Solutions Architect at Recovery Point Systems

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.

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.

Quotes from Members

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

Pros

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The most valuable features are the Metro clustering, and disaster recovery."

"The initial setup is pretty easy and simple."

"The product is scalable and easy to expand."

"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."

"We can capacity plan at a greater level than we used to."

"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 solution provides many controllers."

More Pure Storage FlashBlade pros

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

"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."

"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."

"The migration from VMware to Nutanix Unified Storage (NUS) is less complex and less troublesome, and the replication and clustering are very good."

"The product is good, easy to upgrade, easy to use, and user-friendly."

"Nutanix Unified Storage (NUS) is very scalable."

"I strongly recommend Nutanix Unified Storage (NUS) to all users."

"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."

More Nutanix Unified Storage (NUS) pros

"It's very easy to upgrade storage."

"Notable features of Gluster FS include flexibility, scalability, stability, and ease of use."

"The technical support team is excellent."

"The price tag is good compared to the amount of data and high availability provided."

Cons

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

"The documentational aspect of FlashBlade needs improvement."

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

"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."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"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."

More Pure Storage FlashBlade cons

"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."

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

"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."

"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."

"The GUI is not user-friendly for new users and has room for improvement."

"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."

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

"The licensing terms are restrictive, as they go by terabyte cost."

More Nutanix Unified Storage (NUS) cons

"The user interface could be simplified."

"The system should be more intuitive and easier to manage."

"There is a feature in Red Hat’s commercial version that could be beneficial if integrated into the open-source version."

"The performance of the solution must be improved."

Pricing and Cost Advice

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

"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."

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

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

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

"The product is very expensive."

"The price could be cheaper."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

More Pure Storage FlashBlade pricing and cost advice

"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. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."

"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."

"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."

"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."

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

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

"The product is pricey."

"The pricing is a bit too high."

More Nutanix Unified Storage (NUS) pricing and cost advice

"If you need cheap storage, but still need high availability, it's a good product to look at."
