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.

Good performance and reliable but the setup is complex

We would like to see a self-sufficient installation. Nowadays it's open-source, but the installation is still tied to the vendor, which means it is unlikely that it is going to scale. I want them to tap into the broader community. It is really emerging, they have a year over year, 50% annual growth. With a 10-year-old company, it will certainly bring a lot of interest, and will certainly make it more successful, if they tap into that growing customer base. They have to make themselves relevant to the industry. The industry is totally geared to the Cloud, DevOps, and geared for agility. The software with the appliance in my set is already outdated, and it is not that it cannot sell, but it has to be tapping into the emerging and growing sectors to continue with the customers and businesses. This is what the requirement is, to improve their technology. Which means that they have to make themselves relevant to the industry.

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"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."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

More Pure Storage FlashBlade pros

"Unified Storage's centralized management features enable us to accomplish whatever we want in terms of operations and migrations."

"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."

"I would rate Nutanix Unified Storage (NUS) a ten out of ten."

"On a scale of one to ten, I rate this solution a seven."

"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."

"Whenever we have some necessity in terms of capacity and expansion of infrastructure, it's like a Lego system where they can just place in some more nodes and our needs are met."

"The most valuable feature of Nutanix Unified Storage is redundancy."

"The solution's most valuable feature is the Prism Central centralized management console."

More Nutanix Unified Storage (NUS) pros

"The technology is stable which is good."

"Workflow is easy to manage and maintain."

Cons

"The documentational aspect of FlashBlade needs improvement."

"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."

"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."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

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

"Its configuration should be easier."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

More Pure Storage FlashBlade cons

"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."

"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."

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

"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."

"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."

"The only thing I would say is missing for us it is FTP protocol compatibility."

"There are some techniques that need to be improved because sometimes, during processes, it gets stuck on the console, requiring command line interventions, indicating gaps between the GUI and command lines."

"Nutanix Unified Storage (NUS) sits in a good place for us. The biggest improvement would be to make it more cost-effective from a storage node and storage perspective, so that the solution isn't such a question when it comes to cost-prohibitiveness versus potentially other vendors."

More Nutanix Unified Storage (NUS) cons

"Lacks some ability to integrate with different systems."

"We would like to see a self-sufficient installation."

Pricing and Cost Advice

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

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

"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."

"Our licensing is renewed annually."

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

"Nutanix Unified Storage isn't expensive."

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

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."

"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."
