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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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.

Quotes from Members

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

Pros

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It has good, reliable, and fast storage."
"The cost for Pure may be high, but the reliability and scalability make it well worth the money."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"I appreciate the performance."
"It has drastically improved the performance of our high-end Oracle databases and allows us the ability to replication to a DR location with ease."
"The solution is very straightforward to set up."
"High performance and ease-of-management are the most valuable features."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"With so much technological advancement and more coming, the world is their oyster."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"Compared to VNX, the Unity is a lot easier to use."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"Stable flash storage platform with good scalability, efficiency, and speed."
"Unity XT is very good compared to Fujitsu and IBM."
"The architecture is robust; it was the good, old-fashioned storage array, block array for customers, and it's reliable."
"User friendly interface"
 

Cons

"They could add more support for file storage and different types of storage."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"One area that I haven't been sold on yet is the POD replication."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"The monitoring matrix and its dashboard need work."
"The monitoring matrix and its dashboard need work."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"In future releases, I look forward to more AI features."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"The ease of installation, sometimes, for the customers, is not that positive because the customers think they can do it themselves."
"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 payment account area."
"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."
"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."
"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."
"I'm not sure if it has a single pane of glass management console. That would be something we would like to see."
"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."
 

Pricing and Cost Advice

"The licensing is on a yearly basis."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"As far as the licensing costs, everything is included in the license."
"The product is expensive."
"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."
"With VMware, we pay $300,000 annually."
"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."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"I think we pay around 100 grand per year for three arrays or four arrays."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"It scales, but then you have to buy additional stuff."
"It is a good return on investment."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"The solution should be cheaper."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
