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.
Vipin Kumar Sha - PeerSpot reviewer
Pricing challenges overshadow efficient data handling and fast deployment
In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.

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

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"It has good, reliable, fast storage."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"I appreciate the performance."
"The most valuable feature of this solution is its ease of use."
"The solution is scalable."
"The most important point is the simplicity of the API integration. We can leverage the API integrations and connect our hybrid-cloud network environment with Nutanix's cloud storage."
"What I appreciate most about Nutanix Unified Storage (NUS) is the efficiency in terms of storage capacity and reuse."
"I appreciate its storage licensing model, as it offers flexibility."
"Nutanix Unified Storage is easy for end users to access. They can use it like any other drive on their systems. We have mapped it in the user system so they can scan files and store them. They can use it just like an Android drive."
"The solution's most valuable features are its support and speed."
"We have seen reduced overheads and increased efficiency with Nutanix Unified Storage (NUS)."
"The solution is very easy to manage."
"Based on my experience, I rate Nutanix Unified Storage (NUS) ten out of ten."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"It helps to simplify storage because it has an easy front-end to access everything."
"It is fast and reliable. It works."
"The most valuable feature is its speed."
"It is always out of the box, and ready to use."
"The deduplication and compression rates are beyond impressive."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Maybe the price can be reduced since the solution is very expensive."
"Adding some functions to the product would be beneficial."
"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."
"The software layer has to improve."
"The tool's pricing is higher than competitors."
"I would like to see replication and DR features in the next release of this solution."
"The interface could be improved."
"There should be more automation. Going deeper, I would appreciate seeing out-of-the-box automation for storage provisioning and maybe some more customer-facing, web portal-type or API functionality to Jira or ServiceNow."
"I have heard that there have been latency problems."
"It is challenging to configure access control settings."
"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."
"Unified Storage failed to fulfill our object storage requirements."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"I would like to see data tiering to AWS."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"We haven't seen ROI."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The price could be better."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"Given its price, Pure is not the first option."
"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."
"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."
"The licensing is on a yearly basis."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"Nutanix Unified Storage isn't expensive."
"I'm happy with the cost and licensing because I don't have big volumes."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"We purchased a license to use this solution and we pay for the storage ourselves."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"The pricing is reasonable."
"The price of Pure Storage FlashArray is expensive."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"FlashArray is expensive, but the quality justifies the price."
