Pure Storage FlashBlade

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.

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.

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."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"Speed and ease of use are the two most valuable features."

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

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

"It performs well and it is also very fast."

More Pure Storage FlashBlade pros

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

"The solution's most valuable features are its support and speed."

"It is unified. This is the best thing that Nutanix gave to the world. You can do everything from one point."

"The feature I like most about Nutanix Unified Storage (NUS) is the ability to optimize storage spaces."

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

"I appreciate its storage licensing model, as it offers flexibility."

"The performance of Nutanix Unified Storage (NUS) increased almost 50%."

"We had three racks full of storage and now it is just half a rack."

More Nutanix Unified Storage (NUS) pros

"The general consensus on what we've done is that the restores coming back from it have been faster than they were from our prior vendor. Ingest speeds are fine. The restore speeds have improved."

"The graphs are most valuable. They have a lot of graphs and reports that you can run to see what's happening in the background to configure OpenStack Swift."

"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."

"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."

"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 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

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"Its configuration should be easier."

"I would like to see better integration."

"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."

"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."

"I have not seen ROI."

"I would like to see more VM-Aware features in the next release of this solution."

More Pure Storage FlashBlade cons

"Pain points are just in the management and understanding of how the functions work."

"The solution needs to be more open to integration with other vendors. Sometimes, we struggle with the support process. Our skilled engineers must explain our problems to everyone, even though we've already done preliminary investigations. The support team follows standard procedures, which can be painful. We're not a small customer, especially in the life sciences sector, so we'd appreciate more specialized support. I've heard Nutanix Unified Storage has teams dedicated to life sciences and healthcare; we should be part of that."

"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."

"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 solution's monitoring and security features could be improved."

"I have heard that there have been latency problems."

"Requires higher upfront investment"

"The documentation on the support site needs to be improved."

More Nutanix Unified Storage (NUS) cons

"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."

"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."

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

"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."

"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."

"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."

"[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."

"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."

Pricing and Cost Advice

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

"Our licensing is renewed annually."

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

"We used a reseller for the purchase."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

"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."

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

"The pricing is a bit too high."

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

"The solution is highly-priced."

"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."

"The solution's pricing is fair."

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

More Nutanix Unified Storage (NUS) pricing and cost advice

"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."

"COST_SAVING; We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"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."

"The pricing model is great and makes sense. We have talked about how to get into more of a frequent billing cycle than once a year. That would be an interesting concept to add into the product, having the ability to have monthly billing instead of having to do a one-year licensing renewal. However, the way the license works by charging for storage consumed is definitely what makes them the most competitive."

"We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"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."

"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."
