Precisely Assure MIMIX vs. HPE Zerto Software

MIMIX is clearly the best IBMi solution for most high availability and disaster recovery situations. It provides rock-solid replication and agile ability to switch quickly. In its earlier days, some organizations used it as a primary daily system backup method. With the advent of Ransomware, this is no longer advisable. The strength of MIMIX real-time replication becomes a weakness if IBMi data becomes infected. As in any real-time replication product, at that point, two systems are infected.

Zerto is well suited for disaster recovery and virtual machine replication between multiple data centers. DR testing for audit or regulations is much easier with Zerto, great reporting, dashboard etc. It is not well suited for physical server replication for disaster recovery or as a primary backup solution.

• Redundancy - needs to be available at a moment's notice.
• Protection - the business would be greatly impacted, therefore protection of production systems is key to the business succeeding.
• Usability - needs to be user-friendly, easy to navigate and operate, as it will be required at any given time.

• Anyone with a large disk (VMDK) knows the issues of VMware snapshots. Most backup software is a "point in time backup" that uses snapshots. While the backup can be run multiple times per day the stress of the snapshot on the host and storage is eliminated by the continuous protection of Zerto log replication.
• A client had a the disks on a VM go missing for some reason. We had them "flip the switch" for a real fail over and press the fail over button. The VM on our DR site started to come alive as the VM at the customer site was brought down. When the DR VM was fully up, automatic reverse replication started. The DR machine was available in a few minutes (to take into account different host hardware) for access. One the vm at both sites were in sync, we had the customer again repeat the fail over process and the DR site VM was turned off and the Production site VM was brought back on line. This was a 200 GB VM and the whole process was finished in about 3 hours.
• Zerto also allows for "Test" fail overs that can be configured on many different functions, such as host, datastore, network and IP usage. Configuring the IPs is crucial to avoid inadvertent site cross contamination of the same VM.
• Zerto can also retrieve files from any VM disk on the DR site without starting a VM. Very handy for retrieving files or directories.
• Since Zerto is running continuous log replication, changes on the production VM are nearly instantaneously copied to the DR site. As with any data process, having sufficient bandwidth for "churn" peaks minimizes the delay in updating the DR site.

• Possible false sense of security for ransomware attacks.

• Moving a VM from one protection group to another could be simplified.
• I would like to see an executive-style report of recovery and testing for upper management.
• The ability to deploy Zerto as a virtual appliance, without the need for a windows server.

We really like the easy setup of this replication solution, as well as the ease of management. Not to mention, our internal IT Economist determined that the Zerto solution would provide the best ROI out of the competing solutions we analyzed. So far, his calculations have been spot on, and we have saved substantially

Zerto is very easy to implement and support. Uses are broad, only issues are once something doesn't sync it is difficult to get assistance until your reach tier 2 or tier 3 support. Basic file and folder recovery is great. Live and test fail overs are also easy to implement without issue.

MIMIX is software built for availability. By its nature it is must be available. As long as the underlying system and communication network are available MIMIX is working. And if there are failures in either of those, MIMIX is designed to allow for a quick and resilient recovery once underly systems or communications are restored

I have never seen MIMIX itself be a performance bottleneck. However it is important to consider the network in overall performance of any remotely replicated systems. MIMIX can only replicate as fast as the network allows. But a strong capability of MIMIX is its ability to "buffer" its replication, so it can be sent without error as the network allows

Support is available and efficient. Response time is good and likelyhood of a quick resolutiion is high. However the mature solid product and proactive management tools, fortunately make support requirements relatively rare. The support for version upgrades is also strong, but again the basic upgrade process is usually straightforward and well documented.

Incentivized

Overall support is very good. We sometimes get pushback when asking Level 1 support to escalate to Level 2. This causes undue frustrations when you need a more knowledgeable support person to get involved. We've had to escalate to account reps a few times for this scenario. Zerto is very responsive and normally handles our requests very quickly.

Make sure the end goal is in mind before implementing. That way results meet expectations.

We used MIMIX for its role for iSeries high availability. We used Double Take by Vision Solutions for our production Windows environment. MIMIX is designed for iSeries, and Double Take was designed for Windows. We had VMware virtual environment, running multiple VMs for production ERP Lawson M3, now Infor. Both MIMIX and Double Take played the role well for what needed to be done. Without either MIMIX or DoubleTake, the business would have been impacted.

We started out using Backup Exec which was in service until we virtualized our environment where it didn't perform as well at the time. Then we switched to Veeam which worked well, but then as we started needing to do migrations and off-site DR, we found ourselves relying on Zerto more often.

For my organization, the pricing model was an upfront investment for the Zerto licenses. My organization prefers to pay upfront and not deal with month-to-month or year-to-year pricing models that most companies are moving to. But for some, the investment may be more than they can afford, and would prefer the year-to-year pricing model.

MIMIX works to its intended functionality. It provides real time data replication across multiple partitions and systems as defined. I have never witnessed any problems with MIMIX in scaling to larger systems or adding new data groups. In conjunction with the inherent scalability of IBMi scalability and configuration flexibillity are rather quick and easy.

I mean, it was 6 years ago, but we were up and going with all applications synchronizing in short order. The longest tasks was getting the 30 TB of application data synchronized between the datacenters.

• MIMIX had a positive impact, as the organization has had to rely upon the unplanned switch.
• MIMIX definite must if organization is running i Series, and business needs are 24/7.
• Without MIMIX in place, the downtime impact to the business would have been great.

• Zerto is like having the best possible insurance ... it just works, and often provides the backups taken overnight that are key in recovering data/work between overnight backups.
• Zerto easily enabled the move of primary datacenters by allowing easy failover to a secondary site, and failback to the primary site.
