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.

High availability and user-friendliness enhance infrastructure health and redundancy
I would rate technical support from DataCore SANsymphony a 10. Each time I contact the technical support, it's when I don't have a choice because it's very difficult for me on site, and each time, I have good people online who are able to help me solve the problem. Usually, the problems are not very technically difficult, but sometimes they are, and the support team is still there to help us resolve them. The majority of the problems are linked to licensing, so when the license has expired or the number is not correct, they are proactive and change things live, which is very good.

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.

Quotes from Members

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

Pros

"The scalability is good."
"The amount of throughput that we're getting is really nice."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"It is always out of the box, and ready to use."
"Very efficient storage"
"The solution is very reliable."
"Everpure FlashArray has helped my customers reduce downtime; I cannot tell you how much downtime, but definitely one hundred percent."
"Pure is simple to set up and manage on a day-to-day basis."
"The bottom line is the software is what runs our applications on whatever storage vendor we choose - and it does so reliably."
"The use of the RAM cache allows you to speed up the writing and reading of data while also allowing for a possible increase in performance by increasing the RAM on the servers."
"DataCore’s comprehensive storage services stack has long been known for harnessing ultra-fast processors and RAM caches in x86 servers, for superior performance and enterprise-class availability."
"If you have multiple block storage, as in a silo, then you can use SANsymphony to manage the storage from one management portal."
"It is a very stable solution."
"This product has a good ratio between quality and price; in many cases, it's less expensive to work with DataCore than other storage systems."
"SANsymphony-V offers a comprehensive set of storage virtualization functions to build a very robust storage network that speeds up applications, ensures business continuity and facilitates disaster recovery."
"Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great."
"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."
"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."
 

Cons

"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"It can go down from time to time, but it's been pretty solid so far."
"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"Reports of performance and LUN utilization could be improved."
"Its interface could be better."
"The client console should be improved. It starts slowly and heavily."
"For customers or technicians that don't speak and understand English, it could be great to have other languages support, all the more so given the number of countries in which SanSymphony is used."
"I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays."
"I found it a little unnecessary to have to rename the configurations within the graphics console in order to have unique names."
"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."
"The only area I see lacking with DataCore is their support; it's not very good at all, and it's frankly very frustrating and has almost caused me to swear off the product."
"The graphical interface is not always very stable."
"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."
"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."
"There is room for improvement in the area of horizontal scaling."
 

Pricing and Cost Advice

"It could always be lower, but it's okay."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"Pure Storage FlashArray's pricing is very competitive."
"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."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"The solution is cost effective."
"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"The pricing and licensing are better with DataCore."
"Pricing has improved but it is still expensive."
"Make sure you are made aware of the annual subscription cost when purchasing."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
