High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

Pros

"It is very easy to use, and it is very fast."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The initial setup is pretty quick."

"Using this solution has made our backups more reliable."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

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

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

"I would rate Pure Storage FlashBlade a ten out of ten."

More Pure Storage FlashBlade pros

"The most valuable feature is the easy interface."

"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."

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

"We migrated over to Nutanix and saw an immediate improvement in the performance."

"I like Nutanix Prism Central. The primary benefit is that we can manage everything from the same page."

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

"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."

"What I appreciate most about Nutanix Unified Storage (NUS) is its user-friendly nature."

More Nutanix Unified Storage (NUS) pros

"The technical support team is excellent."

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

"It's very easy to upgrade storage."

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

Cons

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

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"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."

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

"The feature that we're waiting on is better integration with the cell services."

"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

"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."

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

"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."

"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."

"One thing I'd appreciate is having a desktop application similar to what VMware offered."

"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."

"Some of the new features in the tool cannot be used with just one click, as was possible in the past."

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

More Nutanix Unified Storage (NUS) cons

"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."

"The user interface could be simplified."

Pricing and Cost Advice

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

"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 for FlashBlade is between cheap and moderate."

"The price could be cheaper."

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

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"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."

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

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

"The pricing is fair."

"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."
