This section provides guidance on data protection and file workloads.
As the adoption of VDI has grown, this growth 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 Data Protection for Converged Infrastructure simplifies backup, recovery, and failover of your VxBlock 1000. Dell EMC offers the most advanced data deduplication, replication, and data protection technologies for achieving your RPO and RTO requirements. For a detailed listing of the data protection products that are available for VxBlock 1000, see the VxBlock 1000 Converged Infrastructure datasheet.
Dell EMC provides several 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 so is ideal for the VDI use case. AVE 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. For additional information, see Dell EMC Avamar Virtual Edition Data Protection Software.
Data Domain Virtual Edition
Dell EMC Data Domain Virtual Edition (DDVE) is a data protection storage solution that runs as a virtual appliance on a customer's choice of hardware or on various public cloud options, including VMware Cloud on AWS. For on-premises deployments, DDVE is deployed as a virtual appliance on the relevant hardware platform. 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. For additional information, see Dell EMC Data Domain Virtual Edition.
Other Dell EMC data protection products
Dell EMC provides several other data protection products for specific use cases. Products include a range of appliances that reduce data protection complexity. These scalable, preconfigured solutions combine data protection storage with software, search, and analytics. For additional information, see 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.
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.
