Featured Reviews

MikaelHellström - PeerSpot reviewer
IT Manager at Regin Dalarna
Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Unified storage has simplified private cloud operations and delivers strong security and ROI
Regarding areas for improvement, I think Data Lens could be enhanced from Nutanix's side, but it has been a long time since I logged into that console, so I do not remember much. It is a SaaS-based offering on the Nutanix portal. It is not something you deploy on-premises; it is not on-prem access. You connect your cluster to the SaaS-based Nutanix and then access the Lens console. I need to check it since it has been almost two or three months since I logged in. Nutanix Enterprise AI actually needs to improve a lot if I compare it with any other product such as NVIDIA and other offerings in the market. Nutanix Enterprise AI still requires a lot of work. I did not check that in much detail technically, but whatever I thoroughly checked, it still lags behind in many features. When it comes to AI-related features, I think the ecosystem of Nutanix is not as big as NVIDIA because NVIDIA has its own inferencing system and model training platform such as NeMo, NeMoTron, and others. Nutanix does not have such things. It can be built using NVIDIA CUDA libraries, but what I saw when I was testing the product is that you can run NVIDIA NeMo and PyTorch and two other things, but as a software, Nutanix does not have an end-to-end platform. That is something Nutanix should focus on.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"This solution has improved how our organization functions in the way that it has essentially made us not have to think about storage."
"The most valuable feature of this solution is performance."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"For those who are interested in using this solution, I would recommend it."
"We haven't had any issues with it, it's easy to use, and the speed is incredible."
"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."
"The number one aspect of FlashBlade is performance; the ability to move large amounts of data through a training array is pretty much unparalleled, and the scalability has been great."
"I would rate Pure Storage FlashBlade a ten out of ten."
"DR and the replication power are valuable."
"The solution is stable and extremely easy to calibrate."
"The product is good, easy to upgrade, easy to use, and user-friendly."
"The customer service executives of all Nutanix products are active and responsive."
"The performance of Nutanix Unified Storage (NUS) increased almost 50%."
"The product's initial setup phase was simple."
"Management-wise, it has made work a lot easier. It is all in one place physically. It is much better now."
"The most valuable feature is the easy interface."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Quest QoreStor is very stable compared to our previous solution."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
 

Cons

"Its configuration should be easier."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"I have not seen ROI."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"It's on the expensive side, as expected for a niche product."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"Nutanix Unified Storage (NUS) can be improved in the area of big data workloads, as we still need to improve performance there."
"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."
"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."
"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."
"Nutanix Unified Storage (NUS) can be improved involve the limitations I've seen in Files Analytics, specifically to the number of FSVMs today that File Analytics can analyze."
"The graphical user interfaces could benefit from more attention to detail."
"The ransomware protection of QoreStor could use improvement."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
 

Pricing and Cost Advice

"I understand that it is competitively priced compared to other brands."
"The pricing for FlashBlade is between cheap and moderate."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"Licensing fees are paid yearly."
"The price of this solution could be made more affordable."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"The product is very expensive."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"The solution's pricing is better compared to other products."
"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."
"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."
"The pricing is fair."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
