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.

Achieve cost-effectiveness with superior performance while needing to address cluster support
I am working with Microsoft Storage Spaces Direct for applications, SQL, and VRS. I am an integrator for this solution The price performance is the best advantage of Microsoft Storage Spaces Direct. They introduced the All-Flash array using SSD or NVMe drives without cache drives. It is…

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

"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."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"I would rate Pure Storage FlashBlade a ten out of ten."
"It is very easy to use, and it is very fast."
"The most valuable features are the Metro clustering, and disaster recovery."
"The initial setup is pretty quick."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"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."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The most valuable feature are the caching capabilities using the storage class memory."
"The performance, reliability, and affordability has been most valuable."
"Its technical support is excellent."
"The most valuable feature is that there is no single point of failure."
"The flash ability, in terms of tiering and caching, is amazing"
"It allows us to have a cloud-based ecosystem."
"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."
"The dashboard of Nutanix Acropolis AOS allows for simple management. The dashboard has all the information online about what's going on at any given time."
"It is easy to use. One of the things they have as a design goal is to reduce complexity and simplify things."
"Flexibility. We're able to mix performance nodes with storage nodes easily. Unlike other vendors where, if we start a hyperconverged solution with them, we have to stick to a specific model, to a specific series with specific capabilities, with Nutanix it's very easy to mix and match the best solution, especially for a dynamic infrastructure like ours."
"Being able to upgrade our entire cluster with the click of a button during business hours with zero downtime has made managing our infrastructure so easy."
"Nutanix Acropolis AOS is stable. We didn't receive any concerns regarding any problems, The customers have no concerns about the reliability."
"Nutanix Cloud Infrastructure has a simple, user-friendly GUI, and I also like the remote recovery capabilities. It provides a single platform for managing databases."
 

Cons

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"I have not seen ROI."
"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."
"They need better integration with public clouds along with a better hybrid solution."
"I want efficiency. FlashBlade doesn't have efficiency now."
"Its configuration should be easier."
"I would like to see more monitoring capability included in the next release of this solution."
"It would be nice if you could store file-based in the same box with the same technology."
"Documentation management could be improved"
"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."
"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."
"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."
"Microsoft closed the shared cluster support, which is important for the solution."
"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."
"More optimization could be done in terms of mirroring."
"The product needs improvement in the areas of SAN attachment for high capacity and high I/O profile workloads."
"The GUI of Nutanix Acropolis AOS could be improved that can be done from the OEM side. It's a very basic stable web browser that they're using. It is not very inclusive."
"In the future, I would like to see multi-tenancy in Nutanix Acropolis AOS."
"Nutanix Acropolis AOS could improve by having an auto-update feature. At this time I have to update each system manually. However, I bought the standard license and I did not buy the maximum license they have available. There could be a certain license that does the updates automatically."
"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."
"The patch updates of Nutanix Acropolis could be improved. I'm work on the corporate side, but I get feedback from our IT team that patch updates and other updates are taking a significantly longer time. This definitely needs to be resolved. We are in discussion with Nutanix regarding certain configuration issues we are having, so maybe something can be changed to ease these patch updates."
"There could be better support for high power ESX and other cross platform applications."
"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."
 

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."
"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."
"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."
"The product is very expensive."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I rate the tool's pricing a seven to eight out of ten."
"Our licensing is renewed annually."
"Cost-wise the product is one of the more affordable within the category of products."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"The solution is expensive."
"Nutanix Cloud Infrastructure’s pricing is very good and competitive."
"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."
"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."
"There are a lot of features included with Nutanix that cost a lot with other companies."
"They should lower the price. If they did they would fall into a more competitive market because the price does scare a lot of potential customers away when they get the quote."
"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."
"The one disadvantage is relative, financially Nutanix Acropolis AOS is a little bit more expensive than the old solution."

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…
