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.
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.

Quotes from Members

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

Pros

"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"The complete block and file sharing are the most usable features."
"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."
"It is a stable solution that sells a lot...The deployment phase of the product was very easy."
"It is easy to set up the solution."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"The most valuable thing for our use case is the flexibility to have multiple-protocol support."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Technical support has been helpful and responsive."
"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."
"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."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The latency is good."
"It has good, reliable, fast storage."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
 

Cons

"In some countries, spare part availability is an issue for us."
"Scalability for the 650F is good, but I was expecting a little bit more."
"The pricing is a bit higher than expected."
"It could be a little easier to attach it to a network file system."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"There are some challenges with data encryption and reduction."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In the future, I would like to see integration with enterprise backup systems."
"It is on the expensive side."
"There is room for improvement in the pricing of the product."
"We need better data deduplication."
"In terms of what needs improvement, the dashboard and management could be simplified."
 

Pricing and Cost Advice

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"Licensing is easy since all the software is included."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"We have to apply for a license for each system."
"The solution is very expensive."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"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."
"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."
"Our licensing fees are $500,000+ USD."
"The support cost per array is about $20,000 a year for 24/7 support."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"We pay approximately $50,000 USD per year in licensing fees."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"Given its price, Pure is not the first option."
