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.

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.

Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"It has benefited my organization because it has reduced time to insights."
"The most valuable feature of this solution is reliability."
"The initial setup was extremely simple and straightforward."
"The solution uses newer technology for deduplication and compression."
"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 high availability of the product is the most valuable feature."
"It has good, reliable, fast storage."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"We use it to implement all our VDI solutions."
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"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."
"We need better data deduplication."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"They could add more support for file storage and different types of storage."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."
"I would like to see more integration with other products."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"It needs more functionality and the ability to move across more landscapes."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
 

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"The product is expensive."
"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."
"With VMware, we pay $300,000 annually."
"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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The solution is very expensive."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"Our costs are roughly $200,000 a year."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"I liked the price point when we purchased it."
"The solution is very expensive."
