.
• 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. If the workload is using a higher deduplication ratio, consider adding more
metadata disks.
• Licensed capacity—Ensure that the DDVE instance can support the licensed capacity. If the new
licensed capacity is more than the supported capacity of the DDVE instance, upgrade the DDVE
instance.
For more details on adding metadata disks, converting metadata disk types, resizing the DDVE instance refer

24 Dell EMC PowerProtect DD Virtual Edition on Microsoft Azure | H18832Best Practices
4 Best Practices
4.1 Supportability
Azure supports interactive serial console, which can help to debug boot up and networking issues, troubleshoot
malfunctioning instance, interact with Grand Unified Bootloader (GRUB), and perform other troubleshooting
tasks. It is recommended to do the following.
• Enable the "Boot Diagnostics" feature during deployment for troubleshooting.
• Enable ASUP in DDVE
4.2 Azure Licensing
The DDVE license is node locked, which means the same license cannot be used on multiple DDVE instances.
To facilitate DDVE license management, it is recommended to use served-mode license if multiple DDVEs will
be deployed.
4.3 Power Control
It is recommended to use DDOS interfaces to power-off or reboot the DDVE instance. If the virtual machine is
powered-off using the Azure interface, it might not shut down cleanly.
4.4 Storage best practices
The virtual disk that is allocated to the virtual machine is discovered automatically. However, it is recommended
to explicitly add it to the DDVE storage active tier and create or expand the file system.
4.4.1 Data disk limitations
• The maximum size of each disk is 4 TB, the recommended size is 1 B for performance consideration.
• VM size determines the maximum number of data disks for the Azure VM instances that DDVE uses. See
Virtual Machine sizes for data disk limitations (the root disk and resource disk that Azure adds are not
counted in this limitation). The NVRAM emulation disk is also counted as one data disk for Azure.
4.4.2 Expanding DDVE on block storage
DDVE capacity can be dynamically expanded by adding more data disks to the instance. Increments of 1 TB
are recommended. When the maximum capacity that the instance supports is reached, it is recommended to
upgrade the VM to a larger size before adding more storage to the system. Do not manually set or change the
spindle group setting when adding storage. DDVE automatically assigns the spindle group.
4.4.3 Expanding DDVE on hot blob storage
The local block storage is used for caching metadata. Based on different workloads, the needed metadata size
varies. Dell Technologies recommends configuring the metadata storage size as 10% of total capacity, which
is enough for most workloads. For workloads with a higher deduplication ratio, more metadata is needed.
Metadata storage can be dynamically expanded. When the metadata storage space usage exceeds 80%, an
alert is raised. Immediately add a metadata disk to the DDVE to avoid running out of space.
25 Dell EMC PowerProtect DD Virtual Edition on Microsoft Azure | H18832Best Practices
4.4.4 Hot blob storage location
When DDVE is used on hot blob storage, ensure that the hot blob storage account and DDVE instance are in
the same region. Configuring the VM and storage account in different regions can result in lower performance
and higher costs.
4.4.5 Create separate account for each DDVE
Azure infrastructure throttles each storage account, and each storage account has its own IOPS and throughput
limits. For best performance, create a separate storage account for each DDVE.
4.4.6 Disk caching
Host-caching is not supported for data disks (DDVE on block storage) or metadata disks (DDVE on hot blob
storage). Changing the cache setting of an Azure disk detaches and reattaches the target disk. For the operating
system disk, the VM is restarted. Ensure to stop all applications and services that this disruption might affect
before changing the disk cache setting.
4.4.7 Converting from evaluation to production
Rather than convert an evaluation version of DDVE to a production version, Dell Technologies recommends a
fresh deployment. If it is required to convert from an evaluation to production version, Dell Technologies
recommends:
• Destroy the existing file system
• Delete small data disks (not the root, NVRAM disks)
• Configure new disks according to the recommendations
4.5 Security best practices
• Avoid public IP address to configure the system.
• For better security, it is recommended to disable authentication that is based on username and password.
If the username-and-password-based authentication is desired, it is recommended to configure a strong
password.
• After protecting the DDVE using secure setup, within DDVE network traffic that enters can be filtered by
using the iptables feature.
• Since the DDVE in AWS is always running in a VPC, the VPC should be configured so that only required
and trusted clients have access to the DD system.
4.6 Network best practices
• It is recommended to use public or private subnet architecture to deploy the DDVE in private subnet.
• It is highly recommended to use VPN connections between different geographical regions (VNets).
• The DDVE object store feature needs connectivity to its object storage, such as to the Azure storage
account container. Because the object store communication is over https, the outbound security group
setting must allow communication over port 443. There are different ways to enable DDVE connectivity to
the object store and the recommended one is using a VNet service endpoint for accessing the Azure hot
blob storage.
