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.

Unified storage solution supports cross-vendor replication and diverse industries

AhmedSorour

IT Specialist at Saudi Business Machines - SBM

One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

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

Obasanjo Biliaminu

Head Systems Administration/Security at Nigeria Inter-Bank Settlement System PLC

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

"It performs well and it is also very fast."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

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

"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."

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

"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 this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"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."

"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."

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

"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."

"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."

"We can failover easily, because a lot of our data is replicated from family to the second replication."

"IBM offers excellent customer service."

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

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

More IBM Spectrum Virtualize pros

"A great feature involves real-time hardware changes."

"One of the most valuable features is that it can be applied at any scale."

"Nutanix Acropolis AOS makes it easy to use and manage projects and it has a good reputation."

"The infrastructure has improved our turnaround time."

"Technical support is okay."

"It supports multi-cloud integration that includes AWS, Google, and Azure."

"The flexibility of this system is very good. It's also faster than others, and has skilled technical support who showed more initiative than a competitor, e.g. VMware."

"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."

Cons

"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."

"Its configuration should be easier."

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

"The documentational aspect of FlashBlade needs improvement."

"There could be improvements in public cloud integration."

"Its configuration should be easier."

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

More Pure Storage FlashBlade cons

"The case logging process is efficient, but resolving software problems takes too much time."

"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."

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

"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."

"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."

"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."

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

"The training program could be improved."

More IBM Spectrum Virtualize cons

"There are other services that Nutanix has that could be improved, but I'm not very familiar with the other services of Nutanix, such as Era and Flow. However, they seem a bit hard for us to implement and integrate with the Nutanix Acropolis AOS and other Nutanix tools. We would not dare to implement those other Nutanix solutions into Nutanix Acropolis AOS right now. The implementation of that tool could be the problem, I am a bit hesitant to implement the other tools into Nutanix Acropolis AOS."

"Regarding third-party backup solutions, the only agentless option is Commvault, which is expensive, complex, and requires intensive vendor training."

"If we can have certified compatibility with other companies, such as Oracle, then it would let us know that they function correctly together."

"The documentation could be improved."

"I would like to see them utilize the spare storage that they use as a redundant space. I feel that now a lot of resources are wasted just for standby purposes because we are using data protection. Instead of utilizing those resources only when something happens, they can have an alternative so that we can utilize these resources all the time."

"The name of the solutions offered by Nutanix does not indicate what the tool does."

"This solution would be improved with built-in integration with Rubrik."

"As far as what could be improved, they have some built-in backup functions already, but any built-in isolation features like vision security features and free LAN features become a security concern."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"We used a reseller for the purchase."

"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."

"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."

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

"Licensing fees are paid yearly."

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

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

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."

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

"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."

"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."

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

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

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

More IBM Spectrum Virtualize pricing and cost advice

"Nutanix Cloud Infrastructure's pricing is higher now."

"It is less expensive than the VMware alternative."

"We are aware of the pricing since we renew every year, at almost $100,000 per year."

"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."

"In terms of the solution's licensing, it's quite comprehensive."

"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."

"The price of the solution is high."

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