    • Journal Sizing Tool help

      I needed some help with estimating journal sizes. I found the tool here: https://www.zerto.com/myzerto/technical-documentation/?search=Journal%20Sizing%20Tools A few questions on this: 1. How current is this, and what version of Zerto does this tool apply to? 2. Is there any supplemental help documentation in relation to this tool? 3. I noticed the zip contains several different version […]

    • Network Address Translation

      For situations where some applications may have hardcoded / absolute IP addresses is it possible to create a scenario with NAT?  The notion would be that a NAT device residing in the target site would front end the replicated machines.  Should an outage occur, then only DNS would need to be changed, but not the […]

    • How does Ip change occur on start up?

      Zerto has the capability to change IP address of a server within a VPG when it boots up (either in a test or live scenario).  I am wondering how it does this exactly.  What script is it using, what attribute is it changing in the OS, etc? Further to that, is there an interoperability matrix […]

    • Dual-NIC ZVM for Traffic Separation – Feedback?

      Hi all, I just posted this to my blog after a grueling week on my migration project.  I figured I should share it in case anyone runs into the same troubles in working with isolated networks and firewall exceptions as a last resort.  Could someone take a look and provide any feedback?  Any concerns with […]

    • Protect SQL System Disk Only

      Our SQL team has their own process for data recovery and they would like us to only protect their System Drives.  The storage team does not wish to house all of the SQL data at the recovery site, if it is not going to be used for recovery as it just takes up space.  I […]

      Hello I’m running Zerto with vCloud Director and have customers replicating in from their onsite vSphere clusters in a DRaaS setup. We have our Zerto Journal data on a dedicated datastore.  I need to move this to a new storage array so needs to be moved to a new datastore.  I can make the new […]

    • ESXi upgrade (in-place new install)

      I am looking to upgrade about 100 ESXi 5.1 hosts to ESXi 6.  Half of these hosts have VRA running. This will not be in-place upgrade.  I will be reinstalling ESXi6 over existing ESXi5.1 hosts. What would be the best practice?

    • Best Practices for Oracle on Windows 2012

      Hi all.  I’ve read the Best Practices for Oracle whitepaper by Zerto.  It seems there are 2 means by which to ensure a consistent database is available on the recovery side:  1) Use Powershell scripting to place the Oracle database into Hot Backup Mode and run such a script as often as possible and 2) […]

    • SQL Always On

      We are just tossing ideas around with our new data center layouts.  One idea that was suggested is splitting our SQL always on cluster between two data centers instead of using Zerto for replication.  While we understand there is some advanced configurations that would need to be done to prevent an accidental failover – or […]

    • Zerto Maximums?

      I’ve searched the forums and documentation repos for maximums/limits for Zerto.  I’m working on a comparison with Site Recovery Manager, and this is one of the criteria for comparison I need to provide to management in my report.  Is anyone aware of any maximums document produce by Zerto?   Thanks!

    • VM to VPG Grouping

      Are there any recommendations on grouping VMs to VPGs ? i.e. Basing VPG membership on start order, application, or fill-in-the-blank? I have also heard we should keep VPGs to 15 or fewer VMs. Can anyone confirm?

    • Storage performance and best practices

      Hi All, I have been pondering for some time now on what would be best for Zerto and its storage requirements, especially in a multi-tenant DRaaS environment (such as we have). Would welcome members comments on their own experiences regarding this topic as I think it would be useful for many of us. One thing […]
