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.

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 a unified platform, reduces downtime, and simple updates
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 easy and simple."
"The most valuable feature of this solution is performance."
"I would rate Pure Storage FlashBlade a ten out of ten."
"Speed and ease of use are the two most valuable features."
"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."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"Using this solution has made our backups more reliable."
"It's very easy-to-use."
"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 solution is easy to use and the pricing is affordable."
"The solution is well integrated with other vendors."
"It gives us a single dashboard to control multiple sites and multiple zones. It helps to do things on a single platform and data sharing is quite easy. The network and the security are easy to manage."
"The technology of Nutanix Acropolis AOS is the most valuable feature. You don't need multiple screens to manage."
"The best feature of Nutanix Acropolis AOS is the central management of all of our resources. Additionally, it is easy to use"
"It has solid performance and provides data locality."
"The most valuable feature is the integration of all parts in Prism Element, the browser-based management tool."
"The scalability is great."
 

Cons

"There could be improvements in public cloud integration."
"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."
"The documentational aspect of FlashBlade needs improvement."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"Pure Storage FlashBlade should improve on more cloud integration."
"I would like to see more VM-Aware features in the next release of this solution."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"The reporting mechanisms need improvement."
"he interface is not user-friendly so the ease of use could be improved."
"One thing to keep in mind is that only experts can use it. It has to be in the proper hands, instead of going to XYZ people just for some cost savings. So lift-and-shift and migrations might be tricky, because it is not like a VMware."
"They have offered some new features that I have not deployed so I assume that these issues might have been addressed already, but, at my time there was a networking problem."
"In the future, I would like to see integration with external storage using the fiber channel"
"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."
"The documentation could be improved."
"The pricing model for software and hardware subscription renewals can be improved."
"I think some of the tasks that must be done using CLI could be added to the web interface."
"Nutanix Cloud Infrastructure's cloud platform management software could be improved so that I can manage my load between the cloud and on-premises."
 

Pricing and Cost Advice

"The price of this solution could be made more affordable."
"I rate the tool's pricing a seven to eight out of ten."
"The pricing for FlashBlade is between cheap and moderate."
"I understand that it is competitively priced compared to other brands."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Licensing fees are paid yearly."
"Our customers have seen a reduction in TCO."
"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."
"Pricing varies greatly between license and editions."
"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."
"Nutanix price is high because it bundles all the components into single deals rather than allowing you to select the features that you want/will use."
"Its price is fine. I can't really complain about that."
"Nutanix Cloud Infrastructure could be cheaper. It's costly to upgrade the solution. There are no additional costs aside from the license."
"Nutanix Cloud Infrastructure's pricing is higher now."
"This product is less expensive than some of the competing HCI solutions."
"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."

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…
