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

"It saved a lot of space, as far as physical space in our data center."

"It's extremely stable and has good performance."

"One could tell, the minute we switched to this program, everything ran a lot faster."

"We chose Pure Storage primarily because of its combination of performance and ease of use."

"Pricing is very competitive, and it's better than other competitors, as we've looked at some of the other competitors on the market."

"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."

"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."

"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."

More Everpure FlashArray pros

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

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

"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."

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

"Stability-wise, I rate the solution a ten out of ten."

"The primary use of the solution is the virtualization and storage process in a simple platform."

"When we went to vSAN, at that point in time, we doubled the density of our desktops per host and, for the first time ever, I could demonstrate a significantly lower TCO for a VDI desktop versus a rich or fat client."

"Previously, we were using three-tier architecture; however, after adopting a CA solution, we are only on a single console and we have cut down the EU engineers we needed as we did not require multiple engineers for managing multiple layers, and now we have a single engineer who can manage everything from the top layer from a single console."

"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."

"For a PaaS platform which I’ve developed, the scalability of VMware vSAN was a necessary feature enabling us to grow with the onboard customers."

"It uncoupled the idea of proprietary technology and component capabilities, and it is basically a proprietary technology for a cost-effective infrastructure."

"We chose this solution as the domain for hyper-convergence solutions for small businesses with fewer than 200 employees for companies that wanted to increase storage without complications."

More VMware vSAN pros

Cons

"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."

"The price of this solution is high and should be lowered."

"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."

"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."

"Pricing could be better in comparison to other solutions."

"The main disadvantage of Pure Storage FlashArray is the price."

"Pure Storage FlashArray could improve by being more secure."

"I would like a feature to integrate with external or cloud solutions."

More Everpure FlashArray cons

"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."

"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."

"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."

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

"It would be ideal if the solution offered some intelligent monitoring."

"Hardware load balancing is available on the enterprise version of the solution, however, it's extremely expensive and therefore out of our budget."

"I would like to see it be more hardware-agnostic. Other than that, the only other complication is - and it has gotten better with the newer versions - that lately, once you're running an all-flash, if you need to grow or scale down your infrastructure, it's a long process. You need to evacuate all data and make sure you have enough space on the host, then add more hosts or take out hosts. That process is a little bit complex. You cannot scale as needed or shrink as needed."

"I would love for this product to be cheaper and easier to configure."

"Anytime I have encountered issues with stability, it usually was the result of a poor design or poor implementation."

"We want see a better monitoring tool in vSAN. Monitoring is not that great as of now because it shows us false alarms in the Health status. We would like that to be improved."

"The pricing is something of a concern."

"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."

Pricing and Cost Advice

"The price of the solution can be a bit expensive. There is an additional fee for support."

"The price is reasonable."

"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."

"FlashArray is expensive, but the quality justifies the price."

"We are finding the TCO of flash to be lower than SSD implementations."

"It's expensive, but you get what you pay for."

"It is cheaper than NetApp."

"For us, as the customer, it reduced the price of the management."

More Everpure FlashArray pricing and cost advice

Information not available

"The price is okay."

"We pay a yearly licensing fee."

"It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive."

"It is slightly expensive. They can be more competitive in terms of pricing."

"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."

"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."

"The product's price has been increasing lately...VMware vSAN is expensive."

"Clients have to pay for VMware vSAN licensing based on the number of CPUs. The purchases would be lifetime or perpetual, but you need to have support, e.g. the support is negotiated from one, two, three, or four years."
