About – Drew Tonnesen

As my blog is eponymous, I’ll simply say for the past 13 years (over 20 in tech) I’ve worked for Dell Technologies (Dell EMC), most of that time in PowerMax Engineering focusing on virtualization technology and how to integrate it with both our hardware and software platforms. My primary focus is on the VMAX/PowerMax platform and VMware but I also work with many other Dell EMC products like VPLEX and RecoverPoint and other virtualization technologies. In addition to testing these integrations I write whitepapers and TechBooks, frequently work with customers, and even create some other content like the Dell EMC VMAX and PowerMax Content Pack for VMware Log Insight.

  1. Hi Drew,

    I hope you do not mind me contacting you for a quick answer to an interesting question?

    I have inherited a previous vSphere 5.5 platform (circa 2014 build) leveraging the following:

    vSphere 5.5
    SRM 5.8
    VMAX 10K
    Physical EMC Recoverpoints for Production and Recovery Sites
    Existing Consistency Group with 3 LUNs ( replicating successfully )
    NO VSI’s installed for political reasons ( seperate storage and SRM admin teams )

    The UK company is standing up a new vSphere 6.5 platform but leveraging the same storage above and the same physical EMC Recoverpoint?

    My question is, can this be done ?

    1. Two SRM Instances ( SRM 5.8 ans SRM 6.5 ) with their SRAs configured to use the same RPA’s.?
    2. The RPA configured with separate Consistency groups with separate set of LUNs ?
    3. The separate Recovery Plans would never be run in tandem.

    Their idea is that they have DR for both platforms during a phased period before the workloads and infrastructure is migrated from the vSphere 5.5 platform to the vSphere 6.5 platform.

    Best Regards


    1. Hi Robert,

      I don’t see an issue with this since they are two distinct environments. I have something similar in my lab as I have to run multiple vSphere versions but each one accesses the same RecoverPoint environment.


  2. Hi, we have Active-Active scenario which is provided by VPLEX. some VMs are held on VDL LUNs and should be protected as active LUN in the second site.So far, we’ve been using this feature integrated by HA, but I’m going to change it and use SRM. Also,a number of our other VMs are protected by Recoverpoint as the Active-passive solution. Now, I want to use SRM by combining with two SRA (RP and VPLEX) simultanously. Do you think we can add two SRA at the same time in just one SRM Server? is it work properly?
    what do you think we should change in our design and infrastructure? if you are possible, give me some technical details about it.

    1. I guess this is the same questions asked twice? You don’t have to change anything to use two SRAs. SRM will recognize them both, and then you configure the VMs as required for each different technology. For example, I have the SRDF SRA and RP SRA in the same environment.
