New features in RecoverPoint 5.0

DellEMC just released RecoverPoint 5.0. Listed below are the new features that you can find in the release notes of RecoverPoint 5.0.

Remove volume from a consistency group without journal loss

Volumes can now be removed from a consistency group without incurring journal loss. Adding volumes to a consistency group that are larger than the capacity of the journal will no longer cause the system to enter one-phase distribution mode.

Dynamic network interface assignment

This feature allows the user to select various network topologies that combine different traffic types (for instance, LAN and WAN) on the same network adapter. Reducing the number of ports reduces the number of IP addresses that need to be configured and alleviates some restrictions on network configuration (for instance, LAN and WAN will not necessarily have to be on different subnets). The user may also choose to have each traffic type on a dedicated network adapter as before.

Dynamic IP configuration

RecoverPoint 5.0 introduces the option of automatically assigning all RecoverPoint IP addresses except the cluster management IP address using the network DHCP server. This significantly reduces the work of installing a new RecoverPoint RPA cluster.

XtremIO enhancements

XtremIO enhancements include:

  • One to three consolidation policies can now be specified for each copy of a consistency group that resides on an XtremIO array.
  • XtremIO copy volumes can now be expanded on storage without triggering a pause in replication for the whole consistency group. In RecoverPoint 5.0, when a replication set is expanded on storage, RecoverPoint automatically re-configures the replication set to protect the expanded areas and updates the volume size.
  • Snapshot consolidation has been simplified and it can be customized through Unisphere for RecoverPoint as well as the CLI.
  • Dynamic LUN resizing.

ProtectPoint 3.5 partial recovery

When using RecoverPoint 5.0 with ProtectPoint 3.5 and later, specific volumes of a consistency group can be selected for production recovery, while others volumes in the group are not recovered.

Gen6 Hardware diagnostics

RecoverPoint 5.0 introduces error messages that identify a faulty fan or power supply on Gen6 hardware. These error messages allow replacing only the faulty unit.

Support for new event types

RecoverPoint release 5.0 generates events for arrays.

Language packs

Users no longer need to download and install the Unisphere for RecoverPoint language packs from the EMC Online Support site. The RecoverPoint 5.0 language packs are now built-into the product.


Serviceability improvements include:

  • The ability to collect partial system information specified by the user
  • Reducing the size of collected system information
  • A Change Management file that is older than 30 days prevents installation/upgrade and facilitates downloading an updated file
  • System Reports (SyR) mechanism identifies the product type (physical or virtual) and tracks first installation date and time
  • Users can specify the RPAs from which to collect logs
  • Downloading collected logs from a browser when the RPA is detached
  • Not forcing users to provide FTP server information when collecting logs from a detached RPA
  • Customer procedures on Solve Desktop are now customer viewable: Solve Desktop gathers critical information from EMC product guides to generate a concise procedure document.

Unity VSA NAS Replication

We will cover the replication of a NAS Server within a UnityVSA Deployment.  Listed below are the prereqs:

  • Unity VSA deployed as a source and a target
  • Storage Pools created at Source and Target
  • NAS server deployed at Source

Creating a Replication Interface

The first step in the process is creating replication interfaces at both the Source and Target Unity VSA systems.

Go to the Data Protection section and select Replication.  Under the Interface tab, create a new interface.


Specify your replication interface, IP address, Subnet, Gateway and VLAN ID if necessary


The replication interface will then be created


Verify the Replication Interface.  Create the Replication Interface at the Source and Target


Replication Connections

One you have created your Replication Interfaces you should create the Replication Connection to your Target Unity VSA. Go to the Connections tab under Data Protection, Replication and create the connection.


Put in your information of your target system.  Management IP, User Name, Password, Local System admin password and connection Mode.


The connection process will begin


Once the connection has showed up you may have to Verify and Update


Once the Connection is successful you will have a green check.


Replicating NAS Servers

Once you have created your Replication Connection to your target it’s now time to replicate your NAS Servers

Go to Storage, File and select the NAS Servers Tab.  Select the Properties of the NAS Server you need to replicate.


Go to the Replication tab and Configure Replication


Provide the Replication Mode and RPO


Configure the Destination NAS Server. Specify Name, Storage Pool, and SP.  The associated File Systems will show up as they will be replicated as well.


Summary of the replication


Replication session will be created.


Verify successful Session Creation


The Replication Tab will now show the active Replication status of the NAS Server.


Under the session tab the status of the NAS Server as well as the File System will be listed.


The next blog in this series will cover NAS Server failover.

New Beginnings at RoundTower Technologies!

On 8/8 I took the position of Senior Systems Engineer at RoundTower Technologies.  I will continue implementing storage solutions as well as adding new skills involving Isilon, Data Protection, and getting into the full Data Center stack.

I look forward to what RoundTower has to bring in the area that I have grown my career, The Carolina’s.  On this day EMC is referring to “A New Dawn” I wanted to share this information.

My blog will pick back up with more Unity as well as some new categories like Unisphere Central and Isilon.  I will also be attending Dell World in October and look forward to sharing my thoughts there as well.

Unity VSA Storage Pool Creation

Once you have deployed Unity VSA, as covered in the previous blog, you will need to create a storage pool if you want to serve out any storage.  I have listed the steps below.

Under the Storage Pool Section go to Pools. Select the + to start the “Create Pool Wizard”


Name the Pool


Assign a Tier to each Virtual Disk attached to the VSA. You have Extreme, Performance and Capacity.


Select the Tiers you want in the Pool


Select the Virtual Disk you want to add that are in the tiers you selected


Specify if you want to create a VMware Capability Profile for the Pool. This is needed for VVOLS.




The results of the pool creation will be displayed


Summary of the Pool Created


I will cover creating a NAS Server in my next post and then go into NFS creation and replication.

Unity VSA Deployment

Unity VSA Deployment

EMC released the new mid-range storage array “Unity” at EMC World this year.  There are 3 different options: Unity All Flash, Unity Hybrid Flash and UnityVSA.  The Unity VSA platform can scale up to 50TB and can be fully unified.  The UnityVSA Community edition allows up to 4TB of capacity for free!  Below are the step on how to deploy Unity VSA:

System Requirements:

  • vCenter 5.5 update and later.
  • ESXi 5.x and later
  • 12GB Memory
  • 2 vCPU
  • 4TB Usable Capacity for the Community edition
  • UnityVSA OVA can be downloaded from the EMC Support site

Deploying UnityVSA OVF

Right Click on the host you want VSA to run on and select “Deploy OVF Template”


Select the OVA you downloaded



Review the details and “Accept extra configuration options”


Name the VSA and select a folder


Specify the Storage.


Setup the networks. There will be a management port and Data Network Ports


Customize the template. Specify the System Name, IPv4 Management and IPv6.  Leave the IPs blank if you want to use DHCP.


Review and Deploy


Once the OVA is deployed add some VMDKs that you want to use for storage in the VSA by editing the settings.  Once you power on it can take up to 15 minutes for UnityVSA to be up and running.


Initial Configuration Wizard

Once the VSA is up and running start the Initial Configuration by going to the Management IP and using the default admin credentials


Accept the Copyright


Set the new admin and service account passwords. They can be set to the same.


License the VSA by using the System UUID identified


Go to the following site and use the System UUID to create the license


Once you have the license browse to it and upload


Verify License installed






You have the options of creating Pools or doing this at another time


Setup Email and SMTP


Create any iSCSI Network interfaces. This can be done later


Create any NAS Servers. This can be done later.


At this Point the Initial Configuration is complete!


Go forth and enjoy UnityVSA!!


I plan on doing several more blogs on UnityVSA including NAS Servers, NFS Shares and replication.  Stay tuned!
