Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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.

Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool

From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.

Quotes from Members

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

Pros

"FlashBlade offers low latency, high throughput, and seamless scalability."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

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

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

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

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

"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 most valuable feature is the robustness, which is typical of IBM because their software generally just works."

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

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

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

"Scaling is very easy and no limitations are set."

"What's best about Nutanix Acropolis AOS is its simplicity. It's simple to install and simple to understand. The technical support and support portal for this product are both very good and very helpful."

"The feature that I have found most valuable is its software Move, which we use to migrate virtual info from another platform to the Nutanix platform."

"There are a lot of features in Nutanix that are different from other hyper-converged solutions, such as site-to-site replication. VM-based site-to-site replication is bundled with the software licensing. For the DR, it has the availability groups, which is one of the key features that Nutanix provides."

"Technical support is okay."

"The solution is very stable. We haven't had any issues."

Cons

"I would like to see better integration."

"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."

"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."

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

"The features provided for SMB customers are limited."

"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 want efficiency. FlashBlade doesn't have efficiency now."

"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."

More Pure Storage FlashBlade cons

"The reporting mechanisms need improvement."

"he interface is not user-friendly so the ease of use could be improved."

"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."

"The product needs improvement in the areas of SAN attachment for high capacity and high I/O profile workloads."

"The file services that they also provide need some more features, like on the Windows file server."

"In the next release of this solution, they could improve by being more competitive with VMware. I would like all third-party solutions to work well with Nutanix Acropolis AOS."

"In the future, I would like to see multi-tenancy in Nutanix Acropolis AOS."

"Notifications could be improved as they're not currently very useful."

"One of the very important things that I would like to see in Nutanix, but I'm not sure if it's in the roadmap or not, is to have some kind of caching optimization at remote sites, to build active-active data centers more easily."

"Nutanix Acropolis AOS could improve by adding some NAS features, similar to the ones that are available in the NetApp solution."

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."

"Licensing fees are paid yearly."

"The price is a little high."

"I feel that the price could always be lowered."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

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

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"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."

More Pure Storage FlashBlade pricing and cost advice

"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."

"The solution could be a little less expensive."

"Our Nutanix license is for five years. There is a support arrangement there, but that aspect is more or less taken care of during the initial installation. With HCI architecture, whenever we do any kind of auto scaling or scaling of servers and resources, there is a significant amount of software licensing involved."

"If a customer has been using VMware, the difference in pricing is lower. However, if they are looking to use the VMware, the price can be much higher depending on the license."

"Its licensing is fine. They provide the flexibility to choose from different options. You can go with the standard plan. You can go with the pro or platinum plan. Generally, our clients go with the pro licenses, but if you go for the platinum license, you get even more capabilities. Their starter license is also quite good."

"It's a bit expensive, but it's worth it."

"Its price is fine. I can't really complain about that."

"The price of the solution is expensive. However, the price to performance is good. The cost for development and installation is very low."

"The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."
