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.

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.

Cons

"It would be nice if you could store file-based in the same box with the same technology."

"Pure Storage FlashBlade should improve on more cloud integration."

"I would also like to see better support for CIFS workloads."

"Its configuration should be easier."

"The documentational aspect of FlashBlade needs improvement."

"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."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

More Pure Storage FlashBlade cons

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"More optimization could be done in terms of mirroring."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"Microsoft closed the shared cluster support, which is important for the solution."

"I think the online documentation needs a lot of work and so do the sizing tools."

"Documentation management could be improved"

"Microsoft closed the shared cluster support, which is important for the solution."

More Microsoft Storage Spaces Direct cons

"The current hardware is not as dense as it could be. In our deployment, we have 2 PB per site, and we have to have 24 nodes. That's a lot of cabling and network ports that we use up. More dense nodes would be better."

"The dashboard could be more customizable"

"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."

"Nutanix Unified Storage (NUS) can be improved in the area of big data workloads, as we still need to improve performance there."

"If they can add an integrated DLP feature, it would be great."

"Unified Storage failed to fulfill our object storage requirements."

"The pricing can be quite high."

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

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

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

"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."

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

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

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

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

"Our customers have seen a reduction in TCO."

"The product is very expensive."

More Pure Storage FlashBlade pricing and cost advice

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"The solution is expensive."

"Cost-wise the product is one of the more affordable within the category of products."

"Nutanix is very competitive."

"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."

"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."

"The solution is highly-priced."

"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."

"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."

"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."

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