IntroductionVirtualization is widely adopted in the IT industry to simplify IT operations and allow ITorganizations to respond faster to changing business demands. The IT industry has witnessed agrowth trend in virtualization infrastructure. Vendors such as VMware and Microsoft Hyper-V arethe key players in this space.EMC Avamar is tightly integrated with VMware and Microsoft Hyper-v which in turn havewidened the data protection space for virtual infrastructures and provided flexibility forcustomers to use the Avamar data protection solution for their virtualized IT infrastructure.Why data protection for virtual infrastructure?Exponential data growth, regulatory requirements, and 24X7 availability have all increased thedifficulty in completing both virtual and physical backups successfully within shrinking backupwindows. In virtual environments, storage challenges are exacerbated due to virtual serversprawl that virtualization almost inevitably brings, creating hundreds of duplicate server and/ordesktop images. Virtual server consolidation further adds to the backup window problem.Improving backup operations and reducing storage costs involved in server virtualization arekey to successful expansion of virtualization across an organization. Leveraging deduplication invirtualized environments can address not only the pain points and barriers to expansion, but canalso offer a strong return on investment (ROI) and significantly reduce the total cost ofownership (TCO) of virtual infrastructure data protection.EMC Avamar solution to address data protection challenges of virtual infrastructureEMC Avamar integration with VMware, Hyper-V, and Data Domain provides a complete dataprotection solution for virtual infrastructure. Combination of all of the following provides the dataprotection solution to virtualized data centers and cloud infrastructure.1. Data protection solution for VMWare2. Data protection for Hyper-V3. Avamar virtual edition4. Avamar integration with Data Domain5. Data protection for Azure cloud2015 EMC Proven Professional Knowledge Sharing4

Why choose Avamar for virtual infrastructure?Avamar software quickly and efficiently protects virtualized infrastructure environments by usingagents on the virtual machines or virtual storage hypervisor to reduce the size of backup datawithin and across virtual machines. For virtual machine backups, Avamar eliminates traditionalbackup bottlenecks caused by the large amount of redundant data that must pass through thesame set of shared resources, i.e. the physical server's CPU, Ethernet adapter, memory, anddisk storage.Capabilities of Avamar Up to 10X faster daily full backups Up to 95 percent reduction in required global backup storage media Up to 99 percent reduction in required daily network bandwidth Encryption of backup data in flight and at rest Scalable grid architecture Daily server integrity and data recoverability checks Simple one-step recovery Flexible deployment options, including EMC Avamar Data Store and EMC AvamarVirtual Edition for VMware and Hyper-V (a virtual appliance)Avamar Virtual EditionAvamar Virtual Edition (AVE) is a single-node Avamar server that runs as a virtual machine onVMware ESX or Microsoft Hyper-V. AVE is similar to existing single-node Avamar backup andrecovery software providing fast daily full backups by deduplicating the data at the client toeliminate backup bottlenecks caused by constrained or shared infrastructure and networks.Thus, AVE is an ideal data protection solution for small, medium, or remote offices that havestandardized on virtual infrastructure.Benefits of AVE Rapid, cost-effective deployment. Simplified management by virtualizing all aspects of the backup and recoveryoffering. Lower cost by leveraging shared server and storage infrastructure. Replication in virtual environments as well as between virtual and physical. Rapid return on investment.2015 EMC Proven Professional Knowledge Sharing5

Starting with Avamar 7.0, each Avamar Virtual Edition supports up to 4TB of licenseddisk storage capacity provisioned to a virtual machine on a VMware and Hyper-V. Othercapacities are available: 500GB, 1TB, and 2TB.Choosing the right hypervisor for AVEVMware and Hyper-V are highly efficient and both support almost the same functionality withrespect to Avamar data protection functionality. Thus, before implementing or recommending aAVE- based data protection solution, it is important to do an in-depth performance analysis onthe virtual infrastructure to support the business requirement. AVE system performance benchmarking test AVE backup/restore benchmarking testAVE system performance benchmarkingAVE system performance testing should be done to analyze the storage I/O subsystem toensure that AVE can function at an acceptable level in the virtual environment. Avamar AVE hasrecommended throughput levels for each AVE configuration. Example:.5TB AVE : 400 seeks/sec1TB/2TB/4TB AVE : 500 seeks/secAnalysisTotal seek throughput of AVE on Hyper-V is not in the acceptable range, so storage subsystemcompatibility with Hyper-V needs to be checked and improved before implementation.2015 EMC Proven Professional Knowledge Sharing6

AVE backup/restore benchmarkingThis type of backup/restore performance analysis provides some indicative information onchoosing the right hypervisor solution for AVE. The performance results will vary depending onthe backup data size, data type, application type and number of parallel backup, etc.Note: Following table shows some sample data for example purpose onlyIn this table, the AVE configuration and data type is the same in both Hyper-V & VMware.Take away points from this analysis from the above table is:1. Backup performance of AVE on Hyper-V is better than AVE on ESX2. Restore performance of AVE on ESX is better than AVE on Hyper-V3. HFSCHECK performance of AVE on Hyper-V is better than AVE on ESX4. Garbage collection performance of AVE on Hyper-V is better than AVE onESX.(meaning the maintenance window of ESX will be more than Hyper-V)Conclusion with this analysis In this infrastructure, Hyper-V is the preferred option for faster backup and lowermaintenance window.2015 EMC Proven Professional Knowledge Sharing7

In this infrastructure, VMware ESX is the preferred option for cases where data restorefrequency is high. Also, ESX would be the preferred option for replication source.Recommendation on AVE configurationThe decision on AVE size should be determined according to the business requirement. .5TB/1TB AVE can be an ideal option where Data Domain is the preferred storage andAvamar will be used primarily for policy and management. 2TB/4TB AVE can be an ideal option for small business units where the rate of datagrowth rate is minimal and Hypervisor local storage is the preferred storage option. Thisis a cost-effective solution.Avamar Integration with Hyper-VTraditional data protection challengesHyper-V virtualization technology has brought us a number of benefits, such as faster virtualserver deployment and easier management. When looking to protect these new rapidly growingserver implementations, traditional backup methods become a challenge.Business opportunity for Avamar with Hyper-V:As per recent market analysis, MS Hyper-V holds 30.6% (vs VMware 46.4%) market share inthe private cloud space. Looking at Hyper-V market share, there is a big opportunity for EMC tosell Avamar as a data protection solution for customers that have Hyper-V virtual infrastructure.How Avamar works with Hyper-VThere
