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.

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."

"Manageability is its most valuable feature; it is simplified storage, as we don't have to maintain or administer it on a daily basis, which is good, and we can depend on the solution's ability to phone home and leverage the built-in support function of the product."

"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."

"It is fast and reliable. It works."

"The management is simple in Pure Storage FlashArray."

"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."

"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."

"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."

More Everpure FlashArray pros

"It is great because it can work as a SAN and net storage."

"We're using Dell EMC Unity as our primary storage for our production and for our DR site, we've had no performance issues with it whatsoever and we're using it for everything."

"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."

"It is easy to scale, maintain, and manage."

"The solution helps us be more competitive in the market against our competitors."

"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."

"It is easy to manage; a lot of the system manages itself, and it is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."

"Using this solution has meant that I do not need to look for different partners to provide me with solutions like a backup service. Dell provides end to end solutions."

More Dell Unity XT pros

"We have high use cases for SQL databases, most of our business critical applications use SQL to allow us to complete the DoD mission needs, so we have been using the EF-series for about two years now and everything has been going smoother and faster."

"The speed is the most valuable feature."

"The product's initial setup phase can be managed easily and completed in 20 to 30 minutes. It is one of the fastest storage tools that you can implement."

"The solution is very good; it offers very good performance and very good data services to customers."

"For anyone who has critical workloads like Oracle databases or DB2, NetApp All-Flash Arrays will suit their needs, as long as it fits within their budget."

"The replication and mirroring features are very good."

"The deployment is very quick and very simple to use."

"Our use case is both corporate storage and for all of our datacenter and back-end enterprise applications."

More NetApp EF-Series All Flash Arrays pros

Cons

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

"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."

"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."

"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current."

"I would like to see them develop the ability to integrate with more AWS services."

"I think replication is one area that still needs improvement."

"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."

"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."

More Everpure FlashArray cons

"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."

"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."

"We need to improve the controller to work as active-active. We also need to improve the snapshot on the Unity site."

"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."

"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

"I haven't seen the roadmap for this solution."

"The dedupe and compression ratios on the Unity are not quite where we want them."

More Dell Unity XT cons

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

"It says NetApp on the badge, but it’s not a NetApp product."

"The solution should really build out a more hyper-converged product."

"I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays."

"Better integration with other brands is important so we would like to see it easier to integrate."

"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."

"We need a center related to NetApp in Egypt so that we can deal with them directly."

"From a manageability perspective, I like the look and the feel of the FAS series better than the EF. I think it's more straightforward and simplistic."

More NetApp EF-Series All Flash Arrays cons

Pricing and Cost Advice

"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."

"There are no fees for licensing. The hardware is paid for only once."

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

"We have seen a reduction in total cost of ownership."

"The price of the solution is not expensive."

"The pricing of Pure Storage FlashArray is reasonable."

More Everpure FlashArray pricing and cost advice
