Featured Reviews

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.

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.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

More Pure Storage FlashBlade pros

"The best features of Nutanix Unified Storage (NUS) are its simplified management, scale, and performance; data services can be easily consolidated, which help in disaster recovery services, replication, and reducing complexity and costs associated with this architecture."

"What I found to be the most valuable features were better performance and uptime."

"It is a highly scalable solution."

"Nutanix Unified Storage is very stable."

"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."

"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."

"It's a centralized place for management. With all our virtual machines and Kubernetes in there, it's a single place to manage all of our resources, instead of having to jump around to different places."

"Nutanix Objects is reliable."

More Nutanix Unified Storage (NUS) pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"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."

"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."

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

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"I have not seen ROI."

"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

"The pricing can be quite high."

"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."

"Historically, it has been a hyper-converged infrastructure, so when you are looking to grow the solution, you need to scale the compute and storage. Having the ability to scale the storage independently would be a good improvement."

"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 solution should keep adding new features to be competitive in the market."

"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."

"There is an occasional language barrier between some of the technicians, which can be challenging; however, that doesn't prevent us from being assisted, as they can remote in and use Pulse to view our cluster and gather logs and reports."

"The solution is very expensive."

More Nutanix Unified Storage (NUS) cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

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

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

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

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

"Our licensing is renewed annually."

"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."

"We used a reseller for the purchase."

"The price could be cheaper."
