Featured Reviews

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.

Amarnath Charugundla

System Engineer at Tata Consultancy

Unified management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

Consultant at PBOservicos-Informatica

A solution backed by strong customer support, that is stable and scalable

As a company managed in a Kubernetes environment, being trusted by a Kubernetes vendor, Red Hat creates barriers against using other certified solutions that work. Because IBM is a competitor of Pure Storage, things seem to be getting worse. I don't have plans to use Portworx Enterprise in the future because, at the moment, I am working with Ondat, and I have to follow NetApp's direction on that. When evaluating Portworx, one should make sure their company has already chosen Pure Storage. Still, if they are evaluating the solution on Ondat or Dell or other platforms, they should get a roadmap statement from Pure Storage, that they will continue to develop storage hardware diagnostics. I rate Portworx a nine out of ten.

Quotes from Members

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

Pros

"We have seen a reduction in the total cost of ownership by around 20%."

"The most valuable feature is Safe Mode."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"It's very easy-to-use."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The solution provides many controllers."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"The product is scalable and easy to expand."

More Pure Storage FlashBlade pros

"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."

"I would rate Nutanix Unified Storage (NUS) a ten out of ten."

"What I appreciate most about Nutanix Unified Storage (NUS) is its user-friendly nature."

"The solution is easy to use, share, and manage."

"I like its interface. It is very interactive and simple to use."

"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."

"Customer support for Nutanix Unified Storage (NUS) is top-notch."

"What I appreciate most about Nutanix Unified Storage (NUS) is the efficiency in terms of storage capacity and reuse."

More Nutanix Unified Storage (NUS) pros

"The best thing about Portworx is the Stork, they have called the VPS (Volume Replacement Strategy) and they also have topology awareness, and these are the three features I like."

"A custom IBM script is designed to tackle the storage management challenges within containerized environments, providing crucial data services and features required for enterprise applications."

"I like that you have a small dedicated file system that is fast and resilient for containerized workloads."

"Portworx virtualizes the aspects of the underlying block storage. That is good because they can also use block storage for their future deployment instead of just NFS."

"Portworx is a simple solution. It's similar to Pure Storage products. They're all easy to use and install. You need to have a little expertise with containers to use Portworx, but it will be no problem for you if you understand containers."

"The solution is user-friendly."

Cons

"I would like to see better integration."

"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 could be improvements in public cloud integration."

"I would like to see more monitoring capability included in the next release of this solution."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"I would also like to see better support for CIFS workloads."

"I have not seen ROI."

"The speed could be improved."

More Pure Storage FlashBlade cons

"It's still pretty expensive."

"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."

"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."

"The solution should increase its storage capabilities."

"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."

"I believe that one of the most complicated parts of Nutanix Unified Storage is the configuration of the DNS issue in Active Directory. Sometimes it is a bit complicated to troubleshoot or detect an error when integrating it with Active Directory."

"The graphical user interfaces could benefit from more attention to detail."

"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."

More Nutanix Unified Storage (NUS) cons

"The integration has room for improvement."

"They have not integrated Portworx with Ondat since they are too focused now on Pure Storage APIs and not on users like us."

"I would like to see a more native mapping to mainframe-type systems."

"It would be highly advantageous to include an integrated backup solution within the same license, rather than purchasing backup separately."

"The documentation could be better."

"I think the vendor could provide more training for new users who may not be familiar with containers."

Pricing and Cost Advice

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"I rate the tool's pricing a seven to eight out of ten."

"The product is very expensive."

"The price of this solution could be made more affordable."

"I understand that it is competitively priced compared to other brands."

"The pricing for FlashBlade is between cheap and moderate."

"Licensing fees are paid yearly."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."

"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."

"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."

"The pricing is a bit too high."

"The price of the license is expensive when comparing it to traditional storage."

"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."

"It is not too high for what we are using."

"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."

More Nutanix Unified Storage (NUS) pricing and cost advice

"The price of Portworx Enterprise is high."

"The price is competitive, but it is too expensive when paired with Red Hat IBM."

"It has two offerings. One is free, which is limited to only five nodes. The other is enterprise, which is a bit pricier."

"I'm not sure how the licensing was broken out, but I don't think our offering of the Portworx was more than USD $20,000."
