As the adoption of VDI has grown, this has resulted in an elevation of the strategic importance of organizational VDI environments: users who are critical to business success are increasingly using VDI for their day-to-day productivity tasks. Consequently, the importance of protecting the VDI environment and the business value of its data has also grown as customers seek to ensure that their VDI environments meet corporate availability, recovery time objective (RTO), and recovery point objective (RPO) requirements.
Dell EMC provides a number of data protection solutions for different data protection requirements.
Dell EMC Avamar Virtual Edition
Dell EMC Avamar Virtual Edition (AVE) is a data protection solution that delivers software-only data protection for virtualized environments and is therefore ideal for the VDI use case. AVE is a fully-featured data protection solution that is deployed as a virtual appliance and supports advanced functionality such as backup in the cloud (including VMware Cloud on AWS), change block tracking (for fast backup and recovery) and integration with multiple VMware interfaces, such as the vRealize Automation Data Protection Extension. Further information on AVE is available at the Dell EMC Avamar Virtual Edition web page.
Data Domain Virtual Edition
Dell EMC Data Protection Virtual Edition (DDVE) is a data protection storage solution that runs as a virtual appliance on a customer's choice of hardware or any of multiple public cloud options (including VMware Cloud on AWS). For on-premises deployments, DDVE is deployed as a virtual appliance on the relevant hardware platform, in this case the Dell EMC XC Family. DDVE has a single point of management with Dell EMC Data Domain Management Center and scales up to 96 TB per instance. One of the key features of the DD storage protection solution is DD Boost, which provides advanced integration with data protection applications such as AVE to enable client-side deduplication, thus accelerating backup. Further information about DDVE is available at the Dell EMC Data Domain Virtual Edition webpage.
The process for protecting a VMware Horizon VDI environment using AVE and DDVE is outlined in the Data Protection of a VMware Horizon VDI Environment using Dell EMC Data Protection operations guide.
Other Dell EMC Data Protection Products
As well as the DDVE and AVE solutions described in the preceding sections, Dell EMC provides a number of other data protection products for specific use cases, including a range of appliances which reduce the complexity of data protection with a scalable, pre-configured solution that combines data protection storage with software, search and analytics. Further information is available at Dell EMC Data Protection.
The increased growth in the amount of data that is stored in file shares and user home directories across IT environments in recent years has resulted in an increased focus on the need to better manage this unstructured data. As a result, many organizations are choosing to deploy dedicated file workload solutions with capabilities such as cloud file tiering and single file system namespaces across their IT infrastructure, including for file workloads in a VDI environment.
Dell EMC provides a number of solutions for different types of file workloads.
The architectures that are shown in Figures 5 and 6 below show VDI management and compute environments sharing a vSphere HA cluster. This architecture is universally applicable across SDS environments that require access to dedicated file storage. It is also acceptable to configure these management and compute environments in separate HA clusters (see Architecture overview). In this scenario, each compute cluster and its associated management cluster should share a single file storage system, for example Unity, Isilon.
Dell EMC Unity storage is simple, unified all-flash and hybrid storage with hybrid cloud capabilities.
Dell EMC Unity is ideal for general-purpose NAS/SAN mixed workload consolidation, smaller file workloads (including small to midsized VDI environments), and transactional databases.
The following figure shows an example of a 5,000-user VDI deployment using Dell EMC Unity storage for file shares.
When deploying Dell EMC Unity in a VDI environment, Dell EMC recommends that you deploy a separate Dell EMC Unity storage system with a vSphere HA cluster or Block. This structure provides the greatest scalability, resiliency, and flexibility when deploying and maintaining file services for the overall user pod. As unstructured data storage needs grow over time, the capacity of each Dell EMC Unity storage system can be scaled up independently with minimal user impact. You have the choice to deploy alternative architectures to the one suggested here, but you should carefully consider the tradeoffs.
For guidance about selecting an appropriate Dell EMC Unity storage solution for your file workload requirements, see Dell EMC Unity XT All-Flash Unified Storage.
Dell EMC Isilon storage is the industry's number one scale-out NAS solution for any file workload.
Isilon is ideal for a wide range of file workloads (including large-scale enterprise VDI environments requiring a single file system namespace), high-performance computing (HPC), archiving, and infrastructure consolidation.
The following figure shows an example of a 20,000-user VDI deployment using DeIl EMC Isilon scale-out storage with a single namespace.
When deploying Isilon in a VDI environment, Dell EMC recommends that you deploy a separate Isilon storage system with a vSphere HA cluster or Block. This structure provides the greatest scalability, resiliency, and flexibility for deploying and maintaining file services for the overall user pod. As unstructured data-storage needs grow over time, you can scale up the capacity of each Isilon storage system independently with minimal user impact. In addition to scaling up each Isilon chassis, Isilon can also be scaled out using the OneFS operating system. This ability means that additional Isilon systems can be added to provide a single volume and namespace that all user pods in a data center can access.
As shown in the previous figure, you can scale out the system as the VDI environment grows. You can deploy alternative architectures to the one suggested here, but first consider the tradeoffs carefully.
For guidance about selecting an appropriate Isilon storage solution for your file workload requirements, see Dell EMC Isilon Scale-Out Network Attached Storage.
Enterprise equipment requires power to operate, racks to enable streamlined management, and cooling to maintain reliable operations.
Careful selection of the infrastructure solutions that provide these capabilities is vital to ensure uptime, scalability, energy efficiency and ease of management. Dell EMC provides a wide range of Data Center Infrastructure solutions:
