Featured Reviews

Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Nabeel Sayegh - PeerSpot reviewer
Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.

Quotes from Members

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

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The solution is scalable."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"It has good, reliable, fast storage."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The solution is very straightforward to set up."
"Technical support has been helpful and responsive."
"Performance is a top feature."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"It is easy to scale, maintain, and manage."
"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"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 simple to use and easy to manage. We don't touch it after we set it up."
"The most valuable feature is the ability to provision storage from the CLI, versus having to go in and use the GUI every time. I can just script it out and it will create what I need. That makes it super-easy to manage. Also, for us, it's a set-and-forget. Once we provisioned it out, we haven't had to mess with it."
"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"The deduplication and compression rates are beyond impressive."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"It worked flawlessly."
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"The most important feature of any storage array is its reliability, measured by its uptime."
 

Cons

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I would like to see replication and DR features in the next release of this solution."
"In the future, I would like to see integration with enterprise backup systems."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"The tool's pricing is higher than competitors."
"The VNX reporting is much more granular, versus the Unity reporting."
"We would like to see more advanced integration capability added to this solution."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"I would like to see more integration with other products."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"The price of the solution can improve."
"Most of our upgrades have not been as smooth as they should have been."
"The file functionality could be better."
"It was not proactive communication."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."
"The speed can always be improved."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"I would love for them to have a hyper-converged solution."
 

Pricing and Cost Advice

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"The support cost per array is about $20,000 a year for 24/7 support."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"As far as the licensing costs, everything is included in the license."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"We pay approximately $50,000 USD per year in licensing fees."
"The licensing is on a yearly basis."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."
"The price is good for commercial grade storage arrays."
"Licensing is easy since all the software is included."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Pricing is as high as it has ever been for EMC."
"The solution’s pricing is competitive."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"The price is too high."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We have seen a reduction in total cost of ownership."
"It is cheaper than NetApp."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
