How to upgrade your Data Domain OS (DDOS)

Recently I was hit with an email indicating that my Data Domain had experienced a file system panic. The end result was a file system reboot during during backups.

After working with support, it was determined that the issue was due to an issue with memory allocation. I was given the below KB regarding my issue.

“DataDomain FS process (ddfs) may crash with memory allocation failures, but available memory still exists: https://support.emc.com/kb/489444

How to: “Space is running low in /ddvar. Please clear space or core dump capability will be disabled.” on Data Domain

“Space is running low in /ddvar. Please clear space or core dump capability will be disabled.”

Today I stumbled upon an interesting issue while prepping for a Data Domain upgrade. The first step taken to prepare for a Data Domain OS upgrade is to reboot the appliance beforehand. This ensures no issues are present before upgrading. If issues are present, they will most likely be brought to light before the upgrade. This is especially important if your system has been up for an extended period of time!

Becoming a vSAN Specialist: Section 3 – vSAN Configuration

VSAN-featured

In this section, I will go over the following objectives found within the VMware vSAN Specialist Blueprint: Objective 3.1 – Identify physical network requirements

Objective 3.1 – Identify physical network requirements

Let’s start with the network basics.

  1. Dedicated network port for vSAN traffic
  2. 10GB (dedicated or shared) highly recommended, required for all flash deployments) <1ms latency
  3. 1GB dedicated for hybrid setups. Real work environments would suffer with 1GB (Minus ROBO) <1ms latency
  4. vSAN VMkernal port required for each ESXi host, even if it isn’t contributing storage
  5. ESXi hosts within a vSAN cluster must all utilize Layer 2/3 upstream

Becoming a vSAN Specialist: Section 2 – vSAN Fundamentals

VSAN-featured

In this section, I will go over the following objectives found within the VMware vSAN Specialist Blueprint: Section 2 – vSAN Fundamentals

Objective 2.1 – Provide a high-level description of vSAN

Introduction to vSAN

vSAN is an enterprise-class software storage solution built directly into the VMware platform. It runs on commodity hardware (x86) or vSAN Ready nodes.  What does this mean? Instead of having a separate software solution controlling the storage, the actual ESXi hosts alongside with vSphere have the vSAN technology (Software Defined Storage) built directly into the kernel/software. This software then utilizes the commodity hardware (compute, storage, network) within the host/appliance to create the perfect marriage of virtualization and software defined storage. It utilizes storage policies to intelligently place VM objects on underlying local storage. This is the special sauce that makes vSAN so great. It automates storage on many levels, which in turn leads to significant simplification with regards to how storage is provisioned and managed.

Why is this important? Instead of having to buy separate software, you can utilize this software since it’s already a part of vSphere. This in combination with local disk installed within x86 hardware makes the vSAN solution a truly modern and software defined solution. This reduces costs and complexity.

Becoming a vSAN Specialist: Section 1 – Storage Fundamentals

VSAN-featured

In this section, I will go over the following objectives found within the VMware vSAN Specialist Blueprint: Section 1- Storage Fundamentals

Objective 1.1 – Identify storage device characteristics

vSAN is very similar to today’s traditional storage technologies; however, there are some key differences and unique configurations vSAN utilizes to make it the technology it is today. Here are some of the storage device characteristics that make vSAN hum. These are also requirements in order to use vSAN. Be sure to check out the HCL for vSAN, as it’s the TRUTH and should always be followed to ensure success!
