Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

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

"Everything, especially the VMs inside, is pretty fast."
"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."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The database workloads are pretty fast because I frequently move data from here to there."
"Overall stability is very good. It is a very stable solution."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."
"Stable flash storage platform with good scalability, efficiency, and speed."
"Inline data reduction is pretty impressive."
"I think Dell Unity XT is one of the best options on the market at the moment, although there is some good competition."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"We need better data deduplication."
"I would like to see replication and DR features in the next release of this solution."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"There are some challenges with data encryption and reduction."
"The UI for this solution needs to be improved."
"They could add more support for file storage and different types of storage."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"It could be a little easier to attach it to a network file system."
"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."
"Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"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

"Given its price, Pure is not the first option."
"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 support cost per array is about $20,000 a year for 24/7 support."
"As far as the licensing costs, everything is included in the license."
"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."
"The licensing is on a yearly basis."
"Our licensing fees are $500,000+ USD."
"With VMware, we pay $300,000 annually."
"Pricing for this product is manageable, though slightly higher than comparable products."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"The solution should be cheaper."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"We have to apply for a license for each system."
"The ROI is right where we need it to be. It's a reasonably priced array."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"Obtaining a warranty is easy."
