Creating Volumes, Initiator Groups and Mapping them in XtremIO 4.0

EMC has recently released XtremIO 4.0 and with that comes an interface change under the configuration tab.  This blog will show you the new look interface and how to create Volumes, Initiator Groups, and how to map them together.

Configuration Tab

As you can see the Configuration Layout has changed.  This new look provides more detail when it comes to Volumes, Consistency Groups, Snapshots, Initiator Groups, Initiators and Schedules.


Creating a Volume

You have 2 ways to create a volume shown below.  Either right-click Volumes or use the Create Volume button.


Specify the Volume parameters such as size, Logical Blocks, IO Alerts and VAAI Alerts (Recommended).  You can also add multiple volumes at the same time by select “Add Multiple” on the right side.


Specify Number of Volumes, Name, Start Index, Size, Logical Blocks, IO Alerts and VAAI Alerts


Manage the Volume Tags by either selecting an existing one or creating one by selecting “Create Tag” at the end


Give the Tag a name and decide what object the Tag should be defined under


Once you have selected your tag click “Finish”.  The Volume will now show up under the Volume Tab


Initiator Group Creation

You have 2 ways to create an Initiator Group shown below.  Either right-click Initiator Groups or use the Create Initiator Group button.


Specify Initiator Group Name then select “Add” to add the initiator.


Add the Initiators for the Initiator Group.  Name each initiator and specify OS Type


Create and apply any Initiator Group Tags if needed


The Initiator Group will now show up.  Verify Zoning and Connectivity by going to the Targets Tab and looking at the FC1 and FC2 connections for green check marks.



Mapping Volumes to Initiators

Go to the Volumes Section and select the Volumes you want to Map. You can Right Click the Volumes or select “Create/Modify Mapping”


Select the Initiator Groups that you want to map


Specify a Volume ID and then Finish


Select the Mapping Tab to see what Volumes are mapped to the Initiator Group


At this point you can add your storage to your hosts.

RecoverPoint for VMs 4.3 – New Features and Changes

RecoverPoint for VMs 4.3 has been released with a lot of new features and changes.  This blog will outline all of them with the hope of doing some demos in the future.

Multi-cluster support

RecoverPoint for VMs 4.3 now supports up to three copies (including the production copy) per consistency group and up to three vRPA clusters per RecoverPoint for VMs system, enabling concurrent local and remote replication.

VC licensing

RecoverPoint for VMs licenses are now per vCenter Server (as opposed to per vRPA cluster), enabling multiple vRPA clusters connected to a single vCenter Server to share the same license.

Deployment Automation with REST API

Enterprise users and service providers can use the new REST API to perform the following system deployment actions automatically:

  • Download RP4VMs OVA image files.
  • Import OVA image files via vCenter wizard.
  • Configure vRPA networking (including IP address and connectivity to ESXi).
  • Open web interface and configure vRPA cluster in DM flow.
  • Pair between two clusters using credentials.
  • Receive operation status.
  • Register vCenter plug-in.
  • Install ESXi splitter without rebooting the ESXi.


  • Disk provisioning of copy VMs

When creating consistency groups users can now select the type of VMDK to use for the copy VMs. Possible options are thin, thick, or same as source. Default is same as source.

  • Expansion of VMDKs

VMDKs can now be expanded without loosing the journal or causing a full sweep for the entire consistency group in cases where users want to add additional space to protect the VMDK.

  • Exclusion of VMDKs

VMs containing VMDKs that are shared or non-persistent can now be replicated, as such VMDKs can now be excluded from replication.

  • Automatic replication of VMDKs

VMs can now also be configured to include newly added VMDKs from replication automatically.

  • Adding a VMDK without journal loss

Replication sets can now be added to a consistency group without causing journal loss or a full sweep.

  • Replicating VM hardware changes

Each production VM’s hardware resources (such as CPU, memory, etc.) can now automatically be replicated to its copy VM during image access.

Start-up sequence

Users can now define the power-up order of VMs in a consistency group (and consistency groups in a group set) as image access is enabled when testing a copy, failing over, or recovering production. VMs can also be marked as critical to stop the start-up sequence if that VM doesn’t power up.

  • User prompts

You can now define messages that must be acknowledged by RecoverPoint for VMs administrators before and after each VM’s power-up.

  • User scripts

You can now save and run scripts before and after powering on VMs by defining an external host per vRPA cluster in a RecoverPoint for VMs system.

  • Networking enhancements

All of the networking details of the VMs in a RecoverPoint for VMs system, or the VMs at a copy in a RecoverPoint for VMs system, can now be imported and automatically applied, or exported for future use.

Application-consistent bookmark support via VSS

Application-consistent bookmarks can now be created on every VMware-based virtual machine in its own consistency group that uses VSS and is running Windows 2008 or 2012 R2.

Scale and performance improvements

RecoverPoint for VMs 4.3 supports increased scale and performance, including the following scale improvements:

Parameter 4.2 4.3
Maximum number of vRPA clusters connected to a vCenter server 2 4
Maximum number of VMs that can be registered in the

inventories of all vCenters connected to a vRPA cluster

1024 5120

VMs system

1 2
Maximum number of replica copies per Consistency


1 2
Maximum capacity of a single VMDK 2TB 10TB
Total max capacity of a replicated VM 8TB 40TB

Getting started wizard

A wizard is now automatically displayed after the initial installation of a RecoverPoint for VMs system to guide users through the process of licensing and registering their RecoverPoint for VMs system and enabling support. This wizard is also displayed when adding the first license using the main RecoverPoint for VMs Management > Administration > Licenses screen.

Recovery activity reports

For each recovery activity a detailed report can now be displayed including the final status of each step, as well as the overall status, of the recovery activity.

EMC Storage Analytics (ESA) supports RecoverPoint for VMs

Hardware Enhancements

This version provides the following new features and changes:

  • 40TB, double-density X-Bricks: The system incorporates stronger hardware (CPU and RAM), providing the equivalent performance on larger X-Bricks.
  • New cluster configuration: Customers can deploy up to 8 X-Bricks in a cluster (20TB clusters in current version, 40TB cluster will support 8 X-Brick configuration in Q3)

Replication – Native RecoverPoint Integration

This version provides the following new features and changes:

  • RecoverPoint for XtremIO provides the best RPO in the All-Flash market (60 seconds using pre-defined RPO).
  • RecoverPoint can scale, according to the number of X-Bricks, by adding more RPAs.
  • The solution uses an innovative unique replication technique that leverages snapshot shipping and utilizes external CPUs for replication. It provides:
    • A better design to support the high performance I/O characteristic of all-flash arrays.
    • More resources are allocated for BW reduction and efficient transfer of snapshots (SCSI DIFF), resulting in more savings in BW costs. They include:
      • Compression
      • Deduplication
    • Further data saving is enabled on the snapshots stored at the target site. Any snapshot is deduplicated and compressed inline while data is written at the target snapshot.
    • Snapshot shipping enables immediate RTO at the target site and offers hundreds of point-in-time copies for recovery. It allows multiple tries for the administrators to select the best copy for a failover.

Non-Disruptive Online Cluster Expansion

This version provides the following new features and changes:

  • An XtremIO cluster can be expanded non-disruptively, while the cluster is online and serving data, adding agility to the data center. An XtremIO Storage Array can grow both in capacity and performance as more workload is consolidated into the system. This enables customers to start with a smaller cluster and expand it according to the workloads growth.
  • The added capacity and performance is available for consumption during the expansion process.
  • The following table shows the available expansion paths. (6 and 8 X-Brick clusters are supported only with the 20TB X- Brick type.)
