Featured Reviews

Eric Black

Solutions Architect at Recovery Point Systems

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.

Enterprise product that delivers high performance features

Virtualization Architect at Halm-IT

The primary use case is high availability and disaster recovery. They use it as an active-active cluster located in two physical locations for quick recovery using immutable snapshots The quick restore, the low latency, and the ease of use are some of the most valuable features. The product is…

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

"We have seen a reduction in the total cost of ownership by around 20%."

"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."

"The initial setup is pretty quick."

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

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

"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."

"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."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable features."

"It provides transparency, because of its advanced copy features."

"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."

"It lowers cost. It does so by getting more efficient use out of the technology behind it."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

"We are happy with the support that IBM provides us."

More IBM Spectrum Virtualize pros

"The most valuable feature I have found to be the Acropolis Hypervisor (AHV)."

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

"Nutanix Acropolis AOS is easy to use, integrates with other hardware configurations, and is simple to manage."

"The level of statistical performance data that it can confirm in real-time is extremely useful. I can see what my VM’s hosts and guests are doing from a single pane of glass and identify issues before they would otherwise become apparent."

"The solution is easy to use and the pricing is affordable."

"Everything is core centralized on the UI."

"Nutanix has several unique capabilities to ensure linear scalability."

"The hyperconvergence service, as well as the DR solution, are game-changers for Nutanix."

Cons

"Its configuration should be easier."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"They need better integration with public clouds along with a better hybrid solution."

"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."

"I have not seen ROI."

"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."

"The solution is expensive."

"I would like to see more deduplication."

More Pure Storage FlashBlade cons

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

"The Storwize port is not so stable."

"IBM could improve IBM Spectrum Virtualize by bundling Storage Scale and Storage Virtualize into a single appliance. This would provide a more appealing and cost-effective solution."

"Level 1 technical support needs improvement."

"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."

"Anything which improves performance and the ability of our systems would be a nice."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."

More IBM Spectrum Virtualize cons

"It was not a great fit for really large databases that required high-end or lots of compute. They might already have addressed this concern around very high-end databases that require high-end compute. In the past, it wasn't a great fit for them."

"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better."

"Storage utilization and optimization should be better."

"It would be great if they could improve the GUI features."

"NCI's pricing is expensive."

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

"Compatible with third party hardware, but it's still very limited."

"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant. The software-defined networking is quite limited, and we usually use other products to do that. We're aware that Nutanix is working on that and will be coming out with better solutions, and we can't wait because to do a fully software-defined architecture, the abstraction layer needs not only software-defined storage, which you have, but also the software-defined networking piece."

Pricing and Cost Advice

"Our licensing is renewed annually."

"The price of this solution could be made more affordable."

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

"The price is a little high."

"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."

"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."

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

More Pure Storage FlashBlade pricing and cost advice

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"Do a proof of concept, if you are not comfortable jumping in, but do it."

"It has a lot of advanced functions for a reasonable price."

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"The entry point of pricing for this product is the most amazing price ever in the industry."

"This solution came as an additional cost for the TSM package we chose."

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

"We would like the CPU cycle to save more on the licensing costs for us."

More IBM Spectrum Virtualize pricing and cost advice

"The software only licensing model is priced normally, but the licensing model that comes with hardware is priced very high. You can choose to pay the license yearly, or you can pay every three years, or every five years."

"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."

"The initial cost is affordable but the renewal fees are high."

"The solution is quite expensive."

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

"While cost may seem higher than your traditional 3-tier architecture, you need to look at the bigger picture. You're not just buying hardware here. You're buying a complete environment."

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

"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."
