Featured Reviews

Senior Network Engineer at Holy Redeemer Health System, Inc.

High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"It is very easy to use, and it is very fast."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

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

"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."

"The main feature I have found to be product replication."

"The most valuable feature is Safe Mode."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

More Pure Storage FlashBlade pros

"Nutanix has the best customer support in town."

"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."

"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."

"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."

"DR and the replication power are valuable."

"The product's initial setup phase was simple."

"The feature that I find most useful in Nutanix Unified Storage (NUS) is the integration with Nutanix Move where you can seamlessly integrate it into your storage."

"It's a centralized place for management. With all our virtual machines and Kubernetes in there, it's a single place to manage all of our resources, instead of having to jump around to different places."

More Nutanix Unified Storage (NUS) pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"The features provided for SMB customers are limited."

"I would like to see the licensing fees improved as well as the price per terabytes."

"I would like to see more deduplication."

"There could be improvements in public cloud integration."

"It's on the expensive side, as expected for a niche product."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

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

"The solution is expensive."

More Pure Storage FlashBlade cons

"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp. It has snapshot, replication, high availability, and other data and storage-level replication, but there are some limitations."

"The pricing could be improved."

"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."

"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."

"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp it."

"Historically, it has been a hyper-converged infrastructure, so when you are looking to grow the solution, you need to scale the compute and storage. Having the ability to scale the storage independently would be a good improvement."

"Customer service is more difficult to call and they do not responding as much as, for example, DataCore. It's not the same level of satisfaction compared to DataCore. Responses could be faster."

"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."

More Nutanix Unified Storage (NUS) cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"The price could be cheaper."

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

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

"The price is a little high."

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

"We used a reseller for the purchase."

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

More Pure Storage FlashBlade pricing and cost advice

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

"The solution is highly-priced."

"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."

"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."

"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"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."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

More Nutanix Unified Storage (NUS) pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
