IT teams are struggling as always to meet their backup and recovery objectives; minimize downtime and data loss; ensure that data is always recoverable; and overcome similar pervasive data protection challenges. Often, the inability to adequately protect data or services can delay or prevent deployment of critical applications or services. In a recent trend, businesses report that data protection and the increased use of server virtualization continue to be high-priority IT initiatives.

In the world of digital transformation and distributed environments, data requires tracking and protection to keep up with desired availability as well as security and compliance standards. However, the needs for data protection have changed with the modern digital business as faster and more reliable restoration become top priorities for every business.

 

The answer to these problems is the Hitachi solution for data protection using Hitachi Data Instance Director (HDID) to protect a hyper converged infrastructure using VMware vSAN.

 

HDID provides business-defined data protection so you can modernize, simplify, and unify your operational recovery, disaster recovery, and long-tern retention operations. Data Instance Director provides storage-based protection of the VMware vSphere environment. Data Instance Director provides a modern, holistic approach to data protection, recovery, and retention. It has a unique workflow-based policy engine, presented in a whiteboard-style user interface that helps map copy-data management processes to your business priorities. It includes a wide range of fully integrated hardware storage-based and host-based incremental-forever data capture capabilities that can be combined into complex work flows to automate and simplify copy-data management.

 

Overview

Hitachi Data Instance Director protects hyper-converged infrastructure. This solution uses VMware vStorage API for Data Protection (VMware VADP), a backup option for software-defined storage.

 

In deploying this solution, workload VMs are created on a VMware vSAN datastore. Create the Master virtual machine and Repository virtual machine for Data Instance Director on another VMware vCenter environment.

As part of Data Instance Director backup activity, you back up the workload virtual machines on a repository virtual machine using VMware VADP, a VMware vStorage API that backs up and restores vSphere virtual machines.

Test Results

Below are the HDID Master and HDID repository behavior which is installed and configured on windows server 2012 VM (HA, vMotion, FT). Below are test scenarios for HDID on hyper converged infrastructure using VMware vSAN.

Test steps

Results

1

HDID Master VM HA test

vsphere HA, vMotion Enabled

Start incremental backup from HDID GUI for workload VMs

Backup started

Immediately shutdown the host deployed with HDID Master VM

Back up of workload VMs continues as HDID VM is migrated to another host as part of VMware HA

2

HDID Master VM Migrate (vMotion)

vsphere HA, vMotion Enabled

Start incremental backup from HDID GUI for workload VMs

Backup started

Migrate HDID Master VM from one host to another host

Back up of workload VMs continues as the HDID Master VM is migrated to another host using vMotion

3

HDID Repository VM Migrate (vMotion)

vsphere HA, vMotion Enabled

Start incremental backup from HDID GUI for workload VMs

Backup started

Migrate HDID Master VM

Back up continues as the HDID VM is migrated to another host using vMotion

4

HDID Repository VM HA test

vsphere HA, vMotion Enabled

Start incremental backup from HDID GUI for workload VMs

Backup started

Immediately shutdown host deployed with HDID Repository VM


1. Back up sticks at the point where the host is powered off though HDID Repository gets migrated to another host and powered on automatically
2. After waiting for approx. 15 minutes the backup fails due to resynchronization of vSAN-Cluster' to HDID Repository which is an expected behavior

3. New backup will start on the scheduled time as per HDID policy.

 

 

5

HDID Master VM FT enabled

vsphere HA, vMotion, FT Enabled for HDID Master VM

1. Enable Fault tolerance for HDID Master VM (FT creates secondary HDID Master VM and power-on when primary goes power off)
2.  Start incremental backup from HDID GUI for workload VMs

3. Backup started
4. Immediately power off the host with HDID Master VM


After immediate power off of host, the HDID Master VM is migrated to another host; backup of workload VMs continues  

6

HDID Repository VM FT enabled

vsphere HA, vMotion, FT Enabled for HDID Repository VM

1. Enable Fault tolerance for HDID Repository VM (FT creates secondary HDID Repository VM and power on when primary goes power off)
2.  Start incremental backup from HDID GUI for workload VMs

3. Backup started
4. Immediately power off the host with the HDID Repository VM


After immediate power off of host, the HDID Repository VM is migrated to another host; backup of workload VMs continues

 

Note: HDID backup and restore performance result is between 840Mbps to 876Mbps, i.e. more than 100 MBps
