Room For Improvement

The Everpure FlashArray needs UI customization, deduplication, NAS support, pricing adjustments, cloud integration, encryption, and enhanced user experience.
Dell PowerStore requires enhanced cybersecurity, NAS functionality, affordability, user support, interface, connectivity, AI integration, and simpler management.
Dell XtremIO faces challenges with volume limits, user interface, replication, upgrades, support response times, and scalability.
Integrating object storage into the FlashArray would benefit entry-level and SMB customers by offering a more unified solution.

Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Resilience has supported proactive management and secured audit readiness across multiple sites
The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

Has improved data reduction and snapshot efficiency while supporting critical workloads
There are some areas that could be improved with Dell XtremIO. The API to connect with command line or to see performance very clearly could be enhanced, similar to how NetApp works with Grafana and NetApp monitor, which shows you a comprehensive view of the whole picture. The snapshot functionality could work more similarly to Snap Center. If I want to see all the VCenter with the VM, I think it needs the API for this. I do see big differences between Dell and other products. NetApp works very closely with VCenter, and Hitachi also integrates well, but Dell is not very clear and does not proceed well with VCenter integration with Dell. It needs the API, and I need to see all the snapshots. If I want to restore a VM from only a few directories or a few files that I need to restore, it is very difficult. I do see some differences in licensing. For the last few years, the Dell EMC price is acceptable. A few years ago, Dell EMC was expensive, approximately 20 percent more than NetApp. Right now the budget between EMC and NetApp is very closely aligned. Regarding the installation process and deployment of Dell XtremIO, I notice that in Israel, a lot of professional services and engineers who work with Dell EMC have moved to another storage company. I do not know why. Dell EMC does not have enough engineers, system engineers, or professional services engineers to provide service to the old clients, similar to how NetApp or Hitachi do. I think Dell XtremIO is between easy and complicated to deploy; it gives you the whole picture, but I need to go closely to VCenter to connect to VCenter to see the snapshot and to see performance with more dashboards of performance. I also need to connect the switch fiber channel to see all zoning to give me more flexibility to install or configure fiber channel or to see the performance of the fiber channels. I think there should be some fiber channel disconnect adapter or better troubleshooting from hardware for errors.
