What is our primary use case?
It serves as a centralized network location accessible to all staff members within our district school district, including technology personnel, teachers, and administrators. We utilize it as a shared file repository, allowing individuals to access necessary files from any computer based on their assigned policies.
When we decided to implement Nutanix, we aimed to address several challenges. Firstly, we were dealing with an outdated NAS server that had been in place long before my tenure at the school district. It was over ten years old and required a hard drive replacement within the first year of my arrival due to failure. Secondly, we sought to minimize our data center's footprint by consolidating our infrastructure. Rather than adding more equipment to accommodate our needs, Nutanix allowed us to streamline services by consolidating them onto our existing virtualization platform.
How has it helped my organization?
It has effectively managed our unstructured data, including audio and video files. We've experienced smooth operations without any complaints regarding uploading or downloading videos. While video usage isn't as frequent, we primarily utilize it for downloading videos related to specific incidents for administrators or our police department. We've encountered no issues uploading files of any kind.
Transitioning from VMware to Nutanix has highlighted the overall flexibility of Nutanix's platform. Unlike VMware's three-tier system, Nutanix simplifies the learning curve by streamlining operations. The update process, in particular, has been favorable, with no critical issues encountered.
The resiliency of Nutanix hasn't been thoroughly tested in our environment so far. However, I routinely check fault tolerance settings to ensure they meet our requirements. During the update process, I've observed critical errors occur as hosts restart, but Nutanix's self-healing mechanism handles these issues seamlessly.
The benefit of using Nutanix is evident in several ways. Firstly, we've effectively compressed our storage while significantly expanding our overall storage pool. Previously, our service had a capacity of twenty-five terabytes, but with Nutanix, we've scaled up to a hundred and twenty terabytes physically and approximately fifty terabytes logically. This expansion has been accompanied by noticeable improvements in performance, particularly with reduced latency and IOPS well within the boundaries of our equipment.
All our resources are centralized in a single location for managing and running storage: our data center. We operate three Nutanix nodes within this center, effectively managing everything from one central location. We don't have any other locations outside of our data center running a Nutanix cluster.
Nutanix's capability to eliminate silos within our organization's storage infrastructure was discussed during our recent call with the engineer. Although we haven't explored this feature extensively yet, there's a forthcoming project where we anticipate leveraging it.One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.
What is most valuable?
Currently, the most valuable aspect of our Nutanix implementation is its file storage functionality.
What needs improvement?
One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.
For how long have I used the solution?
We transitioned from a VMware environment to Nutanix over a year ago, during which we also introduced Unified File Storage capabilities alongside our existing Enterprise Storage solution.
What do I think about the stability of the solution?
The occurrence of lagging and downtime has been very minimal since we migrated most of our servers. It has been an improvement overall. Any lag that may occur would likely be imperceptible to the average user. Occasionally, I may receive minor warnings in reports, such as a recent anomaly where computation usage nearly reached a hundred percent during midday. However, this did not impact everyday use, and it was only noted upon reviewing the report later in the day.
What do I think about the scalability of the solution?
I can't provide a definitive assessment of scalability as we initially started with a three-node cluster. However, in terms of deploying virtual machines, Nutanix has demonstrated greater efficiency with resources compared to our previous VMware setup. Previously, I often had to allocate significant amounts of RAM and CPU resources to servers. With Nutanix, resource allocation requirements are notably reduced. For instance, where I would typically allocate a four-core CPU and eight gigs of RAM, I can now achieve similar performance with just two cores for the CPU and two gigs of RAM. This efficiency in resource utilization suggests that we have ample runway to deploy more virtual machines as needed.
Which solution did I use previously and why did I switch?
Before migrating to Nutanix, our infrastructure was based on VMware. Regarding other services, we utilize Unified Storage and operate within the hyper-converged Acropolis hypervisor environment for our virtual machines. This setup allows us to leverage the multi-cloud infrastructure aspect in conjunction with Unified Storage. The integration between Unified Storage and our Acropolis hypervisor environment has been excellent. The reporting functionality is highly readable, and I appreciate how it includes links to knowledge-based articles whenever critical errors occur.
When comparing the security features of Nutanix to VMware, we didn't delve deeply into security with VMware. However, with Nutanix Files, I appreciate the ransomware feature. This feature allows us to add known malicious file names to a list, preventing any uploads of those files into the system. I find this feature valuable, especially considering past incidents like the Log4J malicious code. If any other threats arise in the future, we can easily add them to the list for protection.
What about the implementation team?
Initially, when we purchased the solution, I wasn't involved in the hardware selection process. Instead, a third-party technology firm handled the initial deployment since I lacked full certification or expertise in Nutanix at the time. However, since then, I've obtained the Nutanix Certified Associate certification.
Two individuals were involved in the deployment process, with one acting as an overseer while the other handled the entire implementation. Following the deployment, the latter provided me with an Excel sheet containing all the usernames, and passwords for Nutanix admin users, and an overview of the tasks completed.
The only maintenance task I handle is performing life cycle management updates, which I conduct twice a month. This includes software and firmware maintenance. As for physical maintenance, there haven't been any requirements since the nodes were purchased.
What other advice do I have?
For new users considering Nutanix, my advice would be to first assess your specific goals and needs within your environment. Determine what you're aiming to achieve—is it more efficient virtual machines, a smaller footprint in your data center, or reduced energy consumption. In our case, transitioning from VMware to Nutanix significantly reduced our footprint from a full six-foot rack to just three small servers. This not only reduced space requirements but also improved energy efficiency. Additionally, if you're dealing with outdated hardware, Nutanix could be a viable option to explore. Considering recent changes, such as VMware's shift towards more subscription-based models and potentially less customer-oriented programs, evaluating Nutanix's offerings in alignment with your organization's mission and views may be worthwhile. Overall, I would rate it nine out of ten.
