PowerProtect Data Domain All-Flash Ready Node

This health check tool is designed to triage common and performance issues reported for DDVE system.

This document highlights minimum, recommended, and latest code versions for Dell Technologies Enterprise and Data Center Infrastructure products. Dell carefully evaluates and monitors code deployment data to ensure that product releases meet our stringent expectations to provide our customers with reliable products and solutions.

This article answers common questions about Data Domain licensing, including electronic licensing (ELMS), license management, and deployment using Software License Central.

Data Domain sysadmin/SO password resets no longer require Support intervention when running DDOS (7.10.1.40 or newer). A password reset token is sent to the registered email address. Copy the token to a supported USB drive, insert it into the system, and log in as sysadmin or security officer to reset the password.

DDoS 8.7 introduces a check that triggers a warning alert when file replication is configured with anonymous authentication, encouraging the use of stronger authentication methods for improved security.

After modifying the connection host, the Data Domain (DD) UI may incorrectly display replication context errors even though replication is properly configured and functioning. This is a known UI bug and does not impact replication operations.

Considerations when doing a storage migration to 8TB packs with OP

DD enforces stricter FEC validation during interface configuration; errors originate from DD, not Cyber Recovery (CR). CR (by 'securecopyanalyze') only triggers validation, while DDOS enforces it. FEC is unsupported on some Intel NICs (for example, X710-T4L), so code must ignore registry FEC settings.

This article provides download links and status information for current PowerProtect Data Domain Operating System (DDOS) releases, including feature and Long‑Term Support (LTS) versions. It also outlines upgrade considerations, documentation references, and supported platforms.

This article describes how to migrate AWS Elastic Block Store (EBS) volume from gp2 to gp3 type for Data Domain Virtual Edition (DDVE) appliance deployed in the AWS cloud platform.

Dell PowerProtect Data Domain remediation is available for multiple security vulnerabilities that could be exploited by malicious users to compromise the affected system.

This article describes how to troubleshoot memory-related alerts on Dell Data Domain systems, including how to identify a faulty DIMM that requires replacement. It covers common alert codes, root causes of correctable and uncorrectable ECC errors, and step-by-step resolution guidance such as initiating POST-Package Repair (PPR), running diagnostic CLI commands, and performing physical troubleshooting.

Prediction Enabled Automatic Cleaning is run only when its prediction engine determines whether used capacity exceeds a configured percentage within a configured time.

How to rename the hostname (ha-name) of high availability (HA) systems

BoostFS processes may consume excessive physical memory over time, particularly in environments with multiple mounts. This can lead to increased overall system memory usage and degraded system performance.

A boot-time issue may occur on systems using Intel X710 network adapters where network interfaces are not correctly detected during system startup. This happens when network cables or SFPs are connected during power-on, leading to incorrect NIC enumeration by system firmware before the operating system loads.

This article identifies the commands and steps required to configure Cloud Tier or otherwise known as Long Term Retention (LTR) on Data Domain systems running Data Domain Operating System (DDOS) 6.0 and later versions.

DD Management Center is not able to retrieve current data from the managed system. Information reported on DD Management Center may not reflect the current status of managed system.

To upgrade Data Domain appliances with additional storage tiers, such as Cloud Tier (LTR), Extended Retention, or Cache Tier, minimum platform hardware requirements must be met, prior to installing licenses or allocating capacity to a new tier. When required hardware or licenses are missing or misconfigured, the license for the feature cannot be installed or the creation or expansion of a tier is blocked.

Data Domain Virtual Edition (DDVE) system upgrade fails with filesystem shutdown error.

When a vault Data Domain fills up, symptoms include high capacity usage, poor deduplication, and expiration failures. The root cause is inadequate capacity planning, improper backup configuration, and unchecked saveset accumulation across DD, NetWorker, Avamar, and Cyber Recovery.

This article provides a clear, model‑by‑model breakdown of the recommended BIOS and iDRAC firmware versions for each supported DDOS release across the DD series platforms. It is designed to help you quickly confirm which firmware levels align with your system’s DDOS version, reduce compatibility issues, and ensure that your environment stays stable, secure, and fully supported. Use the tables below to find the right BIOS and iDRAC versions for your specific DD model in seconds.

This article describes how to change cloud profile from STANDARD to STANDARD-IA Storage Class and how to convert existing objects in AWS cloud tier bucket from STANDARD to STANDARD-IA Storage Class.

Data Domain Operating System (DDOS) 8.4 introduced a system health check feature. When checking cloud health, it may incorrectly report an issue connecting to the cloud endpoint port.

The Data Domain appearing as "red" in the Avamar User Interface (AUI) or Avamar Administrator console can be caused by several different issues. This guide provides a structured troubleshooting path and directs to relevant articles for diagnosing and resolving these conditions.

After a disk replacement, the new disk information is not updated on the Data Domain Operating System (DDOS), and the alert remains.

This article explains an issue with the Data Domain Virtual Edition (DDVE) system recovery function caused by a different encryption key format between the old and new systems.

Data Domain systems automatically monitor for hardware, software, and environmental conditions that may require service. When certain alerts occur, the system can automatically open a Dial Home Service Request (SR), either immediately or after a short monitoring period. This proactive SR creation ensures timely support while reducing unnecessary or duplicate cases.

When the https or "ca trusted-ca" certificate expires on a Data Domain, it causes issues when trying to access the web UI. Generating a new certificate resolves the issue.
