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.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

Managing mixed RAID workloads has improved data protection and delivers strong performance

VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."

"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."

"The availability and ease of use are the big features."

"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."

"Compared to other storage boxes, Everpure FlashArray is very useful because it is cost-effective and requires less work."

"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."

"Overall, I am sure that Everpure FlashArray is the best option on the market."

"Access speed and power consumption are most valuable."

More Everpure FlashArray pros

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

"The migration of servers feature makes server rack maintenance easy."

"Ease of use and the cost, compared to some of the alternatives, were pretty compelling."

"They are the best in class – I hold everyone else to their standard."

"The setup is really easy and straightforward, as vSAN is built in vSphere and you have a dashboard to manage the system."

"There was a significant reduction in the total cost of ownership."

"vSAN has just one datastore. so customers do not need to think where to put their VMs, how to design the physical disk RAID, the LUN size, the LUN mapping, etc. when they use NetApp/EMC/HDS or other storage systems."

"Having high availability without the need for a full vCentre/host license is a plus that, along with not needing a physical SAN, makes this solution great when you need functionality without the extra overhead of additional hardware and licences."

"The most valuable feature is the ability to continue our business needs and have higher visibility. It has definitely increased our business productivity levels."

Cons

"We have not had a good experience with the IBM device."

"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."

"They could improve the price."

"In Pure Storage FlashArray, the area with room for improvement is local MFA login."

"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."

"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."

"Improved reporting on the deduplication and compression functionality would be beneficial."

More Everpure FlashArray cons

"There is room for improvement in the area of horizontal scaling."

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"If they could introduce a write cache feature, the product would be perfect overall."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

"The vSphere Web Client is slow and clunky, making interacting with the system difficult and often times painful."

"We faced some latency issues but it's been a little better lately."

"The performance reports should be improved when customers are using third-party SSL certificates."

"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."

"When you don’t have a chance to build upon an existing vCenter service, you have to think about the deployment of vCenter without having vSAN. There are several options, like deploying vCenter temporarily on a client PC and then migrating it later onto the vSAN cluster, but it’s always a bit tricky and you probably need some extra time to get the installation done."

"The pricing is something of a concern."

"More modularity in terms of how nodes are provisioned (all nodes having to be the same size when deployed)."

"When designing the implementation for vSAN, I have noticed that it requires a minimum of six nodes, and this creates a problem when it comes to maintenance. If, out of the six nodes, I put one node in maintenance mode, then vSAN does not create other VM components."

More VMware vSAN cons

Pricing and Cost Advice

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"The solution is expensive."

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

"There is an annual or perpetual license required for this solution."

"It's a good price point and it's a solid product for the price."

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."

"The price is very reasonable when compared to other solutions."

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
