Eric Black

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.

Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

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.

Quotes from Members

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

Pros

"The most valuable feature is Safe Mode."

"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."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"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."

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

"The product is scalable and easy to expand."

"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."

More Pure Storage FlashBlade pros

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"The shared storage capability is highly valuable."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."

"I rate the stability of Amazon FSx ten out of ten."

"On a scale of one to ten, I would rate Amazon FSx a ten."

"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."

"The customer service executives of all Nutanix products are active and responsive."

More Nutanix Unified Storage (NUS) pros

Cons

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

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

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

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

"I have not seen ROI."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"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."

"They need better integration with public clouds along with a better hybrid solution."

More Pure Storage FlashBlade cons

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"A direct FTP feature would be beneficial instead of relying on transmission services."

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."

"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."

"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."

"Regarding areas where Nutanix Unified Storage (NUS) could improve, they should focus on pricing transparency and reducing licensing complexity."

"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."

"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."

"In summary for improvements, I would say stay on the integration path, keep those integrations heavy, and let us use the software and technologies with everybody."

"The pricing could be improved."

"The product needs to work a bit more on its ransomware detection capabilities."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

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

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

"Licensing fees are paid yearly."

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

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

"Our licensing is renewed annually."

"The price could be cheaper."

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

More Pure Storage FlashBlade pricing and cost advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."

"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

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

"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."

"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."

"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."
