Introducing DDVEIntroducing DDVEDD Virtual Edition (DDVE) is a software-only protection storage appliance: a virtual deduplicationappliance that provides data protection for entry, enterprise and service provider environments.Like any DD system, DDVE is always paired with backup software.DDVE runs the DD Operating System (DD OS), and includes the DD System Manager graphicaluser interface (GUI) and the DD OS command line interface (CLI) for performing systemoperations.DDVE includes the following features:lHigh-speed, variable length deduplication for a 10 to 30 times reduction in storagerequirementslUnparalleled data integrity to ensure reliable recovery, and seamless integration with leadingbackup and archiving applicationslDD Boost to speed backups by 50 percentlDD Encryption for enhanced security of datalDD Replicator for network efficient replication that enables faster time-to-DR readinessDDVE runs on two types of platforms:lOn premises, DDVE supports VMware, Hyper-V, KVM, and VxRail.lIn the cloud, DDVE also runs in the Amazon Web Services (AWS) (cloud and gov cloud), Azure(cloud and gov cloud), VMware Cloud (VMC) on AWS cloud platforms, and Google CloudPlatform (GCP).For more information about the features and capabilities of DD systems (both physical and virtual),see the DD Operating System Administration Guide.DDVE featuresResource configurations depend on your DDVE configuration.

Deploying DDVEManaging DDVEUse the VMware vSphere client software, the VMware vSphere Web client, or Hyper-V Managerto install a DDVE instance and define its virtual hardware, including CPUs, memory, networkinterfaces, and virtual disks.The DD System Manager provides a configuration wizard to guide you through the steps requiredto configure DD OS after the virtual appliance is installed.Once DDVE is configured and running, you can access the system console to run DD OScommands by using the VMware vSphere Web client or Hyper-V Manager. You can also administerthe DDVE by using a terminal emulator or ssh command to use the CLI.The default login credentials for the DDVE instance are:lUsername: sysadminlPassword: changeme or the password specified during deploymentNote: The system sends an alert if an RSA DPM client certificate is within 15 days of expiring.Supported virtual environmentsDDVE is supported in the following virtual environments:lMicrosoft Windows Server 2012 R2 with Hyper-V.lKVM hypervisor on supported Linux distributionslVMware ESXi servers, either standalone or managed by VMware vCenter, versions 5.5, 6.0,and 6.5 with the corresponding versions of the VMware vSphere client application.Note: DDVE supports virtual hardware versions of virtual machines up to the latest version ofthe ESXi in use, and minimum of version 10. Consult VMware latest documentation for anyvirtual hardware version upgrades.Table 2 Supported Virtual HardwareESXi VersionUp to Virtual Hardware versionESXi 6.513ESXi 6.011ESXi 5.510Note: The OpenVMTools are pre-installed on the DDVE image. When you update the DD OSsoftware on the DDVE from within the DD OS environment, any necessary updates to theOpenVMTools are installed automatically. It is not possible to update OpenVMTools on thevirtual machine from outside DD OS.The hypervisor user needs read-only privileges on the data center object where the server orcluster hosting the DDVE instance resides.For information about compatibility with VMware or Microsoft products, visit the support portal athttps://support.emc.com.Provisioning physical storageYou can provision storage on an ESXi or Windows Hyper-V server to host the DDVE instance.14PowerProtect DD Virtual Edition on Premises Installation and Administration Guide

Deploying DDVENote: Ensure that the disks provisioned in VMware are configured as "Independent PersistentDisks."Raw physical storage capacity requirementsThe following table shows the raw storage capacity required to provide the net usable capacity.For raw capacities not listed, use the same raw capacity in TiB as the usable capacity.For example:lTo net 40 TB usable capacity, provision 40 TiB.lFor 5 TB capacity with 8 TB configuration, provision 5 TiB.Note: The capacity in vCenter or Hyper-V manager is listed in TiB. When you create a 1 TBvirtual disk in vCenter, a storage capacity of 1 TiB is allocated.This table does not apply to configurations with DD Cloud Tier.Table 3 Raw physical capacity requirementsUsable Capacity (TB)Raw Capacity (GiB) at each 921692169216Table 4 Conversions for raw physical capacityGiBTB10.001074TBTiB10.909495Managing SSD cache tiersThe SSD cache tier for DDVE systems uses flash technology to create cache tiers for file systemmetadata. The SSD cache is a low latency, high input/output operations per second (IOPS) cacheto accelerate metadata and data access.Note: The minimum software version required for HyperV and KVM is DD OS 6.2.x.x.PowerProtect DD Virtual Edition on Premises Installation and Administration Guide15

Deploying DDVEThe SSD cache tier provides the SSD cache storage for the file system. Caching the file systemmetadata on SSDs improves I/O performance for both traditional and random workloads.When the cache tier is first created, a file system restart is required if the cache tier is added whenthe file system is running. You can add cache to a live system without disabling the file system. Ifthe file system does not been exist or if the file system is not enabled, creating or enabling the filesystem after adding the cache tier activates the SSD cache.Note:lIf encryption is enabled for the active tier, data cache and DM cache are not enabled.lWhen the remaining number of spare blocks gets close to zero, the SSD enters a read-onlycondition. DD OS treats the drive as read-only cache and sends an alert.SSD cache tier requirementsReview the SSD requirements for your specific DDVE model. Note that SSD cache tier is notsupported for configurations less than 16 TB.Table 5 Supported SSD models and requirementsDDVE ModelSSD RequirementDDVE 16 TB160 GBDDVE 32 TB320 GBDDVE 48 TB480 GBDDVE 64 TB640 GBDDVE 96 TB960 GBBest practices and limitations for cache tier storageYou should be aware of the following best practices and limitations when adding storage to thecache tier:lAdding storage to the cache tier requires a CAPACITY license in the system.lAdd only SSD type disks to the cache tier. If the device is not recognized as an SSD disk, usethe force option in the storage add tier cache CLI command. For example, storageadd tier cache dev force.lYou must add at least a 100 GB disk to the cache tier.lIf the tier is under provisioned when the file system is enabled, you must add the requiredcache capacity.lIf the tier is over provisioned, adding the cache tier storage fails.SSD cache tier considerationsBe aware of the following best practices and limitations for SSD cache tiers:16lWhen the number of spare blocks remaining gets close to zero, the SSD enters a read-onlycondition and DD OS treats the drive as read-only cache and sends an alert.lWhen SSDs are deployed within a controller, the SSDs are treated as internal root drives. Theyappear as enclosure 1 in the output of the storage show all command.PowerProtect DD Virtual Edition on Premises Installation and Administration Guide
