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.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"If it's financially viable for you and you can afford it, it's worth it."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"The deduplication and compression meet all of our system requirements."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit we saw, from our very first benchmarks, was that our production databases simply ran twice as fast with no other changes."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."
"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."
"The most valuable aspects of Dell PowerStore are the promising roadmap, and the interesting features to come."
"What I appreciate most about Dell PowerStore is its performance and speed."
"The graphical interface does everything and we don't need to use the CLI; we can do everything, and it's user-friendly and simple."
"Gives us flexibility, performance, and ease of use. It also has some very good compression capabilities. We were looking for a solution that was easy to install in our VMware environment, that was flexible. PowerStore X is a type of a VMware cluster that you install inside your environment. If you have a VMware environment, like we have in production, it's easy to install and use."
"I like the performance of the PowerStore. When you talk about PowerStore, it's mainly about flash systems and high-end IOPS. The 1000T is a midsize box, in terms of the way the vendor positions it, but it is more than enough for our needs."
"The use of NVMe is notable, and the speed and performance it provides are commendable."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"It took us a year to get it to stabilize and to get the best out of Pure."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"Some of the data metrics we get out of Pure from a support perspective online are a little bit more robust than the Dell PowerStore metrics, but it's not a negative against Dell."
"Dell PowerStore's IOPS needs to be better; this is the only downside I faced."
"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating the product."
"Dell PowerStore is a very expensive storage solution. That said, the speed for recovering information is amazing. I would make the product cheaper. The discounts from Dell to South America are not sufficient because we need better pricing. The discounts for small PowerStores are not enough to close deals since I'm a distributor. As both a user and seller, it's challenging to sell Dell PowerStore to the channel or final customers because we don't have enough discount from Dell."
"There are some issues in the firmware and operational system for Dell PowerStore, such as certificate issues from legacy firmwares."
"The support team doesn't always provide adequate assistance. So, there is room for improvement in the support."
"I have experienced some issues, downtime, and outages with Dell PowerStore, as we have had quite a few issues related to storage and resilience."
"The support is not very good."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"Pure came in at a better price point than EMC and performed better than Compellent."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"The best features come included without any additional cost."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The cost has room for improvement."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."
"PowerStore's pricing is reasonable."
"It is easy to work with Dell from the licensing perspective."
"The solution’s pricing is always too high."
"The solution is expensive."
"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."
"The price of Dell PowerStore could improve. The price should be managed more compared to Huawei Dorado or IBM All-Flash series."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
