Technology overview


2 Technology overview Dell EMC customers benefit in leveraging this integrated solution for their primary workload data protection

needs. Protection for newly deployed and existing VMs. Usage of policies and best practices and the

consequent streamlining of the data protection workflow are the primary goals for this solution. This section

will provide 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 13th and 14th Generation

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 1U and 2U

appliances are preconfigured for specific virtualized workloads, and are designed to maintain data availability

in case of node 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

just like a standard hypervisor host as displayed in Figure 1.

Standard hypervisor host.

Technology overview


2.1.1 XC Series 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.

In addition, 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 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.

Technology overview


2.2 Avamar data protection software

Avamar offers deduplication and backup software solutions.

Avamar offers deduplication and backup software solutions, which includes DDBoost software that provides

advanced integration between customer applications and Data Domain backup target systems.

Dell EMC Avamar backup and recovery software with global, source data deduplication delivers fast and

efficient protection for Hyper-V and ESXi environments. Avamar protects VMs by de-duplicating data at the

source, so that only new, unique sub-file variable length data segments are sent during daily full backups.

Deduplication ensures that each unique sub-file object is stored only once on the backup target

Duplicate objects are identified at the client (source)

Only objects that are not already stored on the backup target are sent across the network

Benefits include:

Less backup data

Less network traffic

Eliminating redundant data can significantly shrink storage requirements and improve bandwidth

efficiency

Lowers storage costs as fewer disks are needed

Technology overview


Only new, unique files or data segments are sent during full daily backups.

Key features of Avamar are:

Delivers a software-only data protection solution

Supports VMware vSphere, Microsoft Hyper-V and Azure

Provides in-guest and image-level backup and recovery

Enables application-consistent recovery

Uses variable-length deduplication

Uses AES-256 encryption to secure data in flight or at rest is available by default

Supported backup levels:

Guest Level Backup and Restore

Image Level Backups and Restore

Application level Backup and Restore

2.2.1 Deduplication scenario results In the following scenarios, we are going to show how DDBoost reduces the use of network bandwidth during

backup and reduces the storage space used on Data Domain.

We do this by showing screenshots from EMC Data Domain System Manager for the following scenarios:

Back up a single VM.

Back up same VM with the equivalent of 7 days of activity (14 GiB of random data).

Back up same VM with no changes (same 14 GiB of random data).

Back up a clone of VM with same data (same 14 GiB of random data).

Back up a clone of VM with different data (different 14 GiB of random data).

Technology overview


First, let’s look at the Data Domain statistics before doing any backups.

EMC Data Domain System Manager DD Boost > Storage Units screen

The highlighted values show that nothing was backed up in the last 24 hours.

Technology overview


Next we backed up a single VM.

View of screen after a single VM has been backed up.

Notice that the pre-compression value (200.3 GiB) value is much greater than the post-compression (0.1GiB)

value. This is a savings of 200.2 GiB storage space. The compression is performed before the backup is sent

to Data Domain, so 200.2 GiB of network traffic was also saved.

Technology overview


Next, we added some data to the VM and did the backup again.

View of same VM with an additional 14 GiB of random data after backup.

The pre-compression value shows that this VM was 214 GiB (414.3 GiB minus previously backed up VM of

pre-comp size 214.3 GiB), but only added an additional 0.1 GiB (0.2 GiB minus previously backed up VM of

postcomp size of 0.1GiB) of storage usage. There was also equivalent network traffic savings.

Technology overview


Next, we backed up this same VM again with no changes.

Same VM with no changes is backed up.

The pre-compression value shows that this VM was 202 GiB, but only added an additional 0.1 GiB of storage

usage. There was also equivalent network traffic savings.

Note: We would expect that the pre-compression value would have shown the VM was again 214 GiB, but

operating system activity may have reduced size. Regardless, the amount of data stored and transmitted over

the network was greatly reduced.

Technology overview


Next, we backed up a clone of this VM.

Statistics after a cloned VM is backed up.



Technology overview


Next, we backed up the cloned VM, but we changed the 14 GiB of data to be different from the original VM.

Statistics after a cloned VM with 14 GiB of different random data is backed up



As you can see, DDBoost greatly reduces the network traffic and backup storage usage.

2.2.2 Avamar Virtual Edition (AVE) AVE is a single-node server that runs as a virtual machine using Hyper-V Manager or VMware vCenter. For

this reference architecture, we are using AVE version 7.5 as part of the Dell EMC Data Protection Suite.

Consult a Dell EMC representative for the most up to date version and CPU socket based licensing options.

Technology overview


AVE is not scalable to a multi-node Avamar server and resizing the virtual machine is not supported. You can

increase storage capacity by deploying additional AVE virtual machines and then divide backups among

them. In addition, you can:

Replicate the data to another Avamar server

Delete the smaller virtual machine

Create a larger virtual machine

Replicate the data back to the larger virtual machine

Note: Since we are using AVE with Data Domain, only metadata is stored on AVE. Backed up data is stored

on Data Domain.

2.3 Data Domain backup target

Data Domain systems reduce the amount of disk storage needed

Dell EMC Data Domain systems reduce the amount of disk storage needed to retain and protect data by

ratios of 10-30x and greater. Scale up to 150 PB of logical capacity managed by a single system with DD

Cloud Tier. With throughput up to 68 TB/hour, Data Domain systems make it possible to complete more

backups in less time and provide faster, more reliable restores. The Data Domain Operating System (DD OS)

is the intelligence behind Data Domain systems that makes them the industry’s most reliable and cloud-

enabled protection storage.

Data Domain offers the following in backup and archival of data:

Industry-leading scale and performance

Seamless integration

Reliable access and recovery

Efficient resource usage

Technology overview


2.3.1 Cloud tier Most IT organizations must retain periodic backups for several years. Long term retention (LTR) backup files

are rarely accessed; however, IT must retrieve backups on demand as either full or incremental restores.

Cloud tier integration is facilitated through Data Domain Virtual Edition (DD VE) and/or Data Domain System

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. When used with AVE, the Data Domain cloud

tiering policy is configured via Avamar administrator.

You can also easily leverage DD Cloud Tier in your current Data Domain environment as it can work in

conjunction with all the leading backup and enterprise applications supported by Data Domain. A variety of

public, private and hybrid clouds are also supported, including the Microsoft Azure and Virtustream Storage

Cloud providers.

Data Domain works with a variety of public, private and hybrid cloud solutions.

The Data Domain Cloud Tier ensures that only unique data is sent to and stored in the cloud, and that only

unique data is pulled when data is recalled from the cloud.

Technology overview


Only unique data is moved.

Data moved to the cloud is encrypted and you have the choice to encrypt all data on your Data Domain

system or only the data being sent to the cloud. With DD Retention Lock, you can move files that are locked

on the active tier to the cloud. You can also lock files that are already in the cloud tier.

Choose whether to encrypt all data or only the data moved to the cloud.

Note: For help with deploying this solution, contact Dell EMC Customer Support.

Data protection scenarios


4 Data protection scenarios There are various types of data protection scenarios based on business requirements. The data protection

scenarios, which were validated as part of this solution are listed below.

Validated data protection scenarios

Item Description

Image level backup of VMs Backing up of the VM reflects full backup protection of the VM as well as the applications running in that VM.

Image level recovery of VMs The VMs stored on a Data Domain target are recovered back to an appliance.

Scheduled backup and recovery To backup VMs, use DPMC UI to configure the Avamar backup schedule created by DPMC. At the defined times, this triggers the VM backup. This applies to all VMs on the XC Series cluster(s).

For the initial release of DPMC, use the Avamar UI to restore VMs to the original server or to another server. This addresses several scenarios such as making VMs available on different servers for recovery purpose, moving VMs, or quickly restoring a backup even if the original server is unavailable.

4.1 Configuration of data protection The following sections describe the integration of Dell EMC data protection (DPMC, AVE, Data Domain) with

XC Series clusters. Previous of XC Series clusters is assumed.

4.1.1 Managing Multiple XC Series Clusters with DPMC The following sections are applicable to setting up DPMC and your backup environment for a single cluster or

the first of multiple clusters.

When setting up DPMC to manage multiple clusters, note the following:

Only a single DPMC, a single Prism Central and a single Data Domain are necessary to manage VM

backups for multiple XC Series clusters

DPMC discovers and has the ability to manage all Hyper-V and ESXi clusters registered with the

Prism Central

Managing the backup and recovery scenarios and scheduling is one of the key challenges faced by

customers. DPMC and Avamar make these tasks simple. The key components are:

Best practice recommendations


5 Best practice recommendations

5.1 Data Protection Management Console Use the following best practices for DPMC.

Use a static IP address

Reverse DNS lookup defined

Do not install VMs on SATADOM (13th Generation PowerEdge) or BOSS (14th Generation

PowerEdge)

Have a separate Datastore for Avamar

Have one Avamar instance

Verify ESX and vCenter certificates

Use properly registered certificates from a trusted provider that match DNS names for ESX and

vCenter

Schedule backups during the server’s backup window so that the backups do not overlap with daily

maintenance

5.2 Avamar Virtual Edition (AVE) best practices Use the following list for best practices for AVE.

Use Avamar Administrator to Investigate all failed backups, missing clients, and backups that

completed with exceptions

Protect the Avamar eco system from the Internet by providing full firewall protection

Change all factory default passwords

Enable the Email Home capability

Check the network bandwidth before adding a Data Domain system to an Avamar configuration

Install the Avamar 7.5.0.183 cumulative hotfix 289693

If using Hyper-V, install Hyper-V VSS plugin hotfix 288155 (DPMC will automatically install this hotfix)

Note: For this RA only the metadata is stored on the Avamar Virtual Edition system while the backed-up data

is stored on the Data Domain target server.

Check the Dell EMC Online Support (https://support.EMC.com) for the most current version of the Dell EMC

Avamar Operational Best Practices.

5.2.1 Optimizations for the AVE VM The following factors have the most direct impact on the long-term reliability, availability, and supportability of

the AVE virtual machine:

I/O performance capability of the AVE storage subsystem

Amount of data added daily to the AVE virtual machine (change rate)

Capacity used within the AVE virtual machine

AVE generally performs better when I/O performance is higher, and change rate and used capacity are lower.

To maximize the capacity the AVE virtual machine can use, the daily change rate of the data AVE protects

must be balanced with adequate I/O performance. The first AVE implementation step is to establish which

kind of customer environment AVE will use to protect from either a file server or mixed environment.

https://support.emc.com/



File server environments include file system data

Mixed environments include file system data and structured data (for example, database data).

5.3 Data Domain Virtual Edition (VE) best practices Use the following list for best practices for DD VE.

Dell EMC recommends and supports a thick provisioned storage solution for best performance and

stability for DD VE.

The replication setup for DR is best practice for Data Domain Virtual Edition.

Always use a dedicated datastore for the DD VE system. Sharing a datastore with other virtual

machines may degrade the performance of the DD VE system.

Preferable to use dedicated PowerEdge server to host DD VE.

Data Domain recommends that you enable the performance monitoring features of the DD VE

instance. If you ever need to troubleshoot a DD VE performance problem, you should begin by using

the performance monitoring software to detect and resolve any performance problems on the physical

storage layer.

Note: The DD VE template does not include any storage, so you need to add data disks to the system.

Depending on the amount of disk space, you may need to add memory to the virtual machine. Table 7 shows

the supported storage configurations and their virtual CPU and memory requirements.

Supported storage configurations and their virtual CPU and memory requirements

Virtual Hardware DD VE Configuration

4 TB 8 TB 16TB 32TB 48TB 64TB 96TB

vCPU 2 2 4 4 4 8 8

Memory Size 6GB 8GB 16GB 24GB 36GB 48GB 64GB

CPU At least 1.5GHz per core

System Disks One 250 GB root disk and 10 GB NVRAM disk

NVRAM simulation file size 2GB

Network Card Up to 4 Network Adapters

Storage controller Up to 4 SCSI controllers



5.4 Dell EMC XC Series best practices You can turn on the deduplication feature in XC Series cluster for the container supporting user VMs, but it

must be turned off for the container supporting the AVE VM. Dell EMC recommends that a minimum of two

(2) containers be created for the AVE deployment.

Avamar AVE deployment containers

Container Description

First XC Series container This is where the AVE VM related items are deployed.

Turn off deduplication for this container.

Second XC Series container This is where all the other primary VMs will be deployed: o Infrastructure VMs: DPMC, Prism Central o Application workload VMs

It’s okay to turn on deduplication and any other storage features you would like for this container.

Conclusion


6 Conclusion The solution detailed in this paper shows that Dell EMC XC Series can be integrated with Dell EMC Data

Protection solutions (DPMC, Avamar Virtual Edition and Data Domain) to offer simple, robust backup and

recovery of VMs across both the Microsoft Hyper-V and VMware ESXi hypervisor eco systems. DPMC

provides the ability to monitor data protection environment and define backup policies for VMs and cluster(s).

This paper also references the capability of VMs backed up to Data Domain can then be backed-up to Cloud

Providers (such as Azure and Virtustream) for long-term retention purposes.
