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.

Storage platform has improved data performance and has provided reliable support for my clients
It's difficult to know how DataCore SANsymphony can be improved. I think DataCore SANsymphony could be deployed on Linux environments, which could be a great thing for clients. I would like to see the stabilization of the Veeam implementation in the future, and perhaps the integration or officialization of compatibility with Proxmox and XCP-ng. With Proxmox, it wasn't easy while integrating it with third-party solutions. It's working, but it was a bit difficult to deploy.

Offers good features like Fusion and stable product with better customer service
Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

Quotes from Members

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

Pros

"It simplifies storage."
"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."
"Everpure FlashArray has helped my customers reduce downtime; I cannot tell you how much downtime, but definitely one hundred percent."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"It releases those to new teams within minutes at a very small storage cost amount."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."
"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."
"Technical support is amazing; it is very fast and always has a solution in no time."
"Our central storage has very high availability. DataCore SANsymphony ensures high business continuity."
"We are now able to run a hot standby solution for our virtual systems with separated server rooms (in case of fire), and so we can minimize downtimes of our IT infrastructure."
"Inexpensive for the amount of storage."
"The most valuable feature for us is that we can adjust the size of the storage very easily, without stopping production."
"DataCore SanSymphony helps us to have a real performant and secure storage system."
"It is a very stable solution."
"It has a feature called Fusion that makes it more secure and productive."
"At the time, it was a great way to get a proper SAN solution for a good price."
 

Cons

"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"The negative aspect of Everpure FlashArray is that migrations can be somewhat complicated."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"The cost of the storage needs improvement."
"They should work on their upgrades, they're not smooth."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"The initial setup of the product is complex."
"I think replication is one area that still needs improvement."
"Customer support is hit or miss. There are good technicians, however, some are not so good."
"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."
"I think an easier way to open a service call, right through the DataCore GUI, would be an improvement, especially when there is an urgent issue."
"The graphical interface needs to be improved. We have noticed some bugs in it."
"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparison."
"The so-called hyperconverged infrastructure edition, sometimes known as vSan, should be addressed."
"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."
"The solution is constantly evolving."
"Lots of tweaks had to be done in order to get everything working right, and support is now outsourced and horrible."
"There were some SMB issues, but they were resolved."
 

Pricing and Cost Advice

"I don't know the exact cost but it's around $1,000."
"The price is reasonable."
"There is an annual or perpetual license required for this solution."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"It is cheaper than NetApp."
"Cost-wise, it's been very effective."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"Make sure you are made aware of the annual subscription cost when purchasing."
"The pricing and licensing are better with DataCore."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"The solution is cost effective."
"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."
