MikaelHellström - PeerSpot reviewer
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.

Achieve cost-effectiveness with superior performance while needing to address cluster support
I am working with Microsoft Storage Spaces Direct for applications, SQL, and VRS. I am an integrator for this solution The price performance is the best advantage of Microsoft Storage Spaces Direct. They introduced the All-Flash array using SSD or NVMe drives without cache drives. It is…

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.

Quotes from Members

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

Pros

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"The initial setup is pretty easy and simple."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"It's very easy-to-use."
"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."
"We have seen a reduction in the total cost of ownership by around 20%."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"Its technical support is excellent."
"The performance, reliability, and affordability has been most valuable."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The initial setup is straightforward."
"The main positive impact that Microsoft Storage Spaces Direct has had on my company over the years is increasing performance; our checks show it is three times faster than VMware, making us extremely happy and motivated to keep using it."
"The flash ability, in terms of tiering and caching, is amazing"
"DR and the replication power are valuable."
"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."
"It removes a layer of aggregation to present storage to end users, so we do not have Windows file servers. This benefits our company by reducing one of our attack planes from a cybersecurity perspective, so we do not have to worry about the OS."
"On a scale of one to ten, I rate this solution a seven."
"The features I appreciate the most about Nutanix Unified Storage (NUS) are the compatibility with the market."
"Nutanix has the best customer support in town."
"We transitioned from a three-tier architecture to Nutanix Unified Storage (NUS). With the Files offering out of Nutanix Unified Storage (NUS), we were able to migrate those shares with a smaller footprint."
"I would rate Nutanix Unified Storage a ten out of ten."
 

Cons

"Pure Storage FlashBlade should improve on more cloud integration."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"It would be nice if you could store file-based in the same box with the same technology."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."
"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."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"I would like to see better integration."
"Microsoft closed the shared cluster support, which is important for the solution."
"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."
"It is difficult to get a hardware compatibility certification for the solution."
"I think the online documentation needs a lot of work and so do the sizing tools."
"Microsoft closed the shared cluster support, which is important for the solution."
"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."
"More optimization could be done in terms of mirroring."
"Documentation management could be improved"
"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."
"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."
"Perhaps when it comes to deploying NUS virtual machines on top of CVMs, it should not be necessary for it to be in all of them or they should require fewer resources on the servers."
"The product needs to work a bit more on its ransomware detection capabilities."
"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."
"The GUI is not user-friendly for new users and has room for improvement."
"I would like to see the integration of artificial intelligence and machine learning technologies. That could definitely be a major breakthrough in providing a unified, seamless experience for end-users. It could reduce costs as well as human effort."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
 

Pricing and Cost Advice

"I rate the tool's pricing a seven to eight out of ten."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"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."
"The pricing for FlashBlade is between cheap and moderate."
"I feel that the price could always be lowered."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"The solution is expensive."
"Cost-wise the product is one of the more affordable within the category of products."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"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."
"The product has an annual licensing fee."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."
"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."
