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.

Built-in compression enhances data management efficiency

MD.Faisal Alam

Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral

I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

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

"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."

"It is very easy to use, and it is very fast."

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

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

"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."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"The most valuable feature of this solution is performance."

"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."

"IBM offers excellent customer service."

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

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

"It has the ability to seamlessly move hardware in and out as we refresh technology."

"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."

"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."

"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."

More IBM Spectrum Virtualize pros

"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 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."

"One of the most valuable features is how well this solution performs. It's stable, aside from some patch issues, but it's great from a virtualization and scalability perspective."

"The most valuable features are the RBAC, role-based access control, and the reporting. NCI also provides a single platform, a single pane with a dashboard, to manage the entire infrastructure. We have complete information about overall utilization, performance, and a forecast for our platform in that single pane."

"Nutanix Acropolis AOS is flexible and has helped people to work from home during the pandemic."

"Single click actions is definitely the most important. They were not even aware that they wanted this."

"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."

"One major thing that comes up again and again is stability. Our downtime is literally based on hardware upgrades that need to be done. Acropolis is very, very user friendly. You don't have to physically have a super IT guy to manage the system. You can actually give it to a younger guy to manage and there won't be problems. And if he makes a mistake, it's very, very easy to fall back and sort out the mistake."

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 would like to see the licensing fees improved as well as the price per terabytes."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

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

"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."

"It's on the expensive side, as expected for a niche product."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"Adding features for data deduplication is one area of improvement."

"Level 1 technical support needs improvement."

"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."

"In general, the migration is complicated. Though, it is case-by-case."

"The Storwize port is not so stable."

"GUI should be developed in HTML5 as opposed to Java."

"The training program could be improved."

"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."

More IBM Spectrum Virtualize cons

"USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix."

"We did have some integration issues."

"They need to improve the look and feel of the interface. The functionality is fine, but the appearance could be better."

"Some clients find the solution's cost to be too high."

"I'm not very technical, so I don't know if there are any features that are really lacking. Our customers seem pleased with it, and I haven't heard of any downsides."

"I would like to see official compatibility with Red Hat in the future."

"We ran into an issue as a managed service provider because Acropolis isn't designed to be used the way we are running it. For example, if we want to deploy a Kubernetes service, the customer networks need to reach our protected cluster network. We have isolated our customers in separate VLANs. However, our customers' networks must access our cluster network to get features like iSCSI or Kubernetes to run. It's challenging."

"It would be great if it could emulate some of the features that their competitor VMware has, for example port mirroring or Netflow output at hypervisor level."

Pricing and Cost Advice

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

"The price could be cheaper."

"I rate the tool's pricing a seven to eight out of ten."

"The price is a little high."

"I understand that it is competitively priced compared to other brands."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"Licensing fees are paid yearly."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"I think it is a good value for the 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."

"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."

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

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

More IBM Spectrum Virtualize pricing and cost advice

"Nutanix Acropolis AOS is affordable, it has good value. The final price depends a lot on the hardware used, it's an appliance in the end. Whether you use HPE as the hardware vendor or Supermicro as the hardware vendor, it really depends on what hardware is used which is the main cost."

"Nutanix is cheaper than Cisco HyperFlex, although it depends on the configuration because Nutanix can also be expensive."

"The price of the solution is high."

"Reconsidering the licensing packages could reduce the price, especially for companies that may not need all the bells and whistles. Many of the features are based on open-source software, so there's potential to offer more flexible pricing options. Additionally, with the right expertise, companies could potentially create similar environments themselves, reducing the need for extensive support and licensing costs. I rate its pricing a six out of ten. The tool costs around 300,000 dollars per year."

"There are a lot of features included with Nutanix that cost a lot with other companies."

"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."

"The overall cost depends on the contract of each customer and the discounts they have, but the price for the three-tier architecture can be slightly lower."

"Nutanix Acropolis AOS price includes no additional costs for features."
