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.

Offers a unified platform, reduces downtime, and simple updates

MahendraPanchotiya

Infrastructure Manager at ER Tech Pros

Nutanix offers a unified platform for managing databases, virtual machines, and applications. This simplifies management by consolidating everything into a single interface. While Nutanix may have a higher upfront cost compared to other hypervisors, it can significantly reduce the resources needed for infrastructure management. With our previous hypervisor, we needed nearly ten IT personnel. Nutanix has allowed us to streamline our team to just three members. We use a combination of database technologies, including SQL databases and web servers such as IIS, BHP, and NGINX. Nutanix features helped our organization reduce downtime. I don't recall the last time we had downtime related to Nutanix because it is such a stable product. Nutanix, a reliable product, helps us streamline our processes, which in turn improves company revenue. We began to see the benefits after two years, with a 40 percent reduction in operational costs. We migrated 200 servers from AWS to Nutanix. Nutanix may not consolidate applications, but it helps us run them more efficiently on its platform. Updating is simple with one click. I would rate the updating processes 10 out of 10. Adding compute and storage on demand is not difficult. However, we need to factor in the existing and new firmware and software requirements.

Quotes from Members

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

Pros

"The initial setup is pretty quick."

"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."

"It uses the same platform for connectivity so integration is seamless."

"The main feature I have found to be product replication."

"The most valuable features are the Metro clustering, and disaster recovery."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The solution provides many controllers."

"The initial setup is straightforward."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"Its technical support is excellent."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The most valuable feature are the caching capabilities using the storage class memory."

"The most valuable feature is that there is no single point of failure."

"The flash ability, in terms of tiering and caching, is amazing"

More Microsoft Storage Spaces Direct pros

"It has seamless expandability."

"Their Google operating system is more mature, so their results are much better."

"Nutanix Cloud Infrastructure's most valuable features are all the cloud facilities or benefits it provides for my data center."

"I can use VMware or Hyper-V license, if I already have. But if I use a similar solution as Nutanix Acropolis hypervisor (AHV) that comes embedded in Nutanix solution, I can manage all my virtual environments with everything I need without spend more money on licenses."

"The most valuable feature of Nutanix Acropolis AOS is it has centralized management."

"You need to send commands through the command-line interface(CLI). This could be improved. The commands are done better in VMware."

"This operating system offers stability. Setup is straightforward."

"The most valuable feature is the solution's ease of upgrading."

Cons

"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."

"Its configuration should be easier."

"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."

"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."

"The features provided for SMB customers are limited."

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

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

"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."

"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."

"Documentation management could be improved"

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

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

"It is difficult to get a hardware compatibility certification for the solution."

"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 Microsoft Storage Spaces Direct cons

"There is a need is to be able to consume Nutanix storage from outside the cluster for other, non-Nutanix workloads."

"Storage utilization and optimization should be better."

"As Nutanix Acropolis AOS is on the expensive side, one of its areas for improvement is the price. It would also be better if it can be integrated with other cloud providers, because currently, it's only for private cloud deployment."

"The One-Click Upgrade process could/should offer the ability to integrate with 3rd party drivers. For example, we use NVIDIA Grid graphics cards. It would be amazing if, during the One-Click Upgrade process, we could "slipstream" additional VIB drivers for ESXi into the upgrade process."

"I believe that improvements could be made in regards to the DR in addition to deduplication and integration with others platforms. They also do not offer opportunities for network virtualization so it would be nice to see that in the future."

"In terms of what I would like to see improved, I would say the life cycle management. I don't know if it is because they changed to an LCM from the previous way of upgrading the hardware or software but sometimes it feels that it needs a wizard that says, "Check this, check this," telling you your options. The only thing that's a bit frustrating for me is the life cycle management interface. That's the only thing on the entire system that frustrates me."

"For the company process, the price is too high."

"There is a feature that exists used for disaster recovery, but it requires an extra license. It should be included with the regular normal standard license."

Pricing and Cost Advice

"Licensing fees are paid yearly."

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

"The product is very expensive."

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

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

"Our customers have seen a reduction in TCO."

"Our licensing is renewed annually."

"The price could be cheaper."

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."

"The pricing is fair for the package."

"The price of the license for Nutanix Acropolis AOS is less expensive than the competition. There is a favorable cost saving. Having only the need to deal with a single vendor, the management of the customer's entire stack is cost-effective."

"When we purchase a new physical server or a couple of physical servers into our cluster, we always purchase it with Nutanix licensing. We are receiving the license from Nutanix directly and not from the vendor. In the way we're dealing, with the licenses it is a bit costly for us but as the company is getting larger, day by day or year by year, those licensing costs become lower each time for us. We are purchasing the licenses for three years for some of our clusters and for some others for five-year licenses and the licenses are still costly. We have good discounts for the licenses, but it is still expensive."

"This product is expensive, but they do have discounts. At one point, I saw that they were giving a 70% or 80% discount, which is a good thing, but maybe they should have a more realistic price and then a 5% to 10% discount."

"Setup cost is minor, pricing is quite a bit (we have a 7-node-cluster for about 450K EUR with 2 vGPU-nodes for Citrix) but that includes hardware, software, and support."

"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."

"We just have a support license for Nutanix."

"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."
