Featured Reviews

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 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

"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 has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."
"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."
"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 feature of this solution is performance."
"The solution provides many controllers."
"I would rate Pure Storage FlashBlade a ten out of ten."
"The onboarding and integrated monitoring tools are pretty good."
"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."
"Customer service is awesome. I would rate it ten out of ten."
"To receive a performance enhancement by merely clicking the one button upgrade is the true value of the platform and what I look forward to the most."
"The most valuable feature of Nutanix Acropolis AOS is it has centralized management."
"You can be sure that whatever you patch is already compatible with the current firmware and the current version of the Acropolis that you're using."
"Technical support is okay."
"Single-click upgrades are the most valuable feature. In the sector in which we work, it is tough to have downtime and arrange firmware upgrades."
"SRM capabilities for replication have been proven reliable and very useful for our organization."
"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."
 

Cons

"I would also like to see better support for CIFS workloads."
"The documentational aspect of FlashBlade needs improvement."
"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."
"I would like to see more monitoring capability included in the next release of this solution."
"Pure Storage FlashBlade should improve on more cloud integration."
"There could be improvements in public cloud integration."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"The reporting mechanisms need improvement."
"he interface is not user-friendly so the ease of use could be improved."
"In a hybrid cloud setup, we should be able to port our floors from on-premises to the public cloud and from the public cloud to on-premises."
"Native File-Services are under heavy development and Container Services just came out."
"While their overall Nutanix Bible is good, they are lacking good descriptions for particular scenarios that might be helpful to many users."
"For the company process, the price is too high. We need to purchase add-ons for the extra key and extra terabyte."
"Make it easier to manage."
"There is a lot of functionality in Prism Central, but sometimes you want to see those features in Prism Element."
"Some clients find the solution's cost to be too high."
"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

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"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."
"The pricing for FlashBlade is between cheap and moderate."
"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 rate the tool's pricing a seven to eight out of ten."
"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."
"The price is a little high."
"If you are cost-sensitive then this solution is not for you."
"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."
"There are a lot of features included with Nutanix that cost a lot with other companies."
"The price of the solution is high."
"Cost-wise, it is very good. It is like the hypervisor cost is not there. We only need to pay for the system and AOS licenses."
"Licensing depends on the features needed."
"We just have a support license for Nutanix."
"The price is good but I think there is still room for improvement on the price."
"Nutanix Cloud Infrastructure's pricing is higher now."
"Their technical support is really good. They have been very helpful."

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…
