Eric Black - PeerSpot reviewer
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.

A robust solution with good performance and support
This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

Offers satisfying data protection and workload movement features with exceptional stability
Nutanix Cloud Infrastructure can be used up to 100% of its capacity, but our company is presently using 80% of the solution's resources. Our company manufactures iron casting products in the metal industry, and Nutanix Cloud Infrastructure is also used. For virtualization purposes, Nutanix Acropolis is used as a full-stack solution. For the Windows virtual machines in our company's server, Nutanix Acropolis is utilized instead of solutions like VMware Hypervisor. One of the main reasons our company adopted Nutanix Cloud Infrastructure was its data protection features. The solution is also used in disaster recovery through the automatic snapshots feature on the local site. Next year, our organization will try to join clusters in the network using the solution. Network clustering will help our organization's team move workloads into the geographical cluster automatically. Nutanix Cloud Infrastructure is considered an ideal solution for disaster recovery where data protection remains embedded. The solution is capable of even capturing auto snapshots for remote sites. Next year, our company plans to test new features of Nutanix Cloud Infrastructure that will assist in automated workload movements on two sides at a distance of 60 kilometers. I would recommend others use the solution for its exceptional stability, performance, hardware compatibility, and overall flexibility. Nutanix Cloud Infrastructure allows the use of varying hardware for the same cluster. I would rate the solution a nine out of ten overall.

Quotes from Members

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

Pros

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"The most valuable features are the Metro clustering, and disaster recovery."
"Speed and ease of use are the two most valuable features."
"The onboarding and integrated monitoring tools are pretty good."
"The solution provides many controllers."
"It performs well and it is also very fast."
"The ease of use is the solution's most valuable aspect. It's very user-friendly."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"The speed of the operations and of creation of VM is fantastic."
"We are suggesting Nutanix to the management because of scalability and time efficiency."
"It consolidates our servers, and improves our electricity consumption and cooling as well."
"One of the most valuable features is the One-Click Upgrade. When I need to update the system, I do it with one click. This product is amazing because everything is easy to manage, from network management to snapshots."
"The most valuable aspect of Nutanix is the performance of the storage, which is excellent. And controlling compute, storage, the network, and security all together in one box is very efficient for us. It gives us a single platform to manage our all infrastructure."
"The technology of Nutanix Acropolis AOS is the most valuable feature. You don't need multiple screens to manage."
"Karbon is a must-have as it drastically simplifies the deployment of Kubernetes."
"Nutanix Cloud Infrastructure's most valuable features are all the cloud facilities or benefits it provides for my data center."
 

Cons

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"Its configuration should be easier."
"I would like to see more deduplication."
"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."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"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."
"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."
"The reporting mechanisms need improvement."
"he interface is not user-friendly so the ease of use could be improved."
"In the future, I would like to see integration with external storage using the fiber channel"
"The licenses for Nutanix are very complicated."
"Nutanix Cloud Infrastructure's cloud platform management software could be improved so that I can manage my load between the cloud and on-premises."
"Notifications could be improved as they're not currently very useful."
"I would like to see official compatibility with Red Hat in the future."
"Our client had some old Citrix Xen servers for which there is no direct migration. Nutanix has a move utility for Microsoft Hyper-V clusters or VMware clusters. You can easily migrate them using the move utility, but the Xen clusters cannot be migrated in a simple way. That is the only thing that is lacking, but nowadays, no one uses the Citrix Xen server for their clusters. Everything else is already there. Nutanix keeps on upgrading its hardware's or hypervisor's capability to be able to support new technologies."
"We had a few problems with the foundation machine that you can use to build your systems out. We've got it working now, but it should be improved."
"Areas for improvement would be the memory setting and the CPU setting reserve features, which are not available on Acropolis. I also feel that the DR solution, the reporting, and the component that is combined with the Nutanix OSP need to be improved."
 

Pricing and Cost Advice

"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."
"I feel that the price could always be lowered."
"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."
"Licensing fees are paid yearly."
"I understand that it is competitively priced compared to other brands."
"The price could be cheaper."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."
"If you are cost-sensitive then this solution is not for you."
"Nutanix Cloud Infrastructure's pricing is higher now."
"The pricing is very competitive when compared with other vendors. As long as Nutanix goes forward with the same price and same type of offering, it will definitely have a large number of customers adopting the same solution very soon."
"The solution could be a little less expensive."
"The price of the solution is high."
"Our customers are on three years license to use Nutanix Acropolis AOS. The price of the solution includes all features and support."
"The pricing of Nutanix is not cheap but there are options available."
"Nutanix Acropolis AOS is affordable, it has good value. The final price depends a lot on the hardware used, it's an appliance in the end. Whether you use HPE as the hardware vendor or Supermicro as the hardware vendor, it really depends on what hardware is used which is the main cost."
"Our licensing fee on the total setup up was about R900 000."

Nutanix vs. VMware EVO:RAIL vs. FlexPod
Originally posted at www.storagegaga.com/dont-get-too-drunk-on-hyper-converged/ I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned…
