Featured Reviews

MikaelHellström

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.

System administrator at a library with 11-50 employees

A nicely-done product that provides a lot of graphs and reports to see what's happening in the background and makes configuration easier

It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st.

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"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 tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

More Pure Storage FlashBlade pros

"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."

"Nutanix technical support is excellent, with swift responses based on priority."

"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."

"The best features of Nutanix Unified Storage (NUS) are its simplified management, scale, and performance; data services can be easily consolidated, which help in disaster recovery services, replication, and reducing complexity and costs associated with this architecture."

"The life cycle managers of the PCMs are very impressive, and I like them. They make our lives easy when managing patches and security updates when they come in. A life cycle manager helps to consolidate different vendors."

"My overall rating for Nutanix Unified Storage (NUS) would be nine out of ten, as I have no complaints."

"I rate the overall solution ten out of ten."

"The scalability, ease of use, and technical support are the most valuable features of Nutanix Unified Storage."

More Nutanix Unified Storage (NUS) pros

"In terms of the hardware flexibility, with SwiftStack not being a hardware company, I literally buy any hardware that's the least expensive, from any vendor... from a flexibility standpoint, I think it's fantastic. I can go to anybody, anywhere - any vendor - and get my hardware."

"SwiftStack is also quite flexible when it comes to hardware. It depends, of course, on the use case and the kind of hardware you want to buy. But you have quite a bit of choice in hardware. The SwiftStack software itself does not impose anything on you."

"The scalability is phenomenal. It seems infinite, as long as you put enough storage in place, add enough nodes."

"The SwiftStack Controller, which is the web UI, provides out of band management. This has been one of the best features of it. It allows us to be able to do upgrades and look at performance metrics. It is a top feature and reason to choose the product."

"The biggest feature, the biggest reason we went with SwiftStack, rather than deploying our own model with OpenStack Swift, was their deployment model. That was really the primary point in our purchase decision, back when we initially deployed. It took my installation time from days to hours, for deployment in our environment, versus deploying OpenStack Swift ourselves, manually."

"It has helped us with the ability to distribute data to different data centers. As part of our DR strategy, we have nodes automatically replicating data from one data center to the other. This makes it easier for us to not have to shift tapes around."

"The performance is good. It is a secondary storage platform designed for archive and backup, so performance for the right use cases is very good. We have been pretty happy in that regard."

"The most valuable feature is its versatility. We use 1space and we can use it for almost anything: for our cloud service, for backups of VMs."

More SwiftStack [EOL] pros

Cons

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

"I have not seen ROI."

"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."

"Its configuration should be easier."

"I want efficiency. FlashBlade doesn't have efficiency now."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

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

More Pure Storage FlashBlade cons

"The only thing I would say is missing for us it is FTP protocol compatibility."

"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."

"The current hardware is not as dense as it could be. In our deployment, we have 2 PB per site, and we have to have 24 nodes. That's a lot of cabling and network ports that we use up. More dense nodes would be better."

"We couldn't access Nutanix Unified Storage (NUS) from Prism Central due to bugs. The bugs that Nutanix fixed in newer versions prevented us from accessing Nutanix Unified Storage (NUS) from Prism Central."

"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."

"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."

"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."

"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."

More Nutanix Unified Storage (NUS) cons

"The biggest room for improvement is the maturity of the proxyFS solution. That piece of code is relatively new, so most of our issues have been around the proxyFS."

"I would like to see better client integrations, support for a broader client library. SwiftStack could be a little bit more involved in the client side: Python, Java, C, etc."

"On the controller features, there needs to be a bit more clean up of the user interface. There are a lot of options available on the GUI which might be better organized or compartmentalized. There are times when you are going through the user interface and you have to look around for where the setting may be. A little bit more attention to the organization of the user interface would be helpful."

"The file access needs improvement. The NFS was rolled out as a single service. It needs to be fully integrated into the proxy in a highly available fashion, like the regular proxy access is. I know it's on the roadmap."

"They should provide a more concise hardware calculator when you're putting your capacity together."

"[One] thing that I've been looking for, for years as an end user and customer, for any object store, including SwiftStack, is some type of automated method for data archiving. Something where you would have a metadata tagging policy engine and a data mover all built into a single system that would automatically be able to take your data off your primary and put it into an object store in a non-proprietary way - which is key."

"At the moment we are using Erasure coding in an 8+4 setting. What would be nice is if, for some standard configurations like 15+4 and 8+4, there were more versatility so we could, for example, select 8+6, or the like."

"It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st."

Pricing and Cost Advice

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

"The product is very expensive."

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

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

"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."

"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."

"I feel that the price could always be lowered."

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

More Pure Storage FlashBlade pricing and cost advice

"The licensing model the tool has is cheaper than an HCI storage solution."

"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

"The solution’s pricing could be cheaper."

"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."

"The solution's pricing is fair."

"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."

"My company is in Brazil, and making the payments in dollars is tough for our organization."

More Nutanix Unified Storage (NUS) pricing and cost advice

"We are able to dynamically grow storage at a lower cost. We can repurpose hardware and buy commodity hardware. There is a huge cost savings, on average $100,000 a year compared to traditional storage for what we have at our size."

"One of their advantages of being a commercial open source platform is, for the scale that they offer, the pricing is pretty competitive."

"Dollar per gigabyte, it costs us more because we are storing more. However, if you look at it from a cost per gigabyte perspective, we have dropped our costs significantly."

"We find the pricing rather steep. Of course, you get quality for your money, that's absolutely true... [But] when you look at the prices of the licensing and the prices of your hardware, it's quite substantial."

"It's pricey for us because we're a nonprofit. I'm not privy to any amount or cost, but I have been told that it is pricey. There are no costs in addition to the licensing fees, and it seems to come with the support."

"The pricing and licensing are capacity-based, so it's hard to put my finger on them, because so many different vendors charge in different ways. We are still saving significantly over any of the other options that we evaluated because we can choose the best hardware at the best price, then put SwiftStack software on it. So, it's hard to complain, even though a part of me goes, "It would be nicer if it were less expensive.""

"All in, with hardware and everything else - and I hate to say a dollar amount because it's been awhile since I computed it - I know I'm under the $300 to $500 per terabyte mark. I call that my "all in" price, which has replications built in and protections built in."

"The annual support and maintenance costs compared to our old solution for backups had about a two-thirds savings, so about a 60% annual savings on our support and maintenance contract. That savings funded additional expansion for what it was costing us for the support and maintenance contracts on old solution."
