Eric Black - PeerSpot reviewer
The ability to leverage multi-tenancy along with immutability is a huge benefit for us
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. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Pricing challenges overshadow efficient data handling and fast deployment
In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.

Overall functions well, stable, but technical support could improve
Veritas Access Appliance installation is user-friendly. You need network team cooperation for the setup of the cluster configuration. The Veritas Access Appliance initial configuration process is broken into two phases. The first phase requires that you perform each configuration step on each individual node. You should have two terminal windows open during the first phase, each logged into one of the nodes. During the second phase of the initial configuration, you should only perform the steps on one of the nodes. When you start the second phase of the initial configuration, close one of the terminal windows and continue doing the steps on only one of the nodes. When you initiate the cluster configuration, the settings that you configured on the current node are copied over to the second node in a one-time synchronization event.

Quotes from Members

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

Pros

"It performs well and it is also very fast."
"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."
"The initial setup is pretty easy and simple."
"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."
"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%."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"The solution provides many controllers."
"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."
"The interface is quite simple. It is very good. It is easy to configure. It also has a powerful CLI."
"I strongly recommend Nutanix Unified Storage (NUS) to all users."
"In the beginning, when they sold us Nutanix Unified Storage (NUS), they told us the performance would be 30%. Then we came to them and said, 'You are a liar. It's not 30%, it's 800% increase.'"
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"Nutanix Unified Storage (NUS) is very fast in terms of migration and data access with respect to VM, OS, and storage, experiencing a 30% faster performance compared to VMware."
"Nutanix Objects is reliable."
"Nutanix Unified Storage (NUS) is very scalable."
"Overall the solution works well."
"It is a very stable program."
 

Cons

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"I would like to see the licensing fees improved as well as the price per terabytes."
"Its configuration should be easier."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"There could be improvements in public cloud integration."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"The solution is expensive."
"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."
"Nutanix should improve the one-click upgrade. There are a lot of dependencies on third-party licenses and HP hardware we use internally. The one-click upgrade fails sometimes."
"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."
"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."
"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees."
"Pain points are just in the management and understanding of how the functions work."
"The pricing can be quite high."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"The interface is not logical. It should be a little simpler."
"I would like to see more platforms added."
"The Veritas support for Access Appliance could improve. They are a pioneer in the industry, and they provide an enterprise-level solution. However, when comparing the storage, they can't compete with the NetBackup solution."
 

Pricing and Cost Advice

"I rate the tool's pricing a seven to eight out of ten."
"Our licensing is renewed annually."
"The price is a little high."
"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."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"Licensing fees are paid yearly."
"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."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"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."
"It is very good. It is much more competitive than a dedicated storage platform."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"The solution's pricing is better compared to other products."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"The solution is highly-priced."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"The solution’s pricing could be cheaper."
"The solution is not expensive compared to other storage solutions."
