Technology overview
Dell EMC customers benefit in leveraging this integrated solution for their primary workload data protection
and cloud backup needs. This integrated solution offers Virtual Machine (VM) deployment and lifecycle
management for the combined solution offering. Protection for newly deployed and existing VMs. Usage of
policies and best practices and the consequent streamlining of the data protection workflow to the cloud are
the primary goals for this solution. This section provides an overview of the products used to validate the
solution.
2.1
Dell EMC XC Series Hyper-converged appliances
Dell EMC XC Series hyper-converged appliances start with the proven Dell PowerEdge server platform and
incorporate many of the advanced software technologies that power leading scalable and cloud
infrastructures. Backed by Dell EMC global service and support, these 1- and 2U appliances are
preconfigured for specific virtualized workloads, and are designed to maintain data availability in case of
appliance and disk failure.
The XC Series infrastructure is a scalable cluster of high-performance appliances, or servers, each running a
standard hypervisor and containing processors, memory, and local storage (consisting of solid state disk
(SSD) flash for high performance and high-capacity SATA disk drives). Each appliance runs virtual machines

2.1.1
Nutanix architecture
Nutanix software provides a hyper-converged platform that uses DSF to share and present local storage to all
the virtual machines in the cluster. The general Nutanix architecture is shown in Figure 2.
Nutanix Architecture.
DSF virtualizes local storage from all appliances into a unified pool. DSF uses local SSDs and disks from all
appliances to store virtual machine data. Virtual machines running on the cluster write data to DSF as if they
were writing to shared storage. XC Series supports multiple hypervisors and provides choice to customer.
XC Series offers customer choice of hypervisors without being locked-in. The hypervisors covered in this
reference architecture are:


VMware® ESXi®
Microsoft® Hyper-V®
In addition, the solution includes the Nutanix Controller VM (CVM), which runs the Nutanix software and
serves I/O operations for the hypervisor and all VMs running on that host. Each CVM connects directly to the
local storage controller and its associated disks thereby reducing the storage I/O latency. The data locality
feature ensures virtual machine I/Os are served by the local CVM on the same hypervisor appliance,
improving the VM I/O performance regardless of where it runs.

are rarely accessed; however, IT must retrieve backups on demand as either full or incremental restores.
DataDomain Cloud Tier is architected for files and data that are infrequently accessed. The ideal candidates
for Cloud Tier are data past their normal recovery window or useful active life.
Examples of such data are:
 Years old email messages
 Application data and files needed for legal hold
 Archiving
 Long term retention policies
Common use cases for Data Domain Cloud Tier:
 Meet regulatory and compliance policies
 Reduce costs with low cost object storage in the cloud (on-prem or public)
 Migrate data from tape to cloud
 Cold storage archiving with limited retrieval of data
In this solutions guide we demonstrate cloud tier integration facilitated through Data Domain Virtual Edition
(DD VE) and/or DD6800 appliances to the following cloud offerings:


Microsoft Azure
Virtustream
Data Domain Cloud Tier moves data seamlessly from Data Domain to the cloud, with no separate cloud
gateway or virtual appliance required. There is no additional physical footprint or management overhead.
Simply set your data movement policy and data is automatically moved from the active Data Domain tier to
the Cloud Tier and sent to the cloud for long-term retention.

The VMs associated with an appliance are backed up by Avamar and
stored on a Data Domain target. Backing up of the VM reflects full
backup protection of the VM as well as the applications running in that
VM.
Exchange Mailbox backup (ondemand) and restore
Full or incremental backups of a specific database or storage group
including the database file and the transaction log and checkpoint files
for the database or storage group.
SQL backup (on-demand) and
restore
Full or incremental backups either all SQL Server data on a specific
server, one or more instances, or one or more databases.
4.1
Configuring the Data Domain cloud tier
4.1.1
Setting up target cloud providers
You must open TCP port 443 (https) and/or TCP port 80 (http) to the cloud provider networks for both the
endpoint IP and the provider authentication IP for bi-directional traffic. Remote cloud provider destination IP
and access authentication IP address ranges must be allowed through your firewall.
Note: Several public cloud providers use IP ranges for their endpoint and authentication addresses. In this
situation, the IP ranges used by the provider must be unblocked to accommodate potential IP changes.
Contact your public cloud provider for details on your specific endpoint and authentication IP addresses.
The only difference between adding Azure and adding Virtustream to the Data Domain Cloud Tier are the

Best practice recommendations
6.1
Data Domain cloud tier best practices
The cloud tier feature can use all of the available bandwidth to the cloud, which may impact other applications
sharing the WAN link. In addition, data-movement to the cloud has return traffic due to protocol handshake
and acknowledgements. This is expected to be about two percent of the outgoing traffic but can have spikes
as high as seven percent depending on the network and cloud provider responses.
The best practice for Cloud Tier is to use dedicated 1-10 Gbps networks for connectivity to the cloud storage
provider. In addition, Dell EMC recommends you use network quality of service (QoS) and/or dedicated cloud
storage networks to avoid congestion and to ensure consistent performance in shared network environments
where multiple applications access the same network.

Conclusion
The solution detailed in this paper shows that Dell EMC XC Series can be integrated with Dell EMC Data
Protection solutions (Avamar Virtual Edition and Data Domain) to offer robust backup and recovery of data,
VMs, Exchange Mailboxes, and SQL Databases that needs to be backed-up to Cloud Providers (such as
Azure and Virtustream) for long-term retention purposes.

Understanding Active, Marked, and Cloud tier
When Avamar backs up data and the cloud tier is enabled, the backed up data goes through different states.
Avamar Administrator Backup & Restore screen shows backup as Active on the Manage tab.
When the backup occurs, it is initially stored on the Data Domain in the Active tier. This is shown in the
Avamar Administrator Backup & Restore screen under the Manage tab as Active.
139
Data Domain Cloud Tier for Dell EMC XC Series Hyper-Converged Appliances – Solutions Guide | 000030 | A01
Showing the status as Marked. Data has yet to move to cloud storage.
After the backup has exceeded the time defined in the Cloud Tier Group schedule, it is moved from the active
tier storage to the cloud tier storage on Data Domain. This is shown in the Avamar Administrator Backup &
Restore screen under the Manage tab as Marked. At this point the backup is still on the Data Domain and
has not moved yet to the cloud storage.
Status now shows as Cloud, meaning it has been moved to the cloud.
After Data Domain moves the backup from its cloud tier storage area to the cloud storage provider (Azure,
Virtustream), the backup is shown in the Avamar Administrator Backup & Restore screen under the manage
tab as Cloud.
